“…The prolonged CSP latency in patients with DM compared to controls was similar to a previously reported study [11]. The authors in the previous study suggested that the CSP may be a useful method for the early detection of diabetic SFN based on the shorter duration of the CSP in diabetic patients with SFN than the duration in diabetic patients without SFN.…”

“…Only one study has reported delayed CSP in patients with DPN [11]; however, the study analyzed only a few subjects and defined SFN based solely on neuropathic symptoms, regardless of the NCS findings. We performed the current study to evaluate whether or not the CSP is a useful metric to identify SFN, specifically in patients with sensory symptoms, but normal NCS findings.…”

“…Our aim was to set the onset and end cursors in such a way as to ensure the least subjective influence. The onset latencies measured in our study correspond to those of most other studies, 2,5,8,14,[16][17][18][19][20] but are significantly longer than those in the study by Kofler. 5 However, we did observe a probable earlier CSP onset or early dip (e.g., Fig. 2) in most subjects in roughly 20% of the measurements.…”

“…[1][2][3][4][5][6] Measurement of the CSP could have clinical relevance in evaluation of the anatomical integrity of peripheral small myelinated (A-delta) nerve fibers as well as of spinal gray matter in diseases of peripheral nerves and spinal cord. [7][8][9] Thus, CSP is complementary to standard nerve conduction studies and electromyography, which assess the largediameter myelinated fibers and motor units. Furthermore, CSP measurements could be useful in studying the effects of therapeutic analgesic interventions.…”

We evaluated the influence of stimulus intensity (SI) and the amount of voluntary muscle contraction (VMC) on parameters of the cutaneous silent period (CSP). The CSP was measured in 15 healthy subjects at 20%, 40%, and 60% of maximal VMC and after an electric stimulus of 10, 15, and 20 times the sensory threshold. Average EMG amplitudes prior to stimulus and during the CSP increased with the amount of VMC. The CSP duration increased, and suppression index decreased, with increasing SI. The CSP onset and end latencies seemed to shorten and prolong, respectively, with the increasing SI, although this was not statistically significant. Considering the more meaningful temporal parameters of the CSP and the suppression index, it is not necessary to control the VMC, but it is advisable to control the SI.

“…They found that in these patients CSP of reduced duration could be gained when stimuli were applied to two digits. Yaman et al [28] have reported prolonged CSP latency in 35 patients with diabetic neuropathy compared to controls and they found that CSP duration was shortened and prolonged CSP latency in diabetic patients with small fiber neuropathy. These authors concluded that the CSP may be a useful electrophysiological method for the detection and diagnosis of small fiber neuropathy in diabetic patients.…”

Background. Established electrophysiological methods have limited clinical utility in the diagnosis of small fiber neuropathy. The cutaneous silent period (CSP) may be useful as a method for the evaluation of smaller and unmyelinated fiber dysfunctions. Hyperlipidemia is a very rare cause of small fiber neuropathy. In this study, hyperlipidemia and small fiber neuropathy in symptomatic patients with normal nerve conduction studies were evaluated with autonomic tests and cutaneous silent periods. Methods. Twenty-five patients with clinically suspected small fiber neuropathy and 23 healthy volunteers were included. CSP latency and duration, as well as CSP latency difference of the upper and lower extremities, were examined. Two tests were used to assess the autonomic nervous system, namely, the R-R interval variation test in basal and profound breath conditions and the sympathetic skin response. Results. Twenty-five patients with clinically suspected small fiber neuropathy and normal nerve conduction studies were compared with 23 controls. In the upper extremities, patients had prolonged CSP latencies (P = 0.034) and shortened CSP durations (P = 0.039), whereas in the lower extremities, patients had shortened CSP durations (P = 0.001). The expiration-to-inspiration ratios were also reduced in patients groups. There was no significant difference between sympathetic skin response latencies and amplitude of the case and control groups. Conclusion. Our findings indicate that CSP may become a useful technique for the assessment of small fiber neuropathy in hyperlipidemic patients.
