Where it strikes
Medical treatment
- Steroid injection early — the best evidence of the lot, and it fades mixed evidence
- Physiotherapy — helps range, does not shorten the illness mixed evidence
- Hydrodilatation mixed evidence
- Manipulation under anaesthesia mixed evidence
- Arthroscopic capsular release — for the few still stuck after a year; most resolve by themselves in one to three years mixed evidence
Natural & lifestyle
- Gentle daily range-of-motion
- heat before stretching
- blood sugar control
- patience — it does resolve
Emerging & experimental
- Ultrasound-guided hydrodilatation protocols
- suprascapular nerve block
