DOI: 10.1016/j.ajo.2020.04.034
Abstract: PURPOSE Patients with idiopathic nystagmus syndrome often develop an abnormal head position. A horizontal face turn can be treated with the augmented Kestenbaum procedure, while patients with a chin up or chin down position can… read more here.

DOI: 10.1016/j.yexcr.2020.112463
Abstract: Artificial gravity is a potential countermeasure to attenuate effects of weightlessness during long-term spaceflight, including losses of muscle mass and function, possibly to some extent attributable to disturbed neuromuscular interaction. The 60-day AGBRESA bed-rest study… read more here.

Model-based spectral causality of cardiovascular variability interactions during head-down tilt
Sign Up to like & getrecommendations! Published in 2023 at "Physiological Measurement"
DOI: 10.1088/1361-6579/acce1f
Abstract: Objective. Cardiovascular control mechanisms are commonly studied during baroreceptor unloading induced by head-up tilt. Conversely, the effect of a baroreceptor loading induced by head-down tilt (HDT) is less studied especially when the stimulus is of… read more here.

DOI: 10.1111/anec.12511
Abstract: Heart rate variability (HRV) analysis is uncommonly undertaken in patients with atrial fibrillation (AF) due to an assumption that ventricular response is random. We sought to determine the effects of head‐up tilt (HUT), a stimulus… read more here.
