The Effects of Lower Limb Orthoses on Health Aspects of the Spinal Cord Injury Patients: A Systematic Review Using International Classification of Functioning, Disability, and Health (ICF) as a Reference Framework

Background: One of the most important approaches in the rehabilitation of spinal cord injury (SCI) patients is the use of different orthoses. To date, no review has been published that analyzed the effects of orthoses on health aspects of spinal cord injury clients using the International Classification of Functioning, Disability and Health (ICF). Methods: A systematic literature search was done in some databases, including Medline, PubMed, Cochrane centered register of the controlled trial (CCTR), Cochrane database of systematic reviews (CDSR), a database of abstracts of reviews of effects (DARE), Embase, Google Scholar, and ISI Web of Knowledge. SCI was used in conjunction with terms like orthotic device, mechanical orthoses, external power orthoses, assistive devices, and functional electrical. The time frame for this search was from 1970 to 2022. Results: A total of 200 papers were found. Based on the titles and abstracts, 100 related papers were detected. After careful evaluation of the papers, 47 studies were selected for final analysis—53 papers were excluded due to duplication, non-English language, and lack of full-text. Conclusion: The results of 32 studies (70% of studies) support the efficiency of orthoses in walking and standing of SCI patients. In most of the included studies, the efficiency of orthoses was evaluated mostly based on body functions and structures, and their impact on other outcomes such as participation and quality of life (QoL) of SCI patients was unclear.
