Lower body negative pressure (LBNP) is a method derived from space medicine, which in recent years has been increasingly used by clinicians to assess the efficiency of the cardiovascular regulatory mechanisms. LBNP with combined tilt testing is considered as an effective form of training to prevent orthostatic intolerance. We have developed a prototype system comprising a tilt table and LBNP chamber, and tested it in the context of the feasibility of the device for assessing the pilots' efficiency. The table allows for controlled tilting in the range from -45 to +80° at the maximum change rate of 45°/s...

Objective: To analyze the amount of weight-bearing during tilt table increments, with a review of neutral and unilateral knee flexion postures. Methods: There were 17 healthy participants enrolled in this study. The subjects were tilted from 10° to 90°, and their body weight was measured at each 10° increment. In the first test, both plantar pressures, with the subjects in neutral posture, were recorded. During the second and third tests, the angle of inclination was thus recorded and increased, with the subjects in unilateral knee flexion posture; flexion was maintained at 25° by attaching a cylindrical support to the tilt table at the level of the popliteal fossa...

OBJECTIVES: The purpose of this study was to investigate the relationship between the onset of asystole and transient loss of consciousness (TLOC) in tilt-induced reflex syncope and estimate how often asystole was the principal cause of TLOC. BACKGROUND: The presence of asystole in vasovagal syncope (VVS) may prompt physicians to consider pacemaker therapy for syncope prevention, but the benefit of pacing is limited in VVS. METHODS: We evaluated electrocardiography, electroencephalography, blood pressure, and clinical findings during tilt-table tests...

Head-up tilt (HUT) has long been used to examine heart rate and blood pressure adaptation to changes in position. During such studies, incidental observations noted that some test subjects experienced total or near-total transient loss of consciousness and that, in some cases, hypotension was associated with unexpected marked bradycardia compatible with a vasovagal syncope (VVS) reaction. The first report of HUT as a clinical tool to confirm a diagnosis of suspected VVS was published in 1966, and led to the concept of using HUT as a diagnostic tool for VVS...

Swallow syncope is a rare dysautonomic syndrome characterized by temporary loss of consciousness upon swallowing solid foods or liquids, displaying primarily in individuals with an underlying structural or functional esophageal or cardiac pathology. However, the evidence also suggests that isolated vagal dysfunction or abnormal reactions of esophageal mechanoreceptors after mechanical irritation, demyelination, or trauma can potentially evoke  a cardioinhibitory response or vasodepression upon swallowing. We present a case of a 49-year-old otherwise healthy female patient who developed swallow syncope two weeks after whiplash neck injury acquired in a rear-end collision...

Rehabilitation after critical illness requires a multidisciplinary effort. Nutrition support of critically ill patients aims to correct the imbalance between protein synthesis and protein degradation to maximize strengthening and muscle mass, whereas physical and occupational therapists focus on optimizing strength and mobility through functional activity to help intensive care (ICU) patients return to their precritical illness level of function and improve quality of life. Early mobility has become the new standard of care for ICU patients...

BACKGROUND: Pelvic positioning during total hip arthroplasty (THA) affects functional position of the acetabular component. We sought to evaluate whether preoperative pelvic tilt correlated with intraoperative pelvic tilt while positioned on a traction table for direct anterior THA and furthermore to evaluate whether there was a consistent and predictable effect on pelvic tilt while positioned for surgery. METHODS: We evaluated the sagittal spinopelvic preoperative standing and supine pelvic tilt radiographic measurements as compared with intraoperative measurements of 25 patients...

BACKGROUND AND PURPOSE: Cerebrovascular reactivity (CR) is an ideal biomarker to detect cerebrovascular damage. CR can be quantified by measuring changes in cerebral blood flow velocity (CBFV) resulting from a CO2  vasodilatory stimulus, often using the breath-holding index (BHI). In this method, transcranial Doppler (TCD) ultrasound is used to measure CBFV changes in the middle cerebral artery (MCA) during a breath-hold maneuver. Despite its convenience, BHI has high variability. Changing body position may contribute to potential variability...

BACKGROUND: We compared microvascular and macrovascular blood flows of the tibia and anterior tibial artery during graded whole-body tilt. We hypothesized equal responses for bone microvascular and macrovascular blood flows during varying angles of tilt. METHODS: There were 18 volunteers who were randomly positioned in the following postures: supine, 15° head-up tilt, 6° head-up tilt, 6° head-down tilt, and 15° head-down tilt using an inversion table with reference to seated posture (baseline control)...

Postural tachycardia syndrome (POTS) is a heterogeneous clinical syndrome that has gained increasing interest over the past few decades due to its increasing prevalence and clinical impact on health-related quality of life. POTS is clinically characterized by sustained excessive tachycardia upon standing that occurs in the absence of significant orthostatic hypotension and other medical conditions and or medications, and with chronic symptoms of orthostatic intolerance. POTS represents one of the most common presentations of syncope and presyncope secondary to autonomic dysfunction in emergency rooms and in cardiology, neurology, and primary care clinics...
