Gait retraining is a method used to prevent and rehabilitate injuries to the leg, knee or hip that occur from walking or running. The goal of this technique is to correct body mechanics for a better stride and to lessen stress on the joints and soft tissue. It is most commonly used to reduce joint wear and tear for runners and to help older adults recover from falls or stroke.

During gait retraining, sensors placed on the legs convey real-time, three-dimensional images to a computer where gait problems can be identified. The client uses the 3-D imagery to practice and learn corrected body mechanics to prevent future injury. Gait retraining is often coupled with strengthening and stretching exercises in order to overcome muscular imbalances.
