| Abstract | Motor learning principles are increasingly used in robotic rehabilitation. These principles are mainly derived from reaching studies and it is currently unknown whether the same principles apply in locomotion. The aim of this study was to determine the effect of a gradually and suddenly introduced dynamic perturbation on locomotor adaptation and on recalling the adaptation when being re-exposed to the same perturbation. Subjects walked on a treadmill and adapted to a viscous force field that was applied during the swing phase. In one group the strength of the force field was gradually increased over different steps whereas in a second group it was introduced suddenly at full strength. The gradual group showed less adaptation and a faster decay of the adaptation during the washout than the sudden group. Strikingly, when both groups were being re-exposed to the perturbation at full strength, the gradual group showed no adaptation whereas the sudden group showed a faster occurring adaptation than during the first exposure. In conclusion, in contrast to the reported beneficial effects of a gradual introduction of a perturbation on adaptation in reaching, it seems to have a detrimental effect on locomotor adaptation. These results indicate that caution should be taken when applying motor learning principles solely derived from reaching studies to improve robotic gait rehabilitation. |

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.
