Background: Breast cancer-related lymphedema (BCRL) limits the movements of patients' limbs, which leads to a diminished ability to achieve essential activities of daily living (ADLs). The purpose of this study was to examine the associations between limb volume changes from the baseline before breast cancer surgery and self-reported difficulty in performing ADLs at 12 months following cancer surgery. We hypothesized that a positive association existed between limb volume changes from the baseline and self-reported difficulty in performing ADLs at 12 months following breast cancer surgery.

肢体体积变化和日常生活活动：一项前瞻性研究

背景：乳腺癌相关淋巴水肿 (BCRL) 限制了患者四肢的运动，从而导致实现基本日常生活活动 (ADL) 的能力下降。本研究的目的是检查乳腺癌手术前肢体体积相对于基线的变化与癌症手术后 12 个月时自我报告的 ADL 难度之间的关联。我们假设在乳腺癌手术后 12 个月时，肢体体积相对于基线的变化与自我报告的 ADL 难度之间存在正相关。
