[Purpose] Brachial-ankle pulse wave velocity (BaPWV), which has been reported as an index of arterial stiffness, is very closely related to cardiovascular risk factors. A high BaPWV indicates high cardiovascular risk. However, BaPWV and pressure waveforms after stroke are not fully understood. [Methods] BaPWV was measured in thirty-two subjects (twenty-two healthy volunteers and ten stroke patients) while they were in the supine position. It was measured in their bilateral upper and lower extremities. [Results] BaPWV was significantly increased in the stroke group compared with the healthy volunteers. It was also significantly increased on both the affected and non-affected sides of stroke patients in the stroke group. Furthermore, analysis of the pressure waveforms showed that the peak pressure was significantly increased in the stroke group compared with the control group. The peak pressure on both the affected and non-affected sides was also significantly greater than in the control group. However, the rise and decay times were significantly decreased in the stroke group compared with the control group. The rise and decay time on both the affected and non-affected sides were also significantly more decreased than in the control group. [Conclusion] The results demonstrated that increased BaPWV and changed pulse waves are closely associated with the pathologic states of hemiplegic stroke patients.
[目的] 肱踝脉搏波速度（BaPWV）作为动脉僵硬度指标，已被报道与心血管危险因素密切相关。高BaPWV表明心血管风险高。然而，中风后的BaPWV和压力波形尚未完全明确。[方法] 对32名受试者（22名健康志愿者和10名中风患者）仰卧位时测量BaPWV，测量双侧上下肢。[结果] 与健康志愿者相比，中风组的BaPWV显著升高。中风组中风患者患侧和未患侧的BaPWV也显著升高。此外，压力波形分析显示，与对照组相比，中风组的峰值压力显著升高。患侧和未患侧的峰值压力也显著高于对照组。然而，与对照组相比，中风组的上升时间和下降时间显著缩短。患侧和未患侧的上升时间和下降时间也比对照组显著缩短更多。[结论] 结果表明，BaPWV升高和脉搏波改变与偏瘫中风患者的病理状态密切相关。
