Clinical evaluation of the Franklin Applied Physics Cosmetic Cover for lower limb prostheses: a preliminary report

The Franklin Applied Physics (FAP) Cosmetic Cover is the result of research and development directed by Dr. Robert Erb at the Franklin Research Center, Norristown, PA. The FAP Cover is a silicone rubber cosmesis designed to improve the appearance of lower limb prostheses and provide wider social integration for the wearer. The Technology Transfer Section, Rehabilitation Research and Development Service, Department of Veterans Affairs, coordinated a pilot study of four pre-commercial covers at selected sites. Participating prosthetists and subjects evaluated fit, relevant physical criteria, and overall potential value of the cover. The following statements summarize responses of the participants: 1) well accepted with regard to overall fit, appearance, and ease of donning/doffing; 2) lightweight, highly elastic, and easy to maintain; and 3) split toe and closed toe versions are needed for above-knee and below-knee models. Data gleaned from the pilot study were used to define dimensions for standardized off-the-shelf sizing and to make recommended modifications, resulting in pre-market models that are ready for a national field evaluation.
