Functional electrical stimulation

Domain IX · Biomedical, neuro & digital

What it is

Functional electrical stimulation (FES) delivers small electrical pulses to a nerve, usually through adhesive skin-surface electrodes (less often through implanted electrodes), so that a weak or paralysed muscle contracts at the moment it is needed for a functional movement. NICE describes the aim…

Format

• FES has no psychotherapeutic phases. The pathway below is the treatment pathway as clinics and commissioners describe it, with the psychotherapist's parallel tasks. Session counts for FES are set by the treating team and are not given here.
• Referral by a doctor or therapist to a specialist FES or gait service. In England, NHS funding for foot-drop FES is decided locally and often requires prior approval or an individual funding request.

Who practises it, and how they are trained or regulated

• Regulatory and guideline status (as of October 2026)
• Stroke, National Clinical Guideline for Stroke (2023, UK and Ireland): FES to the wrist and finger extensors should be considered as an adjunct to conventional therapy where weakness limits function; electrical stimulation for subluxation within six months; electrical stimulation should not be used to reduce spasticity; AFO and/or FES may be considered for limited dorsiflexion affecting balance, with training for…
• United States: foot-drop stimulators are regulated as Class II devices under 21 CFR 882.5810 (external functional neuromuscular stimulator) via 510(k) clearance. For example, the Bioness L300 Go System (K173682, cleared 9 March 2018) is indicated to provide ankle dorsiflexion in adult and paediatric individuals with foot drop and to assist knee flexion or extension in adults with weakness from upper motor neuron…

Evidence status, as the guide reports it

• England and Wales, NICE IPG278 (2009, updated 2012): evidence on safety and efficacy in terms of improving gait is adequate to support use, provided normal arrangements are in place for clinical governance, consent and audit. Patient selection for implantable FES should involve a multidisciplinary…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• How do you and the practitioner understand what is happening, in spiritual or cultural terms? Is that a source of comfort, worry, or both?
• 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

• clients downplaying problems for fear of losing the device. Working: the team hears about problems promptly.
• the client pinning all recovery hopes on the device. Working: the client holds hope and a plan B at the same time.
• hopelessness after a funding refusal, a fall, or device withdrawal. Working: the client can name and use the plan.
• resentment, over-protection, or safeguarding concerns. Working: both describe the arrangement as fair and workable.
• avoidance that limits participation more than the disability does. Working: the client re-enters valued social settings.

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.
