Massage Therapist Practice Exam

Answer: B To check for a tight tibialis anterior muscle you would length the muscle bringing the ankle into plantarflexion. Since the tibialis anterior is located on the lateral anterior shaft of the tibia, crosses the ankle and inserts on the base of the 1^st metatarsal, the muscle's natural action is dorsiflexion and lateral rotation of the ankle. In order to lengthen any muscle, perform the opposing muscle action.
