Descriptive characteristics as potential predictors of outcomes following constraint-induced movement therapy for people after stroke.

BACKGROUND AND PURPOSE

Limited evidence exists regarding the characteristics of people who benefit most from constraint-induced movement therapy (CIMT). This study's purpose was to investigate 6 potential descriptors in predicting CIMT outcomes.

SUBJECTS

The participants were a convenience sample (N=55) of people who were more than 6 months poststroke.

METHODS

The Wolf Motor Function Test (WMFT) and the Motor Activity Log amount scale (MALa) were used to assess outcomes for CIMT. The potential predictors (side of stroke, time since stroke, hand dominance, age, sex, and ambulatory status) were entered into a linear regression model using stepwise entry, with simultaneous entry of the dependent variables' pretest scores as the covariate.

RESULTS

Age was the only significant predictor of the 6 potential predictors in the model and was predictive only of MALa scores. None of the independent variables showed a predictive relationship with the WMFT.

DISCUSSION AND CONCLUSION

Although age was the only significant predictor, an equally strong finding in this study was that side of stroke, chronicity, hand dominance, sex, and ambulatory status were not found to be predictors at the follow-up session. This finding emphasizes the importance of not excluding people from CIMT based on these predictors.
