Effect of Transfer Energy Capacitive and Resistive Therapy on Shoulder Pain, Disability, and Range of Motion in Patients With Adhesive Capsulitis: A Study Protocol for a Randomized Controlled Trial

Abstract

Objective: We describe a protocol to evaluate the effectiveness of transfer energy capacitive and resistive (TECAR) therapy on shoulder passive range of motion, shoulder pain, and disability index in patients with adhesive capsulitis. Methods: This study will be a double-blinded randomized clinical trial with a 1-month follow-up. For the purpose of this research, 30 patients with a 3-month history of shoulder pain and disability diagnosed as adhesive capsulitis will be selected and then randomized into 2 groups, including conventional physiotherapy consisting of electrophysical modalities and therapeutic exercises, which will be given to the control group. In the intervention group, after conventional physiotherapy, 10 minutes of TECAR therapy in resistive mode will be applied on both the anterior and inferior aspects of the shoulder joint. Outcome measures will be related to shoulder passive range of abduction, flexion, and external rotation that will be measured using a digital inclinometer, as well as shoulder pain and disability index that will be assessed by the validated questionnaire. Assessment will be done at baseline, 1 day after the intervention, and by passing 1 month. Results: The statistical analysis will describe within-group and between-group comparisons; the findings will be illustrated in tables and charts. Conclusion: Given the reason that the effectiveness of TECAR therapy has not been widely evaluated in adhesive capsulitis, the findings of this pilot study would provide baseline information on the effectiveness and complications of this treatment method and possibly propose a more appropriate protocol for patients with adhesive capsulitis.
