Effects of the Nintendo Wii training on balance rehabilitation and quality of life of patients with Parkinson's disease: A systematic review and meta-analysis.

BACKGROUND: Randomized clinical trials (RCTs) used the Nintendo Wii (NW) in the treatment of Parkinson Disease, however, no meta-analysis was developed to determine the effects in these patients. OBJECTIVE: To analyze RCTs that investigated the effects of NW versus traditional physiotherapy on balance rehabilitation and quality of life of patients with PD. METHODS: Electronic research was conducted between December 2018 and January 2019 in the MEDLINE, PEDro, CEN-TRAL, LILACS and SciELO databases. The methodological quality was evaluated by the PEDro scale and the completeness of the description of the interventions by the TIDieR checklist. Weighted mean differences (WMD) and 95% confidence interval (CI) were calculated. RESULTS: Five studies were included and presented an average of 5.4 (1.5) on the PEDro scale and 6.7 (1.4) on the TIDieR. Compared to traditional physiotherapy, combined NW and traditional physiotherapy resulted in improvement in balance WMD 1.24 (95% CI: CI: 0.2 to 2.3 N = 72) and quality of life WMD-8.9 (95% CI:-15.2 to-2.6 N = 56). CONCLUSION: combined NW and traditional physiotherapy was more effective on balance rehabilitation and quality of life of patients with PD, but the values demonstrated a poor methodological quality and a low level of completeness of the intervention descriptions.
