Abstract The aim of this study was to investigate the acute effects prior exercise (warm‐up and stretching) on electromyographic force output mechanically elicited triceps surae reflexes. Fifty male subjects performed eight reflex experiments under each three successive conditions in one session: (1) no exercise, (2) after static stretching passive (3 min) (3) a 10‐min warm‐up run treadmill. Tendon tap right leg by means standardized hammer measured custom‐built fixture. Electromyographic...
Up to 30% of patients with end-stage heart failure experience biventricular that requires mechanical support. For these patients, only bulky extracorporeal or implantable displacement pumps the total artificial have been available date, which enables limited quality life for patients. It was our goal evaluate a method would allow use 2 centrifugal left ventricular assist devices as system.Seventeen implanted HeartWare HVAD pumps, 1 device and right device. Seventy-seven percent had...
Peak pressures and relative loads were determined under the feet of 125 children between 6 10 years age. These results compared with previously published data from 111 adults. A capacitive pressure distribution platform a resolution 2 sensors/cm was used for collection during walking. As group adults, school showed considerably lower peak all anatomical structures. Larger foot dimensions respect to body weight result in reduced by distributing ground reaction forces across larger contact...
Peak pressures and regional impulses were determined under the feet of 15 children 111 adults by means a capacitive pressure distribution platform. The measurements taken during walking running revealed insights into foot function process locomotion skill acquisition. Considerably reduced peak in infant group could be attributed to softer structure lower body-weight foot-contact area ratio. An almost three times higher relative load midfoot shows that longitudinal arch is still weak...
To investigate and compare the influence of a previous history foot ulcers on plantar pressure variables during gait patients with diabetic neuropathy. Foot may be an indicator worsening However, behavior patterns over time progression neuropathy, especially in who have clinical ulcers, is still unclear. Subjects were divided into following groups: control group, 20 subjects; neuropathy without 17 at least one healed ulcer within last year, 10 subjects. Plantar distribution was recorded...
Studies using footprint-based estimates of arch height have indicated that obesity results in a lowered medial longitudinal children. However, the potentially confounding effect body composition on indirect measures height, such as index, has not been investigated.This study assessed 12 male and female adults (mean age: 39.9 +/- 8.1 years, height: 1.724 0.101 m; weight: 95.1 13.7 kg, BMI: 31.9 3.0 kg/m(2)) bioelectrical impedance analysis to produce two-component model fat mass (FM) fat-free...
Axial flow pumps have gained increased acceptance since their first clinical use in 1998. The present report summarizes the experience with patients treated for severe cardiogenic shock time a newly developed axial pump magnetically levitated bearings. Material and methods: Incor was implanted 24 between June 2002 2003. All except one patient were men. In 16 dilative cardiomyopathy, seven ischemic restrictive cardiomypathy had been diagnosed. presented catecholamine-dependent end-stage heart...

Abstract Purpose: The use of ventricular assist devices (VADs) in patients with chronic end-stage or acute heart failure has led to improved survival. We present our experience since 1987. Subjects and Methods: Between July 1987 December 2006, 1026 VADs were implanted 970 patients. Most them men (81.9%). indications were: cardiomyopathy (n = 708), postcardiotomy 173), myocardial infarction 36), graft 45), a VAD problem 6), others 2). Mean age was 46.1 (range 3 days 78) years. In 50.5% the...
Using data from six male subjects, this study compared ground reaction force and tibial acceleration parameters for running. A bone-mounted triaxial accelerometer a platform were employed collection. Low peak values found the axial acceleration, time shift toward occurrence of first in vertical was present. The to differed significantly peak, demonstrated only moderate correlation. However, high negative correlation comparison with force. Employing multiple regression analysis, could be well...
Degradation of the somatosensory system has been implicated in postural instability and increased falls risk for older people Parkinson's disease (PD) patients. Here we demonstrate that textured insoles provide a passive intervention is an inexpensive accessible means to enhance input from plantar surface feet.20 healthy adults (controls) 20 participants with PD were recruited study. We evaluated effects manipulating information feet using insoles. Participants performed standing tests, on...
