The Baseline 12-0112 Digital Hand Evaluation Set with portable carrying case contains all instruments necessary to evaluate the strength and range-of-motion of the hand and fingers. The Baseline Hand Evaluation Set includes hydraulic hand dynamometer, hydraulic pinch gauge, and a six inch stainless steel goniometer. The Baseline 12-0112 Hand Evaluation Set provides user convenience, reliability and measurement repeatability. Baseline dynamometers and pinch gauges have been manufactured in the USA since 1978.

The Hydraulic Hand Dynamometer tests up to 300 lbs (135 kg). Baseline digital hand dynamometers use a hydraulic system with the added advantage of an LCD display. The digital hand dynamometer includes an electronic zero calibration system, 2 AAA batteries, a low battery light, and an automatic shut off. Additional features include a push button console with a button to zero, last maximum reading stored in memory, a maximum button to display the highest reading, and a lb/kg toggle. Baseline hydraulic hand dynamometers give accurate grip strength readings without the subject being able to feel the handle move. The dynamometer features an internationally accepted design engineered to be durable, so it will last for years and years. The 2006 model uses new technology to create stronger parts. Five position adjustable handle and body design yield results that are consistent with published Baseline and Jamar studies.

The Hydraulic Pinch Gauge tests up to 100 lbs (45 kg). Baseline pinch gauges use the hydraulic system of the hand dynamometer with the added advantage of an easy-to-read LCD display. Additional features include an electronic zero calibration system, 2 AAA batteries, a low battery light, and an automatic shut off. The pinch gauge push button console includes a button to zero the last maximum reading stored in memory, a maximum button to display the highest reading since the last press of the maximum clear button, and lb/kg toggle button to change the measurement reading. The therapist can support the pinch gauge during testing. This yields a more accurate result for all pinch tests including tip, key and palmer. Results are consistent with published Baseline and Jamar studies.

Deluxe, 6 inch stainless steel finger goniometers measure range-of-motion of finger joints (metacarpophalangeal and interphalangeal) and other small joints including toes. The head has two opposing 180 degree scales marked in 5 degree increment. Goniometers feature a linear scale in inches and centimeters on the arm. The deluxe model goniometer has a larger head for more accurate readings.

To use the Dynamometer, 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 with the elbow flexed to 90 degrees. The forearm and wrist should be in a neutral position. Have the subject squeeze the handle using his or 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. Then, 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. Take readings with adjustable handle in all five positions. Test the normal hand and then the injured hand. Repeat the test after five minutes.

To use the Finger Goniometer, first align the fulcrum of the goniometer with the anatomical fulcrum of the joint being measured. Then, place the flat arm of the goniometer that is attachd to the dial indicator on the center of the limb or extremity to be 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.
