Background and Purpose Previous research suggests that patients receiving inpatient stroke rehabilitation are sedentary although there is little data to confirm this supposition within the Canadian healthcare system. The purpose of cross-sectional study was observe two weeks in a tertiary center determine patients' activity levels time.Methods Heart rate (HR) accelerometer were measured using an Actiheart monitor for seven consecutive days, 24 h/day, on second week last admission....
Background. Paired exercise and cognitive training have the potential to enhance cognition by “priming” brain upregulating neurotrophins. Methods. Two-site randomized controlled trial. Fifty-two patients >6 months poststroke with concerns about impairment trained 50 70 minutes, 3× week for 10 weeks 12-week follow-up. Participants were 1 of 2 physical interventions: Aerobic (>60% VO 2peak using <10% body weight–supported treadmill) or Activity (range movement functional tasks)....
Objectives: Our objectives were: 1) to determine whether maximal aerobic exercise increased serum neurotrophins in chronic stroke and 2) the factors that predict resting exercise-dependent levels.Methods: We investigated potential predictors of insulin-like growth factor-1 brain-derived neurotrophic factor among 35 patients. Predictors from three domains (demographic, disease burden, cardiometabolic) were entered into 4 separate stepwise linear regression models with outcome variables:...
Abstract Background Aerobic training has the potential to restore function, stimulate brain repair, and reduce inflammation in people with Multiple Sclerosis (MS). However, disability, fatigue, heat sensitivity are major barriers exercise for MS. We aimed determine feasibility of conducting vigorous harness-supported treadmill a room cooled 16 °C (10 weeks; 3times/week) examine longer-term effects on markers among those using ambulatory aids. Methods Ten participants (9 females) aged 29 74...
Stroke is a leading cause of disability and death worldwide. Care stroke patients both complex resource-intensive. Understanding this complexity crucial for improving healthcare delivery. This study aimed to model analyze the care system. Data were gathered through document review interviews with 17 professionals in city eastern Canada. The Functional Resonance Analysis Method (FRAM) was employed system, identify sources variability, propose solutions improve identified 73 interconnected...
To determine whether stroke survivors could maintain workloads during functional task practice that can reach moderate levels of cardiometabolic stress (i.e., ≥40% oxygen uptake reserve ([Formula: see text]O
Purpose: To determine the effectiveness of a community re-integration exercise initiative on function, mood, participation, and adherence for persons with moderate to severe neurological conditions (stroke, multiple sclerosis, etc.). Methods
Objective: Evaluate intensity-dependent effects of a single bout high intensity interval training (HIIT) compared to moderate constant-load exercise (MICE) on corticospinal excitability (CSE) and upper limb performance in chronic stroke. Design: Randomized cross-over trial. Setting: Research laboratory tertiary rehabilitation hospital. Participants: Convenience sample 12 stroke survivors. Outcome measures: Bilateral CSE measures intracortical inhibition facilitation, motor thresholds, evoked...
Abstract A coherent perception of spatial orientation is key in maintaining postural control. To achieve this the brain must access sensory inputs encoding both body and head position integrate them with incoming visual information. Here we isolated contribution proprioception to verticality further investigated whether changing without moving can modulate dependence—the extent which an individual relies on cues for orientation. Spatial was measured ten healthy individuals [6 female; 25–47...
To identify variables associated with rehabilitation length of stay (LOS) and prosthetic fitting success for people lower limb amputation (LLA).Retrospective analysis clinically collected cohort.Canadian inpatient hospital.Consecutive individuals LLA (N=103) admitted (mean age, 65.3±10.6y).Not applicable.Independent included the Lower Limb Amputee Measurement Scale (LLAMS), which is a 31-question tool to predict LOS items in medical, cognitive, social, physical, activities daily living,...
The purpose of this study was to establish an objective method for identifying the heart-rate threshold (HRT) in cyclists. Fifty-six male cyclists were tested on a cycle ergometer volitional fatigue. Identification HRT used increase above logarithmic regression line best fit, coupled with crossover linear fit. measures Vco(2) and blood lactate ventilatory (VT) (HLaT), respectively, as criterion validate HRT. Comparison VT HLaT showed significant associations (r = 0.98). Statistical variance...
The purpose of this case study was to profile maximal exercise and the incidence exercise-induced arterial hypoxemia (EIAH) at three different altitudes within a group competitive cyclists residing training 1,500 m. Ten male (category I or II professional road cyclists: ages, 27.7 ± 6.1; weight, 69.9 6.9 kg) participated in randomly assigned VO2max tests sea level (SL), m 3000 Arterial saturation (pulse oximetry), ventilation, power output (PO) were recorded continuously throughout test....
Moderate-intensity aerobic exercise training is an important treatment strategy to enhance functional recovery and decrease cardiometabolic risk factors after stroke. However, stroke related impairments limit access ergometer-type exercise. The aims of the current study were (1) evaluate whether our task-oriented circuit protocol (intermittent training; IFT) could be used sustain moderate-intensity workloads over a 10-week intervention period, (2) investigate its preliminary effects on...
To evaluate the safety and feasibility of performing treadmill aerobic exercise in moderate normobaric hypoxia among chronic hemiparetic stroke survivors.Observational study using convenience sampling.Research laboratory a tertiary rehabilitation hospital.Chronic survivors who could walk at least 10-m with or without assistance had no absolute contraindications to testing.Participants (three male four female) were asked complete three exposure protocols within single session. First, they...

Blood lactate appearance and clearance has been closely linked to fatigue (Grassi et al., 1996). At altitude during intense levels of exercise, there is an increase in formation, a drop pH increased rate. PURPOSE: It the purpose this study compare percent recovery, based on post-exercise (PE) blood (La), with sea level natives. METHODS: Fourteen (N = 14) subjects living training at (n 7) were matched by demographic measures. Each subject completed cycle ergometer protocol increasing workload...

Thresholds associated with exercise physiology (i.e., heart rate, lactate, ventilatory) are defined as variables showing a disproportionate rate change work increases proportionately. Unlike many identified thresholds, the threshold (HRT) has repeatedly shown increased and decreased changes continues to be controversial. PURPOSE The purpose of this study was establish an objective method for identifying HRT, show associations criterion measures. METHODS Subjects were twenty-five (N = 25)...
