Dry Cupping Therapy for Neck Pain: Monitoring for Adverse Effects
摘要
Cupping therapy is a traditional complementary technique that uses negative pressure (vacuum) under the skin to provide short-term relief from musculoskeletal pain. However, the scope of potential adverse effects (AEs) is substantial, and rigorously designed studies evaluating its safety and efficacy are lacking. The purpose of this study was to develop a reproducible device for pressure measurement in cupping therapy and to investigate the AEs reported by subjects following dry cupping applied to the neck.
MethodsA prospective, double-arm, double-blind study was conducted. A device was developed to maintain and measure negative pressure during dry cupping therapy. The sample was divided into two dry cupping groups with different pressures: − 150 and − 300 mm of mercury (mmHg). A questionnaire formulated by the author recorded AEs during, immediately after, and 24 and 72 h after the intervention. Female subjects between 18 and 59 years of age who met the inclusion and exclusion criteria were the population of this research. For the intervention, dry cupping therapy was applied to the neck using two pressure levels (− 150 and − 300 mmHg), and AEs were reported via a standardized questionnaire administered immediately, and at 24 and 72 h after cupping relief. A mixed-effects ANOVA followed by Tukey's post hoc test was used to compare the variance between the groups.
ResultsThe developed device effectively maintained negative pressure during cupping therapy. Localized pain was reported in both groups during application. "Stinging" and radiating pain were also noted. At 24 h, bruising persisted in the − 300 mmHg group, and headache symptoms increased in both groups. By 72 h, AEs remained primarily in the − 300 mmHg group (bruising and/or pain).
ConclusionsThe developed device offers a valid alternative for standardizing cupping therapy studies. Higher pressure levels appear to be associated with a greater incidence and longer duration of AEs.
