ObjectiveTo investigate the effects of a training program based on virtual reality on static and dynamic balance performance in patients with Parkinson's disease (PD). MethodsFrom June, 2014 to June, 2016, 46 patients with PD were randomly divided into control group (n=23) and experimental group (n=23). The control group received routine balance training, while the experimental group received balance training of virtual reality, for six weeks. They were assessed with Unified Parkinson's Disease Rating Scale part 3 (UPDRS3), Berg Balance Scale (BBS), Timed "Up and Go" Test (TUGT) and Hamilton Depression Scale (HAMD) before and after training. The envelope area, anteroposterior standard deviation (AP-SD), mediolateral standard deviation (ML-SD) of centre of pressure (COP) were also measured with posturography. ResultsThe scores of BBS, TUGT and HAMD improved in both groups after training (t>2.657, P<0.05), and improved more in the experimental group than in the control group (t>2.426, P<0.05). The score of UPDRS3 and the parameters of posturography improved in the experimental group (t>2.626, P<0.05), and improved more than that in the control group (t>2.112, P<0.05). ConclusionVirtual reality rehabilitation is more effective than routine balance training on the static and dynamic balance function in patients with PD, and may release their depression.
