Over time, the cohort demonstrated only a modest decline in function as measured by strength measurements,electrophysiologic assessments, and timed functional tasks. There was no association between symptoms of late deterioration and magnitude of decline. Rather, the presence of these symptoms was associated with the magnitude of the residual deficits.展开更多
