Changes in body orientation with respect to space during incline walking can alter vestibular information requiring a different solution to the problem of head stabilization. Eleven young adults walked along a level walkway, and ascended and descended an inclined surface. Head, neck and trunk angular positions in space were collected. Changes in the gravitoinertial vector imposed by the inclined surface, produced concomitant changes in body segment orientation that decreased head stability during the inclined walking tasks. Head, neck and trunk segments were least stable while ascending the incline creating the greatest challenge to head stability during this task. Movement strategies reflected adjustments of head-neck and neck-trunk patterns to accommodate changes in the gravitoinertial vector and insure balance of the head over the trunk.

An external trauma, illness, or other pathological cause can harm the structure and function of the spinal cord, resulting in a significant neurological disorder known as spinal cord injury (SCI). In addition to impairing movement and sensory functions, spinal cord injury (SCI) triggers complex pathophysiological responses, with the spatial dynamics of immune cells playing a key role. The inflammatory response and subsequent healing processes following SCI are profoundly influenced by the spatial distribution and movement of immune cells.

The COVID-19 pandemic has intensified workplace violence (WPV) against healthcare workers, exposing them to unprecedented levels of aggression. Incidents of verbal abuse, threats, and physical assaults have increased, especially in high-stress environments such as emergency departments and intensive care units, exacerbating psychological challenges for healthcare staff. This commentary explores the profound impact of WPV on healthcare workers' mental health and job satisfaction.

Background: Orthodontic relapse, the undesired deviation of teeth from their corrected positions, remains a significant challenge in clinical orthodontics. Incomplete periodontal bone remodeling has been identified as a key factor in this process. Despite decades of research, currently there are no effective strategies to prevent relapse.

Background: Avascular necrosis (AVN) of the femoral head is a degenerative condition characterized by ischemic bone death, resulting in pain and impaired mobility. Core decompression, a surgical intervention, is widely performed for stage II AVN to alleviate symptoms and delay disease progression. While clinical and radiological outcomes are well-documented, the psychosocial dimensions of recovery remain underexplored.

Background: A wide range of school interventions have been launched to increase childrens' physical activity. Evaluation of the effectiveness of interventions requires suitable study designs and feasible quantitative evaluations relating to the school setting. The purpose of this study was to assess the evaluation design and methods for data collection, in order to make decisions about approaching forthcoming studies of the effectiveness of active school travel (AST) interventions.
