Objectives: The cutaneous silent period (CSP) is a spinal inhibitory reflex related to the stimulation of slow-conducting A-δ fibers. The aim of this study is to evaluate the relationship between spasticity and CSP in patients with stroke. Methods: Twelve stroke patients with hemiplegia were enrolled in the study. The CSP was recorded from the thenar muscles during voluntary contraction. A stimulation train consisting of five noxious electrical shocks was applied to ipsilateral digit II cutaneous nerve to record the CSP. Modified Ashworth scale (MAS) was assessed by an experienced physician. Results: The means of CSP durations were 83.08±18.26 ms and 56.50±9.74 ms on the affected side and the sound side respectively. The CSP duration on the affected side was significantly longer than that of the sound side (p<0.05). The difference of CSP duration between sound side and affected side did not correlate well with the MAS. Conclusion: Our findings showed that the CSP duration on the affected side was longer than that of the sound side and did not correlate well with the MAS. The CSP may be one of the useful tools to evaluate central nervous system. Further study will be needed to find out correlation between the CSP and the spasticity. KCI Citation Count: 0
