Background: People with incomplete spinal cord injury disabilities can be able to live a healthy, productive, and dignified life by using Assistive devices as their role in improving gait. Facilitate locomotion rehabilitation. And enable people with incomplete SCI to ambulate in an upright position. Objective: This systematic review aimed to examine the effectiveness of the role of using assistive devices in gait rehabilitation in patients with incomplete SCI. Material and Methods: Studies were identified from 2000 to 2020 by electronic search using PubMed, Cochrane Database of Systematic Reviews, Google Scholar, and Physiotherapy Evidence Database (Pedro). They were reviewed if they were randomized control trials focused on the effectiveness of Assistive Devices on Gait in Patients in age more than 18 years with incomplete Spinal Cord Injury being published in English. Eight studies were selected according to inclusive and exclusive criteria and descriptive analysis was conducted due to heterogeneity. Results: Eight trials were identified with good quality methodology. Descriptive analysis was applied for three studies that supported the use of assistive devices for those patients and meta-analysis was applied for five studies. The mean difference across all the five studies is -0.69 (95% CI -0.93, -0.45). According to AACPDM, there is level II evidence that supports the use of the assistive device as a method to be able to live a healthy, productive, and dignified life. Conclusion: The current level of evidence supports the effectiveness of assistive devices in improving gait in patients with incomplete spinal cord injury.
