INJURY DEGREE MEASURING DEVICE FOR LIGAMENT IN KNEE JOINT PART

摘要

PROBLEM TO BE SOLVED: To prevent the production of a measurement error by pressing the calf by a calf pressing body to impart a forward pulling force to the joint part ligament of the knee, pressing the upper surface of the patella to impart a backward pressing force, and measuring the forward movement of the tibia scabrous. SOLUTION: A sheet support base 3 is fixed to a base 1, a knee support base 3 and an ankle support base 5 are mounted, and a seat 8 and a seat back 9 are mounted on the upper end of the sheet support base 3. A forward pulling force applying mechanism 100, a backward pressing force imparting mechanism 200, and a measuring means 300 are provided on the knee support base 4, the calf of a subject is pressed forward by the calf pressing body 108 of the forward pulling force applying mechanism 100 to impart a forward pulling force to the joint ligament of the knee, and the upper surface of the patella placed on a hamstring support base is pressed by the backward pressing force imparting mechanism 200 to impart a backward pressing force to the patella. The forward movement of the vertically moved tibia scabrous is measured according to the displacement of the upper surface of the patella by the measuring means 300.
