Filter by:This study aims to determine if patients with Chronic Obstructive Pulmonary Disease (COPD) exhibit altered muscle properties (specifically changes in tone and stiffness) in both their respiratory muscles and skeletal muscles when compared to healthy individuals. The study will utilize the Myotonometer, a non-invasive device, to assess these properties.
The objective of this research is to evaluate the benefits of an experimental therapy for motor recovery of the arm after a stroke, which includes the application of a functional electrical stimulation therapy coupled to P-300 based Brain-Computer Interface system (BCI-FES). For this purpose, the investigators will compare two groups, the first one will receive only conventional physical and occupational therapy, while the second one will receive conventional therapy together with BCI-FES therapy. The control and experimental group will receive 20 sessions of conventional physical and occupational therapy at a rate of five sessions per week for 4 weeks (control group double dose of conventional therapy), and the experimental group will receive 20 sessions of rehabilitation with the BCI-FES system at a rate of five sessions per week for 4 weeks. Broadly speaking, the BCI is in charge of determining the movement selected by the individual and assist the hand movement while performing functional tasks. The movements included in the sessions will be hand opening, grasping, pinching, pronation and supination, which are combined to facilitate the execution of functional movements that are performed together with the manipulation of daily used utensils. The visual, sensory and motor feedback provided by the BCI-FES system that enables the individual to replicate the afferent-efferent motor circuit, contributes to the activation and recruitment of neural pathways, which is associated with motor recovery. It should be noted that this BCI-FES system has already been tested previously in a study with healthy individuals, and in a non-randomized pilot study that used this therapy for upper limb motor function recovery in chronic post-stroke patients. To evaluate the results, a series of tests will be applied to assess the motor recovery, including the FMA-UE: Fugl-Meyer Assessment Scale of Upper Extremity, ARAT: Action Research Arm Test, MAS: Modified Ashworth Scale, FIM: Functional Independence Measure and MAL: Motor Activity Log. Likewise, resting state functional magnetic resonance imaging studies will be performed to evaluate the degree of functional connectivity between various brain regions of interest related to the planning and execution of movements. This will determine whether the experimental therapy with BCI-FES favors arm and hand recovery in surviving stroke individuals.
The study's purpose is to evaluate whether creatine supplementation can help breast cancer survivors respond quicker to exercise by improving strength, endurance, and body composition. We are seeking to compare information collected from healthy woman of the same age who have never had breast cancer to those participants who have had breast cancer and undergone chemotherapy treatment.
The purpose of this study is to measure the pharmacokinetics (PK), pharmacodynamics (PD), safety, tolerability, and immunogenicity of efgartigimod PH20 SC in pediatric participants with gMG aged 2 to <18 years. The primary goal is to confirm an appropriate dose of efgartigimod PH20 SC for pediatric patients using PK and PD results from this study. Participants will receive injections of efgartigimod PH20 SC and will be monitored for safety until the end of the study. At the end of the follow-up period, eligible participants may roll over to an open-label extension (OLE) study.
This study is a single-center, open-label, single-arm, dose-exploration study to evaluate the safety and preliminary effectiveness of CD19-BCMA CAR-T in the treatment of refractory, generalized myasthenia gravis. The study is a dose escalation trial in adult, refractory, systemic MG patients. The Keyboard method will be used to perform dose escalation to explore the maximum tolerated dose (MTD). A total of 12 MG patients who meet the inclusion criteria are expected to be recruited.
RESET-MG: A Phase 1/2 Open-Label Study to Evaluate the Safety and Efficacy of CABA-201 in Participants with Generalized Myasthenia Gravis
The goal of this quasi-experimental study using a pre and post test design is to learn about the effect of participating in an exercise program with hydraulic exercise equipment on fall risk in the older adult population. The main questions it aims to answer are: - Does the use of hydraulic exercise equipment decrease fall risk in older adults? - Does the use of hydraulic exercise equipment improve function in older adults? Participants will be evaluated pre and post intervention for strength, fall risk using Berg Balance Scale, Tinetti Balance and Gait Assessment, Timed Up and Go, and functional ability using the Lower Extremity Functional Scale. Participants will engage in an exercise program using 5 different pieces of hydraulic exercise equipment (Frei FACTUM® novus II line) 2x/week for for 6 weeks for 30-45 minutes each session. The equipment uses concentric movements only and works agonist and antagonist muscles with each machine (IE: push and pull, both concentric).
Myasthenia is an autoimmune disease causing dysfunction of the neuromuscular junction, resulting in fluctuating and variable muscle weakness. In the initial phase of the disease, 70% of patients present with ocular onset myasthenia (OMG), i.e. weakness limited to the oculomotor muscles. Generalization to skeletal, bulbar and axial muscles occurs in 20-40% of cases, with a higher frequency in the first and second years, respectively 46% and 60% of generalizations. This reflects the maturation of the autoimmune response in the early years of the disease, and represents a therapeutic window of opportunity to modify the course of the disease. Generalization is a critical event, putting the patient at risk of admission to an intensive care unit and necessitating the use of long-term immunosuppressants. There is currently no validated strategy for preventing generalization. On the one hand, a preventive role for corticosteroid therapy in ocular-onset myasthenia has been observed in some studies, but not confirmed by others. These contradictory results may be explained by the bias of retrospective observational studies and the use of different corticosteroid administration regimens. On the other hand, recent data on the use of low-dose Rituximab in the early phase of the disease shows greater efficacy than later use, enabling prolonged remission of the disease with a very good tolerability profile. We propose to compare in a randomized controlled trial the usual practice with a proactive strategy with a standardized corticosteroid regimen immediate at diagnosis. Patients with ocular myasthenia are usually treated symptomatically with acetylcholinesterase inhibitors. The introduction of corticosteroids is delayed and limited to patients with persistent disabling diplopia or ptosis with occlusion. When corticosteroids are tapered off, ocular symptoms may recur. This level of corticosteroid dependence observed in patients treated for ocular myasthenia has not been specifically studied. In order to reduce the levels of corticosteroids administered and avoid recurrence of ocular symptoms and their delayed generalization, it is usually proposed to introduce another immunosuppressant. The aim of this study is to evaluate the efficacy of a standardized proactive prevention strategy on the generalization of ocular onset myasthenias during the first 2 years. It will combine immediate treatment with corticosteroids at the time of diagnosis, with the addition of rituximab in the event of recurrence of ocular symptoms as corticosteroids are tapered off.
Pelvic floor muscle weakness is one of the most important causes of incontinence. There are many studies supporting that pelvic floor muscle training prevents incontinence and reduces symptom severity, and with A level of evidence, it is among the first in the conservative treatment of incontinence. Functional status and balance problems are common in elderly people with incontinence, and it is known that functional type incontinence is common. Elderly people with incontinence most often fall while trying to get to the toilet. Balance exercises are recommended for falls and balance problems. The aim of this study is to examine the effects of pelvic floor muscle training and balance exercises on ankle muscle function, joint range of motion and balance in individuals aged 65 and over with urinary incontinence.
Background: The aim of this study was to compare the knee and ankle muscle architecture and plantar pressure distribution differences in knee osteoarthritis (OA) women with healthy women. Methods: Fifty women with knee OA (Mean age=52.11±4.96 years, mean BMI=30.94±4.23 kg/m2) and fifty healthy women (Mean age= 50.93±3.78 years, mean BMI=29.06±4.82 kg/m2) were included in the study. Ultrasonography was used to evaluate Rectus Femoris (RF), Vastus Medialis (VM), Vastus Lateralis (VL), Peroneus Longus (PL), Tibialis Anterior (TA), and Medial Gastrocnemius (MG) muscle thickness, pennation angle, fascicle length, and fat thickness. The plantar pressure distribution was evaluated using the Digital Biometry Scanning System and software (DIASU, Italy).
