Resumen
GUTIERREZ-ESPINOZA, H et al. Effectiveness of adding posterior capsule stretching after an exercise program in patients with subacromial impingement syndrome: a randomized clinical study. Rev. Soc. Esp. Dolor [online]. 2023, vol.30, n.3, pp.168-177. Epub 04-Mar-2024. ISSN 1134-8046. https://dx.doi.org/10.20986/resed.2023.3927/2021.
Objective:
To determine the clinical effectiveness of adding the exercise of "sleep-stretch" to a specific exercise program in patients with subacromial impingement syndrome (SIS).
Design:
Randomized controlled trial, single-blinded.
Methods:
Sixty-four patients with clinical and imagenologic diagnosis of SIS were prospectively recruited, who were randomly allocated to two groups. The control group (n = 32) received a 12-week exercise program, and intervention group (n = 32) received the same program plus stretching of the posterior capsule. Both groups were assessed at baseline and at the end of the treatment. The primary outcome measure was shoulder function assessed with Constant-Murley questionnaire. Secondary outcomes measures were upper limb function assessed with the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, and pain at rest and movement with visual analog scale (VAS).
Results:
All patients completed the trial. At the end of the treatment, Constant-Murley questionnaire showed a difference of 3 points (p = 0.864), and the DASH questionnaire a difference was 2 points (p = 0.941), both differences were in favor of the intervention group, but they are neither clinically or statistically significant. For the VAS at rest the difference was 0.2 cm (p = 0.096) and the VAS at movement was 0.4 cm (p = 0.378), both differences in pain reduction was greater in the control group.
Conclusion:
In the short term, the addition of a "sleep-stretch" exercise does not provide a clinically or statistically significant benefit with respect to functional improvement or pain reduction in patients with SIS.
