A study to investigate the effects of electrical stimulation on the vestibular organs that maintain the body's balance on the balance response, focusing on changes in brain activity and muscle activity.

Conditions

The subjects of this study will be healthy adults without pre-existing vestibular organ damage or neurological disorders, and the effects of galvanic vestibular stimulation on the human recovery response will be investigated. Based on the effects generated in healthy adults, we expect to be able to apply this method to rehabilitation of stroke patients in the future.

Interventions

The group will be divided into two groups depending on which of two conditions is initiated: the condition in which galvanic vestibular stimulation is given during righting reaction (intervention cond

Exclusion criteria

Exclusion criteria: Exclude those with pre-existing vestibular or neurological disorders and those who cannot hold an sitting position for 30 minutes.

Design outcomes

Primary

Measure	Time frame
The participants will perform the righting reaction task under the condition of galvanic vestibular stimulation (intervention condition) and under the condition of no galvanic vestibular stimulation (sham condition). The following items were measured for 1 minute during the standing righting reaction exercise in the intervention and sham conditions Surface EMG: upper trapezius, paraspinal erector spinae, external oblique abdominal muscles, and rectus femoris Cerebral blood flow: fNIRS	—
