Study Notes
Ankle Inversion from Plantar Flexion
- Muscles involved in ankle inversion from plantar flexion include the tibialis posterior, flexor digitorum longus, and flexor hallucis longus
- The range of ankle inversion is 35 degrees
- Weakness of tibialis posterior causes problems with foot inversion, plantar flexion around the ankle, pronation, and support of the longitudinal arch. It can also impact rising on toes.
- Contracture of tibialis posterior causes equinovarus position in non-weight-bearing and supinated heel position with forefoot varus in weight-bearing.
