Arthrodial Protractor

The Arthrodial Protractor, a measuring device for joint flexibility, is acclaimed to be a top quality instrument that enables one to quickly and accurately test the range of motion in all major joints of the body. It was designed for speed and ease of handling by Reedco Research, manufacturers of anatomical measuring devices. The Arthrodial Protractor is made from transparent, heavy gauge aircraft plexiglass. Accuracy is insured by the built-in stabilizer bubble and the large, easy-to-read red and black degree markings. The Arthrodial Protractor is widely used by the medical paramedical and physical education fields and has proven itself to be an invaluable tool in remedial work, industrial accident cases and insurance examinations. Normalcy, disability or feigning, can be readily demonstrated and since there are no moving parts, one examiner can easily measure all active or passive movements unaided. The instructions include a table of the joint limitation norms.
