Effect of whole body vibration in Parkinson's disease: a controlled study

[Abstract] In the search of new strategies to improve the quality of life of Parkinson's disease patients, recent work has reported an amelioration of Parkinsonian symptoms using Whole Body Vibration (WBV). A double-blinded, placebo controlled design was used to evaluate the effect of a 12 WBV sessions-programme on a number of motor and clinical tests in 23 Parkinson's disease patients. Patients were assigned to one of two groups, one receiving WBV and the other a placebo group. At the end of the programme as well as during intra-session evaluation, there was no difference between the experimental (vibration) and placebo groups in any outcomes. These results suggest that reported benefits of vibration are due to a placebo response.Galicia. Consellería de Educación; 2007/000140-0Galicia.
