| Abstract | Gait characteristics during stair descent have been characterized for a straight descent path; however, pedestrians are likely to encounter a variety of staircase designs that allow one to descend at an angle (i.e. an oblique or monumental staircase). The purpose of this study was to determine the temporospatial lower limb joint kinematics differences between descending a staircase on straight versus oblique descent paths. Sixteen subjects (8 males, 8 females) descended a staircase under three different conditions: straight descent and at a 25° and 45° angle compare to the straight path. Cycle time, cadence, speed, step width, and step length were significantly affected by descent angle, while the proportion of the cycle dedicated to the stance and swing phases remained constant over the descent paths. Peak knee flexion angle increased by approximately 2.5° in the 45° condition compared to the 0° condition (p=0.0044); however, the remainder of the time series was unchanged. A decreased step width and increased step length occurred to allow the foot to sufficiently clear the steps. Changes in the temporospatial variables, hip joint angle and a constant stance/swing proportion demonstrates that these adaptations may be made to maintain characteristics of the gait cycle and prevent subjects from adopting an unfamiliar gait pattern. |

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.
