Raw data of BR and LSR. (A) Changes in BR. Compared to nonspasm side at baseline, the amplitude of R1 was higher, the duration of R2 was longer, and the area of R2 was larger in the spasm side. After 30 weeks of EA treatment, the duration of R2 was shortened and the area of R2 was reduced in the spasm side, and there were no changes in the nonspasm side. (B) Occurrence of LSR in O.oc and O.or (the blue arrow). After EA, no LSR was found in the facial muscles. BR, blink reflex; LSR, lateral spread responses; O.oc, Orbicularis oculi muscle; O.or, Orbicularis oris muscle.

EMG activities in the Orbicularis oris (O.or) or the Orbicularis oculi (O.oc) muscle by stimulating the mandibular or zygomatic branches of the facial nerve, respectively. EMG test showed that the spastic side had higher R1 amplitude, longer R2 duration, and larger R2 area than the non-spasmodic side (Figure 1A, Supplementary Table S1). Table 1). The duration of R2 was shortened by 5.35ms, the area of R2 was reduced by 13.56%, and the LSR of O.oc and O.or disappeared on the spasm side (Figure 1B).
