Footwear Prescription System for Injury Prevention and Management

Tech ID #: 1015.2 CONNECT WITH A MANAGER FOR LICENSING

Description of Technology

Patellofemoral pain syndrome (PFPS) is the most frequently encountered overuse injury in sports medicine clinics. Additionally, it is estimated that one out of two adults will develop symptoms of knee osteoarthritis (OA) during their lifetime. Combined, these two injuries affect well over 25 million people in Canada and the United States, and this number is expected to rise over the next generation. Both injuries are characterized by increased knee joint loading during walking and running, and therefore orthotics are commonly prescribed for the treatment and managment of PFPS and OA to reduce this loading. However, in 15 to 45 per cent of cases, individuals receiving an orthotic will actually experience increased joint loads, possibly contributing to disease worsening. Currently, no method is available for predicting the biomechanical response of a given footwear intervention resulting in the incorrect prescription of potentially hazardous orthotics to millions of individuals each year.

Researchers in the Human Performance Laboratory at the University of Calgary have developed a method for predicting response to a given footwear intervention. The method combines 2D video data and uniaxial ground force data from a single stepping motion to predict biomechanical response at the knee during walking and running. The system has the potential to reduce injury and improve the efficacy of orthodics by using a scientific, precision medicine approach to footwear prescription.
