Whole body vibration therapy, a revolutionary technique that efficiently treats Parkinson's disease

A novel non-traditional physical therapy method is available for advanced Parkinson's disease (PD) patients that do not respond well to medications such as L-dopamine. Scientists from the Sun Life Financial Movement Disorders Research and Rehabilitation Centre from Ontario, Canada have shown that short term whole body vibration therapy significantly improves the clinical symptoms (loss of gait, tremors and akinesia) of PD patients. In this clinical study, a sample population of 40 PD patients were subject to intensive therapy for a few weeks using a Physioacoustic Chair, an sophisticated device containing speakers that are strategically placed throughout the chair in order to deliver programmed low frequency sound waves throughout the body of the patient.
This study is remarkable in the sense that acoustic therapy had a significant impact on the well being and quality of life of PD patients. In brief, the Unified Parkinson's Disease Rating Scale (UPDRS), gait assessments and upper limb control tests showed significant improvements on gait stability and posture, increased stepping time and speed on the peg-board task, a significant decrease in tremors and less rigidity in PD patients receiving whole body vibration therapy compared to a control group that received no therapy. More importantly, this study showed that whole body vibration therapy may also be applied to PD patients that do not respond well to L-dopamine medication or deep brain stimulation, a complicated risky surgery that involves delivering mild electrical shocks to the brain via implanted electrodes. The latter technique is used as a last resort to stabilize tremors and rigidity in PD patients.

Whole body acoustic stimulation vs. conventional physical therapy for treating PD

Before this study, another previous study conducted about a year ago showed that whole vibration therapy is even more effective in reversing many of the clinical symptoms of PD patients compared to conventional physical therapy. Specifically, this particular study showed that whole body vibration therapy improved equilibrium and gait four weeks after undergoing an intensive three week regimen consisting of 15 minutes a day for five days a week.
Remarkably, this study quantitatively also suggests that whole body vibration therapy is more efficient (25% more efficient) than conventional physical therapy for partially reversing clinical symptoms in PD patients that do not respond well to L-dopamine. It will be interesting to know whether a combined therapy that uses both whole body and conventional intervention techniques has an additive/ synergistic positive effect in reversing clinical PD symptoms compared to single treatment intervention.

Brief background on whole body vibration therapy.

The technology used for conventional physical therapeutic interventions of PD patients have included the use of treadmills, different optical and acoustic devices, balance/ gait training devices and low impact exercise machines. On the other hand, the concept and practice of whole body vibration therapy is not novel since this technique has been used by athletes as part of a routine exercise to loose weight, improve muscle tone and increase muscle strength.
Whole body vibration therapy was initially postulated and developed by Jean Martin Charcot, who also developed a vibration chair many decades ago! There are currently a few devices currently in the market that have been tweaked and redesigned with from other existing prototypes. Some of the most well known whole body vibrational devices are sold by Galileo Fitness and is used for many applications including relaxation therapy, strength training and muscle toning, and for physical therapy. The machine looks like a typical workout machine with arm rests, a bottom platform, and a console that allows a user to program a variety of amplitude and frequency settings (18-28 Hz). Once a patient stands on top of the platform and grabs the arm rests, he/she may receive a short session of either low frequency sound waves that allow for muscle relaxation while higher amplitude and frequency settings is used for increasing muscle tone and contraction.
Whole body vibration therapy has also been used in the past to treat patients affected by neuromuscular debilitating and neurodegenerative disorders such as multiple sclerosis, stroke, cerebral palsy, Huntington's chorea, and other movement disorders. It is not known how whole body acoustic therapy works in Parkinson's disease patients but it is believed that high vibrational frequencies help to partially restore some of the sensory perception (proprioception) that is lost during the progression of the disease and is also used to enhance muscle coordination, a physical trait that is lost during the progression of PD. Finally, high frequency sound waves delivered via physicoacoustic devices has been shown to improve blood flow, electrical conductivity and metabolism of muscle tissue.

  1. As described in this article has many Parkinson's symptoms such as pain which can be alleviated with the purchase online vicodin is a drug that can be purchased without a prescription but must be very careful with side effects such as anxiety and is taken for a long time addiction.

  3. Alternatively, have you ever been in a bad mood, and the presence of a happy and optimistic person makes that bad mood not so bad? Maybe it's possible to be "sensitive" to the brain waves of others, or to have strong brain waves that can affect other people.

  4. My husband was diagnosed with early onset Parkinson's disease at 57.his symptoms were shuffling of feet,slurred speech, low volume speech, degradation of hand writing, horrible driving skills, right arm held at 45 degree angle, things were tough for me, but now he finally free from the disease with the help of total cure ultimate health home, he now walks properly and all symptoms has reversed, he had trouble with balance especially at night, getting into the shower and exiting it is difficult,getting into bed is also another thing he finds impossible.we had to find a better solution for his condition which has really helped him a lot,the biggest helped we had was ultimatehealthhome they walked us through the proper steps,am highly recommended this ultimatehealthhome@gmail.com to anyone who needs help.
