Finger flexor muscle test

The deep flexor muscle strength test is a method to check whether the muscle is paralyzed and the degree of paralysis. The main function of the deep flexors of the third and fourth fingers is to flex the third and fourth fingers. When the muscle is paralyzed, the hand is tilted to the radial side, and the wrist cannot be bent; when the paralysis is mild, the fourth and fifth fingers cannot fist.
