Height Requirements For Certain Jobs In China

Me: I was going through google and I found a rather in depth look at the psychological and social aspects of how the issue of height affects the people of China. In it, I actually found a few height requirements. Some of the height requirements look really high but maybe it is just for the city of Shanghai, which is known to be a rich cosmopolitan city.

My Personal Opinion: This is a clear example for the Chinese practicing selective eugenics and social discrimination. Throughout the history of the western world, I would assume most tribes and nations discriminated on social standing and economic reasons but it seems that the Chinese are taking social stratification to a new level. While the phenomena of heightism does exist in the world, at least in the western nations people of short stature are not so publicly derided and mistreated. In places like China and Korea, short stature is made fun of quite blatantly and publicly. If the implementation of height requirements is enforced, then the old Confuscian belief of rising above one’s social level through hard work and merit is contradicted since height is mostly a genetic thing, some few of us can control. A person can be given everything in life just because they were lucky in the genetic lottery and came from a tall family giving them opportunities a person who might be smarter and harder working would never get. This issue should be address and tackled for the other half of the world population which are below the 50% percentile of height.

From the article…

A search on Chinese job sites reveals height minimums in many fields. Some companies require their workers, male or female, to be at least 165 cm tall. Sales consultants in some companies are required to be a minimum of 170 cm for men, 165cm for women. A number of Chinese universities have similar height requirements: Hebei University requires journalism students to be at least 170 cm for men, 160 cm for women. Anhui University has a height minimum of 168 cm for men and 158 cm for women who want to major in Chinese language, history, philosophy or media studies. For Shanghai’s police force, men must be at least 168 cm and women 158 cm. More exotic jobs like TV hostesses require a 164 cm minimum.

Sales: Men – 170 cm  &  Women – 165 cm

Hebei University students: Men – 170 cm & Women – 160 cm

Anhui University students: Men – 168 cm & Women – 158 cm (Only for majors Chinese language, history, philosophy or media studies)

Shanghai Police Force: Men – 168 cm & Women – 158 cm.

TV Hostesses (women): 164 minimum

Break a leg

by hart @ Wed, 22 June 2011 03:00
Shanghainese pursue greater heights with extreme leg-lengthening surgery.

At Renai Hospital, just across the road from IKEA, Dr. Li Rongguo (李龙国) saws apart his patient’s shin bones and then screws the severed tibias and fibias to external metal braces with pins, rods and wires. After being bedridden for a week with agonizing pain only dulled by heavy sedatives, the patient’s long slow journey begins. Three times a day for up to 16 months, the bone-embedded screws must be manually turned, extending the fracture to encourage new bone growth. This may sound barbaric, but it’s China’s most successful method of leg-lengthening, a surgical procedure which is proving increasingly popular among Shanghainese.

Dr. Li is Renai’s world-renowned director of orthopedics with a medaled military background. Patients are referred to him from all over the world in the hope that he can fix their legs crippled by disease, mangled in
accidents or, in an increasing amount of cases, are simply too short for their owner’s liking. In the past decade, Li has performed over 1,000 leg surgeries, and while he won’t say how many are purely cosmetic, he says the pursuit of height is on the rise. His cosmetic patients range from 20 to 40 years old, divided equally between men and women, most of them with university degrees.

Li says the increasing interest in cosmetic leg-lengthening surgery (接骨再生), which costs around RMB100,000, can be attributed to several factors. “First, people earn more money in China now, so they can afford the surgery,” he says. “Also, my patients mostly have low self-esteem and less opportunity in society. It’s hard for them to find a good job.”

In a country where hundreds of qualified candidates are applying for each vacant position, a minimum height requirement is an effective way for an employer to weed out prospects. A search on Chinese job sites reveals height minimums in many fields. Some companies require their workers, male or female, to be at least 165 cm tall. Sales consultants in some companies are required to be a minimum of 170 cm for men, 165cm for women. A number of Chinese universities have similar height requirements: Hebei University requires journalism students to be at least 170 cm for men, 160 cm for women. Anhui University has a height minimum of 168 cm for men and 158 cm for women who want to major in Chinese language, history, philosophy or media studies. For Shanghai’s police force, men must be at least 168 cm and women 158 cm. More exotic jobs like TV hostesses require a 164 cm minimum.

Li cites another reason for the surgery: love. “Many of my patients undergo this surgery to find love and marriage. You’re considered more attractive in China when you’re taller.”

One of Li’s former patients, Ms. Wang, a 23-year-old woman from Jiangsu who gained seven centimeters in height with surgery, is just one of many of Li’s patients thrilled with the end result.

“It’s amazing. My life is changed forever,” she gushes. Why did she do it? “First, to find love. I have a boyfriend now!“ she says, beaming.

When Wang underwent the surgery in 2008, she kept it from her family. “I didn’t tell my family because I knew they would worry. At the time, I was already living away from home, so I saved my money and got the surgery secretly. I lived in an apartment by myself and studied English for six months as I healed. When I finally came home, the braces scared my parents for a while, but now they’re happy for me.”

Isolation and secrecy is common because the extreme surgery, not surprisingly, is taboo in China. Thus, many patients go through the entire process alone, healing in a cheap apartment near the hospital for six months to a year, occupying themselves, just as Wang did, by learning English or taking online jobs. But a substantial post-puberty growth spurt can’t be concealed forever. When they finally return home, Li says, “Patients often reappear in front of everyone claiming it’s just a miracle that they grew taller.”

Foreigners, too, are having leg-lengthening surgery in Shanghai. Last year alone, 10 foreigners from Germany, the United States, Korea and Japan came to Renai. “I believe China is leading the way in leg-lengthening surgery. Every country has different methods of leg-lengthening, but ours is the most advanced,” says Li, referring to the Micro-Wound method, the procedure used at his hospital.

Pioneered by Dr. Bai Helong (白鹤龙), a member of China’s National Orthopedics Council, the Micro-Wound method is a simplified version of the original pioneered by Russian orthopedic surgeon Gavril Abramovich Ilizarov in the 1950s. In the Ilizarov method, surgeons break the tibia and fibia and then set a stainless steel circular frame around the leg by fixing the top and bottom rings to the bones though tension wires. The frame relieves the fracture site of stress while also enabling movement of the entire leg.

Instead of the cage-like Ilizarov apparatus, the Micro-Wound method uses a simpler fixative clip that covers just one side of the leg. With fewer parts involved, there is less trauma and disturbance of surrounding tissues, nerves and muscles.

Besides Micro-Wound’s successful reputation, another major draw to get the surgery in China is the low cost. The same procedure in the US with a doctor of Li’s caliber would cost US$80,000-140,000 (RMB500,000-900,000).

In November 2006, the Chinese Ministry of Health banned leg-lengthening surgery “for the image conscious.” Ministry spokesman Mao Qunan said at the time, “Leg-lengthening surgery is a clinical orthopedic treatment, not cosmetic surgery… It must only be carried out for strict medical reasons and performed in authorized hospitals.”

One strict medical reason can be height-related stress, according to an orthopedic clinic in Beijing. The clinic’s English website informs prospective patients, “We would like you to keep a low profile about your cosmetic lengthening surgery… When asked by the related authorities (highly unlikely), it will be helpful that you could admit to suffering from height-related stress, so that the surgery is more justified on medical grounds.”

At the time of the ban, unqualified doctors carried out the risky operation in unauthorized beauty clinics. One story recounts a woman, Zhang Wen, who paid a doctor RMB20,000 in Chongqing when she discovered she was just four centimeters short of the 1.6 meter height minimum to be an Air China flight attendant — her dream job. The shady doctor botched the surgery, leaving her with a debilitating limp and not enough money for corrective surgery.

Li claims his success rate is 100 percent and remains in good standing with Chinese Ministry of Health.

Method to the Madness

Dr. Li saws through the tibia and the fibia below the knee without touching the bone marrow, then fixes braces made of nickel and titanium to the legs by screwing them into the bone.

Post-op, the patient is bed-ridden for a week and given painkillers. Patients can usually walk again with elbow crutches after a week. By then the bones begin to regenerate.

After the first week, most patients go off of painkillers, which are thought to adversely affect bone growth. To reduce risk of infection, patients cannot wash their legs and are given antibiotics.

To grow six to eight centimeters, patients must wear braces for one year up to 16 months, manually turning the screws three times daily to extend the fracture 0.55 milli-meters per day.

Every two months, the patient returns to the hospital for X-rays to track if the bones are regenerating evenly. After five months, Li will adjust the brace to ensure even growth.

After desired height is achieved, the patient undergoes a second surgery to remove the braces. The new bone is just strong enough for walking, but the patient should wait another year to do any strenuous activity.

Buying Bone Lengthening External Orthopedic Surgical Fixations From Meditech Of Changzhou China

Me: I guess this post will be to show where you can actually buy the medical equipment for external orthopedic surgical fixations on Alibaba without the need for being a medical professional. For most suppliers of medical products like devices, the manufaturer or supplier would ask you to call them through a hospital or clinic line to show you are a doctor or associated with the medical establishment. It seems this company in China will sell to buyers as long as they are willing to buy at the bulk quantities that Alibaba has set up for them.

Obvious nobody would be crazy enough to perform limb lengthening surgery on themselves since they are not qualified, don’t have the know how, and are not crazy. The supplier might be someone we could talk to if we ever decide to test any distraction techniques on sow (sheep) or pig subjects. However, we would get into a lot of trouble with many regulation and animal rights organizations like PETA. It is still good to know that if we needed the external fixators for testing and experiments, we have a company which can provide us with the needed parts.

The company is named “Changzhou Meditech Trading Co., Ltd.” from Jiangsu, China.

You can go to the section for External Fixators HERE. I only decided to copy and paste two of the over 20 products you can find on the company website here. You can have the fixators that are not rings and the ones that are ring based.

China Banned Leg Limb Lengthening Surgery In 2006

Me: I remember reading from the Make Me Taller forum that the practice of leg and limb lengthening surgery was banned in China. However, that has not stopped some medical professionals from still setting up clinics in China to perform the limb lengthening surgery still. If I remember correctly the Chinese doctor Bai Helong who came up with what he said was a minimally invasive and NON-PAINFUL procedure had some trouble with the Chinese government and relocated his practice around to where I heard was in Shanghai last time. If I was to guess, the lure of the money will cause some doctors or people with medical degrees to be willing to go against the law and perform the surgery still for the many millions of people who would break the law for extra height.

China Bans Illegal Leg-lengthening Surgery
  2006-11-04 22:34:30      AFP
China has banned leg-lengthening surgery that a largely unregulated beauty industry has been offering to customers who want to be taller.”Leg-stretching surgery for the image conscious has been banned by China’s Health Ministry after a spate of botched operations,” the Xinhua news agency reported Saturday.The operation involves breaking the patients’ legs and stretching them on a rack, and has led to several cases of disfigurement, Xinhua said, citing the health ministry.

Hospitals that conduct at least 400 orthopedic operations a year and offer post-surgery care and rehabilitation will be allowed to carry out such operations in future, but only on strictly medical grounds, according to a ministry circular.

The surgical procedure, popular among young Chinese professionals who believe height will help them climb the career ladder, was developed in Russia to help patients with birth defects such as dwarfism.

Botched operations carried out by unauthorized beauty clinics have left many patients physically and psychologically scarred, Xinhua said, without detailing the injuries.

Ten people, enticed by a promise of “height surgery without pain,” were reported to have been disfigured after they underwent the operation last year at a Beijing hospital.

The health ministry said hospitals must in future tell patients about the risks involved, while only qualified personnel would be allowed to carry out the procedure.

Low Magnitude, High Frequency Mechanical Stimuli Are Anabolic And Osteogenic To Trabecular Bone In Children

Me: This study helps in showing that even at low magnitudes for mechanical loads, as long as it is of high frequency the trabecular bones can have an anabolic effect. This pushes the idea further to show that the high magnitudes for loading which I had proposed before may not be needed and may be easier to create such a bone loading device than previously believed.

Analysis & Interpretation:

It would seem that for just s short amount of time with even small magnitudes in bone loading we find that the bone mass density (BMD) can be increased in kids who are still developing. The only thing that seems to be very important is to make the loading have high frequency.  The researchers wanted to test the loading on both the proximal tibia and spinal vertebrate area for bone mass density changes. The results showed that it was effective.

Implications For Height Increase:

This shows that at least for developing children, changing their bone density from low , which indicates bone fragileness, to high which would indicate strength and like chance for fractures is rather easy and quick to do. So many physicians have worried about the fact that many of the height increasing methods we have looked at may be bad for bone density since they can decrease BMD leading to weaker bones. This shows that their overall worrying and concerns about the loss of bone density is not really valid. We saw from a few of the recent posts with looking at the effect of chronic starvation, illness, and inflammation that the band or area of band actually increases in bone density in a developing child’s bone when analyzed histologically, however the longitudinal gorwth rate becomes slightly stunted during that phase.This means that when we are looking at any height increase idea or method we would not need to worry too much about the loss or effect on bone density. Bone density can be rather easily increased with this type of low magnitude high frequency loading or from taking certain bone increasing pills like statin.

As always let’s remember that this type of loading is very similar to the LSJL idea with the effect being bone growth or bone increase. However we are not really looking for bone growth, but bone lengthening. That requires cartilage. This would slightly infer that the chance of using the LSJL in children with their growth plates intact might be effective in increasing the rate of their longitudinal growth of long bones, ie. make them taller.

Abstract

The osteogenic potential of short durations of low-level mechanical stimuli was examined in children with disabling conditions. The mean change in tibia vTBMD was +6.3% in the intervention group compared with -11.9% in the control group. This pilot randomized controlled trial provides preliminary evidence that low-level mechanical stimuli represent a noninvasive, non-pharmacological treatment of low BMD in children with disabling conditions.

INTRODUCTION:

Recent animal studies have demonstrated the anabolic potential of low-magnitude, high-frequency mechanical stimuli to the trabecular bone of weight-bearing regions of the skeleton. The main aim of this prospective, double-blind, randomized placebo-controlled pilot trial (RCT) was to examine whether these signals could effectively increase tibial and spinal volumetric trabecular BMD (vTBMD; mg/ml) in children with disabling conditions.

MATERIALS AND METHODS:

Twenty pre-or postpubertal disabled, ambulant, children (14 males, 6 females; mean age, 9.1 +/- 4.3 years; range, 4-19 years) were randomized to standing on active (n = 10; 0.3g, 90 Hz) or placebo (n = 10) devices for 10 minutes/day, 5 days/week for 6 months. The primary outcomes of the trial were proximal tibial and spinal (L2) vTBMD (mg/ml), measured using 3-D QCT. Posthoc analyses were performed to determine whether the treatment had an effect on diaphyseal cortical bone and muscle parameters.

RESULTS AND CONCLUSIONS:

Compliance was 44% (4.4 minutes per day), as determined by mean time on treatment (567.9 minutes) compared with expected time on treatment over the 6 months (1300 minutes). After 6 months, the mean change in proximal tibial vTBMD in children who stood on active devices was 6.27 mg/ml (+6.3%); in children who stood on placebo devices, vTBMD decreased by -9.45 mg/ml (-11.9%). Thus, the net benefit of treatment was +15.72 mg/ml (17.7%; p = 0.0033). In the spine, the net benefit of treatment, compared with placebo, was +6.72 mg/ml, (p = 0.14). Diaphyseal bone and muscle parameters did not show a response to treatment. The results of this pilot RCT have shown for the first time that low-magnitude, high-frequency mechanical stimuli are anabolic to trabecular bone in children, possibly by providing a surrogate for suppressed muscular activity in the disabled. Over the course of a longer treatment period, harnessing bone’s sensitivity to these stimuli may provide a non-pharmacological treatment for bone fragility in children.

A Non-Surgical Method for Repairing Damaged Cartilage Using Viral Delivery Of Genes Encoding Growth Factors (Breakthrough)

Me: This for me is a huge breakthrough in the application of being able to combine the fields of genetic engineering, tissue engineering, and gene therapy. What we are seeing is that a single injection of growth factors, which are just proteins, when slightly altered from genetic engineering can then be injected onto the surface of the articular cartilage of the knee and result in cartilage formation meaning that more invasive approaches like using arthroscopy and/or microfracture surgery may not be needed for healing.

This proves the idea which I had proposed earlier that we can possibly cause cartilage to form just from an injection of growth factors into bone. At this point, the information is little but I am still a little confused on whether it is growth factors or genes which are injected into the knee area.

Let’s remember from our studies on pathways like the Wnt/Beta-Catenin, PI3K/ATK/mTOR, and MAPK signaling pathways like growth factors themselves are proteins, not cells. They act as ligands or substrates for the communication between the outside and inside of a cell outer membrane. We find that a lot of the growth factors we are familiar with like the TGF-Beta, BMP, GDF, IGF-1 don’t reach into the cell but only bind to receptors on the cell wall on the outside, which cause a certain pathway in the protoplasm/cytoplasm to be initiated. The signaling causes the nucleus to receive different types of signals resulting in certain genes being turned on or off.

Update 2/14/2013

After looking back at the claims and information made on this patent I found I have reached the conclusion that the injection of delivery is only growth factors, not genes. It would seem that the growth factors, in whatever combination or mixture they are in, gets injected to the surface or slightly underneath the surface of the articular cartilage which is starting to degenerate/deteriorate. The growth factors touch the cartilage, resulting in the diffusion effects which means the growth factors manage to get past the cartilage’s protective layers like the 2 layered perichondrium. The cartilage itself is not cell packed like so many other tissue but has the chondrocytes rather scattered around. It would require that the growth factors diffuse and seep around the extra-cellular matrix until they reach the surface of the chondrocytes. The chondrocytes themselves have certain receptors on the cell membrane which are willing substrates to the substrates/ growth factors. The growth factors will link to the receptor forming a complex, and causing the chondrogenetic signal pathways to begin. The signalling reaches to the nucleus, causing the genes that make the proteins for growth factors and mitosis possible. The cells also multiple resulting in more waste from the chondrocytes released, being collagen and proteoglycans. The net result and effect is that over time the cartilage manages to reform back. The thing I am wondering at this point is whether the cartilage that is formed is maybe the less fibrous arranged fibrocartilage or is it the hyaline cartilage that the researchers and us have been hoping for.

Implications For Height Increase:

This suggest that one of the critical steps in one my old proposed ideas on height increase is possible. However the existence of some cartilage already there for cartilage seed building makes it show that the 2nd step is possible, but the 1st step needs to have more research. WE can inject growth factors into the epiphysis but without the cartilage already there we may not form the type of cartilage culture or colony we want for possible a pseudo growth plate regeneration.

A Non-Surgical Method for Repairing Damaged Cartilage In the Knee: Viral Delivery of Genes Encoding Growth Factors

A Non-Surgical Method for Repairing Damaged Cartilage In the Knee: Viral Delivery of Genes Encoding Growth Factors

Full description

Introduction/Background

Annually, more than 2 million Americans injure cartilage in their knees. There is a range of existing treatment options from arthroscopy and microfracture to osteochondral implant and autologous cell implant available to patients to repair damaged cartilage. In each of these cases, treatment requires invasive surgery and a substantial amount of rehabilitation.

Aims/Hypothesis

From a commercial perspective, a non-invasive treatment option would provide patients with a significant improvement over existing therapies and would likely become a front line therapy for repairing damaged cartilage.

Research 

Dr. Ernest Terwilliger and Dr. Magali Cucchiarini have developed a new method of repairing damaged cartilage tissue without the use of invasive surgery. Their novel method utilizes viral delivery of genes encoding growth factors that enable regeneration and repair of damaged cartilage tissue in the knee. In a rabbit animal model of cartilage damage Drs. Terwilliger and Cucchiarini have shown that delivery of a particular class of viral vectors encoding specific growth factors to the injured knee greatly promotes the cartilage regeneration and repair process.

Conclusion

Arthroscopy, microfracture, osteochondral implant, autologous cell implant and total knee replacement to repair damaged cartilage require invasive surgical procedures. This novel method developed by Drs. Terwilliger and Cucchiarini requires a simple injection at the site of injury, which would be considerably more desirable for the patient than invasive surgery.

Relevance/Opportunity

A Provisional US Patent application is pending. BIDMC is seeking a corporate partner to develop and commercialize the technology, which is available for licensing on an exclusive basis. In particular, Dr. Terwilliger is seeking support for additional preclinical experiments, potentially including large animal mammalian models, and eventually human clinical trials. Please enquire quoting reference no. 838.

Increase Height And Grow Taller Through Non Surgical Spinal Decompression Using Spinal Decompression Therapy

We have already discussed quite extensively the idea of vertebrate and spinal decompression as a way to increase height, even if it is just temporary. Apparently one of the easiest ways to get our vertebrate/spine decompressed is through Spinal Decompression Therapy. From my own rather superficial research (at this point) of this other way of therapy, the name really says it all. The therapy is to decompress the spine.

Analysis & Interpretation:

I would use three resources to look at the viability and practical usefulness of the idea of using spinal decompression therapy to possibly increase height. The websites from Wikipedia, WebMD, and the website for the American Spinal Decompression Association.

In terms of its medical benefits the spinal decompression therapy is a type of motorized traction that is used to help relieve back pain. The spine is slowly stretched. From the stretching, the amount of force being exerted on the area of the disks is decreased. This means that it might be possible that through the slow decompressed traction any type of bulging or herniated disk will be removed and the disk can go back to it’s less loaded form and heal. The spinal nerves that the herniated or bulging disk that it was touching will no longer be touching anything else which means that the pain trigger is not set off.

The 4 main types of issues that this non-surgical spinal decompression therapy is used to treat include.

  • sciatica
  • bulging/herniated disks
  • spinal joints that have degenerated
  • exposed or degenerated spinal nerve roots

Keep in mind that this type of physical therapy involves having a mechanical device that pulls different parts of the body away from each other. There are many other types of physical therapy which can probably also help with decreasing or alleviating back pain. Besides just the actual device being used to expand the body, the application of other familiar technologies like (electricity) PEMF , (ultrasound) LIPUS, and heat or cold is applied to relieve pain of assist the traction machine.

Overall, the technology is used to treat issues from the neck or lower back. The pulling causes the vertebrate to separate from each other causing a little bit of space between the stretching vertebral areas. The space that is induced will through successive treatments over a 2 month time period is theorized to cause any bulging or herniated disk spinal nerves to be retracted back into the vertebral spine cavity and result in no more nerve touching nerve. From the American Spinal Decompression Association they suggest that the repeated process of intervertebral cavity induction will result in water and nutrients moving from outside the vertebrate inside the spinal column to heal any fractures or holes made from the original decompression.

As for its medical application, the researchers and studies seem to suggest that it is probably more effective in relieving back pain than doing nothing at all. When it is compared to other vertebral/spinal decompression types of therapy, its effectiveness in being better than the others is hard to validate.

Implications For Height Increase:

What we find form the 3 main sources used is that apparently inversion therapy is a type of non-invasive spinal decompression therapy. Inversion therapy is basically using either the gravity boots and hanging upside down on a horizontal bar/pole or using an inversion table. With the inversion table one uses the feet to latch on a segment of the bottom of the table. The table is then swung around 180 degrees so the person is hanging upside down. I have already looked at the idea of the types of devices we can employ in inversion therapy. The posts were “Increase Height Using Gravity Boots” and “Grow Taller Using Inversion Table“. My conclusion is obvious for any of the regular readers of this website but for the first time visitor I will repeat this claim. “The inversion technique or therapy did allow for some height increase. Most people would easily guess that the height increase will be only temporary but what is not well known is that the height increase will actually only be for the time of day when one can reach one’s highest measurement. For most people who sleep the regular hours at night, this means that the effects of the inversion therapy will be noticeable after they wake up, when the are looking at the tallest height measurement of the day. The measured height at the end of the day will still be around the same amount.

As for the more general non-invasive spinal decompression therapy, let’s remember that inversion therapy is a type of non-invasive spinal decompression therapy. The therapy itself get the person to lie down horizontally and has a machine to pull the body. With inversion therapy there is no machine but uses the power of gravity to push down on the body. This could suggest that the therapy might more effectively for heavier set people. This means that the type of one’s body may determine whether the inversion or non-invasive spinal decompresssion therapy might be effective.

As for the overall effectiveness for some height increase, I would say that it is something real to consider.

Spinal Decompression Therapy

If you have lasting back pain and other related symptoms, you know how disruptive to your life it can be. You may be unable to think of little else except finding relief. Some people turn to spinal decompression therapy — either surgical or nonsurgical. Here’s what you need to know to help decide whether it might be right for you.

What Is Nonsurgical Spinal Decompression?

Nonsurgical spinal decompression is a type of motorized traction that may help relieve back pain. Spinal decompression works by gently stretching the spine. That changes the force and position of the spine. This will take pressure off the spinal disks, which are gel-like cushions between the bones in your spine.

Proponents of this treatment say that over time, negative pressure from this therapy may cause bulging or herniated disks to retract. That can take pressure off the nerves and other structures in your spine. This in turn, helps promote movement of water, oxygen, and nutrient-rich fluids into the disks so they can heal.

Doctors have used nonsurgical spinal decompression in an attempt to treat:

  • Back or neck pain or sciatica, which is pain, weakness, or tingling that extends down the leg
  • Bulging or herniated disks or degenerative disk disease
  • Worn spinal joints (called posterior facet syndrome)
  • Injured or diseased spinal nerve roots (called radiculopathy)

More research is needed to establish the safety and effectiveness of nonsurgical spinal decompression. To know how effective it really is, researchers need to compare spinal decompression with other less expensive alternatives to surgery. These include:

  • Nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Physical therapy
  • Exercise
  • Limited rest
  • Steroid injections
  • Bracing

How Is Nonsurgical Spinal Decompression Done?

You are fully clothed during spinal decompression therapy. The doctor fits you with a harness around your pelvis and another around your trunk. You either lie face down or face up on a computer-controlled table. A doctor operates the computer, customizing treatment to your specific needs.

Treatment may last 30 to 45 minutes and you may require 20 to 28 treatments over five to seven weeks. Before or after therapy, you may have other types of treatment, such as:

  • Electrical stimulation (electric current that causes certain muscles to contract)
  • Ultrasound (the use of sound waves to generate heat and promote healing)
  • Heat or cold therapy

Who Should not Have Nonsurgical Spinal Decompression?

Ask your doctor whether or not you are a good candidate for nonsurgical spinal decompression. It is best not to try it if you are pregnant. People with any of these conditions should also not have nonsurgical spinal decompression:

  • Fracture
  • Tumor
  • Abdominal aortic aneurysm
  • Advanced osteoporosis
  • Metal implants in the spine

Non Surgical Spinal Decompression

Non-Surgical Spinal Decompression is a revolutionary new technology used primarily to treat disc injuries in the neck and in the low back. This treatment option is very safe and utilizes FDA cleared equipment to apply distraction forces to spinal structures in a precise and graduated manner. Distraction is offset by cycles of partial relaxation. This technique of spinal decompression therapy, that is, unloading due to distraction and positioning, has shown the ability to gently separate the vertebrae from each other, creating a vacuum inside the discs that we are targeting. This “vacuum effect” is also known as negative intra-discal pressure.

The negative pressure may induce the retraction of the herniated or bulging disc into the inside of the disc, and off the nerve root, thecal sac, or both. It happens only microscopically each time, but cumulatively, over four to six weeks, the results are quite dramatic.

The cycles of decompression and partial relaxation, over a series of visits, promote the diffusion of water, oxygen, and nutrient-rich fluids from the outside of the discs to the inside. These nutrients enable the torn and degenerated disc fibers to begin to heal.

For the low back, the patient lies comfortably on his/her back or stomach on the decompression table, with a set of nicely padded straps snug around the waist and another set around the lower chest. For the neck, the patient lies comfortably on his/her back with a pair of soft rubber pads behind the neck. Many patients enjoy the treatment, as it is usually quite comfortable and well tolerated.

Non-Surgical Spinal Decompression is very effective at treating bulging discs, herniated discs, pinched nerves, sciatica, radiating arm pain, degenerative disc disease, leg pain, and facet syndromes. Proper patient screening is imperative and only the best candidates are accepted for care. Please go to the “Find a Physician” link to find a doctor in your area.

From the Wikipedia article on Spinal Decompression

Spinal decompression is a term that describes the relief of pressure on one or many pinched nerves (neural impingement) of the spinal column.[1]

Spinal decompression can be achieved both surgically and non-surgically and is used to treat conditions that result in chronic back pain such as disc bulge, disc herniation, sciatica, spinal stenosis, and isthmic and degenerative spondylolisthesis.

Surgical spinal decompression may be performed using one of these common procedures:

Surgical spinal decompression

Microdiscectomy (or microdecompression) is a minimally invasive surgical procedure in which a portion of a herniated nucleus pulposus is removed by way of a surgical instrument or laser while using an operating microscope or loupe for magnification.[2]

Laminectomy (or open decompression) is an invasive surgical procedure in which a small portion of the arch of the vertebrae (bone) is removed from the spine to alleviate the pressure on the pinched nerve. This is an elective procedure for patients who have not had relief of back pain through more conservative treatment options.[3]

Non-surgical spinal decompression

In nonsurgical spinal decompression, a patient is strapped securely to a table. Mechanical traction slowly and temporarily alleviates spinal pressure.

Non-surgical spinal decompression is achieved through the use of a mechanical traction device applied through an on-board computer that controls the force and angle of disc distraction, which reduces the body’s natural propensity to resist external force and/or generate muscle spasm. This enhanced control allows non-surgical spinal decompression tables to apply a traction force to the discs of the spinal column reducing intradiscal pressure, unlike previous non-computer controlled traction tables.

Inversion therapy, which involves hanging upside down, is a form of mechanical traction used for spinal decompression.[4]

The practice is promoted as safe and effective without the normal risks associated with invasive procedures such as injections, anesthesia or surgery. Spinal decompression works through a series of 15 one minute alternating decompression (using a logarithmic decompression curve) and relaxation cycles with a total treatment time of 30 minutes. During the decompression [5] phase the pressure in the disc is reduced and a vacuum type of effect is produced on the nucleus pulposis. At the same time nutrition is diffused into the disc allowing the annulus fibrosis to heal. Very rarely is the nerve root compressed from the herniated disc and usually the back and leg pain associated with these conditions is a result of irritation to the nerve root sleeve by the inflammatory chemicals that are released as a result of inflammation in the disc.[6]

For the low back, the patient lies comfortably on his/her back or stomach on the decompression table, with a set of nicely padded straps snug around the waist and another set around the lower chest. For the neck, the patient lies comfortably on his/her back with a pair of soft rubber pads behind the neck. Many patients enjoy the treatment, as it is usually quite comfortable and well tolerated.[7]

The treatment has several varying versions, including articulating spinal decompression or range-of-motion (ROM) decompression, which enables the doctor or therapist to adjust the patient’s spinal posture during the decompression. Varying the spine’s posture enables the decompressive pulling forces to reach into spinal areas and tissues that basic linear decompression misses. The Antalgic-Trak is a brand name for an articulating decompression system.[8]

Theoretical foundations

The theory behind non-surgical spinal decompression is that significant distractive forces, when applied to the lumbar spine in variable directions, can create a negative pressure in the center of the intervertebral disc, thereby creating a suctioning effect or vacuum phenomenon in order to retract or reduce the size of the herniated or bulging disc’s gelatinous internal nucleus pulposus, thus diminishing or eliminating nerve compression, while at the same time creating an osmotic gradient which helps bring nutrients and water into the disc. Since intervertebral discs have poor circulation, they depend upon receiving their nutrition through diffusion across the end plates of the vertebrae above and below.

The appeal of non-surgical spinal decompression is that it is a non-invasive, non-surgical, drug-free alternative treatment for low back pain, sciatica, disc degeneration, disc bulges, disc herniations, and facet syndrome. There is copious anecdotal evidence of its effectiveness and more case studies are being published demonstrating very positive results in patients who have tried other conservative treatments that have failed.

History

Non-surgical spinal decompression was originally developed and pioneered by Dr. Allan Dyer, PhD, MD in 1985 and the first non-surgical spinal decompression table, the Vax-D was introduced by him in 1991.[9] This original device was controlled by a pneumatic system and gradually applied and released, with the traction force being applied to reduce muscle guarding and spasm. In 2004, Vax-D Medical Technologies introduced an enhanced version of this table called the G2 that replaced the pneumatic technology with more precise electrically driven components and also added an enhanced on board computer control system that instituted a logarithmic curve.[10]

Many other doctors, scientists, and corporations have developed other non-surgical spinal decompression tables, each with features believed to mimic or enhance the effectiveness of the original concept. Intervertebral differential dynamics (IDD) therapy[11] is a similar technique.

Effectiveness

In a small randomized study of 44 subjects, in which one author disclosed a proprietary interest in Vax-D, it was shown to have a clinical success rate of 68.4%.[12]

A 2004 report by the State of Washington Department of Labor and Industries concluded “Published literature has not substantially shown whether powered traction devices are more effective than other forms of traction, other conservative treatments, or surgery.”[13] A 2005 review of VAX-D (including the Sherry study above) by the Workers’ Compensation Board of British Columbia concluded “To date there is no evidence that the VAX-D system is effective in treating chronic LBP associated with herniated disc, degenerative disc, posterior facet syndrome, sciatica or radiculopathy.”[14]

A 2006 systematic review of studies of spinal decompression using motorized traction devices conducted between 1975 and October 2005 (including the two mentioned above) concluded that “…the efficacy of spinal decompression achieved with motorized traction for chronic discogenic low back pain [remained] unproved”, and called for “Scientifically more rigorous studies with better randomization, control groups, and standardized outcome measures … to overcome the limitations of past studies.”[15] A technology assessment conducted in 2007 by the Agency for Healthcare Research and Quality (for which the two studies cited above were included for analysis) said “Currently available evidence is too limited in quality and quantity to allow for the formulation of evidence-based conclusions regarding the efficacy of decompression therapy as a therapy for chronic back pain when compared with other non-surgical treatment options.”[16]

A 2007 critique of research studies, including the two cited above, said:

There is very limited evidence in the scientific literature to support the effectiveness of non-surgical spinal decompression therapy. This intervention has never been compared to exercise, spinal manipulation, standard medical care or other less expensive conservative treatment options which have an ample body of research demonstrating efficacy. Considering the cost-benefit relationship, many better researched and less expensive treatment options are available to the clinician.[17]
