Explanation / Answer
When a subject is walking on level ground, the movements of the lower limbs may be divided into "swing" and "stance" phases, which are separated by heel-strike. The swing phase occurs when the limb is off the ground, and the stance phase when it is in contact with the ground and is bearing weight.
1.A.knee extension angle and hip extension angle-This position actually supports the body during heel strike as both joints have a maximum extension at heel contact
2.b. ankle dorsiflexion angular velocity and hip flexion angular velocity.-
3.a.ankle dorsiflexion angle and knee extension angle -a significant reduction in ankle dorsi-flexion at mid stance occurs.
4.d.B. ankle dorsiflexion angular velocity and knee flexion angular velocity
