Has any physical therapist heard about the new technology called "vibration exercise?"

Torvinen S, Sievanen H, Jarvinen TA, Pasanen M, Kontulainen S, Kannus P. Effect of 4-min Vertical Whole Body Vibration on Muscle Performance and Body Balance: A Randomized Cross-over Study. Int J Sports Med 2002 Jul;23(5):374-9
This study was a (the only, actually) randomized cross-over study was to investigate the effects of a 4-min long, 2-mm vertically-vibrating vibration-exercise on muscle performance and body balance in healthy subjects.
Sixteen volunteers (eight men and women aged 18-35 years) underwent both the 4-min vibration- and sham-interventions in a randomized order on different days.
Performance- and balance-tests (stability platform, grip strength, extension strength of lower extremities, tandem-walk, vertical jump and shuttle-run) were done 10 minutes before (baseline) and 2 and 60 minutes after the intervention. In addition, the effect of vibration on the surface electromyography (EMG) of soleus, vastus lateralis, gluteus medius, and paravertebralis muscles was investigated during the vibration.
The 4-min vibration-loading did not induce any statistically significant change in the performance- or balance-tests at the 2- or 60-min tests.
Interestingly, however, the mean power frequency of the EMG in the vastus lateralis and gluteus medius muscles decreased during the vibration-intervention, indicating muscle fatigue, particularly in the hip region. It was concluded that a 4-min long, 2-mm vertically-vibrating vibration-stimulus did not induce changes in the performance and balance tests.
Future studies should focus on evaluating the effects of different kinds of vibration-regimens, as well as the long-term effects of vibration-training, on body balance and muscle performance, and, as a broader objective, on bone.

You suggest that there is no benifit to vibration therapy which to me seems logical. What I'm having a tough time understaning is what was the rationale behind such treatments?

I originally posted the question on "vibration exercise" to get a handle on the awareness of this treatment technology. Would you believe it has been around since the late 1800's (in Europe)? I recently met and spoke with the author of the following abstract presented at the 2001 AAPM&R meeting. Check it out and if interested, I can provide additional information on the technology.

Disclosure: None.
Objective: To explore (1) the efficacy of whole body vibration (WBV) in inducing reflex standing and, specifically, (2) the progress of persons with spinal cord dysfunction of 3 differing etiologies. Design: Case series. Setting: Rehabilitation center in a metropolitan area. Patients: Persons with spinal paralysis of various etiology who were otherwise unable to stand without the use of long-leg braces locked at the knee. Case 1: a 21-year- old man who underwent laminectomy at T2–9 for resection of an intramedullary tumor. Case 2: a 12-year-old boy presented with quadriplegia secondary to transverse myelitis. Case 3: a 24-year-old man with C5 American Spinal Injury Association class A tetraplegia for 5 years secondary to a fall. Interventions: WBV to produce rapid, mechanically delivered repetitive stretches to the lower extremities, thereby resulting in involuntary muscle contraction. Main Outcome Measures: Standing time with and without WBV, degree of volitional movement, trunk, and body control, ability to transfer, and carry over to voluntary standing and walking. Results: All 3 patients were able to stand with minimal assistance and to increase progressively the length of standing time. Eventually, 2 were able to walk independently using various ambulatory aids. Conclusions: WBV represents a promising modality for use in the rehabilitation of persons with motor dysfunction of spinal origin. In our sample, WBV successfully induced reflex standing in all 3 patients and standing was followed by ambulation in 2 cases. Key Words: Rehabilitation; Spinal cord dysfunction; Motor function.

There was a study from Spine (1st issue in september) looking at whole body vibration versus something else (can't remember), and it didn't show a significant difference in terms of pain relief and functional gain. I read through the things that the machine was suppose to do... stretch muscles, activate muscles and even lose weight (that must a commercial thing rather than scientific)! I stood on one of these machines the other day and felt the shock go all the way up my back. The non-specific nature of the vibrations make me think how is this different to doing mobilisations on every joint of the body?

Henry,
What you most likely stepped on was a machine called the Power Plate, a "rip-off" of the patented product. You are correct in that there is NO specific pattern to the vibtration with this product. I urge all of you interested to view the Galileo 2000 at the website of OrthoMetrix, Inc. It is [URL=http://www.orthometrix.net]www.orthometrix.net[/URL] and the Galileo 2000 has been approved by the FDA for osteoporosis, incontinence, diabetes, parkinsons and a few others. You will all be hearing more about this technology, in the coming year. Do NOT confuse the original Galileo 2000 with the knock-off product, the Power Plate.
Thanks

Here is my abstract on the article from Spine
TREATMENT OF CHRONIC LOWER BACK PAIN WITH LUMBAR EXTENSION AND WHOLE-BODY VIBRATION EXERCISE: A RANDOMIZED CONTROLLED TRIAL. Spine, Vol. 27, No. 17, September 1, 2002.
Jorn Rittweger, MD Karsten Just MD et al
ABSTRACT
Whole body exercise, or VbX, is a new form of exercise being tested in sports, geriatrics, and rehabilitation. Recently, it has been shown that metabolic power increases during whole-body vibration, and that this increase is further enhanced with the addition of loads to the shoulders, which suggests an enhanced activity of the trunk muscles. These authors believed that VbX could elicit the trunk muscle stretch reflexes and therefore be a means of activating and strengthening these muscles. Also, as pain is determined by peripheral nociception and central pain sensitivity, activating this type of system could also result in reduced pain.
Two groups of 25 persons, randomly placed, were used for this study. There were 19 smokers and 41 non-smokers, mean age was 51.7 years, and the mean length of chronic low back pain was 13.1 years. Subjects were found via a newspaper ad looking for individuals with chronic low back pain with no underlying disease, either for more than 6 months or intermittently for more than 2 years. Exclusion criteria included pregnancy, lumbar disc problems, metal implants, and osteoporosis. The Allgemeine Depressions Skala (ADS) was used to screen out any significant depression situations. One group performed the VbX, while another performed back extensor strengthening on an LE-Mark1 (MedX).
Prior to the initiation of training, two trials were performed to determine lumbar extension torque, while pain was assessed via a VAS scale, and pain related limitations in every day life was assessed with the PDI (Pain Disability Index). Subjects then underwent training for 2 units per week for the first 6 weeks, and 1 unit per week for each week thereafter.
LEX training was performed with the addition of abdominal curl-ups and leg presses. The VbX training took place on a Galileo 2000, which consists of a platform that oscillates around a resting axis between the subject’s feet. Foot distance determines the amplitude of the oscillations, and the maximum amplitude used was 6mm. The subjects performed slow movements of the hips and waist, with flexion in the saggital and frontal planes, and rotation in the horizontal plane. Progression in the program was accomplished by adding weights up to 5kg to the shoulders.
Results indicate that isometric lumbar torque increased in the LEX group by 59.2kg and the VbX group by 30.1kg. 7 participants in the LEX group had increases in overall lumbar ROM, while 3 did in the VbX group, but the differences between the groups was not considered significant. Both groups reported a significant decrease in pain sensations, with the LEX group dropping from 4.52 to 1.2 on the last visit, and the VbX group going from 4.16 to 1.4. Pain related disability index dropped significantly for each group at the end of the treatment and maintained the position at the 6-month follow-up. With regards to tendency to depression, there were reduced values in the LEX group at the conclusion of treatment and again at 6 months, but these values did not change for the VbX group.
Whole body vibration exercise appears to be a helpful treatment in nonspecific chronic low back pain and yields almost the same results as a lumbar extension exercise program. Spatial requirements favor the VbX, which takes up 3 sq/m vs. the LEX machine, which take up 12 sq/m.

bharvey,
It was the Gallileo 2000 that I had a go on, and I read the things that it was suppose to do. Weight loss was definitely one of them. I would be careful because this sounds like another fad that, if there is no sufficient evidence and specificity, will go out the door like many electrotherapy machines (this is my opinion anyway)

Anyone who is skeptical, I would be happy to send a bibliography. Just get me your email. My sense is that this type of therapy is similar to isokinetics in the late 60s, early 70s. It is true that many are unaware of the docummentation to support this training device.
