Because researchers have made such striking progress in developing drugs to treat neuromuscular diseases, Scott Delp, Ph.D., was surprised to learn that scientists conducting clinical trials were still relying on a decidedly low-tech tool to track whether those treatments were working: a stopwatch.
In a study published in NEJM AI, Delp, a professor of bioengineering, and his collaborators showed that a smartphone could do the job as well or better. With two smartphone cameras and a free app, they were able to replicate results from standard movement tests for two neuromuscular diseases and capture more detail about patients’ physical abilities.
“Our goal was to bring the world’s most sophisticated biomechanical modeling and computer vision to bear in order to match...
