What the study is about

The investigators will assess biomechanical and functional mobility outcomes in individuals with unilateral, above-knee amputations using different knee/ankle configurations of a lightweight powered prosthesis and different volitional controllers in individuals with unilateral, above-knee amputations.

Being studied: Powered and passive lower limb prosthesis and control

Conditions: Lower-Limb Amputation

Eligibility criteria

Copied from the official record. The study team makes the final decision at screening.

Show full criteria

Our inclusion criteria will be

  • Above-knee amputation
  • K2/K3/K4 ambulators
  • At least 18 years old
  • At least one year since amputation
  • At least six months since the definitive prosthesis fitting
  • Currently prescribed and using a mechanically passive or microprocessor-controlled prosthesis

Our exclusion criteria will be

  • Over 350 lbs. body weight, the weight limit for our safety suspension systems
  • Cognitive deficits or visual impairment that could impair their ability to give informed consent or to follow simple instructions during the experiments
  • Pregnant women due to elevated safety concerns for this population
  • Co-morbidity that limits their ability to participate in the study protocol (e.g., stroke, pacemaker placement that would interfere with the powered prosthesis, severe ischemia, cardiac disease, etc.)
  • Adults who are unable to consent
  • Individuals who are not yet adults (infants, children, teenagers)
  • Individuals who use a wheelchair for mobility both outdoors and indoors because they may not be able to perform the necessary activities with their passive prosthesis or the powered prosthesis
  • Prisoners, due to concerns with informed consent
