Gait Modification for Knee Osteoarthritis (SENSMOD)

15 de octubre de 2020 actualizado por: Michael Hunt, University of British Columbia

Foot Progression Angle Modification: an Exploratory Six-week Intervention in People With Knee Osteoarthritis

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.

Descripción general del estudio

Descripción detallada

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.

Armas e Intervenciones

Grupo de participantes/brazo
Intervención / Tratamiento
Experimental: Specific Modification Target
A 15 degree relative increase to foot progression angle
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.
Experimental: Self-directed Modification
A self-directed increase to foot progression angle that is "as much as is comfortable".
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.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Change in baseline to week 7 foot rotation angle error during stance - in lab walking
Periodo de tiempo: Baseline, Week 7
Foot rotation is the specific walking parameter that will be modified during the intervention. It is defined as the angle between the long axis of the foot (heel to toe) and the walking direction. Foot rotation will be measured via standard marker-based motion capture and sensor-based motion capture during baseline, follow up, and each practice session.
Baseline, Week 7
Weekly change in baseline foot rotation angle error during stance - at home walking and during practice sessions
Periodo de tiempo: Baseline, Weeks 1, 2, 3, 4, 5, 6, 7
Foot rotation is the specific walking parameter that will be modified during the intervention. It is defined as the angle between the long axis of the foot and the walking direction. Foot rotation will be measured via sensor-based motion capture over each week of the intervention. Median and inter-quartile ranges will be taken as the primary summary statistic.
Baseline, Weeks 1, 2, 3, 4, 5, 6, 7

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Change in baseline to week 7 knee joint moment impulse
Periodo de tiempo: Baseline, Week 7
Knee flexion and adduction moment impulses will be calculated. Participants will walk on an instrumented walkway (2 force platforms) while 14 high speed cameras track the trajectories of markers placed on boney landmarks. Moments will be calculated using an inverse dynamics approach.
Baseline, Week 7
Change in baseline to week 7 Knee Injury and Osteoarthritis Outcome Score (KOOS)
Periodo de tiempo: Baseline, Week 7
Validated questionnaire on symptoms and functional limitations related to knee osteoarthritis. The score is expressed in percentage (0-100), with 0 representing extreme knee problems and 100 representing no knee problems.
Baseline, Week 7
Change in baseline to week 7 knee pain on a numerical rating scale
Periodo de tiempo: Baseline, Week 7
Knee pain rated on a 0 to 10 scale. 0 = "no pain at all" and 10 = "worst pain imaginable".
Baseline, Week 7
Change in week 1 to week 7 difficulty performing the modification on a numerical rating scale
Periodo de tiempo: Week 1, 7
Difficulty will be rated on a 0 to 10 scale. 0 = "no difficulty at all" and 10 = "most difficulty imaginable".
Week 1, 7
