Open the original- What it measures
- Ulnar deviation means bending the wrist toward the little-finger side. The configurations differed in opening angle and separation, and produced similar ulnar deviation to each other.
- What it does not show
- Measures wrist angle only. It does not show that split keyboards prevent symptoms.
