Biomechanical analysis of indicators of movements in the joints of the lower extremity in patients with coxarthrosis as a method of functional diagnosis

Abstract


Biomechanical parameters of the movements of patients with different stages of idiopathic, posttraumatic coxarthrosis and
with avascular necrosis were studied. Low limb movements were recorded with electromagnetic system. Angular amplitudes,
angular velocities and parameters of joint stiffness and joint flexibility were calculated using movement recordings and
previously developed biomechanical model. It was shown that these parameters adequately describe the stage of hip joint
injury. As for patients with early stages of coxarthrosis, these parameters describe the differences between the limb under
suspicion and the intact limb. The proposed biomechanical parameters can be used as the numerical assessments of a
functional state of the low limb under coxarthrosis: for a diagnostics, including early one, for an assessment of the results of  operative interventions, for an assessment of the effectiveness of rehabilitation procedures
