Department of Physical Education and Sport, Faculty of Sport Sciences, University of Granada, Granada, Spain.
Although prolonged training with stroboscopic eyewear has demonstrated potential for enhancing visuomotor skills, the acute effects of stroboscopic stimulation are not well understood. The aim of the study was to investigate the short-term effects of stroboscopic exposure during the ball-specific phase of soccer warm-up on agility performance in preplanned and unpredictable (RA) tasks. Also, these effects were examined both in tasks involving ball dribbling and without the ball, as well as under fatigued and non-fatigued conditions.

Lin Chuang Er Bi Yan Hou Tou Jing Wai Ke Za Zhi
November 2024
Article Synopsis
- The study analyzes the acoustic features of patients with hypopharyngeal cancer who also have vocal cord dysfunction, comparing two groups based on vocal cord activity: one with dysfunction and the other with normal function.
- Significant findings show that lesions in the experimental group are more common on the inner wall of the piriform fossa, with a statistically meaningful difference, while vocal parameters like sound intensity showed no significant difference between both groups.
- Stroboscopic laryngoscopy results indicated higher rates of glottic insufficiency and asymmetric arytenoid cartilage in the experimental group, although both groups maintained normal mucosal wave patterns on the vocal cords.
Submucosal Thyroarytenoid Myectomy with Arytenoidectomy in Treating Bilateral Vocal Fold Immobility.
Laryngoscope
November 2024
Division of Otolaryngology, Department of Surgery, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin, U.S.A.
Article Synopsis
- Surgery for bilateral vocal fold immobility (BVFI) seeks to improve airway function while maintaining voice and swallowing capabilities, and current methods often result in challenging healing outcomes and granulation tissue issues.
- A case-series analysis of eight BVFI patients who underwent a new surgical technique showed successful decannulation rates and improved respiratory symptoms without negatively impacting long-term voice or swallowing functions.
- The proposed method, submucosal thyroarytenoid myomectomy with arytenoidectomy, effectively utilizes body’s natural healing processes while preserving important laryngeal structures, enhancing overall treatment effectiveness for BVFI.
Scale for the assessment of mucosal wave dynamics of the free edges during stroboscopic examination: clinical validation study and analysis of results.
Eur Arch Otorhinolaryngol
December 2024
Department of Otorhinolaryngology and Head and Neck Surgery, Hospital Vithas Arturo Soria Madrid, Calle de Arturo Soria 105, Madrid, 28043, Spain.
Introduction: Identifying the mucosal wave (MW) is essential when studying the voice; however, its characterization and perceived measurement during laryngeal stroboscopy (LS) are not well defined or standardized because of the subjectivity of its interpretation. This article proposed and validated a scale that characterized and approximated MW measurement during LS, applied it to participants divided into a healthy group and groups with free edge conditions, and identified differences between them.
Methods: This is a descriptive and clinical validation study of the "VASQ (Vertical axis, Anteroposterior axis, Symmetry and Quantity) mucosal wave score" scale based on stroboscopy images of 137 adult men and women divided into a control group and functional and organic pathology groups.

Effects of Stroboscopic Goggles on Standing Balance in the Spatiotemporal and Frequency Domains: An Exploratory Study.
J Appl Biomech
December 2024
Department of Biomedical Engineering, University of Florida, Gainesville, FL, USA.
Balance training paradigms have been shown to effectively reduce fall risk. Visual feedback is an important sensory mechanism for regulating postural control, promoting visual perturbations for balance training paradigms. Stroboscopic goggles, which oscillate from transparent to opaque, are a form of visual perturbation, but their effect on standing balance has not been assessed.

Abductor vocal cord paralysis (AVCP) is a disabling disorder that affects the voice and the quality of life of a patient, and hence, there is importance in providing a detailed knowledge of its aetiology and management. In this review article, we offer an implicational definition of AVCP and a discussion of its background, viewed as potentially affecting voice production and health. Finally, we explore modalities of diagnosis by medical history and physical examination, visualization techniques like laryngoscopy and stroboscopy, and radiographic imaging such as computed tomography (CT) and magnetic resonance imaging (MRI) scans.

Research Committee of Young Otolaryngologists of the International Federation of Otorhinolaryngological Societies (IFOS), Paris, France.
Article Synopsis
- The study aimed to assess how consistently ChatGPT-4 analyzes clinical images of common laryngological conditions and compares its performance to that of expert laryngologists.
- The results showed that while ChatGPT-4 had a mean consistency score for image interpretation of 2.46 out of 5, it accurately analyzed cases only 15% of the time and had notable errors in diagnosing vocal fold issues.
- The conclusion indicates that ChatGPT-4 is better at suggesting initial diagnoses than at accurately analyzing clinical images or recommending appropriate additional examinations and treatments.*

The Effects of Augmenting Balance Training with Stroboscopic Goggles on Postural Control in Chronic Ankle Instability Patients: A Critically Appraised Topic.
J Sport Rehabil
August 2024
University of North Carolina at Chapel Hill, Chapel Hill, NC, USA.
Article Synopsis
- - Individuals with chronic ankle instability (CAI) often use balance training to improve their stability, but traditional methods may not fully address their needs, leading to the exploration of stroboscopic goggles as an additional tool for training.
- - Research shows that using stroboscopic goggles during balance exercises can lead to statistically significant improvements in certain measures of postural control compared to standard balance training alone, although results can vary across different studies.
- - The recommendation based on the evidence suggests that incorporating stroboscopic goggles into balance training for individuals with CAI can provide better postural control outcomes, with a moderate to high level of confidence in the findings.

Laryngoscope
November 2024
Division of Laryngology, Department of Otolaryngology - Head and Neck Surgery, University of Washington School of Medicine, Seattle, Washington, U.S.A.
Introduction: The bowing index (BI) and normalized glottal gap area (NGGA) are used to quantify vocal fold morphology in ARVA; however, the influence of the distance between the flexible laryngoscope lens and the target area is not known. The goal is to test whether the endoscopic distance impacts vocal fold morphology measurements in patients with ARVA during flexible video laryngostroboscopy (VLS).
Method: Patients with ARVA who underwent VLS were included.
