Scapular protraction strength can be evaluated using a hand-held dynamometer (HHD). However, it is necessary to measure the reliability of HHD in individuals with shoulder pain and to minimize the limitations related to the evaluator and the low methodological quality cited in previous studies. This study assessed, with methodological enhancement, the intra- and interrater reliability of belt-stabilized HHD in the assessment of scapular protraction strength in individuals with shoulder pain.
Fifty individuals with unilateral symptoms of subacromial pain syndrome (20 men, aged 40.5 ± 15.3 years) were evaluated in two sessions using the belt-stabilized HHD for maximum isometric strength of scapular protraction with the individual in the sitting and supine positions. Reliability values were obtained using the intraclass correlation coefficient with the standard error of measurement (SEM and %SEM) and the minimal detectable change (MDC).
The intra- and interrater HHD reliability were excellent for all measurements ranging from 0.88 to 0.96 (SEM = 2.0-4.0 kg; %SEM 12 to 17; MDC = 6-11 kg).
Belt-stabilized HHD is reliable for the assessment of scapular protraction strength in individuals with subacromial pain syndrome in both the sitting and supine positions.
可以使用手持测力计（HHD）评估肩胛骨前伸力量。然而，有必要测量患有肩部疼痛的个体中 HHD 的可靠性，并最大限度地减少评估者相关的限制和先前研究中提到的低方法学质量。本研究通过方法学改进，评估了肩带稳定的 HHD 在评估肩痛患者肩胛骨前伸力量时的组内和组间可靠性。
在两个会话中，使用肩带稳定的 HHD 评估了 50 名单侧肩峰下疼痛综合征症状的个体（20 名男性，年龄 40.5±15.3 岁）的最大等长肩胛骨前伸力量，个体处于坐姿和仰卧位。使用组内相关系数（ICC）和测量误差（SEM 和 %SEM）以及最小可检测变化（MDC）来获得可靠性值。
在所有测量中，组内和组间 HHD 的可靠性均为优秀，范围从 0.88 到 0.96（SEM=2.0-4.0kg；%SEM 为 12-17；MDC=6-11kg）。
肩带稳定的 HHD 可可靠地评估肩峰下疼痛综合征个体在坐姿和仰卧位时的肩胛骨前伸力量。
