Are Patient-Specific Joint And Inertial Parameters Necessary For Accurate Inverse Dynamics Analyses Of Gait?, Jeffrey A. Reinbolt, R. T. Haftka, T. L. Chmielewski, B. J. Fregly Jan 2007

Are Patient-Specific Joint And Inertial Parameters Necessary For Accurate Inverse Dynamics Analyses Of Gait?, Jeffrey A. Reinbolt, R. T. Haftka, T. L. Chmielewski, B. J. Fregly

Variations in joint parameter (JP) values (axis positions and orientations in body segments) and inertial parameter (IP) values (segment masses, mass centers, and moments of inertia) as well as kinematic noise alter the results of inverse dynamics analyses of gait. Three-dimensional linkage models with joint constraints have been proposed as one way to minimize the effects of noisy kinematic data. Such models can also be used to perform gait optimizations to predict post-treatment function given pre-treatment gait data. This study evaluates whether accurate patient- specific JP and IP values are needed in three-dimensional linkage models to produce accurate inverse dynamics …

Gait modification is a nonsurgical approach for reducing the external knee adduction torque in patients with knee osteoarthritis (OA). The magnitude of the first adduction torque peak in particular is strongly associated with knee OA progression. While toeing out has been shown to reduce the second peak, no clinically realistic gait modifications have been identified that effectively reduce both peaks simultaneously. This study predicts novel patient-specific gait modifications that achieve this goal without changing the foot path. The modified gait motion was designed for a single patient with knee OA using dynamic optimization of a patient-specific, full-body gait model. The …
