The Gollehon Extendable Goniometer is an innovative tool in the assessment of range of motion. Its arms can extend to 22.25″ to measure large joints and retract to 6.875″ to measure all but the smallest joints. Unlike standard goniometers that require the examiner to estimate alignment, the length of the extendable arms allows it to lie over anatomical bony landmarks.
The dual scale of 0° to 180° and 180° to 0° is magnified four times, improving the accuracy of the reading, thus, reducing the chance for error. • Total collapsed length: 8″ • Total extended length: 23.5″ • Arm rotation: 360° in both directions
