Active clinical trials for "Multiple Sclerosis"

Activation is the amount of voluntary recruitment of a muscle during voluntary contraction. Full activation implies the recruitment of all muscle fibres at their tetanic frequency. In healthy subjects, and even in sports performances, full activation may be rarely achieved despite a subjectively maximal effort. Highly decreased activation has been observed in patients affected by various orthopaedic and neurological disorders. In these subjects, paresis may be caused or aggravated by primitive impairments of the central nervous system and/or, by stimuli arising from peripheral damaged tissues that inhibit the corticospinal or the intraspinal recruitment of motoneurones ("arthrogenous muscle weakness"). There are numerous investigations in the literature on activation measured during isometric contractions, while they are substantially missing as far as isokinetic concentric contractions are concerned. There are reasons to suppose that, contrary to what has been demonstrated for healthy subjects, in patients with various motor impairments the activation is diminished the more, the higher is the joint rotation speed. The present study aims to investigate the amount of activation of the quadriceps femoris during subjectively maximal isometric contractions at 40° knee flexion (0°=complete extension) and isokinetic concentric contractions at an angular velocity of 100°/s in patients with various orthopaedic and neurologic conditions. Activation will be measured on an isokinetic dynamometer, through the "interpolated twitch technique". This consists of stimulating a representative sample of the muscle belly through an electric shock. If the shock does not generate an extra force during contraction, all muscle fibres belonging to the sample reached by the electric shock can be claimed to be recruited at their tetanic frequency. Otherwise, following the stimulus, a twitch can be observed revealing submaximal voluntary recruitment of the muscle.

This nested project of the Swiss Multiple Sclerosis Cohort (SMSC) is to assess the severity of COVID-19 and the magnitude of antibody response after infection with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in patients already treated or not with various immunotherapies for multiple sclerosis followed in the framework of the SMSC.

Trunk control disorders are frequently encountered in individuals with MS. Trunk control is very important for safe and quality movement. Impairment of trunk control reduces the level of independence of individuals during activities of daily living. For this reason, it is extremely important to evaluate the trunk in the examination and treatment of individuals. When the literature was examined, it was seen that studies examining trunk control were insufficient. Therefore, our study was planned to investigate the relationship between disability level and trunk control in individuals with MS.

Intravoxel incoherent motion (IVIM) is technique based on diffusion-weighted imaging (DWI). In this study, the investigators evaluate the use of IVIM in patients with Multiple Sclerosis.

This is a non-interventional primary use of data study utilizing de-identified patient-level onboarding and adherence data managed through the MSGo patient support service platform and includes a sub-study to explore the impact of ofatumumab on relevant patient reported outcomes (PROs) with respect to clinical outcomes.

ActiSEP is a multicentric academic study. Ambulant patients with multiple sclerosis may be included on a voluntary basis. The investigators plan to include a group of approximately 80 patients with MS, fulfilling the McDonald's 2017 criteria, of whom 40 of them show a progressive course according to the Lublin classification. The investigators have planned two visits (at baseline and 1 year later). On both visits, participants will perform few tests (timed 25-Foot Walk (T25-FW), 9-Hole Peg Test (9-HPG), 6-minutes walk test (6MWT), Berg balance scale) and will answer to some questionaires (Godin Leisure Time Exercice Questionnaire, multiple sclerosis walking scale, modified fatigue impact scale, Hospital Anxiety and Depression Scale) After each visit, participants will wear Actimyo for three months in daily living.

The primary objective of this project is to track changes over time in balance control parameters measured during stance and gait for different groups of multiple sclerosis (MS) patients. Our primary goal is to determine whether these changes in balance control over time predict transitions in MS progression to a more disease affected state, and are different from changes over time for patients with balance deficits due to vestibular sensory disorders. A part of this goal is also to determine whether these changes in balance control are correlated with changes in patients' self-reported deficits and are similar to those changes in balance control of patients with peripheral vestibular loss. The secondary objective is to determine for multiple sclerosis (MS) patients the relationship of their balance parameters to different gait speeds, in order to advise them on, and promote via feedback, safe walking speeds. Fulfilling the first of our objectives would lead to better tracking of MS disease changes over time, earlier quantification of onset of symptoms suggesting a worsening of disease status, and, we assume, greater patient satisfaction knowing that quantification of symptoms fits subjective feelings of balance deficits during stance and gait. Achieving the second objective would lead to improved balance during gait. We aim to carry out these objectives using equipment (SwayStar) which we have proven is sensitive to MS induced balance deficits {2}, but costs far less to operate and maintain than previously used quantification tools. We aim to investigate the balance deficits during gait in different MS patient groups using a multimodal approach with a SwayStar system (analysis of balance during stance and gait in terms of trunk-pelvis movements near the centre of mass) and patient questionnaires.

The visual prognosis of optic neuritis not related to multiple sclerosis is unknown, both in terms of functional recovery and evolution. This prospective cohort study aim to assess the ophthalmological evolution of patients presenting an episode of optic neuritis (NO) not related to a multiple sclerosis or to a clinically isolated syndrome.

The purpose of the study is to explore association patterns between digital outcome assessments from Konectom and MRI measures of brain tissue damage.

The purpose of this study was to investigate the factors that influence the progression of patients with clinically isolated spinal cord syndrome to multiple sclerosis.
