Hybrid Electrical-Mechanical Pump for Vacuum Suspension of Prosthetic Sockets

Apr 4, 2020
INTERVENTIONAL
Conditions
Summary
Prostheses can be suspended from the amputated limb using a variety of techniques, such as straps and suction. Suspending the prosthesis by creating a vacuum between the prosthetic socket and limb using a pump has benefits over other techniques including improved limb health and mobility. A new pump design will be tested by prosthesis users in the laboratory to verify its functionality during walking.
Eligibility
Inclusion Criteria4
- Ability to stand quietly and walk for 10 minutes continuously without an assistive device (e.g. cane or walker) and without undue fatigue or health risks
- Pre-classified clinically to be at least a limited community ambulator of Medicare Functional Classification Level (K)2
- Residual limb in good health
- At least six months experience with a definitive prosthesis that utilizes vacuum assisted suspension
Exclusion Criteria2
- Pathologies aside from amputation or taking medicine that would influence walking or balance
- Poor prosthetic fit or poor residual limb sensation
