The Shoulder Pain and Disability Index (SPADI) is a measurement tool designed to evaluate the level of pain and functional limitations in patients with shoulder complaints. It consists of two main subscales, namely pain scale and disability scale, both of which are very important in measuring the effectiveness of therapeutic interventions in shoulder pain conditions. On the other hand, INMAS (Integrated Neuromuscular Acupuncture System) electropuncture therapy is a non-pharmacological intervention that uses electrical stimulation at acupuncture points to relieve pain. It combines acupuncture principles with neuromuscular stimulation targeted at the muscles and soft tissues around the shoulder. INMAS electropuncture works by improving blood circulation, reducing inflammation, and activating the release of endorphins, all of which aim to reduce pain sensation and improve mobility. This study aims to analyze the comparison of INMAS Method Electroacupuncture Therapy and Massage Therapy on Shoulder Pain Reduction. This study uses a Randomized Controlled Trial (RCT) design. In this study using 2 intervention groups. The first group performed electroacupuncture therapy INMAS method, the second group performed massage therapy. Each group amounted to 30 respondents. The results showed that there was a statistically significant difference between the two treatments (Massage and INMAS) with a value of Asymp. Sig. (2-tailed) is 0.000, (p < 0.05). The statistical results also show that INMAS therapy is more effective in reducing shoulder pain compared to massage therapy (Exact Sig value. (1-tailed) is 0.000, p < 0.05). This study concluded from two treatments to reduce shoulder pain with massage therapy and electroacupuncture therapy INMAS method. From the results of the Mann-Whitney test, it was found that electroacupuncture therapy INMAS method was more effective in reducing shoulder pain compared to massage therapy.
