Brief summary
There is a great need for the development of sensitive outcomes that allow experimental drugs to be tested in human subjects more efficiently. If we could more precisely measure whether an experimental drug slows the progression of ALS or other neuromuscular diseases, this would allow more drugs to be tested quicker and at less expense. We have developed a new device that accurately measures isometric strength called: Accurate Test of Limb Isometric Strength (ATLIS). This device was designed to be portable, quick, and easy to use, while generating accurate and reliable, interval level data. This study will enable us to test the reliability and validity of ATLIS.
