The analysis predicts the stress states within the plantar aspect tissue during a variety of shoe conditions. Shoe soles with a range of elastic properties are modeled in an attempt to find a shoe sole that minimizes peak stresses within the foot's soft tissue. This presently simplified and idealized model of the foot and shoe during mid-stance demonstrates significant dependency of stress development within the tissue on shoe elastic properties. These results would seem to justify further more detailed and realistic modeling of shoeing mechanics, and systematic efforts to correlate physical measurements and clinical experience with the trends indicated by finite element analyses.</p>","PeriodicalId":75645,"journal":{"name":"Bulletin of prosthetics research","volume":"10-35 ","pages":"27-34"},"PeriodicalIF":0.0,"publicationDate":"1981-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18346299","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}

Ferrographic analysis of these particles is providing new insight into the manner in which joints undergo wear in situ.

Wear particles interact with periarticular cells and tissues, provoking the release of lytic enzymes and eliciting other biochemical changes, which exacerbate the destruction of the joint.</p>","PeriodicalId":75645,"journal":{"name":"Bulletin of prosthetics research","volume":"10-36 ","pages":"13-26"},"PeriodicalIF":0.0,"publicationDate":"1981-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18094236","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}

A practical curb-climbing aid for wheelchair-bound paraplegic persons (a progress report). 一种实用的助坐轮椅的截瘫者爬路边的工具(进展报告)。

Data on testing of the system with trained and untrained able-bodied male and female subjects is reported; very limited testing with paraplegics suggests that their performance may almost equal that of the able-bodied. Advantages claimed include simplicity, light weight (8 lb), and low cost. Required modification of a standard wheelchair is limited to welding a simple bracket to the outer end of each extended main wheel axle. With ramps and control rods mounted ready for prompt use, chair width is increased by a total of 6 in. When the chair is used indoors or no curbs are expected, a paraplegic occupant, unaided, can dismount the ramps and rods and store them in a canvas bag hanging from the seat back. In this configuration the chair is only 1 in wider than its original unmodified width. Further testing with handicapped occupants is intended. Good arm, hand, and lower-back strength and movement, plus good coordination, are user requirements.</p>","PeriodicalId":75645,"journal":{"name":"Bulletin of prosthetics research","volume":"10-34 ","pages":"13-9"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18273659","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}
