Scientists have discovered that muscle cells affected by muscular dystrophy contain high levels of an enzyme that impairs muscle repair. This finding provides a new target for potential drug treatments for the disease, which currently has no cure. Muscular dystrophy (MD) is an inherited genetic condition that gradually causes a weakening of muscles.
Five men with complete motor paralysis were able to voluntarily generate step-like movements thanks to a new strategy that non-invasively delivers electrical stimulation to their spinal cords. The strategy, called transcutaneous stimulation, delivers electrical current to the spinal cord by way of electrodes strategically placed on the skin of the lower back.
