Abstract
To perform rehabilitation critically after a lower leg surgery, we underwent gait analysis periodically for each patient. The patients are 2 cases of total hip joint arthroplasty-3 cases of total knee joint arthroplasty-1 case of high tibial osteotomy and 1 case of acetabular fracture. The gait analysis was performed on the force plate, touching the parallel hand bars, bridging the force plate, in either one or two weeks, Z (vertical) direction force, Y (forward) direction force, X (medial-lateral) direction force, gait cycle time, stance phase time (ratio to sound side stance phase), single support time (ratio to stance phase time) are measured. Finally, Z (vertical) direction force and gait cycle time are good parameters for post operative recovery process. Secondaly, stance phase time and single support time are relatively good parameters.
