A Preliminary Study on Sympathetic Skin Response in Acute Ischemic Cerebrovascular Disease

Figures & data

Table 1 SSR Test Results of Upper Limbs in Control Group

Side	n	Latency (s)	Amplitude (mV)
Left	30	1.37±0.07	1.14±0.94
Right	30	1.37±0.07^Δ	1.11±0.80^Δ

Notes: ^ΔIndicates that the value was obtained by comparing with the left side, p>0.05.

Table 2 Comparison of SSR Test Results of Upper Limbs in AICVD Group

Group Side	n	Latency (s)	Amplitude (mV)
TIA
Healthy	20	1.52±0.15*	0.71±0.60*
Affected	20	1.53±0.13*	0.63±0.65*
AIS
Healthy	46	1.67±0.36*	0.62±1.13*
Affected	46	1.61±0.26*	0.60±0.93*

Notes: *Indicates that the value was obtained by comparing with the control group, P<0.05. The AIS group in the above table included two cases with bilateral lesions; the cases with disappeared waveform were excluded from the calculations of latency and amplitude.

Table 3 Analysis of Correlation Between SSR Results and NIHSS, BI and ESRS Scores

Rating Scale	n	SSR Results		Spearman Analysis
		X^2	P	r	P
NIHSS	66	10.348	0.006*	0.347	0.004*
