The purpose of the present study was to identify the cardiovascular response to lower body negative pressure in severely disabled patients during prolonged recumbency and to represent their deterioration using the discriminant function. Fifteen disabled patients and ten healthy volunteers entered the investigation. After 5min of supine rest for a control period, each subject underwent the LBNP test of -20mmHg during 5min. The disabled patients were categorized into two groups: H1 group whose members maintained thin blood pressure during LBNP in the range of normal subjects and H2 group who showed greater decrease than -2RMS error of the normal value. Both disabled groups demonstrated significantly higher heart rate (HR) in addition to both less stroke volume (SV) and cardiac output (CO) comparing with the normal subjects. Exposure to LBNP in the disabled patients produced reduction in SV and CO over the limit value resulting in decreased blood pressure. The compensatory increase in HR did not observed obviously in the H1 but also the HR in the H2 reduced lower than the velue at rest. Endocrine response in the disabled groups was insufficient comparing with the normal subjects. Deteriorated cardiovacular response in the disabled patients may result from both decreased total blood volume and dysfunction of baroreceptor-mediated reflex due to prolonged bedrest. Description of cardiovascular function by the discriminant function is useful for evaluating degree of the deconditioning and effects of the functional training.
