Injuries that occur over a period of time, with repeated movement causing micro trauma, finally leading to injuries is referred as Overuse Injury. Such as- repetitive backhand stroke in tennis may lead to tennis elbow, i.e. Lateral Epicondylitis. These conditions are different from sudden injuries like sprained ankle, which occurs in one go.
Overuse Injury can affect any musculoskeletal structure like-
Tendons: Tennis elbow, supraspinatus tendonitis, Achilles tendonitis etc;
Bursa: Suprapatellar bursitis, subarachnoid bursitis etc;
Periosteum: shin splints;
Bone: stress fractures;
Signs of Overuse Injury
Swelling may or may not present;
Local temperature is raised;
Tenderness/ pain on touch;
Loss of function or difficulty in performing activity effectively.
These signs may be unnoticeable in the beginning stage, but, often the first sign is stiffness/ soreness especially in the morning which may disappear after warm-up. Repetition of similar activity may continue to damage the tissue and the pain may now present through and post warm-up and may even get worse after activity is finished.
So we may conclude the following four stages of overuse injury:
1. Discomfort that disappears during warm-up;
2. Discomfort that may disappear during warm-up but reappears at the end of activity;
3. Discomfort that gets worse during the activity;
4. Pain or discomfort all the time.
If physiotherapy is started at the Stage 1, patient can continue activity as long as the injury does not worsen.
If patient presents at Stage 2, patient may continue activity at a modified pain-free level while being treated. Treatment must continue until completely healed.
At Stage 3, all physical activity that produces pain must be immediately stopped. Only after completely being symptom free and with physiotherapy supervision one can be allowed to return to activity.
If the injury progresses to Stage 4, similar procedure should be followed as Stage 3.
Causes of Overuse Injury
- Inadequate muscle strength and endurance;
- Lack of core stability;
- Muscle imbalance;
- Biomechanical faults or malalignment like flat feet, maltracking of patella etc;
- Training errors, this is most common of all other causes;
- Faulty technique;
- Incorrect equipment.
Prevention Against Overuse Injury
Overuse injuries can be prevented by following certain norms while exercising/ playing or while doing physical strenuous activity. These includes-
- Proper warm-up and cool-down before and after all exercise;
- Use of proper equipment (e.g. well supported jogging shoes, adequate size, weight and grip of a racquet to one’s level of play);
- Progress at a rate no faster than 10% per week (distance, speed, weight, etc);
- Practice and concentrate on correct technique;
- Respect pain, which signals that something is wrong. Early identification and treatment allows continuation of physical activity.
- Identify and correct the cause of pain or discomfort;
- Ensure complete rehabilitation post injury, e.g. Tendonitis in one shoulder may result into tendonitis in other shoulder because of overuse of that shoulder.
COMMON OVERUSE INJURIES INCLUDES
The most important steps in managing overuse injury are-
- Removal of causative agents;
- Reduce pain and inflammation;
- Careful return to activities as the symptoms reduces.
An expert physiotherapist will carefully assess and guide necessary measures to be taken to treat overuse injuries.
