Cross-cultural adaptation and validation of the simplified Chinese version of the functional assessment scale for acute hamstring injuries (FASH) questionnaire.

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
backgroundThe Functional Assessment Scale for Acute Hamstring Injuries (FASH) Questionnaire is a tool to assess the severity of symptoms and their impact on function and sports ability in patients with acute hamstring injuries. The study was to cross-culturally adapt and psychometrically validate a Simplified Chinese version of the FASH (SC-FASH).
methodsCross-cultural adaptation was performed in accordance with the internationally recognised guidelines of the American Academy of Orthopaedic Surgeons Outcome Committee. The FASH is a 10-item questionnaire. The sample size should be 5 to 10 times the total number of items on the scale. 150 participants with acute hamstring injuries were included in this study. Cronbach's α and the intra-class correlation coefficient (ICC) were used to assess reliability, and correlations between the SC-FASH and the Exercise-Induced Leg Pain Questionnaire (EILP), the Visual Analogue Scale (VAS) and the Short Form (36) Health Survey (SF-36) were used to assess construct validity.
resultsBetween February and May 2025, 150 literate native Chinese speakers with hamstring injuries were recruited for a study. All the 10 items had an answer rate of 100%. The FASH was successfully adapted and translated into Simplified Chinese. Each item was appropriately correlated with the total items. Good reliabilities were observed in SC-FASH, evidenced by Cronbach's alpha of 0.88, an ICC 0.97 (95% CI, 0.96-0.98). The elimination of any one item did not result in a Cronbach's α < 0.80. Standard Error of the Mean (SEM) was 4.41. Good correlations were observed with EILP (0.68, p < 0.01), VAS (-0.62, p < 0.01), and physical function of SF-36 (0.62, p < 0.01). Moderate correlations were observed with role physical (0.46, p < 0.01), bodily pain (0.50, p < 0.01), and general health (0.44, p < 0.01). Fair to poor correlations were observed with vitality, social function, role emotional, and mental health domains of SF-36.
conclusionSC-FASH is recommended to evaluate the severity of hamstring muscle injuries and their impact on physical function and sports ability in Mainland China due to its good reliability, and validity.
