| Outline of Final Research Achievements |
We examined the effects of pelvic movement limitation on the mechanical efficiency of walking, the kinematic parameters of the lower limbs and trunk, and lower limb muscle activity. We asked healthy young adults to walk on a walking path under these conditions that artificially induced leg length discrepancy, restricted movement of the trunk, hip, or knee joint. The kinematic and kinetic parameters of walking were compared with those obtained without restriction. For comfortable speed walking, healthy young people showed that various compensatory movements worked on lower limb joints under any condition. The mechanical efficiency of movement of the center of gravity during walking was preserved. Results of this study are expected to be useful as control data for evaluating the walking of patients who have restricted or asymmetric movement of the pelvis caused by aging and various impediments.
