Spasticity is one of the most important causes of disability after stroke. In spite of high incidence of spasticity, little is known about the relationship between the occurrence and the development of spasticity. This study aimed to determine risk-factors of post stroke spasticity.
This was an observational study of 149 persons with first ever stroke. The following parameters were assessed: Stroke severity, Spasticity, Disability and Joint contracture.
Prevalence of spasticity was between 17-25% during the first 3 months after stroke. The onset of spasticity was 13.79% and 4.16% at 1 and 3 months after stroke respectively. The prevalence of spasticity in the upper extremity was significantly more than lower extremity at 1 month. Spasticity was significantly more severe in the upper extremity than lower extremity. In patients with hemorrhagic stroke Odds ratios of spasticity was 2.5 times more than persons with ischemic stroke (P = 0.0210. The Odds ratios of severe spasticity at 1 and 3 months were 1.66 and 1.75 times more than the first week (P = 0.024, P = 0.042 respectively).
Post stroke spasticity is more common in persons with hemorrhagic stroke, severe paresis and lower functional abilities. The most incidence of spasticity happens in the first month after stroke.
痉挛是中风后导致残疾的最重要原因之一。尽管痉挛的发病率很高，但对于痉挛的发生和发展之间的关系知之甚少。本研究旨在确定中风后痉挛的危险因素。
这是一项对 149 名首次中风患者的观察性研究。评估了以下参数：中风严重程度、痉挛、残疾和关节挛缩。
中风后 3 个月内痉挛的患病率在 17-25%之间。痉挛的发病时间分别为中风后 1 个月和 3 个月时的 13.79%和 4.16%。在 1 个月时，上肢痉挛的患病率明显高于下肢。上肢痉挛的严重程度明显高于下肢。与缺血性中风患者相比，出血性中风患者的痉挛发生率高出 2.5 倍（P=0.0210）。1 个月和 3 个月时严重痉挛的比值比分别为首次发病后 1.66 倍和 1.75 倍（P=0.024，P=0.042）。
与缺血性中风患者相比，出血性中风、严重瘫痪和较低功能能力的患者更容易出现中风后痉挛。痉挛的发病率最高发生在中风后第一个月。
