In plain words

What the trial is, and whether it could suit you

People with lower extremity amputation (LEA) have persistent problems with balance, falls, residual limb pain, functional mobility, cognitive attention during gait, and satisfaction with participation in daily activities, despite using prostheses. The purpose of this randomized clinical trial is to advance understanding of how dynamic foot design features may help people with LEA This study will include people with above-knee amputations, or with bilateral amputations, or with below-knee amputations and lower levels of mobility. The main study questions/goals are: 1a) To determine if frontal plane adaptation in a foot prosthesis impacts performance, comfort, activities of daily living, and community mobility in the study populations. To answer this question, we will compare a locked and unlocked version of the novel prosthesis. 1b) To determine how the unlocked investigational foot co

📋 Eligibility rules (as published)
Inclusion Criteria: * Participants will be 16-years or older, regardless of gender, race, or ethnicity. * Potential participants should reside in the community or an independent living environment. * The upper weight limit is 165.6 kg (365 lbs.). * Prosthetic foot sizes 22 cm (approximate US Men's shoe size 5) up to 30 cm (13 US Men's). * Ability to walk more than 400 m on level ground without an increase in pain. * At least one year post-amputation and using a prosthesis * People must have the ability to read, write, and comprehend English. Exclusion Criteria: * Participants must not have conditions such as skin wounds that preclude the use of a prosthesis. * People will be excluded if they have fluctuating conditions that may significantly alter gait mechanics during the \~10-week study. Examples include Parkinson's disease, alcoholism, brain tumor, and hereditary cerebellar ataxias. * Participants may use a walking aid but should not primarily rely on wheelchair mobility. * People will be discontinued from the study if they become unable to use a prosthesis. Examples include major surgery and trauma. However, because of the potential for fluctuations in prosthesis use with this population, short-term issues will not disqualify people from continued participation when they resume prosthetic use.
