This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a need for improved design and function of prosthetic devices to aid walking in persons with transtibial amputations. This dissertation focused on two semi-active ankle-foot prosthetic devices, the Variable Stiffness Foot (VSF) and Two Axis aDaptable Ankle (TADA), which allow users to change biomechanical ankle-foot functions using simpler designs, lower costs, and less power than active prostheses. The background for this dissertation explored the main lower-limb biomechanical principles of prosthetic design, prosthetic-walking mechanics, and sensor feedback. The VSF manuscript investigated the mechanical impact of adjusting stiffness on lower limb mechanics using a prosthetic foot, which can modulate forefoot stiffness. A less stiff VSF resulted in increased ankle dorsiflexion angle, decreased ankle plantarflexor moment, decreased knee extension, decreased knee flexor moment, and increased magnitudes of prosthetic energy storage, energy return, and push-off power. These findings suggest that a less stiff VSF may offer advantages in lower joint moments and greater ankle angle range of motion for individuals with lower-limb prostheses. The Two Axis aDaptable Ankle (TADA) is a semi-active prosthetic ankle that offers independent modulation of sagittal and frontal ankle angles. The first TADA study modified a Raspberry Pi 4 for real-time control of brushless direct-current motors, allowing for precise and reliable ankle angle adjustments. The control system employed CANopen over EtherCAT (CoE) for synchronized communication between the Raspberry Pi and motor controllers. The results demonstrated improved movement times, lower movement errors, and higher data transmission rates. As a continuation, the final TADA study aimed to create an ankle prosthesis that can synchronously record lower-body kinematics and kinetics and assess the sensitivity of those mechanics to different walking speeds and ankle angles for an unimpaired participant. Using a pylon load cell, the results showed that peak magnitudes and impulses increased for plantarflexor moments with increased plantarflexion angle and for evertor moments with increased inversion angles. Moreover, the peak sagittal pylon moments increased with higher walking speeds. The integrated control system of the TADA effectively controls ankle angles, can affect lower-body mechanical outcomes, and can allow for efficient adaptation to various speeds and terrains in users with transtibial amputations.
Download or read book Semi active Damping for an Intelligent Adaptive Ankle Prosthesis written by Andrew Kennedy LaPrè and published by . This book was released on 2012 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern lower limb prostheses are devices that replace missing limbs, making it possible for lower limb amputees to walk again. Most commercially available prosthetic limbs lack intelligence and passive adaptive capabilities, and none available can adapt on a step by step basis. Often, amputees experience a loss of terrain adaptability as well as stability, leaving the amputee with a severely altered gait. This work is focused on the development of a semi-active damping system for use in intelligent terrain adaptive ankle prostheses. The system designed consists of an optimized hydraulic cylinder with an electronic servo valve which throttles the hydraulic fluid flowing between the cylinder's chambers, acting on the prosthesis joint with a moment arm in series with a carbon spring foot. This provides the capability to absorb energy during the amputees gait cycle in a controlled manner, effectively allowing the passive dynamic response to be greatly altered continuously by leveraging a small energy source. A virtual simulation of an amputee gait cycle with the adaptive semi-active ankle design revealed the potential to replicate adaptive abilities of the human ankle. The results showed very similarly that irregularities in amputee biomechanics can be greatly compensated for using semi-active damping.

Download or read book Biomechanics of Lower Limb Prosthetics written by Mark R. Pitkin and published by Springer. This book was released on 2009-10-14 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foreword from a Clinical Biomechanist, Applied Physiologist and Prosthetist teaching graduate students in Prosthetics & Orthotics. While there are many books on Biomechanics, arguably the quintessential science of limb prosthetics, none addresses the fundamental principles in sufficient detail and depth to be practically useful to the prosthetist, rehabilitation specialist or researcher. Dr. Pitkin’s monograph is an exemplary collection of theoretical principles from his research and o- ers, presented in its clinical and applied biomechanics form. The textbook provides an excellent overview of the many facets of lower limb prosthetic design and engineering for the ardent clinician researcher and student. The book delves into many of the basic concepts that are required knowledge for the clinician and the scientist to have as the foundation for their work. Dr. Pitkin has an e- quent manner in which he reflects on the history and literature to tell the storied evolution of prosthetic design . He takes the reader on a journey to consider his theories, which have substantive foundations to contemplate. By the end of chapter one, we have the basic h- tory and an appreciation for the rationale behind the “rolling joint ankle” with evidence to support his theoretical views.
