The role of cochlear and vestibular afferents in long-latency cervical vestibular evoked myogenic potentials.

International Journal of Epidemiology

To examine the origin of cervical vestibular evoked myogenic potential (cVEMP) late waves (n34-p44) elicited with air-conducted click stimuli.

Using a retrospective design, cVEMPs from normal volunteers were compared to those obtained from patients with vestibular and auditory pathologies.

(1) Normal volunteers (n = 56); (2) severe-to-profound sensorineural hearing loss (SNHL) with normal vestibular function (n = 21); (3) peripheral vestibular impairment with preserved hearing (n = 16); (4) total vestibulocochlear deficit (n = 23).

All normal volunteers had ipsilateral-dominant early p13-n23 peaks. Late peaks were present bilaterally in 78%. The p13-n23 response was present in all patients with SNHL but normal vestibular function, and 43% had late waves. Statistical comparison of these patients to a subset of age-matched controls showed no significant difference in the frequencies, amplitudes or latencies of their ipsilateral early and late peaks. cVEMPs were absent in all patients with vestibular impairment.

The presence of long-latency cVEMP waves was not dependent on the integrity of sensorineural hearing pathways, but instead correlated with intact vestibular function. This finding conflicts with the view that these late waves are cochlear in origin, and suggests that vestibular afferents may assume a more prominent role in their generation.

Adults' recollections of discussions with their audiologist: a qualitative study of what was and was not successfully communicated about listening difficulties.

International Journal of Epidemiology

Some adults experience challenges in successfully communicating their listening difficulties to their audiologist, and report feeling that they are not always listened to or understood. This project examined adults' recollections of discussions with their audiologist to explore (1) how adults report describing their listening difficulties and (2) information that adults report they do not communicate, or do not communicate successfully, to their audiologist.

Individual semi-structured interviews were conducted. Interview transcripts were analysed using a template analysis approach.

Fifteen adults who self-report listening difficulties, and who had previously consulted an audiologist.

Four themes were identified from adults' recollections of how they describe their listening difficulties: (1) situation or context of listening difficulties, (2) behavioural responses, (3) impacts of listening difficulties and (4) contributing factors. Adults report not always successfully communicating (1) emotional concerns and impacts, (2) descriptions of sound quality and (3) descriptions of changed listening experiences.

Results provide insights about the times when adults feel that communication with their audiologist is successful, or unsuccessful. The results are useful for informing interventions to help adults and audiologists communicate more effectively together. To further inform interventions, factors affecting adults' communication should be explored.

Generalizability of a Musculoskeletal Therapist Electronic Health Record for Modelling Outcomes to Work-Related Musculoskeletal Disorders.

Journal of Occupational Health Psychology

Electronic Health Records (EHRs) can contain vast amounts of clinical information that could be reused in modelling outcomes of work-related musculoskeletal disorders (WMSDs). Determining the generalizability of an EHR dataset is an important step in determining the appropriateness of its reuse. The study aims to describe the EHR dataset used by occupational musculoskeletal therapists and determine whether the EHR dataset is generalizable to the Australian workers' population and injury characteristics seen in workers' compensation claims.

Variables were considered if they were associated with outcomes of WMSDs and variables data were available. Completeness and external validity assessment analysed frequency distributions, percentage of records and confidence intervals.

There were 48,434 patient care plans across 10 industries from 2014 to 2021. The EHR collects information related to clinical interventions, health and psychosocial factors, job demands, work accommodations as well as workplace culture, which have all been shown to be valuable variables in determining outcomes to WMSDs. Distributions of age, duration of employment, gender and region of birth were mostly similar to the Australian workforce. Upper limb WMSDs were higher in the EHR compared to workers' compensation claims and diagnoses were similar.

The study shows the EHR has strong potential to be used for further research into WMSDs as it has a similar population to the Australian workforce, manufacturing industry and workers' compensation claims. It contains many variables that may be relevant in modelling outcomes to WMSDs that are not typically available in existing datasets.

Convergent validity of two adult self-report sensory scales: Comparing the Adolescent/Adult Sensory Profile and the Sensory Processing Measure 2-Adult Form.

Australian Occupational Therapy Journal

Occupational therapists use standardised scales and measures to assess an individual's sensory processing factors. To date, few studies have investigated the correlations between the Adolescent/Adult Sensory Profile (A/ASP) and the Sensory Processing Measure 2-Adult Form (SPM-2-Adult). The aim of the project is to investigate the association between the sensory processing factors measured by the A/ASP and SPM-2-Adult when completed by the same group of adult participants, with an additional research question investigating whether any significant differences existed between sensory processing scores based on participants' self-reported gender identity.

Forty-two adults aged 18-30 completed the A/ASP and the SPM-2-Adult. Associations between the A/ASP quadrant and the SPM-2-Adult subscales were examined using Spearman's rho correlation coefficients, and differences between participants based on their self-reported gender identity were investigated using Mann-Whitney U tests.

Statistically significant correlations were obtained between the A/ASP Low Registration, Sensory Sensitivity, and Sensation Avoiding quadrant subscales and all nine of the SPM-2-Adult subscales ranging from weak (rho = 0.342, p < 0.027) to strong (rho = 0.790, p < 0.001) correlations. The A/ASP Sensation Seeking quadrant subscale was only significantly correlated with the SPM-2-Adult Social Participation subscale (rho = -0.416, p = 0.006). Three subscales had statistically significant differences based on gender identity: SPM-2-Adult Vision (p = 0.007), SPM-2-Adult Sensory Total (p = 0.048), and A/ASP Sensory Sensitivity (p = 0.043).

Consumers and community members were not involved in the design, execution, or write-up of the study results.

The A/ASP and the SPM-2-Adult had several subscales that were significantly correlated with one another. Of note, significant associations were achieved between the A/ASP Low Registration, Sensory Sensitivity, and Sensation Avoiding quadrant subscales and all nine of the SPM-2-Adult subscales. These findings make a significant preliminary contribution to the psychometric body of evidence related to the sensory processing assessment of adults.

Cognitive strategies utilised by early learners when writing alphabet-letters from memory.

Australian Occupational Therapy Journal

Occupational therapy handwriting studies have shown cognitive instructional techniques are effective methods to assist beginning or challenged handwriters. However, information about how children's cognitive (thinking) skills impact their handwriting development is scarce. This study examined the cognitive strategy efficiency of early learners while writing the alphabet-letters from memory.

Participants included 408 mainstream children in their first two years of formal schooling (Year 1 and Year 2). Children were asked to write the 26-lowercase alphabet-letters from memory. Data were collected using alphabet-letters generated by the children and observation of their cognitive strategy use while writing. The measurement tool employed was the Perceive, Recall, Plan, and Perform (PRPP) System of Task Analysis (Stage Two).

The results found that Year 1 and Year 2 children had difficulties applying cognitive strategies across all four PRPP quadrants while writing the lowercase alphabet-letters from memory. Application of the cognitive strategies from the Plan and Recall quadrants showed the most inefficiencies. The lowest PRPP subquadrant scores were observed in Evaluating, Recall Facts, Sensing, and Programming. Except for the Attending subquadrant and the descriptor 'Regulates', Year 2 children were significantly better than Year 1 children at applying cognitive strategies from all other PRPP quadrants and subquadrants.

Research suggests that occupational therapists can best help children with handwriting difficulties by using a cognitive approach. This approach involves instructing children how to form letters correctly, encouraging self-evaluation, and providing opportunities to practice handwriting. However, the cognitive (thinking) skills required for children to write alphabet-letters accurately are not well understood. To investigate this, a study was conducted on 408 mainstream children in their first two years of formal schooling (Year 1 and Year 2). The study examined how accurately the children could write lowercase alphabet-letters from memory and which cognitive skills they used to do so. The cognitive skills investigated were related to attention, perception, recalling, planning, and performing. The assumption tested was that mistakes in correctly writing alphabet-letters could be attributed to difficulties in using these cognitive skills effectively. The study found that Year 1 and Year 2 children made errors in over half of the 26-lowercase alphabet-letters they wrote. The cognitive skills, which scored the lowest were children's ability to evaluate their writing, recall how and where to write letters, gather information from their vision, and think carefully to ensure accuracy while writing. This implied that these thinking skills had the most impact on the children's ability to write alphabet-letters correctly. More research is needed to confirm these findings and determine the reliability of the tool used in this study to measure the children's thinking skills.

Time use of patients in a secure forensic hospital: A mixed methods study.

Australian Occupational Therapy Journal

Forensic mental health services balance recovery-focussed therapy with risk management, which may limit opportunities for participation in meaningful occupation. Previous research describes forensic patients in secure settings participating mainly in passive leisure and sleep. This study aimed to use quantitative and qualitative evidence to investigate how patients in the sub-acute and rehabilitation units of an Australian forensic hospital perceive and use their time and to discuss how the findings compare with the previous study within the organisation, published in 2004.

An explanatory sequential mixed methods design was used with convenience sampling of patients and purposive sampling of staff. Patients completed time use diaries followed by semi-structured interviews. Staff perceptions were obtained via survey.

Seven male patients with a diagnosis of schizophrenia and five staff members (three occupational therapists and two nurses) participated. Time use diaries indicated patients spent most time in personal care, passive recreation, and leisure activities. Qualitative data illustrated patient time use was influenced by the individualised meaningfulness of activities. Patients drew meaning from past roles, personal interests/needs, and their goals for recovery. While patients had some choice over how time is spent and with whom they chose to engage, external factors such as staff/program availability prevented their having full control. Staff provided additional perspectives on the links between time use and recovery, identifying enablers and barriers to meaningful time use.

Patient time use has not changed significantly when compared to past research, although perceptions of time use are more future and recovery-focussed. The amount of time recorded in activities typically associated with recovery does not necessarily capture the quality and benefit of that time use. Patient participation continues to be influenced by broader systems.

Sports-Related Concussion in Collegiate Athletes: The Potential Benefits of Using Graded Neuropsychological Tests With High Ceilings.

Journal of Head Trauma Rehabilitation

Sports-related concussion management in collegiate athletes has been focused on return-to-play. However, resuming schoolwork without a gradual stepwise reintroduction contributes to symptom exacerbation, delayed recovery, and adverse academic performance. Return-to-learn guidelines are limited by a lack of sensitivity in methods monitoring cognitive function. This study evaluated 2 neuropsychological tests, the Sternberg test and the Paced Auditory Serial Addition Test (PASAT), with high ceilings for sensitivity to deficits in speed of information processing, cognitive efficiency, and complex attention.

The PASAT assesses complex attention. The Sternberg test examines processing speed and cognitive efficiency. Cognitive difficulty increases with progression through the tasks for both the PASAT and the Sternberg test. The mean outcome differences of the 3 groups (nonconcussed, acute, and chronic) across the 3 or 4 conditions (difficulty level) were measured with repeated-measures analysis of variance and subsequent pairwise comparison.

For processing speed (Sternberg reaction time), the acute group responded slower than the chronic group on the medium (P = .021, Bonferroni corrected) and hard difficulty tasks (P = .030, Bonferroni corrected). For cognitive efficiency (Sternberg reaction time variability), the acute group had increased reaction time variability compared with the chronic group on the medium difficulty task (P = .04, Bonferroni corrected). For complex attention (PASAT omissions), there was a difference between the acute and nonconcussed groups on the moderate-hard difficulty trial (P = .023, least significant difference [LSD] corrected) and between the acute and chronic groups for hard difficulty trial (P = .020, LSD corrected). The acute group performed worse, with progressively shorter interstimulus intervals.

Neuropsychological testing without ceiling effects can capture higher-level cognitive dysfunction and use of such tests can contribute to the understanding of how collegiate athletes are affected by SRC. Future studies can investigate optimal testing batteries that include neuropsychological testing with high ceilings and whether the pattern of performance has implications for the return-to-learn process after SRC in the college setting.

Fostering the discussion of planetary health in occupational therapy and physiotherapy.

Australian Occupational Therapy Journal

Occupational therapists and physiotherapists aim to promote health, prevent various diseases and help people in their rehabilitation processes. So far, there is a paucity of understanding of the big picture of how the new paradigm of planetary health (PH) is connected to the education and practice of these professionals.

This research aimed to address this gap by investigating and deploying a bibliometric analysis to elucidate the pivotal role of occupational therapists and physiotherapists in addressing PH challenges. The ultimate goal is to construct a comprehensive framework crosschecking the bibliometric analysis and the collection of 10 case studies selected by experts to outline how best practices in occupational therapy and physiotherapy, related to the three pillars of sustainability and the UN's Sustainable Development Goals (SDGs), can contribute to increasing PH.

The bibliometric analysis revealed four major research strands: 1) enhancing patient care and quality of life; 2) integrating sustainability in health care and rehabilitation; 3) professional development and clinical competence; and 4) evidence-based practice and quality improvement. Moreover, further temporal analysis revealed how the topic evolved, from advancing evidence-based practice and clinical effectiveness, exploring the strengthening of health care and person-centred practices, to connecting the topic to aspects also predicted by the SDGs, such as integrating environmental and climate concerns in therapy and addressing psychological and self-care impacts on health. The case studies confirmed this trend, and a framework of PH in occupational therapy and physiotherapy through the lens of the SDGs was developed to support future research and practitioners in advancing this research field.

Occupational therapists and physiotherapists are essential players in public health and can integrate sustainability at every level of practice, from using resources during therapy sessions to advocating for more sustainable lifestyles.

"Listen with your ears and eyes and heart and your minds and your soul": Implications for decolonising consultation and occupational therapy from case studies on "Closing the Gap" policy implementation.

Australian Occupational Therapy Journal

Including Aboriginal and Torres Strait Islander people and communities through consultation has been a key feature of policy implementation throughout the Australian Government's "Closing the Gap" (CTG) strategy. However, consultation often reinforces power imbalances between government and local community and can undervalue or marginalise Indigenous knowledge and leadership. Occupational therapy has a short history of examining colonial power structures within the profession, but there has been limited progress to decolonise consultation and practice.

Drawing on decolonising research methodology and positioned at the interface of knowledge, comparative case studies were used to understand policy implementation in two regions. In Shepparton, Victoria, CTG policy was implemented predominately through an Aboriginal Community Controlled Health Organisation, and in Southern Adelaide, South Australia, CTG policy was implemented through mainstream state government and non-government providers in the absence of a local Aboriginal-controlled organisation. Findings were examined critically to identify implications for occupational therapy.

Our case studies showed that policy stakeholders perceived consultation to be tokenistic and partnerships were viewed differently by Aboriginal and non-Indigenous participants. Participants identified the need to move beyond a rhetoric of "working with" Aboriginal and Torres Strait Islander people, to promote Aboriginal leadership and really listen to community so that policy can respond to local need. The findings of this research show that Aboriginal-controlled services are best positioned to conduct and respond to community consultation.

A decolonising approach to consultation would shift the status quo in policy implementation in ways that realign power away from colonial structures towards collaboration with Indigenous leadership and the promotion of Aboriginal-controlled services. There are lessons for occupational therapy from this research on policy implementation on authentic, decolonised consultation as a key feature of policy implementation. Shifting power imbalances through prioritising Indigenous leadership and honouring what is shared can drive change in CTG policy implementation processes and outcomes.

Reform and reverberation: Australian aged care policy changes and the unintended consequences for allied health.

Australian Occupational Therapy Journal

Allied health has a valuable role in providing services to people living in residential aged care. The recent Royal Commission into Aged Care Quality and Safety included several important recommendations relating to the nursing, personal care, and allied health workforce and the care that they provide. The purpose of this paper is to review these recommendations and the Australian Government's policy responses and explore the emerging changes in allied health service provision in residential aged care.

Data from the four available Quarterly Financial Reports from the 2022-2023 financial year were extracted and analysed in relation to staff costs and time per person per day across personal care, nursing, and allied health workers. Supplementary data sources including the 2020 Aged Care Workforce Census were accessed to provide contextual data relating to individual allied health professions, including occupational therapy.

The analysis shows a modest increase in median registered nurse minutes per person per day, and cost per person per day, from the first to second quarter, and again in the third and fourth. By contrast, median time and cost for allied health declined. From 5.6 minutes per person per day in the first quarter, reported allied health minutes fell to 4.6 minutes per person per day in the second quarter, an 18% decrease, and by the fourth quarter was 4.3 minutes per person per day. This is just over half the Australian average of 8 minutes reported to the RCACQS in 2019.

Under recent residential aged care reforms, aged care providers have regulatory incentives to concentrate their financial resources on meeting the mandated care hours for registered nurses, enrolled nurses, personal care workers, and assistants in nursing. These same reforms do not mandate minutes of allied health services. Although providers of residential aged care in Australia continue to employ and value allied health, we argue that mandating care minutes for personal and nursing care without mandating the provision of allied health creates a perverse incentive whereby access to allied health services is unintentionally reduced.

Occupational balance and stroke impact among community-dwelling stroke survivors 65 years or older: a cross-sectional study.

Australian Occupational Therapy Journal

Occupational balance has been investigated in different populations but less in stroke survivors. Previous studies have focussed on occupational balance among stroke survivors of working age (15-64 years of age), showing they did not perceive they had occupational balance. There is, therefore, a lack of knowledge of how older stroke survivors perceive their occupational balance. The aims of this study were to describe occupational balance in community-dwelling stroke survivors 65 years or older and to investigate if there were any associations between their perceived stroke impact and occupational balance.

A cross-sectional study was performed with 58 stroke survivors, with a median age of 75 years at stroke onset and a median time since stroke onset of 11 months. The participants were recruited from a local stroke register and answered questionnaires on occupational balance and stroke impact. Data were analysed with descriptive statistics, correlations and logistic regression.

The participants had a median score of 29 (min 12 to max 33), indicating a very high occupational balance, a low stroke impact, and a good recovery (median 82.5; min 0 to max 100). An association between participation and occupational balance (OR 1.13; 95% CI 1.04-1.23) was found.

The stroke survivors perceived a low stroke impact and a high occupational balance. It is possible that older community-dwelling stroke survivors, of whom many have retired, juggle less occupations leaving them with more time to engage in those occupations they want to, leading to a better occupational balance.
