As a weak dorsiflexor of the ankle joint, the fibularis tertius assists in pulling the foot upward toward the body. It also assists in tilting the sole of the foot away from midline of the body at the ankle . It is likely to be helpful though not essential in bipedal walking. [4]
Inversion and eversion are movements that tilt the sole of the foot away from (eversion) or towards (inversion) the midline of the body. [35] Eversion is the movement of the sole of the foot away from the median plane. [36] Inversion is the movement of the sole towards the median plane. For example, inversion describes the motion when an ankle ...
The quad stretch targets the quadriceps and hip flexor muscles as you stand on one leg and bend the knee of the other leg while grabbing the opposite foot, pulling it toward your rear.
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. [3]
With a forefoot strike, the ankle and knee joints release their stored elastic energy from the footstrike/absorption phase. [33] [34] [35] The quadriceps group/knee extensors fully extend the knee, pushing the body off the ground. Simultaneously, the knee flexors and stretch reflex pull the knee back into flexion, initiating the initial swing ...
Bridging exercises are done with a flexed knee to lessen the stretch on the hamstring (a knee flexor) and focus the hip extension work on the gluteus maximus. In that same respect, the reduced knee flexion makes plantar flexion work comparable to a seated calf raise, due to the lessened stretch on the gastrocnemius (like the hamstring, also a knee flexor).
The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed. It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it. A positive result would be the jerking of the foot towards its plantar surface.
