Study Overview
Brief Summary
Cognitive impairments occur frequently after stroke, and are associated with significant long-term activities of daily living (ADL) disability and poor quality of life. This research study will undertake an innovative approach addressing cognitive impairments, by examining a new patient-centered functionally-relevant rehabilitation intervention that teaches individuals with cognitive impairments to manage their deficits to reduce ADL disability.
Detailed Description
Cognitive impairments are characterized by problems sustaining attention in distracting conditions, shifting attention between different task demands, and using working memory to consistently execute intended actions, and as a result limit the ability to execute routine ADLs. Presently there are no interventions that have demonstrated robust effectiveness in reducing disability among individuals with cognitive impairments after stroke. Recent findings suggest that individuals with cognitive impairments may experience ADL disability in part because they have difficulty engaging in, and benefiting from rehabilitation programs as they are currently delivered. In other words, individuals with cognitive impairment, due to the nature of their impairments, have difficulty learning and applying adaptive strategies as they are currently provided during traditional rehabilitation training. Therefore, interventions that train individuals with cognitive impairments a new way to learn and apply adaptive strategies may help them benefit from rehabilitation programs and reduce long-term disability. Cognitive Orientation to daily Occupation Performance (CO-OP) is a strategy training approach that trains individuals to identify problems in the performance of daily activities, develop strategies to address these problems, and monitor their own performance in the course of their daily routines. Therefore, CO-OP teaches individuals to "take charge" of their rehabilitation, and develop adaptive behaviors to "work around" cognitive impairments to meet their goals. The proposed project examines whether CO-OP facilitates reductions in ADL disability and improvements in rehabilitation engagement among individuals with cognitive impairments after acute stroke.

Arms & Interventions
CO-OP
Cognitive Orientation to daily Occupational Performance (CO-OP) is a strategy training approach that trains individuals to identify problems in the performance of their daily activities, develop strategies to address these problems, and monitor their own performance in the course of their daily routines. Participants use a workbook to support their application of the strategy training.
Intervention: CO-OP (Behavioral)
Attention Control
The attention control intervention controls for the non-specific effects of strategy training. The therapists administer the standardized and dose-matched protocol, using scripted open-ended questions to facilitate participants' reflections on their rehabilitation activities and experiences. Participants complete a daily journal, merely reviewing their rehabilitation activities.
Intervention: Attention Control (Behavioral)
Outcomes
Primary Outcomes
Difference in Independence With Activities of Daily Living (Functional Independence Measure) Between Groups Over Time
Time Frame: Baseline, rehabilitation discharge, month 3, month 6
Difference between groups in mean scores (computed from Functional Independence Measure total scores) over time were examined with mixed effects models. The Functional Independence Measure contains 18 items with a total score ranging from 18-126 is obtained (18=complete dependence/total assistance with basic self-care and mobility activities; 126=complete independence with basic self-care and mobility activities). Total scores were calculated at baseline, rehabilitation discharge, month 3, and month 6 for each participant, and mean total scores were calculated fro each group at each time point.
Secondary Outcomes
- Difference in Executive Function- Inhibition, CWI (Color Word Interference Inhibition Scale)(Baseline, 3 months, 6 months)
- Differences in Apathy Symptoms Between Groups Over Time(Baseline, 3 months, 6 months)
- Difference in Executive Function - Cognitive Flexibility, CWI (Color Word Interference Switching Scale)(Baseline, 3 months, 6 months)
