实时剪切波弹性成像技术评估脑卒中后下肢肌张力的研究
Study of real-time shear wave elastography in evaluating the lower limb muscle tension after stroke
摘要
Abstract
Objective To explore the feasibility of real-time shear wave elastography (SWE) in evaluating the muscle tension of patients with lower limb spasticity after stroke. Methods A total of 30 patients with lower limb spastic hemiplegia after stroke (case group) and 30 healthy volunteers (control group) were selected. The Young's moduli of the patients' gastrocnemius muscle in both sides and volunteers' right gastrocnemius muscle were measured by SWE. Results In prone position, the average Young's moduli of the gastrocnemius muscle in the pathological side of the case group, contralateral side of the case group, and right gastrocnemius of the control group were (62.28 ± 19.22) kPa, (22.47 ± 7.42) kPa and (20.47 ± 2.47) kPa, respectively. In supine position, the average Young's moduli of the gastrocnemius muscle in the pathological side of the case group, contralateral side of the case group, and right gastrocnemius of the control group were (62.44 ± 18.49) kPa, (21.10 ± 2.28) kPa and (20.17 ± 2.13) kPa, respectively. The mean young's moduli of the gastrocnemius muscle in the pathological side of the case group were higher than those in the contralateral side of the case group and right gastrocnemius of the control group ( P< 0.05). Conclusions SWE can quantitatively assess the stiffness variation of the spasticity muscle and evaluate the change of muscle tension, which can direct clinical treatment.关键词
