The Effects of Stretching Versus Static and Dynamic Cupping on Lumbar Range of Motion

The objective of this study is to fill gaps in the literature regarding the effectiveness of cupping therapy on lumbar stiffness. Participants will be recruited from the University of South Carolina and from local clinics in Columbia, South Carolina. Individuals will be classified based on lumbar range of motion limitations, and then they will be equally dispersed into three treatment groups via stratified randomization. These groups include dynamic cupping, static cupping, or stretching. All participants will be assessed prior to selected treatment to obtain baseline values for four measures: back range of motion (BROM), pain pressure threshold (PPT), active straight leg raise (ASLR), and numeric pain rating scale (NPRS). Participants will be given each measure directly after treatment, followed by a follow-up measurement 24 hours after treatment.
