Customized footwear with appropriate insole material for offloading is widely used for preventing ulceration in diabetic and leprosy affected patients. Methods: Computer based finite element analysis was carried out on a 3 dimensionally modelled insole. The insole was tested with the boundary condition of constant geometry, constant loading and varied material properties to identify the biomechanical behaviour of material. Results: A total of 7 commonly used insole rubber materials including Butyl Rubber, Ethylene Vinyl Acetate (EVA), Isoprene, Natural Rubber, Neoprene, Polyurethane and Micro Cellular Rubber (MCR) were tested using finite element analysis. The study exhibited low deformation and stress values for EVA. High deformation and stress values were seen in MCR. Conclusion:The comparison of insole materials provides health workers with the required knowledge for selection of appropriate material for therapeutic insoles. The mechanical analysis of materials through the computer aided analysis will help the therapeutic footwear technician and designer to design, fabricate and use appropriate insoles.

Physical Rehabilitation in Leprosy
An orientation in leprosy was undertaken for final year medical students by Schieffelin Institute of Health -Research, Leprosy Centre (SIH-RLC), Karigiri with the objective of transferring knowledge and skills related to the diagnosis and treatment of leprosy and its complications, so that these would be useful later when they have to deal with patients affected by leprosy, especially in the Primary Health Centres. The Leprosy orientation program was of one-day duration and was organised in three Government Medical Colleges every year between 2016 to 2018. Pre and post-test questionnaires were used to assess leprosy knowledge before and after the orientation. During the orientation the facilitators transferred knowledge and skills required for management of leprosy through interactive and practical sessions. Each participant was followed up two years later when a simple questionnaire was sent to them to assess the impact of the leprosy orientation in diagnosis and management of leprosy in their respective work areas. The questionnaire was sent as a link to the medical student's mobile phones for their responses. The pre and post test scores showed significant improvements. This difference was statistically significant. The follow-up questionnaire showed that students who underwent this leprosy training were able to diagnose and treat leprosy in their work area. Leprosy orientation also helped them to identify and treat leprosy complications/or refer patients to appropriate centres for further management. Selective and targeted training of final year medical students helped to improve their knowledge and skills to diagnose and treat leprosy and its complications later in their work situations, especially in the Government Primary Health Centres (PHC).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
