What this Trial Is About
Researchers are examining whether daily physical activity, tracked remotely through a thigh-worn accelerometer, can reliably reflect symptom impact in people with Functional Neurologic Disorder (FND). This study aims to address limitations of current assessments that only capture a single moment and do not show daily symptom variations or functional effects. It will evaluate the feasibility of continuous activity monitoring, explore its relationship with established FND measures, and collect participants' personal experiences with daily activity. Participants will wear a thigh-mounted accelerometer continuously for about 7 days to measure various activity behaviors such as step count, sedentary time, and standing transitions. The study involves two groups: individuals with neurologist-confirmed FND and healthy controls matched for age and sex without major mobility-impacting diseases. After the monitoring period, participants will take part in interviews to share their experiences, which will be analyzed alongside the activity data. Throughout the study, researchers will assess adherence to wearing the device, retention rates, and acceptability of the procedures. Data collected include objective activity measurements and qualitative insights from interviews. The primary outcomes focus on feasibility indicators like enrollment success, adherence to device use, participant retention, and acceptability ratings. This study is conducted by the University of Colorado, Denver and lasts about one week per participant, with ongoing monitoring and assessments during this period.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Adults aged 18 to 65 years
- Neurologist-confirmed diagnosis of functional neurologic disorder with motor, sensory, dizziness, and/or seizure symptoms
- Healthy controls roughly matched to FND participants by age and sex
- Healthy controls free from major diseases affecting mobility, including neurologic, movement, cardiac, pulmonary, renal, and psychiatric disorders
You will not qualify if you...
- Physical or cognitive symptoms that impair ability to participate, such as having more than 10 seizures per day
- Diagnosis of other major neurologic, cardiovascular, musculoskeletal, or psychiatric disorders affecting mobility as determined by the principal investigator

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - 7 to 10 days
Participants wear a thigh-mounted accelerometer continuously for 7 days to remotely measure physical activity behaviors such as step count, sedentary time, and time spent standing and stepping.
2 visits; one at the start to receive the accelerometer and one approximately 7 days later for device return and assessments
Duration - At Visit 2 (approximately 7 days after Visit 1)
Participants complete clinician- and patient-rated assessments to compare with activity behavior data, and individuals with FND participate in semi-structured interviews to explore their lived experiences of activity behavior.
1 visit (in-person or remote) for assessments and interviews
