Validação do questionário foot ankle ability measure (FAAM) para participantes com tendinopatia do tendão do calcâneo

Abstract

The Foot and Ankle Ability Measure (FAAM) has not yet been tested and validated specifically in participants with Achilles Tendinopathy (AT). The aim of this study was to validate the FAAM for participants with AT. 101 volunteers with AT completed the FAAM, Lower Extremity Functional Scale (LEFS), and Victorian Institute of Sport Assessment (VISA-A), on two occasions with 2–3-day intervals between them. The clinimetric properties were analyzed: internal consistency, test–retest reliability, measurement error, construct validity, and ceiling and floor effects. The FAAM ADL and FAAM Sport subscales showed good internal consistency (Cronbach’s α = 0.84 and 0.89), good test–retest reliability (ICC2.1 reliability FAAM ADL 0.81, 95%CI = 0.7 to 0.87 and FAAM Sport 0.85, 95%CI = 0.78 to 0.90), measurement error (standard error of measurement [SEM] = 7.68 and Smallest Detectable Change [SDC] = 21.30 from a subscale of function in the activities of daily living [FAAM ADL]; SEM = 6.52 and SDC = 18.09 from the FAAM Sport), construct validity found a strong correlation (rho = 0.67 comparing the FAAM Sport versus VISA-A and rho = 0.68 comparing the FAAM Sport versus LEFS), and no ceiling and floor effects. Concludes that the FAAM questionnaire is valid and reliable for use in the population with AT and is a good tool in scientific research and clinical practice.
