3D Gait Analysis of Kinematic Pattern of Posterior Leaf Spring Orthosis
Introduction:
Gait analysis can be as rudimentary as qualitatively assessing a patient's gait by visual assessment, or it can be as scientific as using sophisticated equipment like accelerometers, high-speed video cameras and optoelectric systems. Sophisticated gait analysis allows us to study human motion and even quantify it into data that can be analyzed and researched. This data can be useful in determining effectiveness of a variety of treatments including the application of a lower extremity orthosis like a PLS AFO (posterior-leaf-spring, ankle-foot-orthosis).
Collecting kinematic data involves "marking" the patient with strategically placed reflectors to identify important articulating skeletal landmarks. These markers reflect light to cameras fixed on the border of the walking runway. Even though the cameras only capture two-dimensional data, they use many computer-driven operations including......
