Filter by:The goal of this observational study is to assess movement in individuals with Myotonic Dystrophy Type 1 (DM1) and Type 2 (DM2) using digital biomarker tools. The long-term aim of this study is to incorporate these outcomes into clinical trials of DM1 and DM2 therapies. Participants will complete a series of assessments that allow for researchers to measure hand myotonia and walking quality, including a Video Hand Opening Test (VHOT), grip strength, 10 meter walk/run test, 6 minute walk test, Timed Up and Go (TUG), Motor Function Measures-32 (MFM-32) test, and more. These assessments may be recorded to detect and map participants motion and walking patterns. Several patient reported outcome (PROs) questionnaires will also be recorded. Participants may also be asked to monitor exercise and sleep activity at home using an Actigraph wearable device. This study is divided into 2 parts: Part A consists of a single visit. Part B consists of a 1-year longitudinal study with 3 clinical follow-up visits.
Myotonic dystrophy is associated with central sleep apnea, excessive daytime sleepiness, diminished working memory, impaired visuospatial skills, and deficits in problem-solving skills. Cerebrospinal fluid (CSF) is a clear, colorless fluid that surrounds and protects the brain. Changes in the composition of CSF can serve as early indicators of changes in brain activity and function. The purpose of this research is to learn about myotonic dystrophy by examining cerebrospinal fluid and brain activity in participants. The tests will be low risk and are well tolerated. The information that we gather from this study may help us evaluate, prevent, diagnose, treat, and improve our understanding of myotonic dystrophy
Myotonic dystrophy type 1 (DM1) is a neuromuscular disorder in relation with an unstable expansion of CTG repeat. Patients with DM1 are at risk of arrhythmia and conduction disorders. Mortality are mainly related to respiratory failure and sudden death. Patients with DM1 may suffer from obesity, arterial hypertension, diabetes mellitus and sleep apnea. These comorbidities are classically associated with left ventricular diastolic dysfunction (DD) . The investigators aim to assess the prevalence of left ventricular diastolic dysfunction in patients with myotonic dystrophy type 1 , the distribution of DD grading as well as the long-term prognosis of DM1 patients with a left ventricular diastolic dysfunction.
The ability of an individual to conceive some alternative representations and to behave in a flexible manner would emerge from preschool age and drastically improve between the ages of 3 and 5 (Doebel and Zelazo, 2013). They constitute, according to Diamond (2013), a prerequisite for the development of the Theory of Mind (ToM). Deficits in Executive Functions (EF) may therefore interfere with the child's ability to understand and adapt to social situations. Treatment failures are often observed when traditional cognitive tools are used. This would be linked to the divergence between non-immersive tests and situations encountered in everyday life (Damasio, 1994; Priore Castelnuovo and Liccione, 2002). For this reason, an increasing number of researchers are using virtual reality for the rehabilitation of executive functions and Theory of Mind in patients with neurodevelopmental pathology (Millen, Edlin-White and Cobb, 2010) or brain damage (Le Gall, Besnard, Louisy, Richard and Allain 2008). There is currently no systematic evaluation of ToM in children with the infantile form of DM1 even though these abilities are considered particularly vulnerable and have a decisive impact on the subsequent development of interpersonal relationships. This research will focus on studying the socio-emotional disorders associated with the infantile form of Myotonic Dystrophy type 1 (DM1). The axis that we propose to develop more specifically will be an interventional study with the aim of remediation with children from 5 to 16 years old suffering from the infantile form of DM1 via a training protocol in low-immersion Virtual Reality (VR) centered on emotional processing and theory of mind.
The combination of short quantitatively assessing muscular function and balance in combination with short clinical scores, can be a new valid approach to evaluate the patient risk of fall and help to create a quick checkup test to prescribe an appropriate assistive device. The primary goal of this project is to provide a short battery of clinical assessments used to determine risk of falling for patients with neuromuscular diseases (NMD) based on correlation between clinical assessments between two groups of NMD patients and scales used to assess risk of falling for patients.
The goal of this observational study is to learn about swallowing difficulties (dysphagia) in patients living with myotonic dystrophy type 1 (DM1). The main questions it aims to answer are: - whether the size and structure of the muscles involved in swallowing differ to those without the disease - how the size and structure of muscles may associate with swallowing function and swallowing symptoms in this group. Participants will undergo a range of tests including: - Ultrasound (US) assessment of the muscles involved in swallowing - An x-ray swallowing study (known as videofluoroscopy) - Assessment of swallowing symptoms, including questionnaires - Assessments of mobility, activity and breathing - Assessments of quality of life and wellbeing
Nearly two-third of patients with myotonic dystrophy type 2 (DM2) report that impaired cognition is among the most disabling symptoms and deeply affects their quality of life. Yet, relatively little is known about how DM2 affects brain structure and cognitive function as brain imaging studies in DM2 are extremely limited. This is a prospective, cross-sectional study of brain structure and function on cognitive and motor performance in patients with DM2 compared to healthy controls. All participants will undergo magnetic resonance imaging (MRI) to evaluate brain structure and white matter integrity, a comprehensive battery of cognitive and motor measures, self-reported questionnaires, and blood collection for brain-based biomarker analysis. A subset of participants will undergo lumbar puncture for cerebrospinal fluid (CSF) collection for additional biomarker analysis and validation. This work is critical to inform the development of rigorous clinical trial designs and plan for a longitudinal study to evaluate MRI measures as imaging biomarkers of disease progression and therapeutic response in DM2.
Myotonic dystrophy type 1 (DM1) is a rare genetic disease that affects about 1 in 2100 people. Patients diagnosed with DM1 present with many symptoms, however, their muscles are mainly affected. DM1 patients experience a gradual loss of muscle, followed by an increase in body fat percentage, which makes them weaker, resulting in difficulties to perform activities of daily living, such as climbing stairs, and understandably, this affects their quality of life. DM1 currently does not have a cure. Therefore, it is very important to find ways in which we can help DM1 patients to improve their symptoms, and hopefully, improve their quality of life, and possibly improve disease prognosis. Exercise is known to improve muscle quality and function. In addition, we hypothesize that a multi-ingredient supplement (MIS) for muscle health and antioxidants for fat loss, might show improved benefits on top of exercise. Therefore, we will investigate the effects of 16-week home-based concurrent training, with MIS or placebo, on body composition, and functional measures. Lastly, we will investigate muscle adaptations in DM1 and following study intervention
The study design is a prospective cohort study. It aims to evaluate the neuromuscular junction in dystrophic myotonia 1 (DM 1) using low-frequency repetitive nerve stimulation (RNS) on several nerve-muscle pairs of the one side including proximal and distal muscles of upper and lower extremities. First, it will be investigated whether a decrement with 3 Hz stimulation, as described in literature, is reproducible in our patient population. If this is the case, it will be examined whether it is the consequence of a dysfunction of the neuromuscular junction or rather linked to a hypo-excitability of some muscle fibers due to myotonia. For this purpose, additional tests including short exercise test (to observe any decrement resulting from an inexcitability in myotonic muscle fibers) and needle EMG (for mapping myotonic discharges in the muscles tested with repetitive nerve stimulation) will be performed. Single fiber-EMG will not be provided in this study as an abnormal result does not necessarily indicate a dysfunction of the neuromuscular junction but could just as well be due to the muscular dystrophy in the context of DM1. Finally, it will be investigated if there is a correlation between the decrement with 3 Hz stimulation and clinical signs as fixed muscle weakness (via Medical Research Counsil (MRC) scale, DM-activ scale [30]) and fatigue (via MG-ADL scale).
Myotonic Dystrophy type 1 (DM1) is a genetic multisystem disease causing muscle weakness and myotonia. As a result, upper limb function might become impaired. There are little research regarding rehabilitation and exercise for upper limb function in DM1. It is known from research on lower limb function in DM1 and other muscular dystrophies, that there are possibilities to improve function also in these deteriorating diseases. In this single subject experimental design study, 6-10 adults with DM1, who are at an inpatient rehabilitation center, will get intensive, but personally adapted senso- and robot assisted rehabilitation for arm- and hand function with Tyromotion Amadeo and Armeo Senso. These devices have previously been used in rehabilitation research for other neurological conditions. The participants will be followed up, and evaluated at a weekly basis, using video consultations. Fine motor skill dexterity test (9HPT) and the Nut and Bolt test will be used, and active range of motion (ROM) and muscle strenght and movement of upper limb will be measured. Furthermore, patient reported outcome measures (PROMS) on hand impairment and myotonia will be used, all with purpose to evaluate upper limb function.
