OBJECTIVE To investigate the determinants of limb preference for initiating compensatory stepping poststroke. DESIGN Retrospective chart review. SETTING Inpatient rehabilitation. PARTICIPANTS Convenience sample of individuals admitted to inpatient rehabilitation with poststroke hemiparesis. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES(More)
BACKGROUND Extremely rapid movements are frequently executed in response to novel, potentially threatening stimuli. The mechanism by which these sophisticated responses are generated is a topic of debate. The current study investigates: 1) the importance of stimulus-response congruence in rapid responses and 2) the relationship between the autonomic nervous(More)
Impaired postural control and a high incidence of falls are commonly observed following stroke. Compensatory stepping responses are critical to reactive balance control. We hypothesize that, following a stroke, individuals with unilateral limb dyscontrol will be faced with the unique challenge of controlling such rapid stepping reactions that may eventually(More)
BACKGROUND Compensatory stepping responses are frequently observed following postural perturbations. Compensatory steps require extremely rapid onset timing while maintaining sophisticated control of limb placement. However, the influence of asymmetric limb loading on compensatory stepping limb preference and step characteristics is unknown. The purpose of(More)
Rapid reach-to-grasp (RTG) reactions are important for balance recovery. Despite the benefit of having hands free to regain balance, people do not always release a handheld object. We investigated whether reluctance to release is related to central nervous system (CNS) processing delays that occur when the initial reaction is to drop the object rather than(More)
The purpose of this research was to determine the effect of bumetanide on the volume density (Vv) of the cells, capillaries and intercellular spaces of the stria vascularis (SV). 29 chinchillas were divided into seven groups. There were 3 experimental groups, three control groups and one normal, untreated, group of animals. After either a 20 mg/kg(More)
BACKGROUND Although balance deficits are increasingly recognized in COPD, little is known regarding the disordered subcomponents underlying the control of balance. We aimed to determine the specific components of balance that are impaired in COPD and to investigate the association among balance, peripheral muscle strength, and physical activity. METHODS(More)
BACKGROUND AND PURPOSE Compensatory stepping reactions are important responses to prevent a fall following a postural perturbation. People with hemiparesis following a stroke show delayed initiation and execution of stepping reactions and often are found to be unable to initiate these steps with the more-affected limb. This case report describes a targeted(More)
BACKGROUND Individuals with stroke are at increased risk for falls soon after hospital discharge. The ability to react to a balance perturbation, specifically with a rapid step, is critical to maintain balance and prevent falls. OBJECTIVE The purpose of the study was to determine the prevalence of impaired reactive stepping responses in an ambulatory(More)
BACKGROUND Although reaction time is commonly used as an indicator of central nervous system integrity, little is currently understood about the mechanisms that determine processing time. In the current study, we are interested in determining the differences in electrophysiological events associated with significant changes in reaction time that could be(More)
