Study Notes

Pronation and supination occur through subtalar and transverse tarsal joints.
Pronation combines eversion, abduction, and dorsiflexion; supination combines inversion, adduction, and plantar flexion.
Subtalar joint motions are measured as the angle between the calcaneus and the lower leg.
The subtalar joint is inverted 2-3 degrees at heel contact and rapidly everts until mid stance.
The subtalar joint then reverses direction towards inversion and reaches a neutral position at heel off.
Calcaneal inversion continues until it reaches approximately 6 degrees of inversion.
The reported amount of foot pronation during gait varies based on measurement techniques.
Foot pronation or supination during walking is accompanied by changes in height of the foot's medial longitudinal arch.
Individuals with pes planus demonstrate a greater amount of rearfoot pronation when walking.
More information on associated kinesiology is provided in Chapter 14.
