Outcomes of Endoscopic Carpal Tunnel Release Surgery With Home Guided Hand Therapy Versus No Hand Therapy: A Prospective Randomized Controlled Trial After Endoscopic Carpal Tunnel Release

Abstract

Background: The most recent American Academy of Orthopaedic Surgeons Clinical Practice Guidelines found no high-quality evidence comparing home therapy to no therapy following carpal tunnel release surgery (CTRS). Therefore, this study’s purpose is to compare the outcomes of patients receiving home therapy and patients receiving no therapy following endoscopic CTRS. Methods: A single-blinded prospective randomized controlled trial was performed. Patients were randomized to receive home hand therapy or no therapy postoperatively. Patients were assessed at baseline, 2, 6, and 12 weeks postoperatively. Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) scores and Boston Carpal Tunnel Questionnaire (BCTQ) scores were evaluated as primary outcome measures. Grip strength, pinch strength, numerical pain rating scale (NRS), static 2-point discrimination, and hand circumference were also measured. Results: Fifty patients were randomized to home therapy while 55 patients were randomized to no therapy. The QuickDASH, BCTQ functional status scale (FSS), and BCTQ symptom severity scale (SSS) improved over time in both treatment groups. As-treated and intention-to-treat analysis showed no difference in improvement of QuickDASH, BCTQ FSS, or BCTQ SSS between treatment groups. Additionally, there was no significant difference between treatment groups in grip strength, chuck and key strength, NRS, hand circumference, and static 2-point discrimination. Conclusions: This blinded, prospective randomized controlled study shows no significant difference in improvement of QuickDASH, BCTQ SSS, and BCTQ FSS scores between patients receiving no therapy and home therapy following endoscopic CTRS. Consideration should be given to releasing patients without supervised therapy in the postoperative setting. Level of Evidence: Level II Therapeutic

The significance of wrist immobilization for endoscopic carpal tunnel release

“…The change in postoperative strength showed a similar tendency to postoperative pain ( 13 , 28 ). It took nearly 2 months for both groups to recover normal strength, which could provide a reference for the therapist to formulate accurate postoperative physiotherapy.…”
