Book excerpt: INTRODUCTION/CLINICAL RELEVANCE: Athletes who participate in intercollegiate sports are subject to rigorous physical demands that predispose them to injury. The Move2Perform (M2P) protocol is a commercially available software program that was developed to predict injury based on athlete characteristics and performance in a battery of movement screens. Although one study has explored the predictive validity of the M2P protocol, relatively little research has been completed on this widely used product. The purpose of the current study was to determine if the commercially available Move2Perform software accurately categorizes athletes according to injury risk. METHODS: The study utilized a prospective cohort design. Subjects: Twenty-one soccer and 13 cross country athletes competing at a NCAA Division II institution in West Michigan. Methods/Procedures: Soccer and cross country athletes performed the Functional Movement Screen (FMS), Y-Balance Test for the Lower Quarter (YBT-LQ), and hop tests prior to the start of their respective sports seasons. Athlete characteristics and movement screen scores were then entered into the M2P software to categorize athletes into four injury risk classifications (optimal, Slight, Moderate, and Substantial). Athletic trainers tracked Sports-related injuries throughout the 2015-2016 soccer and cross country seasons and reported injury data to researchers. Statistical analysis: Fischer’s Exact Test was used for the primary comparison of injury risk classification and injury status to determine the predictive validity of the M2P protocol. Mantel-Haenszel Common Odds Ratios, sensitivity, specificity, and likelihood ratios were calculated. The alpha level used to determine significance was a=0.05. RESULTS: Injury risk classification was not significantly associated with injury status for the primary analysis (p=0.564), primary analysis by sport (soccer, p=0.531; cross country, p=1.000), or secondary analysis (p=0.704). Mantel-Haenszel Common odds rations did not achieve significance and varied from 0.250 to 1.667 between the analyses. The sensitivity of the M2P protocol ranged from 8.3% to 100%. Specificity range from 7.69% to 80%. The positive likelihood ratio ranged from 0.81 to 1.20. The negative likelihood ratio ranged from 0.00 to 3.25. DISCUSSION: The Move2Perform protocol was not accurate in identifying injury risk in this sample. The trend was toward false positive findings, prospectively categorizing Moderate or Substantial injury to individuals who did not sustain a neuro-musculoskeletal injury over the course of the season. There are many factors that contribute to injury risk, including chance. Sports medicine professional must acknowledge that extrinsic risk factors for injury and chance cannot be accounted for in a screen. Until more research is conducted to establish the predictive validity of the M2P protocol, sports medicine professionals should exercise caution when using injury risk classifications as the basis for medical decisions. CONCLUSIONS: The Move2Perform protocol is not a valid screening tool for predicting injury in NCAA Division II collegiate soccer and cross country athletes.

This book was released on 2015 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Participation in collegiate cross country has inherent injury risk. The Functional Movement Screen (FMS) has been used to identify increased relative injury risk in collegiate soccer, volleyball, and basketball athletes. Increased injury risk based on FMS performance in collegiate cross country athletes has not been studied. Purpose: The purpose of this study is to; 1.) establish a mean score using the Functional Movement Screen (FMS) in a single NCAA division II cross country program, 2.) determine if there is a significant difference in FMS scores between injured and non-injured runners, and 3.) determine if the FMS score, in addition to other established intrinsic and extrinsic injury risk factors, is predictive of injury. Design: Prospective longitudinal cohort design. Methods: A sample of 48 (17 males, 31 females) NCAA Division II cross country runners participated in this study. Their eligibility year, gender, past history of injury (PHI), average weekly running mileage, and FMS composite scores were collected. Differences between injured and non-injured FMS composite mean and median scores were analyzed using independent t-test and Mann-Whitney U test, respectively. A receiver operator characteristic (ROC) curve was plotted to determine an FMS cutpoint. Logistic regression using FMS composite score, gender, average running mileage, and previous history of injury as predictor variables was completed. Results: 15 of 48 athletes incurred a neuromusculoskeletal injury during the 2014 cross country season. Mean FMS for injured athletes (n=15) was 15.73 compared to 16.45 for non-injured athletes (n=33). This difference was not significant (p=.239). Median FMS scores were 16 for both injured and non-injured athletes (p=.499). The ROC area under curve (AUC) was not significant (AUC=.439; p=.505) and the ROC curve did not identify a viable cut score. The logistic regression final model included eligibility year, PHI, gender, and FMS composite scores. The Omnibus Test determined the model to be insignificant (p=.173); however, Hosmer-Lemeshow analysis determined the model to be of good fit (p=.075). The logistic regression showed that with the above variables included, the model was able to predict 94% of the athletes who did not sustain an injury correctly, and 40% of those who did sustain and injury correctly for an overall prediction rate of 77.1%. Limitations: Sample size, sample being from a single university’s cross country team, inability to control training of athletes, inability to control the number of competitive events run by each athlete, inability to control training outside of team training, the range of mileage the athletes run, mileage being self-reported, and other variables which could affect an athlete’s performance. Conclusions: The results of this study suggest that mean FMS score is not predictive of injury in NCAA Division II cross country athletes. Additionally; gender, year of eligibility, PHI, combined with FMS composite scores are not predictive of injury in this sample. However, this study had numerous limitations that may have impacted the significance of the study. With limited research to the FMS as part of a pre-participation physical as a means to predict injury in cross country athletes. Additionally, future studies should consider sports specific movements and/or tests that capture the physical demands of cross country running.

Available in PDF, EPUB and Kindle. Book excerpt: Total knee arthroplasty (TKA) is a frequently performed operation - in the U.S. alone, 5.2 million TKAs were performed from 2000-2010 - and partial (unicompartmental) knee arthroplasty (UKA) is another common operation that is done in younger, active individuals. Many patients require knee arthroplasty from osteoarthritis that develops after sports injuries or decades of participation in athletics. While much has been written regarding technical surgical details of arthroplasty, there is comparably little available on critical rehabilitation principles and guidelines that allow return to normal physical function, as well as recreational and sports activities. Filling this gap in the literature, this group of internationally recognized surgeons and therapists discusses all aspects of critical rehabilitation following both partial and total knee replacement, including: Advances in surgical techniques for robotic computer-navigated knee arthroplasty Effects of preoperative rehabilitation and nutrition on postoperative function Specific rehabilitation principles to avoid complications and return to daily activities Advanced physical therapy concepts to return to recreational and sports activities Objective testing to determine strength and physical function in the arthroplasty athlete Recommended guidelines for recreational and sports activities Key factors for achieving high patient satisfaction and quality of life after surgery Presenting the most up-to-date evidence and guidelines, Critical Rehabilitation for Partial and Total Knee Arthroplasty will be an invaluable resource for orthopedic surgeons, physical therapists, athletic trainers, personal trainers and all professionals caring for patients seeking to return to full activity after knee replacement.

Traditionally, for healthy individuals or athletes it focused on strength, flexibility, or cardiovascular training. Such training would normally be supervised by a personal fitness trainer or strength and conditioning (S&C) coach . This book promotes a different approach in that the aim of training is to promote athletic development (1,2). From the perspective of sustainable athletic development, training is not limited to strength, flexibility or cardiovascular domains, but also focuses on the fundamental A,B,Cs of agility, balance, and coordination as a foundation for enhanced movement literacy (3)"--Provided by publisher.

Available in PDF, EPUB and Kindle. Book excerpt: Care and support affects a large number of people: eight out of 10 people aged 65 will need some care and support in their later years; some people have impairments from birth or develop them during their working life; some 5 million people care for a friend or relative, some for more than 50 hours a week. The current system does not offer enough support until a crisis point is reached, the quality of care is variable and inconsistent, and the growing and ageing population is only going to increase the pressure. Consequently, two core principles lie at the heart of this White Paper. The first is that individuals, communities and Government should do everything possible to prevent, postpone and minimise people's need for formal care and support. The system should be built around the promotion of people's independence and well-being. The second principle is that people should be in control of their own care and support, with personal budgets and direct payments, backed by clear, comparable information and advice that will allow individuals and their carers to make the choices that are right for them. This paper sets out the principles and approach, with sections covering: strengthening support within communities; housing; better information and advice; assessment, eligibility and portability for people who use care services; carers' support; defining high-quality care; improving quality; keeping people safe; a better local care market; workforce; personalised care and support; integration and joined-up care.

Available in PDF, EPUB and Kindle. Book excerpt: Functional Testing in Human Performance offers clinicians the first-ever compilation of information on clinical and data-based functional testing for sport, exercise, and occupational settings. This unique text serves as a primary resource for accurate assessment of individuals' functional abilities in order to develop program prescriptions to enhance their performance. Functional Testing in Human Performance is a comprehensive learning tool for novices and an essential reference for advanced clinicians. The text defines the role of function in physical performance and how it can be appropriately tested. Especially helpful for novices, the text explains testing criteria, testing terms relevant to research, and selecting the most appropriate test and testing sequence. Common testing mistakes are also presented as well as pitfalls to avoid when testing. The text also includes case studies that illustrate a variety of situations--including testing for a client recovering from a lower-extremity injury, discussing preseason testing for a large group of athletes, and presenting the study of a client in an occupational setting. These cases include detailed statistical analysis and normative data, offering clinicians the opportunity to consider the application of functional testing and implementation strategies adaptable to their specific practice setting. After laying a foundation, the text progresses to detailed testing procedures for discrete physical parameters and specific regions of the body. Tests are organized from least to most complex, and each test is presented in a step-by-step manner outlining the purpose of the test, equipment needed, testing procedure and recommendations for performing the test, interpretation of results, and the data to suggest normative values, reliability, and validity for each test. This formatting facilitates quick reference to testing information for on-the-spot use, whether in the clinic, athletic training room, gym, or job site. Throughout the text, the functional tests are accompanied by photos for visual clarity. To enhance understanding, a companion DVD features live-action demonstrations of 40 of the most advanced tests. Icons on those test pages indicate they are modeled on the DVD. In addition, the DVD may be loaded onto a computer to offer convenient print-on-demand access to reproducible forms for recording data from selected tests. Functional Testing in Human Performance offers a unique and comprehensive reference for assessment of physical activities in sport, recreation, work, and daily living. By presenting the theory and detailing the practice, this text assists clinicians in understanding and incorporating functional testing to identify their patients' or clients' limitations and enhance their performance, rehabilitation, and daily functioning.

This book was released on 2003-05-15 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The essential nature of learning is primarily thought of as a verbal process or function, but this notion conveys that pre-linguistic infants do not learn. Far from being "blank slates" that passively absorb environmental stimuli, infants are active learners who perceptually engage their environments and extract information from them before language is available. The ecological approach to perceiving-defined as "a theory about perceiving by active creatures who look and listen and move around"-was spearheaded by Eleanor and James Gibson in the 1950s and culminated in James Gibson's last book in 1979. Until now, no comprehensive theoretical statement of ecological development has been published since Eleanor Gibson's Principles of Perceptual Learning and Development (1969). In An Ecological Approach to Perceptual Learning and Development, distinguished experimental psychologists Eleanor J. Gibson and Anne D. Pick provide a unique theoretical framework for the ecological approach to understanding perceptual learning and development. Perception, in accordance with James Gibson's views, entails a reciprocal relationship between a person and his or her environment: The environment provides resources and opportunities for the person, and the person gets information from and acts on the environment. The concept of affordance is central to this idea; the person acts on what the environment affords, as it is appropriate. This extraordinary volume covers the development of perception in detail from birth through toddlerhood, beginning with the development of communication, going on to perceiving and acting on objects, and then to locomotion. It is more than a presentation of facts about perception as it develops. It outlines the ecological approach and shows how it underlies "higher" cognitive processes, such as concept formation, as well as discovery of the basic affordances of the environment. This impressive work should serve as the capstone for Eleanor J. Gibson's distinguished career as a developmental and experimental psychologist.
