The Claim

In humans following complete ulnar or above-elbow median nerve sections, motor unit size (twitch amplitude) demonstrates no significant correlation with recruitment threshold, which indicates an absence of orderly recruitment.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

When certain nerves in the arm are completely cut, the way muscles respond doesn't follow the usual pattern where smaller movements happen before bigger ones.

What the research says

1 study

  1. Study: Patterns of reinnervation and motor unit recruitment in human hand muscles after complete ulnar and median nerve section and resuture.

    The study looked at the same nerve injuries as the claim and found exactly what the claim says: no clear pattern in how muscles are recruited after these injuries, because the nerves grow back in a messy way.
