Scheck & Siress partners with Northwestern University for multi-year clinical trial


Scheck & Siress and Northwestern University Orthotic Prosthetic Center have partnered in a multi-year clinical trial funded by the Department of Defense.

The clinical trial, “Functional Performance Evaltion of the NU-FlexSIV for Persons with Transfemoral Amputation“, is designed to compare the newly developed Northwestern University Prosthetics-Orthotics CenterNU-FlexSIV prosthetic leg socket to current standard prosthetic options.

The NU-FlexSIV has been developed as a more comfortable and functional alternative to the current prosthetic leg socket options available. These advancements propose that they can greatly improve the quality of life for persons with transfmoral amputations, especially military persons who are typically young, and who wish to return to previous activity levels.

The primary aims of the study are:

  • To demonstrate if the NU-FlexSIV Socket is more comfortable than the IC socket.
  • To demonstrate if the NU-FlexSIV Socket results in better functional performance than the IC socket.
  • To demonstrate the NU-FlexSIV Socket will result in better quality of life and “satisfaction with device” (i.e. prosthesis) than the IC socket.

The study has been designed as an “assessor-blinded prospective randomized cross-over trial”, meaning that all subjects will receive all treatments and that all subjects will participate for the same number of periods.

Scheck & Siress’ Michael Oros & John Angelico have been collaborating on the clinical trial while Ryan Caldwell has been a co-investigator. 

Northwestern University and Scheck & Siress will be conducting and reporting critical data on their developments. Both institutions continue to pride themselves on staying in the forefront of prosthetics and orthotics.
