Repeatability of X-Ray, MRI, and Gait Analysis
The purpose of this preliminary substudy to the parent study "Aerobic Exercise Intervention for Knee Osteoarthritis" is to determine the repeatability and reproducibility of various measurement techniques.
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Repeatability of X-Ray, MRI, and Gait Analysis|
- Day-to-day and inter/intra examiner repeatability of the techniques to be used in NIH grant R01 AR48768 [ Time Frame: Measured two times, with a 1-week period between evaluations ] [ Designated as safety issue: No ]
|Study Start Date:||November 2002|
|Study Completion Date:||June 2003|
|Primary Completion Date:||June 2003 (Final data collection date for primary outcome measure)|
Healthy adult participants with no history of knee injury or osteoarthritis.
Other: Gait analysis, knee x-ray, and knee MRI
Gait analysis, knee x-rays, and knee MRIs will be done twice for each participant, 1 week apart.
The purpose of this preliminary substudy to the parent study "Aerobic Exercise Intervention for Knee Osteoarthritis" is to determine the repeatability and reproducibility of various measurement techniques. The study will enroll healthy volunteers. All participants will receive x-rays and MRI examinations of the knees. Walking characteristics will be evaluated in a Motion Analysis Lab; this will involve taping reflective markers to participants' skin and having them walk on a level surface and up and down stairs. All participants will be evaluated two times, with a 1-week period between evaluations.
