Abstract

Objective: Our goal was to evaluate the efficacy of muscle spasm before and after rehabilitation by comparing shear wave propagation velocity (SWV) and Young's modulus (YM) in the normal and spastic biceps brachii in stroke patients.

Methods: A study of 60 stroke patients with upper limb spasm was performed; these patients were admitted from April 2018 to September 2019. The modified Ashworth scale (MAS) scores of the spastic biceps brachii before and after rehabilitation treatment were compared. SWV and YM on the spastic and normal biceps brachii before rehabilitation treatment, SWV and YM on the spastic and normal biceps brachii after rehabilitation treatment, and SWV and YM on the spastic biceps brachii before and after rehabilitation treatment were compared. Whether SWV and YM on the spastic biceps brachii are related to MAS was compared.

Results: There was a statistically significant difference in SWV and YM between the normal and spastic biceps brachii before (P < 0.01) and after (P < 0.05) the rehabilitation treatment. There was no statistically significant difference in SWV and YM in the normal biceps brachii before and after the rehabilitation treatment (P > 0.05). There was a statistically significant difference in SWV and YM in the spastic biceps brachii before and after the rehabilitation treatment (P < 0.01). SWV and FM of the spastic biceps brachii are correlated with MAS before and after rehabilitation treatment, and the correlation coefficient for SWV was 0.563 and 0.605 for YM (P < 0.05).

Conclusion: SWE can be used as a means of assessment before and after rehabilitation treatment.

SWV was 4.01 m/s (a) on the normal side (left side), and SWV was 6.36 m/s (b) on the spastic side (right side) before rehabilitation treatment. After six weeks of rehabilitation treatment, SWV was 4.34 m/s (c) on the normal side (left side) and 4.95 m/s (d) on the spastic side (right side).
