A Scoping Review of Measures Used to Assess Stress-Related Motor Dysfunction in Functional Movement Disorder.

ABSTRACT: Functional Neurological Disorder (FND) is a complex condition characterized by a range of motor and non-motor symptoms, including tremors, dystonia, sensory disturbances and dissociative episodes. Functional Movement Disorder (FMD), a common motor subtype of FND, specifically involves abnormal involuntary movements without an identifiable structural or organic cause. There isn't a validated assessment tool that currently exists to measure the specific impact of stress on motor symptom variability in FMD. The absence of such tools presents a barrier to accurate diagnosis, treatment planning, and longitudinal monitoring. This review focuses specifically on the FMD subtype, as it represents the most relevant phenotype for assessing stress-related motor dysfunction in the context of movement d
