Abstract:
Objective:To explore the clinical application value of sound touch elastography (STE) in the evaluation of the curative effect of acupuncture and moxibustion in the treatment of stroke patients with upper limb spasm.Methods:Fifty-five patients with upper limb spasm after stroke were selected as stroke group, and thirty healthy volunteers matched with age, gender and body mass index (BMI) were selected as control group between September 2020 and March 2021. The shear wave velocity (SWV) of biceps brachii and triceps brachii were measured in both groups. In stroke group, the SWVs of biceps brachii and triceps brachii on spastic side and non-spastic side were measured before and after acupuncture treatment, and the correlations between SWV and spastic grade (X), muscle response angle (R1), passive range of motion (R2), spastic angle (R2-R1) of modified Tardieu scale (MTS) were analyzed.Results:At 0 degree, the SWV of spastic biceps brachii (3.85±0.62)m/s was significantly higher than those of the non-spastic side [(3.34±0.35)m/s] and control group [(3.15±2.66)m/s] (all P<0.001), and decreased [ (3.45±0.47)m/s] after acupuncture treatment ( P<0.001). At 90 degree, the SWV of non-spastic biceps brachii was larger than those of spastic side and control group [1.98(1.92, 2.14)m/s vs 1.98(1.92, 2.11) m/s, 1.95(1.86, 2.05)m/s, all P<0.05], and there was no significant difference between the SWV of spastic side and control group ( P>0.05). There were no significant differences in SWV of triceps brachii between the spastic side and control group at both 0 degree or 90 degree ( P>0.05). At 0 degree, SWV positively correlated with MTS (x) ( rs=0.639, P<0.001) and negatively with R1 ( rs=-0.527, P<0.001) and R2 ( rs=-0.825, P<0.001) on the spastic biceps brachii. Conclusions:STE can provide quantitative index for the objective evaluation of the curative effect of acupuncture in upper limb spasm after stroke, and it is proposed to be an effective means of clinical diagnosis and efficacy evaluation in patients with upper limb spasm after stroke.
