Anterior Cruciate Ligament Reconstruction Clinical Trial
Official title:
Assessment of Gait Adaptation Due to an Asymmetric Walking Protocol
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.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change in Loading Rate | The rate at which the force is generated (Body Weight/sec). A decrease in loading rate would suggest that the participants adopted improved motor control while an increase would reflect impaired of motor control. | Screening, Baseline, and Post-Treatment (immediately following the completion of the second session) | |
Primary | Change in Peak Vertical Ground Reaction Force | The largest force (newtons) produced during stance. An increase in force would that the participants are not properly engaging their muscles to control their movement. | Baseline, Post-Treatment (immediately following the completion of the second session) | |
Primary | Change in Stride Time | The time (seconds) measure from initial contact on the foot to the next initial contact on the same foot. A reduction in stride time would indicate that the participants are walking faster and more comfortable applying force to their limb during walking. An increase in walking speed, suggests that the participants are uncomfortable applying force to their limb. | Baseline, Post-Treatment (immediately following the completion of the second session) | |
Primary | Change in Knee Loading | The forces (newtons) experienced at the knee. An increase in knee loading would indicate that they participants are unable to properly support their knee during walking, while a reduction in knee loads would indicate the participants are engaging the appropriate muscles to support their knee during walking. | Baseline, Post-Treatment (immediately following the completion of the second session) |
