Abstract

Amputees may complain of pain at the stump while wearing their prostheses. High stresses applied onto the stump which is not particularly tolerant to loadings is a major cause of the pain. Various experiments and finite element (FE) analyses have been performed to study the stress distribution at the socket-limb interface. In addition to the stress distribution, knowledge of the load tolerance of the stump is essential for the improvement of comfort.

There were few investigations studying the pain response to stresses applied onto the stump. Those investigations, however, focused on one particular region of the stump or the global response of the stump to external load. Quantitative load tolerance over different regions of the stump have not received much attention.

The objective of this study was to evaluate and compare the load tolerance over different regions of the stump among trans-tibial amputees. With the help of FE analysis, the stress distribution on the soft tissue corresponding to the depth of indentation when pain is reached was investigated.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
