Background: Myogenic low back pain is on of the most common musculoskeletal disorders experienced by workers, particularly those engaged in repetitive tasks and non-ergonomis working positions, such as fish-smoking workers. This condition may lead to muscle spasms, pain, and restricted movement in the lumbar region. Objective: This study aimed to determine the effect of combining massage gun therapy and tapping on pain intensity and range of motion among workers with myogenic low back pain at the Bandarharjo Fish Smoking Centre in Semarang city. Methods: This study employed a quasi experimental method with a one group pre-test and post-test design. The sample consisted of 30 workers. The intervention was administered for four weeks with a frequency of three sessions per week and included massage gun therapy and tapping. Pain intensity was measured using the numeric rating scale, while lumbar range of motion was assessed using a goniometer. Results: Data were analysed using the Wilcoxon signed-rank test. The results demonstrated a significant reduction in pain intensity and a significant improvement in lumbar range of motion across all movement direstions following the intervention (p <,0,001). Conclusion: The combination of massage gun therapy and tapping was found to have a significant effect on reducing pain intensity and improving lumbar range of motion in workers with myogenic low back pain.
