Intrinsic muscle strength measurement of the little finger with RIHM dynamometer
The patients hand is supinated while the second, third and fourth fingers are held by the
examiners hand. The patients little finger is placed in maximum abducted position with the MP
joint in slight flexion. The patient is told to keep the finger in that position while the sling of the
dynamometer is applied at the PIP joint of the little finger. The pull is always perpendicular to the
axis of the little finger; parallel to the palm of the hand.
