The physiotherapeutic technique of Vojta reflex locomotion is often accompanied by various autonomic activity changes and unpleasant sensations. It is unknown whether these effects are specific to Vojta Therapy. Therefore, the aim of this study was to compare changes in cardiac autonomic control after Vojta reflex locomotion stimulation and after an appropriate sham stimulation.
A total of 28 young healthy adults (20.4 - 25.7 years) were enrolled in this single-blind randomized cross-over study. Participants underwent two modes of 20-minute sustained manual pressure stimulation on the surface of the foot on two separate visits. One mode used manual pressure on the lateral heel, i.e., in a zone employed in the Vojta Therapy (active stimulation). The other mode used pressure on the lateral ankle (control), in an area not included among the active zones used by Vojta Therapy and whose activation does not evoke manifestations of reflex locomotion. Autonomic nervous system activity was evaluated using spectral analysis of heart rate variability before and after the intervention.
The active stimulation was perceived as more unpleasant than the control stimulation. Heart rate variability parameters demonstrated almost identical autonomic responses after both stimulation types, showing either modest increase in parasympathetic activity, or increased heart rate variability with similar contribution of parasympathetic and sympathetic activity.
The results demonstrate changes of cardiac autonomic control in both active and control stimulation, without evidence for a significant difference between the two.
vojta反射运动的物理治疗技术常伴随着各种自主神经活动变化和不适感。尚不清楚这些效应是否是vojta疗法所特有的。因此，本研究的目的是比较vojta反射运动刺激后和适当的假刺激后心脏自主神经控制的变化。
本单盲随机交叉研究共纳入28名年轻健康成年人（20.4 - 25.7岁）。参与者在两次单独就诊时接受了两种20分钟持续手动足部表面压力刺激模式。一种模式是在足跟外侧施加手动压力，即vojta疗法中使用的区域（主动刺激）。另一种模式是在踝关节外侧施加压力（对照），该区域不在vojta疗法使用的活跃区域内，其激活不会引起反射运动表现。干预前后通过心率变异性频谱分析评估自主神经系统活动。
主动刺激比对照刺激更令人不适。两种刺激类型后心率变异性参数显示出几乎相同的自主神经反应，要么副交感神经活动适度增加，要么心率变异性增加，副交感神经和交感神经活动贡献相似。
结果表明主动刺激和对照刺激均有心脏自主神经控制变化，但两者之间无显著差异。
