Pain, motion and function comparison of two exercise protocols for the rotator cuff and scapular stabilizers in patients with subacromial syndrome

Eccentric exercise (EE)
was shown to be an effective treatment in tendinopathies. However, the evidence
of its effectiveness in subacromial syndrome (SS) is scarce. Moreover, consensus
has not been reached on whether best results for SS are obtained by means of EE
with or without pain.
The purpose of this is to compare the
effect on pain, active range of motion (AROM), and shoulder function of an
exercise protocol performed with pain <40 mm Visual Analog Scale (VAS) and
without pain, in patients with SS. METHODS: Twenty-two subjects (mean age: 59
years [Q1 = 48.50-Q3 = 70], 54.5% women) were randomized into a not-painful EE
group (NPEE; G0: n = 11) and a painful EE group (PEE; G1: n = 11). The
intervention lasted 4 weeks. Pain was recorded using VAS; AROM was measured using
a goniometer; and shoulder function using the modified Constant-Murley Score
(CMS) before and after intervention. RESULTS: All dependent variables improved
significantly in both groups (P < .05): NPEE VAS median: pretest = 55.0 posttest
= 28.0; CMS median: pretest = 36.0 posttest = 65.0. PEE VAS median: pretest =
37.0 posttest = 12.0; CMS median: pretest = 35.0 posttest = 59.0. The comparison
between groups showed no significant differences, with small effect size values
(VAS = 0.09; CMS = 0.21; AROM = 0.12-0.43). DISCUSSION: In contrast to the
previous findings, our results suggest that PEE do not add benefit in SS patients
compared to NPEE. CONCLUSION: Our results suggest that both interventions are
effective in terms of pain, function, and shoulder AROM. Furthermore, PEE does
not provide greater benefits. Further studies are needed with long-term follow-up
to reinforce these results.
