Transverse sliding patterns of the median nerve.

<p>Representative fitted curves indicating the various transverse sliding patterns of the median nerve during fingers flexion and extension movements among a normal subject, a mild-CTS patient, and a severe-CTS patient. The dots, triangles, and diamonds represent the cumulative lateral displacements at different acquisition times and the intersecting lines indicate the fitted curves for the different subgroups, respectively. Normal, Mild, and Severe indicate normal subjects, mild-CTS and severe-CTS patients.
