Whole Body Vibration Induces Back Pain
Despite the mounting evidence of efficacy for low frequency vibration therapy as a treatment for back conditions and joint conditions, as well as for multiple sclerosis and other disease, there is also some evidence that repeated whole body vibration can be harmful. Looking at farmers who experience chronic whole body vibration through their workplace activities, such as when operating farm vehicles, reveals a dose-response relationship between exposure to whole body vibration and low back pain, together with other factors such as age, body posture, and accidents involving the spine (Solecki, 2011).
Whole Body Vibration Therapy for Chronic Low Back Pain
Researchers in Spain meanwhile have been looking at the use of whole body vibration therapy, using low frequencies, to reduce the severity of chronic non-specific low back pain. Such symptoms make it unlikely that back surgery will be offered as a treatment as the cause of the pain cannot be isolated; spinal stenosis, whilst present, may not itself be responsible for the symptoms of back pain. del Pozo-Cruz, et al (2011), took fifty patients and applied whole body vibration therapy to half the group, using the other twenty-five patients as a control. After twelve weeks of vibration therapy, with twenty-four training sessions there was a statistically significant improvement in postural stability, back pain, and strength according to various well-established assessment methods. Postural Stability index scores improved more than 20% in the vibration therapy group, with a 24.13% improvement on the visual analogue scale for back pain. The authors noted that the use of vibration plate therapy for those with non-specific chronic low back pain could be a novel therapy, with the potential to reduce reliance on pain medications and the desire for back surgery for spinal stenosis.
