Correlation Between Shoulder Impingement and Cervical Proprioception

Shoulder pain is one of the most common complaints in musculoskeletal practice, whether it comes from impingement syndrome or a defect in rotator cuff muscles .Shoulder pain is considered to be the third most common complaint in musculoskeletal practice, with a prevalence of 7% to 34% .Shoulder impingement is a syndrome where there is entrapment of soft tissue through the shoulder joint, with a prevalence of 44% to 65% of all shoulder complaints. Shoulder impingement has multiple causes, whether functional, degenerative, and anatomical and mechanical causes .Shoulder impingement classified to primary and secondary. Secondary impingement is subdivided into internal and external impingement .Proprioception components are joint position sense, kinesthesia, sense of force, sense of change of velocity. joint position sense is our perception of position of the joint or limb it divided to active/passive joint position sense, it means that the person can relocate the position of the joint or the limb to the same position after the joint or limb is moved.the muscle receptor helping in identifying the limb position and movement through changeling in neural signaling in the sensory receptor, giving the neurological control and basis of proprioception to sensory receptors located in the skin, muscles, and joints, so the proprioception is considered to be a loop of feedforward and feedback signals between sensory receptor and the nervous system. sixty eight subjects with shoulder impingement syndrome will be joined to this study.
