Supination Resistance test

Supination Resistance test:
Used to determine how much force is needed to supinate the foot (add refs).

Technique:
• patient standing in relaxed angle and base of gait
• two fingers are placed on the medial side of the talonavicular joint
• patients is instructed to relax and not assist
• the foot is supinated by applying a force in a dorsal direction
• (alternatively, a superiorly directed force is applied to the plantar medial aspect of the navicular)
• the amount of force needed is noted
• the force can be rated from 0/5 (easy) to 3/5 (moderate) to 5/5 (hard)

Reliability – shown to be reliable when used by experienced clinicians (add ref)

Mechanical device to test this has been described (add ref)

Clinical use:
• shown to be related to subtalar joint axis position (add ref)
• the amount a foot is pronated was poorly correlated to the amount of force needed to supinate it (add ref)
• the greater the supination resistance test, the greater force that may be needed from a foot orthoses (add ref)
• generally different pathologies are related to different amounts if supination resistance (add more detail and ref)
