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.

RESEARCH OBJECTIVE:

The primary objective of this study is to examine the efficacy of true dry cupping therapy, in combination with routine physiotherapy, in comparison to sham dry cupping therapy, in combination with routine physiotherapy, for managing pain intensity and functional disability in individuals with chronic non-specific low back pain. The secondary objective is to evaluate the impact of 10 treatment sessions on the quality of life of patients with chronic non-specific low back pain.

RESEARCH DESIGN:

This study is a randomized, single-blind, sham-controlled trial conducted at two centers. The allocation ratio is 1:1, with a total of 80 participants with hypertrophic scar tissue. Random assignment to two groups of equal size will be done using the permuted block randomization method, utilizing four-letter blocks (A and B). The random treatment list will be placed in sealed and numbered envelopes, with letter A representing true dry cupping therapy and letter B representing sham dry cupping therapy. The random assignment process will be conducted by an individual outside the research team prior to the commencement of the study.

PROCEDURE:

At the beginning of the study, potential participants will undergo an assessment to determine their eligibility based on specific criteria. Once confirmed by an orthopedic surgeon, participants will be enrolled in the study. Eligible participants will be asked to complete an intake form, providing demographic data such as age, gender, height, weight, occupation, and information regarding major confounding variables like smoking and depression that may affect low back pain. Following that, participants will be requested to complete questionnaires assessing pain intensity, functional disability, and quality of life.

INTERVENTION:

After the baseline assessment, the principal investigator will administer dry cupping therapy to the intervention group consisting of 24 enrolled patients. The participants in this group will be asked to lie in a prone position, and the lumbar area between L1-L5 will be oiled. Two cups with a diameter of 4.5-5 cm will be placed bilaterally parallel to the lumbar spine vertebrae. The therapist will then perform dry cupping therapy by applying two suctions and moving the cups in an up-down and down-up direction for 5 minutes using both hands.

In contrast, the control group will assume the same positions as the intervention group, but the cups will be placed stationary for 5 minutes only. The cups in the control group will have small holes with a diameter of less than 2mm to release negative pressure within seconds. Double-sided tapes will be used to secure the cups and maintain contact with the skin.

Both groups will undergo routine physiotherapy, which includes a 20-minute session of transcutaneous electrical stimulation. The stimulation will be set at a frequency of 100 pulses per second and a duration of 60 microseconds. The intensity of the stimulation will be gradually adjusted until participants experience a sensory stimulus during the 20-minute session. Stabilization exercises such as abdominal hollowing and bridging exercises will also be included in the treatment.

The entire treatment duration will consist of 10 sessions, conducted three times per week.

REASSESSMENT:

After the interventions, measures of the primary and secondary outcomes will be collected immediately and two weeks after the final treatment session to evaluate the effectiveness of the cupping therapy intervention. Additionally, any adverse events following the cupping therapy procedures and adherence to the treatment will be assessed.

Inclusion Criteria:

• Chronic non-specific low back pain lasting for a minimum of 3 months.
• The pain intensity is rated between 3 and 6 on the visual analog scale.
• The body mass index falls between 19 and 23.
• No restrictions for therapeutic exercise and electrotherapy.

Exclusion Criteria:

• The presence of comorbidities such as diabetes and cardiovascular problems.
• The presence of spinal column deviations, such as scoliosis, is observed.
• Signs of serious pathology of the spine (eg, fractures, inflammatory diseases, infection or tumours).
• Consecutive absence of more than three sessions.
• Patients' dissatisfaction with their participation in the study
• Individuals who have been treated with cupping in the past.
• Neurological, vestibular, visual or auditory deficits.
• Currently performing physical therapy.
• Irradiated lumbar or sacroiliac pain.
• Fibromyalgia

Single (Participant) Participants in the control group will undergo a similar procedure to those in the intervention group. Two cups will be placed on the lumbar region, but the sham cups will have small holes (<2mm in diameter) to release negative pressure quickly. Additionally, to reduce bias, the data analyst will be blinded to the group assignments of the participants. Each participant will be identified by a unique numerical code to maintain anonymity.
