Brain-computer-interface rehabilitation and neural interfaces

What it is

A brain-computer interface (BCI) records brain activity linked to the intention to move. It decodes that activity and uses it to drive something outside the body: a hand exoskeleton, muscle stimulation, a computer cursor or a communication interface. The two uses work differently.

Format

• Phase A: Considering a BCI (before referral or enrolment). Goal: an informed, unpressured decision with realistic expectations. Format: 1 to 4 sessions, individual or with family, alongside the team's own consent process. Move on when the client can describe in their own words what the device does…
• Phase B: Starting and early use. Goal: support engagement, frustration tolerance and early meaning-making. Format: sessions spaced to match the rehabilitation schedule. Move on when the client has a workable routine and a way to report problems to the team.

Who practises it, and how they are trained or regulated

• Version followed: two separate things are described here. (1) Non-invasive BCI rehabilitation for chronic stroke, as the FDA's April 2021 De Novo authorisation of the Neurolutions IpsiHand Upper Extremity Rehabilitation System describes it, and as the brain-actuated functional electrical stimulation (BCI-FES) trial by Biasiucci, Millán and colleagues (Nature Communications, 2018) describes it. (2) Implanted…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• Does it use a device, heat, cold, water or a physical procedure? Has a medical professional checked that it is safe for you?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• Unclear roles, or the client bringing device questions to you because the team feels hard to reach.
• A caregiver pushing harder than the client. Burnout. Role reversal and resentment. Signs it is working: a shared, realistic plan.
• Comparison and envy, distress about public comments, privacy breaches. Signs it is working: the client makes deliberate choices about exposure.
• Fatigue, discomfort or skin redness. Problems with fit because of spasticity. Discouragement if gains are slow. Pass physical complaints to the treating team.
• Hidden non-use. Shame about "failing" the device. Fatigue that may need medical review. Signs it is working: honest reporting to the team and a sustainable routine.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
