[Purpose] This study aimed to investigate the effects of Vojta therapy on 
spatiotemporal gait parameters in children with spastic diplegia. [Methods] The 
study population consisted of 3 children diagnosed with spastic diplegia. The 
subjects were treated with Vojta therapy for 8 weeks and followed up for 8 weeks 
after completion of the therapy. Vicon motion analysis was used to determine the 
subjects' spatiotemporal gait parameters. [Results] The following results were 
noted in the changes of each joint angle in the sagittal plane after Vojta 
therapy. Subject 1 remained in phase throughout the entire gait cycle and did 
not show any noticeable improvement, even demonstrating a negative range of 
motion when compared to the baseline. Subject 2 showed a normal anti-phase in 
heel strike, and the mid-stance, and swing phases. Subject 3 showed a normal 
anti-phase in heel strike and mid-stance, but the anti-phase during the swing 
phase was not significantly different from the baseline. For subjects 2 and 3, 
compared to the baseline, the range of motion of the hip and knee increased but 
the range of motion of the ankle decreased. [Conclusion] The findings of this 
study indicate that Vojta therapy can do a good role in improve the 
spatiotemporal gait parameters of children with spastic diplegia.
