Hydraulic Hand Dynamometer

The hand dynamometer can be used to measure grip strength. It is calibrated in pounds and kilograms of force.

The grip handle is adjustable to accommodate various hand sizes. Always use the same grip setting and dynamometer when evaluating a specific subject for hand trauma or disease.

Set the handle to the desired position. Have the subject hold the dynamometer in a comfortable position. The shoulder should be adducted and neutrally rotated, the elbow flexed to 90 degrees, and the forearm and wrist should be in a neutral position. Have the subject squeeze the handle using his/her maximum effort.

The red maximum pointer will remain at the subject’s maximum reading until it is reset. The red maximum pointer must be reset before each grip test. Rotate the small knurled knob on top of the dial indicator in a counterclockwise direction until it rests against the black pointer at the zero marking. Each grip test should be repeated three times and the average result should be used.

Grip strength varies depending upon the size of the object being grasped. The adjustable handle allows for quantification of grip strength for different sized objects.

To determine whether a subject is exerting maximum effort use the following protocol:
• Take readings with adjustable handle in all five positions
• Test the normal hand and then the injured hand
• Repeat the test after five minutes

If maximum effort was exerted there should be approximately a 10% variation in the two sets of test results.

Mechanical Pinch Gauge
The finger pinch gauge can be used to measure pinch strength. It is calibrated in pounds and kilograms of force.
Apply pinch force at the pinch groove while holding the pinch gauge between your thumb and finger(s).

When force is applied farther toward the tip the reading will be slightly higher. When force is applied farther toward the rear the reading will be slightly lower.

The gauge must be “zeroed” before each pinch test. Grasp the knurled ring of the dial indicator and rotate it until the zero on the dial indicator is directly under the black pointer.

The red maximum pointer must be reset before each pinch test. Rotate the small knurled knob on top of the dial indicator in a counterclockwise direction until it rests against the black pointer at the zero marking. The red maximum pointer will remain at the subject’s maximum reading until it is reset.

Finger Goniometer
The finger goniometer can be used to measure active or passive joint range of motion (ROM). It measures joint flexion and hyper-extension. It is calibrated in degrees.

Align the fulcrum of the goniometer with the anatomical fulcrum of the joint being measured. Place the flat arm of goniometer that is attached to the dial indicator on the center of the limb (or extremity) to me measured. Hold both arms of the goniometer and move the joint through its entire range-of-motion (this can be done actively by the subject or passively by the examiner). The range of motion can be read directly from the dial indicator.

3-Point Aesthesiometer

The aesthesiometer is a sensory device that measures a subject’s perception of the cutaneous two-point threshold. The third point makes it possible to alternate between single-and double-point stimulation without changing the distance setting. The device is very lightweight so as not to influence the touch and/or pain threshold. The tips are plastic to minimize the influence of temperature sensation.

Blindfold the subject or have the subject close his/her eyes. Set the two points close together (minimal distance reading). Lightly touch both points simultaneously to the subject’s skin. Ask the subject whether he/she feels one or two points. If the answer is one point then reset the two points farther apart and repeat the test until the subject reports that he/she feels two points. Read the two points’ cutaneous threshold directly from the calibrated scale on aesthesiometer body.

During the trial, as a check, one point only should be used to touch the skin on some trials. This can be done by using the convenient third point or by separating the two points so that only one point can be used. Different areas of the skin have markedly different two-point thresholds. It is interesting to note that there is an increase in two-point cutaneous sensitivity brought about by practice and a transfer effect from one symmetrical skin area to another after practice on the first area.

Finger circumference gauge

The finger circumference gauge can be used to measure finger diameter and/or swelling associated with edema. It is calibrated in inches and centimeters.

Wrap the webbing around the finger to be evaluated. Thread the webbing through the eyelet on the ruler. Pull the webbing tough and read the finger circumference measurement directly from the ruler.

Pinwheel

Use to elicit a subject’s cutaneous sensory and/or pain perception. The test elicits a gross yes/no (on/off) response. There is no specific calibration unit.

Move the pinwheel over the skin area to be tested. Ask the subject whether he/she feels one or two points. If subject responds negatively the test may be repeated using more pressure on the pinwheel.

Functional finger motion gauge

Measures composite finger flexion and thumb-finger opposition. It is calibrated in centimeters.

Composite finger flexion: Place the flat end of the plastic gauge on the subject’’s palmer crease and have the subject flex his/her fingers. Read the composite flexion of each finger directly from the gauge (distance from the palmer crease to the fingertip of the maximally flexed fingers).

Thumb and finger opposition: Have the subject grasp the smallest step possible between the thumb and finger. Repeat for each finger (index, middle, ring and pink).
