- Description: Background: An essential factor in the validity of motor evoked potential (MEP)s recorded by transcranial magnetic stimulation (TMS) over multiple times is their test-retest reliability which to a large extent depends on the accuracy and competence of the assessor (intra-rater reliability). However, intra-rater reliability is infrequently reported in TMS studies suggesting that this is rarely done. Objectives: This study was conducted to determine the intra-rater within and between-session reliability of a newly trained TMS assessor prior to a main TMS study and report on the methodology used to encourage similar practice. Methods: Fourteen (10 males, 4 females; mean age: 32 ± 5.8 years) participants took part in the study. Motor evoked potentials were elicited from a relaxed, right first dorsal interosseous (FDI) muscle three times (T1, T2 and T3) across two testing sessions at least 48 hours apart. During the first session, MEPs were recorded twice (T1 and T2) within an interval of 20 minutes to determine the within (intra) session reliability of the assessor. During the second session, a single measurement was carried out (T3) which was compared to T1 to determine the inter-session reliability. Results: Repeated measure analysis of variance (ANOVA) did not reveal significant difference in the amplitude of the MEPs obtained across the three time periods (P = 0.196) demonstrating agreement in the MEPs and hence the reliability of the assessor. Additionally, the intraclass correlation coefficient (ICC) between T1 and T2; and T1 and T3 were 0.952 (P < 0.001) and 0.833 (P = 0.001) respectively further indicating the within and between sessions reliability of the assessor. Conclusions: The agreement between the three measured MEPs amplitude and the significant ICC demonstrates the reliability of the assessor in this study to use TMS for research. We suggest that the intra-rater reliability of new TMS operators should be established using the methodology in this report prior to main TMS studies. © 2023, Salihu et al.

- Description: Multiple sclerosis (MS) is a chronic autoimmune disease characterized by inflammation, demyelination of axons, and oligodendrocyte loss in the central nervous system. This leads to neurological dysfunction, including hand impairment, which is prevalent among patients with MS. However, hand impairment is the least targeted area for neurorehabilitation studies. Therefore, this study proposes a novel approach to improve hand functions compared to current strategies. Studies have shown that learning new skills in the motor cortex (M1) can trigger the production of oligodendrocytes and myelin, which is a critical mechanism for neuroplasticity. Transcranial direct current stimulation (tDCS) has been used to enhance motor learning and function in human subjects. However, tDCS induces non-specific effects, and concurrent behavioral training has been found to optimize its benefits. Recent research indicates that applying tDCS during motor learning can have priming effects on the long-term potentiation mechanism and prolong the effects of motor training in health and disease. Therefore, this study aims to assess whether applying repeated tDCS during the learning of a new motor skill in M1 can be more effective in improving hand functions in patients with MS than current neurorehabilitation strategies. If this approach proves successful in improving hand functions in patients with MS, it could be adopted as a new approach to restore hand functions. Additionally, if the application of tDCS demonstrates an accumulative effect in improving hand functions in patients with MS, it could provide an adjunct intervention during rehabilitation for these patients. This study will contribute to the growing body of literature on the use of tDCS in neurorehabilitation and could have a significant impact on the quality of life of patients with MS. 2023 Zoghi and Jaberzadeh.

- Description: Growing cultural and linguistic diversity globally is increasingly requiring speech pathologists to provide effective and equitable aphasia rehabilitation to clients with whom they do not share a language. Little is known about how rehabilitation is being adapted and provided when a language mismatch arises between the therapist and the client. This scoping review aims to systematically map the evidence related to aphasia rehabilitation when the speech pathologist and the client do not share a language. A comprehensive search was conducted in September 2020. Twenty studies comprising surveys and/or interviews and descriptive publications were reviewed. Speech pathologists frequently report a lack of confidence, skill, and preparation to work with culturally and linguistically diverse clients with aphasia. Furthermore, there is a shortage of published evidence, guidelines, resources, and access to interpreters to support their practice. Further research is needed into aphasia rehabilitation when there is no shared language between client and speech pathologist, with particular attention to the therapy approach selected and adaptations required for the target language and culture. Information is needed concerning how the speech pathologist and interpreter work together, as well as the experiences of interpreters and people with aphasia and their families.

- Description: Expert sport performers cope with a multitude of visual information to achieve precise skill goals under time stress and pressure. For example, a major league baseball or cricket batter must read opponent variations in actions and ball flight paths to strike the ball in less than a second. Crowded playing schedules and training load restrictions to minimise injury have limited opportunity for field-based practice in sports. As a result, many sports organisations are exploring the use of virtual reality (VR) simulators. Whilst VR synthetic experiences can allow greater control of visual stimuli, immersion to create presence in an environment, and interaction with stimuli, compared to traditional video simulation, the underpinning mechanisms of how experts use visual information for anticipation have not been properly incorporated into its content design. In themes, this opinion article briefly explains the mechanisms underpinning expert visual anticipation, as well as its learning and transfer, with a view that this knowledge can better inform VR simulator content design. In each theme, examples are discussed for improved content design of VR simulators taking into consideration its advantages and limitations relative to video simulation techniques. Whilst sport is used as the exemplar, the points discussed have implications for skill learning in other domains, such as military and law enforcement. It is hoped that our paper will stimulate improved content design of VR simulators for future research and skill enhancement across several domains. © 2022, The Author(s).

- Description: Background: Occupational therapy competency standards provide an evidence-base to inform clinical best practice, however it is not known whether education about competency standards will increase occupational therapists’ adherence to their use. Aims/objectives: To investigate if education about the ‘Australian Competency Standards for Occupational Therapy Driver Assessors’ leads to increased adherence to the competency standards in the clinical practice of occupational therapy driver assessors. Materials and methods: A mixed methods multiple case study design was used to evaluate 5 occupational therapy driver assessors’ adherence to the competency standards. An audit of 25 client files and interviews were conducted to evaluate practice against the competency standards prior to an education session, followed by an audit of a further 25 files, interview and feedback after education. Results: Qualitative and quantitative analyses suggest that education about the ‘Australian Competency Standards for Occupational Therapy Driver Assessors’ was associated with increased adherence to the competency standards in clinical practice. The results also support the use of competency standards in clinical practice. Conclusions and significance: Competency standards can be used to inform and guide clinical practice, and individualised education and feedback of practice against the competency standards can increase occupational therapists’ adherence to these standards. © 2022 Scandinavian Journal of Occupational Therapy Foundation.

- Description: Background: Previous studies have examined the relationship between external load and creatine-kinase (CK) response at the team level. This study aimed to build individualized CK prediction models for elite youth national team soccer players. Hypothesis: The CK response of youth soccer players can be categorized as being sensitive to micromovements (MM), high-velocity (HV) parameters, or the combination of both, measured during training sessions and matches. Study Design: Prospective cohort study. Level of Evidence: Level 4. Methods: A total of 25 U16-U17 youth national team soccer players were monitored during training sessions and matches using global positioning system (GPS) units. Individual CK values were measured every morning from whole blood. The data set consisted of 57 ± 17 individual datapoints per player. Individual prediction models were used to examine the relationship between external load and consecutive CK changes. Numerous models were built for each player using MM, HV parameters, or the combination of both. The performance of the models was described by the R2 and the root mean square error (RMSE, U/l for CK values). Results: The MM models were superior for 8 players (R2 = 0.68; RMSE = 113 U/l), followed by HV (8 players; R2 = 0.69; RMSE = 88 U/l) and the combined models (2 players; R2 = 0.64; RMSE = 141 U/l). For the remaining 7 players, the R2 of the models was <0.5. The recovery time between efforts was more important in the HV model. Conclusion: Players could be categorized on sensitivity to MM, HV movements, or the combination of both. Clinical Relevance: These findings can be used to individualize postmatch recovery strategies and to optimize weekly training periodization to maximize match performance. © 2022 The Author(s).

- Description: Currently, little is known about the lived experiences of children who participate in yoga, particularly using their own words. This study provides insights into how young children aged 6 to 10 years old were able to understand their bodies within a yoga space. The purpose of this study was to investigate young children’s lived experiences of yoga through qualitative interviews. Parents of children engaged in yoga were also interviewed to gain a sense of their point of view about the experiences of yoga for their children. Results indicated yoga had assisted children to find, and express joy, and fun by moving their bodies into different shapes. The physical and psychological difficulty of some of the yoga shapes assisted children to develop a persistent mind-set which enabled them to transfer knowledge to different contexts, such as difficulties at school, and finding ways to relax, and be with themselves. Yoga as an activity after-school develops strategies such as resilience, and assists in other contexts such as school, and family. The parents’ described how they were looking for techniques to help calm their children, and how challenging this was with the constant stimulation of everyday activities. The findings suggest that yoga may have a place in the school curriculum for the purpose of teaching students’ simple coping skills when experiencing feelings of stress, and anxiety, and assist with controlling their behavior. © 2022 Taylor & Francis.

- Description: Extended reality is an umbrella term used to describe three computer-generated technologies including virtual reality, augmented reality and mixed reality. Extended reality is an emerging technology that has been utilised in many high-performance domains including psychology, medicine and the military, with the aim of enhancing perceptual-cognitive skills and motor skills. However, the use of extended reality in sport, particularly at the elite level, has only recently started to receive attention. While the growth of extended reality technology continues to accelerate at a rapid rate, empirical evidence aimed at understanding how these devices can best be applied in high-performance sport has not followed suit. Therefore, the purpose of this review is to provide clarity for high-performance sport organisations, researchers, sport scientists, coaches and athletes about the current state of extended reality technology and how it has been utilised in sport. In doing so, we first define and give examples of the types of extended reality technology including virtual reality, augmented reality and mixed reality that are available at the present time. Second, we detail how skill acquisition principles underpinned by the theoretical framework of ecological dynamics can be used to help inform the design and assessment of extended reality training tools. Third, we describe how extended reality has been utilised in sport, including how extended reality tools have been assessed for their level of representativeness, and the effectiveness of extended reality training interventions for improving perceptual-cognitive skills and motor skills. Finally, we discuss the future utilisation of extended reality in sport, including the key learnings that can be drawn from other domains, future research directions, practical applications and areas for consideration related to the use of extended reality for training skills in sport. © 2022, The Author(s).

- Description: Background: As basketball match-play requires players to possess a wide range of physical characteristics, many tests have been introduced in the literature to identify talent and quantify fitness in various samples of players. However, a synthesis of the literature to identify the most frequently used tests, outcome variables, and normative values for basketball-related physical characteristics in adult male basketball players is yet to be conducted. Objective: The primary objectives of this systematic review are to (1) identify tests and outcome variables used to assess physical characteristics in adult male basketball players across all competition levels, (2) report a summary of anthropometric, muscular power, linear speed, change-of-direction speed, agility, strength, anaerobic capacity, and aerobic capacity in adult male basketball players based on playing position and competition level, and (3) introduce a framework outlining recommended testing approaches to quantify physical characteristics in adult male basketball players. Methods: A systematic review of MEDLINE, PubMed, SPORTDiscus, Scopus, and Web of Science was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify relevant studies. To be eligible for inclusion, studies were required to: (1) be original research articles; (2) be published in a peer-reviewed journal; (3) have full-text versions available in the English language; and (4) include the primary aim of reporting tests used and/or the physical characteristics of adult (i.e., ≥ 18 years of age) male basketball players. Additionally, data from the top 10 draft picks who participated in the National Basketball Association combined from 2011–12 to 2020–21 were extracted from the official league website to highlight the physical characteristics of elite 19- to 24-year-old basketball players. Results: A total of 1684 studies were identified, with 375 being duplicates. Consequently, the titles and abstracts of 1309 studies were screened and 231 studies were eligible for full-text review. The reference list of each study was searched, with a further 59 studies identified as eligible for review. After full-text screening, 137 studies identified tests, while 114 studies reported physical characteristics in adult male basketball players. Conclusions: Physical characteristics reported indicate a wide range of abilities are present across playing competitions. The tests and outcome variables reported in the literature highlight the multitude of tests currently being used. Because there are no accepted international standards for physical assessment of basketball players, establishing normative data is challenging. Therefore, future testing should involve repeatable protocols that are standardised and provide outcomes that can be monitored across time. Recommendations for testing batteries in adult male basketball players are provided so improved interpretation of data can occur.

Conclusions: Physical characteristics reported indicate a wide range of abilities are present across playing competitions. The tests and outcome variables reported in the literature highlight the multitude of tests currently being used. Because there are no accepted international standards for physical assessment of basketball players, establishing normative data is challenging. Therefore, future testing should involve repeatable protocols that are standardised and provide outcomes that can be monitored across time. Recommendations for testing batteries in adult male basketball players are provided so improved interpretation of data can occur.

- Description: Objective: To determine whether high or low adiposity is associated with youth sport-related injury.Data Sources: Ten electronic databases were searched to identify prospective studies examining the association between adiposity [body mass index (BMI) or body fat] and a future time-loss or medical attention sport-related musculoskeletal injury or concussion in youth aged 20 years and younger. Two independent raters assessed the quality (Downs and Black criteria) and risk of bias (Joanna Briggs Institute Critical Appraisal Tool). Random-effects meta-analyses were used to calculate pooled odds ratio [95% confidence interval (CI)] of injury.Main Results: Of 11 424 potentially relevant records, 38 articles were included with 17 eligible for meta-analyses. In qualitative synthesis, no clear association was identified between adiposity and any sport injury; however, 16/22 studies identified high adiposity as a significant risk factor for lower-extremity injury. Meta-analyses revealed higher BMI in youth with any sport-related injury and lower BMI in youth who developed a bone stress injury (BSI) compared with noninjured controls. The pooled OR (95% CI) examining the association of BMI and injury risk (excluding bone injury) was 1.18 (95% CI: 1.03-1.34). A major source of bias in included articles was inconsistent adjustment for age, sex, and physical activity participation.Conclusions: Level 2b evidence suggests that high BMI is associated with greater risk of youth sport injury, particularly lower-extremity injury and excluding BSI or fracture. Although pooled mean differences were low, anthropometric risk of injury seems to be dependent on type and site of injury in youth sport. © 2021 Wolters Kluwer Health, Inc.

- Description: The detection of antinuclear autoantibody (ANA) is dependent on many factors and varies between the populations. The aim of the study was first to assess the prevalence of ANA in the Polish adult population depending on age, sex and the cutoff threshold used for the results obtained. Second, we estimated the occurrence of individual types of ANA-staining patterns. We tested 1731 patient samples using commercially available IIFA using two cutoff thresholds of 1:100 and 1:160. We found ANA in 260 participants (15.0%), but the percentage of positive results strongly depended on the cutoff level. For a cutoff threshold 1:100, the positive population was 19.5% and for the 1:160 cutoff threshold, it was 11.7%. The most prevalent ANA-staining pattern was AC-2 Dense Fine speckled (50%), followed by AC-21 Reticular/AMA (14.38%) ANA more common in women (72%); 64% of ANA-positive patients were over 50 years of age. ANA prevalence in the Polish population is at a level observed in other highly developed countries and is more prevalent in women and elderly individuals. To reduce the number of positive results released, we suggest that Polish laboratories should set 1:160 as the cutoff threshold. © 2021, The Author(s). **Please note that there are multiple authors for this article therefore only the name of the first 30 including Federation University Australia affiliate “Fadi Charchar" is provided in this record**

- Description: Tram driving is a safety critical task where work-related musculoskeletal disorders (WRMSDs) and injuries are associated with interacting occupational design factors over time. These interactions then carry implications for workforce retention, public safety, workplace relations and supports. To better understand such interactions, this study used thematic networks and system dynamics (causal loop diagrams) analysis with the aim to unearth a global theme underscoring occurrence of WRMSDs, and describe the factors influencing the system dynamics of WRMSD occurrence in tram drivers. Building on earlier work focused on occupational participation, secondary analysis of driver interviews (n = 13) and driving observations (n = 11) produced thematic network and causal loop models of risk factors that highlighted an Injury by Design problem structure as a global theme. Research targeting organisational culture, human factors, and design standards is needed to minimise WRMSDs risk in tram drivers. © 2021 The Authors

- Description: Background: Menstrual hygiene management is a global public health issue that requires local and individualized support to reduce activity limitations and enable safe, independent task performance for people with impaired body functions. Aim: How do women with blindness or low vision self-manage their menstrual hygiene to promote independence, and what do they recommend occupational therapists incorporate in education for young women when working in this field? Methods: Phenomenological design revealing lived experience expertise. Semi-structured interviews were conducted with six women who are blind or have low vision aged 16–70 in Australia. The resulting data transcripts were coded and analyzed thematically using the Person-Environment Occupation Performance Model as an organizing framework. Results: Participants reported a range of personal (touch) and organizational strategies relying on environmental cues such as regular times for changing sanitary items, lining up pads using underwear seams and wearing dark clothing to disguise leaks. Participants suggested that group occupational therapy education sessions be used to promote self-management. Conclusions and significance: The lived experience of women who successfully self-manage menstrual hygiene with blindness or low vision has generated evidence to inform the development of therapist-mediated interventions and resources that could be applied with women across a range of clinical populations. © 2021 Crown Copyright in the Commonwealth Government of Australia.

- Description: •The occurrence of urinary incontinence was higher in women with breast cancer.•Women with breast cancer experienced higher distress and impact of urinary symptoms.•Routine screening and offer of treatment for urinary symptoms may be indicated. One of the sequalae of breast cancer treatments may be pelvic floor (PF) dysfunction such as urinary incontinence (UI), faecal incontinence (FI), and pelvic organ prolapse (POP). The aim of this study was to compare the occurrence and related distress and impact of PF dysfunction between women with and without breast cancer. Women with and without breast cancer participated in this cross-sectional study. The Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire were used to quantify the prevalence and related distress, and impact of PF dysfunction. Factors associated with PF outcomes were examined using logistic and linear regressions while controlling for known risk factors for PF dysfunction (age, body mass index, and parity). 120 women with breast cancer, and 170 women without breast cancer responded. The occurrence of any type of UI was higher in women with breast cancer than women without breast cancer (percentage difference=17% 95% CI: 7, 29). Women with breast cancer experienced higher impact of urinary symptoms (mean difference=18.2 95% CI: 8.9, 27.7) compared to those without. Multivariable analysis indicated that having breast cancer (β 0.33 95%CI: 0.08, 0.51) was the strongest predictor of greater impact of urinary symptoms. Women with breast cancer reported a higher occurrence and impact of urinary symptoms than women without breast cancer. While further studies are required to confirm our findings, routine screening and offering treatment for urinary symptoms may be indicated for women with breast cancer.

The search was conducted in August 2021 using the Joanna Briggs framework to scope and map the literature and research activity. Using strict criteria, 7 online databases, grey literature and reference lists were searched for resources written or published in the last 15 years (2006–2021). Relevant sources were shortlisted and assessed by the two authors. Six sources met the criteria for inclusion in this review. In total, four educational programs are described and discussed. The results identify four sexuality and respectful relationship programs that met screening criteria: (1) “Telling it like it is!”, (2) “Sexual Lives and Respectful Relationships”, (3) “Talking about sex and relationships: the views of young people with learning disabilities”, and (4) “Health, Safety & Sexuality Training for You & Me”. Peer-educators experienced increased confidence and feelings of empowerment, while people without an intellectual disability reported a greater understanding of the challenges and experiences of people with a disability. The use of peer educators to deliver sexuality and respectful relationship education for people with intellectual disability is a promising education model with multiple potential benefits for participants. However, more research is needed to understand the consequences and limitations of such programs. © 2022, Crown.

- Description: Background: Previous studies have examined the training load relative to match load in club settings. The aims of this study were to (1) quantify the external training load relative to match load in days before a subsequent international game and (2) examine the cumulative training load in relation to match load of U-17 national team field soccer players. Hypothesis: Volume and intensity load parameters will vary between trainings; the farthermost trainings have the highest load gradually decreasing toward the match. Study Design: Prospective cohort study. Level of Evidence: Level 4. Methods: External training load data were collected from 84 youth national team players using global positioning technology between 2016 and 2020. In the national team setting, training load data were obtained from 3 days before the actual match day (MD-3, MD-2, MD-1 days) and analyzed with regard to the number of days up to the game. Volume and intensity parameters were calculated as a percentage of the subsequent match load. Results: Significant differences were found between MD-1 and MD-2, as well as between MD-1 and MD-3 for most volume parameters (P < 0.01; effect sizes [ESs] 0.68-0.99) and high-intensity distance (P < 0.002; ES 0.67 and 0.73) and maximum velocity (P < 0.002; ES 0.82) as intensity parameters. Most cumulative values were significantly different from total duration (P < 0.001, common language ES 0.80-0.96). Conclusion: The training volume gradually decreased as match day approached, with the highest volume occurring on MD-3. Intensity variables, such as maximum velocity, high-intensity accelerations, and meterage per minute were larger in MD-1 training relative to match load. Training volume was lowest in MD-1 trainings and highest in MD-3 trainings; intensity however varies between training days. Clinical Relevance: The findings of this study may help to understand the special preparational demands of international matches, highlighting the role of decreased training volume and increased intensity. © 2021 The Author(s).

- Description: Objective: The purpose of this study was to determine the safety and feasibility of subacute upper limb resistance exercise on sternal micromotion and pain and the reliability of sternal ultrasound assessment following cardiac surgery via median sternotomy. Methods: This experimental study used a pretest-posttest design to investigate the effects of upper limb resistance exercise on the sternum in patients following their first cardiac surgery via median sternotomy. Six bilateral upper limb machine-based exercises were commenced at a base resistance of 20 lb (9 kg) and progressed for each participant. Sternal micromotion was assessed using ultrasound at the mid and lower sternum at 2, 8, and 14 weeks postsurgery. Intrarater and interrater reliability was calculated using intraclass correlation coefficients (ICCs). Participant-reported pain was recorded at rest and with each exercise using a visual analogue scale. Results: Sixteen adults (n = 15 males; 71.3 [SD = 6.2] years of age) consented to participate. Twelve participants completed the study, 2 withdrew prior to the 8-week assessment, and 2 assessments were not completed at 14 weeks due to assessor unavailability. The highest median micromotion at the sternal edges was observed during the bicep curl (median = 1.33 mm; range = -0.8 to 2.0 mm) in the lateral direction and the shoulder pulldown (median = 0.65 mm; range = -0.8 to 1.6 mm) in the anterior-posterior direction. Furthermore, participants reported no increase in pain when performing any of the 6 upper limb exercises. Interrater reliability was moderate to good for both lateral-posterior (ICC = 0.73; 95% CI = 0.58 to 0.83) and anterior-posterior micromotion (ICC = 0.83; 95% CI = 0.73 to 0.89) of the sternal edges. Conclusion: Bilateral upper limb resistance exercises performed on cam-based machines do not result in sternal micromotion exceeding 2.0 mm or an increase in participant-reported pain. Impact: Upper limb resistance training commenced as early as 2 weeks following cardiac surgery via median sternotomy and performed within the safe limits of pain and sternal micromotion appears to be safe and may accelerate postoperative recovery rather than muscular deconditioning. © 2022 The Author(s).

- Description: The rehabilitation strategies used by occupational therapy driver assessors with older drivers with age-related decline or health conditions are not well understood. The objective of the study was to describe driver rehabilitation interventions used by Australian driver assessors, identify factors that guide rehabilitation choices, and identify barriers and facilitators encountered. An online survey was emailed to 300 driver assessors. Descriptive statistics were used to summarize and to rank order participant responses. A total of 148 respondents selected from a combined total of 655 interventions. The four most common rehabilitation methods were (a) graded driving (18%, n = 118), (b) practicing specific maneuvers (17.7%, n = 116), (c) using a modified vehicle (16.9%, n = 111), and (d) graded driving in local areas only (15.1%, n = 99). The most common barrier limiting driver rehabilitation was cost (M = 2.92, SD = 1.24). The most frequently used driver rehabilitation method was on-road training. Practice can be enhanced by collating and evaluating resources, and ensuring effective interventions are more accessible. © The Author(s) 2021.
