What is the general prognosis for FMD?

▪️~80% stay symptomatic
▪️Higher than expected mortality (~11%)

Why might FMD be associated with an increased risk of premature death?

Lifestyle factors (e.g. sedentary and dependent on wheelchair, cardiovascular disease)

Other associated secondary factors

Perfectly

What is the biopsychosocial understanding of FMD?

Disorder of sensorimotor processing (predictive processing)

Top-down expectations distort bottom up somatosensory experiences

Top-down ______________ distort bottom-up _____________________

▪️Expectations
▪️Somatosensory experiences

How well did you know this?

Perfectly

What facilitates the disruption between expectation and somatosensory experience?

Excessive attention directed towards the body

Hence they can be distracted and redirected

Biological, psychological, and social events can act as…

▪️Risk factors
▪️Triggering factors
▪️Maintaining factors

What is the gold standard for FND management?

Multidisciplinary care

What are the main barriers to FND care?

▪️Misdiagnosis is common
▪️Only ~30 specialist services in UK

What are the 6 main components of physical rehabilitation for FND?

▪️Education
▪️Movement retaining
▪️Addressing secondary problems (e.g. pain, fatigue)
▪️Self-management
▪️Vocational rehab
▪️Follow-up

What are some of the main targets for physical rehabilitation?

▪️Retraining attention
▪️Change expectations and illness beliefs
▪️Address fears of falling
▪️Improve pain management
▪️Address soft tissue problems
▪️Improve physical fitness
▪️Psychosocial benefits of activity
▪️Change maladaptive behaviours

What is the first key step to FND treatment?

Education!

▪️Acknowledge and explain the problem
▪️Explain how diagnosis was made
▪️Explain how attention drives it
▪️Discuss risk factors
▪️Explain how treatment works
▪️Language is key!

What can movement and posture retraining be used for?

Addressing maladaptive habitual postures

How might maladaptive habitual postures arise?

▪️Schema of body changes when sat in a position for a long tiken ▪️May lose insight and believe they're say normally if eyes are closed

What approach is usually taken with movement retraining?

Sequential motor learning E.g. help one element of walking then another, building up

What techniques can be used for movement retraining?

▪️Sequential motor learning ▪️Get them to think about moving differently to direct focus of motor attention ▪️Mirror feedback

How does mirror feedback work for movement retraining?

Redirects attention from the internal self into the external self/environment

What percentage of FMD cases show improvement with movement retraining?

40%

What is self-management?

Tasks one must undertake to live with their condition (e.g. medical, emotional etc.)

What can be used to help with self-management of FND?

Rehabilitation workbooks ▪️Info on FMD ▪️Reflections from treatment ▪️Management strategies ▪️Plans for managing difficult days ▪️Chart progress ▪️Future goals

Why mignt TMS show benefit alongside treatment for FND?

Placebo

What can be used alongside regular management strategies?

▪️Management of other symptoms e.g. pain, fatigue ▪️EMG biofeedback ▪️Therapeutic sedation ▪️TMS ▪️Hypnosis ▪️Group interventions

What is the evidence for treatment adjuncts for FND?

Very little

What should you avoid with FND treatment?

▪️Passive treatments ▪️Adaptive aids ▪️Focus on impairments ▪️Neglecting secondary factors (e.g. fatigue, pain)

What should be encouraged during FND treatment?

▪️Focus on activities ▪️Redirection of attention ▪️Maximum independence ▪️Family involvement ▪️Maintenance and relapse prevention plans

Why should splints and aids generally be avoided?

▪️Can affect illness beliefs and movement patterns. ▪️Can cause secondary sources of pain. ▪️Can draw more attention to an area - symptoms exacerbation and maintenance!

What should you do if aids are not avoidable?

▪️Involve patient in decision making and document it ▪️Ideally maintain thought that this is a temporary solution ▪️Keep the opportunity for patients to move without it

Should casting me used in fixed dystonia?

Not really - immobilisation can be very harmful, maintaining illness belief so should be avoided

According to a large systematic review of physiotherapy for FND, what are it's main outcomes?

▪️55-70% 'good' ▪️Moderate to large effect ▪️Some loss of effects but benefits largely sustained 1-2 years later (unclear after that) ▪️Little change for mental health

What were the main findings of Czarnecki's 2012 evaluation of a 5-day intensive OT and PT treatment?

▪️69% rated markedly improved ▪️60% at follow up

What are the main limitations of the evidence for physical rehabilitation in FND?

▪️Most selected for treatments are less severe - exclusion of those with dominant pain, fatigue or psychiatric comorbidity) ▪️Unclear how long benefits stay ▪️Unclear data on return to work

What did Jordbru (2014) find in their study of a 3 week inpatient rehab for functional gait?

▪️Physical activity combined with educational and cognitive behavioural frame ▪️Significant difference in functional mobility ▪️Benefit sustained at 12 month follow up

In Nielsen's feasibility study of PT in FMD, how many showed improvement of some kind?

71% in intervention compared to 19% in control

In Nielsen's feasibility study of PT in FMD, what domains of the SF 36 show most improvement?

▪️Physical function ▪️Physical role ▪️Social function

In Nielsen's feasibility study of PT in FMD, what domains of the SF 36 did NOT show change?

▪️Bodily pain ▪️General health ▪️Mental health (as well as HADS) ▪️Vitality ▪️Emotional role

How do physical interventions appear to effect illness perception and threat value?

Improves it as they are attending less to the problem/body part (decreased threat value)

What are the three main goals of physical rehabilitation in FND?

▪️Education (beliefs and expectations) ▪️Movement retraining with redirection of attention ▪️Teaching self management strategies
