Effect on gait and motor symptoms
INTERACTION
Two‐way ANOVA showed a significant interaction between group and condition effect in gait parameters including step length (Effects of taVNS on gait parameters and motor symptoms. (A) Interaction effect on gait parameters including step length, variability of step length, stride velocity, and stride length. (B) Main effect of group (taVNS stimulation vs. sham stimulation) on gait parameters including gait cycle and double support. (C) Effect on motor symptoms including TUG, UPDRS‐3, Tinetti Balance, and Tinetti Gait scores. A Bonferroni‐corrected threshold was set at No difference was found in the group main effect, condition main effect, or interaction when analyzing the motor symptoms including UPDRS‐III, TUG, Tinetti Balance, and Gait scores (
