Summary: This study aimed to assess the usefulness of the King-Devick (K\\D) test as a predictive test for prolonged concussion symptoms. The results showed that higher post-injury K\\D scores were associated with longer time to return to play (RTP), indicating the need for further investigation into the utility of the K\\D test for prognostication in a clinical setting.

Summary: The Vestibular/Ocular-Motor Screening (VOMS) is valuable for identifying acute concussion, but its utility for preseason baseline measurements remains unclear. Analyzing VOMS, SCAT3, and ImPACT showed large effect sizes for postinjury assessments, but incorporating baseline assessments did not significantly improve diagnostic yield for acute concussions. High within-patient test-retest variability was found across all tools, leading to poor reliability in identifying acute concussion in collegiate athletes.

Summary: This study found that the diagnostic accuracy of a rapid number-naming task with eye tracking, the King-Devick Eye Tracking (K-D ET) assessment, in identifying sport-related concussion (SRC) was not high. Only the completion time of the K-D ET test showed high specificity, while other oculomotor parameters did not have high sensitivity or specificity.

Summary: Virtual reality (VR) has been explored as a tool to improve assessments in sport-related concussion (SRC). This study found no significant difference in symptom provocation change score (SPCS) and near point of convergence (NPC) average score among current clinical manual VOMS, a clinical prototype, and VR. Additionally, the use of VR for testing has minimal impact on sex differences.

Summary: This study aimed to explore the differences in vestibular ocular motor screening (VOMS) symptoms between healthy adults and adults with persistent symptoms after mild traumatic brain injury (mTBI), and to investigate the relationships between VOMS symptoms and other measures. The results showed that the mTBI group had more VOMS symptoms and a further near point of convergence (NPC) distance compared to healthy controls. Self-reported symptoms on the Dizziness Handicap Inventory (DHI) were strongly associated with VOMS symptom scores. No significant relationships were found between VOMS symptoms and other measures. These findings support the relevance of VOMS for mTBI and its ability to capture vestibular complaints in this population.

Summary: Our analysis provides insights into the concussion injury rates in women's rugby codes, with rugby league having higher rates compared to rugby 15s and rugby 7s. The risk of concussion during match participation is significantly higher than during training for women's rugby 15s. The estimated costs associated with reported concussions were substantial, highlighting the importance of addressing this issue.

Summary: The study aimed to examine the concurrent validity of player self-reported and independently observed throwing volume, and to investigate the influence of sex, playing position, and time to upload self-reported data on the accuracy of self-reported throwing loads. The findings showed a moderate positive correlation between self-reported and observed throwing loads, but most players reported values with significant error. Therefore, the accuracy of self-reported throwing load needs to be re-evaluated.

Summary: This study examined the impact of blood flow restriction (BFR) during treadmill walking on gait kinematics. The results showed that BFR increased anterior trunk flexion, knee flexion during stance, and step width. Additionally, BFR resulted in higher ratings of perceived exertion and discomfort, as well as increased blood lactate concentration. These findings suggest that applying BFR during moderate and fast treadmill walking modifies gait kinematics and exacerbates exercise-related sensations and blood lactate concentration.

Summary: This systematic review with meta-analysis highlights a high prevalence and incidence rate of musculoskeletal injuries among military recruits undergoing basic training, with no significant improvement observed over the past 20 years. Longer training programs may reduce injury rates by decreasing the degree of overload experienced by recruits. However, reporting standards and consistency remain barriers to generalizability.

Summary: This study conducted a systematic review and meta-analysis to evaluate the impact of additional exercise interventions on bone health and fracture incidence in children. The results suggest that additional exercise interventions do not appear to improve DXA and pQCT measures of bone health in children. The effect on bone health in pre-school children is still unknown.

Summary: The primary objective of this study was to explore the barriers preventing clinicians from implementing ideal practice in using tools for diagnosis and monitoring of mid-portion Achilles tendinopathy. The secondary objectives were to describe the assessments used by clinicians in their own practice for diagnosis and monitoring, and to explore the outcome measure domains considered most and least important. The study identified financial and time constraints, limited access to equipment, and patient symptom severity as main barriers. The most important outcome measure domains for diagnosis were pain on loading and pain over a specified time frame, while for monitoring progress they were pain on loading, patient rating of the condition, and physical function capacity.
