The influence of prosthetic foot stiffness on energy expenditure in unilateral below-knee amputees

Abstract

This paper investigates the relationship between prosthetic foot stiffness and energy expenditure. There are a multitude of different factors that can affect prosthetic foot stiffness that should be taken into consideration when determining which foot to select for each patient. Energy expenditure is a factor that is important to healthcare professionals to consider as amputees will expend more energy than an able-bodied person. Any way to reduce energy expenditure is beneficial to the patient. This project investigated the topic of prosthetic foot stiffness and energy expenditure. Its purpose was to determine if there was an optimum prosthetic foot stiffness for transtibial amputees that would reduce energy expenditure. Following a review of existing research, there may be a correlation between the two, but further research needs to be continued on the topic. Prosthetists and other healthcare professionals must consider all available aspects that could affect in reducing energy expenditure of amputees.
