About
This trial is studying Electrical Impedance Myography (EIM) for measuring muscle health. The trial is studying people with Amyotrophic Lateral Sclerosis (ALS), other neuromuscular diseases, and healthy volunteers to see if the EIM device can measure disease in muscle tissue.
Full description
This is a multicenter, 9-month study evaluating the effectiveness of electrical impedance myography (EIM) as a diagnostic and disease-tracking tool. In addition, the following will be studied:

ALS Disease Mimics Inclusion Criteria:
a. Pure Lower Motor Neuron Disease (LMND) mimics: i. Multi-focal motor neuropathy ii. Autoimmune motor neuropathy iii. Cervical or lumbosacral radiculopathies with weakness involving more than one extremity or more than a single myotome if restricted to one extremity.
iv. Multiple peripheral mononeuropathies with clinical weakness v. Charcot-Marie-Tooth Disease vi. Any condition that produces generalized or localized weakness without concomitant sensory symptoms, including myasthenia gravis or myopathy, that the evaluating physician deems mimics ALS.
