Effectiveness of Cupping Therapy in Patients With Chronic Nonspecific Low Back Pain: a Randomized Sham-controlled Trial

Chronic non-specific low back pain is a common condition that can cause disability, physical and psychological impairment, limitations in daily activities, and participation restrictions. It also has significant economic and social impacts. Clinical guidelines recommend non-pharmacological interventions as the first-line treatment, including exercises, psychological therapies, and multidisciplinary rehabilitation. Pharmacological therapies are used when non-pharmacological approaches are not effective. Alternative therapies like cupping therapy have gained attention, but their efficacy is still debated due to limited high-quality studies. Further research is needed to determine the true benefits and effectiveness of cupping therapy in managing chronic low back pain. A recent study found that dry cupping therapy was not superior to sham cupping in improving pain, physical function, mobility, quality of life, psychological symptoms, or medication use in individuals with chronic non-specific low back pain. However, it's important to note that the study used dry cupping therapy in isolation, which may not reflect typical clinical practice. Well-designed clinical trials can provide a better understanding of the potential impact of cupping therapy on various aspects of chronic low back pain. Hence, the primary goal of this randomized clinical trial is to compare the effectiveness of true cupping therapy combined with routine physiotherapy versus sham cupping therapy combined with routine physiotherapy in patients suffering from chronic non-specific low back pain. The study aims to address the following key questions:

• Does true dry cupping therapy, when combined with routine physiotherapy, provide greater improvement in pain and functional disability for patients with chronic non-specific low back pain?
• Does true dry cupping therapy, when combined with routine physiotherapy, result in a higher improvement in quality of life for patients with chronic non-specific low back pain?

Participants in the intervention group will undergo 10 sessions of dry cupping therapy, with each session lasting 5 minutes and conducted three times per week. During the sessions, the therapist will move the cups longitudinally in upward-downward and downward-upward directions. In the control group, participants will assume the same positions as the intervention group, but two cups with small holes (<2mm in diameter) will be used to release negative pressure within seconds.
