Breast cancer survivors (BCS) are often characterized by decreased pressure pain thresholds (PPT), range of motion (ROM) and strength in and around the shoulder affected by the treatment. This intra-rater reliability study was to establish the relative and absolute reliability of PPT's, active ROM and maximal isokinetic muscle strength (MIMS) of the affected shoulder in BCS with persistent pain after treatment.
Twenty-one BCS participated in the study. The PPTs of 17 locations and pain intensity were assessed using a pressure algometer and a numeric rating scale. The ROM was measured using a universal goniometer and MIMS was measured using an isokinetic dynamometer. Relative reliability was estimated using intra class correlation coefficient (ICC), and absolute reliability using standard error of measurement (SEM). Minimum detectable change (MDC) was calculated from SEM.
The ICCs for PPTs ranged from 0.88-0.97, with SEM values ranging from 12.0 to 28.2 kPa and MDC ranging from 33.2 to 78.2 kPa. The ICCs for ROM ranged from 0.66-0.97, with SEM values ranging from 3.0 to 7.5° and MDC ranging from 8.4 to 20.8°. Finally, ICCs for MIMS ranged from 0.62-0.92, with SEM values ranging from 0.03 to 0.07 Nm/Kg FFM and MDC ranging from 0.09 to 0.19 Nm/kg FFM.
The results of this study indicate that PPTs, ROM and MIMS can be measured reliably on the affected shoulder in BCS with pain after treatment. This offer the possibility of using these measures to assess the effectiveness of interventions in this population.
乳腺癌幸存者（BCS）通常表现为治疗影响的肩部压力疼痛阈值（PPT）、活动范围（ROM）和力量降低。本研究旨在确定治疗后持续疼痛的 BCS 中 PPT、受累肩部主动 ROM 和最大等速肌肉力量（MIMS）的相对和绝对可靠性。
21 名 BCS 参与了这项研究。使用压力测痛仪和数字评分量表评估 17 个部位的 PPT 和疼痛强度。ROM 使用通用量角器测量，MIMS 使用等速测力计测量。使用组内相关系数（ICC）评估相对可靠性，使用测量误差（SEM）评估绝对可靠性。从 SEM 计算最小可检测变化（MDC）。
PPT 的 ICC 范围为 0.88-0.97，SEM 值范围为 12.0-28.2kPa，MDC 范围为 33.2-78.2kPa。ROM 的 ICC 范围为 0.66-0.97，SEM 值范围为 3.0-7.5°，MDC 范围为 8.4-20.8°。最后，MIMS 的 ICC 范围为 0.62-0.92，SEM 值范围为 0.03-0.07Nm/KgFFM，MDC 范围为 0.09-0.19Nm/kgFFM。
本研究结果表明，治疗后有疼痛的 BCS 受累肩部的 PPT、ROM 和 MIMS 可可靠测量。这为使用这些措施评估该人群干预措施的有效性提供了可能。
