Establishing the Turkish version of the SIGAM mobility scale, and determining its validity and reliability in lower extremity amputees

AbstractPurpose: The aim of this study is to adapt the Special Interest Group in Amputee Medicine (SIGAM) mobility scale to Turkish, and to test its validity and reliability in lower extremity amputees.Material and methods: Adaptation of the scale into Turkish was performed by following the steps in American Association of Orthopedic Surgeons (AAOS) guideline. Turkish version of the scale was tested twice on 109 patients who had lower extremity amputations, at hours 0 and 72. The reliability of the Turkish version was tested for internal consistency and test–retest reliability. Structural validity was tested using the “scale validity” method. For this purpose, the scores of the Short Form-36 (SF-36), Functional Ambulation Scale (FAS), Get Up and Go Test, and Satisfaction with the Prosthesis Questionnaire (SATPRO) were calculated, and analyzed using Spearman’s correlation test.Results: Cronbach’s alpha coefficient was 0.67 for the Turkish version of the SIGAM mobility scale. Cohen's kappa coefficients were...
