Rotator Cuff Tendinopathy

The rotator cuff is a group of four muscles surrounding the shoulder blade and humeral head that provide mobility and stability of the shoulder joint. Rotator cuff tendinopathies are defined as pain and weakness of the shoulder muscles due to an overload of the tissues. Occupations involving awkward postures, repetitive arm movements, overhead movements, heavy lifting, static postures and lack of rest can increase the likeliness of developing a shoulder injury. Extrinsic factors can compress the rotator cuff tendons such as decreased space in the shoulder joint, alterations in the scapular kinematics, postural abnormalities or rotator cuff weaknesses. Intrinsic factors such as age, tendon degeneration, overuse and trauma to the shoulder can additionally cause rotator cuff injuries.

Symptoms

1. Shoulder pain, usually a dull ache
2. Tenderness in the shoulder joint
3. Pain increased with overhead reaching, reaching behind the back, lifting and sleeping on the affected side.
4. Weakness of the shoulder
5. Reduced range of movement, particularly elevating the arm forwards or to the side.

Treatments

Strengthening exercises are key to recovering from a rotator cuff tendinopathy [1]. Usually they will begin with isometric (static) strengthening exercises which are effective at reducing and controlling pain [2]. After pain is controlled, more advanced exercises can begin. Range of motion exercises may be needed if shoulder mobility is reduced [1] [3] [4]. Massage and dry needling can be effective at releasing off tight muscles and preparing tissue for mobilisation and strengthening [5][6]. Additionally, postural retraining and increasing upper back mobility has been found to have a positive impact on reducing symptoms and increasing shoulder mobility [7].
