Shoulder strength assessment plays an important role in the clinical examination of the shoulder region. Eccentric strength measurements are of special importance in guiding the clinician in injury prevention or return-to-play decisions after injury.
To examine the absolute and relative reliability and validity of a standardized eccentric strength-measurement protocol for the glenohumeral external rotators.
Descriptive laboratory study.
Testing environment at the Department of Rehabilitation Sciences and Physiotherapy of Ghent University, Belgium.
Twenty-five healthy participants (9 men and 16 women) without any history of shoulder pain were tested by 2 independent assessors using a handheld dynamometer (HHD) and underwent an isokinetic testing procedure.
INTERVENTION(S): The clinical protocol used an HHD, a DynaPort accelerometer to measure acceleration and angular velocity of testing 30°/s over 90° of range of motion, and a Biodex dynamometer to measure isokinetic activity.
MAIN OUTCOME MEASURE(S): Three eccentric strength measurements: (1) tester 1 with the HHD, (2) tester 2 with the HHD, and (3) Biodex isokinetic strength measurement.
The intratester reliability was excellent (0.879 and 0.858), whereas the intertester reliability was good, with an intraclass correlation coefficient between testers of 0.714. Pearson product moment correlation coefficients of 0.78 and 0.70 were noted between the HHD and the isokinetic data, showing good validity of this new procedure.
Standardized eccentric rotator cuff strength can be tested and measured in the clinical setting with good-to-excellent reliability and validity using an HHD.
肩部力量评估在肩部区域的临床检查中起着重要作用。离心力量测量对于指导临床医生进行损伤预防或受伤后恢复运动的决策尤为重要。
检验用于盂肱关节外旋肌的标准化离心力量测量方案的绝对可靠性、相对可靠性和有效性。
描述性实验室研究。
比利时根特大学康复科学与物理治疗系的测试环境。
25名无肩部疼痛病史的健康参与者（9名男性和16名女性），由2名独立评估者使用手持测力计（HHD）进行测试，并接受等速测试程序。
临床方案使用了HHD、用于测量30°/秒测试加速度和角速度的DynaPort加速度计（运动范围为90°）以及用于测量等速活动的Biodex测力计。
三次离心力量测量：（1）评估者1使用HHD进行测量，（2）评估者2使用HHD进行测量，（3）Biodex等速力量测量。
评估者内可靠性极佳（分别为0.879和0.858），而评估者间可靠性良好，评估者之间的组内相关系数为0.714。HHD与等速数据之间的Pearson积矩相关系数分别为0.78和0.70，表明该新程序具有良好的有效性。
在临床环境中，使用HHD可以对标准化的肩袖离心力量进行测试和测量，可靠性和有效性良好至极佳。
