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:
Researchers will compare NBT to standard medical care (SMC).
Participants will be randomized to receive either:
The study aims to enroll 40 participants at Rhode Island Hospital. 20 participants with Motor Functional Neurological Disorder (mFND) will be randomized to Neurobehavioral Therapy (Group 1) and 20 participants with mFND to Standard Medical Care (Group 2). Those randomized to neurobehavioral therapy will be asked to complete treatment sessions over the course of 12 to 18 weeks. Those in the standard medical care arm will continue to receive their routine care with their clinicians.
All participants regardless of group assignment, will complete a total of five in-person clinic visits at the following time points: Baseline, 6 weeks, 12 weeks, 8 Months and 12 Months. These visits will include the completion of interview questions and self-report surveys that will assess functional status, quality of life and mFND symptoms.
Please see the "Arms and Interventions" section to see a more detailed description of each group/arm.
The goal of this Clinical Trial is to investigate the feasibility and efficacy of Neuro-Behavioral Therapy in Individuals aged 18 to 100 diagnosed with Motor Functional Neurologic Disorder. The main questions this study aims to answer are:
Aim 1: Examine the feasibility, acceptability, and practicality of manualized Neuro-Behavioral Therapy (NBT) in Functional Neurological Disorder (FND).
Hypothesis 1: Manualized NBT will demonstrate feasibility through acceptability and practicality, defined as ≥80% of participants enrolling in the study will participate in the study measures (acceptability) and complete the entire study protocol (practicality), respectively.
Aim 2: Examine the preliminary effectiveness of manualized NBT in improving health-related quality of life and reducing the severity and disability of mFNDs, as measured by the SF-36 and PMDRS/S-FMDRS (primary outcome), respectively.
Hypothesis 2: NBT will show improvements in SF-36 scores and reductions in PMDRS scores. We will evaluate this by conducting a preliminary examination of the manualized NBT intervention, with a focus on interpreting effect sizes. We will also gather key statistics needed to inform a fully powered clinical trial, such as the standard deviation and pre-post correlation of the SF-36 and PMDRS.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 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. |
|
| 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. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Neuro-behavioral Therapy | Behavioral | 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). |
| Measure | Description | Time Frame |
|---|---|---|
| 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 |
| Measure | Description | Time Frame |
|---|---|---|
| Generalized Anxiety Disorder (GAD-7) | The GAD-7 is a 7 item self-report measure that assesses Anxiety severity from "0" (not at all) to "3" (nearly every day) on each question. The highest possible score is "21", relating to the highest severity of Generalized Anxiety Disorder. | Baseline, Week 6, Week 12, 8 Months and 12 Months |
| Measure | Description | Time Frame |
|---|---|---|
| Abnormal Movement Log | The Abnormal Movements Log is a daily diary to track unusual movements over the course of a week. Each day, individuals will record a series of details in relation to their mFND such as the number, duration, time, body parts affected, type of movement, severity (mild, moderate, severe), triggers, warning signs, what helps, and how it impacts themselves and others. The Principal Investigator will review the movement logs during study visits to better understand ones symptoms and how impactful they are one ones day. It's a simple tool aimed to identify patterns and improve care. |
