Specific exercises for subacromial pain: Good results maintained for 5 years

Background and purpose - We have previously shown that specific exercises reduced the need for surgery in subacromial pain patients at 1-year follow-up. We have now investigated whether this result was maintained after 5 years and compared the outcomes of surgery and non-surgical treatment. Patients and methods - 97 patients were included in the previously reported randomized study of patients on a waiting list for surgery. These patients were randomized to specific or unspecific exercises. After 3 months of exercises the patients were asked if they still wanted surgery and this was also assessed at the present 5-year follow-up. The 1-year assessment included Constant-Murley score, DASH, VAS at night, rest and activity, EQ-5D, and EQ-VAS. All these outcome assessments were repeated after 5 years in 91 of the patients. Results - At the 5-year follow-up more patients in the specific exercise group had declined surgery, 33 of 47 as compared with 16 of 44 (p = 0.001) in the unspecific exercise group. The mean Constant-Murley score continued to improve between the 1- and 5-year follow-ups in both surgically and non-surgically treated groups. On a group level there was no clinically relevant change between 1 and 5 years in any of the other outcome measures regardless of treatment. Interpretation - This 5-year follow-up of a previously published randomized controlled trial found that specific exercises reduced the need for surgery in patients with subacromial pain. Patients not responding to specific exercises may achieve similar good results with surgery. These findings emphasize that a specific exercise program may serve as a selection tool for surgery.
