@jchet I have lost my link to a recent article, but the gist of it was that one of the biggest limitations in clinical research right now is the lacking of willing participants in clinical trials.
For many medical issues, the funding is there, the research is ongoing, but trials struggle to enroll enough participants. One study on bronchiectasis, an uncommon lung disease was only able to recruit fewer than 50% of their patient goal.

Here is how to find neuropathy clinical studies you may be able to participate in to advance the science:
