The Gollehon Extendable Goniometer is an innovative range of motion assessment tool designed to provide greater accuracy, versatility, and ease of use than traditional goniometers. Its unique extendable arm design allows clinicians to measure both small and large joints with a single instrument, making it ideal for a wide range of clinical and rehabilitation applications.
The extendable arms can be adjusted from 8.0 inches to 28.0 inches, enabling accurate measurements on joints ranging from the wrist and elbow to the hip and knee. Unlike conventional goniometers, which often require clinicians to estimate alignment, the longer arms can be positioned directly over anatomical bony landmarks, improving measurement consistency and reducing user error.
A magnified reading window and dual-scale display (0°-180° and 180°-0°) enlarge the measurement scale by four times, making readings easier to interpret and improving overall accuracy. Constructed from lightweight, durable ABS plastic, the Gollehon Extendable Goniometer is both portable and built for long-term clinical use.
