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]
Range of motion (or ROM) is the linear or angular distance that a moving object may normally travel while properly attached to another. In biomechanics and strength training , ROM refers to the angular distance and direction a joint can move between the flexed position and the extended position. [ 1 ]
So, during subtalar inversion, the calcaneus also rotates clockwise and translates forward along the axis of the screw. Average subtalar motion is 20-30 degrees inversion and 5-10 degrees eversion. Functional motion during the gait cycle is 10-15 degrees (the heel strikes the ground in slight inversion followed by quick eversion). [2]
The range of motion for plantar flexion is usually indicated in the literature as 30° to 40°, but sometimes also 50°. The nerves are primarily from the sacral spinal cord roots S1 and S2. Compression of S1 roots may result in weakness in plantarflexion; these nerves run from the lower back to the bottom of the foot.
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 ...
Eversion and inversion: Stretching the eversion and inversion muscles allows for better range of motion to the ankle joint. [38] Seated ankle elevations and depressions will stretch the fibularis (peroneus) and tibilalis muscles that are associated with these movements as they lengthen. Eversion muscles are stretched when the ankle becomes ...

The deltoid ligament supports the ankle joint and also resists excessive eversion of the foot. [1] The deltoid ligament is composed of 4 fibers: Anterior tibiotalar ligament; Tibiocalcaneal ligament; Posterior tibiotalar ligament; Tibionavicular ligament. It consists of two sets of fibers, superficial and deep.
