Correlation of visual analogue scale foot and ankle (VAS-FA) to AOFAS score in malleolar fractures using Indian language questionnare

Reliability and validity of the Finnish version of the Visual Analogue Scale Foot and Ankle (VAS-FA)

“…The authors' linguistic validation of the VAS-FA into Finnish found no cultural differences in health, disease, or operational environment in the adaptation process between the original and the translated version. Previously published translation and validation reports of the VAS-FA to another language have not specified if any linguistic or cultural changes were made in the translation process [3,4].…”

“…The authors estimated the absolute reliability of the total VAS-FA at 16 (CI, [13][14][15][16][17][18][19][20][21]. Previous psychometric studies of the VAS-FA have not estimated the absolute reliability [2][3][4]9].…”

“…The VAS-FA score also correlated significantly with the 15D Mobility dimension, supporting the construct validity of the VAS-FA instrument for functional assessment. Nair et al found a strong correlation between the VAS-FA and the American Orthopedic Foot & Ankle Society (AOFAS) score in their analysis of results in a cohort of 50 malleolar fracture patients [4]. Furthermore, Angthong et al reported a significant correlation of the VAS-FA score and the SF-36 Physical Functioning scale (r = 0.55) [3].…”

“…The authors recruited a representative population of foot and ankle patients that compared favourably with published reports of VAS-FA psychometrics [2][3][4]. The authors used two validated PROMs, of which the other was a well-recognized foot and ankle tool (LEFS) [12,13], to assess the convergent validity of the Finnish VAS-FA.…”

“…These instruments include the English version of the Visual Analogue Scale Foot and Ankle (VAS-FA) [2]. The VAS-FA has been further validated in Thai and Indian languages (Malayalam) [3,4].…”
