The Effect of Text Message-based Support Program (TextRehab) on Treatment Outcomes of Patients with Hand Flexor Tendon Injuries after Repair: A Randomized Controlled Trial Study Protocol

Background: Post-operative rehabilitation for patients with flexor tendon injuries is necessary for a full recovery. Thisrandomized controlled trial study investigates the effectiveness of a text message-based rehabilitation program (i.e.,TextRehab) on the improvement rate of hand rehabilitation in patients with flexor tendon injuries after repair.Methods: This study is designed as a randomized, three-month, single-center, two-arm, parallel controlled trial. A total of 40 patients will be randomly classified as either the control or intervention group. Both groups receive usual care; however, the intervention group is also asked to perform the designed rehabilitation activities through the TextRehab program. The activity instructions are sent to patients step by step at least once a day. Self-reported outcomes will beassessed at 6 and 12 weeks after discharge and include self-reported Patient Rated Wrist Evaluation, self-reported Quick-Disability of Arm, Shoulder, and Hand, and Visual Analogue Scale. Moreover, the reports of the physicianregarding the grip strength and Total Active Motion will be assessed at week 12. Results: The development of the message scheduling system and its contents is completed. This trial has the code of ethics in research(IR.MUMS.fm.REC.1396.247). Study results are expected to be available in mid-2021.Conclusion: The TextRehab program is developed to provide advice, motivation, information, and care for patientswith hand flexor tendon injuries after repair. This trial provides evidence of the effectiveness of sending text messageson persuading patients to perform home-based rehabilitation activities.
