Estimated Enrollment: 60
Study Start Date: November 2002
Study Completion Date: June 2003
Primary Completion Date: June 2003 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions

Gait analysis, knee x-rays, and knee MRIs will be done twice for each participant, 1 week apart.

Detailed Description:

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.
