AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with paralysis or loss of both arms. It tests a small wireless brain implant that lets people control devices such as a cursor.
- Age
- 18 to 80 years
- Sex
- All genders can join.
- Disease stage
- Spinal cord injury, brainstem stroke, amyotrophic lateral sclerosis or another motor neuron disease causing partial or complete paralysis, or loss of both arms. The diagnosis must be stable for at least 6 months and the condition present for at least 1 year.
- Earlier treatment
- No earlier implanted metal objects or devices, except dental implants or implants that have no impact. People on long-term blood thinners must have stopped them enough.
Main reasons for not taking part
- Cannot tolerate anesthesia or surgery
- Abnormal blood clotting test results
- Severe brain or nerve disorder, or cognitive or psychiatric disorder
- Acute or severe infection, or a scalp condition that may slow wound healing
- Pregnant, breastfeeding or planning pregnancy during the study

A Prospective Clinical Trial to Evaluate the Safety and Efficacy of Implantable Wireless Recording System (WRS) for General Control of External Devices in Paralyzed/Amputee Patients
The clinical trial aims to evaluate the safety and efficacy of the minimally invasive, wireless brain-machine interface system (WRS) in enabling general brain control of external devices, such as a cursor and other assistive technologies, for paralyzed and amputee patients.
WRS integrates a high-throughput, ultra-flexible neural electrode with an extremely small cross-sectional size-approximately one-hundredth the diameter of a human hair. Moreover, the implantable component is fully embedded within the body, leaving no visible external traces.
Inclusion: Aged 18-80 years (inclusive), any gender; Diagnosed with spinal cord injury, brainstem stroke, amyotrophic lateral sclerosis, or other motor neuron diseases causing partial or complete paralysis, or bilateral upper limb amputation; Diagnosis stable for at least 6 months before screening, with the condition present for at least 1 year; Willing to follow the study protocol and attend all visits, with or without caregiver assistance; Informed consent signed by participant and/or caregiver, with full understanding of the trial's purpose.
Exclusion: Previous implantation of metal objects or devices (except dental implants or non-impacting implants); Unable to tolerate anesthesia or surgery; Drug or alcohol abuse; Severe neurological disorders or brain injury leading to significant dysfunction; Scalp conditions that may impair wound healing; Acute or severe infections; Cognitive impairment or psychiatric disorders; Severe dysfunction of vital organs, malignancies, or autoimmune diseases; Other conditions deemed unsuitable by the investigator; Long-term use of anticoagulants/antiplatelets with insufficient cessation, or abnormal coagulation test results; Life expectancy under 1 year; Pregnant, breastfeeding, or planning pregnancy during the study.
