There is limited evidence regarding the combined effect of exercise and compression garment on breast cancer-related lymphedema (BCRL). Therefore, we investigate the effect of low-intensity resistance training alone or in combination with a compression garment on lymphedema volume, self-reported lymphedema symptoms, and shoulder mobility and function. A total of 60 women with unilateral BCRL were randomly assigned to low-intensity resistance exercises (Rex group, n = 30) or exercises and compression garment (Rex-Com-group, n = 30). Both groups take part in exercises program consisted of 10-12 repetitions at 50 to 60% of one repetition maximum (IRM), three times weekly, for 8 weeks. The primary outcome was lymphedema volume determined by percentage reduction of excess limb volume (ELV). Secondary outcomes were lymphedema symptoms (pain, heaviness, and tightness) and shoulder mobility and function using the disabilities of the arm, shoulder, and hand (DASH) questionnaire. All measurements were standardized and performed before (week 0, W0), after the intervention (week 8, W8), and at follow-up (week 12, W12). A significant reduction in percentage of ELV (p < 0.01), pain severity (p < 0.05), a sensation of heaviness (p < 0.05) and tightness (p < 0.001), and improvement in shoulder range of motion (p < 0.05) and function on DASH scores (p < 0.05) were observed at W8 and W12 in both groups. However, no between-group differences were observed over time. These findings suggest that low-intensity resistance training, irrespective of garment use, can effectively reduce limb volume and lymphedema symptoms, and increase shoulder mobility and function.
关于运动和压缩衣对乳腺癌相关淋巴水肿（BCRL）的综合影响，证据有限。因此，我们研究了单独进行低强度抗阻训练或结合使用压缩衣对淋巴水肿体积、自我报告的淋巴水肿症状以及肩部活动度和功能的影响。共有 60 名单侧 BCRL 女性患者被随机分配到低强度抗阻运动（Rex 组，n = 30）或运动和压缩衣组（Rex-Com 组，n = 30）。两组均参加了为期 8 周的每周 3 次的运动方案，包括 10-12 次重复，重复次数为 1 次最大重复次数（IRM）的 50-60%。主要结局是通过多余肢体体积（ELV）减少的百分比确定的淋巴水肿体积。次要结局是使用手臂、肩部和手残疾问卷（DASH）评估淋巴水肿症状（疼痛、沉重感和紧绷感）和肩部活动度和功能。所有测量均在标准化后进行，分别在干预前（第 0 周，W0）、干预后（第 8 周，W8）和随访时（第 12 周，W12）进行。两组患者的 ELV 百分比（p < 0.01）、疼痛严重程度（p < 0.05）、沉重感（p < 0.05）和紧绷感（p < 0.001）均显著降低，肩活动度（p < 0.05）和 DASH 评分的功能（p < 0.05）均显著提高。然而，两组之间在不同时间点均未观察到差异。这些发现表明，低强度抗阻训练，无论是否使用服装，均可有效减少肢体体积和淋巴水肿症状，并增加肩部活动度和功能。
