This study was conducted to investigate what effects therapeutic music activities have on feeling conditions and helplessness of the Elderly with mild cognitive impairment. This study implemented preliminary and post control group design from April 1 to May 10, 2013. It was conducted twice a week, 50 minutes a session, and total 12 times for 6 weeks. The subjects of the study were as followed: 8 aged people with mild cognitive impairment who use day care center for the elderly in G district were selected to be an experimental group, and another 8 old people with mild cognitive impairment from D district became a control group. What changes there were in feeling conditions and helplessness of the subjects before and after music therapy were analyzed. The results of the study are following: first, in the change of feeling conditions, the experimental group which conducted therapeutic music activities was statistically significant, as its preliminary-post feeling condition scores were more reduced than that of control group which did not have therapeutic music activities. Second, in the change of helplessness, the experimental group which had therapeutic music activities was statistically significant as its preliminary-post helplessness scores were more reduced than that of control group which did not perform therapeutic music activities. Third, it was proved that, between scores of feeling conditions and helplessness, as feeling condition is improved, helplessness is reduced, so they have statistically significant positive correlation. Therefore, it is considered that therapeutic music activity improves feeling conditions and reduces helplessness of the elderly with mild cognitive impairment, so it can be a useful therapeutic method that enhances quality of life.
