Magnetic Resonance and Optical Imaging of Dystrophic and Damaged Muscle

This arm will only include subjects that have a confirmed diagnosis of Duchenne Muscular Dystrophy. Subjects in this arm will not undergo any exercising, and will only be imaged by Optical and Magnetic Resonance Imaging and Spectroscopy techniques at a single time point.

This arm will contain subjects that are not affected by Duchenne Muscular Dystrophy. These subjects will undergo concentric exercising of one forearm, and eccentric exercising of the contralateral forearm. Two days following the exercising, subjects will undergo Optical Imaging and Magnetic Resonance Imaging and Spectroscopy.
