Occupational therapy for cognitive impairment in stroke patients

BACKGROUND

Cognitive impairment is a frequent consequence of stroke and can impact on a person's ability to perform everyday activities. Occupational therapists use a range of interventions when working with people who have cognitive impairment poststroke. This is an update of a Cochrane Review published in 2010.

OBJECTIVES

To assess the impact of occupational therapy on activities of daily living (ADL), both basic and instrumental, global cognitive function, and specific cognitive abilities in people who have cognitive impairment following a stroke.

SEARCH METHODS

We searched the Cochrane Stroke Group Trials Register, CENTRAL, MEDLINE, Embase, four other databases (all last searched September 2020), trial registries, and reference lists.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials that evaluated an intervention for adults with clinically defined stroke and confirmed cognitive impairment. The intervention needed either to be provided by an occupational therapist or considered within the scope of occupational therapy practice as defined in the review. We excluded studies focusing on apraxia or perceptual impairments or virtual reality interventions as these are covered by other Cochrane Reviews. The primary outcome was basic activities of daily living (BADL) such as dressing, feeding, and bathing. Secondary outcomes were instrumental ADL (IADL) (e.g. shopping and meal preparation), community integration and participation, global cognitive function and specific cognitive abilities (including attention, memory, executive function, or a combination of these), and subdomains of these abilities. We included both observed and self-reported outcome measures.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies that met the inclusion criteria, extracted data, and assessed the certainty of the evidence. A third review author moderated disagreements if consensus was not reached. We contacted trial authors for additional information and data, where available. We assessed the certainty of key outcomes using GRADE.  MAIN RESULTS: We included 24 trials from 11 countries involving 1142 (analysed) participants (two weeks to eight years since stroke onset). This update includes 23 new trials in addition to the one study included in the previous version. Most were parallel randomised controlled trials except for one cross-over trial and one with a two-by-two factorial design. Most studies had sample sizes under 50 participants. Twenty studies involved a remediation approach to cognitive rehabilitation, particularly using computer-based interventions. The other four involved a compensatory and adaptive approach. The length of interventions ranged from 10 days to 18 weeks, with a mean total length of 19 hours. Control groups mostly received usual rehabilitation or occupational therapy care, with a few receiving an attention control that was comparable to usual care; two had no intervention (i.e. a waiting list). Apart from high risk of performance bias for all but one of the studies, the risk of bias for other aspects was mostly low or unclear.  For the primary outcome of BADL, meta-analysis found a small effect on completion of the intervention with a mean difference (MD) of 2.26 on the Functional Independence Measure (FIM) (95% confidence interval (CI) 0.17 to 4.22; P = 0.03, I2 = 0%; 6 studies, 336 participants; low-certainty evidence). Therefore, on average, BADL improved by 2.26 points on the FIM that ranges from 18 (total assist) to 126 (complete independence). On follow-up, there was insufficient evidence of an effect at three months (MD 10.00, 95% CI -0.54 to 20.55; P = 0.06, I2 = 53%; 2 studies, 73 participants; low-certainty evidence), but evidence of an effect at six months (MD 11.38, 95% CI 1.62 to 21.14, I2 = 12%; 2 studies, 73 participants; low-certainty evidence). These differences are below 22 points which is the established minimal clinically important difference (MCID) for the FIM for people with stroke. For IADL, the evidence is very uncertain about an effect (standardised mean difference (SMD) 0.94, 95% CI 0.41 to 1.47; P = 0.0005, I2 = 98%; 2 studies, 88 participants). For community integration, we found insufficient evidence of an effect (SMD 0.09, 95% CI -0.35 to 0.54; P = 0.68, I2 = 0%; 2 studies, 78 participants). There was an improvement of clinical importance in global cognitive functional performance after the intervention (SMD 0.35, 95% CI 0.16 to 0.54; P = 0.0004, I2 = 0%; 9 studies, 432 participants; low-certainty evidence), equating to 1.63 points on the Montreal Cognitive Assessment (MoCA) (95% CI 0.75 to 2.52), which exceeds the anchor-based MCID of the MoCA for stroke rehabilitation patients of 1.22. We found some effect for attention overall (SMD -0.31, 95% CI -0.47 to -0.15; P = 0.0002, I2 = 20%; 13 studies, 620 participants; low-certainty evidence), equating to a difference of 17.31 seconds (95% CI 8.38 to 26.24), and for executive functional performance overall (SMD 0.49, 95% CI 0.31 to 0.66; P < 0.00001, I2 = 74%; 11 studies, 550 participants; very low-certainty evidence), equating to 1.41 points on the Frontal Assessment Battery (range: 0-18). Of the cognitive subdomains, we found evidence of effect of possible clinical importance, immediately after intervention, for sustained visual attention (moderate certainty) equating to 15.63 seconds, for working memory (low certainty) equating to 59.9 seconds, and thinking flexibly (low certainty), compared to control.

AUTHORS' CONCLUSIONS

The effectiveness of occupational therapy for cognitive impairment poststroke remains unclear. Occupational therapy may result in little to no clinical difference in BADL immediately after intervention and at three and six months' follow-up. Occupational therapy may slightly improve global cognitive performance of a clinically important difference immediately after intervention, likely improves sustained visual attention slightly, and may slightly increase working memory and flexible thinking after intervention. There is evidence of low or very low certainty or insufficient evidence for effect on other cognitive domains, IADL, and community integration and participation.  Given the low certainty of much of the evidence in our review, more research is needed to support or refute the effectiveness of occupational therapy for cognitive impairment after stroke. Future trials need improved methodology to address issues including risk of bias and to better report the outcome measures and interventions used.

Examining components of community psychosocial stroke interventions using concept mapping

BACKGROUND

Stroke impacts psychosocial well-being and engagement in occupation. Psychosocial interventions reduce depression and anxiety but may not impact occupation. Knowledge of key processes and components of community psychosocial stroke interventions can inform future intervention development.

AIM/OBJECTIVE(S)

To determine the essential elements common to three psychosocial interventions for stroke survivors.

MATERIAL(S) AND METHOD(S)

Concept maps were created for three community psychosocial stroke interventions based on published literature and communication with researchers who tested the intervention with stroke survivors. The concept maps were then compared to identify common elements. Ongoing communication with researchers ensured accurate representation of each respective intervention.

RESULTS

Similarities in intervention processes and components included support for autonomy; individualized information exchange; coping, life skill development and adaptation support; competence development; and the incorporation of goals. Differences included intervention delivery (individual versus group), and the avenues in which psychosocial needs are addressed (occupation versus dialogue).

CONCLUSIONS

Concept mapping identified similarities among the three interventions that can be best understood using self-determination theory. Clinicians may utilize findings revealed in the process to inform evidence-based psychosocial stroke interventions.

SIGNIFICANCE

Knowledge of key 'active ingredients' for psychosocial community stroke interventions, can be used to guide clinical reasoning and inform development of interventions.

Effectiveness of a tele-rehabilitation intervention to improve performance and reduce morbidity for people post hip fracture - study protocol for a randomized controlled trial

BACKGROUND

Most surviving hip-fracture patients experience reduced mobility and lose some of their functional ability, which increases the risk of complications and rehospitalization. Post-discharge transitional programs to reduce readmissions and disabilities have shown some success. Telerehabilitation refers to the use of technologies to provide rehabilitation services to people in their homes. Considering the need for long-term follow-up care for people with hip fracture, in-home telerehabilitation could increase independence, decrease hospital stays and reduce the burden for caregivers. The objective of this study is to investigate the effectiveness of an intervention program based on telerehabilitation on activities of daily living (ADL), quality of life (QOL), depression and burden on caregivers compared to face-to-face home visits and usual care of community-dwelling older adults after hip fracture.

METHODS/DESIGN

This will be a three-armed randomized control trial (RCT) including pre/post intervention and follow-up. The trial will include 90 older people with hip fractures who will be randomly assigned to a telerehabilitation group (N = 30), face-to-face visits (N = 30) and a control group. The aim of the intervention is to improve the transition from rehabilitation units to community dwelling. It will include 10 videoconferencing/ face-to-face sessions from an occupational therapist in the presence of the primary caregiver. Each session will be utilized to guide the participants to achieve their self-identified goals, focusing on problem-solving for daily life situations and on the ability to implement the discussed strategies for a variety of activities. Outcome measures include Functional Independence Measure (FIM) for evaluation of ADL, SF-12 for evaluation of Health-related QOL, The Geriatric Depression Scale (GDS) and The Zarit Caregiver Burden Scale. Data will be analyzed using Repeated measures MANOVA.

DISCUSSION

The current study will enable the cost-effectiveness examination of a suggested rehabilitation service based on available technology. The proposed intervention will increase accessibility of in-home rehabilitation services, improve function and health, and reduce economic burden.

The implications of the Canadian Stroke Best Practice Recommendations for design and allocation of rehabilitation after hospital discharge: a problematization

Introduction: Implementation of the Canadian Stroke Best Practice Recommendations has improved inpatient rehabilitation. As attention is turned to the design and allocation of rehabilitation after hospitalization, examination of their implications for post-discharge rehabilitation could help optimize service planningMethods: Critical discourse analysis modeled on Alvesson and Sandberg's method of problematization was conducted to determine how the Canadian Stroke Best Practice Recommendations envision and shape post-discharge rehabilitation, and identify any tensions and potential ways to resolve them.Results: Within the Canadian Stroke Best Practice Recommendations post-discharge rehabilitation is implicitly viewed as a continuation of inpatient rehabilitation. Rehabilitation is largely envisioned as a set of biomedical procedures aimed at normalization through correction of impairment. There is potential tension between this implicit goal and the explicit goal of providing patient and family-centered care and promoting reengagement in valued activities and roles.Conclusion: An alternate vision of post-discharge rehabilitation could help resolve this tension. Post-discharge rehabilitation could be envisioned as a self-management intervention. Rather than primarily an expert-driven process of measuring impairment and applying procedures aimed at normalization, rehabilitation would be considered facilitation of self-management with the goal of reengaging in forms of participation that comprise a satisfying life.Implications for RehabilitationImplicit assumptions within best practice guidelines powerfully influence recommendations. These ideas are difficult to examine because they seem self-evident.Implicit assumptions in the Canadian Stroke Best Practice Guidelines envision post-discharge stroke rehabilitation as an expert-driven, impairment-focused biomedical procedure.This biomedical image makes it difficult to provide care that meets the guideline's explicit goals of client- and family-centeredness.Reimagining post-discharge stroke rehabilitation as a chronic self-care management intervention aimed at developing a satisfying life after stroke could improve patient care.

Goal setting dynamics that facilitate or impede a client-centered approach

BACKGROUND

Client-centred goal setting is central to the process of enabling occupation. Yet, there are multiple barriers to incorporating client-centred goal setting in practice. We sought to determine what might facilitate or impede the formation of client-centred goals in a context highly supportive of client-centred goal setting Methods: We used conversational analysis to examine goal-setting conversations that took place during a pilot trial of Occupational Performance Coaching for stroke survivors. Twelve goal-setting sessions were purposively selected, transcribed, and analyzed according to conventions for conversation analysis.

RESULTS

Two main types of interactions were observed: introductory actions and goal selection actions. Introductory actions set the context for goal setting and involved sharing information and seeking clarification related to goal requirements and clients' occupational performance competencies. Goal selection actions were a series of interactions whereby the goals were explored, endorsed or dropped.

CONCLUSION

Client-centred occupational performance goals may be facilitated through placing goal-setting in the context of life changes and lifelong development of goals, and through listening to clients' stories. Therapists may improve consistency in adoption of client-suggested goals through clarifying meaning attached to goals and being attuned to power dynamics and underlying values and beliefs around risk and goal attainability.

Occupational Therapy Practitioners' Perspectives of Mental Health Practices With Clients in Stroke Rehabilitation

Following a stroke, depression and anxiety may negatively affect recovery and decrease quality of life. Occupational therapy (OT) practitioners are distinctly qualified to address both the physical and psychosocial sequelae of a stroke, including clients' mental and emotional health. This study explored the ways in which OT practitioners address the mental health needs of clients post stroke. A sequential explanatory mixed-methods design was used to collect both survey and focus group data. In all, 754 OT practitioners across the United States completed an online survey, and 10 practitioners participated in focus groups. Practitioners considered their clients' mental health needs to be a priority (68.17%); however, only 56.64% were satisfied with the care they provided related to mental and emotional health. They identified barriers that included limited time, increased productivity standards, expectations related to physical recovery, and poor educational preparation. Practitioners are motivated to improve their provision of mental health services to clients post stroke. To address the conflict between practice realities and professional values, education programs should better integrate curricular components that focus on physical and mental health.

Occupational Performance Coaching for Stroke Survivors: A Pilot Randomized Controlled Trial

OBJECTIVE

We examined the feasibility of study procedures and explored the potential efficacy of Occupational Performance Coaching for stroke survivors (OPC-Stroke), an intervention designed to improve participation after stroke.

METHOD

In this pilot randomized controlled trial, 21 participants were randomized to receive the intervention or usual care. Recruitment, retention, and outcome completion rates were calculated. Direction of change and effect sizes were examined for the outcomes of participation, goal performance and satisfaction, goal self-efficacy, emotional well-being, and cognition.

RESULTS

Rates of recruitment (66%) and retention (81%) were satisfactory. Participation scores improved for both groups with different trajectories. Results showed a moderate effect of OPC-Stroke for goal performance (η²_partial d = .075) and satisfaction (η²_partial d = .078) and a large effect for cognition (η²_partial d = .167). Other outcome measures did not change as expected.

CONCLUSION

Study procedures were generally feasible. Preliminary findings support testing to examine the efficacy of OPC-Stroke.

Occupational therapy for adults with problems in activities of daily living after stroke

BACKGROUND

A stroke occurs when the blood supply to part of the brain is cut off. Activities of daily living (ADL) are daily home-based activities that people carry out to maintain health and well-being. ADLs include the ability to: eat and drink unassisted, move, go to the toilet, carry out personal hygiene tasks, dress unassisted, and groom. Stroke causes impairment-related functional limitations that may result in difficulties participating in ADLs independent of supervision, direction, or physical assistance.For adults with stroke, the goal of occupational therapy is to improve their ability to carry out activities of daily living. Strategies used by occupational therapists include assessment, treatment, adaptive techniques, assistive technology, and environmental adaptations. This is an update of the Cochrane review first published in 2006.

OBJECTIVES

To assess the effects of occupational therapy interventions on the functional ability of adults with stroke in the domain of activities of daily living, compared with no intervention or standard care/practice.

SEARCH METHODS

For this update, we searched the Cochrane Stroke Group Trials Register (last searched 30 January 2017), the Cochrane Controlled Trials Register (The Cochrane Library, January 2017), MEDLINE (1946 to 5 January 2017), Embase (1974 to 5 January 2017), CINAHL (1937 to January 2017), PsycINFO (1806 to 2 November 2016), AMED (1985 to 1 November 2016), and Web of Science (1900 to 6 January 2017). We also searched grey literature and clinical trials registers.

SELECTION CRITERIA

We identified randomised controlled trials of an occupational therapy intervention (compared with no intervention or standard care/practice) where people with stroke practiced activities of daily living, or where performance in activities of daily living was the focus of the occupational therapy intervention.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials, assessed risk of bias, and extracted data for prespecified outcomes. The primary outcomes were the proportion of participants who had deteriorated or were dependent in personal activities of daily living and performance in activities of daily living at the end of follow-up.

MAIN RESULTS

We included nine studies with 994 participants in this update. Occupational therapy targeted towards activities of daily living after stroke increased performance scores (standardised mean difference (SMD) 0.17, 95% confidence interval (CI) 0.03 to 0.31, P = 0.02; 7 studies; 749 participants; low-quality evidence) and reduced the risk of poor outcome (death, deterioration or dependency in personal activities of daily living) (odds ratio (OR) 0.71, 95% CI 0.52 to 0.96; P = 0.03; 5 studies; 771 participants; low-quality evidence). We also found that those who received occupational therapy were more independent in extended activities of daily living (OR 0.22 (95% CI 0.07 to 0.37); P = 0.005; 5 studies; 665 participants; low-quality evidence). Occupational therapy did not influence mortality (OR: 1.02 (95% CI 0.65 to 1.61); P = 0.93; 8 studies; 950 participants), or reduce the combined odds of death and institutionalisation (OR 0.89 (95% CI 0.60 to 1.32); P = 0.55; 4 studies; 671 participants), or death and dependency (OR 0.89 (95% CI 0.64 to 1.23); P = 0.47; 4 trials; 659 participants). Occupational therapy did not improve mood or distress scores (OR 0.08 (95% CI -0.09 to 0.26); P = 0.35; 4 studies; 519 participants; low-quality evidence). There were insufficient data to determine the effects of occupational therapy on health-related quality of life. We found no studies of consenting carers prior to study participation and therefore there were no carer-related outcomes in our review. There were insufficient data to determine participants' and carers' satisfaction with services.Using GRADE, the quality of evidence was low. The major limitation was the number of studies at unclear risk of selection bias and an inevitable high risk of performance and detection bias, as both participants and occupational therapists could not be blinded to the intervention. In addition, there was a sparseness of data for our outcomes of interest and we downgraded the quality of our evidence for these reasons.

AUTHORS' CONCLUSIONS

We found low-quality evidence that occupational therapy targeted towards activities of daily living after stroke can improve performance in activities of daily living and reduce the risk of deterioration in these abilities. Because the included studies had methodological flaws, this research does not provide a reliable indication of the likely effect of occupational therapy for adults with stroke.

Self-regulation workshop and Occupational Performance Coaching with teachers: A pilot study

BACKGROUND

Teachers' occupational role and performance can be undermined when working with students with disruptive classroom behaviours.

PURPOSE

This pilot study aimed to explore the impact of school-based occupational therapy intervention on teachers' classroom management self-efficacy and perceived performance/satisfaction in their management of students with disruptive behaviours.

METHOD

This pilot study used a multiple-case replication study design. A cohort of regular classroom elementary school teachers (n = 11) participated in a 1-day workshop on sensorimotor strategies for supporting student self-regulation followed by eight individual sessions of Occupational Performance Coaching (OPC). Measurement tools were the Canadian Occupational Performance Measure, Goal Attainment Scaling (GAS), and Teachers' Self-Efficacy Scale-Classroom Management.

FINDINGS

Improvement in teachers' perception of performance, satisfaction, and classroom management was seen. GAS showed clinically significant improvement. Improvements were sustained at 7 weeks follow-up.

IMPLICATIONS

Preliminary results support the use of sensorimotor education combined with OPC to enable teachers' occupational performance.
