Those transparent plastic goniometers permits observation of a joint's axis of motion and its range of motion. The unique design adds a white line behind the measurement gradations to make the readings even easier to read. 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 180 degree 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. Suitable for home use as well as multi-user environments. 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 180 degree angle scale reads 1 degree increments. The clear plastic of the goniometer allows the device to be placed directly and exactly on a joint or limb for easy observation. This Goniometer is a Baseline product, which means it's a trusted name in measurement and evaluation instruments.Available in the following length: 12-1005HR: 6", pocket style 12-1012HR: 5.5", Flexion to hyper extension
