Research Interests

Dr. Carollo is interested in improved gait analysis methods, mathematical modeling of locomotion, measurement of dynamic center of gravity displacement, and characterization of neuromuscular stiffness. He furthers this research through the Center for Gait and Movement Analysis (CGMA), the first and only clinical movement analysis laboratory in Colorado and the only program at Children's Hospital to evaluate both children and adults. The CGMA's mission is to comprehensively analyze movement disorders associated with neuromuscular and orthopedic conditions using advanced measurement tools and a unique multidisciplinary approach. The goal is to identify critical gait abnormalities and recommend comprehensive treatment to restore functional ambulation in any individual with less than optimal walking performance.
