Why is it hypothesized that the ECU is active during wrist flexion?
What will be an ideal response?
ANS:
The hypothesis that accounts for the unexpected activity of the ECU during wrist flexion is that the ligamentous structure of the wrist is more plentiful on the radial side, leaving the ulnar side less stable. This decreased stability on the ulnar side may require the addition of the active compressive force of the ECU.
