Description
This plastic goniometer combines a 0–180° protractor with a 6-3/4 inch straightedge to provide angular measurement and linear distance readings. The 0–180° protractor scale advances in 5° increments, and a fixed base with a movable arm allows angle alignment at the joint axis. Along the straight edge, metric and imperial markings offer readings in inches and centimeters for quick correlation of range of motion to limb length. The device is molded from clear, durable plastic to resist wear while remaining lightweight for daily use. Overall length is 6-3/4 inches (17.1 cm). A central pivot and locking mechanism (visible as a small knob) helps stabilize the angle during observation. Designed for clinical settings such as physical therapy and rehabilitation, it supports simple, repeatable measurements of joint motion and score documentation.
