| Abstract | Rotations of the humerus in the human shoulder girdle are usually described using five classical medical definitions: flexion/extension, abduction/adduction, internal/external rotation, horizontal abduction/adduction, and horizontal flexion/extension. The latter two are needed to overcome the inability of the first three to define the full range of motion. The International Society for Biomechanics recommendations reduce these to three sequential rotations around perpendicular axes: rotation of the plane of elevation (horizontal rotation), elevation, and axial rotation. We expand on this work by providing a new and intuitive visualization method to display these rotations that superimposes the axial rotation on the map projection of the reachable workspace of the elbow. We provide methods to interpret and create the visualization using direct observations, but also the equations and Matlab scripts needed to use the method. The visualization allows the immediate observation of the full rotational range of motion of the humerus and the interaction effects between these physiologically coupled rotations. Furthermore, it allows visualization of the effects of kinematic limitations of external devices such as endpoint manipulators or exoskeletons. Therefore, the new visualization method is useful for both clinical diagnostics and device development. |

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.
