Construct validity, responsiveness, and interpretability of the Spinal Cord Injury Functional Ambulation Inventory (SCI-FAI).
Observational study in The journal of spinal cord medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveWe investigated the construct validity, responsiveness, and interpretability of the Spinal Cord Injury Functional Ambulation Inventory (SCI-FAI) to determine its usefulness in measuring the functional level of gait. PATIENTS AND
methodsThis was a prospective observational study following the checklist of the Consensus-Based Standards for Selecting Health Measurement Instruments. The SCI-FAI consists of three items: Gait Parameter, Assistive Devices, and Temporal. We recruited 55 patients diagnosed with a spinal cord injury (SCI) in the subacute or chronic phase from Ibaraki Prefectural University of Health Sciences Hospital. Construct validity was clarified by hypothesis testing and the rate of hypothesis verification. We divided responsiveness into subacute and chronic groups and determined the correlation between the changes in the two timepoints of the SCI-FAI and 6-minute walk test. Interpretability involved the calculation of cutoff values for indoor and outdoor walking.
resultsConstruct validity was confirmed for 12 of the 15 hypotheses, indicating high construct validity. In the subacute group, Gait Parameter and Assistive Devices showed moderate responsiveness. Interpretability showed that the Gait Parameter was perfect in 19 of the 20 subjects who did not need a walking aid when walking. The cutoff value for Gait Parameter for indoor walking was 17.5 points (AUC 0.91) and that for Assistive Devices was 9.5 points (AUC 0.88). The cutoff values for outdoor walking were Gait Parameter 18.5 points (AUC 0.96) and Assistive Devices 10.5 points (AUC 0.94).
conclusionOur results demonstrated that the SCI-FAI has adequate construct validity, moderate responsiveness in SCI patients in the subacute phase, and interpretability in the gait assessment of individuals with SCIs. Gait Parameter is likely to show a ceiling effect for people with SCIs who can walk without using an upper-limb walking aid.
