Summary

This randomized clinical trial will compare the changes in performance, biomechanical and clinical outcomes before and after a six-week gait modification intervention. Participants with knee osteoarthritis will attend in-lab assessments and practice, while also performing daily, at-home walking tracked using a custom sensorized shoe.

Detailed description

Greater toe-in or toe-out angles during walking are potential biomechanical management strategies for medial compartment knee osteoarthritis (OA). Multi-week clinical trials demonstrate the biomechanical efficacy and potential clinical efficacy. However, walking biomechanics have only been assessed within laboratory environments and performance of the modifications during daily at-home walking is currently unknown. Furthermore, the modifications have largely been instructed using a specific target, requiring motor learning. No study has examined whether a self-directed strategy is feasible and will produce significant improvements in biomechanical and clinical outcomes. Moreover, objective real-world performance of these modifications is unknown and may explain the previous inconsistent clinical results. This study will address these gaps. The investigators hypothesize that real-world performance of the modifications will improve over the intervention and that both groups will exhibit improvements in biomechanical and clinical outcomes at follow up.

Conditions

• Osteoarthritis, Knee

Interventions

Type	Name	Description
BEHAVIORAL	Specific Modification Target	Participants will be instructed to increase their baseline foot progression angle by 15 degrees. Visual feedback during practice will be delivered using a mirror and guideline (tape placed on mirror). Verbal feedback will be incorporated to encourage participants to perform the modified foot progression angle as accurately as possible.
BEHAVIORAL	Self-directed Modification	Participants will be instructed to modify their foot progression angle as much as is comfortable. A mirror will be used during practice for visual feedback, but no specific target or guide will be provided.
