Occupational therapists' descriptions of their work with persons suffering from cognitive impairment following acquired brain injury

Is Virtual Reality Orientation Therapy Useful to Optimize Cognitive and Behavioral Functioning Following Severe Acquired Brain Injury? An Exploratory Study

INTRODUCTION

Severe acquired brain injury (SABI) is a leading cause of death and disability, and it is defined as a brain injury that occurs after birth due to traumatic or non-traumatic causes. Reality orientation therapy (ROT) uses repeated time-place-person orientation and meaningful stimuli to develop a better understanding of the environment and has great potential as an effective strategy to improve cognitive and behavioral functioning.

OBJECTIVE

This study aims to investigate the feasibility and potential effects of virtual reality orientation therapy (VR-rot) on optimizing cognitive and behavioral functioning and depressive symptoms post-SABI.

METHOD

Forty patients with SABI were enrolled from October 2022 to December 2023 and divided into two groups: the experimental group (EG, n = 20) received VR_rot, while the control group (CG, n = 20) received standard ROT (S_rot). All patients were evaluated with a psychometric battery, including the Mini-Mental State Examination (MMSE) and the Hamilton Rating Scale for Depression (HRS-D), administered before (T0) and after the end (T1) of rehabilitation.

RESULTS

Within-group comparisons indicated a statistically significant change in MMSE scores from T0 to T1 in the EG and CG, with the EG showing a greater improvement than the CG. Regarding HRS-D scores, the EG showed a statistically significant change. VR-ROT could be a valuable tool for improving cognitive-behavioral functioning in SABI patients.

CONCLUSIONS

The VRRS can help reduce depressive symptoms and improve the reality orientation deficit caused by traumatic brain injury and stroke on brain tissue. This study highlights the benefits of virtual reality.

Occupational therapists' assessment and reporting of functional cognition in stroke care

PURPOSE

To investigate how functional cognition of people post-stroke is evaluated and reported by occupational therapists in Ireland. Functional cognition refers to the use and integration of cognitive skills for daily function.

METHODS

This study used a qualitative design. Six focus groups and one individual interview were conducted with 20 occupational therapists purposively sampled for variation across different clinical grades. Data were analysed according to the Braun and Clark thematic analysis framework.

RESULTS

Participants felt that assessment of functional cognition was an integral feature of occupational therapy assessment in stroke care but acknowledged that terminology used by occupational therapists for functional cognition was inconsistent. Non-standardised observational assessment was routinely used by participants. Challenges were reported with respect to written documentation of non-standardised observations. Participants reported that use of standardised cognitive assessments required considered clinical reasoning before administration. Standardised performance-based assessments were not widely implemented by participants.

CONCLUSION

Occupational therapists in Ireland reported a multi-component assessment process to evaluate functional cognition post-stroke. Establishing practice guidelines for the assessment of functional cognition may be of benefit to occupational therapists working in stroke care. Further research is needed to quantify procedures in this assessment process to account for variation in practice.

Virtual reality-based music attention training for acquired brain injury: A protocol for randomized cross-over trial

Attention training is the primary step in the rehabilitation for patients with acquired brain injury (ABI). While active music performance has been reported to aid neural and functional recovery, its efficacy for patients with ABI remains uncertain due to methodological concerns. The purpose of the study is to develop a virtual reality-based music attention training (VR-MAT), which utilizes a visually guided, bilateral drumming in an immersive environment to train attention and executive functions. We also aims to examine the feasibility and effectiveness of the VR-MAT with a small sample size of participants (3-60 months after ABI, N = 20 approximately). Participants will be randomly assigned to either a waitlist control or music group, in which VR-MAT will take place five times weekly over 4 weeks (randomized crossover design). The evaluation of VR-MAT performance will include accuracy and response time in music responses. Neurocognitive outcome measures will be administered to quantify pre-post changes in attention, working memory, and executive functions. Additionally, functional near-infrared spectroscopy will be employed to explore the relationships between musical behavior, neurocognitive function, and neurophysiological responses.

Criterion-Related Validation of a Music-Based Attention Assessment for Individuals with Traumatic Brain Injury

The music-based attention assessment (MAA) is a melody contour identification task that evaluates different types of attention. Previous studies have examined the psychometric and physiological validity of the MAA across various age groups in clinical and typical populations. The purpose of this study was to confirm the MAA's criterion validity in individuals with traumatic brain injury (TBI) and to correlate this with standardized neuropsychological measurements. The MAA and various neurocognitive tests (i.e., the Wechsler adult intelligence scale DST, Delis-Kaplan executive functioning scale color-word interference test, and Conner's continuous performance test) were administered to 38 patients within two weeks prior to or post to the MAA administration. Significant correlations between MAA and neurocognitive batteries were found, indicating the potential of MAA as a valid measure of different types of attention deficits. An additional multiple regression analysis revealed that MAA was a significant factor in predicting attention ability.

Analysis of the occupational therapist's professional identity when working in acquired brain injury rehabilitation within a municipal service

Background

Changes in rehabilitation pathways are reducing the amount of time patients spend in hospital, resulting in an earlier return to municipal care. Studies show that occupational therapists find working with patients with acquired brain injury to be complex and that, in some situations, they fail to believe in their own professional expertise. This qualitative study aimed to explore how the professional expertise of occupational therapists working in acquired brain injury rehabilitation within a municipal service is understood.

Methods

One monoprofessional focus group interview with occupational therapists and five focus group interviews with professionals from municipal interprofessional rehabilitation coordinating units formed the basis for the study. Data were analysed using systematic text condensation.

Results

A holistic view and strategically selected areas of expertise were found to characterise the work of occupational therapists in the municipal setting. A composed base of knowledge enables occupational therapists to be rehabilitators while working in collaboration with multiple professional partners.

Conclusions

Expertise in the areas of adaptation, assistive devices and cognition are considered to be valuable in acquired brain injury rehabilitation in a municipal setting. A practical synthesis of knowledge, transprofessional collaboration and role release enable the occupational therapist to act as a multifarious rehabilitator.

High Oxygen Exchange to Music Indicates Auditory Distractibility in Acquired Brain Injury: An fNIRS Study with a Vector-Based Phase Analysis

Attention deficits due to auditory distractibility are pervasive among patients with acquired brain injury (ABI). It remains unclear, however, whether attention deficits following ABI specific to auditory modality are associated with altered haemodynamic responses. Here, we examined cerebral haemodynamic changes using functional near-infrared spectroscopy combined with a topological vector-based analysis method. A total of thirty-seven participants (22 healthy adults, 15 patients with ABI) performed a melodic contour identification task (CIT) that simulates auditory distractibility. Findings demonstrated that the melodic CIT was able to detect auditory distractibility in patients with ABI. The rate-corrected score showed that the ABI group performed significantly worse than the non-ABI group in both CIT1 (target contour identification against environmental sounds) and CIT2 (target contour identification against target-like distraction). Phase-associated response intensity during the CITs was greater in the ABI group than in the non-ABI group. Moreover, there existed a significant interaction effect in the left dorsolateral prefrontal cortex (DLPFC) during CIT1 and CIT2. These findings indicated that stronger hemodynamic responses involving oxygen exchange in the left DLPFC can serve as a biomarker for evaluating and monitoring auditory distractibility, which could potentially lead to the discovery of the underlying mechanism that causes auditory attention deficits in patients with ABI.

The conflicted practice: Municipal occupational therapists' experiences with assessment of clients with cognitive impairments

BACKGROUND

The practice of Norwegian occupational therapists (OTs) in municipal practice is a little explored area and with the Coordination Reform Act from 2012, Norwegian OTs in municipal practice have received responsibilities concerning clients with cognitive impairments. The aim of this study was to explore municipal OTs experiences with assessment of clients with cognitive impairments.

METHOD

Fourteen individual interviews with OTs who worked with clients with cognitive impairments, were conducted. An inductive thematic analysis, using text condensation and coding, was performed.

RESULTS

The results revealed three themes; power of occupation, advantages and disadvantages of assessments used and the need for competencies within municipal services. The participants emphasized using observation in the assessment process and reflected on pros and cons of the standardized assessment tools they used. They expressed a need for competence development, although it was difficult to prioritize to do so.

CONCLUSION

This study illustrated a conflicted practice related to choices OTs make in their practices. They valued the importance of working occupation based, however, they chose to use impairment based standardized assessments. They expressed a need to engage in professional development, but due to heavy workloads, the limited power they experienced and lack of knowledge, this was difficult.

Assessment of clients with cognitive impairments: A survey of Norwegian occupational therapists in municipal practice

BACKGROUND

With the Coordination Reform Act initiated in 2012, Norwegian occupational therapists in municipal practice have been given responsibilities concerning clients with cognitive impairments. With emphasis on supporting best practice, the aim was to investigate the practice of Norwegian municipal occupational therapists (OTs) in their assessment of clients with cognitive impairments.

METHOD

An online questionnaire was used to collect data from 497 of 1367 OTs in Norwegian municipalities (RR = 36%) Results: The most frequently used methods were informal interviews (91%), observations (91%) and standardized assessments (73%). The most frequently used standardized assessments were the Clock Drawing test (60%) and the Mini Mental State Examination (MMSE 59%). The most common reasons for using standardized assessments were to get a better foundation for initiating interventions (74%), to get more reliable results (64%) and to measure the effect of interventions (47%). The most common reasons for not using standardized assessments were that they did not have competence (49%) or that they did not have access to the materials (40%).

CONCLUSION

The results indicate that there are challenges when it comes to the methods and standardized assessments used. These findings invite further research on enabling municipal OTs to move further towards evidence-based practice.

Outcomes of a multicomponent intervention on occupational performance in persons with unilateral acquired brain injury

Complications after unilateral acquired brain injury (ABI) can affect various areas of expertise causing (depending on the location of the lesion) impairment in occupational performance. The aim of this study was to analyze and compare the concepts of occupational performance and functional independence, both before and after a multicomponent intervention including occupational therapy, in persons with unilateral brain damage. This was a longitudinal quasi-experimental pretest post-test study in a sample of 58 patients with unilateral brain injury (28 with traumatic brain injury and 30 with ischemic stroke). The patients' level of independence was measured using the short version of the International Classification of Functioning, Disability and Health. We also measured quality of performance using the Assessment of Motor and Process Skills. The findings of this study showed that patients with injury in the right hemisphere improved more than those with left hemisphere damage (p<0.001). All the patients with ABI, especially those with right-sided injury, derived benefit from the multicomponent intervention, except in the area of motor skills. More research is needed on the specific techniques that might address such skills.

A qualitative evaluation of occupational therapy-led work rehabilitation for people with inflammatory arthritis: Perspectives of therapists and their line managers

INTRODUCTION

Occupational therapy-led work rehabilitation for employed people with inflammatory arthritis and work problems was piloted in five hospitals in the United Kingdom. This qualitative study explored the views of participating occupational therapists and their line managers about the work rehabilitation training received and conducting the intervention, with particular focus on the structured interview used, the Work Experience Survey - Rheumatic Conditions.

METHOD

Face-to-face semi-structured interviews were conducted with occupational therapists (n = 9), followed by telephone interviews with their line managers (n = 2). Interviews were audio-recorded, transcribed verbatim and thematically analysed by three researchers to maximize validity.

RESULTS

The main themes emerging from the occupational therapists' interviews were: varying levels of prior knowledge and experience of work rehabilitation, initial concerns about the feasibility of a lengthy work assessment in practice and increased confidence in delivering work rehabilitation as the study progressed. The line managers' interviews generated themes around the positive impact of the work rehabilitation training the occupational therapists received, and changes in their practice.

CONCLUSION

The Work Experience Survey - Rheumatic Conditions was considered a good choice of work assessment which can be implemented in practice. Once therapists had provided the work intervention several times, their confidence and skills increased.

Novel insights into the rehabilitation of memory post acquired brain injury: a systematic review

Objective: Acquired Brain Injury (ABI) frequently results in memory impairment causing significant disabilities in daily life and is therefore a critical target for cognitive rehabilitation. Current understanding of brain plasticity has led to novel insights in remediation-oriented approaches for the rehabilitation of memory deficits. We will describe 3 of these approaches that have emerged in the last decade: Virtual Reality (VR) training, Computer-Based Cognitive Retraining (CBCR) and Non-Invasive Brain Stimulation (NBS) and evaluate its effectiveness.

Methods: A systematic literature search was completed in regard to studies evaluating interventions aiming to improve the memory function after ABI. Information concerning study content and reported effectiveness were extracted. Quality of the studies and methods were evaluated.

Results: A total of 786 studies were identified, 15 studies met the inclusion criteria. Three of those studies represent the VR technique, 7 studies represent CBCR and 5 studies NBS. All 3 studies found a significant improvement of the memory function after VR-based training, however these studies are considered preliminary. All 7 studies have shown that CBCR can be effective in improving memory function in patients suffering from ABI. Four studies of the 5 did not find significant improvement of the memory function after the use of NBS in ABI patients.

Conclusion: On the basis of this review, CBCR is considered the most promising novel approach of the last decade because of the positive results in improving memory function post ABI. The number of studies representing VR were limited and the methodological quality low, therefore the results should be considered preliminary. The studies representing NBS did not detect evidence for the use of NBS in improving memory function.

How Occupational Therapists Engage Adults with Cognitive Impairments in Assessments

Introduction:

There is little discussion in the multidisciplinary literature about how to engage adults with cognitive impairments in health-related assessments. This qualitative descriptive study used semi-structured interviews to explore how nine occupational therapists working across a range of practice settings addressed this issue.

Method:

Interviews were digitally recorded and transcribed verbatim. Inductive analysis revealed themes, which were refined through an iterative process.

Findings:

The findings showed that the participants used individually developed strategies to engage clients in assessments. The first theme, ‘Managing a complex process’, described the steps used with clients and families to obtain informed consent, prepare for the assessment, and consider the impact of having a third party present. The second theme, ‘Recruiting cooperation’, addressed how the participants used their relationship with clients to recruit them to engage in the assessment.

Conclusion:

The findings provided a snapshot of processes employed in practice to determine the needs and capabilities of clients with cognitive impairments, and the compromises therapists make in relation to eliciting informed consent and the integrity of formal assessment tools. The findings have implications for the profession and further research.

Computer-based cognitive retraining for adults with chronic acquired brain injury: a pilot study

This study evaluated the effectiveness of a computer-based cognitive retraining (CBCR) program on improving memory and attention deficits in individuals with a chronic acquired brain injury (ABI). Twelve adults with a chronic ABI demonstrating deficits in memory and attention were recruited from a convenience sample from the community. Using a quasi-experimental one-group pretest-posttest design, a significant improvement was found in both memory and attention scores postintervention using the cognitive screening tool. This study supported the effectiveness of CBCR programs in improving cognitive deficits in memory and attention in individuals with chronic ABI. Further research is recommended to validate these findings with a larger ABI population and to investigate transfer to improvement in occupational performance that supports daily living skills.
