The walking pattern and comfort of a person with lower limb amputation are determined by
the prosthetic foot's diverse set of mechanical characteristics. However, most design …

People with lower limb amputations face considerable challenges to everyday mobility that
affect their quality of life. This is especially the case in low and middle income countries …

People with lower-limb amputation in low-and middle-income countries (LMICs) lack access
to adequate prosthetic devices that would restore their mobility and increase their quality of …

Advances in understanding the effects the mechanical characteristics of prosthetic feet on
user biomechanics have enabled passive prostheses to improve the walking pattern of …

Current high-performance prosthetic feet work well for many users, but the low resolution of
size and stiffness categories may limit walking performance for certain users. A line of …

This paper presents a novel framework that quantitatively connects the mechanical design of
a prosthetic foot to its anticipated biomechanical performance. The framework uses kinetic …

A method is presented to optimize the shape and size of a passive, energy-storing prosthetic
foot using the lower leg trajectory error (LLTE) as the design objective. The LLTE is defined …

Background Prosthetic foot stiffness, which is typically invariable for commercially available
prosthetic feet, needs to be considered when prescribing a prosthetic foot. While a biological …

An experimental prosthetic foot intended for evaluating a novel design objective is
presented. This objective, called the lower leg trajectory error (LLTE), enables the …

Unilateral below-knee amputees develop abnormal gait characteristics that include bilateral
asymmetries and an elevated metabolic cost relative to non-amputees. In addition, long-term …
