Research project: Analysis of stump tissue mechanics of lower limb amputees

Currently Active: 

Discomfort and pain have been a long standing concern for stumps of lower limb amputees. In severe cases, skin and/or tissue injuries may occur due to excessive and prolonged load bearing at the stump/socket interface, which could not only affect the stump health, but also ultimately reduce the outcome of prosthesis usage.

This project aims to analyse stump tissue loading/unloading mechanics using FEA and tissue damage model with a view to providing a prognostic evaluation of the loaded stump. The developed approach and results could be potentially expanded to many areas where pressure ulcers are considered pervasive e.g. diabetic foot care, special seating etc.
