Abstract:
Background/Objective: This study aimed to translate the Fullerton Advanced Balance Scale (FAB) into Arabic and assess the instrument's reliability and validity. Methods: The study was carried out in two distinct stages: (i) the translation and adaptation process utilizing the 'forward-back' translation method and (ii) the psychometric evaluation of the Arabic version of the FAB-A among a sample of 68 older persons residing in the community. Results: The internal consistency of the FAB-A was excellent (Cronbach's alpha = 0.86). The Intraclass Correlation Coefficient (ICC) for the inter-rater tests (ICC = 0.96, p ≤ 0.001) and the intra-rater tests (ICC = 0.95, p ≤ 0.001) were excellent and significant. The scale showed a strong correlation with the Berg Balance Scale (r = 0.75). The sampling adequacy for factor analysis was proven by a Kaiser-Meyer-Olkin value of 0.84. The goodness of fit (GFI) statistics for the model were in the acceptable range (Chi-square/Degree of freedom (CMIN/DF) = 1.38, Goodness-of-Fit Index (GFI) = 0.88, Comparative Fit Index (CFI) = 0.95, Root Mean Square Error of Approximation (RMSEA) = 0.07). Conclusions: The FAB-A has demonstrated excellent psychometric qualities for measuring balance in older adults.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

Initiation of Translation
