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.
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 70 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.

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).
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.
Rhode Island Hospital
Providence, Rhode Island, United States
RECRUITINGSF-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.
Time frame: 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.
Time frame: 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.
Time frame: Baseline, Week 6, Week 12, 8 Months and 12 Months
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.
Time frame: Baseline, Week 6, Week 12, 8 Months and 12 Months
Patient Health Questionnaire (PHQ-9)
The PHQ-9 is a 9-item self-report measure instrument that assesses the severity of Depression on a scale from "0" (not at all) to "3" (nearly every day). The maximum score is 27.
Time frame: Baseline, Week 6, Week 12, 8 Months and 12 Months
Patient Health Questionnaire (PHQ-15)
The PHQ-15 is a 15-item self-report measure instrument that assesses the presence and severity of somatic symptoms on a scale from "0" (not bothered at all) to "2" (bothered a lot). The maximum score is 30.
Time frame: Baseline, Week 6, Week 12, 8 Months and 12 Months
Posttraumatic Scale Checklist-5 (PCL-5)
The PCL-5 is a 20-item self-report measure that assesses the presence and severity of PTSD symptoms.
