The clinical cluster of pain, limited range of motion and dysfunction usually associated to shoulder problems is frequently accompanied by nocturnal pain in patients with rotator cuff disease, adhesive capsulitis, and calcific tendinitis and may aggravate the shoulder disorder. Night pain and poor quality of sleep influence the variable perceived shoulder pain and shoulder function, affecting the wellbeing of patients and influencing the bio psychosocial aspect. A relationship exists between the severity of sleep disturbance in proportion to the intensity of the shoulder pain and shoulder dysfunction.
