Kinematic, Kinetic, and Metabolic Comparison of Bilateral Transfemoral Ambulation With Passive Versus Powered Prosthetic Devices

April 3, 2019 updated by: Dana Craig, Southern California Institute for Research and Education
The purpose of this descriptive and exploratory pilot study is to investigate: (1) sagittal plane hip kinematics and kinetics and (2) metabolic consumption/cost, for bilateral transfemoral walking with passive prostheses versus powered prostheses. The pilot study will collect data from three subjects with bilateral transfemoral amputations. Differences in kinetics, kinematics, and oxygen consumption/cost when comparing passive and powered components may indicate benefits for clinical application of powered devices for persons with lower limb amputation.

Description

Inclusion Criteria:

  • Male or female
  • All causes of limb amputation: congenital, trauma, vascular, limb salvage, infection.
  • All transfemoral residual limb lengths: joint disarticulation, long, medium, short, very short.
  • Subjects currently walk with entirely passive type prostheses daily.
  • Subjects walk without assistive devices OR with single point cane.
  • High-activity level walkers

Exclusion Criteria:

  • Ages < 18 or > 45 years
  • Medical comorbidities or existing conditions that may impede the subjects ability to complete the protocol excluding the amputations.
  • Current medications or pharmaceutical interventions that may impede the subjects ability to complete the protocol.
  • Any powered prosthetic component or prosthesis, including but not exclusive to: Ossur Proprio Foot, BiOM or BiOM T2 System Foot, Ossur Power Knee, Ossur Symbionic Leg.
  • Subjects requiring a walker, crutches, quad cane, or other assistive devices excluding a single point cane.
  • Low-activity level walkers
