The use of exoskeleton robotic training on lower extremity function in spinal cord injuries: A systematic review.

Abstract

To perform a systematic review of the utility of exoskeleton robotic therapy on lower extremity recovery in Spinal Cord Injury (SCI) patients. We used the Embase, Cochrane, and PubMed databases and searched from <b>January 2012</b> to December 2023 for studies on exoskeleton robotic assist devices used in working with SCI patients. Only articles published in English were evaluated, and the retrieved articles were screened via our inclusion/exclusion criteria. We conducted our meta-analysis with the Cochrane Review Manager 5.4 (RevMan) software. <b>Robotic assisted gait training and conventional gait training methodology were compared using Walking Index for Spinal Cord Injury II (WISCII), Spinal Cord Independence Measure III (SCIM III), and 6 Minute Walk Test (6MWT) as reported outcome measures.</b> Eleven randomized clinical trials (RCTs) involving <b>552</b> total participants were included in the meta-analysis. The results of the meta-analysis indicated statistically significant improvement in <b>SCIM III [MD 5.14, 95 % CI = (4.47, 5.810), P < 0.00001],</b> WISCII <b>[MD 2.31, 95 % CI = (2.13, 2.49), P < 0.00001]</b> and 6MWT <b>[MD 37.04, 95 % CI = (32.35, 41.74), P < 0.00001]</b> in patients with SCI as compared to conventional gait training (CGT) therapy. <i>Conclusion</i>: Robotic Therapy could improve ambulation/quality of life in patients with spinal cord injuries compared to the standard treatment only, but future studies should include additional measures addressing quality of life and patient satisfaction.
