FOOT INVERSION AND EVERSION
FOOT INVERSION Normal and Good Sidelying, ankle in mid-position between plantar and dorsiflexion. Stabilize leg. Avoid pressure over Tibialis posterior muscle. Patient inverts foot through range of motion. Resistance is given on medial border of forefoot. Flexors of the toes should remain relaxed to prevent substitution by the Flexor digitorum longus and Flexor hallucis longus. Note : Inversion combines supination, adduction and plantar flexion. FOOT EVERSION Normal and Good Sidelying, ankle in mid-position between plantar and dorsiflexion. Stabilize leg. Patient everts foot and depressed head of first metatarsal. To test peroneus brevis, resistance is given on lateral border of foot. To test peroneus longus, resistance is given against plantar surface of first metatarsal head. The two muscles may be tested together using a derotating motion as illustrated. Pressure is downward and inward
