Abstract

<p>The aim of this study was to investigate the effects of the factors that influence the improvement in motor function at 6 months after arthroscopic rotator cuff repair (ARCR) on the improvement in the disabilities of the arm, shoulder, and hand (DASH) score at 1 year postoperatively. Methods: A total of 83 patients who underwent ARCR and postoperative rehabilitation were included in the study. The patients were classified into two groups according to whether or not their DASH scores improved from the preoperative period to 1 year postoperatively. The effect of improvement in shoulder range of motion, strength, and pain, as well as the presence or absence of re-tear at 6 months after surgery on improvement in DASH scores at 1 year postoperatively was examined using logistic regression analysis. Results: Logistic regression analysis revealed that improvement in shoulder abduction strength, and pain, as well as the presence or absence of re-tear were all significantly related to the improvement in DASH scores at 1 year postoperatively. Furthermore, the cut-off values calculated using receiver operating characteristic curve analysis were 0.25 N/kg for shoulder abduction strength improvement and 2.00 for pain reduction. Conclusion: Results suggest that improvement in shoulder abduction strength, pain reduction, and absence of re-tear at 6 months after surgery are important for improving the DASH score 1 year after surgery.</p>
