| Abstract | BACKGROUND: In-shoe pressure redistribution to provide relief of forefoot pain in rheumatoid arthritis (RA) is based on assumed links between pressure and pain. However, little is known about the size of the pressure change required to reduce pain or the capacity of other plantar regions to bear increased pressure. Our primary aim was to quantify the plantar pressure pain threshold (PPT) in RA and compare it to age- and gender-matched control participants. MATERIALS AND METHODS: This controlled trial involved 10 RA participants and 10 age- and gender-matched control subjects. PPT, measured using a force gauge, and touch sensitivity, measured via Semmes-Weinstein monofilaments, were tested in 19 plantar regions. RESULTS: RA plantar PPTs were significantly reduced in eight foot regions (p < 0.05) and were more uniform across the plantar surface. Touch sensitivity was not different between groups. Plantar PPT was significantly related to age (p < 0.05) and to touch sensitivity (p < 0.05) in multiple foot regions of the control group but not in RA. PPT was significantly correlated with disease duration (p < 0.05). CONCLUSION: Plantar PPTs in RA were 60% to 80% of the control group and may be helpful in predicting the amount of pressure reduction needed to relieve pain. This study provides further evidence that RA disturbs normal pain sensory mechanisms. |

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.
