Abstract
Background
To translate and cross-culturally adapt the Questionnaire for Persons with a Transfemoral Amputation (Q-TFA) into German and evaluate initial measurement properties in adults with unilateral transfemoral amputation using a transcutaneous bone-anchored prosthesis.
Methods
Sixty-one participants completed the German Q-TFA and comparator patient-reported outcome measures at baseline and after 12-15 days. The original four-score Q-TFA structure was retained: Prosthetic Use, Prosthetic Mobility, Problem, and Global scores. Test-retest reliability, measurement error, internal consistency of the Problem Score, floor and ceiling effects, and hypothesis-based construct validity were assessed.
