- What it is
- A case series from an electrodiagnostic laboratory that tested computer keyboard operators referred between 1995 and 1999 for suspected nerve problems in the arms. The authors measured how many had focal ulnar neuropathy at the elbow, the nerve compression on the inside of the elbow.
- How much weight it carries
- Peer-reviewed, but a case series of referred patients rather than a random sample of typists, so the 105 of 148 figure cannot be read as the share of all keyboard users affected. It also does not measure how much or how long people typed.
Facts taken from this source
- In a 2011 case series of 148 computer keyboard operators referred for nerve testing between 1995 and 1999, 105 had focal ulnar neuropathy at the elbow.
