The Foot and Ankle Ability Measure (FAAM) is a patient-reported outcome measure (PROM) designed to be a comprehensive assessment of physical. The FAAM is a self-report measure that assesses physical function of individuals with lower leg, foot, and ankle Patient Reported Outcomes. The Foot and Ankle Ability Measure (FAAM) is a region-specific, non–disease- specific outcome instrument that possesses many of the clinimetric qualities.

The study was approved by the university’s Institutional Review Board.
Evidence of validity for the Foot and Ankle Ability Measure (FAAM).
Main Outcome Measure s: A methodological framework for assessing health indices. Scores on the Foot and Ankle Ability Measure activities of daily living and sports subscales were greater in healthy athletes than in those with chronic ankle instability and were greater in the athletes who indicated that their ankles were normal than in those who indicated that their ankles were nearly normal or abnormal.
All athletes in the healthy group and gaam athletes in the CAI group categorically rated their ankles as normal. Reliability relates to score stability, and responsiveness describes the ability of the instrument to detect changes in an individual’s status over measurd.
These data imply that, while these athletes categorically identified their ankles as normalthis clearly was not the case. Reliability and sensitivity of the Foot and Ankle Disability Index in subjects with chronic ankle instability.
If one item is not answered the highest score is 80, if two are not answered the total highest score is 76, etc. Retrieved from ” https: The score on each item are added together to get the item score total. Development and reliability of the Ankle Instability Instrument.
Content validity The specific items on the instrument and what they measure determine the evidence that is based on content. Outcomw item reduction was completed using item response theory with subjects. The distribution of participants by sport and group assignment is presented in the Table.
Validity of the Foot and Ankle Ability Measure in Athletes With Chronic Ankle Instability
Self-reported outcome instruments can be discriminative or evaluative. Conversely, data related to the minimal detectable change and the minimal clinically important difference have been identified fsam the FAAM; however, these data are specific to the population and timeframes for which they were established.
Likewise, differences in mean scores between groups were greater on the sports subscale 23 points than on the ADL subscale 12 points. Similarly, we expected that athletes oufcome CAI would rate their ankles as either abnormal or severely abnormal. The Foot and Ankle Ability Measure FAAM is a self-report outcome instrument developed to assess physical function for individuals with foot and ankle related impairments.
Br J Sports Med. Item score totals, which range from 0 to 84 for the ADL subscale and 0 to 32 for the Sports subscale, were transformed to percentage scores. In most cases Physiopedia articles are a secondary source and so should not be used as references.

Similarly, athletes with CAI in our study scored lower on both ADL and sports subscales compared with healthy athletes.
However, in the CAI group, 4 athletes rated their ankles as normal ; 10, as nearly normal ; 1, as abnormal ; and 0, as severely abnormal. Open in a separate window.
If the subject answers all 21 items, the highest potential score is Foot and Ankle Ability Measure. The Foot and Ankle Ability Measure may be used to detect outvome functional deficits related to chronic ankle instability.
Eechaute et al  level 1 concluded that the FADI measuer FAAM were meausre most appropriate, patient-assessed instruments to quantify functional disabilities in patients with chronic ankle instability, but reported that there is need for further research of the FAAM in a specific population of patients with CAI   .
Construct validity While evidence for content relates directly to what the items measure, evidence for construct validity assesses how the scores on the instrument relate to other measures of the construct.
Relationships were stronger when all athletes, rather than just those with CAI, were included in the analyses. Although we cannot be certain why 4 participants identified their ankles as normalwe suspect that the instructions on the FAAM may have influenced them.
Guyatt responsive index and ROC analysis found the ADL subscale was more responsive than general measures of physical function while the Sports subscale was not.
Therefore, we recommend that when administering the FAAM, clinicians should ascertain both measures.
