The trunk control: Which scale is the best in very acute stroke patients?

Background: It is important to evaluate trunk control, given that it is one of the indicators of adequate functional and motor recovery in patients following a stroke. The assessment should be feasible and adequate in clinical conditions in the acute phase. Objectives: The aim of this study was to detect the most appropriate scale used for trunk control assessment in very acute stroke patients in terms of time and ease of implementation. Methods: Sixty-five patients with very acute stroke were included in the study. The patients were assessed with the Trunk Impairment Scale-1 (VTIS), the Trunk Impairment Scale-2 (FTIS), the Motor Assessment Scale trunk subscale (T-MAS) and the Trunk Control Test (TCT), and Functional Impairment Measure (FIM). Floor/ceiling effects, reliability, validity responsiveness of all trunk control scales analyzed. The correlation between all scales and FIM were calculated. Results: All scales had similar reliability, responsiveness and construct validity level. T-MAS and TCT were more advantageous than other scales according to time. TCT and VTIS showed floor effect. The best predictive validity values were observed for the T-MAS and TCT. Conclusions: Four scales investigated in this study can also be used to evaluate the patients with very acute stroke. On the other hand, the advantages and disadvantages of the scales should be thoroughly assessed and researchers can use one of four scales considering their aim, patient populations and clinical characteristics of patients.
