Trunk performance after stroke: an eye-catching predictor of functional outcome

Trunk performance after stroke: an eye-catching predictor of functional outcome
Trunk performance after stroke: an eye-catching predictor of functional outcome
Background and Purpose: trunk performance is an important predictor of functional outcome after stroke. However, the percentage of explained variance varies considerably between studies. This may be explained by the stroke population examined, the different scales used to assess trunk performance, and the time points used to measure outcome. The aim of this multi-centre study was to examine the predictive validity of the Trunk Impairment Scale (TIS) and its subscales when predicting Barthel index score at six months after stroke.
Methods: a total of 102 subjects were recruited in three European rehabilitation centres. Participants were assessed on admission (median time since stroke onset was 20 days) and six months after stroke. Correlation analysis and forward stepwise multiple regression analysis were used to model outcome.
Results: the best predictors of Barthel index scores at six months after stroke were total TIS score (partial R² = 0.52, p<.0001) and static sitting balance subscale score (partial R² = 0.50, p<.0001) on admission. The TIS score on admission and its static sitting balance subscale were stronger predictors of the Barthel index score at six months than the Barthel index score on admission itself.
Conclusions: this study emphasizes the importance of trunk performance, especially static sitting balance, when predicting functional outcome after stroke. The TIS is recommended as a prediction instrument in the rehabilitation setting when considering the prognosis of stroke patients. Future studies should address the evolution of trunk performance over time and the evaluation of treatment interventions to improve trunk performance.

Abstract

Background and Purpose: trunk performance is an important predictor of functional outcome after stroke. However, the percentage of explained variance varies considerably between studies. This may be explained by the stroke population examined, the different scales used to assess trunk performance, and the time points used to measure outcome. The aim of this multi-centre study was to examine the predictive validity of the Trunk Impairment Scale (TIS) and its subscales when predicting Barthel index score at six months after stroke.
Methods: a total of 102 subjects were recruited in three European rehabilitation centres. Participants were assessed on admission (median time since stroke onset was 20 days) and six months after stroke. Correlation analysis and forward stepwise multiple regression analysis were used to model outcome.
Results: the best predictors of Barthel index scores at six months after stroke were total TIS score (partial R² = 0.52, p<.0001) and static sitting balance subscale score (partial R² = 0.50, p<.0001) on admission. The TIS score on admission and its static sitting balance subscale were stronger predictors of the Barthel index score at six months than the Barthel index score on admission itself.
Conclusions: this study emphasizes the importance of trunk performance, especially static sitting balance, when predicting functional outcome after stroke. The TIS is recommended as a prediction instrument in the rehabilitation setting when considering the prognosis of stroke patients. Future studies should address the evolution of trunk performance over time and the evaluation of treatment interventions to improve trunk performance.
