Assessment of Gait Adaptation Due to an Asymmetric Walking Protocol
University of Connecticut
Summary
The purpose of this work is to conduct a comparative research-focused study to evaluate the effectiveness of how purposefully induced asymmetric walking protocols restore healthy, symmetric limb loading in individuals following post-anterior cruciate ligament reconstruction (ACLR) surgery. Additionally, computational modeling and machine learning to model knee loading in the clinic to determine the optimal asymmetric walking protocol to restore healthy gait in post-ACLR individuals.
Description
This is an intervention study in which participants will be randomized as to the order in which each of the two sessions are completed. Forty post-ACLR will who present with between-limb gait differences will perform two asymmetric walking sessions where they will walk with between-limb gait speed differences of 0.25 m/s and 0.50 m/s at three 15-minute intervals to evaluate the restoration of healthy gait. Post-ACLR participants will perform an asymmetric walking intervention protocol session on two different days. On one day they will perform the protocol with a 0.25 m/s between-limb differen…

Interventions
- OtherActive Comparator: 0.25 m/s asymmetric session first
Participants will first perform an asymmetric walking trial where the between-limb gait speed difference is 0.25 m/s on day one. On the second day, participants will perform an asymmetric walking trial where the between-limb gait speed difference is 0.50 m/s.
- OtherActive Comparator: 0.50 m/s asymmetric session first
Participants will first perform an asymmetric walking trial where the between-limb gait speed difference is 0.50 m/s on day one. On the second day, participants will perform an asymmetric walking trial where the between-limb gait speed difference is 0.25 m/s.
