This study aims to evaluate the effectiveness of a combination of massage therapy and heat therapy on improving joint range of motion in patients with shoulder pain. Shoulder pain is often accompanied by limited range of motion, which can affect daily activities and quality of life. Massage therapy is known to relieve muscle tension and improve blood circulation, while heat therapy has the effect of reducing muscle stiffness and increasing tissue elasticity. The combination of these two therapies is expected to provide synergistic benefits in overcoming shoulder pain problems and improving joint range of motion. This research method is pre-experimental with a one group pretest and posttest design approach. The study involved giving a combination of masage therapy and heat therapy regularly to a group of patients with shoulder pain. Joint range of motion was evaluated before and after the intervention using a pretest-posttest design. Statistical analysis, including t-test and significance test, was used to assess the difference between the mean pretest and posttest. The results showed a significant increase in the mean posttest compared to the pretest. The results of the significance test also showed that the effect that occurred was significant (0.001 <0.05), indicating the effectiveness of the combination of massage therapy and heat therapy in increasing joint range of motion in patients with shoulder pain.These findings provide strong support for the implementation of a combination of massage therapy and heat therapy as an effective approach in shoulder pain rehabilitation by improving joint range of motion limitations. This study contributes to the scientific understanding of the synergistic benefits of both therapies and provides a basis for the development of improved treatment guidelines for individuals with similar conditions.
