Body Signal Integration Training: A Case Series

Functional Neurological Disorder

The goal of this clinical trial is to learn about an intervention package in individuals with Functional Neurological Disorder (FND). The main questions it aims to answer are: Is the intervention package acceptable to and feasible to deliver to individuals with FND? Does the intervention package improve symptoms of FND? Participants will be asked to engage in 8 weekly sessions of an intervention aimed to improve the perception of signals coming from the body (interoception). Participants will be asked to complete tasks between session practising tuning into signals from the body. Participants will also be asked to complete questionnaires measuring their psychological wellbeing, FND symptoms and interoception.

Metacognitive Therapy and Neuro-physiotherapy as a Treatment for Functional Movement Disorders

Conversion Disorder

Patients with functional movement disorders (FMD) present with abnormal movements incompatible with symptoms of well-defined neurological disorders and are not associated with structural abnormality of the nervous system. FMD are very common. However, the pattern of care of these patients is highly inconsistent and most patients feel dissatisfied with the treatment they receive. One reason for this unsatisfactory scenario is that there are no generally accepted therapeutic guidelines for FMD. Therefore, treatment strategies are urgently needed. Recent neurophysiological studies suggest common underlying disease mechanism across FMD patients, particularly abnormal allocation of attentional resources. Conceptually, this calls for therapeutic approaches, in which attention re-focusing is trained. In this respect, neuro-physiotherapy (NPT) is based on the physical movement retraining by demonstrating that normal movement is possible, to facilitate patients' confidence into the own movement capacity. Based on the current literature, the investigators suggest that NPT is a feasible and effective treatment options in FMD population. However, the proportion of patients fully accepting and improving from NPT was limited. FMD patients might be more receptive to NPT if additional specialized psychotherapy approaches, e.g., metacognitive therapy (MCT) is offered. MCT focusses on patients believes about their own mind and cognition (metacognition). It explains how dysfunctional patterns of thinking and self-awareness can lead to and maintain FMD and in particular trains patients to consciously (re-)focus their attention away from unpleasant or disturbing mental processes. Thus, the investigators aim to analyze, in addition to NPT only, the feasibility and treatment efficacy of a combination of NPT and MCT. The investigators will apply therapy frequently (2 times 1 hour sessions per week over 10 weeks) and patients will be instructed for an additional home-based training. Effectiveness will be analyzed up to 12 month after the intervention by validated, FMD-specific, blinded video ratings. Importantly, FMD patients have been shown to have the potential for a full recovery if sufficient treatment is applied. Therefore, the therapeutic approaches of the clinical feasibility trial, if successful, are expected to have immediate and strong impact on the care of FMD patients including an improvement in quality of life, and to reduce health care system burdens.

CBT Training for Cognitive Reappraisal as an Intervention for Patients With Functional Tremor -...

Functional Movement Disorder

The aim of this psychological study is to evaluate the effect of a cognitive behavioral therapy (CBT) intervention aimed at improving cognitive reappraisal on (1) Clinical and Self-Rated Health according to Patient Global Impression-Change (PGI-C), Patient Global Impression-Severity (PGI-S), Clinical Global Impression-Change (CGI-C) and Clinical Global Impression-Severity (CGI-S) after 4 weeks, (2) the change in the severity of the functional movement disorder/tremor as assessed by a blinded clinician using the Simplified Version of the Psychogenic Movement Disorders Rating Scale (S-FMDRS) after 4 weeks and (3) the change in the severity of functional tremor assessed via the Fahn Tolosa Marin Tremor Rating Scale (FTM) after 4 weeks. The knowledge gained about the introspective and neurobiological effect of this cognitive behavioral therapy intervention should enable improved therapy options for patients with functional tremor / functional motor disorders in the future.

Modulation of Sense of Agency With Non-invasive Brain Stimulation and Mindfulness-based Stress Reduction...

Functional Neurological Symptom DisorderNeurological Diseases or Conditions

A conversion disorder is a dysfunction of the nervous system in which no structural damage can be demonstrated. However, it must be distinguished from other psychiatric disorders such as psychosis or depression. There are a variety of signs of the disease, such as muscle paralysis, uncontrolled tremors or cramps. In rarer cases, blindness, deafness or numbness may occur. Diagnosing this complex disorder has always been a challenge for neurologists and psychiatrists. This study investigates the effects of transcranial magnetic stimulation (TMS) on the general well-being and symptoms of conversion disorder and other neurological disorders and in comparison to healthy subjects. The TMS method allows to target specific areas of the brain by means of magnetic fields. This technique is not painful and does not have long-lasting effects. In addition, the study investigates the effects of mindfulness-based stress reduction on the general well-being and symptoms of conversion disorder and other neurological disorders and compared to healthy subjects. This technique is not painful and has no long-lasting effects. Furthermore, the study examines movement patterns and symptoms of patients compared to healthy controls while they are in a virtual reality. Finally, the study examines patients' brain activity while playing a game targeting the sense of agency in real time, which is recorded with an MRI scanner. The study includes a maximum of twelve sessions in total (ten sessions of approximately 1.5-2 hours each and two sessions each overnight). The planned study methods include TMS, (real-time and normal) magnetic resonance tomography of the brain (MRI "tube"), virtual- and augmented reality (AR/VR), questionnaires, blood, saliva, and motion sensors (e.g., fitness bracelet), and participation in the 8-week mindfulness program.

Mirror Therapy Rehabilitation for Motor Functional Neurological Disorders.

Functional Neurological Symptom Disorder

Motor functional neurological disorders (FND) correspond to motor symptoms that are unexplained by an organic lesion but are due to cerebral dysfunction. Patients with these disorders have high rates of disability and health care utilization, and their quality of life is as impaired as that of patients with an "organic" disease. Accompanying these patients in their often-complex health journey represents a socio-economic and human challenge that demands interdisciplinary collaboration. Rehabilitation is seen as an important part of the therapy for motor FND. However, further research is needed to refine appropriate interventions and to create evidence-based recommendations. In this study, patients suffering from a functional neurological motor disorder of the upper limb will be included in a novel rehabilitation protocol that includes computerized mirror therapy. The study will used a multiple baseline, across subjects, single-case experimental design (SCED). In this type of design, each subject is his own control, with individual parameters being repeatedly measured in the presence and absence of the intervention of interest (computerized mirror therapy). Computerized mirror therapy could restore the coherence between the motor program and its execution. The investigators hypothesize that this process could re-normalize upper-limb motor activity and that this will have a beneficial impact on manual dexterity, quality of life, and mental representation capacities of the upper limb. The objective of this project is to use the single case experimental design method to investigate the efficacy of rehabilitation with computerized mirror therapy for patients suffering from motor neurological disorders (FND) of the upper limb.

Telemedicine in Functional Motor Disorder

Functional Movement Disorder

Functional motor disorders (FMDs) are a broad spectrum of functional neurological disorders, referring to abnormal movements like dystonia, tremor, and gait/balance disorders. Patients with FMDs experience high degrees of disability and distress equivalent to those suffering from degenerative neurological diseases. Rehabilitation is essential in managing FMDs. However, the current systems of rehabilitation delivery face two main challenges. Patients are not receiving the amount and kind of evidence-based rehabilitation they need due to the lack of rehabilitation professionals' experts in the field. The rehabilitation setting is not adequate for the long-term management and monitoring of these patients. To date, no randomized controlled trials are evaluating the effectiveness of Telemedicine in the management of patients with FMD. This is a single-blind randomized-controlled trial (RCT) with 2-parallel arms to demonstrate the effectiveness and superiority of a 5-day intensive rehabilitation treatment followed by a telemedicine program on the motor, non-motor symptoms (pain, fatigue, anxiety, and depression), the self-perception of clinical change and Health-Related Quality of Life, and health care costs in patients with FMDs.

Efficacy of Dorso-lateral Prefrontal Cortex Stimulation by tDCS in Motor Conversion Disorder Patients...

Conversion Disorder

Conversion disorder refers to impaired voluntary motor or sensory functions that are not compatible with a well-known neurological condition. This disorder affects up to 30% of hospitalized patients in neurology departments and symptoms persist in 35% of patients after 12 years of evolution. Despite a poor prognosis, no treatments have been validated to date. The development of non-invasive brain stimulation techniques has allowed the creation of treatments focused on dysfunctional brain regions associated with motor conversion disorder. Hypoactivation of prefrontal dorso-lateral cortex underlies the course of functional motor symptoms. Results of the HYCORE study conducted at Nîmes University Hospital (including 20 patients, clinicaltrial.gov NCT02329626) confirmed these results and related hypoactivation of PFDLC to persistent motor disability at 3 months and 6 months follow-up. Activation of the PFDLC could restore executive control and thus promote the recovery of motor symptoms. However, in most repeated Transcranial Magnetic Stimulation (rTMS) the primary motor areas were targeted and the clinical improvement was related to self-suggestion induced by the motor response produced. Among the different techniques, transcranial Direct Current Stimulation (tDCS) is a medical neuromodulation device that delivers a direct, low-intensity electric current to cortical areas, facilitating neuronal activity. Recently, PFDLC stimulation via tDCS has been used to treat several neuropsychiatric disorders and shown to be effective in depression. In addition, this technique has several advantages compared to rTMS: its use is simpler and costs 5 to 8 times less, the device is portable and there is no titration procedure. The tolerance of the tDCS is also better with no risk of epileptic seizure, neuronal depolarization being absent.

Non-invasive Intermittent Theta Burst Stimulation of the Dorsolateral Prefrontal Cortex in Functional...

Functional Movement Disorder

Background: Functional movement disorders (FMD) involve involuntary movements that are not due to a recognized neurological or medical cause. FMD can cause major disability. Researchers want to learn more to create better treatments for FMD. Objective: To test whether non-invasive brain stimulation using transcranial magnetic stimulation (TMS) improves FMD symptoms. Eligibility: People between the ages of 18 and 80 who have been diagnosed with FMD by a neurologist. Design: Participants will be randomly assigned to one of two groups. One group is an active brain stimulation group and the other is a sham brain stimulation group. Participants will have a baseline visit. This will include: Neurological exam Questionnaires Urine test Brain MRI: Participants will lie in a machine that takes pictures of the body. They will be asked to respond to images on a screen while in the scanner. Within 2 weeks of the baseline visit, participants will begin 5 daily sessions of TMS. The active group will have stimulation delivered to the brain via a coil. In the sham group, a dummy coil will be used that will not deliver stimulation. A total of three 3-minute cycles will be done in one visit. There will be 20-minute breaks between the cycles. Participants will have visits 1 month, 2 months, and 6 months after their last day of TMS. Their FMD symptoms will be evaluated. They will complete health questionnaires. These visits can be in person or virtual.
