PHTY210 Lecture Notes - Lecture 14: Sagittal Plane, Hip, Weight-Bearing
Document Summary
Pathological gait: hip: normal hip kinematics, within gait cycle, 1 period of flexion, 1 period of extension. Function of the hip in gait: stance: hip extension occurs from ic to ho (peak hip extension at ho, function: weight bearing stability. Lateral tilt (pelvic drop) - 4 : normal pelvic motion, normal pelvic motion during gait involves. Lateral shift of pelvis (as body moves from r leg single support to l leg single support: deviations at the hip may involve altered pelvic position or motion. Recall possible primary deviations that may occur at the hip joint. Sagittal plane: excessive hip flexion/lack of hip extension, hip is flexed more than it normally should be for a given phase, excessive hip extension/lack of hip flexion, less than normal hip flexion for a given phase. Frontal plane: excessive hip adduction/lack of hip abduction, greater than normal hip adduction for a given phase, normal frontal plane motion.
