Median nerve neurophysiology data of patients with CTS pre- and post-surgery

Surgery group
Healthy controls
Pre Post P-value Baseline P-value (HC-pre) P-value (HC-post)
SNAP, μV 2.8 [8.2] 6.0 [5.5] 0.004 13.5 [11.1] <0.0001 <0.0001
Sensory NCV, m/s 34.5 [7.9] 41.5 [6.15] <0.0001 50.2 [6.9] <0.0001 <0.0001
Distal motor latency, ms 5.4 [1.8] 4.3 [1.0] <0.0001 3.1 [0.7] <0.0001 <0.0001
CMAP, mV 4.1 [4.1] 5.2 [4.7] 0.299 7.7 [2.9] 0.001 0.005
Delay ulnar-median 1.6 [1.5] 0.8 [0.4] <0.0001 0.2 [0.2] <0.0001 <0.0001

Data are presented as median [IQR]. CMAP = compound motor action potential; delay ulnar-median = delay between the motor potentials for dorsal interossei (ulnar nerve) and lumbricals (median nerve) measured over an 8 cm wrist segment; HC = healthy controls; NCV = nerve conduction velocity; SNAP = sensory nerve action potential.

P-values that were significant following Benjamini-Hochberg correction are highlighted in bold.
