This book was released on 2012 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Musculoskeletal simulations of movement are often used to estimate soft tissue and joint contact loads. However, traditional modeling approaches do not incorporate knee laxity, which could affect both kinematic and kinetic estimates. The first objective of this study was to empirically assess how in vivo knee kinematics vary with quadriceps loading. Dynamic magnetic resonance imaging was used to track knee kinematics during a cyclic task in which quadriceps activity was induced with knee extension or flexion. The results show that quadriceps loading in a flexed knee induces a significant inferior shift of the finite helical axis of the tibiofemoral joint, which diminishes the patellar tendon moment arm about the knee. The second objective was to investigate whether a muscle-actuated computational knee model that includes ligament compliance and tibiofemoral contact could emulate in vivo kinematic patterns. A co-simulation framework was implemented in which neuromusculokeletal dynamics and knee mechanics were simultaneously solved. The co-simulation model predicted similar load-dependent variations in knee kinematics as seen in vivo, with predictions being dependent on both ligament compliance and the loading state. The final objective was to use the co-simulation framework to investigate the influence of knee laxity on tibiofemoral kinematics and kinetics during walking. Muscle activation patterns were computed that drove a lower extremity musculoskeletal model to track normal hip, knee, and ankle flexion patterns during gait. During the load acceptance phase of gait, the models with laxity predicted increased anterior tibia translation and internal tibia rotation due to quadriceps loading. These variations in tibiofemoral kinematics resulted in a more inferior finite helical axis, a diminished patellar tendon moment arm, and increased quadriceps loading, relative to what would be computed using a traditional kinematic knee model. Simulating gait with an ACL-deficient knee shifted tibia plateau cartilage contact posteriorly and laterally, which is a biomechanical affect that could contribute to early onset knee osteoarthritis. It is concluded that a co-simulation framework that incorporates joint laxity is important when using models to predict the effect of injury, surgical, and rehabilitation strategies on knee mechanics during human movement.

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 Musculoskeletal Disorders and the Workplace written by Institute of Medicine and published by National Academies Press. This book was released on 2001-05-24 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year workers' low-back, hand, and arm problems lead to time away from jobs and reduce the nation's economic productivity. The connection of these problems to workplace activities-from carrying boxes to lifting patients to pounding computer keyboards-is the subject of major disagreements among workers, employers, advocacy groups, and researchers. Musculoskeletal Disorders and the Workplace examines the scientific basis for connecting musculoskeletal disorders with the workplace, considering people, job tasks, and work environments. A multidisciplinary panel draws conclusions about the likelihood of causal links and the effectiveness of various intervention strategies. The panel also offers recommendations for what actions can be considered on the basis of current information and for closing information gaps. This book presents the latest information on the prevalence, incidence, and costs of musculoskeletal disorders and identifies factors that influence injury reporting. It reviews the broad scope of evidence: epidemiological studies of physical and psychosocial variables, basic biology, biomechanics, and physical and behavioral responses to stress. Given the magnitude of the problem-approximately 1 million people miss some work each year-and the current trends in workplace practices, this volume will be a must for advocates for workplace health, policy makers, employers, employees, medical professionals, engineers, lawyers, and labor officials.

Download or read book Soft Tissue Biomechanical Modeling for Computer Assisted Surgery written by Yohan Payan and published by Springer Science & Business Media. This book was released on 2012-04-27 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the biomechanical modeling of biological tissues in the context of Computer Assisted Surgery (CAS). More specifically, deformable soft tissues are addressed since they are the subject of the most recent developments in this field. The pioneering works on this CAS topic date from the 1980's, with applications in orthopaedics and biomechanical models of bones. More recently, however, biomechanical models of soft tissues have been proposed since most of the human body is made of soft organs that can be deformed by the surgical gesture. Such models are much more complicated to handle since the tissues can be subject to large deformations (non-linear geometrical framework) as well as complex stress/strain relationships (non-linear mechanical framework). Part 1 of the volume presents biomechanical models that have been developed in a CAS context and used during surgery. This is particularly new since most of the soft tissues models already proposed concern Computer Assisted Planning, with a pre-operative use of the models. Then, the volume addresses the two key issues raised for an intra-operative use of soft tissues models, namely (Part 2) “how to estimate the in vivo mechanical behavior of the tissues?” (i.e. what are the values of the mechanical parameters that can deliver realistic patient-specific behavior?) and (Part 3) “how to build a modeling platform that provides generic real-time (or at least interactive-time) numerical simulations?”
