Trials

The study involves no implant and tests no device. It asks 50 adults with acquired blindness what existing assistive devices get wrong, and what they would want from a vision-restoration implant. Outcomes span demographics and economics, quality of life, clinical features, satisfaction with current aids, and design requirements for an invasive visual brain-computer interface. Participants must be at least 18, have only weak or no light perception in both eyes, and have lost their sight after birth; congenital blindness is excluded.

The trial compares motor imagery BCI plus standard rehabilitation against standard rehabilitation alone in stroke patients with hemiplegia, tracking limb motor function and daily living ability. It planned to enroll 60 participants, 30 per arm, with the first participant enrolled on August 10, 2022; the registry now lists the study as completed. Beyond motor scales, the primary outcomes include functional connectivity and a lateralization index measured with fNIRS, probing brain-network changes rather than behavior scores alone.

OYMotion and MicroPort NeuroScientific signed a strategic cooperation agreement on May 28, 2026 to jointly develop an interventional brain-computer interface rehabilitation system. The first product will be a multi-channel endovascular BCI that threads a signal-recording stent through the blood vessels to a target brain region, capturing intracranial electrical activity without opening the skull. MicroPort NeuroScientific will build the BCI system as a whole and OYMotion the limb side, with the pair targeting medical rehabilitation and human-machine interaction.

A newly registered trial tests a brain-computer interface in post-stroke rehabilitation across 4 parallel arms: full cross-domain (emotion-cognition-motor) adaptive training, integrated cognitive and motor task training, single-dimension motor training, and conventional rehabilitation. Each arm plans 22 participants, 88 in total. It enrolls patients aged 30 to 80 with a first cerebral infarction or hemorrhage 3 months to 1 year earlier, unilateral hemiplegia, and upper-limb Brunnstrom stage II to IV. The primary outcome is a motor function score; secondary outcomes include EEG motor imagery event-related synchronization/desynchronization, prefrontal theta/alpha power ratio, and EEG-fNIRS coupling.

Women with overactive bladder often rely on drugs and behavioral training, with limited relief. A newly registered trial at The First Affiliated Hospital of Soochow University takes a different route: patients perform a task while functional near-infrared spectroscopy reads prefrontal brain activity, and an algorithm decides when to deliver transcranial magnetic stimulation, closing the loop. The interventional, parallel-design trial plans to enroll 66 women aged 18 to 75, 33 in the experimental arm and 33 in a control arm that receives open-loop sham stimulation, with the overactive bladder symptom score as the primary endpoint. No device model or results are disclosed in the registration, and recruitment has not yet started.

Punan Hospital, Pudong New Area, Shanghai is the sponsor, with first enrolment set for May 30, 2026. The trial is registered with the Chinese Clinical Trial Registry (ChiCTR) under number ChiCTR2600125531, with a registration date of May 28, 2026, and recruitment has not yet started.

A trial at Xuzhou Rehabilitation Hospital Affiliated to Xuzhou Medical University paired a motor imagery brain-computer interface with modified constraint-induced movement therapy to restore upper-limb function after stroke. The hospital is a rehabilitation specialty facility affiliated with Xuzhou Medical University, and the combined approach is meant to test whether a BCI adds benefit on top of established rehabilitation training. It planned 40 participants, 20 in the combined group and 20 in the control group, with the first patient enrolled on December 24, 2025; the registry now lists the study as completed.

Funding comes from the New Round of Xuzhou "Pengcheng Talent Program" — High-level Healthcare Talent Recruitment and Development Project, project number 2025TD14. No results are posted, so whether the combined approach beats constraint therapy alone remains unknown.
