Article Abstract
Purpose: The video Head Impulse Test is routinely used to assess semicircular canal function in adults, but to date, pediatric reference values are scarce. This study aimed to explore the vestibulo-ocular reflex (VOR) in healthy children at different development stages and to compare the obtained gain values with reference to those in an adult population.
Methods: This prospective, single-center study recruited 187 children from among patients without otoneurological diseases, healthy relatives of these patients, and staff families from a tertiary hospital. Patients were divided into three groups by age: 3-6 years, 7-10 years, and 11-16 years. The vestibulo-ocular reflex was assessed by video Head Impulse Test, using a device with a high-speed infrared camera and accelerometer (EyeSeeCam; Interacoustics, Denmark).
Results: We found a lower vestibulo-ocular reflex gain of both horizontal canals in the 3-6-year-old group when compared with the other age groups. No increasing trend was found in the horizontal canals from age 7-10 years to age 11-16 years, and no differences were found by sex.
Conclusion: Gain values in the horizontal canals increased with age until children reached age 7-10 years and matched the normal values for adults.

Background: In tackle-collision sports, the tackle has the highest incidence, severity, and burden of injury. Head injuries and concussions during the tackle are a major concern within tackle-collision sports. To reduce concussion and head impact risk, evaluating optimal tackle techniques to inform tackle-related prevention strategies has been recommended.

Introduction: Military fast jet pilots face significant physical challenges, including high Gz accelerations during dynamic maneuvers. The objectives of this study were threefold: 1) to record pilot movements during real flights, 2) to quantify head and trunk movements under standardized Gz conditions and during basic fighter maneuvers (BFMs), and 3) to categorize compensatory strategies used to mitigate physical strain.
Methods: A total of 20 Eurofighter pilots (mean age: 28.
Temporal Modeling With Frozen Vision-Language Foundation Models for Parameter-Efficient Text-Video Retrieval.
IEEE Trans Neural Netw Learn Syst
September 2025
Temporal modeling plays an important role in the effective adaption of the powerful pretrained text-image foundation model into text-video retrieval. However, existing methods often rely on additional heavy trainable modules, such as transformer or BiLSTM, which are inefficient. In contrast, we avoid introducing such heavy components by leveraging frozen foundation models.

Background: Tracheal intubation can be challenging, especially in unanticipated cases, where patient positioning plays a critical role. The bed-up-head-elevated (BUHE) position may improve intubation outcomes.
Research Design And Methods: This randomized non-inferiority trial included 90 ASA I-II patients undergoing elective surgery.
