Study Notes
- Kinematics of walking has been studied and recorded.
- Sagittal plane motions are the largest and easiest to track.
- Displacement in the frontal and transverse planes is smaller and more difficult to measure.
- Joint motions during gait are highly consistent.
- Body's center of motion oscillates in the sagittal and frontal planes of motion during walking.
- COM moves up and down twice during one gait cycle in the sagittal plane.
- COM moves once from left to right in the frontal plane.
- Movements at each of the joints during the gait cycle are presented in each of the body's three planes of motion.
- Results for displacement in frontal and transverse planes are less accurate and reliable.
- Patterns and sequence of joint motions during gait are highly consistent.
