Table 3 Electrophysiologic outcomes at baseline and 3 month after the procedure in two groups

From: Ultrasound-guided needle release of the transverse carpal ligament with and without corticosteroid injection for the treatment of carpal tunnel syndrome

  Group A (N = 18 wrists) Group B (N = 21 wrists)
  Baseline Posprocedure Baseline Postprocedure
DML(ms) 4.73 ± 0.43 4.1 ± 0.37a 4.71 ± 0.52 4.4 ± 0.87a,b
SCV(m/s) 36.85 ± 1.46 42.63 ± 2.60a 37.16 ± 1.07 39.02 ± 1.07a,b
  1. a, vs baseline, P < 0.05; b, vs Group A; Group A, ultrasound-guided needle release of the transverse carpal ligament plus corticosteroid injection; Group B, single ultrasound-guided needle release of the transverse carpal ligament; DML, distal motor latency; SCV, sensory conduction velocity
