Researchers claim success treating genetic muscle disorder

Scientists at the University of Pittsburgh on Wednesday said an experimental device helped three people with spinal muscular atrophy walk and stand more easily. In the research study, implants delivered small shocks to the spinal cords of the participants. Researchers said devices could help temporarily restore muscle function. Spinal muscular atrophy is a genetic disorder that gradually breaks down nerve cells in the spinal cord that control muscle movement.

Though the device did not restore the patients’ normal movement, a few hours of stimulation per week did increase their strength and muscle function, according to the written study. All three patients were able to walk farther and experienced less fatigue with physical activities, though the benefits did not last long after researchers removed the implant.

What else could the device be used for? Scientists were already testing the device for paralysis and muscle weakness caused by stroke. Two patients who participated in a pilot study experienced improved hand and arm control within four weeks. As with the patients with atrophy, the benefits ended after researchers removed the device.
