| Abstract | The paper discusses an ART-1-based artificial neural network (ANY) adapted to controlling functional electrical stimulation (FES) to facilitate patient-responsive ambulation by paralyzed patients with spinal cord injuries. This network is designed to control FES systems developed by the first author and that is presently in use by over 400 patients worldwide (presently without ANN control) and which is the first and the only FES system approved by FDA. The network that is considered discriminates patterns of above-lesion upper-trunk electromyographic (EMG) time series to map patient's posture for activating standing and walking functions under FES and it controls FES stimuli levels using response-EMG signals to overcome muscle fatigue. The neural network also adaptively controls patient's postural stability via identifying changes in posture through acceleration/gravitational/weight sensors. The network trains itself to adapt to physiological changes of the patient, and it overcomes decision and control errors by simple punishment inputs from a single manual punishment switch. The system thus, is both self adaptive and patient-responsive through a combinations of neural EMG signals and an artificial neural network to achieve patient responsive ambulation using stimulation of the patient's own peripheral motor neurons, namely his own peripheral neural network. |

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.
