Effectiveness of Traditional Chinese “Gua Sha” Therapy in Patients with Chronic Neck Pain: A Randomized Controlled Trial

OBJECTIVE Gua sha is a traditional East Asian healing technique where the body surface is press-stroked with a smooth-edged instrument to intentionally raise therapeutic petechiae. A traditional indication of Gua sha is neck pain; no data from controlled trials exist to support this claim. The researchers aimed to investigate the effectiveness of Gua sha in the symptomatic treatment of chronic neck pain. DESIGN The study was designed as an open randomized controlled clinical trial. SETTING The study was set in Kliniken Essen-Mitte, Academic Teaching Hospital of the University Duisburg-Essen, Germany. SUBJECTS Forty-eight outpatients (58.5±8.0 years; 41 female) with chronic mechanical neck pain were the subjects of the study. INTERVENTION Patients were randomized into Gua sha (N=24) or control groups (N=24) and followed up for 7 days. Gua sha patients were treated once with Gua sha, while control patients were treated with a local thermal heat pad. OUTCOME MEASURES Primary outcome was change of neck pain severity after 1 week as assessed by visual analog scale. Secondary outcomes included pain at motion, the neck disability index (NDI) and quality-of-life (Short-Form [36] Health Survey). RESULTS Neck pain severity after 1 week improved significantly better in the Gua sha group compared with the control group (group difference -29.9 mm, 95% confidence interval: -43.3; -16.6 mm; P<0.001). Significant treatment effects were also found for pain at motion, scores on the NDI, and dimensions of quality-of-life. The treatment was safe and well tolerated. CONCLUSION Gua sha has beneficial short-term effects on pain and functional status in patients with chronic neck pain. The value of Gua sha in the long-term management of neck pain and related mechanisms remains to be clarified.

Did dry cupping cause anaemia

In a September 2012 case report in this journal, Kim et al 1 describe a 77-year-old woman who presented to their clinic with back and leg pain and a diagnosis of lumbar stenosis that had not responded to conventional conservative management or to repeated sessions of traditional Korean cupping therapy. The authors report that 3 months before their initial meeting with the patient she had had 30 sessions of dry cupping therapy and was subsequently treated for anaemia at another hospital. They assert that her anaemia was ‘…possibly associated with persistent blood loss …
