| Abstract | We studied the effect of body weight support on self-selected overground walking speed in both healthy elderly subjects and subjects post-stroke using the KineAssist, a novel robotic gait and balance device. Body weight support is provided by the robot via a closed-loop system that provides support about the subject's estimated center of mass. Body weight support was tested at 10%, 20%, 30% and 40% of the subject's weight. We found that self-selected walking speed decreased with greater levels of body weight support for the healthy elderly subjects. However, the subjects post stroke showed an average increase of 18% in self-selected walking speed at some level of body weight support compared with no body weight support while walking in the KineAssist. Gait speed increases corresponded to an increase in step length. There appears to be a benefit to overground walking speed when providing a small percentage of body weight support for people post-stroke. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
