Subject: Request for prosthetist feedback on lower-limb socket volume control devices

     Dear List-member

     At the Department of Bioengineering, University of Washington,
     we are embarking on a study of the biomechanical behavior of
     devices that actively control socket volume.

     Examples of these include

      1. Otto Bocks' Air Contact System
      2. Otto Bocks' Silicone Liner
      3. Prosthetic Concepts' Pneu-Fit
      4. Michael Love's Pump IT Up System

     We are interested in getting feedback from users of these devices,
     on the relative benefits and disadvantages of the these systems.

     If you have fitted, or are using, below-knee or above-knee sockets
     with active volume-control, we would like to hear from you.

     We are specifically interested in how effective these
     products are in compensating for day-to-day changes in the volume/shape of
     the residual limb, and whether these have a perceptible effect on
     skin abrasion/irritation.

     If you have experience with the products listed above or with any other
     similar inflatable devices please reply with the name of the product to:

      <Email Address Redacted>

     We plan to initially build a database of amputees and prosthetists
     who can advise us. As the research continues we may ask you to reply to
     specific questions about the products you have experience with.

     Thanking you,

      Joan E. Sanders, Ph.D.
