Objective To explore the effects of somatosensory game rehabilitation exercise on the frailty level and balance ability in community-dwelling pre-frail older adults. Methods From June to September 2022, a total of 46 community-dwelling pre-frail older adults from four communities of Guiyang city were selected conveniently and randomized into a control group and an intervention group, with 23 cases in each group. The control group maintained their daily exercise and received health education, while the intervention group additionally received somatosensory game rehabilitation exercise intervention for 12 weeks, three times per week. The frailty level and balance ability of the two groups were assessed before the intervention and at the end of the 12-weeks intervention. Results There were 2 dropouts in the intervention group. At the end of the 12-weeks intervention, the frailty score in the intervention group was significantly lower than that of the control group, and the static balance ability, dynamic balance ability, reactive balance ability, and comprehensive balance ability in the intervention group were significantly better than those of the control group (all P<0.05). Conclusion Somatosensory game rehabilitation exercise can alleviate the frailty level of community-dwelling pre-frail older adults, and improve their balance ability.
