Study to Compare a Microprocessor Controlled Prosthetic Ankle-Foot Against a Carbon Fiber Prosthetic Ankle-Foot in Transtibial Amputees

Ability Prosthetics and Orthotics, Inc. is performing a research study to compare the benefits of two prosthetic ankle-foot devices. The goal is to learn whether a recently developed microprocessor controlled prosthetic ankle-foot device, called the Kinnex, provides an advantage to walking and mobility when compared to a carbon fiber prosthetic ankle-foot devices called the LP Pacifica.  Both prosthetic ankle-foot devices are manufactured by Freedom Innovations, LLC (Irvine, CA).

We are looking for lower limb amputees who meet the following criteria:

  • Have a below knee amputation on one side
  • Between 18 and 99 years’ old
  • Use prosthesis 8 hours a day or more
  • Have well-fitting prosthesis
  • Body weight below 275 lbs.
  • Able to walk unlimited in community (K-level 3)
  • No use of ambulatory aid (no cane or walker)
  • English speaking
  • Non-pregnant

By participating in this study, your walking ability with a prosthesis may get better, stay the same, or get worse. A possible risk is wearing a prosthesis you are not accustomed to could lead to decreased stability and a potential fall. Your participation in the research study may improve access to microprocessor controlled ankle-foot prosthetic devices, because of an increased understanding of the benefit they can provide. You will receive compensation for travel for research visits.

The research study will be performed over a series of three visits, each lasting about three hours. Ability Prosthetics and Orthotics, Inc. will administer the study at the following three locations:

Ability – Hagerstown, MD 246 Eastern Boulevard, Suite 100 Hagerstown, MD 21740

Ability – York, PA 960 South George Street York, PA 17403

Ability – Charlotte, NC 309 S. Sharon Amity Road, Suite 104 Charlotte, NC 28211

Having Your Prosthesis Changed?

Volunteer with Bioengineering Research

The University of Washington is conducting research into improving socket fit for below-knee amputees. We are investigating how continuously monitoring residual limb volume could lead to improved management of socket fit.

Seeking amputee volunteers to help develop the future of prosthetics.

  • Have a below-knee amputation
  • At least 18 month since amputation
  • Able to walk
  • Over the age of 18

Study Focus: Help evaluate a new tool to improve socket fit.
$50/hr + transportation costs
2 days total, 6-8 hours per day. Visit before and after socket, liner, or suspension changes are made. 
Location: University of Washington or a location near you.

The Department of Physical Medicine & Rehabilitation is conducting a study involving Transtibial (Below Knee) Amputees

Volunteers are needed for a research study investigating a new immediate fit prosthesis to determine comfort and functionality during a two week home trial.

We are looking for men and women who:

  • are transtibial or below knee amputees (one year or more since amputation)
  • weight under 250 pounds

–    are 18 yrs. old and older

–    are currently using a functional prosthesis

–    have no skin ulcerations/rashes on the limb

–    have no central nervous system disorders such as stroke or    brain injury that could interfere with safe walking

–   have no severe phantom or limb pain

 All initial prosthetic fitting and follow up occur at:

Department of Physical Medicine & Rehabilitation 

Penn Medicine at Rittenhouse Bldg., 1st floor 

1800 Lombard St., Philadelphia, PA 19146 

Principal Investigator: Dr. Tim Dillingham
