NCT06873698

Brief Summary

The goal of this pilot randomized clinical trial is to learn if Neurobehavioral Therapy (NBT) works to treat motor functional neurological disorder (mFND) (also referred to as functional motor disorder). The main questions it aims to answer are:

  • Does NBT lower mFND symptoms?
  • Does NBT lower common co-occurring symptoms and improve functioning? Researchers will compare NBT to standard medical care (SMC). Participants will be randomized to receive either:
  • 12 weekly sessions of NBT, along with their SMC,
  • or continue receiving their SMC as provided by their treating clinicians.
  • all participants. regardless of group assignment, will complete a total of five in-clinic visits at the following time points: Baseline, 6 weeks, 12 weeks, 8 Months and 12 Months for self-report surveys to assess functional status, quality of life and mFND symptoms.

Outcome Measures

Primary Outcomes (3)

  • SF-36 Health Survey (SF-36)

    The SF-36 is a 36-item self-report measure that assess 8 domains: physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions.

    Baseline, Week 6, Week 12, 8 Months and 12 Months

  • Psychogenic Movement Disorders Rating Scale (PMDRS)

    The PMDRS is a clinical assessment tool designed to measure the severity and characteristics of abnormal movements associated with psychogenic movement disorders (also called functional movement disorders), including details like the type of movement, affected body regions, duration, and functional impact of the symptoms, allowing clinicians to track changes over time and evaluate treatment efficacy.

    Baseline, Week 6, Week 12, 8 Months and 12 Months

  • Simplified Functional Movement Disorders Rating Scale (S-FMDRS)

    The S-FMDRS is a clinical tool used to assess the severity of functional movement disorders (FMDs) by evaluating the presence and intensity of abnormal movements in different body regions, including gait and speech.

    Baseline, Week 6, Week 12, 8 Months and 12 Months

Secondary Outcomes (12)

  • Generalized Anxiety Disorder (GAD-7)

    Baseline, Week 6, Week 12, 8 Months and 12 Months

  • Patient Health Questionnaire (PHQ-9)

    Baseline, Week 6, Week 12, 8 Months and 12 Months

  • Patient Health Questionnaire (PHQ-15)

    Baseline, Week 6, Week 12, 8 Months and 12 Months

  • Posttraumatic Scale Checklist-5 (PCL-5)

    Baseline, Week 6, Week 12, 8 Months and 12 Months

  • Global Assessment of Functioning (GAF)

    Baseline, Week 6, Week 12, 8 Months and 12 Months

  • +7 more secondary outcomes

Other Outcomes (2)

  • Abnormal Movement Log

    Baseline, [Weekly - NBT Arm Only], Week 6, Week 12, 8 Months and 12 Months

  • Status Survey

    Baseline, Week 6, Week 12, 8 Months and 12 Months

Study Arms (2)

Neuro-Behavioral Therapy

EXPERIMENTAL

Participants will receive neuro-behavioral therapy (NBT), in individual, weekly, one-hour appointments, using the 12 session, "Taking Control of Your Functional Movements: Workbook", over the course of 12 to 18 weeks. Before each appointment, participants will complete worksheets/questions in one chapter that will be discussed during the weekly virtual appointment. Video appointments will be completed using an encrypted healthcare weblink and will be digitally recorded for review to ensure therapy adherence and competence. Participants randomized to the NBT arm will also participate in 5 in-person visits for exam documentation.

Behavioral: Neuro-behavioral Therapy

Standard Medical Care

ACTIVE COMPARATOR

If randomized to this treatment arm, participants will continue to follow up with their clinicians while receiving standard medical care (SMC) and without receiving the study intervention. Research staff will ask about what care participants are receiving when they meet with staff. Subjects randomized to the SMC arm will participate in 5 in-person visits for exam and SMC documentation.

Other: Standard Medical Care (SMC)

Interventions

Neuro-behavioral therapy (NBT) is an evidence-based, multi-modality, time-limited, whole-person therapy, delivered in one hour, weekly, individual appointments. NBT has been used to treat epilepsy, nonepileptic (functional) seizures, and motor functional neurological disorder (mFND).

Also known as: Taking Control of Your Functional Motor Disorder Workbook
Neuro-Behavioral Therapy

Standard Medical Care (SMC) involves the routine care received by the participant. SMC may include any of the following evaluation and followup appointments with neurology, physiatry, psychiatry, psychology, mental health, rehabilitation (e.g., Physical Therapy, Occupational Therapy, Speech and Language Therapy), primary care, among other specialists.

Standard Medical Care
