Cortical Activity During Vojta Stimulation in Healthy Adults

Brain

Electroencephalography, Electromyography, Tactile stimulation, Vojta therapy

The present study is focused on the importance of sensory stimuli at the tactile and proprioceptive level that occur during the activation of the pectoral area, following the treatment protocol of Vojta Therapy (VT), and which are the areas that are activated in the central nervous system (CNS) during stimulation, as well as muscle activity. For the activation record it will be used electroencephalography and electromyography electrods.

The relationship between intrinsic and extrinsic factors condition the development of the human being. The sensory organs are the main recipients of the information, thanks to them we are able to interact with the environment and register the influence of the stimuli inside the organism. The brain receives information from the environment through its senses. At the tactile level the brain receives afferent information thanks to the activation of mechanoreceptors of the skin during interaction with the environment. The receivers encode the stimulus information and send it to the specific CNS structures. In these structures, the sensations received are combined and the stimulus is transformed into a perfectly elaborated response, both in a conscious and innate way. Dr. Vojta showed in 1974 the locomotion reflects the result of the study of motor ontogenesis. This discovery was the demonstration of the existence of innate and preprogrammed motor patterns in Humans. Most of the studies related to VT have showed the improvements obtained by the patients, validating it as a method of treatment and evidencing objective changes after its application. This research aim to go further and verify that cortical areas are activated during the application of an external and proprioceptive stimuli that are performed during the first phase of VT turning and which areas are responsible for producing and organizing the efferent response.
