Objective:Walking with lower limb orthosis for people with spinal cord injuries is acommon problem for patients referred to orthopedic centers, many of whichcause physical problems for the patient and some of which causephysiological problems.Method:The disease was selected with spinal cord injury, which was tested with twoconventional and new orthosis. Experiments were also performed on ahealthy person. Gait analysis was performed to evaluate the kinematicparameters in this study.Findings:The maximum and minimum points of the curve related to angular and linearacceleration as well as linear and angular velocities at the wrist joint wereobtained on the XZ sagittal plate.Conclusion:Based on this study, it is found that by placing the wrist joint to the orthosis,the patient can walk more easily and the movement pattern is closer to thehealthy person.
