Active clinical trials for "Muscular Dystrophy, Duchenne"

Background: - Children with Duchenne/Becker Muscular Dystrophy (DBMD) slowly lose muscle function. They usually die at a young age. Some mothers adapt to the demands of caring for a child with this disease better than others. Studies show that a person s hope may positively affect how they cope and adapt. Researchers want to find out more about this. They want to develop ways to improve caregivers overall wellness. Objective: - To study the relationships between uncertainty, hope, and coping ability in mothers of children with DBMD. Eligibility: - Women in the United States 18 years and older. They must be biological mothers of a living child with DBMD and be able to answer a survey in English. Design: This study is part of a larger study that examines the well-being of mothers with sons who have DBMD. Participants will take a questionnaire. The questionnaire can be done on paper or on a computer. It will take 30 45 minutes to complete. The questionnaire will include basic demographic questions about the participant and the child. There will also be questions about how the participant copes with the stress and uncertainty of DBMD. For most of the questions, participants will rate their feelings on a scale. There will also be four open-ended questions.

"Observational study of clinical outcomes for testosterone treatment of pubertal delay in Duchenne Muscular Dystrophy" is a single centre observational study that aims to follow the progress of 20 adolescents with Duchenne Muscular Dystrophy (DMD) and delayed puberty who are treated by the Newcastle muscle team, as they are treated with testosterone to induce puberty. The participants will all be treated with the standard stepwise regimen of testosterone injections every 4 weeks and data will be collected to help determine the effectiveness and tolerability of the current treatment regimen. The investigators will use the data to explore the effect of testosterone on pubertal development, growth, muscle strength and function, bone mineral density and body composition and characterise any side effects. Semi-structured interviews will also be carried out to learn the boys' views on the tolerability of the regimen. The study will last up to a maximum of 27 months in total for each participant, but may be less if they are happy with pubertal development before this time. It is important to do this study because from the investigator's limited experience in this group, testosterone treatment seems to be well liked and tolerated but the best treatment regimen to use remains unknown and there is no current consensus. It is not currently part of the standard of care in DMD but it would be important to include it if this study can show that it is an effective treatment for pubertal delay.

This is a pilot clinical trial to assess the ability of a new ultrasound-based imaging method, Double-Push Acoustic Radiation Force (DP ARF) ultrasound, to monitor the progression of Duchenne muscular dystrophy. The hypothesis being tested is that DP ARF ultrasound delineates changes in muscle composition and function in individual dystrophic muscles, from early through late stages of disease development, that correlate to time to loss of ambulation in patient volunteers.

The investigator investigated the effect of lower limb flexibility on functional performance of children with Duchenne Muscular Dystrophy.

The aim of this study, determining the factors affecting the hand functions of children with Duchenne Muscular Dystrophy who have lost their independent ambulatory ability and determining the effects on the overall upper extremity performance and quality of life of the determined factors.

This study examine whether an evidence-based individual user-preferred exercise program will increase the physical activity level in boys with Duchenne muscular Dystrophy (DMD).

This research study wants to learn more about Duchenne Muscular Dystrophy (DMD) and exercise. Today it is unknown how exercising impacts boys with DMD. The investigators believe that increasing activity and aerobic exercise may help with heart, lung, and muscle function. The investigators are hoping to compare physical strength and blood samples of boys with DMD to see if there are any differences between kids who exercised more as a child versus those who didn't.

This is a multicenter prospective non-drug screening study. The working period is 12 months. There is no research product to be followed or used in the study. Demographic data, medical and family histories of the patients included in the study will be collected at the first admission. The following laboratory values of the patients will be collected: Alanine Transaminase (ALT) Aspartate Transaminase (AST) Gamma Glutamyl Transferase (GGT) Creatine Phosphokinase (CPK) In addition, physical examination information and Abdominal USG and Liver Biopsy Results, if any, will be collected. Following the above scans, enzyme analysis for late-onset Pompe disease in boys and girls and adolescents with high CPK levels and molecular genetic tests for Duchenne muscular dystrophy in boys and adolescents with high CPK levels will be performed.

This study was planned to investigate the parental influence on physical activity (PA) level and participation in ambulatory children with Duchenne muscular dystrophy (DMD). For this purpose, 30 children with DMD between the ages of 8-18, who were between Levels 1-4 according to the Brooke Lower Extremity Functional Classification (BLEFC), were included in the study. The demographic information of the participants and their detailed information about the disease were recorded. Parents' PA level was assessed via International Physical Activity Questionnaire-Short Form (IPAQ-SF); Children's PA level was assessed via Physical Activity Questionnaire for Children (PAQ-C) and pedometer, participation was assessed via Pediatric Outcomes Data Collection Instrument (PODCI), and parental influence was assessed via Children's Physical Activity Correlates (CPAC). Additionally, children's PA interest was assessed via Children's Attraction to Physical Activity (CAPA). SPSS 25 program was used in the statistical analysis of the evaluation results. The mean age of the individuals included in the study was found to be 8,70±0,84. Parental influence evaluations, positive and weak-moderate correlations were determined between CPAC Questionnaire "Parental Influence" sub-dimension with PAQ-C (r=0,582), CAPA (0,432) and PODCI (r=0,372) (p<0,05). A positive, moderate correlation was found between the PA levels of mothers obtained from IPAQ-SF and PAQ-C (p<0,01). The results of the study show that the parents, especially the mother who is the primary caregiver, can be an important factor to improve the PA levels, increase their attraction to PA and participation in children with DMD.

Background: - Duchenne muscular dystrophy (DMD) is a disease in which the muscles are unable to make the protein dystrophin. Without this protein, the muscles become gradually weaker. A new medicine called GSK2402968 is being tested to see if it can help prevent or slow down this loss of muscle strength. In this study, boys with DMD and healthy volunteers will have different types of imaging studies to see which ones provide the best images of the muscles. This information will help researchers use these imaging techniques to test the safety and effectiveness of GSK2402968 and other agents. Objectives: - To test magnetic resonance imaging and ultrasound techniques that can detect changes in muscles of boys with DMD. Eligibility: Boys who have DMD and are in the GSK2402968 drug test study. Healthy boys of the same age as the above study participants. Design: Participants will be screened with a medical history and physical exam. Healthy volunteers will have one 2-hour visit with three tests. Magnetic resonance imaging (MRI) scans of the skeletal muscles and heart and diaphragm muscles will be carried out. Muscle ultrasound imaging of leg and arm muscles will also be done. Participants should not perform heavy physical activity like school sports or long walks during the week before the visit. Participants in the GSK2402968 study will have the same series of tests as the healthy volunteers. The tests will be given during the study screening phase. They will be repeated after 3 months and 6 months of receiving the study agent (GSK2402968 or placebo) and at 6 months after stopping the GSK study.
