The inclinometer precisely measures, tests and evaluates the range-of-motion of necks, hips, spines, elbows, knees, shoulders, ankles, wrists and MCP joints. To use, place the inclinometer near the joint to be measured. As the joint gets manipulated, the range-of-motion displays (in degrees) directly on the dial. The inclinometer is ideal for plotting curvature of the spine as well as measuring lateral movement. The inclinometer can measure the entire range of Flexion, Extension, Abduction, Adduction, Dorsiflexion and Plantarflexion. The included protective carry case ensures security for travel and everyday storage. Also included is a detailed instruction manual. Standards codified in AMA Guide to the Evaluation of Permanent Impairment, third edition.
