Energy-Harvesting Mesofluidic Impulse Prosthesis: e-MIP

Evaluation of an Energy-Harvesting Mesofluidic Impulse Prosthesis (e-MIP) in Transtibial Prosthesis Users

The purpose of this research is to validate the e-MIP design and function by testing the ability of e-MIP to harvest energy and return a sufficient amount of energy to assist the user during gait. The investigators will also evaluate whether prosthetic users are able to wear and use the e-MIP device long-term.

• Ability to walk independently and for an extended length of time (walking ability of each individual will be assessed by the principal investigator or study prosthetist during the recruitment period)
• Ability to communicate individual perceptions
• Ability to provide informed consent

Exclusion Criteria:

• Confounding injury or musculoskeletal problem
• Pregnancy
• Lower limb peripheral neuropathy
• Symptomatic cardiovascular disease or chronic obstructive pulmonary disease
