AC Joint Sprain

Tennis elbow is an injury to the extensor tendons in the forearm. Despite the name, only a small amount of these injuries actually happen playing tennis. It is most commonly associated with repetitive arm movement, heavy lifting, prolonged computer use and repetitive vibration. Along with sports people, it is commonly seen in manual workers such as electricians, carpenters and gardeners. Injury occurs due to an overload of the tendon tissue which can result in inflammation of the tendon, microscopic tears in the tendon or degeneration of the tendon tissue.

Symptoms

1. Pain in the outside of the elbow which may radiate into the forearm or fingers
2. Movements such as gripping or rotating the forearm may increase pain
3. Tenderness to touch the outside of the elbow
4. Weakness when gripping and using forearm muscles
5. Neck pain and nerve irritation may also be associated with the condition

Treatments

There are various treatment options for tennis elbow, your physiotherapist will assess and use a combination of treatments depending on what is best suited to you.

Evidence suggests tendons respond best to beginning with eccentric exercises that strengthen the muscle while lengthening it [1] providing a greater reduction in pain and increase in strength compared to concentric exercises [2]. Once pain is controlled and strength increased, exercises can then be progressed on to concentric strengthening and finally functional or sports specific exercises including plyometric type exercises [3]. It is important to strengthen the full kinetic chain when rehabilitating the elbow so shoulder, scapula and core exercises will often be included in treatment [3] [4]. There is some evidence to suggest that stretching the extensor muscles can have a short-term effect on pain, especially when combined with eccentric exercise [1] [4].

Manual therapy such as joint mobilisation and soft tissue release can additionally provide short term pain relief and facilitate exercises [1][5]. Similarly, acupuncture/dry needling can provide short term benefits for 2-8 weeks which may facilitate treatment and improve outcomes [4] [6]. Kineso taping has also been found to reduce pain in tennis elbow, especially when used in combination with exercise [7][5].

Furthermore, intense therapeutic ultrasound can effectively reduce pain and increase function in chronic tendinopathies [8] and it is believed that using a combination of ultrasound and exercise has a better outcome than exercise alone [5].

It is clear from the evidence that a combination of strengthening and additional treatment modalities is the best approach to treat tennis elbow.
