目的：探讨超声弹性图显示中风后痉挛肌肉僵硬的可行性，以及前臂痉挛肌肉的超声弹性图表现与临床痉挛评分的关系。23例有前臂肌肉痉挛的卒中患者(改良Ashworth评分为1+，Tardieu评分为1)。对患侧和健侧的指浅屈肌、指深屈肌、腕尺屈肌和桡侧腕屈肌的弹性指数和弹性比进行测量。结果：偏瘫侧腕、指屈肌的弹性指数和弹性比明显高于健侧(p<；0.05)。指深屈肌的弹性指数和弹性比与屈指角度呈负相关(r=-0.418和r=-0.469)。指浅屈肌痉挛状态下测得的弹性指数与指屈肌的迟滞角呈负相关(r=-0.435)。结论：超声弹性图可为痉挛状态的诊断和随访提供客观的评价。为了加强这一预测，还需要进一步的研究。知识进展：这项研究的结果表明，超声弹性图是前臂肌肉痉挛的一种有前途的评估方法。
Objective: The aim of the study was to investigate the feasibility of sonoelastography to show muscle stiffness in post-stroke spasticity, and the relationship between sonoelastography findings and clinical spasticity scores in the spastic forearm muscles.Methods: This study was carried out in a university rehabilitation centre. 23 patients with stroke with forearm muscle spasticity (>= 1+ using the Modified Ashworth scale score and >= 1 using the Tardieu scale) were included. Sonoelastography parameters (elasticity index and elasticity ratio) were measured from the flexor digitorum superficialis, flexor digitorum profundus, flexor carpi radialis and flexor carpi ulnaris muscles on the affected and unaffected sides.Results: Both elasticity index and elasticity ratio of the wrist and finger flexors on the hemiplegic side were significantly increased compared with those on the healthy side (p < 0.05). The Tardieu angle of finger flexors was negatively correlated with the elasticity index and elasticity ratio measured in the spastic flexor digitorum profundus (r = -0.418 and r = -0.469, respectively). Tardieu angle of finger flexors was negatively correlated with the elasticity index measured in the spastic flexor digitorum superficialis (r = -0.435). There was no correlation between other parameters.Conclusion: Sonoelastography may provide objective assessment of spasticity both in diagnosis and follow-up. To strengthen this prediction, further studies are necessary.Advances in knowledge: The results of this study represent that sonoelastography is a promising evaluation method for forearm muscle spasticity.
