Abstract EN
We investigated the effects of different patterns of mechanical tactile stimulation (MS) on corticospinal excitability by measuring the motor-evoked potential (MEP).
This was a single-blind study that included nineteen healthy subjects.
MS was applied for 20 min to the right index finger.
MS intervention was defined as simple, lateral, rubbing, vertical, or random.
Simple intervention stimulated the entire finger pad at the same time.
Lateral intervention stimulated with moving between left and right on the finger pad.
Rubbing intervention stimulated with moving the stimulus probe, fixed by protrusion pins.
Vertical intervention stimulated with moving in the forward and backward directions on the finger pad.
Random intervention stimulated to finger pad with either row protrudes.
MEPs were measured in the first dorsal interosseous muscle to transcranial magnetic stimulation of the left motor cortex before, immediately after, and 5–20 min after intervention.
Following simple intervention, MEP amplitudes were significantly smaller than preintervention, indicating depression of corticospinal excitability.
Following lateral, rubbing, and vertical intervention, MEP amplitudes were significantly larger than preintervention, indicating facilitation of corticospinal excitability.
The modulation of corticospinal excitability depends on MS patterns.
These results contribute to knowledge regarding the use of MS as a neurorehabilitation tool to neurological disorder.
