This transparent plastic goniometer permits observation of a joint's axis of motion and its range of motion. The primary purpose of this device is to assist in physical therapy by determining range of motion of a joint as well as evaluating and gauging recovery after surgery or physical therapy. The 360° head has three scales calibrated to be used with the ISOM (International Standards of Measurement, STFR) system. This is an essential tool for treatment, rehab and surgical recovery and evaluation. Given its convenient shape and size, this is suitable for home use as well as multi-user environments. The arms are 6". This goniometer lets you measure joint limits and range-of-motion as well as check extension, flexion, abduction, adduction and rotation. The arms have a linear scale in both inches and centimeters. They also will remain at the last measurement position until reset. The 360° angle scale reads 1° increments. The clear plastic of the goniometer allows the device to be placed directly and exactly on a joint or limb for easy observation
