Gender:
Health Condition(s) or Problem(s) studied
Total Hip Arthroplasty, Rehabilitation, Instrumented force shoes, Ambulatory measurements

Intervention(s)
Patients undergoing THA will be measured before and 6-8 months after the operation. Both measurements include 3 functional mobility tasks while the subject is wearing instrumented force shoes (IFS). In the first task, the subject is instructed to walk several times through the corridor from the beginning to the predefined endpoint. Subsequently, the subject is asked to stand and sit in a chair with arms folded across the chest 5 consecutive times. The third task is to ascend and descend a total of 5 steps of a stair. Before and after each measurement a Visual Analogue Scale (VAS) will be used to score pain in the hip. Besides the VAS, after each measurement the Harris Hip Score (HHS) and the Functional capacity part of the Traditional Western Ontario and McMaster Universities osteoarthritis index (WOMAC-FC) will be administered.
Primary Outcome(s)
The first aim of this study is to investigate whether the IFS is a sufficiently sensitive instrument to show differences in mobility performance between before and after THA.
Secondary Outcome(s)
The second objective is to compare the IFS parameters to the gait velocity (assessed independently from the IFS) and questionnaire outcomes.
