Testing a new muscle scan device to track ALS progression

This trial is testing whether a device called the Myolex mScan—which uses a painless electrical scan to measure muscle health—can effectively track how ALS progresses in individual patients. Currently, doctors rely on a rating scale that changes very slowly and may miss real improvements from new treatments. This study aims to see if the mScan can detect changes in muscle function more accurately and sensitively than existing methods.

ALS is a serious disease, but new treatments are being developed that can slow its progression. To know whether these treatments actually work, doctors need better ways to measure disease changes quickly and objectively. This trial exists because the current standard measurement tool is slow to show change and makes it hard to tell if new treatments are really helping.
