Description
The 6-inch plastic 360 Degree Isom Goniometer is a handheld ROM measurement instrument featuring a circular 360-degree protractor head. The head includes three scales calibrated for use with the Isom system, enabling consistent angular readings during joint assessment.
Two flat measurement arms extend from the dial, providing a stable baseline for alignment with proximal and distal segments. The clear plastic construction permits direct observation of the joint axis of motion and range of motion (ROM) during measurement. Graduations on the protractor and arms offer simultaneous angle and reference-length cues. The instrument is designed for use with Isom-based documentation workflows and standard ROM charts in rehabilitation, physical therapy, and sports medicine.
