Using the Smedley hand dynamometer
Grip Size To size grip, open latch on right side of dynamome-
ter so grip could rotate freely. Rotate grip clockwise for larger
grip and counter-clockwise for smaller grip. As a grip size ref-
erence, measure the distance between grip base and base of
frame. Record this measurement. When appropriate grip size
is reached, close latch and administer grip test. Tests should
not be administered while grip can rotate freely. Grip size
should always be the same for a single individual.
Procedure When administering grip strength tests, face
gauge outward, facing away form patient. Stabalize patient’s
arm and instruct patient to gradually increase effort until max-
imal effort is attained. This might take three seconds or so.
Record reading and reset dial. Repeat test three times, allow-
ing the patient a brief period to rest between each trial and use
the average of the three trial to determine the grip strength.

Smedley hand dynamometer
The Smedley spring-type dynamometer has been used suc-
cessfully for many years to measure grip strength. Adjustable
handle comfortably accommodates any hand size. Unit is cal-
ibrated in both pounds and kilograms. Force inidication point-
er remains at maximal force until reset. To reset, simply rotate
pointer counter-clockwise untul it rests against the zero pin.
Force Range: Measures from zero up to 220 pounds (100
kilograms). Use the child size (110 lb. maximial force reading)
for smaller forces and higher resolution.
Resolution and Precision Measurement gradations are
every five pounds (within black outer ring) and are every 2
kilograms (within white inner ring).
Care: For continued use of the dynamometer for years to
come be sure to take good care of it. Keep unit in protective
carrying case when not in use to prevent water damage and
accidental dropping. Wipe off any water or liquid that might get
on dynamometer to prevent the spring from rusting.
