Kinematic analysis of gait in patients with hip osteoarthrosis

Author: Barbora Říhová Title: Kinematic Analysis of Gait in Patients with Hip Osteoarthrosis Objectives: The aim of this thesis was to analyse the gait patterns in probands with Stage III osteoarthritis of the hip joint, to compare these patterns with published norms and to confirm a set of pre-established hypotheses. Method: The thesis was designed as a case study, the purpose of which was to observe changes in the pelvis and trunk extension during gait, associated with significant degenerative changes in the hip joint. A total of 9 probands with Stage III osteoarthritis of the hip joint (6 females, 3 males) took part in the study. A complete physiotherapy assessment was carried out as part of the study. The temporal gait parameters were used to measure the probands' walking speed and relative stance phase duration. The following variables were measured in the frontal plane: lateral displacement of the pelvis and trunk toward the stance limb (cm) and pelvic obliquity toward the swing limb (degrees). A 3D motion analysis and evaluation of kinematic parameters were carried out using the Qualisys motion capture system device consisting of 6 infrared cameras. Gait was measured at different walking speeds during a 10-second time frame and the data was subsequently subtracted from a minimum of 5 gait..
