Food insecurity is associated with metabolic syndrome among US adults: NHANES 2005-2016.

The primary objective of this study was to examine the association between food security status and metabolic syndrome (MetS) using a nationally representative dataset. We hypothesized that food insecurity would be associated with an increased odds of having MetS. This was a cross-sectional analysis of data from the 2005-2006 to 2015-2016 National Health and Nutrition Examination Survey data collection cycles. Food security was measured using the US Food Security Survey Module. Presence of MetS was determined using the National Cholesterol Education Program Adult Treatment Panel III criteria. The association between food insecurity and MetS was examined using logistic regression models stratified by sex and adjusted for poverty to income ratio, age, race, marital status, educational attainment, smoking status, and body mass index. After adjusting for covariates, men with marginal (odds ratio, 1.64; 95% confidence interval [CI], 1.22-2.20) and low (odds ratio, 1.33; 95% CI, 1.02-1.73) food security had a higher odds of having MetS than men with full food security; however, this association was lost among men with very low food security. For women, very low food security was associated with a 1.61 times greater odds of having MetS (95% CI, 1.16-2.25). These results suggest that food insecurity is generally associated with an increased prevalence of MetS for women, but not necessarily for men. These findings highlight the need to address rising food insecurity rates, while also highlighting the need for further research to fully elucidate the role of gender and sex in food insecurity and chronic disease.

Telehealth Evaluation in the United States: Protocol for a Scoping Review.

BACKGROUND: The rapid expansion of telehealth services, driven by the COVID-19 pandemic, necessitates systematic evaluation to guarantee the quality, effectiveness, and cost-effectiveness of telehealth services and programs in the United States. While numerous evaluation frameworks have emerged, crafted by various stakeholders, their comprehensiveness is limited, and the overall state of telehealth evaluation remains unclear. OBJECTIVE: The overarching goal of this scoping review is to create a comprehensive overview of telehealth evaluation, incorporating perspectives from multiple stakeholder categories. Specifically, we aim to (1) map the existing landscape of telehealth evaluation, (2) identify key concepts for evaluation, (3) synthesize existing evaluation frameworks, and (4) identify measurements and assessments considered in the United States. METHODS: We will conduct this scoping review in accordance with the Joanna Briggs Institute (JBI) methodology for scoping reviews and in line with the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews). This scoping review will consider documents, including reviews, reports, and white papers, published since January 1, 2019. It will focus on evaluation frameworks and associated measurements of telehealth services and programs in the US health care system, developed by telehealth stakeholders, professional organizations, and authoritative sources, excluding those developed by individual researchers, to collect data that reflect the collective expertise and consensus of experts within the respective professional group. RESULTS: The data extracted from selected documents will be synthesized using tools such as tables and figures. Visual aids like Venn diagrams will be used to illustrate the relationships between the evaluation frameworks from various sources. A narrative summary will be crafted to further describe how the results align with the review objectives, facilitating a comprehensive overview of the findings. This scoping review is expected to conclude by August 2024. CONCLUSIONS: By addressing critical gaps in telehealth evaluation, this scoping review protocol lays the foundation for a comprehensive and multistakeholder assessment of telehealth services and programs. Its findings will inform policy makers, health care providers, researchers, and other stakeholders in advancing the quality, effectiveness, and cost-effectiveness of telehealth in the US health care system.

Adherence to the healthy eating index-2010 and alternative healthy eating index-2010 in relation to metabolic syndrome among African Americans in the Jackson heart study.

OBJECTIVE: The primary objective of this study was to determine whether Healthy Eating Index (HEI) and Alternative Healthy Eating Index (AHEI) scores were associated with incident metabolic syndrome. DESIGN: This study is a secondary analysis of data from the Jackson Heart Study. HEI and AHEI scores were divided into quintiles and Cox proportional hazards regression models were analysed for 1864 African American adults free from metabolic syndrome at Exam 1 to examine the incidence of metabolic syndrome by quintile of dietary quality score. SETTING: Hinds, Madison and Rankin counties, Mississippi, USA. PARTICIPANTS: African American adults, ages 21-94 years, 60·9 % female. RESULTS: Over a mean follow-up time of 6·7 years, we observed 932 incident cases of metabolic syndrome. After adjusting for multiple covariates, a higher HEI score at Exam 1 was not associated with the risk of incident metabolic syndrome, except when looking at the trend analysis for the subgroup of adults with two metabolic syndrome components at Exam 1 (P-trend = 0·03). A higher AHEI score at Exam 1 was associated with the risk of incident metabolic syndrome (hazard ratio for those in the highest quintile compared to the lowest: 0·80 (95 % CI: 0·65, 0·99), P-trend = 0·03). CONCLUSION: These findings suggest that a dietary pattern that scores higher on the AHEI may help reduce the risk of metabolic syndrome, even for adults who already have two of the minimum of three components required for a diagnosis of metabolic syndrome.

Economic evaluation and costs of remote patient monitoring for cardiovascular disease in the United States: a systematic review.

BACKGROUND: Remote patient monitoring (RPM) has emerged as a viable and valuable care delivery method to improve chronic disease management. In light of the high prevalence and substantial economic burden of cardiovascular disease (CVD), this systematic review examines the cost and cost-effectiveness of using RPM to manage CVD in the United States. METHODS: We systematically searched databases to identify potentially relevant research. Findings were synthesized for cost and cost-effectiveness by economic study type with consideration of study perspective, intervention, clinical outcome, and time horizon. The methodological quality was assessed using the Joanna Briggs Institute Checklist for Economic Evaluations. RESULTS: Thirteen articles with fourteen studies published between 2011 and 2021 were included in the final review. Studies from the provider perspective with a narrow scope of cost components identified higher costs and similar effectiveness for the RPM group relative to the usual care group. However, studies from payer and healthcare sector perspectives indicate better clinical effectiveness of RPM relative to usual care, with two cost-utility analysis studies suggesting that RPM relative to usual care is a cost-effective tool for CVD management even at the conservative $50,000 per Quality-Adjusted Life-Year threshold. Additionally, all model-based studies revealed that RPM is cost-effective in the long run. CONCLUSIONS: Full economic evaluations identified RPM as a potentially cost-effective tool, particularly for long-term CVD management. In addition to the current literature, rigorous economic analysis with a broader perspective is needed in evaluating the value and economic sustainability of RPM.

Quick on Your Feet: Modifying the Star Excursion Balance Test with a Cognitive Motor Response Time Task.

The Star Excursion Balance Test (SEBT) is a common assessment used across clinical and research settings to test dynamic standing balance. The primary measure of this test is maximal reaching distance performed by the non-stance limb. Response time (RT) is a critical cognitive component of dynamic balance control and the faster the RT, the better the postural control and recovery from a postural perturbation. However, the measure of RT has not been done in conjunction with SEBT, especially with musculoskeletal fatigue. The purpose of this study is to examine RT during a SEBT, creating a modified SEBT (mSEBT), with a secondary goal to examine the effects of muscular fatigue on RT during SEBT. Sixteen healthy young male and female adults [age: 20 ± 1 years; height: 169.48 ± 8.2 cm; weight: 67.93 ± 12.7 kg] performed the mSEBT in five directions for three trials, after which the same was repeated with a response time task using Blazepod™ with a random stimulus. Participants then performed a low-intensity musculoskeletal fatigue task and completed the above measures again. A 2 × 2 × 3 repeated measures ANOVA was performed to test for differences in mean response time across trials, fatigue states, and leg reach as within-subjects factors. All statistical analyses were conducted in JASP at an alpha level of 0.05. RT was significantly faster over the course of testing regardless of reach leg or fatigue state (p = 0.023). Trial 3 demonstrated significantly lower RT compared to Trial 1 (p = 0.021). No significant differences were found between fatigue states or leg reach. These results indicate that response times during the mSEBT with RT is a learned skill that can improve over time. Future research should include an extended familiarization period to remove learning effects and a greater fatigue state to test for differences in RT during the mSEBT.

The Impact of Consumer Wearable Devices on Physical Activity and Adherence to Physical Activity in Patients with Cardiovascular Disease: A Systematic Review of Systematic Reviews and Meta-Analyses.

Objective: Consumer wearable devices allow physical activity to be measured objectively, which can be useful in remote cardiovascular disease management. This review aimed to summarize the effects of using wearable devices to monitor physical activity/adherence to physical activity in adults with cardiovascular disease. Methods: The review used The Cochrane Overview of Reviews Methodology. The databases searched were PubMed, EMBASE, CINAHL, Web of Science, and the Cochrane Database of Systematic Reviews, the date of the last search was October 12, 2021. Risk of bias was assessed using the AMSTAR-2® tool. Results: Of the 767 records, we identified 6 systematic reviews (SRs) and meta-analyses (MA) that met our inclusion criteria. The individual SRs did not consistently favor the use of wearables, but the MA syntheses each found significant effects, favoring wearable devices in measures, including mean steps per day and mean time spent completing moderate-to-vigorous physical activity. The MA on adherence to cardiac rehabilitation (CR) found greater adherence to CR with the use of a mobile app than with no app support. Summary: Within this review, there were SRs demonstrating no difference and reviews indicating a positive impact with the use of wearables for physical activity/adherence measures in individuals with cardiovascular conditions, with no studies demonstrating a negative impact. The six SR/MAs included had methodological flaws, which introduced potential biases. Additionally, the MAs included a small number of studies, which limits their generalizability. The protocol for this review was registered on PROSPERO, the international prospective register of systematic reviews (#CRD42021286699).

Gaze Fixation and Visual Searching Behaviors during an Immersive Virtual Reality Social Skills Training Experience for Children and Youth with Autism Spectrum Disorder: A Pilot Study.

Children and youth with Autism Spectrum Disorder (ASD) display difficulties recognizing and interacting with behavioral expressions of emotion, a deficit that makes social interaction problematic. Social skills training is foundational to the treatment of ASD, yet this intervention is costly, time-consuming, lacks objectivity, and is difficult to deliver in real-world settings. This pilot project investigated the use of an immersive virtual reality (IVR) headset to simulate real-world social interactions for children/youth with ASD. The primary objective was to describe gaze fixation and visual search behaviors during the simulated activity. Ten participants were enrolled and completed one social-skills training session in the IVR. The results demonstrate differential patterns between participants with mild, moderate, and severe ASD in the location and duration of gaze fixation as well as the patterns of visual searching. Although the results are preliminary, these differences may shed light on phenotypes within the continuum of ASD. Additionally, there may be value in quantifying gaze and visual search behaviors as an objective metric of interventional effectiveness for social-skills training therapy.

Use of Telehealth Services for Prenatal Care in Mississippi: Comparison of Pre-COVID-19 Pandemic and Pandemic Obstetric Management.

Background: The SARS-CoV-2 (COVID-19) pandemic resulted in major shifts in service delivery for patient care not involving COVID-19 illness. The preexisting telehealth infrastructure in Mississippi allowed the state to rapidly expand the scope of telehealth programs. Little research has been done to examine the use of telehealth during the COVID-19 pandemic and its impact on the delivery of care during pregnancy and outcomes associated with pregnancy. The objectives of this study are to (1) describe prenatal care practices during the height of the first wave of the COVID-19 pandemic, compared to the immediate prepandemic time period, and (2) explore maternal and birth outcomes during these time periods. Methods: This study was conducted as a retrospective historical cohort study from medical records at one Maternal Care Level IV (Regional Perinatal Health Care Center) in Mississippi and its affiliated centers. The participant cohort was inclusive of women who received prenatal care prior to a single birth delivery between May 1, 2020, and January 31, 2021. The pandemic cohort was defined through the timeframe of the included participants' end-term prenatal care, with reference to the beginning of the COVID-19 pandemic. The prepandemic cohort received a majority of their prenatal care prior to the COVID-19 pandemic. Results: There were 1,894 women included. Among them, 620 (32.77%) completed the majority of their end-term pregnancy in the pre-COVID-19 time period and 1,272 (67.23%) completed the end-term pregnancy during the pandemic. The odds ratio for patients from the pandemic cohort of scheduling telehealth visits compared to not scheduling telehealth visits is 8.19 (95% CI: 3.98, 16.86) times the odds ratio for patients from the prepandemic cohort. The pandemic exposure as well as infant's gestational age and very low birth weight (VLBW) show significant effects on the infant's living status in the univariate logistic regression. However, after controlling for the infant's gestational age and VLBW, we did not detect a significant effect of pandemic exposure. Conclusion: This study demonstrated a very small reliance of telehealth for the medical supervision of pregnant women during the COVID-19 pandemic. This is likely because of the essential physical examinations that occur in women who are considered to be at high risk for poor maternal and birth outcomes. Additional studies on the impact of COVID-19 infection on maternal and infant outcomes are also needed as there may be important risk factors not yet identified for poor maternal or birth outcomes.

Cost of remote patient monitoring for cardiovascular disease: a systematic review protocol.

OBJECTIVE: This review aims to evaluate the costs and cost-effectiveness of remote patient monitoring for cardiovascular disease in the United States. INTRODUCTION: Cardiovascular disease is a leading public health concern in the United States, resulting in a substantial economic burden. Remote patient monitoring has emerged as a viable and valuable care delivery method to improve cardiovascular disease management at home. However, there is limited systematic research of the cost and cost-effectiveness of using remote patient monitoring to manage the disease. INCLUSION CRITERIA: This review will consider all studies evaluating the cost of remote patient monitoring for cardiovascular disease management in the United States. The population of interest includes all individuals with various types of chronic cardiovascular disease in the United States. METHODS: The search strategy will locate both published and unpublished studies. Systematic searches will be completed in PubMed, Embase, Web of Science, CINAHL, Scopus, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, National Health Service Economic Evaluation Database, and the Cost-Effectiveness Analysis Registry. Two reviewers will independently screen titles and abstracts, followed by a full-text review against the inclusion criteria. Disagreements will be resolved through discussion between all study members. The JBI checklist for economic evaluations will be utilized to evaluate the methodological quality of studies. Data will be extracted using a modified version of the JBI data extraction form for economic evaluations. Reviewers will summarize studies and cost-related metrics. The Dominance Ranking Matrix will be used to synthesize full economic evaluation. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42021270621.

Sensory Organization Test Conditions Influence Postural Strategy Rather than Footwear or Workload.

BACKGROUND: Postural strategies such as ankle, hip, or combined ankle-hip strategies are used to maintain optimal postural stability, which can be influenced by the footwear type and physiological workload. PURPOSE: This paper reports previously unreported postural strategy scores during the six conditions of the sensory organization test (SOT). METHODS: Fourteen healthy males (age: 23.6 ± 1.2 years; height: 181 ± 5.3 cm; mass: 89.2 ± 14.6 kg) were tested for postural strategy adopted during SOT in three types of occupational footwear (steel-toed work boot, tactical work boot, low-top work shoe) every 30 min during a 4-h simulated occupational workload. Postural strategy scores were analyzed using repeated measures analysis of variance at 0.05 alpha level. RESULTS: Significant differences among postural strategy scores were only evident between SOT conditions, and but not between footwear type or the workload. CONCLUSIONS: Findings indicate that occupational footwear and occupational workload did not cause a significant change in reliance on postural strategies. The significant changes in postural strategy scores were due to the availability of accurate and/or conflicting sensory feedback during SOT conditions. In SOT conditions where all three types of sensory feedback was available, the ankle strategy was predominantly adopted, while more reliance on hip strategy occurred in conditions with absent or conflicting sensory feedback.

Dual Tasking during Trip Recovery and Obstacle Clearance among Young, Healthy Adults in Human Factors Research.

Trip-induced falls are extremely common in ergonomic settings. Such situations can lead to fatal or non-fatal injuries, affecting the workers' quality of life and earning capacity. Dual tasking (DT) is a leading cause of trips and ineffective obstacle clearance among workers. DT increases their attentional demand, challenging both postural control and concurrent secondary tasks. As the human brain has limited attentional processing capacity, even young, healthy adults need to prioritize duties during DT. This article aimed to analyze these secondary task types and their applications in recent trip-related studies conducted on young, healthy adults. An extensive review of the recent trip-related literature was performed to provide a condensed summary of the dual tasks used. In previous trip-related literature, distinct types of secondary tasks were used. The choice of the concurrent task must be made vigilantly depending on the occupation, environmental context, available resources, and feasibility. DT can be used as a tool to train workers on selective attention, which is a lifesaving skill in ergonomic settings, especially in the occupations of roofers, construction workers, or truck drivers. Such training can result in successful obstacle clearance and trip recovery skills, which eventually minimizes the number of falls at the workplace.

Social and Behavioral Factors Associated with BMI and Waist Circumference among Adolescents: The Jackson Heart KIDS Pilot Study.

Background: African American children and adolescents make up a disproportionately large segment of those classified as overweight and obese. The purpose of this study was to examine social and behavioral factors associated with accelerated accumulation of weight and adiposity among this group. Methods: The data for this cross-sectional study were drawn from the Jackson Heart KIDS Pilot Study - an offspring cohort study comprising 12- to 19-year-old descendants of Jackson Heart Study participants (N=212). Body mass index (BMI) and waist circumference were the outcomes of interest. Daily hassles, fruit and vegetable consumption, physical activity, television watching, parent/grandparent weight status and participant birth weight, age and sex were the independent variables included in the analyses. Results: Males and females were equally represented in the study and the mean BMI and waist circumference for adolescents in the study was 25.81±7.78 kg/m2 and 83.91 ± 19.81 cm, respectively. Fully adjusted linear regression models for the total sample produced results indicating that age, television viewing, weight control, and parental weight status were positively associated with BMI and waist circumference, respectively. Findings from sex-stratified models for BMI and waist circumference indicated that the significance of coefficients for age, television viewing, and parent/grandparent weight status varied by sex. Conclusions: Knowledge is limited about how sex or gender interact with social and behavioral factors to influence African Americans' health and additional studies are needed to specify how these factors interact to accelerate weight gain and adipose tissue accumulation over the life course.

Associations between sleep and academic performance in US adolescents: a systematic review and meta-analysis.

This systematic review and meta-analysis aim to investigate the relationship between sleep and academic performance in students enrolled in secondary education programs in the United States. The study team conducted a literature search of 4 databases-PubMed, Embase, CINAHL, and ERIC-on September 19 and repeated December 17, 2020. Studies were included if they were observational, published in a peer-reviewed, non-predatory journal, available in full-text, written in English, included adolescents enrolled in an organized academic program, took place in the US, and evaluated the effect of sleep duration and/or sleep quality on academic performance. After excluding reviews, editorials, interventions, and those targeting diagnostic groups, 14 studies met inclusion criteria. Risk of bias was assessed using the NIH Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies; 12 studies were found to be good or high quality, 2 were adequate/fair or poor quality. A meta-analysis of 11 of the included studies revealed that sleep duration (r = 0.03; 95%CI -0.027, 0.087; p = 0.087) and sleep quality (r = 0.089; 95%CI 0.027, 0.151; p = 0.005) had negligible correlations with academic performance (non-significant and significant, respectively). Inconsistencies in definitions, methods, and measures utilized to assess sleep duration, sleep quality, and academic performance constructs may offer insight into seemingly conflicting findings. Given the pivotal role sleep plays in development, future investigations utilizing validated and objective sleep and academic performance measures are needed in adolescents.

The Comparative Mental Health Responses Between Post-Musculoskeletal Injury and Post-Concussive Injury Among Collegiate Athletes: A Systematic Review.

BACKGROUND: The average annual national estimate of injuries sustained by collegiate athletes is 210,674, which encompasses both those of a musculoskeletal and a concussive nature. Although athletic injuries are sustained through physical means and produce physical symptoms, sports-related injuries may be a stressor among athletes that is related to mental health. PURPOSE: The purpose of this systematic review is to summarize existing literature describing mental health responses in collegiate athletes with a concussion compared to those with a musculoskeletal injury. STUDY DESIGN: Systematic Review. METHODS: Systematic searches of PubMed, CINAHL, Scopus, ProQuest, and SportDiscus were completed. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were utilized. Methodological quality was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Tool. Data extracted from the included articles included the study design, number of participants, type of injury, sex, age, sport participation, outcome measures, and time to return to play. RESULTS: A total of six articles were included. Peak depressive symptoms in athletes who sustain a concussion or musculoskeletal injury occur within one-week post-injury. No significant differences between the concussive and musculoskeletal groups anxiety scores were found at baseline or at each follow-up session. Athletes from both groups were found to be returning to their respective sports with anxiety scores representative of clinical anxiety. CONCLUSION: Similar trends in depressive and anxiety symptoms at various time points post-injury were observed in athletes with both musculoskeletal and concussive injuries. This study identified that athletes were returning to play before their psychological symptoms had returned to their baseline. LEVEL OF EVIDENCE: 2a.

Virtual immersive sensorimotor training (VIST) in collegiate soccer athletes: A quasi-experimental study.

A burgeoning area of innovation in sports is the use of extended realities to provide athletes with novel training environments. Evidence has demonstrated that virtual environments can be useful therapeutic tools with demonstrated positive outcomes. The purpose of this pilot investigation was to determine the effects of virtual immersive sensorimotor training intervention by quantifying 1) the training effect measured via change in performance pre-to post-intervention on the virtual reality exercises, 2) the difference in the in clinical measures of functional sensorimotor control, 3) the injury incidence rate, and 4) on-field performance during soccer competitions. Statistical analyses were used to describe differences between an experimental and a control group. Participants were recruited from the men and women's soccer teams at two universities in the United States. Participants at one university were in the experimental group (n = 78) and received virtual immersive sensorimotor training, consisting of nine novel exercises in headset virtual reality, twice each week for six weeks. Participants at the second university were in the control group (n = 52). The virtual exercises were developed with reference to the rehabilitative principles of neuroplasticity to train various neurologic processes, contributing to overall sensorimotor control. This includes vestibular, visual and oculomotor activities, cervical neuromotor control training, movement coordination, and postural/balance exercises. The results indicate significant positive training effects pre-to post-intervention in seven of the nine training exercises (p ≤ 0.005) and improvement in clinical tests of cervical neuromotor control, balance, and inspection time (p ≤ 0.009) in the experimental group compared to the control. One of the virtual training exercises was positively associated with on-field performance (p = 0.022). No differences in injury rate or overall on-field performance metrics between the experimental and control were detected. This research study provides evidence of training and positive transfer from virtual to real-world environments, supporting the use of these novel virtual exercises to improve measures of sensorimotor control in healthy soccer athletes.

Physical Activity and Pain in Youth With Sickle Cell Disease.

Study objectives were to examine the relationships between physical activity, pain, and psychological distress in youth 8 to 17 years of age with sickle cell disease. Participants were 206 youth with sickle cell disease (M = 11.73 years, 54.9% female, 99.5% African American). Caregivers and youth completed a clinical psychosocial screening battery. Results revealed frequent pain (37.6%), moderate median pain intensity, and elevated median pain interference in youth. Lower caregiver-reported physical activity was associated with worse pain outcomes. Increased anxiety was also associated with worse pain outcomes. A better understanding of the relationship between physical activity/inactivity and pain will guide multifactorial treatment interventions.

Social Determinants of Health: If You Aren't Measuring Them, You Aren't Seeing the Big Picture.

Clinicians often assume that interventions directly influence the recovery of patients with musculoskeletal impairments. In reality, other factors may influence recovery more than the direct treatment provided. The most powerful factor may be upstream effects such as economic stability, education, health and health care, neighborhood and built environment, and social and community context-commonly termed the social determinant of health (SDH). Although a single empirical pathway linking the collective impacts of the SDH to musculoskeletal health outcomes has not been established, our view is that they exert tremendous effects on physical therapy outcomes in practice and research. In this Viewpoint, the authors discuss the SDH and argue that recognizing the impact of SDHs on health behavior is vital to seeing the whole picture related to musculoskeletal recovery.

Sensorimotor training for injury prevention in collegiate soccer players: An experimental study.

OBJECTIVES: Deliver a sensorimotor training intervention; quantify the change in clinical measurements of sensorimotor control; and compare injury rate to a historical control. DESIGN: One-arm experimental pilot; Level 3. SETTING: NCAA Division II university athletic facilities. PARTICIPANTS: 75 collegiate soccer players (38 males; 37 females) were enrolled, including 30 (40%) with history of concussion, and participated in eight training sessions. OUTCOMES: Change in pre-to post-intervention for: static balance on the Sway app, near-point convergence, self-reported symptoms on the Post-Concussion Symptom Scale, cervical flexor neuromotor control/endurance, measured by the Cranial-Cervical Flexion Test and Joint Position Error test, and gaze stability on the Dynamic Visual Acuity Test. Injury incidence rate in 2018 was calculated using the number of traumatic injuries across the season and athlete exposure counts, as compared to a historical control. RESULTS: Significant improvements were obtained in static balance, cervical flexor neuromotor control/endurance, and near-point convergence (p-values<0.01-0.03). Increases in symptom report (p = 0.02) and a decline in dynamic gaze stability (p < 0.01) were observed. There were 11.8 injuries/1000 athlete exposures in 2017 and 8.9 injuries/1000 athlete exposures in 2018 after the treatment (p = 0.18). CONCLUSION: This intervention holds promise as a preventive strategy for sports-injury as a comprehensive population-based intervention.

History of concussion and risk of subsequent injury in athletes and service members: A systematic review and meta-analysis.

Risk of secondary injury after a primary concussion in sports and military contexts is an emerging area of interest in research. The purpose of this review was to provide an evidence synthesis describing risk of injury in athletic and military populations with and without a history of concussion. Electronic database searches were completed through September 7, 2018 in PubMed, EMBASE, CINAHL and SCOPUS. Peer-reviewed observational studies of any design with participants who were athletes or service members; measured the outcome of any type of injury; and compared injury between those with and without a history of concussion were included. Risk of bias was assessed using the Q-Coh II. Twenty-seven articles were included. Seventeen meta-analyses were completed for risk of any injury, risk of concussion, and risk of extremity injury using odds, hazard, and rate ratios. The results indicate significantly increased odds of all injuries (OR = 2.55; 95%CI 1.85,3.52); concussion (OR = 3.73; 95%CI 2.41,5.78); and lower extremity injuries (OR = 1.60; 95%CI 1.32,1.94) in those with a history of concussion compared to those without. Additional analyses reveal this increased risk is apparent when looking at time to event data and rate of injury based on number of exposures. While the reasons for the increased incidence of secondary injury associated with a concussion are not yet understood, there are potentially behavioral attributes and motor control deficits that contribute. It is suggested that research is needed to determine if active therapeutic treatment for disturbances in sensorimotor and neuromotor control after concussion could attenuate the increased risk for injury.

Effectiveness of kinesiology tape on sports performance abilities in athletes: A systematic review.

OBJECTIVE: Establish the effectiveness of kinesiology tape (KT) on sports performance abilities compared to that of other tapes or no tape with consideration to the application methodology, timeframe, and outcome measurement. METHODS: PubMed, Embase, and PEDro databases were systematically searched. The following inclusion criteria were applied: 1) participants were healthy athletes, 2) compared any brand of dynamic KT to other types of tape (sham or therapeutic) and/or no tape, 3) measured some construct of functional sports performance, 4) involved randomization. The PEDro scale was used to grade the risk of bias. RESULTS: Fifteen studies met the inclusion criteria with PEDro scores ranging from 3 to 8 of 10 points. The sports performance abilities included: ball skills; power squats; cycling; dynamic balance; jumping (vertical and horizontal); agility; sprint speed; and distance running with 193 comparisons between KT and other tapes or no tape at a variety of timeframes after application. In total, eleven comparisons demonstrated significant effects: 2 in favor of KT, 8 in favor of Mulligan's tape, and one in favor of no tape. CONCLUSION: There is a lack of compelling evidence to support the use of KT to enhance the sports performance abilities based on this review. LEVEL OF EVIDENCE: 1a-.
