IMPAKT-HiPPreventing Hip Pain
About Phase 2: The Case-Control Project
Why do this research project?
Occurring most commonly in younger and middle-aged people, femoroacetabular impingement (FAI) is a common condition in the hip joint.
IMPAKT-HiP researchers believe that physical activities that involve flexing the hip more than 90 degrees (e.g. household chores, sports) could aggravate FAI, causing hip pain and eventually leading to hip OA.
The Case-Control Project will identify which specific kinds of physical/household activity could contribute to the likelihood of a person living with FAI developing hip pain. It will also determine if these aggravating activities are linked with how often or how long a person with FAI performs the activity.
What was done?
More than 500 people aged 19-49 who have persistent or recurring bouts of hip pain received a physical exam, an x-ray and filled out a questionnaire. A questionnaire asked about:
- work, household, sport and recreational activities
- previous injuries
- how long and how often the hip is bent a lot (over 70 degrees) like in squatting and kneeling
- prolonged sitting
The researchers are using computer models to see how physical motion and FAI may combine to cause hip pain.
