Effects of Percussion Therapy on Delayed Onset Muscle Soreness
Location
Loosemore Auditorium
Description
PURPOSE: Percussion therapy, or massage gun application, has grown in popularity as a method for patients that endure symptoms of delayed onset muscle soreness (DOMS). There is little research on the effects of percussion therapy. At peak soreness the serial application of percussion therapy may show significant results in decreasing the symptoms of DOMS. The purpose of this study was to assess the efficacy of percussion therapy, via serial massage gun application, on individuals that are induced with DOMS in the biceps muscles. METHODS: Twenty-nine (16 male/13 female) individuals were enrolled in this study. Assessments were completed in four days over two weeks. On day one, visual analog scale (VAS) and pain pressure thresholds (PPT) were taken for the medial biceps. One rep max (1RM) was calculated using the Brzycki equation. On day two, one week later, 70% of their 1RM was used as their weight for fatigue protocol. The remaining days were 48 and 72 hours after the protocol; PPT and VAS were recorded pre-intervention and post-intervention for the treatment arm, and the control arm received only measurements. RESULTS: PPT pre, 48 hours, and 72 hours did not show significant improvement. Huynh-Feldt test of within-subjects effects yielded a result of p=.430 CONCLUSION: There was no improvement in level of soreness between days of treatment. We predict that there will be significant results pre-intervention compared to post-intervention in VAS and PPT once data collection is complete.
