Purpose

Survivors of breast cancer (BC) on the non-dominant side have more persistent deficits than those with cancer on the dominant limb. What is not known is whether those with BC use their involved upper limbs more, less, or at the same level as women without BC. Accelerometer use offers a quantifiable method to measure activity levels of upper limbs. The purpose of this study was to quantify the activity levels of the non-dominant involved limb among survivors of BC and compare these values to their dominant limb, as well as the non-dominant limb of a control group.

Methods

Participants (n = 30) were women with unilateral BC on the non-dominant limb, diagnosed between 6 and 24 months prior to data collection, and a matched healthy group of women as controls. Participants completed the following questionnaires: medical and demographics, Brief Fatigue Inventory, Brief Pain Inventory – Short form, Disabilities of the Arm, Shoulder and Hand (DASH), and Beck Depression Index. Participants wore an accelerometer on each wrist during waking hours for 7 days. Arm activity was measured using vector magnitude activity counts extracted from the accelerometers.

Results

There were no significant differences in total vector magnitude activity counts between groups for either limb. Within group dominant to non-dominant comparison was significantly different (p ≤ 0.001). No significant difference in pain was present but significant differences for fatigue (p = 0.002), depression (p = 0.004), and DASH scores (p = 0.035) were present.

Conclusions

Women with non-dominant BC use their involved limb similar to healthy controls but less than their dominant limb.

乳腺癌幸存者与健康对照者手臂活动的定量比较：加速度计的使用。

目的

非优势侧乳腺癌（BC）的幸存者比优势肢带癌症的幸存者具有更多的持续性缺陷。尚不知道患有BC的女性与没有BC的女性相比，其受累的上肢是更多，更少还是处于相同水平。加速度计的使用提供了一种可量化的方法来测量上肢的活动水平。这项研究的目的是量化BC幸存者中非优势肢体的活动水平，并将这些值与他们的优势肢体以及对照组的非优势肢体进行比较。

方法

参加者（n  = 30）是在非优势肢体上单侧BC的女性，在数据收集之前的6至24个月之间被诊断出，并有一组健康的女性作为对照。参与者完成了以下调查问卷：医疗和人口统计学，疲劳简要清单，疼痛简短清单（简短形式），手臂，肩膀和手部残疾（DASH）以及贝克抑郁指数。参与者在醒来7天的时间内每个手腕上都佩戴了加速度计。使用从加速度计提取的矢量幅度活动计数来测量手臂活动。

结果

各肢各组之间的总矢量幅度活动计数没有显着差异。内组显性到非主导比较是显著不同（p  ≤0.001）。疼痛无显着差异，但疲劳（p  = 0.002），抑郁（p  = 0.004）和DASH评分（p  = 0.035）存在显着差异。

结论

BC非优势女性的受累肢体与健康对照者相似，但少于优势肢体。
