Characteristics of wrist motion (area, axis, and location) during activities of
daily living (ADL) using electrogoniometry. METHODS:
A sample of 83 normal
volunteers performed the Sollerman hand function test (SHFT) with a flexible
biaxial electrogoniometer applied to their wrists. This technique is accurate and
reliable and has been used before for assessment of wrist circumduction in normal
volunteers. A software package was used to overlay an ellipse of best fit around
the 2-dimensional trace of the electrogoniometer mathematically computing the
area, location, and axis angle of the ellipse. RESULTS: Most ADL could be
completed within 20% of the total area of circumduction (3686 degrees degrees +/-
1575 degrees degrees ) of a normal wrist. An oblique plane in radial extension
and ulnar flexion (dart-throwing motion plane) was used for rotation (-14 degrees
+/- 32 degrees ) and power grip tasks (-29 degrees +/- 25 degrees ) during ADL;
however, precision tasks (4 degrees +/- 28 degrees ), like writing, were
performed more often in the flexion extension plane. In the dominant hand, only 2
power tasks were located in flexion region (cutting play dough [ulnar] and
pouring carton [radial]), precision tasks were located centrally, and rotation
and other power tasks were located in extension region. DISCUSSION: This study
has identified that wrist motion during the ADL requires varying degrees of
movement in oblique planes. Using electrogoniometry, we could visualize the area,
location, and plane of motion during ADL. This could assist future researchers to
compare procedures leading to loss of motion in specific quadrants of wrist
motion and its impact on patient's ability in performing particular ADL. It could
guide hand therapists to specifically focus on retraining the ADL that may be
affected when wrist range of motion is lost after injury. LEVEL OF EVIDENCE:
