EFFECTIVENESS: 4/5

Several studies have shown manipulation can be helpful for shoulder pain-sprain/strain. However, research specifically related to sprain/strain in isolation is minimal. There are many different types of shoulder pain-sprain/strain, and while manipulation may help some patients with different types of shoulder pain-sprain/strain, it is not effective for all shoulder pain-sprain/strain sufferers, including pain associated with nerve-involvement. Several studies however have shown that some patients who receive manipulation do better in the short and long term compared to usual medical care.
Bottom line: there is fair evidence that manipulation and mobilization is effective for some types of shoulder pain-sprain/strain, but more research needs to be done.
Additionally, there is some evidence related to manipulation/mobilization related to conditions other than sprain/strain, including: rotator cuff tear, adhesive capsulitis. Research is poor as it relates to neurogenic shoulder pain and osteoarthritis. More current research suggests that manipulation was at least as effective as steroid injections for frozen shoulder.[i]
Of interest: One recent study demonstrated that manipulation performed by Doctors of Chiropractic is the most frequently requested alternative medicine approach for chronic tension-type shoulder pain-sprain/strain, and slightly more than 40% reported improvement with the treatment. [ii] There are many other papers related to the treatment of shoulder sprain/strain using manipulation and/or mobilization. [iii], [iv], [v], [vi], [vii], [viii], [ix]
