Quantifying the Elasticity Properties of the Median Nerve during the Upper Limb Neurodynamic Test 1

Figure 2

Bland-Altman plots of intra- and interoperator reliabilities for the shear modulus of the median nerve in the neutral posture (NP). Intraoperator reliability (a): the difference in median nerve stiffness between day 1 and day 5 is plotted against mean median nerve stiffness (average of the 2 days for operator A) for each subject. Interoperator reliability (b): the difference in median nerve stiffness between operator A and operator B is plotted against mean median nerve stiffness (average of the 2 operators) for each subject. The continuous lines represent the mean difference, while the dotted lines show the 95% upper and lower limits of agreement.
