3. Project Background Farming and ranching are dangerous occupations Bureau of Labor Statistics: in 2011 in the USA, farming and ranching together had the 7 th highest fatality rate (25.3 per 100,000 FTE workers) 2 nd highest number of fatalities (260) ©2012 Northwestern University Prosthetics-Orthotics Center for Education and ResearchAgrAbility NTW — 3

4. ©2012 Northwestern University Prosthetics-Orthotics Center for Education and Research extraction from corn picker extraction from grain auger 5 to 6 % will be major amputations (Brown, 2003 ) The National Safety Council reported that among agricultural workers “one out of every ten… will suffer an amputation while on the job” (Kircher, 2003) AgrAbility NTW — 4

5. The National Institute on Disability and Rehabilitation Research (NIDRR) identified farmers with disabilities as an underserved population with regard to assistive technology (Office of Special Education and Rehabilitative Services, 2008) Many disabled farmers and ranchers are geographically isolated, working in remote settings far away from amputee clinics and prosthetics services ©2012 Northwestern University Prosthetics-Orthotics Center for Education and ResearchAgrAbility NTW — 5

6. Project Goals 1.Identify activities supported or hindered by use of a prosthesis 2.Document best practices and provide this information as educational materials to farmers and ranchers and to the prosthetists who serve them 3.Improve prosthetic technology through analysis of failed components and engineering development projects ©2012 Northwestern University Prosthetics-Orthotics Center for Education and ResearchAgrAbility NTW — 6

7. Collaboration Our project is a collaboration with the National AgrAbility Project funded by the U.S. Department of Agriculture AgrAbility provides services to farmers and ranchers with disabilities, including technical assistance, information dissemination and professional training to consumers and professionals ©2012 Northwestern University Prosthetics-Orthotics Center for Education and ResearchAgrAbility NTW — 7

8. First Step … Gather information to: 1.Determine specific problems encountered by farmers and ranchers who use prostheses or had tried and abandoned the use of prostheses 2.Better understand the prosthetic needs of farmers and ranchers with amputations by gathering information with an engineering perspective Identify -components -suspension techniques -materials used -failure modes ©2012 Northwestern University Prosthetics-Orthotics Center for Education and ResearchAgrAbility NTW — 8
