Study Details

Brief summary:

The goal of this clinical trial is to compare the effects of different exercises programs in individuals with abnormal knee motion. The main question it aims to answer are:

  • In individuals with abnormal knee motion and without knee pain, does a weight-bearing exercise program reduce abnormal knee motion during a step-down test better than a non weight-bearing exercise program? Participants will
  • Perform a stepdown test while undergoing motion analysis and electromyograph (EMG) recording.
  • Participants will then be placed either into a weight-bearing or non weight-bearing exercise group. Exercises will be performed 3 times per week for 6 weeks.
  • Further motion analysis and EMG data will be collected to test for differences. Researchers will compare individual results before and after exercise, and between-group results before and after exercise to see if one exercise program helps improved abnormal knee motion more than the other.
