Because hand and cognitive functions decline in the elderly, intervention programs addressing these problems are necessary. In recent years, creating rehabilitation programs using technology has gained popularity. The aim of this study is to examine the effects of technology-based rehabilitation using LMC (Light Mood Enhancer) and dual upper extremity tasks on joint position sense, grip strength, functionality, and executive functions in elderly individuals; and to compare these effects with those of an exercise program performed solely with an LMC device and a control group consisting of a hand rehabilitation program performed with a physiotherapist. The research is a randomized controlled trial and will consist of 3 groups. After randomization, individuals' joint position sense, gross and fine grip strength, functionality, and executive functions will be evaluated. Evaluations will be performed twice, at the beginning and end of the 8-week program.
