One of the National Football League's (NFL) Head, Neck and Spine Committee's principal goals is to create a 'best practice' protocol for concussion diagnosis and management for its players. The science related to concussion diagnosis and management continues to evolve, thus the protocol has evolved contemporaneously. The Fifth International Conference on Concussion in Sport was held in Berlin in 2016, and guidelines for sports concussion diagnosis and management were revised and refined. The NFL Head, Neck and Spine Committee has synthesised the most recent empirical evidence for sports concussion diagnosis and management including the Berlin consensus statement and tailored it to the game played in the NFL...

Recent technological developments have led to the production of inexpensive, non-invasive, miniature magneto-inertial sensors, ideal for obtaining sport performance measures during training or competition. This systematic review evaluates current evidence and the future potential of their use in sport performance evaluation. Articles published in English (April 2017) were searched in Web-of-Science, Scopus, Pubmed, and Sport-Discus databases. A keyword search of titles, abstracts and keywords which included studies using accelerometers, gyroscopes and/or magnetometers to analyse sport motor-tasks performed by athletes (excluding risk of injury, physical activity, and energy expenditure) resulted in 2040 papers...

This systematic review examines the association between physical activity (PA) level and risk of falling in community-dwelling older adults. A search of PubMed, Embase, CINAHL, Sport Discus, and Web of Science was performed in January 2017. Four prospective cohort studies investigating the incidence of falls in a period of at least 12 months and its association with the level of PA in people 60-plus years old were reviewed and pooled for meta-analysis. The pooled risk ratio for being a recurrent faller (2,420 participants) was 39% higher among those who were in the lowest PA level (RR = 1...

In contrast to anterior cruciate ligament reconstruction, there is a paucity of primary studies that address the issue of return to play after anterior shoulder stabilization for glenohumeral instability. Most studies focused on clinical outcomes after anterior shoulder stabilization provide little detail on the authors' assessment protocols used in determining return to sport readiness. In fact, many issues germane to the postoperative rehabilitation process (biologic healing, motion recovery, strength recovery, and sport-specific considerations) remain poorly defined, and are not typically addressed using validated shoulder outcomes instruments...

Shoulder pain is a common musculoskeletal complaint that is difficult to treat because of the biomechanical complexity of the shoulder region, the interplay between mobility and stability, and the vital role played by the shoulder in moving, positioning, and providing stability for hand function. Despite advances in biomechanics and pain science, there is still much to learn about how impairments influence shoulder function and health. One impairment, posterior shoulder tightness (PST), is often noted in individuals with shoulder pain and consequently has generated much discussion and debate in recent years...

Despite increasing publications in disability sport, no bibliometric analysis has been conducted to evaluate the impact of these publications. We conducted a systematic search of the Web of Science Core Collection citation index on June 26, 2017 for publications published since 1980 to identify the top 50 most cited publications in disability sport. The top 50 cited publications were mainly articles and reviews published in the English language between 1993 and 2014. Most of the 148 authors who contributed to these publications were based in Europe and North America...

Introduction: Guided imagery involves the controlled visualization of detailed mental images. This integrative health technique is used for healing, health maintenance, or the treatment of specific conditions. Guided imagery is an integral part of mindfulness meditation, hypnosis, and various relaxation exercises. However, evidence to support the widespread use and dissemination of guided imagery interventions has been lacking. The purposes of this scoping review were to document the scope of health outcomes and disease processes examined by guided imagery researchers and the journal outlets where this work has been published...

An emerging area of research has identified that an increased risk of musculoskeletal injury may exist upon returning to sports after a sport-related concussion. The mechanisms underlying this recently discovered phenomenon, however, remain unknown. One theorized reason for this increased injury risk includes residual neuromuscular control deficits that remain impaired despite clinical recovery. Thus, the objectives of this review were: (1) to summarize the literature examining the relationship between concussion and risk of subsequent injury and (2) to summarize the literature for one mechanism with a theorized association with this increased injury risk, i...

Mechanical hyperalgesia defined as decreased pressure pain thresholds (PPTs) is commonly associated with pain. In this narrative review, we report the current state of the art within topographical pressure sensitivity maps. Such maps are based on multiple PPT assessments. The PPTs are assessed by an a priori defined grid with special focus on both spatial and temporal summation issues. The grid covers the muscle or the body region of interest using absolute or relative values determined from anatomical landmarks or anthropometric values...

INTRODUCTION: Women account for approximately 15% of the active duty US Army, and studies show that women may be at an increased risk of musculoskeletal injury during sport and military training. Nationally, the field of orthopedic surgery comprises 14% women, lagging behind other surgical fields. Demographics for US Military orthopedic surgeons are not readily available. Similarly, demographic data of graduating medical students entering Military Medicine are not reported. We hypothesize that a gender disparity within military orthopedics will be apparent...

Measurements of exercise-induced metabolic changes, such as oxygen consumption, carbon dioxide exhalation or lactate concentration, are important indicators for assessing the current performance level of athletes in training science. With exercise-limiting metabolic processes occurring in loaded muscles, 31 P-MRS represents a particularly powerful modality to identify and analyze corresponding training-induced alterations. Against this background, the current study aimed to analyze metabolic adaptations after an exhaustive exercise in two calf muscles (m...
