For the management of shoulder impingement syndrome (SIS), exercise was found to be superior to control interventions; specific exercise showed greater effectiveness than generic exercise.

Ultrasound-guided corticosteroid injections, NSAIDs and manual therapy were superior to non-guided injections and placebo, respectively. Manual therapy was superior to exercise in short follow-up periods.

ECSWT, laser and tape were superior to sham treatment. It remains unclear how these treatments compare to exercise.
