Background: Musculoskeletal conditions of the foot/ankle are highly prevalent, both in normal and sports contexts, having Physiotherapy a prominent role in their treatment. It is necessary to use self-reported measurement instruments for proper evaluation of the impact of these conditions on the individuals, as well as the impact of the treatment. The Foot and Ankle Ability Measure (FAAM) is a self-reported measure of assessment of physical function in patients with musculoskeletal conditions of the foot/ankle.
Purpose: Cross cultural and linguistic adaptation of the FAAM and respective validation and evaluation of the responsiveness to the Portuguese population.
Methods: The cultural and linguistic adaptation was achieved by the sequential methodology. For the evaluation of the psychometric properties, FAAM and VR-12 were administered to a sample of 179 individuals. The data collection was made in three stages: at T0 (beginning of treatment), Test-Retest (FAAM - two days later), T1 (end of treatment).
Results: We obtained the FAAM-PT with semantic and cultural equivalence with the original version. The FAAM-PT achieved high levels of internal consistency (Cronbach α ADL= 0.98; Cronbach α Sports = 0.95) and reproducibility (ICC ADL= 0.90; ICC Sports = 0.84). It demonstrated good construct validity through the Principal Component Analysis, and the relations with the VR-12 summaries (r between 0.241 and 0.575) and related discriminatory questions (BMI, r between -0.212 and -0.290; and Walking aids, p=0.000). It showed good reproducibility (Effect Size (ES) ADL=0.78; ES Sports=0.94; Standardized Response Mean (SRM) ADL=0.87; SRM Sports =1.00) and good interpretability (Standard Error measurement (SEM) ADL=3.14; SEM Sports=5.60; Minimal Detectable Change (MDC) ADL=8.71; MDC Sports=15.51; Minimal Important Change (MIC) ADL=5.96; MIC Sports =19.06).
Conclusion(s): FAAM-PT proved to be a valid, reliable and responsive measure for individuals with musculoskeletal conditions of the foot/ankle, it is recommended both in research and in clinical practice.
Implications: Promote and provide outcome measures to the Portuguese physiotherapists.
