CBS Boston’s Liam Martin visits with Dianne Vitkus, a surgical physical assistant who was paralyzed in a fall last summer and recently received a Freedom Chair, an off-roading wheelchair developed by GRIT, an MIT startup. “The technology is simple. There’s a lever on each side that connects to a bike chain and allows Dianne to propel the chair,” says Martin. “It also has heavy-duty tires and a front wheel for stability.”
