Efficacy of Acupuncture for Shoulder Pain Based on Remote Point Selection According to the Meridians

Efficacy of Acupuncture for Shoulder Pain Based on Remote Point Selection According to the Meridians

This double blind randomized controlled trial investigates the immediate efficacy of acupuncture for shoulder pain using remote point selection based on meridian theory. A total of 90 participants with shoulder pain (Numerical Rating Scale ≥ 4) will be randomly assigned in a 1:1:1 ratio to one of three groups: acupuncture SC, acupuncture CS, and rehabilitation. Meridian selection will be determined based on the patient's most painful shoulder movement and corresponding pain location, followed by standardized distal acupoint application. Outcome measures include changes in pain intensity (NRS) and shoulder range of motion assessed at baseline, post-first acupuncture, post-second acupuncture, and 30 minutes post-treatment. Blinded evaluators will conduct all assessments. The study aims to assess the effectiveness of meridian-based remote acupuncture and explore its relationship with shoulder movement patterns and soft tissue involvement.

Inclusion Criteria:

• Participants must be at least 18 years old.
• Shoulder pain persisting for at least one week.
• Numerical Rating Scale (NRS) score ≥ 4.

Exclusion Criteria:

• Patients with cervical radiculopathy or other localized neurological disorders affecting the upper limb.
• Psychiatric disorders that may interfere with examination, treatment, or evaluation of disease progression.
• Pregnant patients.
• Inability to provide informed consent.
