DIFFERENTIAL DIAGNOSTIC TECHNIQUE OF FUNCTIONAL AND ANATOMIC LENGTH DIFFERENCE OF LOWER EXTREMITIES Russian patent published in 2013 - IPC A61B5/00 A61B5/103 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely locomotor biomechanics. A method involves the following stages: the first stage involves a standing flexion test with a patient standing one a strictly horizontal surface with his/her legs apart. An optimal feet distance makes 10-12 cm. Tangential lines to median edges of feet generate an angel of 10-12° to an axial line. The length difference of the lower extremities is stated in case of observing an advance phenomenon of a posterior superior iliac crest on the side of a 'shorter' leg. At the second stage, the first stage is performed once again with the patient standing on the horizontal surface made of a material flexible under body weigh compression. If the observed advance phenomenon of the posterior superior iliac crest on the side of the 'shorter' leg disappears, the functional length difference of the lower extremities is stated. If the observed advance phenomenon of the posterior superior iliac crest on the side of the 'shorter' leg persists, the anatomical length difference of the lower extremities is stated.

EFFECT: technique provides higher measurement accuracy in the length differences of the extremities.
