Introduction Load distribution shifts from the lateral to the medial compartment is related to an increase in knee adduction moment (KAM) and is associated with knee osteoarthritis (OA). previously, reduction in KAM occur when barefoor plantar pressure is medialized. This supports the role of altering kinematics of the forr to redistribute loads across the knee joint.
Successfully gait retaining to medialize plantar pressure and lower KAM have been achieved in the laboratory via auditory feedback provided by a high resolution insole with specifically arranged sensor areas. However, such a plantar pressure detecting system is comprised of multiple electronics and cables and therefore is unsuitable for gait training in the community. With the ultimate goal of translating pressure based feedback training into the clinical setting for sufferes of knee OA, the current study employed a pair of fully integrated, slim 13-sensor insoles (OpenGo, Moticon GmbH, Munich, Germany) for measuring and recording real-time plantar pressure distribution and recording real-time plantar pressure distribution. A smartphone receives sensor data via ANT wireless technology and provide instant auditory feedback. Further exploration of using this sensor insole to provide auditory feedback to lower KAm outside of the laboratory is warranted.
In this study, we hypothesize that gait training using auditory feedback from a cable less commercially available insole in the in the community will reduce KAM.
