Gentamicin Treatment of Muscular Dystrophy
Becker Muscular DystrophyDuchenne Muscular DystrophyThis study will evaluate the antibiotic gentamicin for treating patients with muscular dystrophy caused by a specific genetic abnormality known as a nonsense mutation. In studies of mice with this type of muscular dystrophy, gentamicin treatment produced positive changes in muscle tissue. Patients with Duchenne or Becker muscular dystrophy caused by nonsense mutations by may be eligible for this 2-week study. Before starting treatment, patients will have evaluations of muscle strength and general well being. Two muscle tissue samples will be taken by needle biopsy, under local anesthetic and sedation. Because of potential risks of hearing loss and kidney toxicity associated with gentamicin, patients will also have a hearing test and blood and urine tests for kidney function before starting treatment. (Currently, gentamicin is commonly prescribed for serious infections of the lungs, heart, and digestive and urinary tracts; adverse effects of hearing loss and kidney toxicity can occur with excessively high drug doses.) Patients will be hospitalized during drug treatment. Gentamicin will be given intravenously (through a vein) once a day for 14 days. Blood samples will be collected daily to monitor drug levels and determine dosage adjustments, if necessary. Urine samples will be collected to assess kidney function. Hearing tests will be done on days 7 and 10. On the last day of the study, hearing, kidney function, and muscle strength will be tested and the results compared with pre-treatment levels. Blood and muscle samples will also be taken again for pre-treatment comparison. Hearing, blood, urine, and muscle strength tests will be repeated one month after treatment ends for comparison with previous results.
Phase III Randomized, Double-Blind Study of Prednisone for Duchenne Muscular Dystrophy
Duchenne Muscular DystrophyOBJECTIVES: I. Characterize the effect of prednisone on muscle protein metabolism in patients with Duchenne muscular dystrophy. II. Determine whether prednisone changes levels of insulin-like growth factor 1, growth hormone, and insulin. III. Characterize the effect of prednisone on muscle morphometry and muscle localization of utrophin. IV. Compare the prednisone response in patients with Duchenne muscular dystrophy to that seen in normal individuals and in patients with facioscapulohumeral dystrophy.

Investigation of the Validity and Reliability of the Kinesthetic and Visual Imagery Questionnaire...
Duchenne Muscular DystrophyMotor imagery (MI) can be defined as a dynamic process in which the person is mentally stimulated without performing the given motor movement. Studies of imagery; demonstrated that it alters a person's ability to learn, performance skills, and important cognitive skills (self-efficacy, self-confidence, effort, motivation). In recent years, it has been shown that motor imagery techniques are used for therapeutic purposes as a current neurorehabilitation approach and that imagery can have positive effects on improving motor activity and functions. However, it has been reported that the biggest difficulty in the use of imagery techniques is the inability to determine to what extent the individual can perform mental representation of movements. For this reason, it is thought that it is necessary to evaluate the motor imagery ability first in order to identify the patients who are suitable for motor imagery training. The Kinesthetic and Visual Imagery Questionnaire (KVIQ) is a motor imagery questionnaire developed for individuals with limited mobility for different reasons. The questionnaire assesses both the visual and kinesthetic dimensions of motor imagery. of the KVIQ; It has also been shown in the literature that it is a valid and reliable questionnaire that enables the appropriate evaluation of motor imagery in different neurological disease groups such as Multiple Sclerosis, Parkinson's disease, and stroke. However, the literature When examined, no evidence was found about the motor imagery ability of individuals with Duchenne muscular dystrophy (DMD). It is foreseen that KVIQ will be especially suitable for patients with DMD of different functional levels, since all its items have been developed to be applied to people with limited physical mobility or physically disabled people in a sitting position. Therefore, in this study, it is aimed to investigate the validity and reliability of the Kinesthetic and Visual Imagery Questionnaire for patients with DMD.
Bicycle Ergometer Training in Duchenne Muscular Dystrophy
Duchenne Muscular DystrophyThe progressive muscle weakness and contractures of the patients adversely affect their gait and balance. It is known that the disorder of the patients' balance and gait affects their functional capacity. The aim of this study is to examine the effects of bicycle ergometer training on gait and balance in children with Duchenne Muscular Dystrophy. Twenty-four children with DMD included in the study will be divided into two groups as home program and home program+bicycle ergometer training with block randomization method. Home program including stretching, respiratory, range of motion, posture and mild resistance exercise with body weight will be asked to apply 3-5 days a week for 12 weeks, aerobic training will be performed 3 days a week for 12 weeks at 60% of their maximum hearth rate with 40 minutes total duration consisting of 5 min warm up and 5 min cool down period. Gait and balance were evaluated with GAITrite and Bertec Balance Check Screener, successively. Assessments will be applied at pre-training and after 12 weeks of training.
Effects of Low-level Mechanical Vibration on Bone Density in Ambulant Children Affected by Duchenne...
OsteoporosisDuchenne Muscular DystrophyDuchenne muscular dystrophy (DMD) is a X-linked recessive disorder due to a mutation of the dystrophin gene (Xp21). Dystrophin is a sarcolemmal protein of skeletal and cardiac muscle, and its absence causes progressive muscle degeneration and substitution with fat and connective tissue. The progressive muscle degeneration leads to loss of autonomous walking before the age of 15 years and death for cardiac and/or respiratory failure. There are no specific treatment for DMD, and the standard of care is now based on long-term corticosteroid (CS) use. The studies on bone mass in DMD are very few, but they agree in reporting the presence of a reduced bone mass and an increased rate of fractures probably due to long-term steroid therapy and disuse-osteopenia. The aim of this study, involving 20 ambulant DMD boys (age 7-10 years) has been the evaluation of the effects of low-level mechanical vibrations on bone in a group of ambulant DMD children for 1 year, with RDA-adjusted dietary calcium intake and 25OH vitamin D supplementation.
