Postural performance is often characterized using center of pressure, but force distribution under the feet may provide additional information on the state of the postural control system. Foot position and orientation can also be extracted from force distribution without the need for manually tracing footprints. A low-cost force distribution measurement system is being developed to complement an existing dual force-plate platform. The system's sensing module contains 1024 1-cm by 1-cm force sensing resistors (FSRs). Interface electronics were designed to convert the FSR outputs to digital data. Continuously sampling the FSR outputs allows one to monitor force distribution over time. A system controller mediates the data acquisition process and transfers the result to a PC for post processing. An apparatus was developed to calibrate the FSRs in order to reduce error caused by inter-sensor variability. Although the system is still under development, preliminary tests show that the system can quantitatively measure force distribution beneath the feet.","PeriodicalId":294120,"journal":{"name":"Proceedings of the 1996 Fifteenth Southern Biomedical Engineering Conference","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131275048","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}

This apparently simple motor task, relies on a complex interaction of sensory and motor mechanisms. Patients with impaired input from proprioceptors and cutaneous receptors may experience difficulty with timing and scaling motor recruitment during manipulative manoeuvres. To help evaluate and retrain motor control of the hand, an instrumented pinching device with a computerized on-line visual feedback system responding to pinch force variation was designed and constructed. Mechanical testing of the device included step loading, loading-unloading cycles and 4 hours of constant loading to evaluate hysteresis, nonlinearity and signal shift over time. Calibration coefficients were calculated in the active range of 0 to 100 Newtons. A pilot test was then conducted using normal subjects (n=6). The experimental session for each subject consisted of a total of 30 trials: one trial per pinch span (12.3, 31.4 and 51.7 mm) to determine the maximal force (MF), and three repeated measures per force target (FT) level (25, 50 and 75 per cent of MF) per span. Data was filtered (Fc=10 Hz) and then normalized in terms of Ff level. Overall, subjects achieved better pinch force control at lower FT levels and at the thickest span tested. This study provided the basis for a clinical pilot test to determine the effectiveness of this rehabilitation tool in re-educating functional pinch in patients with sensorimotor impairments.","PeriodicalId":294120,"journal":{"name":"Proceedings of the 1996 Fifteenth Southern Biomedical Engineering Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125422048","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}

Recently, Oil Red O (ORO) stain was used in identifying these particles in the tissues retrieved from the failed implants. The objective of the authors' study was to examine the effect of two micron polyethylene particles (4 mg) implanted into the rabbit knees for periods of 6 and 9 months. The authors examined the sections of liver, kidneys, popliteal lymph nodes, femurs and tibias to detect the presence of UHMWPE particles. Soft tissue or bones were first embedded in paraffin blocks and five micron sections were cut. One section was stained with Hematoxylin and Eosin (H&E) stain and the other with ORO stain. The slides were viewed under a polarized light using a light microscope. The results showed the presence of the polyethylene particles in the soft tissues such as liver, kidneys and popliteal lymph nodes as well as in the tibia and femurs. They demonstrated that these polyethylene particles are easily seen either with H&E or ORO stain. They were either round or needle shaped. A visible comparison of tissue sections appeared to indicate the presence of greater number of particles in the specimens from the 9 month animal than those seen in the 6 month animals.","PeriodicalId":294120,"journal":{"name":"Proceedings of the 1996 Fifteenth Southern Biomedical Engineering Conference","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125621253","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}
