Influence of a Passive Tilt Test on the Proteomic Composition of the Blood of Healthy Humans
In order to identify changes in the blood proteome of healthy volunteers after passive tilt test carried out on day 19 of head-down bed rest, a...

Evaluating vestibular contributions to rotation and tilt perception
Vestibular perceptual thresholds provide insights into sensory function and have shown clinical and functional relevance. However, specific sensory...

Subjective visual vertical imprecision during lateral head tilt in patients with chronic dizziness
Most prior studies of the subjective visual vertical (SVV) focus on inaccuracy of subjects’ SVV responses with the head in an upright position. Here...

Nose-down saddle tilt improves gross efficiency during seated-uphill cycling
Riding uphill presents a challenge to competitive and recreational cyclists. Based on only limited evidence, some scientists have reported that...
-
Human vestibular perceptual thresholds for pitch tilt are slightly worse than for roll tilt across a range of frequencies
Vestibular perceptual thresholds measure vestibular sensory and perceptual noise by quantifying how small of a passive self-motion an individual is...

Lupus Anticoagulant Testing: Taipan Snake Venom Time with Ecarin Time as Confirmatory Test
Testing for lupus anticoagulants (LA) in the presence of therapeutic anticoagulation is largely discouraged because of the risk of false-positive and...

Horsefly reactions to black surfaces: attractiveness to male and female tabanids versus surface tilt angle and temperature
Tabanid flies (Diptera: Tabanidae) are attracted to shiny black targets, prefer warmer hosts against colder ones and generally attack them in...

Gravity-Dependent Modulation of Downbeat Nystagmus and Subjective Visual Vertical in the Roll Plane
Downbeat nystagmus (DBN) is the most common form of acquired central vestibular nystagmus. Gravity perception in patients with DBN has previously...

Influence of head-over-body and body-over-head posture on craniospinal, vascular, and abdominal pressures in an acute ovine in-vivo model
IntroductionOptimal shunt-based hydrocephalus treatments are heavily influenced by dynamic pressure behaviors between proximal and distal ends of...

Changes in trunk and head acceleration during the 6-minute walk test and its relation to falls risk for adults with multiple sclerosis
For persons with multiple sclerosis (MS), the general decline in neuromuscular function underlies diminished balance, impaired gait and consequently,...

Analysis of four methods of measuring three-dimensional pelvic tilt in the lateral decubitus position
Proper alignment of acetabular implantation is necessary for good patient outcomes and preventing complications or additional surgeries in total hip...

Reductions in body sway responses to a rhythmic support surface tilt perturbation can be caused by other mechanisms than prediction
Studies investigating balance control often use external perturbations to probe the system. These perturbations can be administered as randomized,...
