Abstract:
OBJECTIVE: To evaluate characteristic gait patterns of transfemoral amputees who have been using polycentric knee for a long time. METHOD: Subjects were 22 transfemoral amputees using prosthesis for 29.0 years and 23 age-matched healthy adults. The three-dimensional gait analysis was performed. Temporospatial, kinematic and kinetic parameters were measured. RESULTS: Cadence and walking velocity of amputees decreased (p<0.05). Single support period decreased in amputee limb. There were no significant differences in hip flexion moment and power. In amputated limb, knee flexion in loading response was not observed and ankle plantar flexion was less than sound limb and control group. Excessive compensations of amputee side hip joint were not significant. CONCLUSION: Long term polycentric knee unit transfemoral prosthesis users show asymmetry of gait pattern which can increase the risk of musculoskeletal problems. Epidemiologic investigation would be necessary for prevention and proper management.
