Originating from QL+'s customer requirements, the main technical specifications were to have 80% physiological range of motion, elastic energy return, impact absorption, and no external power sources. Based on the background research conducted and the discussions with experts in the field, the project team decided to focus on designing a prosthetic that focused on plantarflexion and dorsiflexion for a more comfortable gait. The main components of the final design are a hydraulic shock absorber, cam, torsion springs, heel, stopper, and separated keel. The heel, front and back keels, and stopper were manufactured out of carbon fiber. The link, lever, attachment …

Orthotic devices are a conservative treatment for common disorders of the foot and ankle such as pes planus and pes cavus. It is thought that orthotics change the kinematics of the foot by applying forces and constraint on the plantar surface, which can act to change body biomechanics and correct for malalignment in the legs and trunk. This thesis compares the angle of the medial longitudinal arch (MLA) between three foot types: pes planus (low arch), pes cavus (high arch) and normal arch, during barefoot and shoed walking, and walking with orthotics. In-vivo bi-planar fluoroscopy was used with markerless radiostereometric …
