To evaluate the inter-rater and intra-rater reliability of the hand held dynamometer in measuring muscle strength in people with interstitial lung disease (ILD).
Test retest reliability of hand-held dynamometry for elbow flexor and knee extensor strength between two independent raters and two testing sessions.
Physiotherapy department within a tertiary hospital.
Thirty participants with ILD of varying aetiology were included. Twenty participants completed the inter-rater reliability protocol (10 idiopathic pulmonary fibrosis, mean (SD) age 73 (10) years, 11 male) and 21 participants completed the intra-rater reliability protocol (10 idiopathic pulmonary fibrosis, mean age 71 (10) years, 11 male).
Mean muscle strength (kg). Agreement between the two raters and testing sessions was analyzed using Bland-Altman plots and reliability was estimated using intraclass correlation coefficients (ICC).
For elbow flexor strength there was a mean difference between raters of -0.6kg (limits of agreement (LOA) -5.6 to 4.4kg) and within raters of -0.3kg (LOA -2.8 to 2.3kg). The ICCs were 0.95 and 0.98, respectively. For knee extensor strength there was a mean difference between raters of -1.5kg (LOA -6.9 to 3.9kg) and within raters of -0.7kg (LOA -3.9 to 2.4kg). The ICCs were 0.95 and 0.97, respectively.
Hand-held dynamometry is reliable in measuring elbow flexor and knee extensor strength in people with ILD.
评估手持测力计测量间质性肺疾病(ILD)患者肌肉力量时的评分者间信度和评分者内信度。
对两名独立评分者以及两个测试阶段的肘部屈肌和膝部伸肌力量进行手持测力计测试-重测信度研究。
一家三级医院的理疗科。
纳入30名病因各异的ILD患者。20名参与者完成了评分者间信度方案(10例特发性肺纤维化,平均(标准差)年龄73(10)岁,11名男性),21名参与者完成了评分者内信度方案(10例特发性肺纤维化,平均年龄71(10)岁,11名男性)。
平均肌肉力量(千克)。使用Bland-Altman图分析两名评分者和测试阶段之间的一致性,并使用组内相关系数(ICC)估计信度。
对于肘部屈肌力量,评分者间的平均差异为-0.6千克(一致性界限(LOA)为-5.6至4.4千克),评分者内的平均差异为-0.3千克(LOA为-2.8至2.3千克)。ICC分别为0.95和0.98。对于膝部伸肌力量,评分者间的平均差异为-1.5千克(LOA为-6.9至3.9千克),评分者内的平均差异为-0.7千克(LOA为-3.9至2.4千克)。ICC分别为0.95和0.97。
手持测力计在测量ILD患者的肘部屈肌和膝部伸肌力量方面具有可靠性。
