Aging impacts musculoskeletal function declines, such as joint stiffness and muscle pain, which can trigger geriatric emergencies like falls and immobilization. This study aimed to determine the effectiveness of stretching-based group activity therapy in reducing pain and improving mortality in the elderly. The design used was a quasi-experimental pre-test and post-test without a control group, involving 47 elderly at the Pelayanan Sosial Tresna Werdha Magetan (Healthcare and Rehabilitation Unit). The intervention was conducted in one 40-minute, consisting of statistical and dynamic stretching of several body parts. Evaluation was conducted using a Visual Analog Scale. Results showed a significant reduction in pain (median Visual Analog Scale from 6–8 to 2–3) and active participation by all participants. The discussion confirmed that group activity therapy stretching is effective as a non-pharmacological intervention for preventing chronic pain and the risk of musculoskeletal emergencies in the elderly, and provides psychosocial benefits through group interaction.
