Fatigue and decreased muscle strength are the prominent ones that can account for decreased upper extremity function. Therefore, this study aimed to explore the potential contributors to the upper extremity function of BCS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 100 BCS were included. Handgrip strength (HGS) was assessed with a dynamometer while fatigue and self\u2010reported upper extremity function were assessed with the Fatigue Severity Scale (FSS), Disabilities of Arm, Shoulder, and Hand Questionnaire (DASH), respectively. To control the potential confounding effect of the handedness, the mean value of HGS was used in the regression model.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>HGS was found to be significantly higher on the right side compared to the left side (22.71\u00a0\u00b1\u00a03.51\u00a0kg vs. 21.45\u00a0\u00b1\u00a03.66\u00a0kg, <jats:italic>t<\/jats:italic>\u00a0=\u00a05.328, <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001).

The multivariate linear regression analysis showed that a total of 26.9% of the cumulative variance in DASH is explained by the mean HGS, FSS, and body mass index (BMI) (F (4,95)\u00a0=\u00a011.793, <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001, <jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>\u00a0=\u00a00.269, Cohen's <jats:italic>f<\/jats:italic><jats:sup>2<\/jats:sup>:0.54). There were no significant effects and\/or interactions of any clinical features of BCS on DASH. FSS and DASH also significantly correlated with each other (<jats:italic>r<\/jats:italic>\u00a0=\u00a00.49, <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>This study showed that HGS shows itself as a significant outcome measure to predict upper extremity function in BCS.
