摘要:
      摘要 目的:用新型MyotonPRO数字化肌肉检测仪评估健康成年人腓肠肌肉内外侧头硬度信度研究,对比小腿三头肌内外侧头硬度。 方法:两名经过培训的测试人员A、B分别用新型MyotonPRO对40例健康志愿者双侧腓肠肌内外侧头硬度进行测量,其中测试人员A在5天之后重复测量一次。计算组内相关系数(ICC)和最小检测变化值(MDC),并对利腿侧进行Bland-Altman分析,同时比较利腿与非利腿侧腓肠肌内外侧头硬度的差异性。 结果:测试人员A与测试人员B的评估者间信度ICC两侧均为优秀(ICC=0.94—0.96),测试人员A的重测信度均为好(ICC=0.75—0.87),最小检测变化值为18.3 N/m;Bland-Altman 分析显示,同一测试者与不同测试者之间均有较好的一致性。利腿和非利腿侧腓肠肌肉内外侧头硬度均有显著性差异(P<0.00)。 结论:新型MyotonPRO数字化肌肉检测仪评估健康成年人小腿腓肠肌肉内外侧头硬度信度较高,腓肠肌外侧头硬度比内侧头大。

Abstract:
      Abstract Objective: To investigate the intra and inter-rater reliability of MyotonPRO in assessment of the medial and lateral head stiffness of the gastrocnemius muscle . Method: Forty healthy subjects (male,n=20,female,n=20,total,N=40) were recruited and the medial and lateral head of the gastrocnemius muscle were measured using a novel hand-held MyotonPRO device by two raters. One of the raters performed re-testing 5d later. Reliability was assessed using intra-class correlation coefficients (ICCs) and Bland and Altman analysis. Minimum detectable change (MDC) was calculated in the present study. The medial and lateral head stiffness of the gastrocnemius muscle of the dominant or non-dominant leg were compared in the present study. Result: The inter-rater reliability of the medial and lateral head stiffness of the gastrocnemius muscle was excellent(ICC=0.94-0.96).The intra-rater reliability was good(ICC=0.75-0.87) with 18.3 N/m minimum detectable change(MDC). Examples of Bland and Altman plots showed good agreement. There was significant difference between the medial and lateral head stiffness of the gastrocnemius muscle (P<0.00). Conclusion: The intra and inter-rater reliability of MyotonPRO were good in measuring the medial and lateral head stiffness of the gastrocnemius muscle in healthy subjects. There was significant difference between the medial and lateral head stiffness of the gastrocnemius muscle.
