OBJECTIVE: To assess the effectiveness of Wii sports-based strategy training on risk of falling, falls and quality of life in adults with idiopathic Parkinson's disease. DESIGN: Single blind, randomised comparative trial. SETTING: Hospital and home. SUBJECTS: Diagnosed as idiopathic Parkinson's disease, Hoehn-Yahr stage 2.5 to 4, history of at least 3 falls in the last 3 months. INTERVENTION: Experimental group participated in 30 to 40 min of Wii training, 3 session/week for 12 weeks and control group participated for the same duration in traditional balance training. During each session both the group received 30 min of conventional physiotherapy. OUTCOMES: Number of fallers, Fall rate, Berg balance scale, Timed up and go test, Parkinson's disease questionnaire 39, at baseline, 12th and 36th week after baseline. RESULTS: We randomised 192 participants. Participant 's characteristics were similar between Wii and control group at base line, in age 69.7 +/- 10, 68.5 +/- 9.8, disease severity 3.43 +/- 0.56, 3.42 +/- 0.59, and fall rate 10.47 +/- 15.78, 11.80 +/- 18.95 (in mean +/- SD). At 12th week 28% (27), 51% (49) & 36th week 45% (42), 60% (57) in Wii-group, control group fell at least once, respectively. Wii group improved more than control group at 12th, 36th week in number of fallers (-23%, p < 0.001) (-15%, p < 0.039), fall rates -2.635 (-5.38 to 0.112), -1.476 (-5.09 to 2.142) (difference in mean, Confidence Interval) and bodily discomfort component of PDQ 39. CONCLUSION: A 12 weeks exercise training using the Wii sports-based strategy decreases the number of fallers, fall rate, measures of risk of falling but did not alter the quality of life in adults with idiopathic Parkinson's disease.
