Isometric inversion and eversion. This exercise is used to begin to strengthen the ankle invertors (tibialis posterior) and evertors (peroneals) in the early stages of treatment.
- To strengthen the invertors, the athlete pushes the inside of the foot against a table or chair leg, trying to turn the foot inwards against resistance.
- To strengthen the evertors, the athlete pushes the outside of the foot against a table or chair leg, trying to turn the foot outwards.
- This exercise can also be performed with a therapist providing the resistance.
