Effect of Strategy Training on Self-Awareness of Deficits After Stroke.

ABSTRACT: IMPORTANCE:Self-awareness of deficits, or the ability to understand the effects of impairments on daily life, is often diminished after a stroke. Diminished self-awareness influences participation in rehabilitation and functional outcomes. OBJECTIVE:To examine whether self-awareness of deficits changed over time after a stroke (N = 43) and whether metacognitive strategy training (n = 21) resulted in improved self-awareness compared with direct skill training (n = 22). DESIGN:Secondary analysis of data collected from a randomized controlled trial. SETTING:Inpatient stroke rehabilitation. PARTICIPANTS:Adults with cognitive impairments after an acute stroke. INTERVENTION:Metacognitive strategy training is an approach in which clients are guided through a process of self-assessment and develop solutions for barriers to task performance. This approach was compared with direct skill training, in which the therapist provides specific instructions for task completion, removing the client-initiated assessment and problem-solving components. OUTCOMES AND MEASURES:Self-awareness measures included the Self-Regulation Skills Interview and Self-Awareness of Deficits Interview at baseline and 3 mo and 6 mo after the intervention. We used a one-way analysis of variance (ANOVA) to analyze change in self-awareness and a two-way ANOVA to examine differences between groups over time. RESULTS:There was a statistically significant and potentially meaningful difference over time in the self-awareness domain of strategy behavior, F(2) = 3.35, p = .039, but there were no differences in improvements between the metacognitive strategy and direct skill training groups. Conclusions and Relevance:Self-awareness warrants further investigation to determine whether it improves naturally over time or through both interventions after stroke. WHAT THIS ARTICLE ADDS:Self-awareness of deficits, and the use of strategies in particular, may improve in the early stages of stroke recovery, but the optimal approach for intervention remains unclear.

Project description:INTRODUCTION:Memory deficits characterize Alzheimer's dementia and the clinical precursor stage known as mild cognitive impairment. Nonpharmacologic interventions hold promise for enhancing functioning in these patients, potentially delaying functional impairment that denotes transition to dementia. Previous findings revealed that mnemonic strategy training (MST) enhances long-term retention of trained stimuli and is accompanied by increased blood oxygen level-dependent signal in the lateral frontal and parietal cortices as well as in the hippocampus. The present study was designed to enhance MST generalization, and the range of patients who benefit, via concurrent delivery of transcranial direct current stimulation (tDCS). METHODS:This protocol describes a prospective, randomized controlled, four-arm, double-blind study targeting memory deficits in those with mild cognitive impairment. Once randomized, participants complete five consecutive daily sessions in which they receive either active or sham high definition tDCS over the left lateral prefrontal cortex, a region known to be important for successful memory encoding and that has been engaged by MST. High definition tDCS (active or sham) will be combined with either MST or autobiographical memory recall (comparable to reminiscence therapy). Participants undergo memory testing using ecologically relevant measures and functional magnetic resonance imaging before and after these treatment sessions as well as at a 3-month follow-up. Primary outcome measures include face-name and object-location association tasks. Secondary outcome measures include self-report of memory abilities as well as a spatial navigation task (near transfer) and prose memory (medication instructions; far transfer). Changes in functional magnetic resonance imaging will be evaluated during both task performance and the resting-state using activation and connectivity analyses. DISCUSSION:The results will provide important information about the efficacy of cognitive and neuromodulatory techniques as well as the synergistic interaction between these promising approaches. Exploratory results will examine patient characteristics that affect treatment efficacy, thereby identifying those most appropriate for intervention.

Project description:Purpose: To investigate the effect of adding cognitive strategy training to task-specific training (TST), called Cognitive Oriented Strategy Training Augmented Rehabilitation (COSTAR), compared with TST on activity and participation for chronic stroke survivors in an outpatient occupational therapy settingMaterials and methods: We conducted an exploratory, single-blind, randomized controlled trial. Participants were randomized to TST or COSTAR protocol. Our primary outcomes measured activity and participation after stroke: the Stroke Impact Scale (SIS), Canadian Occupational Performance Measure (COPM), and Performance Quality Rating Scale (PQRS).Results: Forty-four participants were randomized. The COSTAR group had an attrition rate of 50% and an average of 9.8 of 12 sessions were completed; the TST group had an attrition rate of 25% and an average of 10.7 sessions were completed. Generally both groups improved on the majority of primary and secondary outcomes. There is little evidence to support a beneficial effect of COSTAR over TST for improvement of primary measures of activity performance or secondary measures.Conclusion: Negligible findings may be attributed to an inadvertent treatment group equivalency. Further, the research design did not allow for adequate measurement of the effect of each intervention on participants' ability to generalize learned skills.Implications for rehabilitationStroke rehabilitation is largely based upon the principles of task-specific training, which is associated with improvements in upper extremity motor performance; however, TST requires a heavy dosage and lacks generalization to untrained activities.Cognitive strategy use has been associated with improved generalization of treatment to untrained activities and novel contexts however, it is often not used in TST protocols.The results of this preliminary study found no clear advantage between task-specific training and strategy-adapted task-specific training on trained and untrained activities when both interventions targeted activity performance.Task-specific training, if focused at the activity performance level rather than the impairment reduction level, may have a stronger effect on improving in individual's ability to participate in everyday life activities even without the use of cognitive-strategies.Incorporating cognitive strategy-use into TST would likely produce the greatest effect on generalization and transfer of the treatment effects to other activities and contexts rather than solely on activity performance of trained activities.
