ACCELERATED PLETHYSMOGRAM IN NURSING-HOME RESIDENTS

To investigate the peripheral blood circulation, 24 young volunteers, 28 nursing home residents with cerebrovascular diseases (CVD) and 42 residents without them were studied for accelerated plethysmogram (APG). Both residents were rated by the modified Stockton geriatric rating scale (modified SGRS) which have four aspects of impairments; physical disability, socially irritating behavior, communication failure and apathy. As to the waveform patterns of APG, the majority of the young volunteers and both the residents showed patterns B and G, respectively. Coefficient of APG (Co-APG) of the former was significantly larger than that of the latter. In the residents without CVD, Co-APG was significantly negatively correlated with physical disability and apathy of the modified SGRS. But, Co-APG did not correlate with the modified SGRS in the residents with CVD.
