The shoulder is a joint, where movement has to be precisely coordinated, as it is a muscle-stabilized joint (with a big ball and small socket as joint partners) (Muffalli, 2012).
Rotator cuff tendinopathy refers to dysfunction within one or more of these tendons. Patients present themselves with reduced range of movement, pain and weakness in the shoulder (Wolfson et al., 2010). Poor shoulder mechanics can rub the tendon against the edges of the bony space resulting in microscopic tears within the substance of the tendon.
In general mechanical and biological factors are involved when it comes to rotator cuff pathologies; usually a single factor is not sufficient to determine the disease on its own (Muffalli and Furia, 2012). In the British population a predominance in women with 6.1% compared to 4.5% in men is shown. The most commonly involved tendon is that of the supraspinatus muscle. This muscle helps to raise the arm into the air. Its tendon passes through a small space between the top of the arm bone and the point of the shoulder. In this space the tendon is susceptible to ‘wear and tear’.
Management of this condition involves Physiotherapy to regain strength and mobility to the shoulder complex.
