The Effect of Dry Cupping on Gastrocnemius Muscle Stiffness, Range of Motion and Pain Perception After Delayed Onset Muscle Soreness

Background • Cupping therapy originated in Eastern Medicine, became renowned in complementary medicine and is utilized as a therapeutic treatment in contemporary medicine for musculoskeletal issues. As with any modality, there is a question of efficacy. Objective • This study investigated the effect of cupping therapy on muscle stiffness (MS), active dorsiflexion (DF) and perceived pain of the medial gastrocnemius muscle following a cupping therapy treatment. Methods • Single cohort design included 20 physically active, healthy participants (10 women, 10 men; age: 22.9 years ± 3.35 years) completed an exercise protocol to induce delayed onset muscle soreness in both lower legs. Intervention • A 5-minute dry cupping treatment was performed on the dominant leg medial gastrocnemius and 5 minutes of rest for the non-dominant control leg. Primary Outcome Measures • Muscle stiffness, active dorsiflexion and perceived pain were measured at baseline, pre-treatment, post-treatment and 5 minutes post-treatment in the medial gastrocnemius muscle. A repeated measures ANOVA was used to analyze the main effect and interaction for condition and time. Results • Active DF was significantly different from baseline to pre-treatment, post-treatment and 5 minutes post-treatment (P \u3c .001, P \u3c .001, P = .01, respectively). Pre-treatment to 5 minutes post-treatment, active DF was also significantly different (P = .05). Active DF was significantly improved post-treatment and 5 minutes post-treatment. Baseline pain was significantly different from pre-treatment, post-treatment and 5 minutes post-treatment measurements (P \u3c .001, P \u3c .001, P \u3c .001, respectively). Pre-treatment pain was significantly different from post-treatment and 5 minutes post-treatment pain (P = .009, P \u3c .001, respectively). Post-treatment pain was also significantly different from 5 minutes post-treatment pain (P = .007). MS was not significant at any of the time points (P = .398) or between conditions (P = .140). Conclusion • A single cupping treatment significantly improved active DF and decreased pain was observed in the treatment group. No significant difference in MS was observed following the treatment
