According to the severity of the condition, the wrists were classified into a mild group (38 wrists), a moderate group (30 wrists), and a severe group (42 wrists). During the same period, 25 healthy controls were recruited, comprising 50 healthy wrists. All patients and healthy volunteers underwent high-frequency ultrasound examination to measure the vertical displacement of the median nerve relative to the transverse carpal ligament during wrist dorsiflexion/palmar flexion, as well as the changes in the cross-sectional area (CSA) of the median nerve at the pisiform level. All CTS patients also underwent electrophysiological testing to measure the sensory conduction velocity (SCV), sensory latency, and sensory nerve action potential (SNAP) amplitude of the median nerve.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;In the carpal tunnel syndrome (CTS) group, the distance from the proximal end of the median nerve to the transverse carpal ligament [2.59(2.24, 2.79) mm], the distance from the distal end to the transverse carpal ligament [2.11 (1.82, 2.31) mm], and the cross-sectional area[ 0.16(0.12, 0.19) cm&lt;sup&gt;2&lt;/sup&gt;] during palmar flexion were all significantly lower than those during wrist dorsiflexion [2.62(2.27, 2.82) mm, 2.14(1.85, 2.34) mm, and 0.18(0.14, 0.21) cm&lt;sup&gt;2&lt;/sup&gt;, respectively (&lt;i&gt;P&lt;/i&gt;&lt;0.01)]. Similarly, in the control group, the distance from the proximal end of the median nerve to the transverse carpal ligament [2.88(2.54, 3.38) mm], the distance from the distal end to the transverse carpal ligament[2.33(1.99, 2.75) mm], and the cross-sectional area [0.06(0.02, 0.09) cm&lt;sup&gt;2&lt;/sup&gt;] during palmar flexion were all significantly lower than those during wrist dorsiflexion[2.94(2.60, 3.44) mm, 2.39(2.05, 2.84) mm, and 0.10(0.07, 0.12) cm&lt;sup&gt;2&lt;/sup&gt;, respectively (&lt;i&gt;P&lt;/i&gt;&lt;0.01)].
