Background: Low back pain (LBP) is a common musculoskeletal disorder, and respiratory exercise is considered a nonsurgical management method. Therefore, this systematic review and meta-analysis aims to estimate the results of randomized controlled trials on the effect of respiratory training in reducing LBP and its dose relationship. Methods: The present study was conducted from January 2020 to January 2022, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (2020). Relevant studies were searched in multiple databases including PubMed, Web of Science, the Cochrane Library, EBSCO, Scopus, ScienceDirect, Wan Fang and China Knowledge Network, ClinicalTrials.gov, and Google Scholar, using a combination of MeSH/Emtree terms and free-text words. The heterogeneity of the studies was assessed using the I 2 statistic. Results: A total of 14 publications were included in the meta-analysis, with a total sample size of 698 individuals, aged 60–80 years. Respiratory exercise was effective in relieving LBP (standardized mean difference = −0.87, P < .00001) and improving physical disability (standardized mean difference = −0.79, P < .00001). The type of breathing and the total duration of breathing exercises were found to be the source of heterogeneity in this study by subgroup analysis. Subgroup analysis revealed that the most significant effect sizes of breathing resistance exercise to reduce LBP and the most significant effect sizes of breathing relaxation techniques to alleviate physical disability were performed 3 to 5 times per week and period >4 weeks. Respiratory exercise reducing LBP and improving functional disability was most effective when the total duration of the intervention was >500 minutes. Funnel plots showed that the results of the 2 overall studies were reliable without publication bias. Conclusions: Respiratory exercise can effectively reduce LBP and improve physical disability. Therefore, these exercises can be regarded as a part of a LBP management plan. We recommend an exercise program with 30 to 50 minutes, 3 to 5 times per week, and >4 weeks of breathing resistance exercise program as the most effective for treating LBP.

The Influence of Race on Time to Symptom Resolution Following Sport Concussion in Collegiate Athletes
Angelina M. Domena, Daniel J. Rosenblum, Catherine C. Donahue, and Jacob E. Resch
Context: Race has been shown to influence computerized neurocognitive test scores, motor function test scores, and reported symptomology following sport-related concussion (SRC). However, the effect race may have on recovery time following SRC remains unknown. The objective of this study was to determine the influence of race on days until symptom free from SRC in NCAA Division 1 collegiate athletes. Design: Prospective cohort study. Methods: Participants were Black (n = 53 [28% female]) and White (n = 150 [43.3% female]) who were on average 19.0 (1.21) and 20.2 (1.3) years of age, respectively. Data were collected from the 2015–2016 to 2020–2021 collegiate sport seasons. Participants were evaluated before and after an SRC at empirically derived time points. The primary outcome measure was time until symptom free (days). Additional outcomes included baseline and postinjury Immediate Postconcussion Assessment and Cognitive Test and Sensory Organization Test (SOT) scores. A Mann–Whitney U test compared days to symptom free between groups. Immediate Postconcussion Assessment and Cognitive Test and SOT outcome scores were analyzed using a 2 (group) × 2 (time) analysis of variance. Results: White participants had a longer median recovery time (9 d) to symptom free compared with Black participants (6 d [P = .04]). Statistically significant differences were observed between Black 87.3 (9.84) and White 90.4 (8.30) groups for Immediate Postconcussion Assessment and Cognitive Test’s verbal memory composite score (P = .03). Postinjury, White participants scored significantly higher 44.5 (5.63) on visual motor speed compared with Black participants (42.4 (5.90) [P = .02]). Within-group SOT differences between baseline and postinjury testing were observed in both groups (all P < .001). Conclusions: Black collegiate athletes achieved symptom resolution sooner than White athletes. We did not explore underlying sociocultural factors such as socioeconomic status or previous concussion education, which may have influenced our results. Future studies should explore factors that may contextualize these findings.
Preventing Suicide and Promoting Mental Health Among Student-Athletes From Diverse Backgrounds
Karrie L. Hamstra-Wright, John E. Coumbe-Lilley, and Eduardo E. Bustamante
Suicide and contributing mental health conditions in athletes are shared concerns within health care and society at large. This commentary focuses on suicide risk among athletes and the role of sports medicine professionals in preventing suicide and promoting mental health. In this commentary, we draw on the scientific literature and our clinical experiences to pose and answer these questions: Does suicide risk among athletes vary by sociodemographic factors (eg, sex, gender, race/ethnicity, family income, sexual orientation) or if injured? Do sociodemographic differences influence access to and benefits from services among athletes? How do I know my athletes are at risk for suicide? What do I do if one of my athletes shares with me that they have considered suicide? Within our commentary, we review the current literature and clinical practices regarding these questions and close with actionable suggestions and recommendations for future directions.

Digital Health Literacy and Social Determinants of Health Affecting Telehealth Use by Athletic Trainers
Sujal R. Patel, Nancy A. Uriegas, Tara A. Armstrong, Ryan M. Stover, Kenneth E. Games, and Zachary K. Winkelmann
Context: While increasing telehealth use throughout sports medicine has improved patients’ access to health care, some communities may not have the same opportunities to connect with a provider. Barriers to telehealth implementation can be influenced by internal (eg, provider’s digital health literacy and resources) and external (eg, community’s social determinants of health or “SDOH”) factors. This study aimed to assess the impact of internal and external factors on telehealth use by athletic trainers (ATs). Design: Cross-sectional survey. Methods: In total, 767 ATs participated in the study. Participants (age = 39 [13] y) completed a survey containing the electronic health literacy scale and digital health literacy instrument, reported professional use of telehealth as a provider (yes/no), provided resources at their clinical site, and provided the zip code for the community they served. After data collection, the researchers extracted SDOH information using the zip code data from 2 US databases, including population density, median household income, poverty index, education level, and technology access. Chi-square or independent samples t tests were conducted to compare telehealth use by each SDOH factor. Results: In total, 62.3% (n = 478/767) of ATs reported using telehealth, and 81.6% of ATs (n = 626) had a dedicated facility to offer health care services. We identified a significant difference in digital health literacy scores between users and nonusers of telehealth (P = .013). We did not identify any significant differences between telehealth users by community type (P = .957), population density (P = .053), income (P = .462), poverty index (P = .073), and computer (P = .211) or broadband internet access (P = .295). Conclusions: Our data suggest that internal factors such as digital health literacy and clinical site resources may have contributed to an AT’s previous telehealth use in clinical practice. However, the SDOH data extracted from the community zip code where the AT provided clinical services were similar for those with and without previous telehealth use.
Effect of Hearing Status on Concussion Knowledge and Attitudes of Collegiate Athletes
Matthew P. Brancaleone, René R. Shingles, and Zachary A. Weber
Context: Collegiate athletes who are deaf or hard-of-hearing (D/HoH) are diagnosed with concussions at a similar rate as athletes who are hearing; however, little evidence exists on knowledge and attitudes of athletes who are D/HoH toward concussions. This study aimed to examine differences in knowledge of and attitudes toward concussions between athletes who are D/HoH and athletes who are hearing. Design: Cross-sectional research design. Methods: Of the 310 athletes who are D/HoH and 430 athletes who are hearing that were invited to participate, 90 athletes who are D/HoH, and 72 athletes who are hearing completed the survey. The Rosenbaum Concussion Knowledge and Attitudes Survey was used to quantify knowledge of and attitude toward concussions. The Rosenbaum Concussion Knowledge and Attitudes Survey consists of the concussion knowledge index (CKI) and the concussion attitudes index (CAI) subscales. Linear regressions were run to test the association of hearing status with CKI and CAI scores. Pearson correlations were performed to determine relationships between CKI and CAI for athletes who are D/HoH and athletes who are hearing. Alpha level was set a priori at P ≤ .05. Results: Athletes who are hearing demonstrated a higher CKI component score (19.58 [2.19]) compared to athletes who are D/HoH (16.14 [3.31]; P < .001). There were no statistical differences in CAI between hearing groups (hearing: 57.18 [8.73], D/HoH: 55.97 [9.92]; P = .41). There was a moderate positive correlation between CKI and CAI (r = .58) for athletes who are D/HoH, while a weak positive correlation (r = .30) for athletes who are hearing was observed. Conclusions: Athletes who are D/HoH have poorer knowledge of concussions but similar attitudes toward concussion as that of athletes who are hearing. Current concussion educational interventions are in written or spoken form which may not be inclusive to athletes who are D/HoH. Health care professionals should consider an athlete’s preferred communication mode to improve the efficiency and effectiveness of education.

Transient Ischemic Attack in a 22-Year-Old NCAA Division I Baseball Athlete: A Case Study
Daisy Luera, Ronald L. Snarr, Sara Posson, Ioannis Liras, George Liras, and Erica M. Filep
Context: A healthy, 22-year-old, male NCAA Division I baseball shortstop was experiencing confusion, chest pain, and tightness during an off-season intersquad scrimmage. The patient did not have any significant medical history or mechanism of head injury. After initial evaluation from the athletic trainer, the patient’s cognitive status began to quickly decline. The emergency action plan was put in place rapidly and referred the patient to the local emergency clinic. Case Presentation: Upon arrival at the emergency department, an electrocardiogram was performed to rule out myocardial infarction or stroke. The first electrocardiogram results returned negative for any cardiac pathology, but a stroke alert was called. The patient was then transported to a level II trauma center due to continual cognitive decline. The patient was diagnosed with transient ischemic attack (TIA) secondary to an undiagnosed patent foramen ovale (PFO) that would later be diagnosed with further evaluation 2 months after the initial TIA incident. After multiple diagnostic and laboratory tests, the PFO went undetected until a 2D echocardiogram was performed and evaluated by a cardiologist. Management and Outcomes: After the confirmation of the congenital defect, surgical intervention was performed to correct the PFO using catheterization. Despite multiple preparticipation examinations, electrocardiograms, and examination of past family history, the PFO went undetected until the patient experienced symptoms of TIA. The discovery of PFO in this 22-year-old athletic individual is unusual because traditional screening techniques (electrocardiogram and preparticipation examinations) failed to detect the congenital defect. Conclusions: Due to the emergent and timely actions of the athletic trainer, the patient has made a full recovery and is able to compete fully in athletic events. This case study amplifies the need for athletic trainers at all sporting events, updated and reviewed emergency action plans, rapid recognition of TIA in athletic individuals, and return-to-play protocol for an athletic individual after TIA.
Pulsed Red and Blue Photobiomodulation for the Treatment of Thigh Contusions and Soft Tissue Injury: A Randomized Controlled Trial
Aaron Wells, Justin Rigby, Chris Castel, and Dawn Castel
Context: Contusion and soft tissue injuries are common in sports. Photobiomodultion, light and laser therapy, is an effective aid to increase healing rates and improve function after various injury mechanisms. However, it is unclear how well photobiomodulation improves function after a contusion soft tissue injury. This study aimed to determine the effects of a pulsed red and blue photobiomodulation light patch on muscle function following a human thigh contusion injury. Design: Single-blinded randomized control trial design. Methods: We enrolled 46 healthy participants. Participants completed 5 visits on consecutive days. On the first visit, participants completed a baseline isokinetic quadriceps strength testing protocol at 60°/s and 180°/s. On the second visit, participants were struck in the rectus femoris of the anterior thigh with a tennis ball from a serving machine. Immediately following, participants were treated for 30 minutes with an active or placebo photobiomodulation patch (CareWear light patch system, CareWear Corp). Following the treatment, participants completed the same isokinetic quadriceps strength testing protocol. Participants completed the treatment and isokinetic quadriceps strength test during the following daily visits. We normalized the data by calculating the percent change from baseline. We used a mixed model analysis of covariance, with sex as a covariate, to determine the difference between treatment groups throughout the acute recovery process. Results: We found the active photobiomodulation treatment significantly increased over the placebo group, quadriceps peak torque during the 180°/s test (P = .030), and average power during both the 60°/s (P = .041) and 180°/s (P ≤ .001) assessments. The mean peak torque and average power of 180°/s, at day 4, exceeded the baseline levels by 8.9% and 16.8%, respectively. Conclusions: The red and blue photobiomodulation light patch improved muscle strength and power during the acute healing phase of a human thigh contusion injury model.
