Unintended consequences - A qualitative exploration of baseline testing in community rugby concussion management.

OBJECTIVES: Understanding key stakeholders' perceptions around the value of baseline testing, as well as barriers or facilitators experienced as part of the process, may assist with the decision-making process of whether to implement baseline testing in community sport. This study explored coaches', players' and physiotherapists' perceptions of the perceived value, barriers and facilitators of baseline testing as part of New Zealand Rugby's (NZR) community concussion initiative. DESIGN: The study employed a pragmatic, qualitative descriptive design. METHODS: Semi-structured interviews were used to explore participants' perceptions. In total, 73 individual interviews were conducted. The sample consisted of 36 players, 13 coaches and 24 physiotherapists involved in NZR's concussion management pathway. Interviews were audio-recorded and transcribed verbatim. Data were analysed using thematic analysis. RESULTS: In terms of perceived value, baseline testing was reported to play a role in i) facilitating a positive concussion culture; ii) positive perceptions of rugby and player safety and iii) enhancing concussion management as part of the pathway. Barriers and facilitators of the baseline testing process included i) stakeholder buy-in as critical driver of the process and ii) contextual and operational factors. Although contextual and operational challenges exist, these participants, as key stakeholders in the process, perceived the value of baseline testing to be more important than the barriers experienced. CONCLUSIONS: The value of baseline testing extends beyond concussion assessment and management, by enhancing community concussion awareness, attitudes and player safety. The findings of this study may assist in the decision-making process around inclusion of pre-season baseline testing in community rugby.

Strategies for knee stabilising and pivot-shift avoidance in a step-down and cross-over task observed sub-acutely after anterior cruciate ligament reconstruction.

BACKGROUND: Individuals with a recent anterior cruciate ligament reconstruction may demonstrate an altered movement strategy for protecting the knee and maintaining stability. Altered knee movement might lead to abnormal intra-articular load, potentially contributing to early knee osteoarthritis onset. A protective strategy may be particularly evident during active tasks that induce a pivot-shift manoeuvre, such as a step-down and cross-over task. In this study, we investigated whether knee joint mechanics and muscle activity differed between participants early (∼3 months) following reconstruction (n = 35) to uninjured controls (n = 35) during a step-down and cross-over task with a 45° change-of-direction. METHODS: We used motion capture, force plates and surface electromyography to compare time-normalised curves of sagittal and transverse-plane knee mechanics and muscle activity during the cross-over phase between groups using functional t-tests. We also compared knee mechanics between sides within the injured group and compared discrete outcomes describing the cross-over phase between groups. FINDINGS: Compared to controls, the injured participants had greater knee flexion angle and moment, lower internal rotation moment, more preparatory foot rotation of the pivoting leg, a smaller cross-over angle, and a longer cross-over phase for both the injured and uninjured sides. The injured leg also had greater biceps femoris and vastus medialis muscle activity compared to controls and different knee mechanics than the uninjured leg. INTERPRETATION: Individuals with anterior cruciate ligament reconstruction showed a knee-stabilising and pivot-shift avoidance strategy for both legs early in rehabilitation. These results may reflect an altered motor representation and motivate considerations early in rehabilitation.

Quest for clarity: investigating concussion-related responsibilities across the New Zealand Rugby Community System.

There is a growing concern around concussions in rugby union, at all levels of the game. These concerns highlight the need to better manage and care for players. However, consistency around concussion-related responsibilities of stakeholders across the community rugby system remains challenging. Taking a systems thinking approach, this pragmatic, qualitative descriptive study explored key stakeholder groups within New Zealand's community rugby system's perceptions of their own and others' concussion-related responsibilities. Participants included players from schools and clubs, coaches, parents, team leads and representatives from four provincial unions. A total of 155 participants (67 females and 88 males) were included in the study. Focus groups and individual interviews were conducted. Thematic content analysis was used to analyse data. Thirty concussion-related responsibilities were identified. These responsibilities were contained within four themes: (1) policies and support (responsibilities which influence policy, infrastructure, human or financial resources); (2) rugby culture and general management (responsibilities impacting players' welfare and safety, attitudes and behaviour, including education, injury reporting and communication); (3) individual capabilities (responsibilities demonstrating knowledge and confidence managing concussion, leadership or role/task shifting) and (4) intervention following a suspected concussion (immediate responsibilities as a consequence of a suspected concussion). The need for role clarity was a prominent finding across themes. Additionally, injury management initiatives should prioritise communication between stakeholders and consider task-shifting opportunities for stakeholders with multiple responsibilities. How concussions will realistically be managed in a real-world sports setting and by whom needs to be clearly defined and accepted by each stakeholder group. A 'framework of responsibilities' may act as a starting point for discussion within different individual community rugby contexts on how these responsibilities translate to their context and how these responsibilities can be approached and assigned among available stakeholders.

Clinicians' perspectives on planned interventions tested in the Otago MASTER feasibility trial: an implementation-based process evaluation study.

OBJECTIVES: This study reports a process evaluation of the Otago MASTER (MAnagement of Subacromial disorders of The shouldER) feasibility trial. This mixed-methods, process evaluation study was conducted parallel to the Otago MASTER feasibility trial. Our aims were to investigate: (1) supervised treatment fidelity of the interventions and (2) clinicians' perceptions of the trial interventions through a focus group. DESIGN: Nested process evaluation study using a mixed-methods approach. SETTING: Outpatient clinic. PARTICIPANTS: Five clinicians (two men, three women) aged 47-67 years, with clinical experience of 18-43 years and a minimum of postgraduate certificate training, were involved with the delivery of interventions within the feasibility trial. We assessed treatment fidelity for supervised exercises through audit of clinicians' records and compared those with the planned protocol. Clinicians took part in a focus group that lasted for approximately 1 hour. The focus group was transcribed verbatim and focus group discussion was analysed thematically using an iterative approach. RESULTS: The fidelity score for the tailored exercise and manual therapy intervention was 80.3% (SD: 7.7%) and for the standardised exercise intervention, 82.9% (SD: 5.9%). Clinicians' perspectives about the trial and planned intervention were summarised by one main theme 'conflict experienced between individual clinical practice and the intervention protocol', which was supported by three subthemes: (1) programme strengths and weaknesses; (2) design-related and administrative barriers; and (3) training-related barriers. CONCLUSION: This mixed-methods study assessed supervised treatment fidelity of interventions and clinicians' perceptions on planned interventions tested in the Otago MASTER feasibility trial. Overall, treatment fidelity was acceptable for both intervention arms; however, we observed low fidelity for certain domains within the tailored exercise and manual therapy intervention. Our focus group identified several barriers clinicians faced while delivering the planned interventions. Those findings are of relevance for planning the definite trial and for researchers conducting feasibility trials. TRIAL REGISTRATION NUMBER: ANZCTR: 12617001405303.

Test-Retest Reliability of a Passive Joint Position Sense Test After ACL Reconstruction: Influence of Direction, Target Angle, Limb, and Outcome Measures.

Background: The joint position sense (JPS) is an element of proprioception and defined as an individual's ability to recognize joint position in space. The JPS is assessed by measuring the acuity of reproducing a predetermined target angle. The quality of psychometric properties of knee JPS tests after anterior cruciate ligament reconstruction (ACLR) is uncertain. Purpose/Hypothesis: The purpose of this study was to evaluate the test-retest reliability of a passive knee JPS test in patients who underwent ACLR. We hypothesized that the passive JPS test would produce reliable absolute error, constant error, and variable error estimates after ACLR. Study Design: Descriptive laboratory study. Methods: Nineteen male participants (mean age, 26.3 ± 4.4 years) who had undergone unilateral ACLR within the previous 12 months completed 2 sessions of bilateral passive knee JPS evaluation. JPS testing was conducted in both the flexion (starting angle, 0°) and the extension (starting angle, 90°) directions in the sitting position. The absolute error, constant error, and variable error of the JPS test in both directions were calculated at 2 target angles (30° and 60° of flexion) by using the angle reproduction method for the ipsilateral knee. The standard error of measurement (SEM), smallest real difference (SRD), and intraclass correlation coefficients (ICCs) with 95% Cis were calculated. Results: ICCs were higher for the JPS constant error (operated and nonoperated knee, 0.43-0.86 and 0.32-0.91, respectively) compared with the absolute error (0.18-0.59 and 0.09-0.86, respectively) and the variable error (0.07-0.63 and 0.09-0.73, respectively). The constant error of the 90°-60° extension test showed moderate to excellent reliability for the operated knee (ICC, 0.86 [95% CI, 0.64-0.94]; SEM, 1.63°; SRD, 4.53°), and good to excellent reliability for the nonoperated knee (ICC, 0.91 [95% CI, 0.76-0.96]; SEM, 1.53°; SRD, 4.24°). Conclusion: The test-retest reliability of the passive knee JPS tests after ACLR varied depending on the test angle, direction, and outcome measure (absolute error, constant error, or variable error). The constant error appeared to be a more reliable outcome measure than the absolute error and the variable error, mainly during the 90°-60° extension test. Clinical Relevance: As constant errors have been found reliable during the 90°-60° extension test, investigating these errors-in addition to absolute and variable errors-to reflect bias in passive JPS scores after ACLR is warranted.

Physiotherapists' attitudes and beliefs about self-management as part of their management for low back pain.

BACKGROUND: Perceptually, there is a discrepancy between research evidence and clinical physiotherapy practice for supporting self-management in people with low back pain (LBP). OBJECTIVE: This study aimed to explore physiotherapists' understanding of LBP; ascertain their knowledge of self-management concepts; and explore their attitudes and beliefs about supporting self-management for LBP within present physiotherapy practice in private and hospital settings. DESIGN: Interpretive Description qualitative methodology, involving in-depth data interpretation to clinical practice, was used. METHODS: Semi-structured interviews with physiotherapists throughout New Zealand were conducted via video conferencing. Data was analysed and themes were defined. RESULTS: Seventeen physiotherapists (24-65 years old), with between one and 40+ years of experience, participated. Four main themes were defined: 1) Evolving understanding of LBP, 2) apportioning responsibility, 3) self-management is important, 4) understanding self-management. CONCLUSION: Novel findings from this research demonstrate examples of attitudes and beliefs that determine when and how self-management for people with LBP is implemented. Due to these attitudes and beliefs, physiotherapists may not consistently provide supported self-management for people with LBP. Participants had good understanding of LBP but lacked a contemporary knowledge of the natural history and tended to apportion responsibility for persistent or recurrent episodes to the person with LBP. Physiotherapists should be encouraged to assimilate more contemporary research evidence into their expectations of recovery for LBP. Further education about the role of physiotherapists in supporting self-management, the core components of self-management, including engagement, and reflection upon individual unconscious bias should be encouraged.

The balancing act - Physiotherapists' experiences of managing rugby-related concussion in the community.

BACKGROUND: New Zealand Rugby (NZR) implemented a concussion management pathway (CMP) to improve management at the community level. Physiotherapists play an important role in the CMP. OBJECTIVE: This study explored physiotherapists' experiences in the management of community rugby-related concussion as part of the CMP. METHODS: We adopted a pragmatic, descriptive qualitative approach to explore perceptions of twenty-four physiotherapists involved in the CMP. Thematic analysis was used to analyze data. RESULTS: Four themes represented participants' experiences: 1) 'walking the tight rope between player welfare and performance' described the balancing act between different attitudes and priorities of the various rugby stakeholders; 2) empowering physiotherapists' authority and responsibilities, described the influence of physiotherapists' authority within the team and concussion management responsibilities; 3) multi-directional communication, described the role of communication between multiple stakeholders; and 4) the influence of context, which included the complexity of concussion, concussion knowledge of the physiotherapists and team, resource support for the physiotherapist, and access to a medical doctor. CONCLUSION: Physiotherapists had positive attitudes toward the CMP and are well-positioned to play an active role in the pathway. Priorities of other stakeholders, authority of the physiotherapist and the communication flow influences physiotherapists' ability to optimally manage players with concussion.

'Thinking about pain in a different way': Patient perspectives of a neuroscience-informed physiotherapy programme for rotator cuff-related shoulder pain.

BACKGROUND: Rotator cuff-related shoulder pain (RCRSP) is a common musculoskeletal problem. The multi-factorial contributors to persistent pain are often overlooked during treatment. Pain neuroscience education (PNE) contributes to a holistic approach for patients with persistent pain but has not yet been researched for patients with RCRSP. OBJECTIVE: To explore the perspectives and experiences of participants with RCRSP who had completed a programme of PNE-informed pragmatic physiotherapy. DESIGN: A qualitative study using semi-structured interviews. METHODS: We included a sub-group of five males and five females, aged 46-75 years, with persistent RCRSP of at least three months. They had undertaken a three-month pragmatic physiotherapy integrated with PNE. Individual semi-structured interviews were recorded, transcribed verbatim, and analysed using the General Inductive Approach. RESULTS: Four themes emanated from the interviews. The first two themes were named 'Patient Beliefs' and overall 'Rapport and Relationship'. Another theme, 'Perspective and Understanding of the Resources', indicated diverse uptake of the resource information. The participants reported developing self-management skills, active coping strategies and a reduction in fear of pain described by the theme: 'Empowerment: My Shoulder into the Future'. CONCLUSIONS: Participants experienced a change in their beliefs, which were enhanced by an individualised delivery and a strong therapeutic relationship through the course of the physiotherapy care. The participants appeared to value when the physiotherapist listened to and understood their beliefs. This required a shift in the patient-therapist relationship from the physiotherapist being the 'expert' to facilitating the patient's ability to take control of their shoulder health.

A critical appraisal of web-based information on shoulder pain comparing biomedical vs. psychosocial information.

BACKGROUND: Websites have become a primary way for patients to access health-related information, which allows patients to not only understand their condition better but also to engage in better decision making with their health care provider. However, this can be a double-edged sword, as information patients access may not be of high quality, easily readable, or could be biased based on website authorship. This study examines the readability and content quality of common websites about shoulder pain, with a specific focus on biomedical vs. psychosocial information. METHODS: The Flesch reading-ease score (FRES) and Flesch-Kincaid grade level (FKGL) instruments were used to assess website readability. Health on the net code of conduct (HONcode) certification and the DISCERN tool were used to evaluate the reliability and quality of information. Lastly, shoulder-specific content quality and focus was gauged using a Shoulder-specific Website Appraisal Tool (SWAT) created for this study. A systematic search protocol was used to identify popular shoulder injury websites. The websites were identified using 5 search terms (shoulder pain, shoulder muscle pain, shoulder impingement, shoulder rotator cuff pain, and shoulder pain diagnosis) across 5 English-speaking regions (United States, Canada, United Kingdom, Australia, and New Zealand) using the Google search engine. The top 10 websites for each term and region combination were included and combined, yielding 41 original websites for appraisal; several (6) websites were omitted as duplicates, behind paywalls, or nontext (video) for a total of 35 websites appraised. RESULTS: On average, the FRES shoulder pain websites readability was 55.37, which is categorized as "fairly difficult" to read, and a seventh- or eighth-grade reading level based on the FKGL. For trustworthiness and bias, 57% (20 of 35) of the websites were HONcode certified. The quality of health care information using the DISCERN score averaged 50.92%. Examining shoulder-specific content quality, the average SWAT score was 10.54 out of 14 possible points, with only 1 website reporting information on psychosocial aspects of shoulder pain. CONCLUSIONS: This study suggests that shoulder pain websites present information that is at too high of a reading level for public consumption, has a strong bias toward biomedical causes of shoulder pain, and would benefit from implementation of website screening tools to improve evidence-based content.

Can a knee sleeve influence ground reaction forces and knee joint power during a step-down hop in participants following anterior cruciate ligament reconstruction? A secondary analysis.

PURPOSE: Elastic knee sleeves are often worn following anterior cruciate ligament (ACL) reconstruction. The study aimed to define immediate and 6-week effects of wearing a knee sleeve on ground reaction forces (GRF) and knee joint power during a step-down hop task. METHODS: Using a cross-over design, we estimated GRF and knee kinematics and kinetics during a step-down hop for 30 participants following ACL reconstruction (median 16 months post-surgery) with and without wearing a knee sleeve. In a subsequent randomised clinical trial, participants in the 'Sleeve Group' (n = 9) wore the sleeve for 6 weeks at least 1 hour daily, while a 'Control Group' (n = 9) did not wear the sleeve. We compared the following outcomes using statistical parametric mapping (SPM): (1) GRF and knee joint power trajectories between three conditions at baseline (uninjured side, unsleeved injured and sleeved injured side); (2) GRF and knee joint power trajectories within-participant changes from baseline to follow-up between groups. We also compared discrete peak GRFs and power, rate of (vertical) force development, and mean knee joint power in the first 5% of stance phase. RESULTS: SPM showed no differences for GRF for the (unsleeved) injured compared to the uninjured sides; when wearing the sleeve, injured side mean power in the first 5% of stance increased significantly from a concentric to an eccentric power. Discrete variables showed lower peak anterior (propulsive) GRF, mean power in the first 5% of stance, peak eccentric and concentric power for the injured compared to the uninjured sides. After six weeks, a directional change for vertical GRF differed showed slightly decreased forces for the Control Group and increased forces for the Sleeve Group. CONCLUSION: Wearing a knee sleeve on the anterior cruciate ligament injured knee improved knee power during the first 5% of stance during the step-down hop. No consistent changes were observed for ground reaction forces for SPM and discrete variable analyses. Wearing the knee sleeve at least one hour daily for 6-weeks lead to a directional change of increased vertical GRF for the Sleeve Group at follow-up. TRIAL REGISTRATION: The trial was prospectively registered with the Australia New Zealand Clinical Trials Registry No: ACTRN12618001083280, 28/06/2018. https: //anzctr.org.au/Trial/Registration/TrialReview.aspx?id=375347&isClinicalTrial=False.

Co-Design of an Educational Resource with Female Partners of Male Stroke Survivors to Support Physical Activity Participation.

Many male stroke survivors find it challenging to meet the recommended physical activity (PA) guidelines for health benefits. The spouse/partner is an important source of self-management for stroke survivor PA participation; however, they feel unsupported by health professionals. This study aimed to co-design an educational resource prototype to guide and empower female partners in supporting male stroke survivors' participation in PA. We used a participatory action research (PAR) methodology. Thirteen support persons of male stroke survivors from Canterbury, New Zealand participated in four PAR cycles. The data were collected using individual interviews and focus groups and analyzed inductively using the general inductive approach. Three themes were reflected in the data and informed the prototype content: (1) managing an unwanted and challenging new life, (2) inconsistent access to meaningful information, and (3) considerations for successful stroke survivor PA participation. If partners are to be an essential source in supporting stroke survivors' self-management of PA, they require resources that are meaningful and credible to enhance their confidence and self-efficacy. Further research is needed to explore the acceptability and usability of the educational resource with a wider audience and evaluate the co-design process. An inclusive and collaborative approach where support persons were valued for their expertise was essential in co-designing a meaningful resource intended to support stroke survivors and support persons' self-management of their PA.

Time to expand the circle of care - General practitioners' experiences of managing concussion in the community.

New Zealand Rugby (NZR) implemented a concussion management pathway (CMP), aimed at improving management at community level. General Practitioners (GPs) played a large role in the design of this process. The objective of this study was to explore GPs' perceptions of barriers and facilitators of the CMP and rugby-related concussion management in the community. A descriptive qualitative approach using interviews and focus groups was employed. Four themes were derived: i) GPs' existing knowledge and confidence around concussion management; ii) Operational resources: time, remuneration and pathway guidance; iii) Standardising concussion care and iv) Expanding the circle of care - the need for multi-disciplinary healthcare team. These themes described how GP's concussion knowledge, and the efficiency and availability of operational resources affected their experience and ability to fulfil their tasks within the CMP. GPs found NZR's CMP especially valuable, as it provided guidance and structure. Expanding the role of other healthcare providers was seen as critical to reduce the burden on GPs, while also delivering a more holistic experience to improve clinical outcomes. Addressing the identified barriers and expanding the network of care will help to improve the ongoing development of NZR's CMP, while supporting continued engagement with all stakeholders.

Influence of the frame of reference on head acceleration events recorded by instrumented mouthguards in community rugby players.

Objectives: To highlight the need for standardisation in the communication of head impact telemetry from instrumented mouthguards (iMG). The purpose of this study is to examine how the frame of reference for reporting head acceleration events (HAE) may affect the interpretation of head impacts recorded from iMGs in community rugby players. Methods: An analytical investigation of 825 video verified HAEs recorded from male community players during 5 rugby match exposures. HAEs were captured with an iMG, known to be reliable and valid for this purpose. The linear and angular head acceleration at the centre of mass (head_CG) was calculated from filtered iMG accelerometer and gyroscope data, and the location of impact was estimated. The iMG and head_CG data were examined for systematic bias, geometric differences and the degree of concordance. Finally, mixed model analyses were fitted to assess the differences in peak resultant acceleration (PLA) by impact locations and directions of head motion while controlling for intra-athlete correlations. Results: The degree of concordance between the iMG versus head_CG measures varied by impact location. The mixed model confirmed differences in the PLA by location (F(8,819) = 16.55, p<0.001) and by direction of head motion (F(5,417) = 7.78, p<0.001). Conclusion: The head acceleration reported at the iMG is not proportional to measurements that have been transformed to the head_CG. Depending on the impact location and direction of head motion, the acceleration measured at the iMG may overestimate, underestimate or miss entirely the PLA with respect to the head_CG. We recommend standardising the reporting of iMG data within the head_CG frame of reference.

Association between changes in pain or function scores and changes in scapular rotations in patients with subacromial shoulder pain: a prospective cohort study.

BACKGROUND: Scapular dyskinesis is reported as one of the potential factors contributing to the presentation of pain in subacromial shoulder pain. In clinical practice, the evaluation and control of scapular dyskinesis is considered important for managing the subacromial shoulder pain. The aim is to determine the association between changes in pain or function and changes in scapular rotations in participants with subacromial shoulder pain. METHOD: Pain, function and scapular rotations were measured in 25 participants with subacromial shoulder pain at baseline and after 8 weeks. Pain was measured with Numeric Pain Rating Scale (NPRS) and function was measured with Patient Specific Functional Scale (PSFS). Scapular rotations were measured with a scapular locator at 60°, 90° and 120° of scapular arm elevation. Spearman rank correlations (rs) were used to assess the association between variables. FINDINGS: No association was observed between changes in pain or function scores with changes in scapular upward/downward rotations (rs = 0.03 to 0.27 for pain and - 0.13 to 0.23 for function) and scapular anterior/posterior tilt (rs = - 0.01 to 0.23 for pain and - 0.13 to 0.08 for function) of arm at 60°, 90° and 120° elevation. Data associated with scapular internal/external rotation was not reported due to low reliability. CONCLUSION: These findings reject associations between changes in pain or function scores and scapular rotations. Future observational study is warranted using a multifactorial approach to understand potential factors that contribute to the presentation of subacromial shoulder pain.

Immediate and six-week effects of wearing a knee sleeve following anterior cruciate ligament reconstruction on knee kinematics and kinetics: a cross-over laboratory and randomised clinical trial.

BACKGROUND: Elastic knee sleeves are often worn following anterior cruciate ligament reconstruction (ACLR) but their effects on movement patterns are unclear. AIM: To determine the immediate and six-week effects of wearing a knee sleeve on biomechanics of the knee during a step-down hop task. METHODS: Using a cross-over design, we estimated sagittal plane knee kinematics and kinetics and stance duration during a step-down hop for 31 participants (age 26.0 [SD 6.6] years, 15 women) after ACLR (median 16 months post-surgery) with and without wearing a knee sleeve. In a subsequent randomised clinical trial, participants in the 'Sleeve Group' (n = 9) then wore the sleeve for 6 weeks at least 1 h daily, while a 'Control Group' (n = 9) did not wear the sleeve. We used statistical parametric mapping to compare (1) knee flexion/extension angle and external flexion/extension moment trajectories between three conditions at baseline (uninjured side, unsleeved injured side and sleeved injured side); (2) within-participant changes for knee flexion angles and external flexion/extension moment trajectories from baseline to follow-up between groups. We compared discrete flexion angles and moments, and stance duration between conditions and between groups. RESULTS: Without sleeves, knee flexion was lower for the injured than the uninjured sides during mid-stance phase. When wearing the sleeve on the injured side, knee flexion increased during the loading phase of the stance phase. Discrete initial and peak knee flexion angles increased by (mean difference, 95% CIs) 2.7° (1.3, 4.1) and 3.0° (1.2, 4.9), respectively, when wearing the knee sleeve. Knee external flexion moments for the unsleeved injured sides were lower than the uninjured sides for 80% of stance phase, with no change when sleeved. The groups differenced for within-group changes in knee flexion trajectories at follow-up. Knee flexion angles increased for the Control group only. Stance duration decreased by 22% for the Sleeve group from baseline to follow-up (-89 ms; -153, -24) but not for the Controls. CONCLUSIONS: Application of knee sleeves following ACLR is associated with improved knee flexion angles during hop landing training. Longer term (daily) knee sleeve application may help improve hop stance duration, potentially indicating improved hop performance. TRIAL REGISTRATION: The trial was prospectively registered with the Australia New Zealand Clinical Trials Registry No: ACTRN12618001083280, 28/06/2018. ANZCTR.

Tailored exercise and manual therapy versus standardised exercise for patients with shoulder subacromial pain: a feasibility randomised controlled trial (the Otago MASTER trial).

OBJECTIVES: The aim of this study was to assess whether it was feasible to conduct a full trial comparing a tailored versus a standardised exercise programme for patients with shoulder subacromial pain. DESIGN: Two-arm, patient-blinded and assessor-blinded, randomised controlled feasibility trial. METHODS: Twenty-eight participants with shoulder subacromial pain were randomly allocated into one of two intervention groups-tailored or standardised exercise. Participants in the tailored exercise programme received exercises and manual therapy tailored to their scapular and shoulder movement impairments. Participants in the standardised exercise programme received progressive strengthening exercise. The primary outcome measures were (1) the participant recruitment rate; (2) the proportion of participants enrolled from the total number screened; (3) drop-out rates; and (4) adherence to the rehabilitation programme. Other outcome measures were: (5) pain levels; (6) Patient-Specific Functional Scale; (7) the Shoulder Pain and Disability Index; and (8) pain self-efficacy. We compared changes in pain and disability scores between groups using a repeated mixed-model analysis of variance. Since this is a feasibility study, we did not adjust alpha for multiple comparisons, and considered 75% CI as the probability threshold at 3-month follow-up. Health-related quality of life was assessed using the Short-Form 12 and quality-adjusted life years (QALYs) were estimated. RESULTS: The recruitment rate was 3 participants per month, the proportion of participants enrolled was 23%, the drop-out rate was 14% and the overall adherence to the rehabilitation programme was 85%. No between-group differences were found for most outcome measures. Adverse events (n=2, only in the tailored group) were minor in nature and included skin injury or pain following taping. CONCLUSIONS: Our feasibility trial showed that additional strategies are required for improving recruitment, enrolment and minimising drop-out of participants into the trial and making it feasible to conduct a full trial.

Impact of fatigue at the shoulder on the contralateral upper limb kinematics and performance.

BACKGROUND: Altered movement patterns have been proposed as an etiological factor for the development of musculoskeletal pain. Fatigue influences upper limb kinematics and movement performance which could extend to the contralateral limb and potentially increasing risk of injury. The aim of this study was to investigate the impact of fatigue at the dominant arm on the contralateral upper limb movement. METHODS: Forty participants were randomly assigned to one of two groups: Control or Fatigue Group. All participants completed a reaching task at the baseline and post-experimental phase, during which they reached four targets with their non-dominant arm in a virtual reality environment. Following the baseline phase, the Fatigue Group completed a shoulder fatigue protocol with their dominant arm only, while the Control Group took a 10-minute break. Thereafter, the reaching task was repeated. Upper limb and trunk kinematics (joint angles and excursions), spatiotemporal (speed and accuracy) and surface electromyographic (sEMG) activity (sEMG signal mean epoch amplitude and median frequency of the EMG power spectrum) were collected. Two-way repeated-measures ANOVA were performed to determine the effects of Time, Group and of the interaction between these factors. RESULTS: There was a significant Time x Group interaction for sternoclavicular elevation range of motion (p = 0.040), movement speed (p = 0.043) and accuracy (p = 0.033). The Fatigue group showed higher contralateral sternoclavicular elevation and increased movement error while experiencing fatigue in the dominant arm. Moreover, the Control group increased their speed during the Post-experimental phase compared to baseline (p = 0.043), while the Fatigue group did not show any speed improvement. There was no EMG sign of fatigue in any of the muscles evaluated. CONCLUSION: This study showed that fatigue at the dominant shoulder impacts movement at the contralateral upper limb. Such changes may be a risk factor for the development of shoulder pain in both the fatigued and non-fatigued limbs.

Effectiveness of Physical Activity and Exercise on Ambulatory Blood Pressure in Adults with Resistant Hypertension: A Systematic Review and Meta-Analysis.

INTRODUCTION: Resistant hypertension (RHT) is a phenotype of hypertension that is challenging to manage by medications alone. While high grade evidence supports physical activity (PA) and exercise to reduce blood pressure (BP) in hypertension, it is unclear whether these are also effective for RHT. AIMS: To determine the quality of evidence for the effectiveness of PA and exercise and the change of magnitude of 24-hour ambulatory BP (24hABP) in adults with RHT. METHODS: Scopus, MEDLINE, CINHAL, Web of Science, Embase and SPORTDiscus databases were searched. Cochrane risk of bias tools, Review Manager and Grading of the Recommendation Assessment, Development and Evaluation were used to assess the methodological quality, the clinical heterogeneity and quality of the evidence. RESULTS: Four studies comprising 178 individuals in total were included. A meta-analysis with random effects showed decreased 24hABP. The experimental group demonstrated grater mean differences for 24hABP following the PA and exercise programmes (systolic - 9.88 mmHg, 95% CI: - 17.62, - 2.14, I2 = 72%, p = 0.01; diastolic - 6.24 mmHg, 95% CI: - 12.65, 0.17, I2 = 93%,p = 0.06); and aerobic exercise (systolic - 12.06 mmHg, 95% CI: - 21.14, - 2.96, I2 = 77%, p = 0.009, diastolic - 8.19 mmHg, 95% CI: - 14.83, - 1.55, I2 = 92% ,p = 0.02). In the included studies, indirectness and publication bias were 'moderate' while inconsistency and imprecision were rated as 'low'. Thus, the overall quality of the evidence was considered to be 'low'. CONCLUSIONS: Low certainty evidence suggests that PA and aerobic exercise added to usual care may be more effective in 24hABP reduction in RHT than usual care alone.

Sport concussion assessment in New Zealand high school rugby players: a collaborative approach to the challenges faced in primary care.

PRIMARY OBJECTIVE: To describe the collaborative development of a New Zealand Rugby Concussion Assessment (NZRCA) for primary care and to provide normative baseline data from a representative group of high school rugby players. METHODS: This study, conducted over the 2018 and 2019 community rugby season where players were baseline tested during the pre- or start of season period. RESULTS: Data were collected from 1428 players (males n = 1121, females n = 307) with a mean age of 15.9 ± 1.4 years. The mean ± SD symptom severity score was 11.3 ± 8.6, the mean number of endorsed symptoms was 8.5 ± 5.3 and the percentage feeling "normal" was 80.2 ± 15.3%. Only 5.3% of players reported no symptoms at baseline. The most common reported were: 'distracted easily' (72.5%), 'forgetful' (68.5%), and 'often tired' (62.6%). None of the participants achieved a perfect score for the SAC50. The majority of participants (89.7%) passed the tandem gait test with a time of 12.2 ± 1.7 seconds. Age, gender, and ethnicity were associated with NZRCA performance; albeit weakly. CONCLUSION: This study provides normative reference values for high-school rugby players. These data will aid healthcare providers in their identification of suspected concussion in the absence of individualized baselines.
