This book was released on 2010 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over one million amputees are living in the United States with major lower limb loss (Ziegler-Graham et al. 2008). Lower limb amputation leads to the functional loss of the ankle plantar flexor muscles, which are important contributors to body support, forward propulsion, and leg swing initiation during walking (Neptune et al. 2001; Liu et al. 2006). Effective prosthetic component design is essential for successful rehabilitation of amputees to return to an active lifestyle by partially replacing the functional role of the ankle muscles. The series of experimental and computer simulation studies presented in this research showed that design characteristics of energy storage and return prosthetic ankles, specifically the elastic stiffness, significantly influence residual and intact leg ground reaction forces, knee joint moments, and muscle activity, thus affecting muscle output. These findings highlight the importance of proper prosthetic foot stiffness prescription for amputees to assure effective rehabilitation outcomes. The research also showed that the ankle muscles serve to stabilize the body during turning the center of mass. When amputees turn while supported by their prosthetic components, they rely more on gravity to redirect the center of mass than active muscle generation. This mechanism increases the risks of falling and identifies a need for prosthetic components and rehabilitation focused on increasing amputee stability during turning. A proper understanding of the effects of prosthetic components on amputee walking mechanics is critical to decreasing complications and risks that are prevalent among lower-limb amputees. The presented research is an important step towards reaching this goal.

This book was released on 2017 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prosthetists currently lack quantifiable measures to guide prosthesis prescriptions and must rely on experience and manufacturer recommendations. Studies have shown that stiffness and energy storage characteristics of prosthetic feet significantly influence amputee gait. Consequently, several studies have attempted measure these mechanical characteristics, but typically measure only a few orientations in a single plane. This study examined the stiffness and energy storage characteristics of several prostheses over normal gait orientations with the goal of improving prosthesis prescriptions. Feet from five different manufacturers were tested with twenty-five different combinations of foot style, stiffness category and heel wedge inclusion. Force-displacement data were collected at fifteen sagittal orientations and five coronal orientations, and were used to calculate stiffness and energy storage. Loading conditions at each sagittal orientation were determined using a representative amputee’s scaled walking data. Stiffness and energy storage were found to be highly non-linear in both the sagittal and coronal planes. Across all feet, stiffness was greatest near foot flat in the sagittal plane. Generally, stiffness decreased with greater heel, forefoot, medial and lateral loading orientations. Energy storage was greatest for forefoot loading and increased with medial or lateral loading orientations. As stiffness category increased within a foot style, stiffness increased and energy stored decreased. However, the recommended weight for a given foot was not linearly related to stiffness or energy storage. In addition, feet with similar manufacturer recommended weight ranges had varied energy storage over all orientations and varied stiffness over heel and foot flat loading orientations. Inclusion of heel wedges increased stiffness and decreased energy storage over heel and foot flat loading for the Vari-Flex with EVO foot, but not the Sierra foot. These results may help improve clinical prescriptions by providing prosthetists with quantitative measures to compare feet.

Book excerpt: This ground-breaking title begins with an introductory overview of the Lower Extremity Gait Systems (LEGS) project, identifying concerns and observations as context for the reader to consider topics and challenges detailed in later chapters. Next are chapters that explore relevant military and civilian needs, and an essential historical context of the capabilities and limitations of contemporary prosthetics. The section concludes with an overview of essential components used in passive and active lower limb prosthetics, including sockets, foot, ankle, and knee systems, as well as emerging bionic systems. A second section considers research and development in orthotics, synthetic and biological materials, volitional control, and wearable robotics (also known as exoskeletons). Finally, expert authors explore advanced science and emerging medical perspectives in research related to limb salvage, osseointegration, limb transplantation, and tissue engineering. Designed for medical practitioners, engineers, students, and researchers who use or develop prosthetic technology for civilian or military amputees, Full Stride: Advancing the State of the Art in Lower Extremity Gait Systems will be of great interest to trauma specialists, orthopedists, rehabilitation specialists, nursing staff and physical therapists, as well as researchers and scientists who specialize in fields that shape and inform advanced prosthetic device development such as materials sciences, engineering (electrical, mechanical, biomedical), robotics, and human physiology.

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.
