Short-latency afferent inhibition in unilateral carpal tunnel syndrome

This is the authors' abstract. We don't add key points for this paper.

Carpal tunnel syndrome (CTS) alters sensory afferent input and may affect cortical sensorimotor processing. We investigated short-latency afferent inhibition (SAI) and its relationship with fine motor performance in 25 patients with unilateral mild-to-moderate CTS. SAI was assessed using individualized interstimulus intervals based on N20 latency. SAI did not differ between the affected and unaffected sides (p = .539). However, higher SAI values, indicating less inhibition, were associated with poorer fine motor performance, with longer Nine-Hole Peg Test completion times on the affected side (p = .042). These findings suggest that individual variation in afferent inhibition may be related to fine motor hand function in CTS.
