BACKGROUND: Syncope is a common problem in the general population and results in significant societal and patient costs. Several small studies have demonstrated differences in orthostatic response, and possibly tolerance, between blacks and whites. Based on these observations, we retrospectively reviewed results from our tilt table database to identify potential differences in response to tilt-table testing with regards to race, between black and white patients. METHODS: The reports of 446 tilt-table tests performed on adults, older than 18 years of age, at Boston Medical Center, an urban, tertiary-care, academic hospital, were reviewed...

The vestibular system has both direct and indirect connections to the soleus motor pool via the vestibulospinal and reticulospinal tracts. The exact nature of how this vestibular information is integrated within the spinal cord is largely unknown. The purpose of this study was to identify whether changes in static otolithic drive altered the amount of presynaptic inhibition in the soleus H-reflex pathway. Changes in static otolithic drive were investigated in sixteen healthy participants using a tilt table...

Introduction: Tilt tables enable early mobilization of patients by providing verticalization. But there is a high risk of orthostatic hypotension provoked by verticalization, especially after neurological diseases such as spinal cord injury. Robot-assisted tilt tables might be an alternative as they add passive robotic leg exercise (PE) that can be enhanced with functional electrical stimulation (FES) to the verticalization, thus reducing the risk of orthostatic hypotension. We hypothesized that the influence of PE on the cardiovascular system during verticalization (i...

Physiological variables, such as heart rate (HR), blood pressure (BP) and respiration (RESP), are tightly regulated and coupled under healthy conditions, and a break-down in the coupling has been associated with aging and disease. We present an approach that incorporates physiological modeling within a switching linear dynamical systems (SLDS) framework to assess the various functional components of the autonomic regulation through transfer function analysis of nonstationary multivariate time series of vital signs...

Adolescents with postural orthostatic tachycardia syndrome (POTS) often have pain and functional impairment. This study evaluated how parental attributions of children's symptoms relate to child functional impairment. Adolescents with chronic pain and clinical symptoms suggestive of autonomic dysfunction (fatigue, dizziness, nausea) that attended a multidisciplinary chronic pain clinic completed measures of depression, anxiety, and functioning (n = 141). Parents of 114 of these patients completed the Parent Pain Attribution Questionnaire (PPAQ), a measure indicating the extent they believe physical and psychosocial factors account for their child's health condition...

BACKGROUND: Pelvic tilt influences acetabular orientation (AO). Anatomical AO can be measured in relation to the anterior pelvic plane (APP), functional AO can be calculated relative to table's plane. OBJECTIVE: To assess to what extent functional AO is determined by pelvic tilt and if APP and table plane give equal information for correct AO. METHODS: AO was evaluated by computed tomography (CT) scans of 138 patients. Pelvic tilt, anatomical and functional AO were measured, differences between the two reference planes were calculated...

In this study we wanted to verify the diagnostic value of tilt table test (TTT) to predict the efficacy of cardiac pacing (PM) for preventing recurrences of neurally mediated reflex syncope (NMS) in patients with cardioinhibitory activity (CI) documented by implantable loop recorder (ILR). Among patients selected by ILR in the context of severe clinical presentation of NMS, we analysed those who underwent PM implantation. In this observational and retrospective study we wanted to verify the results of TTT in the groups of treated patients with and without recurrences...

BACKGROUND: The conventional technique for sacroiliac (SI) joint injection involves aligning the anterior and posterior aspects of the SI joint under fluoroscopic guidance and then entering the SI joint in the most caudal aspect. OBJECTIVE: We wish to highlight that there is no added advantage to aligning both the anterior and posterior joint lines of the SI joint as it is time consuming, associated with additional radiation exposure, and may make the entry into the posterior SI joint technically more difficult...

Background The current standard to gradually adapt the fragile perfusion in lower extremity free flaps to an upright posture is the dangling maneuver. This type of flap training neither fits the orthostatic target load of an upright posture, nor does it assist in mobilizing the patients effectively. In this study, we quantitatively analyzed training effects of an early and full mobilization on flap perfusion. Methods A total of 15 patients with gracilis flaps for distal lower extremity reconstruction were included...

BACKGROUND: Persistent pain in shoulder and arm following post-surgical breast cancer treatment can lead to cognitive and physical deficits. Depression is also common in breast cancer survivors. Virtual reality therapy with integrative cognitive and physical rehabilitation has not been clinically trialed for this population. The novel BrightArm Duo technology improved cognition and upper extremity (UE) function for other diagnoses and has great potential to benefit individuals coping with post-surgical breast cancer pain...

OBJECTIVES: Without gravity opposing drainage, most venous diseases would not exist. Therefore, manoeuvres that assess venous function should include gravity. The aim was to "dose" gravity in subjects using static positions and dynamic angulations on a tilt-table and to assess its effects with air plethysmography (APG) and duplex ultrasound over the femoral vein. METHODS: Three groups (providing n = 11 legs each) were compared. (a) A control group, without clinical or duplex evidence of venous disease...

BACKGROUND: Orthostatic intolerance is typically thought to be sporadic and attributed to cerebral autonomic dysfunction. We sought to identify families with inherited autonomic dysfunction manifest as symptomatic orthostatic intolerance to characterize mode of inheritance and clinical features. METHODS: Sixteen families with two or more first- or second-degree relatives with autonomic dysfunction and orthostatic intolerance were enrolled. A clinical diagnosis of autonomic dysfunction defined by symptomatic orthostatic intolerance diagnosed by head-up tilt table testing was confirmed for each proband...

We propose a sympathetic baroreflex (sBR) sequence method for characterizing sBR from spontaneous beat-to-beat fluctuations of muscle sympathetic nerve activity (MSNA) and diastolic arterial pressure (DAP). The method exploits a previously defined MSNA variability quantifying the fluctuations of MSNA burst rate. The method is based on the detection of MSNA and DAP sequences characterized by the contemporaneous DAP increase and MSNA decrease or vice versa. The percentage of sBR sequences (SEQ%sBR) was taken as an indication of the degree of sBR solicitation and the average slope of the regression lines in the (DAP, MSNA) plane was taken as sBR sensitivity (sBRSSEQ) and expressed in bursts(...

BACKGROUND: Early mobility within the ICU is associated with a number of positive outcomes including reductions in ICU and hospital length of stay and better functional recovery. The exact definition of 'early' mobility is still not defined, with the actual ability to mobilise limited by a number of perceived factors. The Sara Combilizer is a combined tilt table and stretcher chair, which allows passive transfer of patients out of bed. This study aimed to assess whether the introduction of the Sara Combilizer reduced time taken to first mobilise for patients mechanically ventilated for at least five days and at risk of ICU acquired weakness...

BACKGROUND AND PURPOSE: Recent studies have shown that several nonmotor symptoms differ between Parkinson's disease (PD) and drug-induced parkinsonism (DIP). However, there have been no reports on cardiovascular autonomic function in DIP, and so this study investigated whether cardiovascular autonomic function differs between PD and DIP patients. METHODS: This study consecutively enrolled 20 DIP patients, 99 drug-naïve PD patients, and 25 age-matched healthy controls who underwent head-up tilt-table testing and 24-h ambulatory blood pressure monitoring...

OBJECTIVE: To take care of postural disorders is a major issue in Parkinson's disease (PD). We present a documented observation suggesting the existence of a biased representation of verticality in PD, resulting in a severe retropulsion and recurrent falls. A rehabilitation program aimed to modulate verticality perception dramatically improved the postural perception of the vertical, trunk posture and balance abilities, and reduced retropulsion as well as lastingly fall frequency. OBSERVATIONS: A 68 year-old patient with Parkinson's disease fall backward 3 times a day...

OBJECTIVE: Early verticalization in ICU is recommended [1] but not documented in brain-damaged people. Using a verticalization table involves risks and stresses in this context. The main objective was to determine the safety and feasibility of in-bed verticalization in neurological intensive care. Secondary objectives were to study the immediate, hemodynamic, and respiratory impacts, as well as the effects on awakening. MATERIAL/PATIENTS AND METHODS: Observational study in a neurological intensive care unit...
