Functional Neurological Disorder (FND) is increasingly recognised as a treatable condition, with
rehabilitation emerging as a central therapeutic approach. However, global rehabilitation models vary
widely, and outcome measurement remains inconsistent. This structured evidence synthesis summarises
international rehabilitation programs for FND and maps the outcome measures used to evaluate them
against recommended FND outcome domains. Using predefined eligibility criteria, the review integrates
findings from existing systematic reviews, randomised controlled trials (RCTs), and representative cohort
studies. Intensive physiotherapy and occupational therapy programs demonstrated consistent pre–post
improvements in motor symptoms and functional mobility. Multidisciplinary outpatient programs showed
moderate improvements across symptom severity, mobility, mood, and quality of life. The strongest causal
evidence came from an RCT demonstrating that combined physiotherapy and cognitive behavioural
therapy significantly improved quality of life and symptom outcomes compared with psychological
support. Outcome measures varied widely, though many aligned with recommended domains such as
symptom severity, disability, quality of life, psychological distress, and global impression of change.
Rehabilitation is effective for FND across multiple international models, though methodological
heterogeneity and inconsistent outcome measurement limit comparability. Adoption of standardised
outcome domains and validated tools is essential to strengthen future research and support scalable,
evidence based rehabilitation pathways.
