ProFit Study

Prosthetic Fit Assessment in Transtibial Amputees Secondary to Trauma (ProFit)



Principal Investigator: Saam Morshed, MD, PhD


The aims of this study address an exploratory endpoint in the Transtibial Amputation Outcomes Study (TAOS), a trial currently underway in METRC centers which will investigate prosthesis fit, alignment and condition of the residual limb. As there are no validated measures of fit and alignment (factors known to impact comfort, function and performance among amputees) the TAOS study includes a provision in the protocol for acquisition of photographs, video and radiographs 18 months following amputation in order to help develop uniform assessments of the residual limb. The goal of this ancillary study is to validate and refine a 42 item prosthetic assessment tool (ProFit) that was developed by an expert panel of certified orthotist prosthetistis (CPOs) in collaboration with orthopaedic trauma investigators, a measurement scientist and a biomedical engineer from the BADER consortium for use in future research. It may also be applicable for use in clinical settings.


This study is being funded by Dept. of the Army (USAMRAA) under contract number: OR130357.
