摘要
目的目的是评估血液透析期间下肢肌肉手持式测力计测试的内部和相互之间的可靠性:这是一项横断面研究,研究对象包括血液透析至少 3 个月的受试者。手持式测力计对髋部和踝部肌肉力量(N)的测量在4个不同场合进行登记,其中2次由评分者A进行,2次由评分者B进行,以评估评分者内部和评分者之间的可靠性。通过将评分者之间的差异与两位评分者评分的平均值进行比较,绘制布兰德-阿尔特曼图来检验评分者之间的一致性。类内相关系数(ICC)用于评估评分者内部和评分者之间的相对可靠性。绝对信度用最小检测变化(MDC)进行评估:56 名参与者(中位年龄 67 岁)的数据显示出较高至非常高的相对可靠性(ICC 为 0.75 至 0.98)。关于评分者内部的绝对可靠性,髋部肌肉的 MDC90 值在 27.0 至 41.6.5 N(0.14 至 0.26 N/Kg m2)之间,但踝部肌肉的 MDC90 值有所增加。评定者之间的差异值更大。评定者 A 和评定者 B 在两个时间点之间的试验平均差异范围较小(分别为 1.0 - 19.3 N 和 1.3 - 11.4 N)。布兰-阿尔特曼曲线图显示,在踝关节跖屈方面,评分员 A 存在系统性偏差。.结论在透析过程中使用手持式测力计评估髋关节屈曲和外展力量是可靠和安全的。归一化数据可提供更可靠的结果。
Handheld dynamometry testing during dialysis: intra and inter-rater reliability study.
Objective: The aim was to assess the intra and inter-rater reliability of the handheld dynamometry testing of lower limb muscles during hemodialysis.
Methods: This is a cross-sectional study including subjects undertaking hemodialysis for at least 3 months. Handheld dynamometer measurements of hip and ankle muscle strength (N) were registered on 4 different occasions, 2 trials by raters A and 2 by raters B, to evaluate the intra and inter-rater reliability. Bland-Altman plots were constructed to examine the agreement between raters by scoring the difference between raters against the mean of both raters' scores. The intraclass correlation coefficient (ICC) was used to assess relative intra-rater and inter-rater reliability. Absolute reliability was assessed with the minimal detectable change (MDC).
Results: Fifty-six participants (median age, 67 years) data showed high to very high relative reliability (ICCs 0.75 to 0.98). Regarding the intra-rater absolute reliability, MDC90 values ranged from 27.0 to 41.6.5 N (0.14 to 0.26 N/Kg m2) for hip muscles but increased for ankle muscles. Inter-rater values were wider. The mean difference between trials ranged narrowly across the two-time points for raters A (1.0 - 19.3 N) and for raters B (1.3 - 11.4 N). The mean difference between raters ranged from 2.4 to 13.5 N. The Bland-Altman plot revealed a systematic bias for raters A in ankle plantar flexion. .
Conclusions: The assessment of the hip flexion and abduction strength during dialysis with a handheld dynamometer is reliable and safe. Normalized data provides more reliable results.
