External Focus of Attention Posttraumatic Osteoarthritis

Knee injuries, especially those to the ACL, are common among physically active people. These injuries are frequently treated with surgical reconstruction (ACL reconstruction; ACLR). While ACLR restores stability it does not protect against future injury, long-term pain, disability, and arthritis associated with these injuries. Our study is going to examine new ways to provide feedback about the way people move to determine if these are better at modifying movement patterns that are known risk factors of posttraumatic osteoarthritis development than current standard treatments. If you participate, you will be asked to undergo a movement analysis in a research laboratory while you perform tasks such as walking and hopping. After this initial assessment, you will be randomly allocated to one of 2 treatment groups. Each treatment group will perform 4 weeks (3x/week) of exercises to change the way people walk. Participants will then report for follow-up movement analysis testing 1- and 4-weeks after completing the intervention.

Treatment and study plan

Internal focus of attention feedback

Other

Participants will complete 12 sessions over a 3-week period of functional movement retraining while receiving mirror feedback. Participants will be instructed to perform each functional task in a manner that keeps their knee in line with their toes.

External focus of attention feedback

Other

Participants will complete 12 sessions over a 3-week period of functional movement retraining while receiving visual feedback via laser. Participants will be instructed to perform each functional task in a manner that does causes the laser to move up and down but not side-to-side.

Primary outcomes

  1. Changes from baseline in lower extremity biomechanics during walking

    Time frame: 1-week post-intervention, 4-weeks post-intervention

    Knee and hip angles and loads measured via 3D biomechanics

  2. Knee cartilage health

    Time frame: 1-week post-intervention, 4-weeks post-intervention

    Knee cartilage thickness measured using diagnostic ultrasound imaging
