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.
