Official title
Gait Initiation and Transition From Double to Single Support in Patients With Unilateral Primary Coxarthrosis Who Have Not Undergone Surgery and Before/After Arthroplasty
Overview
The study consists to evaluate the impact of prosthetic surgery (PTH and RTH) on kinematic and dynamic parameters (joint torques) of the lower limbs during gait initiation in patients with primary coxarthrosis. Patients included in the study will undergo a three-dimensional gait analysis. Dynamic gait analysis is multidimensional, measuring kinematic parameters (joint amplitudes: ankles, knees, hips, etc.) and dynamic parameters (assessment of joint torque from ankle, knee, hip to lower limb during gait initiation).
Interventions
- Other Patients with primary coxarthrosis (any stage).
Patients who do not undergo surgery will be called specifically for the study to attend a consultation dedicated to gait assessment. - Other Patients with primary coxarthrosis (any stage) and operated with Total Hip Prosthesis (THP).
Patients scheduled for THP (Total Hip Prosthesis) will be seen at the consultation the day before surgery, in the same hospital as the THP, or at an existing dedicated consultation scheduled for all THP patients. During these scheduled visits, they will be received in the gait analysis laboratory for a gait assessment (V1). Patients will be seen again at 6 months post-operatively for a second gait assessment (V2). - Other Patients with primary coxarthrosis (any stage) and operated with RTH (Hip resurfacing).
Patients scheduled for RTH (Hip Resurfacing) will be seen at the consultation the day before surgery, in the same hospital as the RTH, or at an existing dedicated consultation scheduled for all RTH patients. During these scheduled visits, they will be received in the gait analysis laboratory for a gait assessment (V1). Patients will be seen again at 6 months post-operatively for a second gait assessment (V2).
