Download or read book Tuning Prosthetic Foot Stiffness to Improve Lower limb Amputee Mobility written by Courtney Elyse Shell and published by . This book was released on 2016 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The foot, ankle and surrounding musculature play key roles in walking and maneuvering. They provide not only body support but also forward propulsion, terrain adaptation, and contributions to mediolateral balance control. Prosthetic feet have previously been designed to provide body support and, to some degree, forward propulsion and sagittal-plane terrain adaptation. However, there has been little exploration of how prosthesis design affects performance in tasks that challenge mediolateral balance, such as turning and walking on cross-slopes. In Chapter 2, the effects of prosthetic foot stiffness on unilateral transtibial amputee gait during turning were explored. Changes found in sagittal-plane kinematics and kinetics caused by more compliant prostheses were similar to those seen previously in studies of straight-line walking. This included decreased body support, increased residual limb propulsion and greater limb flexion. Mediolateral balance, measured by peak-to-peak range of whole-body angular momentum, improved with decreasing stiffness, but adaptations in coronal-plane angles, work and ground reaction force impulses were less systematic. In Chapter 3, forward dynamics simulations of a unilateral transtibial amputee stepping on a cross-slope were used to identify optimal coronal-plane stiffness profiles that improved balance control by decreasing changes in coronal-plane whole-body angular momentum. Profiles that decreased these changes were identified for ankle-inverting and ankle-everting cross-slopes as well as level ground. The change in coronal-plane whole-body angular momentum decreased with an increase in stiffness for ankle-everting cross-slopes but with a decrease in stiffness for ankle-inverting cross-slopes and level ground. Stiffness profiles influenced mediolateral balance control through the medial GRF, but were specific to each surface type. These results highlight the need to identify the surface type encountered (level, ankle-inverting or ankle-everting cross-slope) so that the stiffness profile appropriate for the surface can be set. To that end, in Chapter 4, measurements from the residual limb useful for predicting a cross-slope with a pattern recognition algorithm were identified. Residual limb kinematics, especially measurements from the foot, shank and ankle, were found to successfully predict the surface type with high accuracy. These studies have provided rationale and foundation for designing prostheses that help maintain mediolateral balance control when encountering turning or uneven terrain.
Download or read book The Influence of Prosthetic Foot Design and Walking Speed on Below knee Amputee Gait Mechanics written by Nicholas Phillip Fey and published by . This book was released on 2011 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unilateral below-knee amputees commonly experience asymmetrical gait patterns and develop comorbidities in their intact (non-amputated) and residual (amputated) legs, with the mechanisms leading to these asymmetries and comorbidities being poorly understood. Prosthetic feet have been designed in an attempt to minimize walking asymmetries by utilizing elastic energy storage and return (ESAR) to help provide body support, forward propulsion and leg swing initiation. However, identifying the influence of walking speed and prosthetic foot stiffness on amputee gait mechanics is needed to develop evidence-based rationale for prosthetic foot selection and treatment of comorbidities. In this research, experimental and modeling studies were performed to identify the influence of walking speed and prosthetic foot stiffness on amputee walking mechanics. The results showed that when asymptomatic and relatively new amputees walk using clinically prescribed prosthetic feet across a wide range of speeds, loading asymmetries exist between the intact and residual knees. However, knee intersegmental joint force and moment quantities in both legs were not higher compared to non-amputees, suggesting that increased knee loads leading to joint disorders may develop in response to prolonged prosthesis usage or the onset of joint pathology over time. In addition, the results showed that decreasing ESAR foot stiffness can increase prosthesis range of motion, mid-stance energy storage, and late-stance energy return. However, the prosthetic foot contributions to forward propulsion and swing initiation were limited due to muscle compensations needed to provide body support and forward propulsion in the absence of residual leg ankle muscles. A study was also performed that integrated design optimization with forward dynamics simulations of amputee walking to identify the optimal prosthetic foot stiffness that minimized metabolic cost and intact knee joint forces. The optimal stiffness profile stiffened the toe and mid-foot while making the ankle less stiff, which decreased the intact knee joint force during mid-stance while reducing the overall metabolic cost of walking. These studies have provided new insight into the relationships between prosthetic foot stiffness and amputee walking mechanics, which provides biomechanics-based rationale for prosthetic foot prescription that can lead to improved amputee mobility and overall quality of life.

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.

Download or read book Handbook of Human Motion written by and published by Springer. This book was released on 2018-04-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Human Motion is a large cross-disciplinary reference work which covers the many interlinked facets of the science and technology of human motion and its measurement. Individual chapters cover fundamental principles and technological developments, the state-of-the-art and consider applications across four broad and interconnected fields; medicine, sport, forensics and animation. The huge strides in technological advancement made over the past century make it possible to measure motion with unprecedented precision, but also lead to new challenges. This work introduces the many different approaches and systems used in motion capture, including IR and ultrasound, mechanical systems and video, plus some emerging techniques. The large variety of techniques used for the study of motion science in medicine can make analysis a complicated process, but extremely effective for the treatment of the patient when well utilised. The handbook descri bes how motion capture techniques are applied in medicine, and shows how the resulting analysis can help in diagnosis and treatment. A closely related field, sports science involves a combination of in-depth medical knowledge and detailed understanding of performance and training techniques, and motion capture can play an extremely important role in linking these disciplines. The handbook considers which technologies are most appropriate in specific circumstances, how they are applied and how this can help prevent injury and improve sporting performance. The application of motion capture in forensic science and security is reviewed, with chapters dedicated to specific areas including employment law, injury analysis, criminal activity and motion/facial recognition. And in the final area of application, the book describes how novel motion capture techniques have been designed specifically to aid the creation of increasingly realistic animation within films and v ideo games, with Lord of the Rings and Avatar just two examples. Chapters will provide an overview of the bespoke motion capture techniques developed for animation, how these have influenced advances in film and game design, and the links to behavioural studies, both in humans and in robotics. Comprising a cross-referenced compendium of different techniques and applications across a broad field, the Handbook of Human Motion provides the reader with a detailed reference and simultaneously a source of inspiration for future work. The book will be of use to students, researchers, engineers and others working in any field relevant to human motion capture.
Download or read book Advances in Technology Assisted Rehabilitation written by Andreas Kannenberg and published by Frontiers Media SA. This book was released on 2024-08-20 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to a 2005 report of the World Health Organization (WHO), an estimated 1.3 billion people worldwide – 16% of the global population – experienced significant disability. This number has only been increasing due to population ageing and an increase in the prevalence of non-communicable diseases. Rehabilitation addresses the impact of a health condition on a person’s everyday life, by optimizing their function and reducing the experience of disability. Rehabilitation ensures people with a health condition can remain as independent as possible and participate in education, work, and meaningful life roles. Global demographic and health trends, such as population ageing, medical staffing shortages, rising prevalence of non-communicable diseases, as well as continued consequences of conflict, injury and developmental conditions are placing increasing demands on the health care systems. The need for quality rehabilitation is rapidly growing, yet in many parts of the world this need is largely unmet.

Available in PDF, EPUB and Kindle. Book excerpt: Bicycles have been a common device to enhance physical fitness level in gyms and training centers along with solid use in competitive sport. For that reason, biomechanics of cycling has grown as a research field with many publications addressing different perspective of the interaction between the cyclist and his bicycle. The most common end point of research on biomechanics of cycling is optimization of performance and reduction of injury risk. One goal of this book is to meet the growing need for a comprehensive presentation of contemporary knowledge on biomechanics of cycling which will positively influence the activity of cycling in a global fashion. In order to accomplish this purpose, ten chapters are presented with focus on varying methods for biomechanical analysis of cycling motion. The introduction section provides an overview of the main methods for assessment of cycling motion, including motion analysis, pedal force measurements, muscle activation, anthropometry and joint kinetics. These methods are discussed in depth in individual chapters followed by chapters on characteristics of bicycles and potential perspectives to improve their configuration in order to improve performance of cyclists and reduce their overuse injury risk. Moreover, a preliminary method to train technique in cyclists is shown. A final chapter provides authors perspective on the upcoming technology that should be effective in helping training of cyclists.
