UMIN ID: UMIN000036623

Registered date:29/04/2019

Basic Information

• Recruitment status: Complete: follow-up complete
• Health condition(s) or Problem(s) studied: Healthy and neurologically intact adults
• Date of first enrollment: 2019/04/29
• Target sample size: 20
• Countries of recruitment: Japan
• Study type: Interventional

Intervention(s)

A square electrode 2 cm on a side was applied at both sides mastoid process of participant. A battery-powered current stimulator delivers 100-640 Hz sinusoidal stimuli for 10 minutes (peak-to-peak amplitude = 0.4 mA). Participants were asked to fixate the dot with their eyes and rotate their head before, during, and after stimulation (1 Hz and 30 rotations).

Participants were asked to fixate the dot with their eyes and rotate their head before, during, and after 10-minutes sham stimulation including 1-minute actual stimulation (1 Hz and 30 rotations).

Outcome(s)

• Primary Outcome: Coherence between eye and head rotation movements is recorded before, during, and after transcranial alternating current stimulation.
