Objective:
To examine the utility of decision analysis methods for examining the dynamic nature of impairment-activity interactions following stroke.
Design:
Decision analyses (Chi-squared Automatic Interaction Detector) of a prospective cohort study.
Setting:
Community and institutional settings based on the location of participants three months after stroke.
Participants:
Individuals were recruited from consecutive admissions to a regional academic health center and were assessed three months after stroke (N= 67).
Main Outcome Measures:
Neurological impairment was measured with the National Institutes of Health Stroke Scale (NIHSS). Mobility, self-care and instrumental activities of daily living (instrumental ADL) performance were assessed with a performance observation measure, the Performance Assessment of Self-care Skills (PASS). Decision analysis methods were used to examine interactions between neurological impairments and activity outcomes.
Results:
Unique neurological impairments were associated with each activity outcome (bowel and bladder urgency interacted with mobility; hand function interacted with self-care; mental functions interacted with instrumental ADL), and these findings are supported by previous studies. The predictive validity of mobility and self-care analyses was stronger than the instrumental ADL analyses.
Conclusions:
Decision analysis methods show promise for understanding dynamic impairment--activity interactions. This understanding may enhance methods for informing rehabilitation decisions.
