Shortly after, as the foot becomes flat on the ground, the knee gradually flexes approximately 10-15 degrees reaching the maximum at about 15% of the gait cycle. [3] This small amount of knee flexion is controlled eccentrically by the knee extensor muscles which serve the purpose of cushioning the rate of loading on the lower limb and ...
Pronation is a natural movement of the foot that occurs during foot landing while running or walking. Composed of three cardinal plane components: subtalar eversion, ankle dorsiflexion, and forefoot abduction, [1] [2] these three distinct motions of the foot occur simultaneously during the pronation phase.

Walking or bipedal gait is usually assessed clinically unless there is a neuromuscular condition, such as cerebral palsy. Laboratory based gait analysis can be very useful for planning treatment regimes, especially surgical management, but also the effects of ankle-foot-orthoses (AFO's) and footwear.
Pigeon toe, also known as in-toeing, is a condition which causes the toes to point inward when walking.It is most common in infants and children under two years of age [1] and, when not the result of simple muscle weakness, [2] normally arises from underlying conditions, such as a twisted shin bone or an excessive anteversion (femoral head is more than 15° from the angle of torsion) resulting ...
Angular motions (or rotary motions) occur when an object is around another object increasing or decreasing the angle. The different parts of the object do not move the same distance. Examples include a movement of the knee, where the lower leg changes angle compared to the femur, or movements of the ankle. [2]
Proper alignment of the prosthetic foot about the ankle joint causes metabolic cost [48] and gait symmetry at the anatomical hip and knee joints to improve, with hip flexion-extension motion being the most sensitive to alignment. [62] Excessive rotational misalignment of the foot is compensated by internal rotation of the residual hip joint. [63]
Hip-knee-ankle angle. On projectional radiography, the degree of varus or valgus deformity can be quantified by the hip-knee-ankle angle, [7] which is an angle between the femoral mechanical axis and the center of the ankle joint. [8] It is normally between 1.0° and 1.5° of varus in adults. [9] Normal ranges are different in children. [10]
