Cortical Effects of Peripheral Proprioceptive Stimulation on the Motor Evoked Potentials of the Limbs

NCT06936579 · Status: NOT_YET_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 31

No results posted yet for this study

Summary

Through motor muscle potentials, we will observe how a peripheral somatosensory mechanical stimulus on key limb musculature communicates signals via afferent sensory fibers that encode proprioceptive signals from muscle spindles (particularly type Ia fibers) to the somatosensory cortex at rest, confirming the integrative hypothesis of movement.

These results would support interventions aimed at addressing sensory deafferentation present in multiple health conditions related to movement disorders, where disuse or immobilization lead to changes in movement patterns and a decrease in neuronal activation in somatosensory cortex areas involved in constructing voluntary movement.

Interventions

DEVICE

proprioceptive stimulation

Condition without proprioceptive stimulation: Participants will not receive the stimulus, and MEP activity will be recorded under the same motor cortex stimulation conditions. Condition with proprioceptive stimulation 1: Participants will receive proprioceptive stimulation through the output plunger, applied continuously for 15 seconds, with 20-second rest intervals, over a total duration of 5 minutes. MEP activity will then be recorded via motor cortex stimulation. Condition with proprioceptive stimulation 2: Participants will receive proprioceptive stimulation continuously during the application of TMS pulses while MEP activity is recorded.
