Prognostic Power of Foot Mobility in Identifying the Risk of Musculoskeletal Injuries: A Cross-Sectional Study of Male Volleyball Players at Different Competitive Levels.

(1) Background: The arch structure and mobility of the foot are considered injury risk factors in volleyball. However, there are limited studies presenting differences in injury prevalence and the risk of lower limb injuries in relation to the competitive level in male volleyball. Therefore, the main aim of the current study was to evaluate foot mobility (through navicular drop test) as an injury risk factor in volleyball players from different competitive levels. (2) Methods: The reliability and usefulness of navicular drop testing were initially assessed in test-retest procedures (based on a sample of eight participants and 16 feet measurements), with primary analyses conducted using foot measurements of the twelve top-level volleyball players (24 feet) and eighteen academic-level volleyball players (36 feet). The modified navicular drop test was conducted, and the feet were classified based on arch height, and injury prevalence was retrospectively assessed with a previously validated questionnaire. Chi-squared tests, receiver operating curves, and logistic regression were used as statistical methods. The navicular drop test was verified as a reliable tool by intraclass correlation coefficient (ICC) (3.1) analysis. (3) Results: There were no significant differences in injury prevalence between academic- and top-level volleyball players, though there was a significant relationship between pronated foot and injury risk independent of competitive level. Generally, for both groups, thresholds above 10 mm of the navicular drop were predictors of lower limb injuries. The risk of injury if the foot was pronated ranged from 70% (academic level) to over 90% (top-level players). However, no statistically significant effect of competitive level on the chance of injury was observed. (4) Conclusions: Our study found a high prevalence of foot injuries independently of competitive level. There was a relationship between pronation of the foot and the risk of injury. However, the risk of lower limb injury was higher in pronated top-level players. Also, a navicular drop greater than 10 mm was an excellent predictor of injuries at both competitive levels.

The diurnal and seasonal relationships of pedestrian injuries secondary to motor vehicles in young people

Introduction There remains a significant morbidity and mortality in young pedestrians hit by motor vehicles, even in the era of pedestrian crossings and speed limits. The aim of this study was to compare the incidence and injury severity of motor vehicle-related pedestrian trauma according to time of day and season in a young population, based on the supposition that injuries would be more prevalent during dusk and dawn and during autumn and winter. Methods Data were retrieved from the National Trauma Audit and Research Network (TARN) database for patients between 10 and 25 years old who had been involved as pedestrians in road traffic collisions between 2013 and 2020. The incidence of injuries, their severity (using the injury severity score (ISS)) and mortality were analysed according to the hours of daylight, darkness and season. Results The study identified a seasonal pattern, highlighting that injuries were most prevalent during autumn (34.9% of injuries). Prevalence decreased throughout the year from winter (25.4%) to spring (21.4%), to summer (18.3%). The greatest incident rate (number of incidents/hour) occurred between 1500–1630 h, correlating to school pick up times, but overall there was no significant difference in injury prevalence between hours of darkness (47.3%) and daylight (52.7%). However, a significant relationship between ISS and daylight hours was demonstrated ( p-value = 0.0124), whereby moderate injuries (ISS score: 9–15) were more likely during the day (72.7%), while severe injuries (ISS score > 15) were more likely at night (55.8%). Conclusion We identified a relationship between the time of day and the frequency and severity of pedestrian trauma in young people. In addition, particular time groupings correspond to the greatest incidents rate, suggesting that reduced visibility coupled with school pick up times play a significant role. We recommend targeted public health measures to improve road safety that focus on these high-risk times of the day.

COVID-19 return to sport: Collegiate baseball injury prevalence analysis

In the spring of 2020, the COVID-19 pandemic rapidly brought college baseball to a halt. Most college baseball players saw disruption of their training and development due to interruptions of their seasons. With these interuptions, it is necessary to examine the effects of the COVID-19 pandemic on collegiate baseball injury epidemiology. Data from a small-school Midwest collegiate conference was tallied for the number of collegiate conference injuries per year, and for the injuries per anatomic region. An unpaired t-test was conducted upon the overall conference mean injuries per year and on each anatomic region for the mean injuries per region per year. Results demonstrated no statistically significant difference between the mean injuries per season, or the mean injuries per anatomic region per year. This study showed that small-school collegiate baseball had no significant difference in injury prevalence after the COVID-19 pandemic, differing from research at the professional level.

COVID-19 Return to Sport: NFL Injury Prevalence Analysis

BackgroundSport injuries have been common among athletes across the globe for decades and have the potential to disrupt athletic careers, performance, and psyche. Many health professionals and organizations have undertaken injury mitigation strategies to prevent sport injuries through protective equipment, training protocols, and a host of other evidence-based practices. Many of these specialized training methods were disrupted due to protocols to mitigate the spread of COVID-19. This research examines the effects of the COVID-19 pandemic in relation to the prevalence of athletic injuries in the National Football League (NFL).ObjectiveDuring the COVID-19 pandemic, NFL teams and athletes across all levels of sport were reported to have reduced training in preparation for their seasons due to protocols to mitigate the spread of COVID-19. This study compares the prevalence of injury during the 2018, 2019, and 2020 NFL seasons, with the aim to determine the potential causes of the differences in injury prevalence.MethodsOfficial injury reports from each team were counted during the 17-week regular season of each year (2018, 2019, and 2020). The data were analyzed using an unpaired t test to compare the injury prevalence between each of the three seasons.ResultsThe 2018 season produced a total of 1561 injuries and a mean of 48.8 injuries per team. The 2019 season produced a total of 1897 injuries and a mean of 59.3 injuries per team, while the 2020 season produced a total of 2484 injuries and a mean of 77.6 injuries per team. An unpaired t test was performed using the data to compare the mean number of injuries per team during each of the seasons. Comparison of the 2020 season against the 2019 season showed a statistically significant difference (P<.001); comparison of the 2020 season to the 2018 season found a statistically significant difference (P<.001); and comparison between the 2019 and the 2018 seasons found a statistically significant difference (P=.03).ConclusionsAlthough the 2019 and 2018 seasons showed a statistically significant difference (P=.03), this difference is not as large when we compare the 2020 seasons versus the 2019 (P<.001) and 2018 (P<.001) seasons. The astronomical increase in injury prevalence during the 2020 season over the previous years raises the possibility that there was a reduced physiological adaptation to stress, due to the limited amount of training as a result of the closure of practice facilities in order to slow the spread of COVID-19.

Assessment of Injury History, Severity, and Medical Care for Athletes Participating in Brazilian Jiu-Jitsu

While Brazilian jiu-jitsu (BJJ) has a rate of injury similar to other combat sports, there is little information on the types of injuries sustained by BJJ athletes. The purpose of this study was to assess demographic information, participation rates, injuries, and medical care in BJJ athletes over a 12-month period. Seventy-eight athletes (75.0%) reported 136 injuries in the past year; however, medical attention was only sought for 59 (43.4%) of those injuries. No significant association was found between each demographic variable and injury prevalence. Despite the fact that a majority of BJJ athletes reported suffering an injury within the past year, slightly less than half of these injured athletes sought medical care. There was no difference in injury prevalence between belt ranks.

Prevalence of unintentional injury among left-behind children in mainland China: Evidence from epidemiological surveys.

Left-behind children have become a particular concern in mainland China, and unintentional injury among these children has attracted increasing attention. This review aims to present the prevalence of unintentional injury among left-behind children and subgroups in mainland China. A systematic literature search was conducted using four Chinese and two English databases. The included publications were cross-sectional studies in mainland China, of which the population was recruited according to inclusion and exclusion criteria. Information was collected using self-administered questionnaires. The risk of bias was estimated using the Strengthening the Reporting of Observational Studies in Epidemiology, and pooled prevalence was estimated through the DerSimonian-Laird proportion method. This review included 34 cross-sectional studies consisting 58,348 left-behind children in mainland China. Results showed that the pooled prevalence of unintentional injury was 38.24% (95% confidence interval (CI): 28.40-48.08) among left-behind children. The prevalence was higher among left-behind children (38.76%) than among non-left-behind children (27.94%), with an odds ratio of 1.65 (95% CI: 1.47-1.85). Furthermore, the prevalence of injury was higher among boys (39.12%) than among girls (28.61%), with an odds ratio of 1.58 (95% CI: 1.41-1.77). Falls had the highest prevalence of 20.79% among the types of unintentional injury. Furthermore, home was the occurrence location with the highest prevalence (16.20%). No significant difference in injury prevalence was observed among left-behind children without accompanying parents and those with single parent accompanying them. This review showed a relatively high injury prevalence among left-behind children in mainland China. Boys had a higher prevalence than girls. Falls had the highest prevalence, and home was the most common occurrence location.

Company size and differences in injury prevalence among apprentices in building and construction in Norway

An increased risk for injuries is found in small enterprises, and is especially evident for the construction industry. Our aim was to study injury risk among apprentices in different sized enterprises within different building and construction trades. The study design was a cross-sectional survey among all apprentices in a county in Western Norway, designed to assess injury involvement during the apprenticeship period. Six-hundred seventy-three (n=673) apprentices completed the questionnaire, giving a response rate of 81%. Overall the prevalence of injuries was higher among apprentices in training companies with 10–19 employees. However, trade-specific analysis for apprentices in building and electrical trades showed different patterns regarding injury risk across different company sizes, with increased risk in companies with 10–19 employees for the electrical trade and in companies with 20–49 employees in the building trade. In conclusion, when considering injury risk among young workers, nature of work and associated exposures, as well as other characteristics that may vary by size of the enterprise, should be assessed.

A source of healthcare disparity

Differences in anogenital injury resulting from rape may occur because of racial or skin color differences in adult women. It is critical to determine if these differences also are associated with differences in injury prevalence and frequency in adolescents and young adults. In a retrospective review of medical records, we examined whether Black adolescent/young adult females had different anogenital injuries as compared to White females following rape. Next, we examined whether skin color differences explained a significant amount of the racial difference in injuries. We reviewed charts of 234 female victims of rape ages 14 to 29. Overall injury prevalence was 62.8%. Race was significantly associated with frequency of injuries in several anatomical locations, with White victims having a higher frequency of injuries than Black victims. Skin color was significantly associated with injury frequency in many anatomical locations, with victims with light skin sustaining more injuries than victims with dark skin. Even when skin color was included in the relationship, race remained a statistically significant factor, suggesting that the relationship between race and injuries may be more complicated than merely a skin color difference that has been mislabeled a racial difference.

Behavioral Risk Factors and Unintentional Injuries Among U.S. Immigrant Adults

This study compared 10 risk-taking behaviors generally considered to be risk factors for injuries and unintentional nonfatal injuries between immigrant and U.S.-born adults. Data from the 2001 to 2002 National Epidemiologic Survey on Alcohol and Related Conditions were analyzed. The prevalence of unintentional injuries that occurred in the past 12 months was calculated for foreign-born and U.S.-born respondents by major sociodemographic characteristics. The proportion of respondents who were involved in risk-taking behaviors was compared between immigrants and U.S.-born adults using a chi(2) test. Negative binominal Poisson regression models were used to study the association among immigrant status, total number of risk-taking behaviors, and injuries while controlling for the confounding effects of sociodemographic variables. Of 43,093 adult respondents, 13.3% (95% confidence intervals [CI] = 12.5%-14.1%) of immigrants reported injuries compared with 19.1% (95% CI = 18.7%-19.5%) of U.S.-born respondents. Immigrants had a significantly lower risk of unintentional injuries than U.S.-born adults by most sociodemographic characteristics, but there was no statistically significant association between years of U.S. residence and injuries. Immigrants were less likely than their U.S.-born counterparts to be involved in all 10 risk-taking behaviors (p < 0.05 from chi(2) test). However, when immigrants engaged in more than four risk-taking behaviors, the difference in injury prevalence between the two groups was not statistically significant (p > 0.05). Immigrant and U.S.-born adults involved in high-risk behaviors face similar risks for unintentional injuries. Targeting risk-taking behaviors among immigrants warrants special attention in injury-control programs.

Comparison of Injury Rates between Cadets with Limb Length Inequalities and Matched Control Subjects over 1 Year of Military Training and Athletic Participation

To compare lower-limb overuse injury and low back pain incidence among cadets with and without limb length inequality (LLI) over 1 year of military training and athletic participation. A total of 1,100 cadets were screened for LLIs; 126 of 1,100 were identified to have a LLI of > 0.5 cm and were assigned a matched control cadet. Injury rates, numbers of visits to sick call, and numbers of days spent on medical excusal during a 1-year period were then compared for the 252 cadets. There was no difference in prevalence of injury between the groups and no significant differences (p > 0.05) between the groups in injury rates, visits to sick call, or number of days spent on medical excusal. These findings do not support any increased incidence of injuries in a young, healthy, athletic, military population with mild LLIs, compared with matched control subjects without LLIs, over 1 year.

The Effects of Age and Ethnicity on Physical Injury from Rape

To determine whether postmenopausal (age 50 years or older) women would sustain significantly more injury after rape than women younger than 50 and to determine the role of skin pigmentation in the observance of genital injury. Registry data from a sexual assault forensic nurse examiners program. Based on date of examination, records from women of age 50 years or older (n = 40) were matched to two other participants: a premenopausal group younger than 40 years and a perimenopausal group of 40 to 49 years. The final sample consisted of 120 subjects. Number, type, and location of injuries. A series of exact conditional logistic regression analyses indicated no significant association between age and genital, nongenital, or head injury. A significant association between race (Black versus White) and genital injury (adjusted odds ratio = 4.30, 95% confidence interval = 1.09-25.98, p = .03) indicated that Whites were more than four times as likely as Blacks to have genital injury. Although the primary hypothesis was not supported, the role of racial/ethnic differences and their association with the observance of injury need further exploration to determine whether the standard forensic examination is appropriate for all women. Health disparities may exist if women of color are less likely than others to have genital injuries identified and treated. Alternatively, skin properties may explain racial/ethnic differences in injury prevalence.
