Translation, cross-cultural adaptation, and validation of the Italian version of the Synkinesis Assessment Questionnaire in individuals with peripheral facial palsy.
Observational study in European journal of physical and rehabilitation medicine, 2022. 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
backgroundAfter peripheral facial palsy, the onset of facial synkinesis results in aesthetic disfigurement and local muscle tension or pain, with possible deterioration of patient's well-being and social participation. The availability of valid instruments to evaluate patient-reported severity of facial synkinesis is important to capture the subjective perception of facial impairment.
aimTo generate and validate an Italian version of the Synkinesis Assessment Questionnaire, a patient-reported outcome measure to assess patient-perceived severity of facial synkinesis after peripheral facial palsy.
designObservational study.
settingOutpatient clinic of a Rehabilitation Unit. POPULATION: Seventy-five patients with peripheral facial palsy.
methodsThrough a process of translation and cross-cultural adaptation, we generated the Italian version of the questionnaire (SAQ-IT) and administered it twice to patients with peripheral facial palsy. We evaluated the clinical severity with the Sunnybrook Facial Grading System (SFGS) and the physical and social/well-being function with the two subscales of the Facial Disability Index (FDI-PHY and FDI-SWB, respectively).
resultsCronbach's alpha was 0.87. Item-total correlations ranged from 0.30 to 0.70, while inter-item correlations ranged from 0.15 to 0.82, with an average value of 0.48. Test-retest reliability showed an Intraclass Correlation Coefficient of 0.946 (95% confidence interval: 0.916-0.966). The minimum detectable change (with a 95% confidence level, MDC<inf>95</inf>) was 13.14 points. The correlation between SAQ-IT and the SFGS synkinesis subscore was rho=0.74, while that with the SFGS composite score was rho=0.25, with the FDI-PHY rho=-0.11 and with the FDI-SWB rho=-0.13.
conclusionsOur study validates the SAQ-IT in Italian-speaking individuals with peripheral facial palsy, confirming its acceptable psychometric properties, and providing the MDC<inf>95</inf>. CLINICAL REHABILITATION IMPACT: The availability of a valid instrument for the evaluation of patient-perceived severity of facial synkinesis plays an important role in the definition of tailored rehabilitative interventions after peripheral facial palsy.
