Kinematic analysis of locomotor system in persons with abnormal position of the hip joint.
Zahradník, Petr ; Kolář, Pavel (advisor) ; Janura, Miroslav (referee)
Femoroacerabular impingement (FAI) syndrome is a hip joint impairment, which occurs frequently as a result of repeated overloading of the joint in combination with the imperfect orientation of the articulating surfaces. Therefore, it does not respect the biomechanically optimal position of the joint. Currently, many experts consider FAI as an important factor contributing to hip degeneration with the subsequent coxarthrosis. In our research, we evaluated how the FAI translates into normal walking. We used 3D kinematic motion analysis as an objectivization method. Objective: The study aimed to objectify changes in basic walk parameters, lower limb joint and pelvic movements in normal walking in people with FAI using 3D kinematic analysis and to compare the results with a group of healthy people. Sample: 21 patients (7 females, 14 males) were selected for the study with the confirmed FAI by clinical examination and X-ray. The control group consisted of 18 healthy probands (8 females, 10 males) in whom the hip joint morphology by MRI was excluded. Methods: All probands underwent walking examination using 3D kinematic motion analysis using the Qaulisys system. Data were processed by the Qualisys Track Manager and the Visual3D software. The subject of the examination was the basic walk parameters, ankle...
