OBJECTIVE: To evaluate the effect on pain intensity and function of an exercise
concept focusing on specific eccentric strength training of the rotator cuff in
patients with subacromial impingement syndrome.
Single-subject research
design with baseline and treatment phases (AB design). Home-based
training programme supervised and supported by visits to physiotherapy clinic.
SUBJECTS: Ten patients, mean (SD) age 54 (8.6) years, symptom duration 12 (9.1)
months. Daily eccentric strengthening exercises of the rotator cuff
during 12 weeks. MAIN MEASURES: Primary outcome measures: Pain intensity,
assessed with a visual analogue scale, and function, using the Patient-Specific
Functional Scale. Secondary outcome measures: Shoulder function evaluated with
the Constant score, and shoulder-related quality of life evaluated with the
Western Ontario Rotator Cuff Index. RESULTS: Pain intensity decreased
significantly in eight of the ten subjects. Function improved significantly in
all ten subjects. Constant score increased in nine subjects and Western Ontario
Rotator Cuff Index increased in seven subjects. Mean Constant score for the whole
group increased significantly from 44 to 69 points (P = 0.008). Mean Western
Ontario Rotator Cuff Index increased from 51 to 71%
(P = 0.021). CONCLUSION: A
12-week eccentric strengthening programme targeting the rotator cuff and
incorporating scapular control and correct movement pattern can be effective in
decreasing pain and increasing function in patients with subacromial impingement
syndrome. A randomized controlled trial is necessary to provide stronger evidence
of the method.
