Look at three important subjects relating to Instrumented Normal and Pathological Gait. Discuss some of the limitations and possible errors associated with assumptions that are associated with marker based motion analysis systems. A novel presentation of gait mechanics drawn directly from instrumented gait research on Stance Control Orthoses and Microprocessor knees will be presented. Subtalor biomechanics will be presented in a highly visual format utilizing graphical representation of motion and force data to illustrate the influence of subtalor motion on gait dynamics. This unique presentation uses normal data and pulls together ideas on subtalor mechanics from across various disciplines in a highly visual format.

Review results of a study to identify the key measures of gait and mobility that best characterize performance differences between prosthetic foot designs. It is also intended to determine the relationship between functional/self report measures and quantitative biomechanics measures of prosthetic foot performance. The relationship between amputee demographic characteristics and prosthetic foot performance of the Transtibial amputee are also addressed.

The Cobb angle has long been the gold standard for measuring and reporting the severity and progression of Idiopathic Scoliosis. The limitation is that it does not address coronal plane deviations such as the relationship of vertebrae to the central sacral line in the coronal plane. Be introduced to a new tool for the assessment of the radiograph in the coronal plane in order to formulate a more appropriate orthosis design and force vectors.
