The goal of this clinical trial is to test a new treatment for adults with walking problems due to Functional Neurological Disorder (FND).
The main question the trial aims to answer is:
\- Is stimulation-enhanced physical therapy an effective treatment for walking problems due to FND?
Researchers will compare the stimulation-enhanced physical therapy to gold-standard physical therapy.
Participants will:
* Complete three in-person sessions on three consecutive days * Complete follow-up assessments by video call at 7 days, 30 days and 90 days after treatment
Clinically established diagnosis of FND or an equivalent term
Investigations are accepted as complete by the patient and treating physician
Walking difficulty that prevents crossing the road unaided at a traffic light pedestrian crossing
Lower limb functional weakness
Age < 21 years
Living with a parent or guardian who provides primary emotional support and assistance with most daily tasks
Medical instability precluding safe participation in physical therapy
Cognitive or communication impairment precluding informed consent or the ability to effectively engage in education aspects of the trial with family support
