Forward head posture has long since been associated with a number of clinical problems treated by the fields of physical therapy and dentistry. The consistent and longstanding difficulty in the diagnosis and treatment of these conditions has been a lack of a clear understanding of the anatomical and biomechanical conditions that underly forward head posture. It has been reported that there is a narrowing of the cervical interspaces in forward head posture with the greatest change being between C4-5 and C5-6. These observations were made by viewing lateral radiographic films, yet the size of the foramina can only be viewed using oblique views. This study used oblique radiographic views of the intervertebral foramina to determine if there is a difference in the size of the intervertebral foramina in the forward head posture versus the normal head posture. The intervertebral foramina of the cervical vertebra were found to be larger in the forward head posture from levels C3 to T1. These results conflict with previous observations, suggesting that additional research is needed to assist in determining the underlying mechanisms responsible for the pain associated with forward head posture.

Multicenter randomized double-blind placebo-controlled crossover study of the effect of prolonged noisy galvanic vestibular stimulation on posture or gait in vestibulopathy.
PLoS One
January 2025
Department of Otolaryngology and Head and Neck Surgery, Graduate School of Medicine, The University of Tokyo, Bunkyo-ku, Tokyo, Japan.
Objective: This multicenter, randomized, double-blind, placebo-controlled, crossover trial aimed to evaluate whether prolonged noisy galvanic vestibular stimulation improves body balance in patients with vestibulopathy.
Materials And Methods: This trial was registered in the Japan Pharmaceutical Information Center Clinical Trials Information registry (jRCT1080224083). Subjects were 20- to 85-year-old patients who had been unsteady for more than one year and whose symptoms had persisted despite more than six months of rehabilitation.
Pedestrian POSE estimation using multi-branched deep learning pose net.

In human activity-recognition scenarios, including head and entire body pose and orientations, recognizing the pose and direction of a pedestrian is considered a complex problem. A person may be traveling in one sideway while focusing his attention on another side. It is occasionally desirable to analyze such orientation estimates using computer-vision tools for automated analysis of pedestrian behavior and intention.

PLoS One

Department of Otolaryngology-Head and Neck Surgery, Icahn School of Medicine at Mount Sinai, New York, NY, United States of America.
Objective: What we hear may influence postural control, particularly in people with vestibular hypofunction. Would hearing a moving subway destabilize people similarly to seeing the train move? We investigated how people with unilateral vestibular hypofunction and healthy controls incorporated broadband and real-recorded sounds with visual load for balance in an immersive contextual scene.
Design: Participants stood on foam placed on a force-platform, wore the HTC Vive headset, and observed an immersive subway environment.
Neurophysiological and Cognitive Changes Induced by the Acute Head-Down Tilt.
Aerosp Med Hum Perform
January 2025
Introduction: In space, under weightlessness conditions, human brain activity is changed due to the shifting of body fluid and blood toward the cephalic region. This shifting leads to changes in cerebral hemodynamics and, consequently, neurophysiological function, which impacts mental functions like cognition and decision-making capabilities of space travelers. The present study reports the effect of acute exposure to simulated microgravity on cognitive functions and event-related potentials.

Introduction: Cervical dystonia (CD) is characterized by involuntary neck muscle spasms that lead to abnormal head movements or postures. It is associated with somatosensory (tactile and proprioceptive) dysfunction. Here we tested whether vibro-tactile stimulation (VTS) of the cervical muscles constitutes a non-invasive form of neuromodulation of the somatosensory system that can provide temporary symptom relief for people with CD.
