Measuring long-term outcome in people with lower limb amputation: cross-validation of the Italian versions of the Prosthetic Profile of the Amputee and Prosthesis Evaluation Questionnaire.

Aim: Recently 2 questionnaires have been developed for people with lower limb amputation to determine, in follow-up studies, the level of function and extent of prosthetic use, to measure major life domains connected with prosthesis function, and to study the factors potentially related to prosthetic use the Prosthetic Profile of the Amputee (PPA) and the Prosthesis Evaluation Questionnaire (PEQ). The purpose of the present study was: a) to produce Italian versions of both PPA (PPA-it) and PEQ (PEQ-it), using a validated procedure of cross-cultural translation; b) to analyse and discuss the internal consistency and construct validity of the main sections of the 2 questionnaires, in an Italian population.

Methods: The PPA questionnaire consists of 44 questions arranged in 6 sections.
