Ankle Testing - Inversion

Ankle sprains most commonly affect the ligaments on the outside of the ankle (inversion sprain). The lateral sprain (the most common ankle injury) accounts for 85% of all ankle sprains. After an inversion injury, the lateral ligaments are stretched or torn, usually from anterior to posterior.

The Chatillon dynamometer can be used to measure the force resistance of the ankle as part of a rehabilitation program for a lateral ankle sprain.

During this test, the subject may sit upright with their foot placed flat on the floor. The dynamometer is placed along the inside of the foot. The subject isolates the ankle and rotates the top of the foot in an inward motion as resistance is applied.

The Chatillon dynamometer will measure the instantaneous resistance (force) or measure the average resistance (force) over a specified test period.
