Download or read book Ankle Kinetics During Landing Tasks in Participants with Chronic Ankle Instability and Uninjured Controls written by Alison Lorinda Bauer and published by . This book was released on 2006 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: Lateral ankle sprains are a common injury sustained by physically active individuals. Many of these individuals will incur repetitive episodes of lateral ankle sprain, resulting in chronic ankle instability (CAI). CAI has been heavily researched, but few conclusions have been drawn. Much of this research has focused on sagittal plane kinematics and kinetics. Therefore, the purpose of this study was to compare three-dimensional ankle joint kinetics during functional landing tasks in participants with CAI and uninjured controls. Participants performed single-leg vertical drop landings and single-leg cross-over landings. There were no significant diffferences between the two groups for ankle net joint moments (plantarflexion/dorsiflexion, inversion/eversion, internal/external rotation) and ankle net joint forces (axial, anterior/posterior, medial/lateral) at any time point from ground contact to 150 ms after. We conclude that those with CAI do not suffer from an alteration in motor programming, and are able to absorb forces upon landing similar to uninjured individuals.

This book was released on 2014 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Altered gait kinematics and kinetics have been examined in subjects with chronic ankle instability (CAI). Altered vertical ground reaction forces (GRF) have been found in individuals with CAI compared to control subjects, in different movement patterns but not running. Running is a common component of numerous sporting events where ankle sprains occur. The purpose of this investigation was to determine if subjects with CAI produced altered vertical GRF compared to uninjured subjects while running. Specifically, we examined if differences existed in impact peak forces, time to the impact peak force, active peak forces, time to the active peak force and average loading rate between groups. Twenty-four subjects with previous running experience were recruited from a Midwestern community. Subjects were determined to have CAI if they met the following criteria: (1) a history of at least one self-reported lateral ankle sprain that occurred 12 months prior to study enrollment, (2) a history of recurrent sprains or feelings of “giving way” during functional activity, (3) a score of 11 or higher on the Identification of Functional Ankle Instability (IdFAI) Questionnaire. Control subjects had no history of lateral ankle sprains. All subjects were required to be active runners and rear foot strikers ... Overall, results of the study found that individuals with subjects with CAI produce altered GRFs than uninjured subjects while running.

This book was released on 2018 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chronic ankle instability (CAI), a pathological condition characterized by repetitive bouts of the ankle giving way, commonly develops following a lateral ankle sprain injury. Individuals with CAI have been shown to exhibit deficits in postural control and alterations in movement dynamics, which have been suggested to be contributing factors to the recurrent injury paradigm. The purpose of this investigation was to conduct a comprehensive biomechanical analyses to examine the influence of CAI on postural control and movement dynamics during a single leg squat, side-cut task, and single leg landing on an inverted surface. Fifteen participants with CAI and fifteen participants without CAI completed the study following a between-subjects design, with limb serving as the repeated measure during the single leg squat. Each participant completed a single leg squat, side-cut task, and unexpected and expected single leg landings on a tilted surface. Results from the single leg squat and single leg landings on the tilted surface were analyzed using a 2 x 2 mixed-model ANOVA, while results from the side-cut task were analyzed using an independent samples t-test. Statistical significance was considered for all dependent variables when p

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 Biomechanical Performance and Relevant Mechanism of Physical Medicine and Rehabilitation for Neuromusculoskeletal Disorders written by Qipeng Song and published by Frontiers Media SA. This book was released on 2023-11-23 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomechanical performance is a key to evaluating effectiveness in physical medicine and rehabilitation for neuromusculoskeletal disorders. Assessments can be applied to degenerative dysfunction (e.g., falls or knee osteoarthritis in older adults) and sports-related injuries (e.g., ankle sprain or anterior cruciate ligament injury). Patients' body movements and daily activity functions can be compared to the state of pre-injury condition or to the level of healthy individuals. Some cutting-edge studies have gone a step further and used biomechanical performance to develop physical medicine and rehabilitation approaches and explore the mechanisms behind their effectiveness. However, such studies are still relatively rare. This research topic is intended to encourage more relevant projects to be published. This research topic aims to encourage researchers to use biomechanical performance to design advanced physical medicine and rehabilitation approaches, evaluate the effectiveness of the rehabilitation approaches, and explore the mechanisms by which rehabilitation approaches work for neuromusculoskeletal disorders. Some studies have developed stretching approaches for the rehabilitation of knee osteoarthritis in older adults by measuring biomechanical performance during functional activities. Some studies indicated that the mechanism of physical activity to reduce falls in older adults lies in its effectiveness in increasing proprioceptive sensitivity, and further indicated that rehabilitation of proprioception may be a key to reducing falls in the fall-prone older adult population. Some other studies analyzed biomechanical performance in ankle ligament injuries to understand when, how, and why ligaments fail. As a result, this research topic will expand the application of biomechanical performance to better understand and treat neuromusculoskeletal disorders.
