When we close our eyes, we rely on middle ear balance and these special receptors to keep us upright. If there has been swelling or injury in or around a joint, these tiny receptors get injured and do not recover. You can do certain exercises to get the other receptors to do more, regaining what was lost with the damaged receptors. The loss of position sense puts the joint at further risk of injury because the joint loses stability, like having loose lug nuts on a wheel of a car. You can think of these exercises like balance training.
Some therapists use special manual exercises to get the other receptors working better.
As your range of motion returns, the emphasis of treatment will begin to focus more on strengthening. Good strength will form the basis for safely doing your activities, whether work, sport, or leisure. The training format will continue to advance in intensity with an emphasis on strengthening, closed chain exercises, plyometrics, and progressive running and agilities. Athletes who run, jump, or cut will be progressed in their sport based on the recommendation of their doctor and therapist. You will recheck with your therapist at regular intervals to make sure you are doing these exercises routinely and safely.
