An interventional study of Neurofeedback and Sham-feedback in Somatosensory Evoked Potentials, and Electroencephalography, sponsored by Keio University. Completed at 1 site in Japan. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-02-07.
Sponsored by Keio University · Not applicable, Interventional, and Basic science
The purpose of this study is to examine the functional and structural modification effects on the brain of a non-invasive experimental device applied to the head and forearms of healthy subjects during motor recall training. The experimental device used in this study is the Brain-Machine Interface (hereinafter referred to as BMI), which is under development in the principal investigator's laboratory. The BMI consists of an arithmetic unit that processes the results in real time using a personal computer, a depth ray that displays the results, a transcutaneous electrical stimulator that is driven based on the results of the arithmetic, and an exoskeletal motor assist device that is driven based on the results of the arithmetic.
This study does not fall under the category of 'medical research involving human subjects' or 'clinical research subject to legal regulations' in Japan, and the appointment of a principal investigator (PI) is not required. For the convenience of registry submission, the name of the principal investigator field has been filled with the name of the study representative (a non-physician).
Keio University is the lead sponsor of 11 studies on the registry; 2 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
Participants in the group received real-time feedback of their own electroencephalogram signal
Behavioral: Neurofeedback
Participants in the group received feedback of electroencephalogram signal previously recorded from other participants.
Behavioral: Sham-feedback
The participants received visual feedback of the processed result of neural signals acquired online.
Previously recorded neural signals are processed and presented to participants as if the signals from them are processed online.
Somatosensory evoked potential
Median nerve stimulation elicits the somatosensory evoked potentials. Their amplitude was calculated.
Time frame: From the timing of pre-training evaluation (before the intervention) to the end of evaluation (after the intervention), with the intervention lasting 30 minutes.
Touch typing performance
A touch typing task was employed to test sensorimotor integration performance
Time frame: From the timing of pre-training evaluation (before the intervention) to the end of evaluation (after the intervention), with the intervention lasting 30 minutes.
