A small electrical pressure transducer was taped over each ischial tuberosity, and each subject had a thermistor taped near one tuberosity. The subjects were instrumented in the morning and allowed to go about their normal activities for the day sitting on a 4-inch foam cushion. The subjects sat at pressures greater than 150, greater than 90, and greater than 30 mmHg for 17.6 percent, 53.5 percent, and 91.8 percent of the time, respectively. The subjects sat on the average for 10.1 min without doing a pushup with a duration greater than 1 sec and sat on the average for 29.6 min without doing a pushup with a duration greater than 5 sec. Two of the subjects sat for periods greater than 60 min for greater than 75 percent of the time (ignoring pushups less than 5 sec) and greater than 65 percent of the time ignoring pushups less than 1 sec. The average time between pushups was within the generally accepted limits to prevent ulcers--10-30 minutes. A few of the subjects had occasional long periods of uninterrupted pressure greater than what is thought to be required to produce ulcers--and did not develop them.","PeriodicalId":75645,"journal":{"name":"Bulletin of prosthetics research","volume":"10-34 ","pages":"5-11"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18273663","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}

{"title":"A technique for the display of joint movement deviations.","authors":"R W Wirta, F L Golbranson","doi":"","DOIUrl":"","url":null,"abstract":"Detection of deviations in lower-limb joint movements derived during locomotion testing may be enhanced by displaying as a function of the gait cycle the algebraic difference between actual performance and a synthetic waveform. A synthetic waveform for a joint movement may be generated by applying Fourier series coefficients derived from a statistical treatment of test data characterizing the performance of normal healthy individuals walking at various velocities. Application of waveform specifics related to velocity yields a synthetic pattern serving as the criterion at the specific velocity demonstrated by a patient. The deviations, when plotted for the gait cycle, show the manner in which the actual waveform differs from the synthetic. At any increment of the gait cycle, the magnitude of the deviation and whether it is positive or negative can be determined. A positive deviation means that an expected angular position was exceeded, while a negative deviation means that an expected angular position was not reached. Individual signatures may be identified by the shape of the deviation pattern. Detection of the presence of oscillatory components in joint movements may be enhanced. Deviation patterns, developed from joint movements monitored bilaterally, often reveal compensatory activity with regard to the relative performances of the ipsilateral and contralateral limbs. Deviation amplitudes exceeding statistically determined boundaries for the synthetic waveform (e.g., two standard deviations) at specific zones of the support or wing phases facilitate identification of dysfunction. This paper describes the technique for deriving the deviation pattern, and touches upon its potential utility in evaluating locomotory performance of patients.","PeriodicalId":75645,"journal":{"name":"Bulletin of prosthetics research","volume":"10-33 ","pages":"73-9"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18251178","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}

{"title":"A computerized device for the volumetric analysis of the residual limbs of amputees.","authors":"T W Starr","doi":"","DOIUrl":"","url":null,"abstract":"Prosthetics Research Study has developed a computerized automated system for the volumetric analysis of the residual limbs of amputees. Basically, this system utilizes the same principles as does normal, clinical fluid displacement volumetric analysis, with the addition of the following--if an object is suspended in a vertical cylinder into which water is being injected at a constant rate, then the rate of rise of the water will vary proportionally, at any point, with the cross-sectional area of the object. In this system, water is pumped into a Plexiglas cylinder of appropriate size so as to immerse a residual limb within a time frame of under ten seconds while a microcomputer records the water depth as a function of time. The rate of water depth rise is recorded for 256 levels during a measurement. These results are then analyzed comparatively, on a level-for-level basis, with similar rates generated with fluid pumped into the empty cylinder, thus generating 256 discrete cross-sectional-area parameters. These are then processed (in groups of eight) into 32 actual cross sections and displayed, graphed, or stored for purposes of comparison. Possible clinical application for this kind of device includes measurement of edema and other extremity volume changes with time, and measurement of muscle activity related to axial movements of muscle bulk.","PeriodicalId":75645,"journal":{"name":"Bulletin of prosthetics research","volume":"10-33 ","pages":"98-102"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18251182","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}
