Input: We included 10 trials, of which six focused on Parkinson's disease and four on multiple sclerosis. None of the studies reported data on the primary outcome (functional performance). In Parkinson's disease, after pooling two studies, a single session of WBV caused a significant improvement of gait measured using the Timed Up and Go test (TUG) in comparison to standing exercises (mean difference -3.09, 95% confidence interval -5.60 to -0.59; P = 0.02; I2 = 0%). Nevertheless, longer duration of WBV did not show significant results in comparison with physical therapy in body balance or signs and symptoms measured with the Unified Parkinson's Disease Rating Scale (UPDRS). In multiple sclerosis there was no evidence of a short-term or long-term effect of WBV on body balance, gait, muscle performance or quality of life. Adverse events were reported in few trials. In those trials that reported them, the intervention appeared to be safe. There is insufficient evidence of the effect of WBV training on functional performance of neurodegenerative disease patients. Also, there is insufficient evidence regarding its beneficial effects on signs and symptoms of the disease, body balance, gait, muscle strength and quality of life compared to other active physical therapy or passive interventions in Parkinson's disease or multiple sclerosis. More studies assessing other functional tests and accurately assessing safety are needed before a definitive recommendation is established.
Output:

Exercise training using vibratory platform (whole body vibration) has been recently introduced as a complementary treatment to rehabilitation.This review identified ten trials performing whole body vibration (WBV) in neurodegenerative diseases: six in Parkinson's disease and four in multiple sclerosis. Diversity in treatments and outcomes measures makes difficult to quantitatively compare the effect of WBV intervention across studies and to assess its efficacy. There is insufficient evidence to determine the potential benefits of WBV training in functional performance according to activities of daily life, body balance, signs and symptoms of disease, muscle performance, and quality of life in patients with neurodegenerative diseases. Adverse events were poorly reported in the included studies, but this kind of training seems to be a safe intervention. These conclusions are based on a small number of studies with a limited methodological quality.
