Advance Injury Prevention Research Articles

Beyond the Boundary: A Bibliometric Analysis of the Published Research on Injuries in Cricket.

Cricket, a sport immensely popular in the Indian subcontinent and Commonwealth countries, boasts a staggering global following of over 1 billion enthusiasts. However, injuries in cricket are prevalent, resulting in detrimental effects on player performance and leading to substantial absenteeism from the game. In recent times, there has been a surge in interest on the epidemiology, biomechanics, and prevention of cricket-related injuries. To gain comprehensive insights into the existing research landscape, we present a bibliometric analysis of the published research on cricket injuries. The Web of Science database was searched using a well-defined search strategy. Original research articles looking at any aspect of injuries in cricket were included. Search results were imported into the R Bibliometrix package for analysis. Analysis of bibliometric parameters included top authors, journals, countries and keywords. Co-occurrence networks were generated and thematic mapping was performed to identify emerging research topics. 423 publications from 126 journals were included. An increasing trend in publications was noted. JW Orchard was the highest published author; Australia was the highest published country and the Journal of Science and Sport in Medicine had the highest number of publications. Fast bowlers were the most extensively researched and the major research was noted to focus on three niche areas, i.e., epidemiology, consensus definitions and spinal issues in fast bowlers. Research on batsmen, wicketkeepers and fielders was relatively sparse. Furthermore, we observed limited representation of research from the Indian subcontinent, despite cricket's immense popularity in the region. Our study findings highlight that majority of the cricket injury research stems from developed countries. The primary research areas include epidemiology, injury prevention, and biomechanics, with a particular focus on fast bowlers. However, much more has to be done to encourage research publications, focused on batsmen, wicketkeeper and fielders, as well as cricket in the developing world. These insights are essential for researchers seeking to delve into cricket-related studies and organizations aiming to advance injury prevention research in cricket.

Finite element modeling of meniscal tears using continuum damage mechanics and digital image correlation

Meniscal tears are a common, painful, and debilitating knee injury with limited treatment options. Computational models that predict meniscal tears may help advance injury prevention and repair, but first these models must be validated using experimental data. Here we simulated meniscal tears with finite element analysis using continuum damage mechanics (CDM) in a transversely isotropic hyperelastic material. Finite element models were built to recreate the coupon geometry and loading conditions of forty uniaxial tensile experiments of human meniscus that were pulled to failure either parallel or perpendicular to the preferred fiber orientation. Two damage criteria were evaluated for all experiments: von Mises stress and maximum normal Lagrange strain. After we successfully fit all models to experimental force–displacement curves (grip-to-grip), we compared model predicted strains in the tear region at ultimate tensile strength to the strains measured experimentally with digital image correlation (DIC). In general, the damage models underpredicted the strains measured in the tear region, but models using von Mises stress damage criterion had better overall predictions and more accurately simulated experimental tear patterns. For the first time, this study has used DIC to expose strengths and weaknesses of using CDM to model failure behavior in soft fibrous tissue.

How can we support best practice? A situational assessment of injury prevention practice in public health

BackgroundTo effectively impact the significant population burden of injury, we completed a situational assessment of injury prevention practice within a provincial public health system to identify system-wide priorities for capacity-building to advance injury prevention in public health.MethodsA descriptive qualitative study was used to collect data on the current practice, challenges and needs of support for injury prevention. Data was collected through semi-structured interviews (n = 20) and focus groups (n = 19). Participants included a cross-section of injury prevention practitioners and leadership from public health units reflecting different population sizes and geographic characteristics, in addition to public health researchers and experts from academia, public health and not-for-profit organizations. Thematic analysis was used to code all of the data by one reviewer, followed by a second independent reviewer who coded a random selection of interview notes. Major codes and sub codes were identified and final themes were decided through iterations of coding comparisons and categorization. Once data were analysed, we confirmed the findings with the field, in addition to participating in a prioritization exercise to surface the top three needs for support.ResultsMajor themes that were identified from the data included: current public health practice challenges; capacity and resource constraints, and; injury as a low priority area. Overall, injury prevention is a broad, complex topic that competes with other areas of public health. Best practices are challenged by system-wide factors related to resources, direction, coordination, collaboration, and emerging injury public health issues. Injury is a reportedly under prioritized and under resourced public health area of practice. Practitioners believe that increasing access to data and evidence, and improving collaboration and networking is required to promote best practice.ConclusionsThe results of this study suggest that there are several system level needs to support best practice in public health injury prevention in Ontario including reducing research to practice gaps and supporting opportunities for collaboration. Our research contributes to the literature of the complexity of public health practice, and presents several mechanisms of support to increase capacity at a system level to improve injury prevention practice, and eventually lessen the population burden of injury.

Altered Stride Length in Response to Increasing Exertion among Baseball Pitchers

Overexertion caused by increased pitch counts can evoke protective biomechanical responses signified by decreased ball velocity, such as reduced throwing arm kinematics and kinetics. Among skilled pitchers, overexertion may not always present ball velocity decrements, because compensatory throwing biomechanics aid in maintaining peak ball velocity although lowering physiologic stress. Nineteen pitchers (collegiate and elite high school), randomly crossed over to pitch two simulated games at ± 25% of their desired stride length, were recorded by an eight-camera motion capture system (240 Hz) integrated with two piezoelectric force plates (960 Hz) and a professional model radar gun. HR, self-reported exertion scores, blood glucose and lactate, salivary biomarkers, peak linear hand and fastball velocities were examined. Repeated-measures ANOVA as well as independent and pairwise t-tests examined significant differences (P ≤ 0.05). Shortened strides reduced mean pitching HR by 11.1 bpm (P < 0.001), improved recovery capacity by 5.76% (P = 0.012), and lowered salivary cortisol from baseline (P = 0.001). Physiologic stress elevated with greater strides, because salivary alpha amylase was significantly elevated from baseline (P = 0.011) with no improvements evidenced in pitching HR or recovery capacity. Linear hand and ball velocities remained equivalent between stride conditions. Stride length can affect physical exertion without disrupting ball velocity, where shortening strides can plausibly respond to competitive exertion in baseball pitchers. Current pitch count standards and radar velocity accounts have not been proven efficacious in predicting exertion in professional and collegiate baseball, where biomechanical compensations arise to maintain ball velocity. In some instances, compensatory adaptations may be pathomechanic where future research identifying injurious movement patterns can advance injury prevention in professional baseball.

Bridging the gap: Bringing together intentional and unintentional injury prevention efforts to improve health and well being

Problem: Intentional and unintentional injury prevention efforts have traditionally been independent and non-integrated. Fostering collaboration between the sub-fields would enhance work within both sub-fields and advance injury prevention work as a whole. Method: A systematic assessment of similarities and differences between the sub-fields was performed, including an examination of relevant definitions and norms, research methods and findings, key risk and resiliency factors, and prevention strategies that would promote collaboration and better advance current prevention efforts. Results/Summary: Several areas exist in which injury prevention efforts could be coordinated or ideas and practices could be cross-applied, including training of practitioners, data collection and analysis, application of tools and methodologies, examination of risk and resiliency factors, and identification of funding sources and partners. Impact on Industry: This paper delineates how intentional and unintentional injury prevention practitioners can more effectively collaborate to promote safer environments and further reduce incidence of injury. An integrated injury prevention approach could significantly impact the underlying contributors to both types of injury, allowing practitioners within both sub-fields to achieve greater outcomes through increased credibility, reduced duplication of efforts, more efficient use of resources, and unified injury prevention messages.
