Functional Neurological Disorder Rehabilitation: What Physical and Occupational Therapy Actually Look Like in 2026

A 34-year-old woman is referred to outpatient PT three months after twisting her ankle. The ankle imaging was unremarkable. The leg, however, has progressively weakened to the point where she uses a wheelchair. Her quad and hip strength test at 0 out of 5 on direct manual muscle testing. When you do a Hoover's sign (testing contralateral hip flexion with your hand beneath her affected heel), strong downward pressure appears. The motor pathway is intact. The signal isn't reaching where it needs to under conscious effort.

This is functional neurological disorder. Functional neurological disorder rehabilitation is not what most non-specialist clinicians were taught. It is not "wait for psychiatry." It is not "she'll need compensatory devices." It is a structured, evidence-based PT and OT intervention with a randomized controlled trial base.

The reason this patient does not improve on a standard stroke-style strengthening protocol is that her motor pathways are not damaged. They are intact, and the issue is at the network level: abnormal top-down predictions, attention-motor coupling, and dysregulated brain network function. Which means the rehabilitation has to operate at the network level too.

The Research Tension

The largest piece of evidence on FND physical therapy is the Physio4FMD trial, a pragmatic multicenter phase 3 RCT conducted across England and Scotland that randomized 355 adults with functional motor disorder to specialist physiotherapy or community-based neurological physiotherapy. The intervention was nine sessions plus a follow-up, delivered by PTs trained specifically in FND management.

The primary outcome (SF-36 physical functioning at 12 months) did not reach statistical significance (both arms received active PT), but several secondary outcomes did. Significantly more participants in the specialist arm self-rated their motor symptoms as improved. Mental health and subjective well-being were better. No serious adverse events were associated with the intervention. The trial established that PT is safe, acceptable to patients, and effective when delivered with FND-specific knowledge.

This sits alongside three other pieces of recent evidence:

• The Macías-García RCT compared combined PT plus CBT to psychological support alone in functional movement disorder. The combined arm produced significantly greater SF-36 PCS and MCS improvements at 5 months. Integration of physical and psychological treatment beats either alone.
• Systematic reviews of CBT for FND consistently show medium-sized benefits across physical symptoms, mental health, and function, particularly strong in functional seizures.
• Multidisciplinary outpatient programs (5–8 week structured curricula combining PT, OT, CBT, and psychoeducation) produce significant pre-post improvements in anxiety, depression, functional impairment, and mobility, sustained at three-month follow-up. The transdisciplinary ambulatory model has been associated with reduced emergency department presentations.

The clinical implication is that FND-specific physical therapy works, but only when the clinician knows that FND-specific physical therapy is structurally different from what they were trained to do. Strengthening exercises for functional weakness do not work, because the muscle is not weak. Compensatory strategies (mobility aids, adaptive devices) can perpetuate the illness model and the disability. The work is in distraction, redirection of attention away from the affected body part, and the demonstration that automatic movement is preserved.

What This Means in Practice

For Physical Therapists

The non-negotiables: redirect attention away from the affected limb, engage the patient in dual-task or cognitive load activities during motor work, use novel motor tasks (walking backward, varied rhythm) to bypass entrenched abnormal patterns, and demonstrate preserved function during examination as therapeutic education. The Hoover's sign isn't just diagnostic. It's a teaching moment. The patient watches their leg activate.

Graded retraining moves from simple to complex with attention always on the task goal, never on the symptomatic body part. Weight-shifting in sitting → standing weight shifts → stepping → walking, with each stage built on demonstrated capability rather than against perceived weakness. The Physio4FMD intervention parameters (nine sessions with FND-specific training) are a useful real-world benchmark.

For Occupational Therapists

OT in FND addresses what the symptoms actually do to daily life (the patient who can't dress, can't return to work, can't manage the household) through sensory modulation, functional goal-setting, and graded reintegration to valued occupations. The Canadian Occupational Performance Measure structures the goals around what the patient actually wants to do, not against generic functional benchmarks.

Sensory profile assessment (Adolescent/Adult Sensory Profile) identifies the modulation patterns that may be amplifying symptoms. Environmental modifications, energy conservation, and structured engagement in meaningful activities matter as much as motor work for this population.

For Athletic Trainers

ATCs see FND most often as overlapping presentations with post-concussion, after acute injury, or in tactical athletes where the symptom pattern doesn't match the imaging or physical exam. The recognition role is the primary scope: knowing what positive signs look like, distinguishing FND from organic emergency, and triaging to the appropriate multidisciplinary referral pathway.

Return-to-play decisions for athletes with mixed organic and functional presentations are nuanced and benefit from coordination with neurology and rehabilitation specialists. The course's positive-signs framework gives ATCs a vocabulary for that triage.

For Massage Therapists

MTs see FND in clients with persistent unexplained symptoms who have been dismissed by their physicians. The most valuable MT contribution is the validation that the symptoms are real, paired with a referral pathway that doesn't dismiss the client. Soft tissue work is symptom-supportive, not curative. The recognition that "your symptoms are real, and there's a name for what you have, and there's a treatment pathway" can be the moment that changes a client's relationship with their condition.

Where the Evidence Is Still Developing

Several pieces are not yet settled. The optimal balance of physical and psychological intervention varies by patient, and there is no validated stratification rule. The Macías-García trial favors combined PT and CBT for functional movement disorder, but the dosing and sequencing across subtypes (motor vs. seizure vs. cognitive vs. sensory) is still being worked out.

Emerging therapies are promising but preliminary. Transcranial magnetic stimulation has shown signal in uncontrolled and small RCT studies but needs large sham-controlled trials. EMDR (the MODIFI feasibility trial) demonstrated reductions in PTSD, depression, anxiety, dissociation, disability, and healthcare utilization, but that's feasibility data, not definitive efficacy. Both are reasonable adjuncts when standard multidisciplinary care has plateaued.

And the population most underserved is the chronic, severe presentation with multiple comorbidities and entrenched disability. Intensive inpatient programs produce meaningful gains in this group, but access is limited and the evidence base for outpatient management of this subgroup is thinner.

Three Things You Can Do This Week

1. Learn Hoover's sign and one other positive sign properly. Practice them on colleagues, watch them performed on video, and start incorporating them into your motor exam for any patient with weakness that doesn't follow a clear anatomic pattern. Specificity is high (90–100%) when done correctly. The full positive-signs diagnostic framework covers the dozen most useful.
2. Replace strengthening cues with distraction cues for any patient you suspect has FND. Instead of "push against my hand," cue "count backward from 100 by sevens while you reach for the cone." Watch what changes. The patient's intact motor system often reappears when conscious effort releases. This is also a teaching moment: the patient sees their own preserved capability.
3. Coordinate the diagnostic communication with whoever is making the formal diagnosis. The way the FND diagnosis is communicated influences outcomes more than almost any other variable. Patients who hear "we found specific signs that tell us this is functional, here's what we're going to do" engage differently than patients who hear "we ruled everything out." See how the diagnostic conversation becomes the intervention.

The Ridley Learning clinician's guide for this condition pulls Physio4FMD, the positive-signs framework, multidisciplinary care models, and the diagnostic communication evidence into one operating model with the discipline-specific layer underneath. The Physio4FMD trial breakdown covers the dosing and parameters in more depth.

The Bottom Line

Modern functional neurological disorder rehabilitation is structured, evidence-based, and structurally different from what most rehabilitation clinicians were trained to do. The motor pathways are intact, so distraction, automatic movement, and graded retraining are the core, not strengthening or compensation. The Physio4FMD trial established that PT-led intervention is safe and effective when delivered with FND-specific knowledge. The patient sitting in your clinic next week with weakness that doesn't follow a clear anatomic pattern deserves the FND-specific algorithm, not the one built for a different diagnosis.
