Physiotherapy for Functional Neurological Disorder in Bolton

Functional neurological disorder produces genuine neurological symptoms — limb weakness, tremor, gait problems, dystonia, sensory disturbance, functional seizures — arising from a problem with how the nervous system is functioning rather than from structural damage to it. The common analogy is a software problem rather than a hardware one: the wiring is intact, the signals are not getting through as they should.

Two things follow from that, and both matter:

• The symptoms are not imagined, exaggerated or under your control. People with FND are frequently disbelieved, including by clinicians, and arrive having been told there is "nothing wrong". There is something wrong. It is simply not the kind of thing an MRI shows.
• Because the hardware is intact, improvement is genuinely possible in a way it is not after a stroke has destroyed tissue. That is the basis for treating it.

A persistent misconception is that FND is a diagnosis of exclusion — what you are left with when the tests come back clear. It is not. FND is a rule-in diagnosis, made on positive clinical signs that demonstrate the inconsistency characteristic of the condition.

The best known is Hoover's sign for functional leg weakness: hip extension is weak when tested directly, but returns to normal strength when you flex the opposite hip against resistance. The muscle and its nerve supply are demonstrably working — which is the finding, not a trick. Tremor entrainment, where a functional tremor takes on the rhythm of a movement performed with the other hand, works on the same principle.

The diagnosis itself should be made by a neurologist or a doctor familiar with neurological examination. If you have not been assessed by one, that comes before physiotherapy, not after it — treating the wrong condition helps nobody. neurosymptoms.org, written by Professor Jon Stone in Edinburgh, is the standard patient resource and is worth reading before your first appointment.

The largest trial of specialist physiotherapy for functional motor disorder is Physio4FMD, a multicentre randomised controlled trial across 11 hospitals in England and Scotland, published in The Lancet Neurology in 2024. It compared a protocolised specialist physiotherapy programme against referral to standard community neurological physiotherapy.

The result was mixed, and it would be dishonest to quote only the good half:

• The primary outcome was not met. Specialist physiotherapy did not produce better self-reported physical functioning at 12 months than treatment as usual.
• Patient-rated improvement was substantially higher. At six months, 72% of the specialist physiotherapy group rated their symptoms as improved, against 18% of the comparison group.
• Measures of mental health favoured the specialist group, and both forms of physiotherapy were found to be safe and valued by patients.

The reasonable reading is that physiotherapy for FND is worth doing and helps a majority of people who try it, but that it is not a reliable cure and the trial evidence does not support promising one. Any clinic presenting FND physiotherapy as a straightforward fix is going beyond what the data will carry.

Standard neurological rehabilitation is built on repetition and effort — strengthen the weak side, practise the movement, increase the load. In FND, effortful concentration on the affected limb often makes the symptom worse, because attention directed at the movement is part of what is disrupting it. Treating FND with a stroke programme tends to fail, and the failure then gets read as the patient not trying.

The approach instead centres on:

• Explanation first. Understanding why the symptom happens and why it is reversible is part of the treatment, not the preamble to it. This is the step most consistently skipped.
• Redirecting attention. Movements are practised in ways that shift focus away from the affected part — automatic and whole-body tasks, dual tasking, rhythm and momentum — because normal movement often returns when it is not being watched.
• Retraining normal patterns rather than compensating around abnormal ones, so the aim is a normal walking pattern rather than a more efficient limp.
• Working with, not against, the diagnosis. Aids and supports are used cautiously; long-term reliance on a wheelchair or splint can entrench the abnormal pattern.

First appointments are 60 minutes, and a meaningful part of that is talking rather than exercising. Sessions run in clinic at Unit 28, Flexspace Bolton, or as home visits and video appointments.

Marcus is a physiotherapist with a Masters in Advanced Clinical Practice and experience in neurological rehabilitation. He is not a neurologist, psychiatrist or psychologist. FND is frequently managed best by more than one discipline, and where psychological therapy is the missing piece — which it often is, particularly where there is co-occurring anxiety, trauma or functional seizures — he will say so and suggest onward referral rather than working outside his scope.

Functional seizures in particular need a management plan led by neurology and psychology. Physiotherapy has a supporting role there, not a leading one.
