Effects of the CO-OP Approach in Addressing the Occupational Performance of Adults With Stroke: A Systematic Review

BACKGROUND

Stroke is the third leading cause of permanent disability worldwide. It is associated with difficulties in occupational performance, an area targeted by the Cognitive Orientation to daily Occupational Performance (CO-OP).

OBJECTIVE

To investigate the evidence available for the effectiveness of the CO-OP in addressing adults' performance of activities of daily living.

DATA SOURCES

Randomized controlled trials (RCTs) or pilot RCTs of the CO-OP written in English and published through December 2021 were retrieved from PubMed, SCOPUS, ScienceDirect, OTseeker, and EBSCO.

STUDY SELECTION AND DATA COLLECTION

The studies' participants were adults with stroke, evaluated on occupational performance before and after CO-OP administration. The American Occupational Therapy Association Evidence-Based Practice Project methodology was followed. Quality appraisal was conducted using the Cochrane Collaboration's Risk of Bias 2 tool.

RESULTS

Four RCTs and 3 pilot RCTs met the inclusion criteria. Inconsistent results are presented for trained and untrained goals, with the last ones being scarcely investigated.

LIMITATIONS

The limited number of studies, combined with the methodological limitations observed, did not allow for definite conclusions to be reached.

CONCLUSIONS AND RELEVANCE

The CO-OP is a promising client-centered, occupation-based approach, but future adequately powered studies addressing the potential for generalization are needed. Plain-Language Summary: The Cognitive Orientation to daily Occupational Performance is a relatively new treatment method that uses cognitive techniques to guide patients into discovering ways to perform activities of daily living independently. This systematic review presents the available evidence regarding CO-OP's effectiveness when used with adults after stroke. The findings showed that CO-OP has a positive impact in this population, but further research is needed to reach more concrete conclusions. Stroke patients may benefit from CO-OP because it can be a cost-effective, short-duration, task-oriented treatment.

Effects of Cognitive Orientation to Daily Occupational Performance and Conductive Education Treatment Approaches on Fine Motor Skills, Activity and Participation Limitations in Children with Down Syndrome: A Randomised Controlled Trial

This study aiming to compare the effectiveness of Cognitive Orientation to Daily Occupational Performance (CO-OP) and Conductive Education (CE) approaches on motor skills, activity limitation and participation restrictions in children with Down Syndrome (DS). Twelwe children were randomly assigned into two groups. Twelve-week CO-OP or CE intervention (period-1) followed by a 12-week washout period. Same interventions were crossed over for another 12 weeks (period-2). The Performance Quality Rating Scale (PQRS), Canadian Occupational Performance Measure (COPM) and the Bruininks Oseretsky Test of Motor Proficiency Second Edition-Brief Form (BOT2-BF) were used for outcome measurements. CO-OP was effective in the improvement of task-specific activity performance, while both approaches have similar effects on the improvement of perceived performance, satisfaction, and motor skills performance.

Feasibility of Augmenting Cognitive Strategy Training With Non-Invasive Brain Stimulation

Many individuals post-stroke have difficulty identifying if or how they can continue performing meaningful daily life tasks. The objective of this study was to evaluate the feasibility of metacognitive strategy training (MCST) and transcranial direct current stimulation (tDCS) in chronic stroke. A case series design was used. Participants completed 12 intervention sessions over 4 weeks consisting of 20 min of tDCS and 45 min of MCST to address occupational performance goals. Feasibility outcomes of acceptability and safety/tolerability were evaluated and measures of occupational performance were administered pre- and post-intervention. Participants perceived the intervention to be highly acceptable and relevant to their needs. Large improvements were observed for performance and satisfaction with goals trained (Hedge's g = 2.07 and 2.11, respectively) and untrained (Hedge's g = 1.25 and 1.43, respectively) within the intervention. An intervention combining MCST with tDCS was feasible to administer and positively received by stakeholders; further research is warranted.

Effectiveness of CO-OP group intervention for children with developmental coordination disorder: single-case experimental design study protocol

INTRODUCTION

With the Cognitive Orientation to daily Occupational Performance (CO-OP) approach, children with developmental coordination disorder learn to use a problem-solving strategy to deal with their motor difficulties and perform daily activities of their choice. Therapists use guided discovery to enable children to find their own solutions. Although CO-OP is recommended in a group setting, studies are needed to support its effectiveness.

METHODS AND ANALYSIS

A single-case study design with multiple baselines across participants and four systematic replications will be used. In each of the five groups, four children (aged 8-12 years) will be randomly included at the baseline. The baseline includes 5-8 measurements, and the CO-OP intervention stage is comprised of 10 sessions. The follow-up stage includes five measurements. Prior to baseline, each child in each of the five groups will choose five activities of which three will be carried out during the intervention sessions. Children's performance in each of these activities will be scored using the Performance Quality Rating Scale (PQRS) as the main measure. Three secondary measures will be collected: perceived activity performance using the Canadian Occupational Performance Measure, quality of life using the Kidscreen-27 and spontaneous motor rhythm using a computerised typing task. Graphed data will be analysed visually at the individual level with the Visual Aid Implying an Objective Rule (VAIOR) protocol which provides a colour code based on the level and trend of two consecutive phases, facilitating an objective visual analysis. Statistics will be performed for PQRS scores at the individual level and at the group level.

ETHICS AND DISSEMINATION

The protocol has been approved by the Comité de protection des personnes Sud-Est I (CPP 2021070) and the Comité d'éthique de la recherche avec les êtres humains de l'Université du Québec à Trois-Rivières (CER-22-294-07.03). Results will be published in a peer-reviewed scientific journal.

Assessing Older Adults' Functional Visual Performance Using the Performance Quality Rating Scale

Visual impairment has distinct impacts on the activities of older adults. Quantifying the functional impact of visual loss would facilitate targeted rehabilitation. The objectives of this study were to: (1) develop an observational assessment of the functional visual performance of older adults using the Performance Quality Rating Scale (PQRS); (2) test the feasibility and inter-rater agreement in a pilot sample of older adults with visual impairment. A convenience sample of older adults with vision loss (N = 20) performed seven pre-selected activities. Performance was videoed (N = 126 videos) and rated by two raters using specific operational definitions. All participants completed the seven activities with the given resources and 90% of videos were successfully rated using the developed PQRS. Inter-rater agreement was substantial (weighted Kappa = 0.71; 95% confidence interval [CI] = [0.64, 0.79]) for all activities. The developed PQRS for functional vision is feasible, with substantial inter-rater agreement, to assess functional vision of older adults in an outpatient setting.

Efficacy and Feasibility of the CO-OP Approach in Parkinson's Disease: RCT Study Protocol

Background. Parkinson's disease (PD) leads to cognitive dysfunction which limits participation and occupational performance. Cognitive Orientation to Daily Occupational Performance (CO-OP) approach is effective in other adult neurological populations and warrants investigation in PD. Purpose. To describe a study protocol evaluating the preliminary efficacy and feasibility of CO-OP approach in PD. Method. A randomised controlled trial (RCT) with adults with PD was assigned to either: CO-OP training-intensive (CO-OP-I, 20 sessions) or waitlist control (WLC) followed by CO-OP-standard (CO-OP-S, 10 sessions). Outcomes. Occupational performance and satisfaction of adults with PD in chosen goals. Measures will be obtained at baseline, post-intervention, and 3-month follow-up. Implications. As the first RCT focused on CO-OP in PD, this trial will provide evidence for the potential of this approach in PD and lay the groundwork for future large-scale trials. Trial Registration. Australian New Zealand Clinical Trials registry, ACTRN12621001483842. Registered November 1, 2021; retrospectively registered 3 months after commencement.

Feasibility of using the Cognitive Orientation to daily Occupational Performance in a population of Danish stroke survivors: Adaptation and study protocol

BACKGROUND

A need was identified for an occupational therapy intervention for stroke survivors in a Danish municipal healthcare setting with emphasis on its ability to transfer and generalise what is learned in occupational therapy to everyday life post therapy. Being a possible candidate, the Cognitive Orientation to daily Occupational Performance (CO-OP) approach needed to be adapted to the target group and context, and its feasibility needed examination regarding reach, dose, intervention components, fidelity, perceived value, benefits, harms, and potential outcomes.

AIM

To adapt the CO-OP to a Danish healthcare setting and present a protocol for examining its feasibility.

MATERIAL AND METHODS

The Adapting interventions to new contexts (ADAPT) guidance was followed to (1) Assess the rationale for intervention and consider intervention-context fit, (2) Plan and undertake adaptations, and (3) Plan a feasibility study.

RESULTS

Intervention materials and procedures were translated and adapted for home-based occupational therapy with people in the subacute phase of stroke. A protocol was developed to examine feasibility aspects. Quantitative and qualitative evaluations were planned and measurements chosen.

CONCLUSIONS AND SIGNIFICANCE

The planned feasibility study will contribute to further developing and refining the intervention before performing a possible large-scale effectiveness study.

Occupational Therapy Practice Guidelines for Adults With Stroke

IMPORTANCE

Stroke is a leading cause of disability. Occupational therapy practitioners ensure maximum participation and performance in valued occupations for stroke survivors and their caregivers.

OBJECTIVE

These Practice Guidelines are meant to support occupational therapy practitioners' clinical decision making when working with people after stroke and their caregivers.

METHOD

Clinical recommendations were reviewed from three systematic review questions on interventions to improve performance and participation in daily activities and occupations and from one question on maintaining the caregiving role for caregivers of people after stroke.

RESULTS

The systematic reviews included 168 studies, 24 Level 1a, 90 Level 1b, and 54 Level 2b. These studies were used as the basis for the clinical recommendations in these Practice Guidelines and have strong or moderate supporting evidence.

CONCLUSIONS AND RECOMMENDATIONS

Interventions with strong strength of evidence for improving performance in activities of daily living and functional mobility include mirror therapy, task-oriented training, mental imagery, balance training, self-management strategies, and a multidisciplinary three-stages-of-care rehabilitation program. Constraint-induced therapy has strong strength of evidence for improving performance of instrumental activities of daily living. Moderate strength of evidence supported cognitive-behavioral therapy (CBT) to address balance self-efficacy, long-term group intervention to improve mobility in the community, and a wearable upper extremity sensory device paired with training games in inpatient rehabilitation to improve social participation. Practitioners should incorporate problem-solving therapy in combination with CBT or with education and a family support organizer program. What This Article Adds: These Practice Guidelines provide a summary of strong and moderate evidence for effective interventions for people with stroke and for their caregivers.

Cognitive orientation to daily occupational performance (CO-OP) approach as telehealth for a child with developmental coordination disorder: a case report

Aim

This study aimed to propose a possible interventional form of occupational therapy through a case study report of the applied Cognitive Orientation to daily Occupational Performance (CO-OP) approach as telehealth for a child with developmental coordination disorder (DCD).

Methods

The intervention method was CO-OP-based tele-occupational therapy for a boy with DCD and his mother; 10 sessions were conducted using a video-conferencing system. This study used the Canadian Occupational Performance Measure (COPM) and the Performance Quality Rating Scale (PQRS) as assessment tools. The PQRS evaluated each occupational performance based on videos recorded during the online sessions and videos taken by the mother of the child.

Results

The CO-OP approach improved COPM performance and satisfaction as well as PQRS scores in the following five goals: (1) handwriting, (2) column addition, (3) jumping rope, (4) playing on the bar, and (5) riding a bicycle.

Conclusions

An online approach based on the CO-OP was realistic and effective, to some extent. Continuing to develop telehealth interventions in the future is recommended.

Cognitive Orientation to Daily Occupational Performance: A Randomized Controlled Trial Examining Intervention Effects on Children with Developmental Coordination Disorder Traits

Children with traits of developmental coordination disorder (DCD-t) may experience occupational performance problems that go unrecognized and therefore may not be adequately supported. The cognitive orientation to daily occupational performance (CO-OP) approach has been effective in interventions for developmental coordination disorder (DCD). Based on an open-label, randomized controlled trial design, this study evaluated the effects of CO-OP on the occupational performance and motor skills of older kindergarten children with DCD-t using the School Assessment of Motor and Process Skills (S-AMPS) and the Movement Assessment Battery for Children, Second Edition. Children with a total DCDQ score of less than 40 or M-ABC2 scores in the 5th to 16th percentile were considered to have DCD-t. Furthermore, children with DCD-t and S-AMPS process skills less than 0.7 were considered to have DAMP (Deficits in Attention, Motor control and Perception)-t. After 3 months of CO-OP intervention, the performance and motor skills of children with DCD-t improved significantly. However, there were no significant changes noted in the motor skills of children with DAMP-t, although their occupational performance improved. These results suggest that CO-OP is effective even for older kindergarten children with DCD-t. However, further improvement of the CO-OP approach or a different strategy is required for children with ADHD comorbidity.

The Cognitive Orientation to daily Occupational Performance (CO-OP) Approach is superior to ordinary treatment for achievement of goals and transfer effects in children with cerebral palsy and spina bifida - a randomized controlled trial

PURPOSE

Children with cerebral palsy (CP) or spina bifida (SB) often have executive dysfunction affecting activity performance. With the Cognitive Orientation to daily Occupational Performance (CO-OP) Approach, children find their own way to perform activities, using problem-solving strategies and meta-cognitive thinking. The present study aimed to investigate the effectiveness of the CO-OP Approach in children with CP or SB, compared with conventional rehabilitation, in achieving self-identified activity goals, and to explore any generalization and transfer effects.

METHOD

Randomized controlled trial, CO-OP versus treatment as usual, 38 children (7-16 years) participated. Each child identified four goals (to study generalization and transfer, one remained untrained). Primary outcomes: Canadian Occupational Performance Measure (COPM) and Performance Quality Rating Scale (PQRS). Secondary outcomes assessed executive functions and self-rated everyday-life competence.

RESULTS

Self-rated goal attainment (COPM) was significantly greater for both trained and untrained goals in the CO-OP group compared with the control group. The rating of observed performance (PQRS) was significantly higher for trained goals in the CO-OP group. The CO-OP group experienced fewer problems in everyday life after treatment. Executive functions did not differ significantly between groups.

CONCLUSION

CO-OP is more effective than ordinary treatment in achieving both trained and untrained goals.IMPLICATIONS FOR REHABILITATIONCO-OP enables children with CP (MACS levels I-III) or SB without intellectual disabilities to reach self-identified goals.CO-OP shows transfer effects to new activities and situations, which may enhance children's self-efficacy.CO-OP is an important complement to conventional rehabilitation services for children with CP and SB.

Cerebellar Differences after Rehabilitation in Children with Developmental Coordination Disorder

Developmental coordination disorder (DCD) affects a child’s ability to learn motor skills. Cognitive Orientation to daily Occupational Performance (CO-OP) is one of the recommended treatments to help achieve functional motor goals. The purpose of this study was to determine if CO-OP intervention induces functional improvements and structural changes in the cerebellum of children with DCD. Using a randomized waitlist-controlled trial, we investigated the effects of CO-OP intervention on cerebellar volume in 47 children with DCD (8–12 years old). Outcome measures included the Canadian Occupational Performance Measure, Performance Quality Rating Scale (PQRS), and Bruininks–Oseretsky Test of Motor Proficiency-2. The SUIT toolbox was used to carry out voxel-based morphometry using T1-weighted MRI scans. Children with DCD showed improved motor outcomes and increased gray matter volume in the brainstem, right crus II, bilateral lobules VIIIb, and left lobule IX following CO-OP. Significant associations were found between PQRS scores and regional gray matter changes in the brainstem, right crus II, right lobule VIIb, right and left lobule VIIIb, and vermis IX. Given the improved motor and brain outcomes with CO-OP, it is recommended that children with DCD be referred for this rehabilitation intervention.

Effectiveness of Cognitive Orientation to Occupational Performance intervention in improving motor skills of children with developmental coordination disorder: A randomized waitlist-control trial

OBJECTIVES

To determine if Cognitive Orientation to Occupational Performance was effective in improving performance and transfer of motor learning in children with developmental coordination disorder (with/without attention deficit hyperactivity disorder); and whether outcomes were maintained three months post-intervention.

DESIGN

Randomized waitlist-control trial (ClinicalTrials.gov ID: NCT02597751).

SETTING

BC Children's Hospital, Vancouver, Canada.

SUBJECTS

Thirty-seven children with developmental coordination disorder and 41 children with co-occurring attention deficit hyperactivity disorder (all 8-12 years), randomized to treatment or waitlist groups.

INTERVENTIONS

One-hour of intervention once weekly for 10 weeks.

MAIN MEASURES

(1) Canadian Occupational Performance Measure to measure self-perceived performance of motor goals (10-point scale); (2) Performance Quality Rating Scale to measure therapist-observed movement quality (10-point scale); and (3) Bruininks-Oseretsky Test of Motor Proficiency - 2nd ed. to measure overall motor skill ability/transfer of motor learning (percentile).

RESULTS

Both groups showed significant improvement (p < 0.001) in motor performance (developmental coordination disorder: pre: 2.7 ± 2.2, post: 7.0 ± 1.0; developmental coordination disorder with attention deficit hyperactivity disorder: pre: 2.3 ± 1.7, post: 7.0 ± 1.5) and movement quality (developmental coordination disorder: pre: 3.0 ± 1.5, post: 6.3 ± 1.7; developmental coordination disorder with attention deficit hyperactivity disorder: pre: 3.0 ± 1.9, post: 5.7 ± 2.3). Three months after treatment, children maintained their gains, but only children with developmental coordination disorder showed transfer of learning to overall motor skills (pre:12 ± 15, post:12 ± 12, follow-up:14 ± 20, p < 0.001).

CONCLUSION

Intervention was similarly effective for children with developmental coordination disorder with/without attention deficit hyperactivity disorder in achieving and maintaining functional motor goals, but only children with developmental coordination disorder showed transfer of learning to other motor skills.

Benefits of an Intensive Individual CO-OP Intervention in a Group Setting for Children with DCD

Purpose

The present study focused on the impact of an adapted Cognitive Orientation to daily Occupational Performance (CO-OP) five-day intervention program for children with developmental coordination disorder (DCD). Important adaptations were the new combination of individual CO-OP sessions and group activities, the short and intensive program that was followed by a training and coaching trajectory, and the use of video logs.

Materials and Methods

Eighteen children with DCD (aged 8-16 years) participated in the five-day intervention during which they worked on three intervention goals. After the intervention, during an eight-week training and coaching trajectory for parents and children, children worked on a transfer goal. Assessment took place at four moments in time: two pretest measures, a posttest measure, and a 3-month follow-up measure. Primary outcome measures focused on changes in performance and satisfaction of self-chosen intervention and transfer goals. The secondary outcome measure explored changes in children's attitude, motivation, and confidence in relation to motor skill activities, social skills, and level of participation.

Results

Significant improvements were found with regard to the performance and satisfaction of intervention goals. For the transfer goal, only parents reported significant improvements. Finally, parents indicated potential improvements with regard to the attitude, motivation, and confidence of their children, but not for their social skills or level of participation.

Conclusion

The findings are promising with regard to the efficacy of this adapted CO-OP intervention for improving intervention goals, but less effective for transfer of learned skills to other goals after the intervention. Future research should focus on how postintervention parental coaching can be improved in order to increase generalization and transfer.

Cognitive Orientation to Daily Occupational Performance (CO-OP) in Children with Cerebral Palsy: A Systematic Review with Meta-analysis

Background: Cognitive orientation to daily occupational performance (CO-OP) is a client-centered treatment approach that was developed in the 1990s by occupational therapists. Purpose: Exploring current evidence about the effectiveness of CO-OP on children with cerebral palsy (CP). Method: Major electronic databases were searched. A narrative synthesis of current literature and meta-analyses on randomized control trials (RCTs) were conducted on changes in occupational performance. Findings: Seven studies with 103 participants were included. Four studies were RCTs with moderate levels of evidence, and three studies had single-subject designs. Although beneficial effects of CO-OP on goal achievement and transferring learned skills were reported, meta-analyses showed that CO-OP had no significant effect on the performance (WMD = 1.52, 95% CI = -1.58 to 4.63, P = .33) and satisfaction domains (WMD = 1.71, 95% CI = -1.14 to 4.57, P = .24) of Canadian Occupational Performance Measure scores compared to alternative interventions. Implications: CO-OP improves occupational performance but not more than alternative interventions. Results are inconclusive due to small sample sizes and heterogeneity of alternative interventions and participants. Therefore, research with a larger number of participants with sound RCT methods is needed.

A Performance-Based Teleintervention for Adults in the Chronic Stage after Acquired Brain Injury: An Exploratory Pilot Randomized Controlled Crossover Study

This pilot study aimed to investigate the initial effect of a remotely delivered performance-based client-centered intervention on activity performance and participation among adults in the chronic phase after acquired brain injury (ABI). Sixteen participants living at home with little to no assistance in basic daily activities were allocated into intervention or waitlist control groups. Assessments were conducted at the baseline, after the 3-month intervention/wait period, and at a 3-month follow-up. The primary outcomes were activity performance using the Canadian Occupational Performance Measure (COPM) and the Performance Quality Rating Scale (PQRS) and participation using the Mayo-Portland Adaptability Inventory-4 (MPAI-4). The intervention included weekly videoconferencing sessions using the Cognitive Orientation to Daily Occupational Performance approach (tele-CO-OP). The participants identified five functional goals, of which three were directly addressed. Wilcoxon signed-ranks test results showed no significant improvements in the control group at the end of the 3-month wait period. Pooled data from both groups showed significant improvements in COPM scores for trained and untrained goals following the intervention. Significant improvements were also found in the PQRS and MPAI-4 scores. Improvements were partially maintained at follow-up. Our preliminary results suggest that tele-CO-OP may positively impact the lives of adults after ABI who are coping with long-term disability.

Brain functional connectivity in children with developmental coordination disorder following rehabilitation intervention

BACKGROUND

Children with developmental coordination disorder (DCD) show improved motor function after Cognitive Orientation to Occupational Performance (CO-OP) intervention; however, the neural basis for these improvements is unknown.

METHODS

In this randomized waitlist-controlled trial, 78 children with DCD (with/without ADHD) were randomly assigned to either a treatment or waitlist group and underwent three resting-state MRI scans over six months. The treatment group received intervention between the first and second scan; the waitlist group received intervention between the second and third scan.

RESULTS

After CO-OP intervention, children with DCD [13 male, 8 female; mean (SD) age: 10.0 (1.7) years] showed increased functional connectivity between the default mode network and right anterior cingulate gyrus (p < 0.01). Additional gains were noted at follow-up three months after the intervention, with greater functional connectivity between the dorsal attention network and precentral gyrus (p < 0.02). However, children with DCD + ADHD [18 male, 1 female; mean (SD) age: 10.0 (1.14) years] did not show brain changes following CO-OP.

CONCLUSION

For children with DCD, increased functional connectivity in networks associated with self-, emotion-, and attention-regulation may underlie motor skill improvements observed after CO-OP intervention. Modifications to the CO-OP protocol may be required to induce similar brain changes in children with DCD + ADHD.

IMPACT

This study provides neuroscientific evidence for the Cognitive Orientation to Occupational Performance (CO-OP) approach as an effective rehabilitation intervention to induce brain and behavioral changes in children with DCD. While children with DCD ± ADHD showed improved motor function after CO-OP, only children with DCD showed brain changes after intervention. Children with DCD showed increased functional connectivity in networks associated with self-, emotion-, and attention-regulation after the intervention. Treatment modifications may be required to induce similar brain changes in children with DCD + ADHD. Pediatricians are encouraged to refer children with DCD  with and without ADHD for CO-OP intervention to improve their motor skills.

White Matter Changes With Rehabilitation in Children With Developmental Coordination Disorder: A Randomized Controlled Trial

Background and Objectives: Children with developmental coordination disorder (DCD) have difficulty learning motor skills, which can affect their participation in activities of daily living and psychosocial well-being. Over 50% of children with DCD also have attention deficit hyperactivity disorder (ADHD), which further exacerbates their motor problems and impact on quality of life. A rehabilitation approach known as Cognitive Orientation to Occupational Performance uses problem-solving strategies to help children learn motor skills they wish to achieve. While this cognitive approach has been effective for children with DCD, few studies have examined the effectiveness of this approach for children with co-occurring ADHD. Further, the underlying mechanism and neural basis of this intervention are largely unknown.

Methods: In this randomized waitlist-controlled trial, we used MRI to examine white matter microstructure after intervention in 8–12-year-old children with DCD (n = 28) and with DCD and co-occurring ADHD (n = 25). Children in both groups were randomized to either a treatment group or waitlist group at their first MRI. The treatment group began the intervention after their MRI scan and returned for a post-treatment scan at 3 months, and follow-up scan at 6 months; the waitlist group waited 3 months before their second MRI, received the intervention, and then had a post-treatment scan. Each child received intervention once weekly for 10 weeks. Diffusion tensor imaging was used to acquire white matter diffusion parameters and was analyzed using tract-based spatial statistics (TBSS).

Results and Conclusion: Children with DCD showed significant improvement in white matter microstructure in the bilateral anterior thalamic radiation, bilateral sensorimotor tract, bilateral cingulum, fornix, splenium and body of corpus callosum, right inferior fronto-occipital fasciculus, and white matter pathways to bilateral inferior gyri, right middle frontal gyrus, frontal medial cortex, and left cuneus. We suggest that these rehabilitation-induced neural changes in children with DCD occurred in regions associated with attention, self-regulation, motor planning, and inter-hemispheric communication, which positively affected brain connectivity and motor function. In contrast, children with DCD and co-occurring ADHD did not show any brain changes following the intervention. Modifications to the treatment protocol might help address the attentional and self-regulatory needs of children with a dual diagnosis.

The switch access measure: development and evaluation of the reliability and clinical utility of a switching assessment for children with severe and multiple disabilities

PURPOSE

Children with severe, multiple disabilities often need to use switches to control their assistive technology. We developed the Switch Access Measure (SAM) to address the lack of validated functional activity-based measures to evaluate children's success using their prescribed switch(es). This goal-based performance measure evaluates switching ability on 16 skills items (6 motor, 2 visual, and 8 process). This study investigated SAM's reliability and confidence in scoring.

METHODS

Two occupational therapists with switch access intervention experience were trained as SAM study assessors. They independently scored SAM (inter-rater reliability) while viewing 20 study assessment videos where each child undertook at least one goal-based switching activity with their technology, and rated confidence in scoring for each SAM item. The SAM's two developers independently scored these videos as an inter-rater reliability benchmark. Each study assessor re-scored a subset of 10 videos 2-3 weeks later (intra-rater reliability).

RESULTS

SAM Total score inter-rater reliability was excellent for the two study assessors (ICC =0.82) and the two SAM developers (ICC = 0.95). Inter-rater reliability was lowest (moderate) for Motor Subsection for the assessors, but still excellent for the developers. Intra-reliability for both groups of raters was excellent for Total and Subsection scores. Assessors' confidence in scoring was high (mean of 84.7% and 86.8% respectively) across items/participants.

CONCLUSIONS

SAM is sufficiently reliable for clinical use, permitting clinicians, after SAM training and certification, to include it in their assessments and in development of switch access intervention plans for children with severe, multiple disabilities.IMPLICATIONS FOR REHABILITATIONFor practitioners new to the field of switching technology, the SAM will provide a comprehensive understanding of all the components of successful switch use that need consideration when working with those needing switch access technologies.For all practitioners in this area, the SAM offers a consistent language to support clear communication among professionals, families, clients and their support networks. The SAM also gives quantifiable and reliable data to back clinical decision making, particularly important to support the case for funding of these technologies.Use of the SAM will prompt discussions with clients, families and carers and lead to better understanding of strengths and challenges, thus enhancing collaborative working relationships in the pursuit of achieving the best possible outcomes for those needing to use switch access technologies.

Efficacy of the Cognitive Orientation to daily Occupational Performance (CO-OP) approach with and without parental coaching on activity and participation for children with developmental coordination disorder: A randomized clinical trial

BACKGROUND

Cognitive Orientation to daily Occupational Performance (CO-OP) is recommended for its effectiveness in improving activity performance in children with Developmental Coordination Disorder (DCD). Since parental support is a key element in CO-OP, parental coaching seems relevant to be investigated.

AIMS

Compare the efficacy of the CO-OP Approach with and without additional parental coaching to improve activity and participation in children with DCD.

METHODS AND PROCEDURES

Randomized clinical trial with 7-12-years-old children with DCD, randomly assigned to experimental (E-group) or active control (AC-group) groups, with 11 children each. Both groups received traditional CO-OP, E-group received four additional parental group-coaching sessions. Occupational performance and satisfaction on intervention goals were measured at baseline, post-intervention, and follow-up. Participation, motor performance and executive function were assessed at baseline and post-intervention.

OUTCOMES AND RESULTS

CO-OP with and without additional parental coaching resulted in improved occupational performance according to children, parents, and external evaluators. Children showed statistically significant gains in motor performance and cognitive flexibility. Participation measures did not change.

CONCLUSIONS AND IMPLICATIONS

As coaching did not add additional gains, parent's required participation in CO-OP might be enough to support children's occupational performance.

The Relative Merits of an Individualized Versus a Generic Approach to Rating Functional Performance in Childhood Dystonia

Aims. The Performance Quality Rating Scale (PQRS) is an observational measure that captures performance at the level of activity and participation. Developed for use with the Cognitive Orientation to daily Occupational Performance (CO-OP), it is a highly individualized approach to measurement. CO-OP is currently being studied in childhood-onset hyperkinetic movement disorders (HMD) and deep brain stimulation. The purpose of this study was to compare two different approaches to rating performance, generic (PQRS-G) and individualized (PQRS-I), for children with childhood-onset hyperkinetic movement disorders (HMD) including dystonia. Method. Videotaped activity performances, pre and post intervention were independently scored by two blind raters using PQRS-G PQRS-I. Results were examined to determine if the measures identified differences in e performance on goals chosen by the participants and on change scores after intervention. Dependent t-tests were used to compare performance and change scores. Results. The two approaches to rating both have moderate correlations (all data: 0.764; baseline: 0.677; post-intervention: 0.725) and yielded some different results in capturing performance. There was a significant difference in scores at pre-intervention between the two approaches to rating, even though post-intervention score mean difference was not significantly different. The PQRS-I had a wider score range, capturing wider performance differences, and greater change between baseline and post-intervention performances for children and young people with dystonic movement. Conclusions. Best practice in rehabilitation requires the use of outcome measures that optimally captures performance and performance change for children and young people with dystonic movement. When working with clients with severe motor-performance deficits, PQRS-I appears to be the better approach to capturing performance and performance changes.

Physical Literacy as A Framework of Assessment and Intervention for Children and Youth with Developmental Coordination Disorder: A Narrative Critical Review of Conventional Practice and Proposal for Future Directions

A framework of literacy may have roles to play in the assessment and treatment of children and youth with developmental disorders. This review aims to evaluate the conventional practice of assessment and treatment for children and youth with a developmental disorder in the physical domain, called developmental coordination disorder (DCD), and explore how the framework of physical literacy could contribute to the advancement of the current practice. This study adopts a method of narrative critical review based on a non-systematic search for its broad coverage to provide insights into the trend and future alternative directions. Over recent decades, children and youth with DCD have been typically assessed with standardized norm-referenced tests, before and after task-oriented intervention, for aiding diagnosis and evaluating the treatment effect. However, a recent high-quality systematic review showed limited evidence for the treatment effect assessed by the tests. Here, a framework of physical literacy is proposed to be used as an alternative to the conventional practice by recalibrating treatment goals and modifying the assessment and intervention approaches; criterion-referenced real-life authentic assessment and activities are encouraged with an emphasis on the enjoyment of movement and value of physical activity towards the attainment of physically active and healthy lifestyle goals from a lifespan perspective. The application of the physical literacy framework to the assessment and treatment of DCD needs to be further examined conceptually and empirically, while exploring a potential contribution of the literacy framework to transform the conventional assessment and treatment of children and youth with other developmental disorders.

Protocol: Using Single-Case Experimental Design to Evaluate Whole-Body Dynamic Seating on Activity, Participation, and Quality of Life in Dystonic Cerebral Palsy

Introduction: People with hyperkinetic movement disorders, including dystonia, experience often painful, involuntary movements affecting functioning. Seating comfort is a key unmet need identified by families. This paper reports a protocol to assess the feasibility and preliminary evidence for the efficacy of dynamic seating to improve functional outcomes for young children with dystonic cerebral palsy (DCP). Design: A series of single-case experimental design N-of-1 trials, with replications across participants, with a random baseline interval, and one treatment period (n = 6). Methods: Inclusion criteria: DCP; 21.5 cm < popliteal fossa to posterior sacrum < 35 cm; Gross Motor Function Classification System level IV-V; mini-Manual Ability Classification System level IV-V; difficulties with seating. Intervention: Trial of the seat (8 weeks), with multiple baseline before, during and after intervention and 2 month follow up. The baseline duration will be randomised per child (2-7 weeks). Primary outcomes: Performance Quality Rating Scale; Canadian Occupational Performance Measure; seating tolerance. The statistician will create the randomization, with allocation concealment by registration of participants prior to sending the allocation arm to the principal investigator. Primary outcomes will be assessed from video by an assessor blind to allocation. Analysis: Participant outcome data will be plotted over time, with parametric and non-parametric analysis including estimated size effect for N-of-1 trials.

Combining Virtual Reality Motor Rehabilitation With Cognitive Strategy Use in Chronic Stroke

Importance: Rehabilitation interventions for chronic stroke are largely impairment based, with results confined to the level of impairment instead of function. In contrast, cognitive strategy training interventions have demonstrated clinically meaningful improvements in functional outcomes. Integration of these approaches has yet to be explored.

Objective: To evaluate acceptability, recruitment, and retention rate and determine which outcome measures best capture the effect of the intervention.

Design: Single-group, pre–post design.

Setting: Research laboratory.

Participants: Adults with chronic stroke and hemiparesis (N = 10).

Intervention: A 12-wk intervention integrating cognitive strategy training with upper extremity motor training. Two weekly sessions used Kinect-based virtual reality to encourage high numbers of upper extremity movement repetitions. The third weekly session focused on the use of cognitive strategies with practice of client-centered goals.

Outcomes and Measures: Upper extremity motor performance was measured with the Fugl–Meyer Assessment. Occupational performance on trained and untrained goals was measured via the Performance Quality Rating Scale and the Canadian Occupational Performance Measure. Outcome data were gathered preintervention, postintervention, and at 3-mo follow-up.

Results: The intervention was perceived as acceptable. Recruitment rate was 15%, and retention rate was 100%. Large effects were found on outcomes of upper extremity motor performance, occupational performance, and participation at follow-up.

Conclusion and Relevance: MetacogVR is feasible for adults with chronic stroke. The effect of MetacogVR is best captured through measures of upper extremity motor performance, occupational performance, and participation.

What This Articles Adds: Traditional, impairment-based approaches to chronic stroke rehabilitation may require integration with cognitive-strategy training to affect performance on meaningful goals.

Cognitive oriented strategy training augmented rehabilitation (COSTAR) for ischemic stroke: a pilot exploratory randomized controlled study

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.

Effectiveness of occupation-based interventions on performance's quality for hemiparetic stroke in community-dwelling: A randomized clinical trial study

BACKGROUND

Occupations define activities that people perform to occupy themselves and that people have meaning and value to them. The use of occupation-based intervention addresses activity daily of living performance.

OBJECTIVES

This study was to investigate the effects of occupation-based interventions on performance's quality for hemiparetic stroke in community-dwelling.

METHODS

Forty-three participants were enrolled in this study with a full understanding of the purpose and method of the research and had a diagnosis with hemiparetic stroke. Participants were randomized to one of two treatment groups: Experimental group (n = 23) or control groups (n = 20). The experimental group applied occupation-based intervention and control group applied action focusing intervention. All participants underwent ten treatment sessions during the study period and conducted pre- and post-assessment. Several instruments were used to measure quality of performance.

RESULTS

After the intervention training, the qualities of occupational performance were significantly higher in the experimental group applied occupation-based intervention than the control group applied action focusing intervention (p < 0.001).

CONCLUSIONS

Based on the results of this study, occupation-based intervention has positive effects on quality of performing daily activities and occupational activities independently in persons with hemiparetic stroke.

Effects of an Exergame Software for Older Adults on Fitness, Activities of Daily Living Performance, and Quality of Life

BACKGROUND

As people become older, the biological process of aging leads to a decline in functional capabilities, which entails difficulties in the performance of daily tasks. Within the "Active and Assisted Living Joint Programme" a consortium from Spain, Germany, and Switzerland developed an interactive Exergame software for older adults to maintain their physical abilities and independence within the daily tasks.

SUBJECTS AND METHODS

An interventional study was conducted to validate the software. For 3 months, Swiss and Spanish seniors used the system at least three times a week for minimum half an hour in their homes. The physical condition in terms of maintaining or increasing strength, balance, safety, and mobility of the seniors was assessed by using the Berg Balance Scale and the Senior Fitness Test. In addition, the effect on independence within the activities of daily living was assessed by using the Canadian Occupational Performance Measure, the Performance Quality Rating Scale, and the Iconographical Falls Efficacy Scale. We used the EQ 5D to evaluate the "quality of life."

RESULTS

Twenty-nine participants (male; n = 14; female; n = 15) completed the study. Scores of endurance (2 minutes step test; P = 0.01, η² = 0.3) increased significantly. Moderate effect sizes in quality of life (r = 0.3), lower body strength (η² = 0.08), and large effect sizes in endurance (η² = 0.3) were detected. A small effect was evaluated within the gait speed (r = 0.2), mobility in the lower body (r = 0.2), and the balance capabilities (r = 0.2).

CONCLUSION

The results of this study lead us to the conclusion that physical training with activity-focused exergames that are related to the everyday tasks of older adults could help to maintain and improve the individual fitness status.

LSVT BIG in late stroke rehabilitation: A single-case experimental design study

BACKGROUND.

Late stroke rehabilitation interventions often target impairment with limited carryover to daily occupation.

PURPOSE.

This study explored whether the LSVT BIG program could lead to improved performance in client-identified occupations and decreased impairment late poststroke.

METHOD.

A single-case experimental design with one repetition was completed. Participants were two adults who had experienced a stroke 3 and 12 years previously. Each participant selected up to six occupational goals, and the intervention was applied to half. Repeated measures were taken using the Canadian Occupational Performance Measure and the Rating of Everyday Arm-Use in the Community and Home. Additional measures of performance and impairment were applied pre- and postintervention.

FINDINGS.

Performance improved on either self-assessment or blinded-rater assessment for all but one activity (trained or untrained).

IMPLICATIONS.

LSVT BIG is a promising intervention to improve occupational performance. Further research is required to clarify elements of the program essential to improving occupational performance.

International clinical practice recommendations on the definition, diagnosis, assessment, intervention, and psychosocial aspects of developmental coordination disorder

AIM

These international clinical practice recommendations (CPR) for developmental coordination disorder (DCD), initiated by the European Academy of Childhood Disability (EACD), aim to address key questions on the definition, diagnosis, assessment, intervention, and psychosocial aspects of DCD relevant for clinical practice.

METHOD

Key questions in five areas were considered through literature reviews and formal expert consensus. For recommendations based on evidence, literature searches on 'mechanisms', 'assessment', and 'intervention' were updated since the last recommendations in 2012. New searches were conducted for 'psychosocial issues' and 'adolescents/adults'. Evidence was rated according to the Oxford Centre for Evidence-Based Medicine (level of evidence [LOE] 1-4) and transferred into recommendations. For recommendations based on formal consensus, two meetings of an international, multidisciplinary expert panel were conducted with a further five Delphi rounds to develop good clinical practice (GCP) recommendations.

RESULTS

Thirty-five recommendations were made. Eight were based on the evidence from literature reviews (three on 'assessment', five on 'intervention'). Twenty-two were updated from the 2012 recommendations. New recommendations relate to diagnosis and assessment (two GCPs) and psychosocial issues (three GCPs). Additionally, one new recommendation (LOE) reflects active video games as adjuncts to more traditional activity-oriented and participation-oriented interventions, and two new recommendations (one GCP, one LOE) were made for adolescents and adults with DCD.

INTERPRETATION

The CPR-DCD is a comprehensive overview of DCD and current understanding based on research evidence and expert consensus. It reflects the state of the art for clinicians and scientists of varied disciplines. The international CPR-DCD may serve as a basis for national guidelines.

WHAT THIS PAPER ADDS

Updated international clinical practice guidelines on developmental coordination disorder (DCD). Refined and extended recommendations on clinical assessment and intervention for DCD. A critical synopsis of current research on mechanisms of DCD. A critical synopsis of psychosocial issues in DCD, with implications for clinical practice. The first international recommendations to consider adolescents and adults with DCD.

Protocol for N-of-1 trials with replications across therapists for childhood-onset dystonia rehabilitation: Study 2: Protocole des essais à effectif unique avec répétitions par différents ergothérapeutes pour la réadaptation de la dystonie débutant dans l'enfance : Étude 2

BACKGROUND

Currently, no evidence-based rehabilitation interventions are available for hyperkinetic movement disorders (HMD), including dyskinetic cerebral palsy (CP). Among these highly heterogeneous disorders, dystonia is the predominant disorder. The Cognitive Orientation to daily Occupational Performance (CO-OP) Approach-a task-oriented, performance-based intervention to enable participation-is currently being evaluated for its potential as an intervention option.

PURPOSE

This paper reports the protocol for the second of two studies designed to evaluate the potential of CO-OP to improve functional outcomes for individuals with HMD following deep brain stimulation (DBS). This second study is a systematic replication across multiple treating therapists from multiple centres.

METHOD

Systematic replications will be used across centres and treating therapists trained in the CO-OP, using a series of randomized multiple-baseline N-of-1 trials. Participants will be ages 6 to 21 years with HMD and DBS as indicated by the Manual Ability Classification System. Data collection will involve multiple data points collected at baseline, during intervention, and after intervention. The intervention will involve occupation-based goal setting followed by 10 individualized CO-OP sessions. The primary outcome measures are the Performance Quality Rating Scale and the Canadian Occupational Performance Measure. Outcome data will be plotted over time for each participant and supplemented with graph statistical analysis and estimate size effect for N-of-1 trials.

IMPLICATIONS

The results of this study will help to inform future training procedures and future clinical trials.

Protocol for N-of-1 trials proof of concept for rehabilitation of childhood-onset dystonia: Study 1: Protocole des essais de validation à effectif unique pour la réadaptation de la dystonie débutant dans l'enfance : Étude 1

BACKGROUND

Hyperkinetic movement disorders (HMD) are a heterogeneous group of neurological conditions among which dystonia is the predominant disorder and dyskinetic cerebral palsy the largest secondary dystonia group. Currently, there are no evidence-based, non-medical management options for childhood HMD. The Cognitive Orientation to daily Occupational Performance (CO-OP) Approach is a task-oriented, performance-based intervention that focuses on participation.

PURPOSE

This paper reports the protocol for a proof-of-concept study to assess feasibility and preliminary evidence regarding efficacy of CO-OP for HMD following deep brain stimulation (DBS).

METHOD

A series of N-of-1 trials with replications will be conducted with children, ages 6 and 21 years with HMD and DBS as indicated by the Manual Ability Classification System. Ten individualized CO-OP sessions, with multiple baselines before, during, and after, will be completed. The primary outcome measures are the Performance Quality Rating Scale and the Assessment of Motor and Process Skills. Outcome data will be plotted over time for each participant and supplemented with graph statistical analysis and effect size estimates.

IMPLICATIONS

A written protocol will be developed based on evidence and feedback incorporating any changes to the CO-OP intervention for children and young people with HMD, as per the Medical Research Council's Framework for Complex Interventions.

Potential benefits of the cognitive orientation to daily occupational performance approach in young adults with spina bifida or cerebral palsy: a feasibility study

Purpose: People with cerebral palsy (CP) or spina bifida (SB) often struggle to perform everyday-life activities. Both groups frequently also have difficulties in creating and using strategies effectively when performing tasks. The cognitive orientation to daily occupational performance (CO-OP) Approach combines the learning of cognitive strategies with task-specific approaches through a client-centred procedure. The aim of this study was to investigate whether the CO-OP Approach is feasible for and potentially beneficial to adolescents and young adults with CP or SB in Sweden by analysing four areas of feasibility (acceptability, efficacy, adaptation, and expansion).Methods: Exploratory multiple-case study using mixed methods. Ten persons aged 16-28, five with each condition, participated in an intervention period. Assessments were performed on three occasions: baseline, post-intervention, and six-month follow-up.Results: The result demonstrates that the CO-OP Approach has the potential to enable adolescents and young adults with either condition to achieve personal goals and to enhance their planning skills and their ability to use strategies when performing activities. This approach is also compatible with the core values of habilitation in Sweden and was found by the participants to be highly meaningful and useful.Conclusions: The CO-OP Approach is feasible for adolescents and young adults with SB or CP in Sweden.Implications for rehabilitationThe Cognitive Orientation to daily Occupational Performance• is a feasible approach for adolescents and young adults with spina bifida and with cerebral palsy.• is a promising approach when it comes to enabling the achievement of personal goals.• might have potential to enhance executive functioning through strategy use.• is in line with the fundamental core values of disability rights of inclusion, empowerment, and participation.

The Canadian occupational performance measure for patients with stroke: a systematic review

[Purpose] This study investigated whether the Canadian Occupational Performance Measure is a suitable outcome measure for assessing patients with stroke in research and clinical settings. [Subjects and Methods] The study included into two parts: (1) an investigation of the reliability and validity of the Canadian Occupational Performance Measure for patients with stroke and (2) an exploration of Canadian Occupational Performance Measure results in randomized controlled trials of patients with stroke. For this review, the study searched the MEDLINE, PubMed, and CINAHL Plus with Full Text databases for articles published before September 2015. [Results] Finally, three eligible articles were collected in part 1, and ten randomized controlled trials studies were collected in part 2. The findings of part 1 revealed that the Canadian Occupational Performance Measure had efficient test-retest reliability, however, the Canadian Occupational Performance Measure revealed weak associations with other assessment tools such as Barthel Index used for patients with stroke. Six of the randomized controlled trials studies used the Canadian Occupational Performance Measure as a primary outcome and two as a secondary outcome, while the other two as a goal-setting instrument. [Conclusion] This review indicates that the Canadian Occupational Performance Measure is appropriate for clinicians, including physiotherapists, in assessing outcome for patients with stroke. The Canadian Occupational Performance Measure can assist patients in identifying their outcome performance and provide therapists with directions on interventions.

The International Classification of Functioning (ICF) to evaluate deep brain stimulation neuromodulation in childhood dystonia-hyperkinesia informs future clinical & research priorities in a multidisciplinary model of care

The multidisciplinary team (MDT) approach illustrates how motor classification systems, assessments and outcome measures currently available have been applied to a national cohort of children and young people with dystonia and other hyperkinetic movement disorders (HMD) particularly with a focus on dyskinetic cerebral palsy (CP). The paper is divided in 3 sections. Firstly, we describe the service model adopted by the Complex Motor Disorders Service (CMDS) at Evelina London Children's Hospital and King's College Hospital (ELCH-KCH) for deep brain stimulation. We describe lessons learnt from available dystonia studies and discuss/propose ways to measure DBS and other dystonia-related intervention outcomes. We aim to report on current available functional outcome measures as well as some impairment-based assessments that can encourage and generate discussion among movement disorders specialists of different backgrounds regarding choice of the most important areas to be measured after DBS and other interventions for dystonia management. Finally, some recommendations for multi-centre collaboration in regards to functional clinical outcomes and research methodologies for dystonia-related interventions are proposed.

Combined Cognitive-Strategy and Task-Specific Training Affects Cognition and Upper-Extremity Function in Subacute Stroke: An Exploratory Randomized Controlled Trial

The purpose of this study was to estimate the effect of Cognitive Orientation to Daily Occupational Performance (CO-OP) compared with usual occupational therapy on upper-extremity movement, cognitive flexibility, and stroke impact in people less than 3 mo after stroke. An exploratory, single-blind randomized controlled trial was conducted with people referred to outpatient occupational therapy services at two rehabilitation centers. Arm movement was measured with the Action Research Arm Test, cognitive flexibility with the Delis-Kaplan Executive Function System Trail Making subtest, and stroke impact with subscales of the Stroke Impact Scale. A total of 35 participants were randomized, and 26 completed the intervention. CO-OP demonstrated measurable effects over usual care on all measures. These data provide early support for the use of CO-OP to improve performance and remediate cognitive and arm movement impairments after stroke over usual care; however, future study is warranted to confirm the effects observed in this trial.

Combined Cognitive-Strategy and Task-Specific Training Improve Transfer to Untrained Activities in Subacute Stroke: An Exploratory Randomized Controlled Trial

PURPOSE

The purpose of this study was to estimate the effect of the Cognitive Orientation to daily Occupational Performance (CO-OP) approach compared with usual outpatient rehabilitation on activity and participation in people <3 months poststroke.

METHODS

An exploratory, single-blind, randomized controlled trial, with a usual-care control arm, was conducted. Participants referred to 2 stroke rehabilitation outpatient programs were randomized to receive either usual care or CO-OP. The primary outcome was actual performance of trained and untrained self-selected activities, measured using the Performance Quality Rating Scale (PQRS). Additional outcomes included the Canadian Occupational Performance Measure (COPM), the Stroke Impact Scale Participation Domain, the Community Participation Index, and the Self-Efficacy Gauge.

RESULTS

A total of 35 eligible participants were randomized; 26 completed the intervention. Post intervention, PQRS change scores demonstrated that CO-OP had a medium effect over usual care on trained self-selected activities (d = 0.5) and a large effect on untrained activities (d = 1.2). At a 3-month follow-up, PQRS change scores indicated a large effect of CO-OP on both trained (d = 1.6) and untrained activities (d = 1.1). CO-OP had a small effect on COPM and a medium effect on the Community Participation Index perceived control and on the Self-Efficacy Gauge.

CONCLUSION

CO-OP was associated with a large treatment effect on follow-up performances of self-selected activities and demonstrated transfer to untrained activities. A larger trial is warranted.
