Abstract
Objective The aim of this study was to analyze the effects of a rehabilitation program with whole body vibration on static and functional balance in chronic stroke patients. Material and methods Twenty-two patients participated. They were divided into two groups: experimental group (EG, n = 11), who received 17 sessions of vibration over 8 weeks and control group (CG, n = 11) who received the same 17 sessions on the platform in the same position as the EG but did not receive vibrations. Balance was assessed before and after intervention using the Romberg test, the Tinetti's test and the Berg balance scale. Results Changes were not observed after the intervention with the Romberg and Tinetti's tests. However, the Tinetti's test showed a tendency to improve in the EG. Regarding the Berg's scale, persons with hemiparesis on the left side improved after the intervention ( P<.01), but not those with hemiparesis on the right side ( P=.420). Conclusions The whole body vibration improves functional balance in patients who have suffered a stroke. Although these improvements are similar to those found in isometric exercise when not complemented with vibration, it seems that the vibrations could induce greater benefits in certain assessments of balance. Isometric work in semi-squat position improves balance function in patients who have suffered a stroke. The application of whole-body vibration during isometric work this could be beneficial in some evaluations of balance. Patients with left-sided hemiparesis seem to benefit more from balance rehabilitation programs.
