Study Notes
- The hip joint moves through 40° of sagittal motion in a gait cycle
- At initial contact, the hip is flexed at 25° to 30°
- Hip progressively moves into extension, reaching maximum extension at 10° of hyperextension by terminal stance
- Hip hyperextension at terminal stance is accompanied by extension of the lumbar vertebrae and an anterior pelvic tilt
- Hip begins movement towards flexion during preswing as it prepares to lift the limb off the ground
- By the end of stance, the hip is near neutral
- During swing phase, the hip continues a steady increase into flexion until midswing when the hip is slightly more than 30° of flexion
- After midswing, its flexion decreases slightly and is maintained until terminal swing
- These typical sagittal plane excursions occur during normal walking speed but are slightly higher in fast walking
- Trunk moves forward over the foot and continues its forward movement to advance in front of the foot after midstance
