The experimental group(n=14) participated in the occupational therapy using the music-based cognitive stimulation digital device program. And, the control group(n=12) participated in a program offered by a welfare center. To analyze the impact of an intervention program, cognitive, depression, and hand function were pre- and post-tested. Results : For the experimental group, the 3.36 points of total score was improved, but, for the control group, 0.39 points was decreased, which indicates that the occupational therapy using the music-based cognitive digital device program affect the positive improvement on the cognitive function. And, the program improved depression and hand function significantly. Conclusion : The occupational therapy using the music-based cognitive stimulation digital device program have positive influence on the improvement of cognitive function, depression and hand function of elderly aged 65 or older.
