Abstract: Objective To explore the 3D gait analysis of stroke hemiplegic patients. Methods 28 stroke hemiplegic patients were examined with the 3D gait analysis system before and after 6-week rehabilitation. Results After rehabilitation, support phase time of the affected lower limb increased and swing phase time decreased (P<0.05). Step length, stride length and walking speed increased (P<0.05). There was significantly difference in range of motion (ROM) of hip deduction/abduction, flexion/extension, and knee flexion/extension, and ankle internal/external rotation, varus/eversion, dorsiflexion/plantar flexion before and after rehabilitation (P<0.05). Conclusion 3D gait analysis system can evaluate the patient's gait objectively and quantitatively, and provide the basis for rehabilitation assessment.
