Brief summary
The vibration stimulation is regarded as a new method of training and therapy to change afferent parts and cortical projections, which are important for motor control. This study aims to check effects of different frequency parameters for electrical cortical potentials and electrical muscular potentials in healthy young adults. 80 volunteers will participate in the study, and they will be randomly subdivided in four groups for trials. The methodology consists of electroencephalographic and electromyographic assessment before and after 15-minute vibration application with a digital vibratory pad.
Detailed description
The vibratory stimulation is regarded as a new training method and capable of modulating peripheral afferents and cortical projections therapy, which are important in motor control. This study aims to determine the effects of different parameters on cortical frequency electric potential and electric potential muscle in healthy young adults. Will participate in the study 80 volunteers, these randomly divided into four groups for the experimental procedures. The methodological approach consists of an electroencephalographic and electromyographic evaluation before and after 15 minutes of application of vibration through a digital vibrating pad.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Effect of vibration stimulation applied to different frequencies in cortical excitability and muscular function: randomised clinical trial | 1 month | We know that the vibration has multiple physiologic effects, promoting normal patterns of motor activity by changing motor-neuron excitability. Vibrations increase the final afferent influx of the primary muscular fuse, allowing the reflex contraction, the so-called tonic vibration reflex . This reflex is mediated by both segmental and supra-segmental spine path, and is supported by upper centres. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Effect of vibration stimulation applied to different frequencies in cortical excitability and muscular function: randomised clinical trial | 1 month | The 80 volunteers will be randomly gathered in study groups by random computer-given numbers. From these 80 volunteers, 20 will be in the evaluation group (EG); 20 will participate in the group of low-frequency vibration stimulation (LFVS); 20 in the group of medium-frequency vibration stimulation (MFVS); and 20 will take part in the group of high-frequency vibration stimulation (HFVS). The three groups is intended to observe increased electromyographic activity of the muscles |
