BIOL 115 Lecture Notes - Lecture 16: Sagittal Plane, Transverse Plane, Weight-Bearing
Document Summary
Motion pelvis on femur by pelvis on femur. When hip is weight- bearing femur is relatively fixed and motion of hip is produced. Anterior/posterior pelvic tilt- motion of entire pelvic ring in sagittal plane around frontal axis. Results in motion at both hips simultaneously in bilateral stance. Occur in stance limb alone if opposite limb nwb. Lateral pelvic tilt- frontal plane motion of entire pelvis around sagittal axis. Unilateral stance- one hip axis of motion for opposite side pelvis. Bilateral stance- hip and knee flexion of 1 limb while both feet remain on floor (opposite limb largely wb) Lateral tilt causes pelvic shift to side. Pelvis shift to right in bilateral= left side pelvis drops, left hip abd and right hip add. Forward/backward pelvic rotation- motion of pelvic ring in transverse plane around vertical axis of wb hip (commonly occurs in single limb support.
