Maximising neuromuscular performance in people with pain and injury: moving beyond reps and sets to understand the challenges and embrace the complexity.

Rehabilitative practice is often criticised for being non-individualised, monotonous and not well aligned with foundational principles that drive continued physiological adaptation(s). However, our understanding of neuromuscular physiology is rapidly increasing and the way we programme rehabilitation is improving. This viewpoint highlights some of the potential considerations around why the adaptations achieved during rehabilitation programmes may be suboptimal. We provide basic, clinician-focused discussion about potential confounding physiological factors, and put forward several exercise-based programming recommendations and novel approaches to consider in contemporary rehabilitative practice. Specifically, we outline several potential mechanisms contributing to poor muscle activation and function that might be present following musculoskeletal injury. However, clinicians require strategies capable of attenuating these impairments to restore proper function. Therefore, we also provide an overview of recommended strength and conditioning guidelines, and novel strategies (such as external pacing and electrical stimulation techniques) that clinicians can consider to potentially improve the efficacy of musculoskeletal rehabilitation.

Are we asking the right questions to people with Achilles tendinopathy? The best questions to distinguish mild versus severe disability to improve your clinical management.

OBJECTIVE: Determine the capacity of individual items on the Tendinopathy Severity Assessment - Achilles (TENDINS-A), Foot and Ankle Outcome Score (FAOS), and Victorian Institute of Sports Assessment - Achilles (VISA-A) to differentiate patients with mild and severe tendon-related disability in order to provide clinicians the best questions when they are consulting patients with Achilles tendinopathy. DESIGN: Cross-sectional. PARTICIPANTS: Seventy participants with Achilles tendinopathy (61.4% mid-portion only, 31.4% insertional only, 7.2% both). OUTCOME MEASURES: The discrimination index was determined for each TENDINS-A, FAOS, and VISA-A item to determine if items could discriminate between mild and severe disability. A Guttman analysis for polytomous items was conducted. RESULTS: All 62 tems from the TENDINS-A, FAOS, and VISA-A were ranked with the best items relating to pain with physical tendon loading, time for pain to settle following aggravating activities and time for the tendon to 'warm-up' following inactivity. CONCLUSIONS: Pain with loading the Achilles tendon, time for pain to settle following aggravating activity, as well as time taken for the tendon symptoms to subside after prolonged sitting or sleeping are the best questions indicative of the severity of disability in patients with Achilles tendinopathy. These questions can assist clinicians with assessing baseline severity and monitoring treatment response.

TENDINopathy Severity assessment-Achilles (TENDINS-A): evaluation of reliability and validity in accordance with COSMIN recommendations.

OBJECTIVE: To evaluate the construct validity (structural validity and hypothesis testing), reliability (test-retest reliability, measurement error and internal consistency) and minimal important change (MIC) of the 13-item TENDINopathy Severity assessment-Achilles (TENDINS-A). METHODS: Participants with Achilles pain completed an online survey including: demographics, TENDINS-A, Foot and Ankle Outcome Score (FAOS) and Victorian Institute of Sport Assessment-Achilles (VISA-A). Exploratory factor analysis (EFA) assessed dimensionality. Confirmatory factor analysis (CFA) assessed structural validity (root mean square error of approximation (RMSEA); Comparative Fit Index (CFI); Tucker-Lewis Index (TLI); standardised root measure square (SRMS)). Correlations between TENDINS-A and the FAOS or VISA-A assessed hypothesis testing. Intraclass correlation (ICC) assessed test-retest reliability. Cronbach's alpha assessed internal consistency. SE of the measurement (SEM) assessed measurement error. A distribution-based approach assessed MIC. RESULTS: 79 participants (51% female) with a mean (SD) age=42.6 (13.0) years, height=175.0 (11.7) cm and body mass=82.0 (19.1) kg were included. EFA identified three meaningful factors, proposed as pain, symptoms and function. The best model identified using CFA for TENDINS-A had structural validity (RMSEA=0.101, CFI=0.959, TLI=0.947, SRMS=0.068), which included three factors (pain, symptoms and function), but excluded three items from the original TENDINS-A. TENDINS-A exhibited moderate positive correlation with FAOS (r=0.598, p<0.001) and a moderate negative correlation with VISA-A (r=-0.639, p<0.001). Reliability of the TENDINS-A was excellent (ICC=0.930; Cronbach's α=0.808; SEM=6.54 units), with an MIC of 12 units. CONCLUSIONS: Our evaluation of the revised 10-item TENDINS-A determined it has construct validity and excellent reliability, compared with the VISA-A and FAOS which lack content and construct validity. The TENDINS-A is recommended as the preferred patient-reported outcome measure to assess disability in people with Achilles tendinopathy.

Where is Your Pain? Achilles Tendinopathy Pain Location on Loading Is Different to Palpation, Imaging and Recall Location.

OBJECTIVE: To describe and compare pain maps reported during Achilles tendon loading exercises with recall pain location, in people with pain on palpation in their Achilles tendon and tendon pathology on imaging. DESIGN: Cross-sectional analysis of baseline RCT. METHOD: Participants were recruited from a larger Achilles tendinopathy clinical trial. Inclusion criteria were at least 2-month self-reported history of Achilles tendinopathy, midtendon palpation pain, and pathology on ultrasound tissue characterization. Participants were asked to identify their Achilles tendon pain location on a pain map with 8 prespecified locations while at rest prior to loading (recall pain), and subsequently during tendon loading exercises (loading pain). Participants could select multiple locations or select "other" if the locations did not represent their pain. RESULTS: Ninety-three participants were included (93% of participants from a clinical trial). The locations of pain on loading were diverse; all 8 pain locations (and an "other" option) were represented within this sample. Twenty-five percent of participants did not report pain with loading (n = 23 of 93). Of the 70 participants with loading pain, recall pain location differed to loading pain location in 40% (n = 28 of 70) of the participants. CONCLUSION: Palpation pain location, recall pain location, or location of pathology on imaging were not valid proxies for load-related pain in the Achilles tendon. How different pain locations respond to treatment is unknown. Some pathologies (eg, plantaris) have clear pain locations (eg, medial tendon), and assessing pain location may assist differential diagnosis. J Orthop Sports Phys Ther 2024;54(1):1-9.

Does lower-limb osteoarthritis alter motor cortex descending drive and voluntary activation? A systematic review and meta-analysis.

Purpose: The aim of the study was to quantify motor cortex descending drive and voluntary activation (VA) in people with lower-limb OA compared to controls. Methods: A systematic review and meta-analysis according to the PRISMA guidelines was carried out. Seven databases were searched until 30 December 2022. Studies assessing VA or responses to transcranial magnetic stimulation (TMS; i.e. motor evoked potential, intracortical facilitation, motor threshold, short-interval intracortical inhibition, and silent period) were included. Study quality was assessed using Joanna Briggs Institute criteria and evidence certainty using GRADE. The meta-analysis was performed using RevMan inverse variance, mixed-effect models. Results: Eighteen studies were included, all deemed low-quality. Quadriceps VA was impaired with knee OA compared to healthy controls (standardised mean difference (SMD) = 0.84, 95% CI = -1.12-0.56, low certainty). VA of the more symptomatic limb was impaired (SMD = 0.42, 95% CI = -0.75-0.09, moderate certainty) compared to the other limb in people with hip/knee OA. As only two studies assessed responses to TMS, very low-certainty evidence demonstrated no significant difference between knee OA and healthy controls for motor evoked potential, intracortical facilitation, resting motor threshold or short-interval intracortical inhibition. Conclusions: Low-certainty evidence suggests people with knee OA have substantial impairments in VA of their quadriceps muscle when compared to healthy controls. With moderate certainty we conclude that people with hip and knee OA had larger impairments in VA of the quadriceps in their more painful limb compared to their non-affected/other limb.

Epidemiology of musculoskeletal injury in military recruits: a systematic review and meta-analysis.

BACKGROUND: Injuries are a common occurrence in military recruit training, however due to differences in the capture of training exposure, injury incidence rates are rarely reported. Our aim was to determine the musculoskeletal injury epidemiology of military recruits, including a standardised injury incidence rate. METHODS: Epidemiological systematic review following the PRISMA 2020 guidelines. Five online databases were searched from database inception to 5th May 2021. Prospective and retrospective studies that reported data on musculoskeletal injuries sustained by military recruits after the year 2000 were included. We reported on the frequency, prevalence and injury incidence rate. Incidence rate per 1000 training days (Exact 95% CI) was calculated using meta-analysis to allow comparisons between studies. Observed heterogeneity (e.g., training duration) precluded pooling of results across countries. The Joanna Briggs Institute Quality Assessment Checklist for Prevalence Studies assessed study quality. RESULTS: This review identified 41 studies comprising 451,782 recruits. Most studies (n = 26; 63%) reported the number of injured recruits, and the majority of studies (n = 27; 66%) reported the number of injuries to recruits. The prevalence of recruits with medical attention injuries or time-loss injuries was 22.8% and 31.4%, respectively. Meta-analysis revealed the injury incidence rate for recruits with a medical attention injury may be as high as 19.52 injuries per 1000 training days; and time-loss injury may be as high as 3.97 injuries per 1000 training days. Longer recruit training programs were associated with a reduced injury incidence rate (p = 0.003). The overall certainty of the evidence was low per a modified GRADE approach. CONCLUSION: This systematic review with meta-analysis highlights a high musculoskeletal injury prevalence and injury incidence rate within military recruits undergoing basic training with minimal improvement observed over the past 20 years. Longer training program, which may decrease the degree of overload experienced by recruit, may reduce injury incidence rates. Unfortunately, reporting standards and reporting consistency remain a barrier to generalisability. TRIAL REGISTRATION: PROSPERO (Registration number: CRD42021251080).

Quantifying Fear Avoidance Behaviors in People With Concussion: A COSMIN-Informed Systematic Review.

OBJECTIVE: The validity of existing fear avoidance behavior patient-reported outcome measures (PROMs) for concussion is unknown. This study aims to (1) identify PROMs that assess fear avoidance behavior in individuals with concussion and (2) assess the measurement properties of these PROMs. DESIGN: A systematic review of outcome measurement instruments using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. LITERATURE SEARCH: We performed a systematic search of 7 databases. STUDY SELECTION CRITERIA: Studies were included if they assessed fear avoidance behavior (eg, kinesiophobia or cogniphobia) in participants with concussion, occurring in all settings (eg, sport, falls, assaults). DATA SYNTHESIS: Methodological quality of the PROMs was assessed using the COSMIN checklist, and the certainty of the evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. RESULTS: We identified 40 studies assessing fear avoidance. Four studies (n = 875 participants, representing 3 PROMs) were eligible for COSMIN assessment. Content validity for all PROMs was insufficient due to extreme risk of bias. The Fear Avoidance Short Form Scale demonstrated the greatest validity: moderate-certainty evidence for sufficient structural validity and internal consistency, and low-certainty evidence for measurement invariance. CONCLUSION: Current PROMs for measuring fear avoidance behaviors in people with concussion have insufficient content validity and should be used with caution in research and clinical practice.

TENDINopathy Severity Assessment - Achilles (TENDINS-A): Development and Content Validity Assessment of a New Patient-Reported Outcome Measure for Achilles Tendinopathy.

OBJECTIVE: To develop a new patient-reported outcome measure (PROM) assessing TENDINopathy Severity of the Achilles (TENDINS-Achilles) and evaluate its content validity. DESIGN: Mixed-methods, modified Delphi. METHODS: We performed 1 round of semistructured one-on-one interview responses with professionals and patients, for initial item generation. This was followed by 1 round of survey responses for professionals and a final round of semistructured one-on-one interviews with patients. The work culminated in a PROM to quantify Achilles tendinopathy severity under the core health domain of disability. Participants identified 3 subdomains contributing to the severity of disability of Achilles tendinopathy: pain, symptoms, and functional capacity. RESULTS: All 8 patient participants invited to participate were enrolled. Forty professional participants (50% women, six different continents) were invited to participate and 30 were enrolled (75% response rate). Therefore, a total of 30 professionals and 8 patients were included within this study. Following 3 rounds of qualitative or quantitative feedback, this study has established the content validity of TENDINS-A (good relevance, comprehensibility, and comprehensiveness) as a new PROM to assess the severity of Achilles tendinopathy, which assesses aspects of pain, symptoms, and functional capacity. CONCLUSION: TENDINS-A has established content validity and is appropriate for use with clinical and research populations. We recommend users interpret TENDINS-A results cautiously, until further testing evaluates the most appropriate scoring scale, reliability, construct validity, criterion validity, and responsiveness of TENDINS-A. Until these psychometric properties are established, we suggest using TENDINS-A alongside existing tools. J Orthop Sports Phys Ther 2023;53(11):1-16.

What is the Prevalence of General Anxiety Disorder and Depression Symptoms in Semi-elite Australian Football Players: A Cross-Sectional Study.

BACKGROUND: The prevalence of anxiety and depression symptoms in semi-elite Australian footballers is unknown. The primary objective of this study was to determine the prevalence of generalised anxiety disorder (GAD) and depressive symptoms in semi-elite Australian Football players. Our secondary objective was to explore the association between demographic and football-specific factors with GAD and depressive symptoms. A cross-sectional epidemiological study including 369 semi-elite Western Australian Football League (WAFL) players from the Men and Women's 2022 season (n = 337 men, 91%) was conducted. Symptoms of depression were measured using the Patient Health Questionnaire-9 scale (PHQ-9) and symptoms of GAD with the GAD-7 scale. RESULTS: Our response rate was 82.9%. Thirteen players had missing data. The prevalence of GAD symptoms was 8.5% in men and 28.6% in women (10% overall). The prevalence of depressive symptoms was 20% in men and 57% in women (23% overall). Being a woman (gender) was associated with a sevenfold increased risk of GAD and/or depression symptoms [odds ratio (OR): 7.33, 95% confidence interval (CI): 3.18-16.92; p < 0.001]. Players of 'Aboriginal or Torres Strait Islander' ethnicity were two times more likely to report GAD and/or depression symptoms in comparison to players of 'Australian' ethnicity (OR: 2.13; 95% CI: 1.01-4.49; p = 0.048). Concussion history was not a significant risk factor for GAD or depression symptoms. CONCLUSION: This study demonstrated that approximately 1 in 10 WAFL players met the diagnostic cut-off criteria for probable GAD, and 1 in 5 for probable depression. The prevalence for depression symptoms in this study were far higher than the national average in the comparative age bracket. WAFL women's players also reported a substantially higher prevalence of GAD and depressive symptoms than men, and should be further investigated as a priority by the WAFL.

Can we really say getting stronger makes your tendon feel better? No current evidence of a relationship between change in Achilles tendinopathy pain or disability and changes in Triceps Surae structure or function when completing rehabilitation: A systematic review.

OBJECTIVES: Determine if improvements in pain and disability in patients with mid-portion Achilles tendinopathy relate to changes in muscle structure and function whilst completing exercise rehabilitation. DESIGN: A systematic review exploring the relationship between changes in pain/disability and muscle structure/function over time, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. METHODS: Six online databases and the grey literature were searched from database inception to 16th December 2022 whereas clinical trial registries were searched from database inception to 11th February 2020. We included clinical studies where participants received exercise rehabilitation (±placebo interventions) for mid-portion Achilles tendinopathy if pain/disability and Triceps Surae structure/function were measured. We calculated Cohen's d (95 % confidence intervals) for changes in muscle structure/function over time for individual studies. Data were not pooled due to heterogeneity. Study quality was assessed using a modified Newcastle-Ottawa Scale. RESULTS: Seventeen studies were included for synthesis. No studies reported the relationship between muscle structure/function and pain/disability changes. Twelve studies reported muscle structure/function outcome measures at baseline and at least one follow-up time-point. Three studies reported improvements in force output after treatment; eight studies demonstrated no change in structure or function; one study did not provide a variation measure, precluding within group change over time calculation. All studies were low quality. CONCLUSIONS: No studies explored the relationship between changes in tendon pain and disability and changes in muscle structure and function. It is unclear whether current exercise-based rehabilitation protocols for mid-portion Achilles tendinopathy improve muscle structure or function.

"I lied a little bit." A qualitative study exploring the perspectives of elite Australian athletes on self-reported data.

OBJECTIVES: Explore the perceptions and experiences of elite Australian athletes' engagement with reporting data in surveillance systems. DESIGN: Qualitative Descriptive. SETTING: Semi-structured interviews conducted using Zoom. PARTICIPANTS: We recruited 13 elite Australian athletes competing at a national or international level for semi-structured interviews. MAIN OUTCOME MEASURES: Audio recordings were transcribed using DeScript, checked for errors and imported into QSR NVIVO. Thematic analysis using QSR NVIVO was used to determine key themes from transcripts. RESULTS: Thematic analysis uncovered four key themes: 'the paradox of reporting', 'data for data's sake', 'eyes on reporting' and 'athlete friendly reporting'. CONCLUSION: Athletes perceived reporting as a burden and the athlete management system presented numerous technological difficulties which led to athletes to backfill data entries and compromise data accuracy. Athletes had little knowledge on how their data was used and managed and often received minimal feedback from staff accessing the data. Athletes were unaware of who has access to their data, which is of concern as sensitive information may be collected and athletes may be underage. As a result, many athletes chose to report dishonest data to avoid their performance being questioned.

Cricket injury in New Zealand: a study of injury insurance claims from 2008 to 2018.

OBJECTIVES: This study aimed to quantify injury claims in organised community cricket in New Zealand over a 10-year period, 1 July, 2008 to June 30, 2018. DESIGN: Retrospective analysis of administrative insurance claims data from the Accident Compensation Corporation (ACC), New Zealand. METHODS: Injury claims relating to cricket in males and females in New Zealand were identified from coded data and relevant text searches of routinely collected claims data. Summary statistics for key variables (age, body part, injury type, and injury factors) are presented together with annual injury claim incidence rates (ICR) calculated using population-based denominators. RESULTS: There were 62,776 claims for cricket injury occurring at a place of recreation/sports. Most claims were in males (91.4%) and those aged 15-19 year old age group. There was an increase in the total number of injury claims over the 10-year period (1.5%, p = 0.04), but the ICR was consistent (males: varying between 258.8-304.8, and females: 22.6-28.3 claims annually per 100,000 population). Soft tissue injury claims were the most common injury type. Lumbosacral claims were most common for bowlers (78%). Lower limb injury claims were the predominant claim from batting (36%) and fielding (42%), with knee injury claims (34%) being the most common lower-limb injury location. CONCLUSIONS: Lumbosacral, shoulder and knee injuries were common amongst all playing positions and worthy of preventative attention. Strategies targeting prevention of these injuries may reduce the ICR within the ACC.

Injury Profiles of Police Recruits Undergoing Basic Physical Training: A Prospective Cohort Study.

Purpose A lack of published epidemiological data among police recruits presents a major challenge when designing appropriate prevention programs to reduce injury burden. We aimed to report the injury epidemiology of Western Australian (WA) Police Force recruits and examine sex and age as injury risk factors. Methods Retrospective analyses were conducted of prospectively collected injury data from WA Police Force recruits between 2018-2021. Injury was defined as 'time-loss' and injury incidence rate per 1000 training days (Poisson exact 95% confidence intervals) was calculated. For each region and type of injury, the incidence, severity, and burden were calculated. The association between age, sex, and injury occurrence were assessed using Cox regression time-to-event analysis. Results A total of 1316 WA Police Force recruits were included, of whom 264 recruits sustained 304 injuries. Injury prevalence was 20.1% and the incidence rate was 2.00 (95%CI 1.78-2.24) injuries per 1000 training days. Lower limb injuries accounted for most of the injury burden. Ligament/ joint injuries had the highest injury tissue/pathology burden. The most common activity injuring recruits was physical training (31.8% of all injuries). Older age (Hazard Ratio = 1.5, 95%CI = 1.2 to 1.9, p = 0.002) and female sex (Hazard Ratio = 1.4, 95%CI = 1.3 to 1.6, p < 0.001) increased risk of injury. Conclusion Prevention programs targeting muscle/tendon and ligament/joint injuries to the lower limb and shoulder should be prioritised to reduce the WA Police Force injury burden. Injury prevention programs should also prioritise recruits who are over 30 years of age or of female sex, given they are a higher risk population.

Evaluation and Utility of the King-Devick With Integrated Eye Tracking as a Diagnostic Tool for Sport-Related Concussion.

Background: Eye-tracking technology for detecting eye movements has been gaining increasing attention as a possible assessment and monitoring tool for sport-related concussion (SRC). Purpose: To determine the diagnostic accuracy of a rapid number-naming task with eye tracking, the King-Devick Eye Tracking (K-D ET) assessment, in identifying SRC. Study Design: Cohort study. Methods: One female and 1 male team of United States collegiate rugby-15 players competing during the 2018 season were recruited. Variables assessed were total saccades, saccade velocity, total fixations, fixation duration, fixation polyarea, and test duration. A generalized estimating equation was used to examine group (concussion vs nonconcussion), time (baseline vs postinjury/postseason), and sex-based differences for each outcome measure. In addition, the different components of diagnostic accuracy of the K-D ET were calculated. Results: Baseline K-D ET assessment for 49 participants (25 male, 24 female) were assessed at the beginning of the season, with 28 participants who did not sustain a head injury during the season completing the postseason assessments and 6 participants completing a postinjury (suspected concussion) assessment. Significant differences were observed between concussed and nonconcussed groups for total saccades (P = .024), fixation duration (P = .007), and fixation polyarea (P = .030), with differences from baseline to follow-up observed for saccade velocity (P = .018) in both groups. Sex-based differences were noted for total fixations (P = .041), fixation polyarea (P = .036), and completion time (P = .035). No significant Group × Time interactions were noted. The K-D ET test duration indicated high specificity (0.86) but not high sensitivity (0.40). No other variables reported high sensitivity or specificity. Conclusion: Other than completion time of the K-D ET test, no K-D ET oculomotor parameter was highly sensitive or specific in the diagnosis of concussion in this study.

Cardiorespiratory fitness is a risk factor for lower-limb and back injury in law enforcement officers commencing their basic training: a prospective cohort study.

We aimed to report the epidemiology of lower-limb and lumbosacral injuries in Police Force recruits. We performed a cohort study of Police Force recruits undergoing a six-month training program with prospective injury data collected between 2018 and 2021. Cardiorespiratory fitness was quantified by the beep-test and police-specific-functional-capacity was quantified using a specifically designed physical performance evaluation (PPE) tool. Injury frequency and prevalence were reported. Fifteen percent (n = 180) of study Police Force recruits (n = 1,181) sustained a lower-limb or lumbosacral injury. The six-month training program significantly improved cardiorespiratory fitness (p < 0.001) and functional capacity (p < 0.001). Increased cardiorespiratory fitness at baseline decreased injury risk (OR = 0.8, 95%CI: 0.66-0.97, p = 0.019). Injury rates decreased over time and females were injured significantly earlier than males (HR = 0.70, 95%CI: 0.52 to 0.95, p = 0.021). Interventions that can pre-condition Police Force recruits prior to the commencement of their basic physical training may reduce the number of lower-limb and lumbosacral injuries.

Association of developmental coordination disorder and low motor competence with impaired bone health: A systematic review.

AIMS: Individuals with developmental coordination disorder (DCD) and low motor competence (LMC) may be at increased risk of low bone health due to their lifetime physical activity patterns. Impaired bone health increases an individual's risk of osteoporosis and fracture; therefore, it is necessary to determine whether a bone health detriment is present in this group. Accordingly, this systematic review explores the association between DCD/LMC and bone health. METHODS AND PROCEDURES: Studies were included with assessment of bone health in a DCD/LMC population. Study bias was assessed using the JBI critical appraisal checklist. Due to heterogeneity, meta-analysis was not possible and narrative synthesis was performed with effect size and direction assessed via harvest plots. OUTCOMES AND RESULTS: A total of 16 (15 paediatric/adolescent) studies were included. Deficits in bone measures were reported for the DCD/LMC group and were more frequent in weight-bearing sites. Critical appraisal indicated very low confidence in the results, with issues relating to indirectness and imprecision relating to comorbidities. CONCLUSIONS AND IMPLICATIONS: Individuals with DCD or LMC are at increased risk of bone health deficits. Bone impairment locations indicate insufficient loading via physical activity as a potential cause of bone deficits. Results indicate a potential for earlier osteoporosis onset.

Assessment and monitoring of Achilles tendinopathy in clinical practice: a qualitative descriptive exploration of the barriers clinicians face.

Our primary objective was to explore the barriers preventing clinicians from implementing what they think is ideal practice as it relates to using tools to aid diagnosis and monitor progress in mid-portion Achilles tendinopathy. Our secondary objectives were to describe the assessments employed by clinicians in their own practice to aid with (a) diagnosis and (b) monitoring progress in Achilles tendinopathy and explore the outcome measure domains clinicians believe to be the most and least important when managing patients with Achilles tendinopathy. We employed a qualitative descriptive study design. Thirteen participants (eight female, five male) from across Australia, consisting of two junior physiotherapists, five senior physiotherapists working in private practice, four senior physiotherapists working within elite sports organisations and two sport and exercise medicine doctors, were included and one-on-one interviews were performed. Audio was transcribed then entered into NVivo for coding and analysis. Four main themes were perceived as barriers to implementing ideal practice of assessment and monitoring in people with Achilles tendinopathy: financial constraints, time constraints, access to equipment and patient symptom severity. Assessments related to function, pain on loading, pain over a specified time frame and palpation are commonly used to assist diagnosis. Assessments related to disability, pain on loading, pain over a specified time frame and physical function capacity are used to monitor progress over time. Furthermore, pain on loading and pain over a specified time frame were considered the most important outcome measure domains for assisting diagnosis whereas pain on loading, patient rating of the condition and physical function capacity were the most important outcome measure domains for monitoring progress. A number of barriers exist that prevent clinicians from implementing what they view as ideal assessment and monitoring for Achilles tendinopathy. These barriers should be considered when developing new assessments and in clinical practice recommendations.
