The Effects of Lower Limb Rehabilitation Robots on Range of Motion and Balance in Patients with Stroke

The purpose of this study is to investigate the effect of lower extremity rehabilitation robot training on range of motion (ROM) and balance ability in chronic stroke patients, thereby providing basic data for effective rehabilitation intervention strategies. The subjects were 40 stroke patients who were randomly assigned to an experimental group (n=20) and a control group (n=20). The experimental group performed bridge exercises and gait training using the Angel Robotics walking robot for 20 minutes, while the control group performed bridge exercises and manual resistance exercises provided by a therapist. The intervention was conducted for 4 weeks. To compare the effects before and after the intervention, the ROM of the hip and knee joints was measured using an electronic goniometer, and the Berg Balance Scale (BBS) was assessed. First, regarding the changes in ROM for hip flexion and knee flexion, the experimental group, which combined lower extremity rehabilitation robot training, showed a statistically significant improvement compared to the control group (p
