Can the use of Proprioceptive Knee Braces have Implications in the Management of Osteoarthritic Knees: An exploratory study?

Abstract

Background: Use of proprioceptive knee braces to control symptomology by altering neuromuscular control mechanisms has been shown in patellofemoral pain. Though their potential in patients with knee osteoarthritis (OA) is vast, little research has examined their efficacy. Methods: Thirteen healthy participants were asked to perform a 10cm stepdown task with and without a Proprioceptive Brace. Data was collected using a 10-camera Qualisys system. Individuals with OA completed the Knee Osteoarthritis Outcome Score (KOOS) pre- and post 4-week intervention. Results: During stepdown reductions in knee maximum internal rotation, transverse range of movement, transverse plane angular velocity and maximum internal rotation angular velocity was seen. Ankle plantar flexion and inversion angular velocity decreased while inversion and maximum supination angular velocity increased. Improvements in KOOS were noted across all parameters with brace use. Conclusions: Positive changes in kinematic variables in multiple planes can be achieved with proprioceptive bracing alongside improved patient outcome. These changes occur at the knee but analysis of other weight bearing joints should not be overlooked in future studies. This study supports the concept of neuromuscular reinforcement and re-education through proprioceptive bracing and its application in the management in knee OA.
