There is a test to evaluate the torsion of the tibia as a test method for inner thigh gait. The torsion state of the tibia relative to the femur is measured with a special protractor. The elementary school student (9 years old) in this photo had an internal twist of 12 degrees in his left leg and an external twist of 8 degrees in his right foot. Since the left side twist is a little strong, I treated the twist of the trunk and made a treatment plan that included exercises that allowed me to use the floor reaction force firmly. The following is about the general tibial torsion test and its evaluation For tibial torsion，There are outward twists (external twists) and inward twists (internal twists). External twisting of the tibia is a normal phenomenon that occurs with growth.，It varies from 0° at birth to 20° in adulthood. External twisting is rarely a problem. Internal twisting is commonly seen at birth,，Typically disappears with growth. however，Excessive torsion can be due to problems with the neuromuscular system. Torsion can also occur with Blount's disease ( hip，legs，and congenital anomalies of the feet : varus knee and valgus knee). If excessive torsion persists for a long time，It may come with internal rotation gait or O-legged. To evaluate tibial torsion，The angle between the axis of the foot and the femoral axis will be measured with the knee joint flexed at 90° in the prone position. Typically，The axis of the foot is facing 10° outward to the femoral axis. Director Naoaki KizuLanguageThis page was automatically translated. Please note that it may differ from the original content.
