 Exercise Better Than Shockwave in Easing Chronic Shoulder Pain
Supervised exercise helps ease chronic shoulder pain better than sound shockwave treatment, a new study suggests.
In the study, published in the online British Medical Journal, team of researchers based in Oslo, Norway compared the effectiveness of radial extracorporeal shockwave treatment (low to medium energy impulses delivered into the tissue) with supervised exercises in patients with shoulder pain.

The research involved 104 men and women aged between 18 and 70 years.

Participants were randomised to receive either radial extracorporeal shockwave treatment (one session weekly for four to six weeks) or supervised exercises (two 45 minute sessions weekly for up to 12 weeks).

Both groups were similar at the start of the study with regard to age, education, dominant arm affected and pain duration.

All patients were monitored at six, 12 and 18 weeks and were advised not to have any additional treatment except analgesics (including anti-inflammatory drugs) during the follow-up period. Pain and disability were measured using a recognised scoring index.

After 18 weeks, 32 of patients in the exercise group achieved a reduction in shoulder pain and disability scores compared with 18 in the shockwave treatment group.

More patients in the exercise group returned to work, while more patients in the shockwave treatment group had additional treatment after 12 weeks, suggesting that they were less satisfied.

The authors conclude: "Supervised exercises were more effective than radial extracorporeal shockwave treatment for short term improvement in patients with subacromial shoulder pain."
