Book Description
Abstract: PURPOSE: The purpose of our study was to determine if a relationship exists between plantarfiexor and dorsiflexor strength and spatial and temporal gait parameters including velocity, cadence, step length, and single limb support, in the older adult. BACKGROUND: By determining if there is a relationship between strength and function it can lead the way for further research to examine strength training programs as a method of improving ambulation in an older adult. SUBJECTS: Subjects were adults 65 years or older who were recruited from Reed's Landing independent living facility and the local Springfield, MA community. METHODS: First, the subjects underwent familiarization with the Cybex NORM© isokinetic dynamometer followed by gait analysis using the Clinical Stride Analyzer©. Next, peak torque and work of the ankle musculature was measured using the isokinetic dynamometer. DATA ANALYSIS: SPSS version 17.0 statistical software program was used to perform a Pearson product correlation coefficient to determine correlations between the variables. An a posteriori regression analysis was also used to determine a difference between plantarfiexor and dorsiflexor strength to predict gait parameters. RESULTS: A strong correlation was found between gait velocity and step length (r=.92). Moderate negative correlations were identified between cadence and right dorsiflexor torque at 60°/sec (r -.58) and 120°/sec (r= -.55) and cadence and right dorsiflexor work (r= -.68). An a posteriori regression analysis did not reveal a significant difference between dorsiflexor and plantarfiexor torque in predicting cadence. CONCLUSIONS: The results did not strongly support the hypothesis of the study, which was that there would be a relationship between ankle musculature and gait parameters. It would be beneficial to perform further research on this topic to determine if a relationship does exist that may have been confounded by the limitations of this study or if other muscle groups have an impact on gait parameters in the older adult.

Book Description
Locomotion is an important and inherent part of daily life and is integral in maintaining an independent lifestyle, especially in older adults whose functional capacity has declined. Physiological changes with aging, including loss of muscle mass, strength and power are manifested in walking, notably at the ankle joint. Old adults exhibit decreased power of the plantarflexors and increased power of the hip extensors. This distal to proximal shift in function could be due to plantarflexor weakness, so strengthening the plantarflexors may help reverse the negative physiological effects of aging and help preserve functional capacity in old adults. The purpose of this study was to determine the effect of plantarflexor strength training on gait biomechanics during level walking at a self-selected, a safe maximum and a standard speed of 1.5 m/s in healthy old adults. A total of 12 healthy adults between the ages of 65 and 85 participated in this study (6 strengthening, 6 stretching). After baseline tests, the strengthening group performed resistance exercises for gastrocnemius and soleus muscles and the stretching group stretched them three times per week for 12 weeks. All subjects underwent gait assessments and maximal strength testing at the beginning and end of the 12 week training period. A 2 by 2 analysis of variance was used to determine significant interactions and main effects with an alpha level of p

Book Description
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.

Book Description
When a child has a health problem, parents want answers. But when a child has cerebral palsy, the answers don't come quickly. A diagnosis of this complex group of chronic conditions affecting movement and coordination is difficult to make and is typically delayed until the child is eighteen months old. Although the condition may be mild or severe, even general predictions about long-term prognosis seldom come before the child's second birthday. Written by a team of experts associated with the Cerebral Palsy Program at the Alfred I. duPont Hospital for Children, this authoritative resource provides parents and families with vital information that can help them cope with uncertainty. Thoroughly updated and revised to incorporate the latest medical advances, the second edition is a comprehensive guide to cerebral palsy. The book is organized into three parts. In the first, the authors describe specific patterns of involvement (hemiplegia, diplegia, quadriplegia), explain the medical and psychosocial implications of these conditions, and tell parents how to be effective advocates for their child. In the second part, the authors provide a wealth of practical advice about caregiving from nutrition to mobility. Part three features an extensive alphabetically arranged encyclopedia that defines and describes medical terms and diagnoses, medical and surgical procedures, and orthopedic and other assistive devices. Also included are lists of resources and recommended reading.
