This study evaluates whether remotely measured daily activity behavior, captured through a thigh-worn accelerometer, can serve as a reliable and ecologically valid indicator of symptom impact in individuals with Functional Neurologic Disorder (FND). Current clinician-rated assessments capture only a single time point and do not reflect day-to-day symptom variability or functional impact. The study will (1) assess the feasibility of continuous activity monitoring in people with FND, (2) examine associations between activity behavior and established clinician- and patient-reported FND measures, and (3) qualitatively explore participants' lived experiences of daily activity. Findings aim to address a critical gap in understanding real-world function in this heterogeneous population.
Roughly matched to participants with FND for age and sex
Free from major disease that affects mobility (e.g., neurologic, movement, cardiac, pulmonary, renal, and psychiatric disorders) by history.
Physical or cognitive symptoms impairing ability to engage with the protocol (e.g., seizure frequency > 10/day).
Diagnosis of other major neurologic, cardiovascular, musculoskeletal, or psychiatric disorder that affects mobility as determined by the principal investigator
