- W2341780703 abstract "OBJECTIVE: The aim of this study was to assess neuronal plasticity occurring in healthy volunteers after sustained pressure stimulation according to Vojta. BACKGROUND: The Vojta therapy is a physiotherapeutic method involving sustained manual stimulation at specific skin zones to elicit a complex motor response, so called reflex locomotion. Despite 50 years of clinical use, the underlying neurobiological basis remains a speculation. We hypothesize that the stimulation-driven response induces brain plasticity mainly at subcortical level. To detect site-specific changes, we compared two peripheral stimulation sites using task-related and resting-state functional magnetic resonance imaging (fMRI). DESIGN/METHODS: Two groups of healthy volunteers were included (17 females and 5 males in each group, mean ages 24.5 and 24.7, respectively): Group A receiving stimulation at the Vojta right heel zone and Group B receiving control stimulation at the right ankle. All subjects underwent a single fMRI session using a 1.5T Siemens scanner, employing twice 3 different conditions: rest (6 min); dominant hand finger tapping alternating with rest (6 min); intermittent pressure stimulation applied by an experienced therapist (10 min). Both rest and finger tapping conditions were tested before and after two consecutive stimulation runs. Statistical analysis was carried out using FSL version 5.0. The resulting maps were thresholded at corrected significance level p<0.05. RESULTS: In finger tapping task, diffuse activation decrease within sensorimotor system was observed in both groups. However, there was significant activation increase mainly in motor nuclei of left thalamus detected only in group A. Additionally, group A showed significant decrease of functional connectivity in the left superior parietal lobule within the bilateral sensorimotor resting-state network. CONCLUSIONS: Our findings provide evidence that the stimulation according to Vojta is associated with specific and persistent changes of brain activation mainly at subcortical level, as compared to the control stimulation.
