The Evidence for Common Nonsurgical Modalities in Sports Medicine, Part 2: Cupping and Blood Flow Restriction.

OBJECTIVE: There are a number of nonsurgical modalities used by athletes in attempts to improve performance or prevent, treat, and rehabilitate musculoskeletal injuries. A concise review of available evidence on common nonsurgical modalities used today is necessary, so that practitioners may appropriately counsel patients.

METHODS: A comprehensive review of relevant publications regarding cupping and blood flow restriction (BFR) from 2006 through 2019 was completed using PubMed and Google Scholar.

RESULTS: There have been numerous investigations evaluating the efficacy of nonsurgical modalities for a myriad of musculoskeletal conditions. Cupping may be an effective option with low risk in treating nonspecific, musculoskeletal pain. Studies comparing BFR with non-BFR controls suggest that it may increase muscle strength and endurance for individuals undergoing rehabilitation or sport-specific training by mimicking the low oxygen environment during exercise.

CONCLUSIONS: Nonsurgical modalities are low-cost treatment strategies with rates of adverse outcomes as low as 0.008% that will likely continue to increase in popularity. Despite the paucity of recent research in cupping and BFR, evidence suggests benefits with use. High-quality studies are needed to effectively evaluate these treatments, so that care providers can provide appropriate guidance based on evidence-based medicine.
