Frozen shoulder (adhesive capsulitis)

Progressive shoulder stiffness and pain that follows a freeze–thaw course.

Overview

Frozen shoulder is a painful, progressive loss of shoulder movement caused by inflammation and tightening of the joint capsule. It typically passes through painful, stiff and recovery phases over many months to a couple of years.

Symptoms

  • Gradual onset of shoulder pain
  • Progressive loss of movement in all directions
  • Marked loss of external rotation
  • Night pain in the early phase

Causes

  • Often idiopathic
  • Associated with diabetes and thyroid disease
  • Following a period of shoulder immobilisation

Treatment

  • Pain management in the painful phase
  • Range-of-motion and stretching as tolerated
  • Strengthening as movement returns
  • Injection or specialist referral if severe
