1 Design of a Novel Passive Pelvic Orthosis for Gait Rehabilitation Using 3D Dynamic Model Ali Mokhtarian alimokhtarian@me iut ac ir March 10 2013 Department of Mechanical Engineering Isfahan University of Technology Isfahan 84156 83111 Iran A Fattah61 fattah@cc iut ac ir Supervisor M Keshmiri62 mehdik@cc iut ac ir Advisor M R Salimpour Department Graduate Program Coordinator Abstract In this thesis we design a novel gait rehabilitation passive orthosis to training the people who lost their walking ability due to neurological injuries such as spinal cord injury and stroke As known the movements of pelvis play an important role in balance and propulsion during a gait cycle In this research we present and simulate a passive orthosis to assist the motion of pelvis of gait patients for regaining their initial walking pattern This optimized pelvic device is un motorized and contains only passive elements The accomplished simulations are based on presentation of a proper 3D dynamic model of human body by focusing on motions of lower legs during gait on treadmill Based on solutions of direct dynamics and inverse dynamics two optimization problems are defined to derive optimum structural parameters of orthosis The optimization results of direct dynamics show that the optimized time trajectories of pelvic rotations are close to corresponding desired diagrams Also by simulating the inverse dynamics we could obtain the minimum values of torque vector of assumed actuator of hip joint of stance leg Furthermore the fabrication of device is performed and experimental results are presented However to validate modeling and study the feasibility of using device we conduct the initial experiments on a healthy subject We study a rotational movements of pelvis and b energy expenditure of subject with and without device during walking on treadmill Increasing range of motion of pelvic and decreasing energy consumption upon using device confirm the validation of simulation results and proper performance of device for gait rehabilitation Keywords Pelvic rotations Gait Passive orthosis Dynamic model Optimization Experimental results 61 Assistant Professor Department of Mechanical Engineering Isfahan University of Technology 62 Associate Professor Department of Mechanical Engineering Isfahan University of Technology PDF created with pdfFactory trial version www pdffactory com
