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.
