Micturition Desire-Relaxation Training Device for Lower Urinary Tract Dysfunction in Children

The device was developed by Shanghai Children's Medical Center in collaboration with Shanghai University of Engineering Science. It plays relaxation videos through a VR device and monitors the subjects' brain waves in real time using electroencephalography to evaluate their relaxation levels. The relaxation material is adjusted accordingly, and urination is recorded after training. Urine is collected and analyzed with a flow meter, generating a diagnostic report.

Participants diagnosed with nocturnal enuresis, daytime urinary incontinence, and urinary frequency will be screened at Shanghai Children's Medical Center, and eligible patients will be recruited. Participants will be randomly assigned to the sham training group, in which they will wear the device without powering it on for 10 minutes each session, 5-10 times a day, for 4 weeks.
