Our digital goniometers are simple and easy to use! Here are some quick instuctions to get you started:
ON/OFF: Press this button to turn on the goniometer. Auto shut-off will occur after 5 minutes of non-use.
ZERO: Press this button at any desired angle to set a new relative zero.
HOLD: Press the HOLD/Rev button to save a measurement. “H” will appear in the upper left corner of the display to indicate that the hold feature is on. Return to normal mode by pressing HOLD/Rev again.
Reverse Display: Press the HOLD/Rev button down for 3 seconds to flip the digital display 180 degrees for easy reading when display is inverted.
The Evolution of Digital Goniometers
In the Physical Therapy clinic, the traditional goniometer is the primary instrument for measuring joint mobility in body. During therapy, objective and accurate measures of joint range of motion are essential in identifying deficits, establishing therapy programs and tracking progress. Traditional goniometers come in many styles and sizes to accommodate various joints. Finger, hip and cervical joint measurements all require different approaches and instruments. Dual-arm goniometers are readily available, inexpensive and can accommodate the widest range of joints in the body. Dual-arm analog goniometers are produced in either plastic or metal and have a rotating protractor fulcrum graduated in one degree increments. For most clinicians, the plastic versions are preferred as they have clear, see-through arms making them easier to align the axis (hinge) with joint fulcrums and stationary and movable blades with bony landmarks.
Digital goniometers are also available, are generally more compact and offer increased accuracy with readouts down to 0.1 degrees. Earlier digital versions were used primarily during research and Functional Capacity Evaluations (FCE), but were cost prohibitive. In recent years, less costly but still highly accurate digital instruments have become available. Fully digital versions such as the Halo, Medigauge and Jamar are used in therapy clinics worldwide. These models can obtain measurements quicker, are accurate down to 0.1 degrees, have the ability to store measurements and can determine relative ranges without calculations. The digital goniometer allows for self-measurement, increasing the applicable uses of the goniometer. The digital goniometer's benefits outweigh the current standard of goniometers, showing in the years to come digital goniometers will become more prevalent in the physical therapy industry.
