eimThis is a longitudinal study designed to assess whether electrical impedance myography (EIM) is a useful measure of disease progression in ALS. EIM is a painless and non-invasive technique that can be used to quantify the biophysical properties of muscle. The study will involve several visits to a study center for serial evaluations. If successful, this study will demonstrate that the use of EIM as an outcome measure would make it possible to complete clinical trials in a shorter period of time and require participation of a small number of people.
