Measurements are made in healthy aging subjects to compare alterations in the neural signal processing, muscle strength, joint stiffness, walking, and postural steadiness. Parameters of sensory-motor performance from healthy aging subjects will be used as a template against which to compare elderly patients with a history of falling or neurologic or orthopedic disease. Disorders of balance and stability are among the most sig- nificant health problems of the aging population; falls are a major cause of mortality, morbidity, immobility, and premature nursing home placement). The annual incidence of falling for persons living in the community is 30% of those over the age of 65, and 40% of those over the age of 80 (I). The \"elderly\" (persons 65 years and older) face increased risk of death from a fall; they are also more likely to suffer severe nonfatal injuries from falling than younger persons. Falls account for 87% of all fracms in the elderly. Among people age 65 years or older, approximately 9500 deaths per year are attributable to falls; the incidents in which a fall initiates or contributes to a chain of events that culminates in death is probably","PeriodicalId":297811,"journal":{"name":"Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society Volume 13: 1991","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115175100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The subjects were divided into five groups according to their fasting blood sugar levels. Bispectrum. the Fourier transform of the third order cumulant sequence of blood sugar fluctuations, was fairly uniform and not significantly different among the five groups of subjects. Thus we concluded that the changes, which we demonstrated in the last meeting, in the mode of insulin-versus-sugar feedback was not due to the change in the nonlinearity characterstics increasing with the degree of diabetes.","PeriodicalId":297811,"journal":{"name":"Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society Volume 13: 1991","volume":"29 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116420669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In biological tissues, the accurate determination of the propagation path length is very difficult due to the highly irregular shape of the tissues. The accuracy in measuring the propagation path length will patly affect the accuracy of measurement of the speed of sound in the tissues. In order to overcome this problem. a pair of miniprobe rmnsducers [I, 21 was fabricated at the tips of a variable path caliper to fix and measure the path length with 0.05(mm) in accuracy. Methods to develop the measurement of the sjmd of sound by extracting the time delay of the system are proposed. Sound speed in some materials have been measured using the proposed methods as preliminary to the measurement of sound speed in biological tissues.","PeriodicalId":297811,"journal":{"name":"Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society Volume 13: 1991","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122832317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
