Effect of equipping an unloader knee orthosis with vibrators on pain, function, stiffness, and knee adduction moment in people with knee osteoarthritis: A pilot randomized trial

Wearing unloader knee orthoses for the long term may have a side effect on knee adduction moment (KAM). This study sought to determine whether equipping an unloader knee orthosis with vibrators improves its effectiveness in pain, stiffness, function, and reducing the KAM. The authors performed a cli...

Description
Summary:Wearing unloader knee orthoses for the long term may have a side effect on knee adduction moment (KAM). This study sought to determine whether equipping an unloader knee orthosis with vibrators improves its effectiveness in pain, stiffness, function, and reducing the KAM. The authors performed a clinical evaluation with the Western Ontario and McMaster Universities (WOMAC) questionnaire and instrumented gait analyses on 14 participants with medial compartment knee osteoarthritis in two testing sessions: before wearing the orthosis and after 6 weeks of use. Wearing both orthoses for 6 weeks significantly improved (p
