Objective To compare the effects of Botulinum toxin type A (BTX-A) injection guided with electromyographic/electric stimulation or ultrasonography in patients with post-stroke spasticity of wrist and finger flexor muscles. Methods Inpatients with post-stroke spasticity of wrist and finger flexor muscles accepted BTX-A injection from January, 2015 to May, 2019 were reviewed. They were divided into electromyographic/electric stimulation-guided group (n = 36) and ultrasound-guided group (n = 37). They were assessed with modified Ashworth Scale (MAS) and Fugl-Meyer Assessment (FMA) before injection and four weeks after treatment. Results The scores of both MAS and FMA improved in both groups after treatment (|Z| > 4.654, P < 0.001), and the scores of MAS improved more in the ultrasound-guided group (|Z| > 1.980, P < 0.05), with less dosage of BTX-A (t = 4.023, P < 0.001). Conclusion Ultrasound-guided injection of BTX-A is more effective on wrist and finger flexion muscles spasticity than electromyographic/electric stimulation-guided method in stroke patients.
