To evaluate blood flow of hand arteries (using Doppler ultrasonography) and sympathetic skin response (SSR) in patients with hemiparesis.
Fifty-six stroke patients (30 M, 26 F) with unilateral hemiparesis (age 53.5 ± 10.8 years, mean disease duration 12.0 ± 19.1 months) were included. The patients' arm and hand motor functions were assessed according to Brunnstrom's stages. SSR was evaluated bilaterally from median nerves at the wrist level. Radial and ulnar artery blood flow was measured at the wrist in the neutral position.
Both radial and ulnar artery volume flow and end diastolic velocity, and radial artery diameter were smaller on the paretic side (all p < 0.0125). Radial artery resistance and pulsatility index were greater on the paretic side (both p < 0.0125). SSR amplitude was lower on the paretic side of patients with right-sided hemiparesis patients (p = 0.009). Hand Brunnstrom's stage was negatively correlated with nonparetic-paretic difference in radial artery volume flow and SSR amplitudes (all p < 0.025).
Hand blood flow was lower on the paretic side and was accompanied by a similar decrease in SSR amplitudes in patients with right-sided hemiparesis.
评估偏瘫患者手部动脉血流情况（使用多普勒超声检查）及交感神经皮肤反应（SSR）。
纳入56例单侧偏瘫的中风患者（30例男性，26例女性）（年龄53.5±10.8岁，平均病程12.0±19.1个月）。根据Brunnstrom分期评估患者的上肢和手部运动功能。在腕部水平从中枢神经双侧评估SSR。在中立位测量腕部桡动脉和尺动脉的血流。
患侧桡动脉和尺动脉的容积流量、舒张末期流速以及桡动脉直径均较小（所有p<0.0125）。患侧桡动脉阻力和搏动指数更大（两者p<0.0125）。右侧偏瘫患者患侧的SSR波幅较低（p=0.009）。手部Brunnstrom分期与桡动脉容积流量和SSR波幅的健侧-患侧差值呈负相关（所有p<0.025）。
患侧手部血流较低，且右侧偏瘫患者患侧的SSR波幅也有类似降低。
