| Abstract | A Prosthetic Foot Loading Apparatus (PFLA) was modified and improved to measure the mechanical properties of different prosthetic feet. In this paper the properties of a SACH foot and a Flexwalk foot are examined to demonstrate application of the device. Roll-over shape of the feet was determined using a shank-based coordinate system. Damping ratios (/spl zeta/=0.064 for SACH and /spl zeta/=0.028 for Flexwalk) and resonant frequencies (/spl omega//sub n/=5.46 Hz for SACH and /spl omega//sub n/=2.90 Hz for Flexwalk) were also obtained. Roll-over shapes and damping ratios influence foot performance during walking. The PFLA is valuable for determining mechanical properties of commercially available prosthetic feet and as well as for evaluating design prototypes for new prosthetic feet. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
