The study involved 52 people with carpal tunnel. Part of the group had special glass cups applied to the skin in the shoulder-neck area after 5 to 10 skin punctures with a sterile lancet. A partial vacuum was created using electromechanical or manual suction within the cupping glass after it was applied to the skin.

Those treated with cupping experienced a significant decrease in carpal tunnel syndrome-related pain and other symptoms, compared with the others, the study reported. One treatment improved functional ability and quality of life for a week, and people tolerated treatments very well, according to the study, which appears in the current issue of the Journal of Pain.
