Clinical effect of ultrasound guidance combined with electrical stimulation botulinum toxin type A injection in upper limb spasticity due to stroke

Objective To evaluate the clinical effect of ultrasound guidance combined with electrical stimulation botulinum toxin type A(BTX-A) injection in upper limb spasticity(ULS) in poststroke patients.Methods Twenty-three patients with ULS following stroke were recruited.Under the guide of color Doppler ultrasound combined with electrical stimulation,BTX-A was injected into multi-points of muscles.Conventional rehabilitation training was performed after BTX-A injection.The outcome after BTX-A injection was assessed by modified Ashworth scale(MAS),active rang of movement(AROM) and Fug1-Meyer assessment(FMA).All assessments were performed at the baseline,1,2,4 and 12 weeks after injection,respectively.Results Compared with pre-injection,scores of MAS,AROM and FMA were obviously improved 1,2,4 and 12 weeks after BTX-A injection(all P0.05).Conclusion Ultrasound guidance combined with electrical stimulation injection is an accurate positioning method in using BTX-A to treat ULS in strokes.
