The Baseline
®
Finger Flexion Gauge is a tool used to
measure finger flexion and/or opposition. This device uses
the measurement method recommended by the American
College of Orthopedic Surgeons*
DIRECTIONS FOR USE
To Measure Composite Finger Flexion:
Measure the distance from the fingertip to the:
a. distal palmar crease (for middle and distal joints)
b. proximal palmar crease (for distal, middle and proximal joints)
Place flat end of Finger Flexion Gauge on the palmar crease
(distal or proximal) and flex fingers to maximum. Record the
distance; indicate starting point and whether measurement
to mid-point of pad or nail edge.
Composite Flexion Example (see Figure 1)
Palmar crease to little finger: 3½ cm
Palmar crease to ring finger: 4 cm
Palmar crease to middle finger: 4½ cm
Palmar crease to index finger: 4½ cm
Opposition of the Thumb and Fingers:
To measure the limitation of opposition find the smallest
pinch distance between the thumb tip and fingertip.
Opposition Example (see Figure 2)
Smallest possible pinch distance is 3 cm.
*For a description of composite motion of flexion and opposition of the
thumb and fingers, see: "Joint Motion, Method of Measuring and Record-
ing", published by the American Academy of Orthopedic Surgeons, 1965.
