Effects of communal exercise with visual and auditory feedback provided by a smart application on gait ability and fear of falling in Parkinson’s disease patients

Parkinson’s disease is a chronically developing neurodegenerative disease showing typical motor symptoms of the following triad: resting tremor, freezing of gait, and bradykinesia-hypokinesia. In the present study, we investigated the effects of a communal exercise program, using the visual and auditory feedback provided by a smart application, to assess gait ability, fear of falling, and fall efficacy in Parkinson’s disease patients. Subjects consisted of 29 Parkinson’s disease patients who were non-demented individuals. The subjects were randomly divided into three groups: the control group (n= 9, CG), the communal exercise group using the smart application (n= 10, CCEG), and the individual exercise group using the smart application (n= 10, ICEG). The communal exercise program consisted of a warm up (10 min) followed by communal exercise using the smart application (40 min), and a cool down (10 min) for 3 days per week over 10 weeks. The results presented here show that velocity and cadence were significantly increased among groups. Step and stride length were significantly increased among times. Fear of falling and fall efficacy were significantly different among groups and times. In particular, fear of falling was lower and fall efficacy was higher in the CCEG than in the ICEG and CG. These findings indicate that 10 weeks of the communal exercise program using the smart application can be effective in improving gait ability, fear of falling, and fall efficacy in Parkinson’s disease patients.
