lower extremity amputation
HEAT
In 2005, the number of person living with the major lower extremity amputation was 1.6 million, this number is projected to increase by approximately 2.2 fold by 2050Sweat (moisture) and heat build-up at the skin-liner interface remains a major challenge that reduces the quality of life for amputees. According to a systematic review of associated factors and questionnaires, it has been documented that heat and sweat are leading complaints that result in a reduced quality of lifeElevated skin temperature and sweat build-up are commonly associated with wearing and using prosthetic liners that are primarily made of occlusive materials that retain heatThere are limited rigorous scientific studies that clearly provide evidenced-based guidelines to the prosthetist in selection of liners from numerous available options. A need to develop objective metrics to evaluate a liner along with scoring for patient satisfaction has been identifiedComponents of vented liner-socket system used in the study.
