Efficacy of heel lifts for lower limb musculoskeletal conditions: A systematic review.

INTRODUCTION: The objective of this systematic review is to determine the benefits and harms of heel lifts to any comparator for lower limb musculoskeletal conditions. METHODS: Ovid MEDLINE, Ovid AMED, Ovid EMCARE, CINAHL Plus and SPORTDiscus were searched from inception to the end of May 2024. Randomised, quasi-randomised or non-randomised trials comparing heel lifts to any other intervention or no-treatment were eligible for inclusion. Data was extracted for the outcomes of pain, disability/function, participation, participant rating of overall condition, quality of life, composite measures and adverse events. Two authors independently assessed risk of bias and certainty of evidence using the GRADE approach at the primary time point 12 weeks (or next closest). RESULTS: Eight trials (n = 903), investigating mid-portion Achilles tendinopathy, calcaneal apophysitis and plantar heel pain were included. Heel lifts were compared to exercise, ultrasound, cryotherapy orthotics, stretching, footwear, activity modification, felt pads and analgesic medication. No outcome was at low risk of bias and few effects (2 out of 47) were clinically important. Low-certainty evidence (1 trial, n = 199) indicates improved pain relief (55.7 points [95% CI: 50.3-61.1], on a 100 mm visual analogue scale) with custom orthotics compared to heel lifts at 12 weeks for calcaneal apophysitis. Very low-certainty evidence (1 trial, n = 62) indicates improved pain and function with heel lifts over indomethacin (35.5 points [95% CI: 21.1-49.9], Foot Function Index) at 12 months for plantar heel pain. CONCLUSIONS: Few trials have assessed the benefits and harms of heel lifts for lower limb musculoskeletal conditions. Only two outcomes out of 47 showed clinically meaningful between group differences. However, due to very low to low certainty evidence we are unable to be confident in the results and the true effect may be substantially different.

Efficacy of heel lifts for mid-portion Achilles tendinopathy (the LIFT trial): study protocol for a randomised controlled trial.

BACKGROUND: Mid-portion Achilles tendinopathy is a common condition, characterised by localised Achilles tendon load-related pain and dysfunction. Numerous non-surgical treatments have been proposed for the treatment of this condition, but many of these treatments have a poor or non-existent evidence base. Heel lifts have also been advocated as a treatment for Achilles tendinopathy, but the efficacy and mechanism of action of this intervention is unclear. This proposal describes a randomised controlled trial comparing the effectiveness of heel lifts versus sham heel lifts for reducing pain associated with mid-portion Achilles tendinopathy, with an embedded biomechanical analysis. METHODS: One hundred and eight men and women aged 18 to 65 years with mid-portion Achilles tendinopathy (who satisfy the inclusion and exclusion criteria) will be recruited. Participants will be randomised, using the website Sealed Envelope, to either a control group (sham heel lifts) or an experimental group (heel lifts). Both groups will be provided with education regarding acceptable pain levels to ensure all participants receive some form of treatment. The participants will be instructed to use their allocated intervention for at least 8 h every day for 12 weeks. The primary outcome measure will be pain intensity (numerical rating scale) at its worst over the previous week. The secondary outcome measures will be additional measures of Achilles tendon pain and disability, participant-perceived global ratings of change, function, level of physical activity and health-related quality of life. Data will be collected at baseline and the primary endpoint (week 12). Data will be analysed using the intention-to-treat principle. In addition, the acute kinetic and kinematic effects of the interventions will be examined at baseline in a subpopulation of the participants (n = 40) while walking and running using three-dimensional motion analysis. DISCUSSION: The LIFT trial (efficacy of heeL lIfts For mid-portion Achilles Tendinopathy) will be the first randomised trial to compare the efficacy of heel lifts to a sham intervention in reducing pain and disability in people with Achilles tendinopathy. The biomechanical analysis will provide useful insights into the mechanism of action of heel lifts. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry, ACTRN12623000627651 .

Developing an international consensus Reporting guideline for intervention Fidelity in Non-Drug, non-surgical trials: The ReFiND protocol.

BACKGROUND: Inadequate reporting of fidelity to interventions in trials limits the transparency and interpretation of trial findings. Despite this, most trials of non-drug, non-surgical interventions lack comprehensive reporting of fidelity. If fidelity is poorly reported, it is unclear which intervention components were tested or implemented within the trial, which also hinders research reproducibility. This protocol describes the development process of a reporting guideline for fidelity of non-drug, non-surgical interventions (ReFiND) in the context of trials. METHODS: The ReFiND guideline will be developed in six stages. Stage one: a guideline development group has been formed to oversee the guideline methodology. Stage two: a scoping review will be conducted to identify and summarize existing guidance documents on the fidelity of non-drug, non-surgical interventions. Stage three: a Delphi study will be conducted to reach consensus on reporting items. Stage four: a consensus meeting will be held to consolidate the reporting items and discuss the wording and structure of the guideline. Stage five: a guidance statement, an elaboration and explanation document, and a reporting checklist will be developed. Stage six: different strategies will be used to disseminate and implement the ReFiND guideline. DISCUSSION: The ReFiND guideline will provide a set of items developed through international consensus to improve the reporting of intervention fidelity in trials of non-drug, non-surgical interventions. This reporting guideline will enhance transparency and reproducibility in future non-drug, non-surgical intervention research.

Sensitivity to change and responsiveness of provocative load tests among athletes with patellar tendinopathy.

BACKGROUND: Pain provocation tests are recommended for assessing pain severity and as an outcome measure for individuals with patellar tendinopathy. OBJECTIVE: To evaluate floor and ceiling effects, sensitivity to change, and responsiveness cut-offs of two provocative load tests among athletes with patellar tendinopathy. METHODS: Athletes (N = 41) performed six repetitions for the single leg decline squat (SLDS) and resisted knee extension (KE) at baseline and 12 weeks. Participants rated their pain during each test on a visual analog scale (VAS). Sensitivity to change was assessed by calculating effect size (ES) and the standardized response mean (SRM). The responsiveness cut-offs were assessed using a combination of anchor and distribution- based methods to determine the minimal clinically important difference (MCID) for each test. RESULTS: A floor or ceiling effect was observed in only a small number of participants for both tests except for KE, for which approximately one third of participants had a floor effect at week 12. There was higher sensitivity to change for SLDS (ES: 1.93/SRM: 1.43) compared with KE (ES:0.96/SRM: 1.09). The MCID corresponded to a decrease of 1.6 points for SLDS and 1.0 for KE, while the distribution-based method estimated 1.2 points for SLDS and 1.1 for KE. CONCLUSION: This study found moderate to high sensitivity to change and established MCID values for the SLDS and KE test in athletes with patellar tendinopathy before and after rehabilitation. Both tests may be useful as pain on loading outcomes as athletes progress with their rehabilitation, but the KE test results in higher floor effects and has lower sensitivity to change.

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.

How therapeutic relationships develop in group-based telehealth and their perceived impact on processes and outcomes of a complex intervention: a qualitative study.

BACKGROUND: Therapeutic relationships are a key domain in healthcare delivery. While well-understood in in-person interventions, how therapeutic relationships develop in more complex contexts is unclear. This study aimed to understand (1) how therapeutic relationships are developed during the telehealth delivery of a group-based, complex intervention and (2) the perceived impact of these relationships on intervention processes, such as intervention delivery and engagement, and patient outcomes, such as patient safety and satisfaction. METHODS: This qualitative study, nested within a randomised controlled trial, used an interpretivist approach to explore the perceptions of 25 participants (18 patients with shoulder pain and 7 clinicians) regarding developing therapeutic relationships in a group-based, complex intervention delivered via telehealth. Semi-structured interviews were conducted within 4 weeks of the telehealth intervention period and then analysed through in-depth, inductive thematic analysis. RESULTS: We identified six themes: (1) 'Patients trust clinicians who demonstrate credibility, promoting the development of therapeutic relationships'; (2) 'Simple features and approaches shape the therapeutic relationship', including small talk, time spent together and social observation; (3) 'A sense of belonging and support fosters connections', facilitated by clinicians providing individualised attention within the group; (4) 'Developing therapeutic relationships can impact the delivery of core intervention components', reflecting challenges clinicians faced; (5) 'Therapeutic relationships can facilitate intervention engagement', through enhanced patient understanding and confidence and (6) 'Therapeutic relationships can contribute to patient safety and satisfaction', with patients feeling more comfortable reporting intervention-related issues. CONCLUSIONS: Therapeutic relationships were developed during group-based telehealth sessions through a set of factors that may require additional skills and effort compared with in-person interactions. While these relationships have a perceived positive impact on intervention engagement and patient outcomes, clinicians need to find a balance between building relationships and delivering the telehealth intervention with fidelity.

Evaluation of Patient-Facing Mobile Apps to Support Physiotherapy Care: Systematic Review.

BACKGROUND: Mobile health interventions delivered through mobile apps are increasingly used in physiotherapy care. This may be because of the potential of apps to facilitate changes in behavior, which is central to the aims of care delivered by physiotherapists. A benefit of using apps is their ability to incorporate behavior change techniques (BCTs) that can optimize the effectiveness of physiotherapeutic interventions. Research continues to suggest that despite their importance, behavior change strategies are often missing in patient management. Evaluating mobile apps that physiotherapists can use to drive behavior change may inform clinical practice and potentially improve patient outcomes. Examining the quality of apps and exploring their key features that can support behavior change and physiotherapy care are important aspects of such an evaluation. OBJECTIVE: The primary aim of this study was to describe the range of mobile apps in app stores that are intended for use by patients to support physiotherapy care. The secondary aims were to assess app quality, BCTs, and their behavior change potential. METHODS: A systematic review of mobile apps in app stores was undertaken. The Apple App Store and Google Play were searched using a 2-step search strategy, using terms relevant to the physiotherapy discipline. Strict inclusion and exclusion criteria were applied: apps had to be intended for use by patients and be self-contained (or stand-alone) without the requirement to be used in conjunction with a partner wearable device or another plugin. Included apps were coded for BCTs using the Behavior Change Technique Taxonomy version 1. App quality was assessed using the Mobile App Rating Scale, and the App Behavior Change Scale was used to assess the app's potential to change behavior. RESULTS: In total, 1240 apps were screened, and 35 were included. Of these 35 apps, 22 (63%) were available on both the Apple App Store and Google Play platforms. In total, 24 (69%) were general in their focus (eg, not condition-specific), with the remaining 11 (31%) being more specific (eg, knee rehabilitation and pelvic floor training). The mean app quality score (Mobile App Rating Scale) was 3.7 (SD 0.4) of 5 (range 2.8-4.5). The mean number of BCTs identified per app was 8.5 (SD 3.6). BCTs most frequently included in the apps were instruction on how to perform a behavior (n=32), action planning (n=30), and self-monitoring of behavior (n=28). The mean behavior change potential score (App Behavior Change Scale) was 8.5 (SD 3.1) of 21 (range 3-15). CONCLUSIONS: Mobile apps available to support patient care received from a physiotherapist are of variable quality. Although they contain some BCTs, the potential for behavior change varied widely across apps. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR2-10.2196/29047.

Determining intracortical, corticospinal and alpha motoneurone excitability in athletes with patellar tendinopathy compared to asymptomatic controls.

BACKGROUND: Lower capacity to generate knee extension maximal voluntary force (MVF) has been observed in individuals affected with patellar tendinopathy (PT) compared to asymptomatic controls. This MVF deficit is hypothesized to emanate from alterations in corticospinal excitability (CSE). The modulation of CSE is intricately linked to the excitability levels at multiple sites, encompassing neurones within the corticospinal tract (CST), intracortical neurones within the primary motor cortex (M1), and the alpha motoneurone. The aim of this investigation was to examine the excitability of intracortical neurones, CST neurones, and the alpha motoneurone, and compare these between volleyball and basketball athletes with PT and matched asymptomatic controls. METHOD: Nineteen athletes with PT and 18 asymptomatic controls participated in this cross-sectional study. Transcranial magnetic stimulation was utilized to assess CST excitability, corticospinal inhibition (silent period, and short-interval cortical inhibition). Peripheral nerve stimulation was used to evaluate lumbar spine and alpha motoneurone excitability, including the evocation of lumbar-evoked potentials and maximal compound muscle action potential (MMAX ), and CSE with central activation ratio (CAR). Knee extension MVF was also assessed. RESULTS: Athletes with PT exhibited longer silent period duration and greater electrical stimulator output for MMAX , as well as lower MVF, compared to asymptomatic controls (p < 0.05). CONCLUSION: These findings indicate volleyball and basketball athletes with PT exhibit reduced excitability of the alpha motoneurone or the neuromuscular junction, which may be linked to lower MVF. Subtle alterations at specific sites may represent compensatory changes to excitability aiming to maintain efferent drive to the knee extensors.

Behaviour change and rehabilitation adherence in adults with tendinopathy: a scoping review.

PURPOSE: This scoping review aimed to identify behaviour change strategies influencing rehabilitation adherence in adults with tendinopathy, a common musculoskeletal condition requiring prolonged rehabilitation with poor adherence and variable outcomes. METHODS: Following the Joanna Briggs Institute (JBI) methodology, seven databases were searched until April 2023. Records included reviews, intervention, and qualitative studies published in English. Behaviour change strategies were deductively coded and mapped to the capability, opportunity, and motivation model of behaviour (COM-B). RESULTS: Eighty-six articles were retained. The primary behaviour change strategies in tendinopathy rehabilitation reports addressed Psychological Capability; from knowledge through education, instruction, and self-monitoring using exercise diaries. Also, Social Opportunity involves demonstration and monitoring of rehabilitation behaviour, and Physical Opportunity focuses on time-efficient programs with access to equipment and health professionals. Few reports addressed Automatic Motivation (positive reinforcement and habit formation). Barriers identified in the reports were Reflective Motivation (negative beliefs and fears), Physical Opportunity (time-constraints), and Physical Capability (pain and comorbidities). CONCLUSIONS: Further research should explore the impact of education on beliefs, fears, and pain-management, as well as the effectiveness of teaching habit formation for improved time-management. Implementing these behaviour change strategies may enhance tendinopathy rehabilitation adherence, improving clinical trial efficacy, guiding clinical practice, and impacting patient outcomes.

Education, instruction and use of an exercise diary (Psychological Capability), demonstration and monitoring of rehabilitation behaviour (Social Opportunity), and a time-efficient program with access to equipment and a health professional (Physical Opportunity) are common behaviour change strategies to improve rehabilitation adherence.A barrier to adherence we identified was negative beliefs about capabilities and consequences, and fear of pain and causing further damage (Reflective Motivation), which may be addressed by appropriate education.Positive reinforcement and teaching habit formation (Automatic Motivation) is not present in reports and should be considered in the future.Physical Capability of tendinopathy patients to perform the rehabilitation program should not be assumed by rehabilitation professionals when prescribing and delivering rehabilitation.

Assessing calf exercise fidelity among people with Achilles tendinopathy using videos recorded via Zoom®: an observational study.

PURPOSE: Exercise fidelity is a fundamental aspect of exercise prescription by physiotherapists. Assessing exercise fidelity via telehealth (videoconference) is potentially useful but its reproducibility has not been assessed. The objective was to evaluate agreement (reproducibility) of video rating of calf exercise fidelity within (over four weeks) and between telehealth raters and compared with live rating. METHODS: Nineteen videos of participants with AT undertaking calf exercises were rated by physiotherapists in person (live) and by watching pre-recorded videos (replicating telehealth). Three forms of agreement were assessed: (i) between live assessment and recorded video (telehealth) assessment; (ii) between telehealth raters (inter-rater); (iii) agreement within telehealth raters over four weeks (intra-rater). RESULTS: There was weak to almost perfect agreement (Kappa = 0.65 to 1.00, rater 1, Kappa = 0.57 to 1.00, rater 2) between the telehealth and live raters. There was moderate to almost perfect agreement (Kappa = 0.65 to 1.00) when assessing intra-rater reliability, aside from one of the six criteria (quality of movement). CONCLUSION: Assessing calf exercise fidelity via videos recorded on Zoom® appears to demonstrate weak or greater agreement versus live rating and over time. Inter-rater agreement was lower, suggesting that the criteria developed may be better suited to use by individual raters over time.Implications for rehabilitationTelehealth assessment (when compared with live, in person assessment) shows a moderate or greater agreement for the majority of assessment criteria when assessing calf exercise fidelity.The calf exercise fidelity criteria developed can be used as an adjunct to assessment and management of people with Achilles Tendinopathy.Intra-rater assessment was shown to be moderately or more consistent over a four-week period when assessing calf exercise fidelity.

Education can reassure people with rotator cuff-related shoulder pain: a 3-arm, randomised, online experiment.

ABSTRACT: We aimed to investigate the immediate effect of best practice education (with and without pain science messages) and structure-focused education on reassurance among people with rotator cuff-related shoulder pain. We conducted a 3-arm, parallel-group, randomised experiment. People with rotator cuff-related shoulder pain were randomised (1:1:1) to (1) best practice education (highlights that most shoulder pain is not serious or a good indicator of tissue damage and recommends simple self-management strategies); (2) best practice education plus pain science messages (which attempt to improve understanding of pain); and (3) structure-focused education (highlighting that structural changes are responsible for pain and should be targeted with treatment). Coprimary outcomes were self-reported reassurance that no serious condition is causing their pain and continuing with daily activities is safe. Secondary outcomes measured management intentions, credibility and relevance of the education, and similarity to previous education. Two thousand two hundred thirty-seven participants were randomised and provided primary outcome data. Best practice education increased reassurance that no serious condition is causing their pain (estimated mean effect 0.5 on a 0-10 scale, 95% confidence interval [CI] 0.2-0.7) and continuing with daily activities is safe (0.6, 95% CI 0.3-0.8) compared with structure-focused education . Adding pain science messages to best practice education slightly increased both measures of reassurance (0.2, 95% CI 0.0-0.4). Clinicians treating patients with rotator cuff-related shoulder pain should highlight that most shoulder pain is not serious or a good indicator of tissue damage and recommend simple self-management strategies. The benefit of adding pain science messages is small.

An automated method for tendon image segmentation on ultrasound using grey-level co-occurrence matrix features and hidden Gaussian Markov random fields.

BACKGROUND: Despite knowledge of qualitative changes that occur on ultrasound in tendinopathy, there is currently no objective and reliable means to quantify the severity or prognosis of tendinopathy on ultrasound. OBJECTIVE: The primary objective of this study is to produce a quantitative and automated means of inferring potential structural changes in tendinopathy by developing and implementing an algorithm which performs a texture based segmentation of tendon ultrasound (US) images. METHOD: A model-based segmentation approach is used which combines Gaussian mixture models, Markov random field theory and grey-level co-occurrence (GLCM) features. The algorithm is trained and tested on 49 longitudinal B-mode ultrasound images of the Achilles tendons which are labelled as tendinopathic (24) or healthy (25). Hyperparameters are tuned, using a training set of 25 images, to optimise a decision tree based classification of the images from texture class proportions. We segment and classify the remaining test images using the decision tree. RESULTS: Our approach successfully detects a difference in the texture profiles of tendinopathic and healthy tendons, with 22/24 of the test images accurately classified based on a simple texture proportion cut-off threshold. Results for the tendinopathic images are also collated to gain insight into the topology of structural changes that occur with tendinopathy. It is evident that distinct textures, which are predominantly present in tendinopathic tendons, appear most commonly near the transverse boundary of the tendon, though there was a large variability among diseased tendons. CONCLUSION: The GLCM based segmentation of tendons under ultrasound resulted in distinct segmentations between healthy and tendinopathic tendons and provides a potential tool to objectively quantify damage in tendinopathy.

Co-development and evaluation of the Musculoskeletal Telehealth Toolkit for physiotherapists.

INTRODUCTION: In-person physiotherapy services are not readily available to all individuals with musculoskeletal conditions, especially those in rural regions or with time-intensive responsibilities. The COVID-19 pandemic highlighted that telehealth may facilitate access to, and continuity of care, yet many physiotherapists lack telehealth confidence and training. This project co-developed and evaluated a web-based professional development toolkit supporting physiotherapists to provide telehealth services for musculoskeletal conditions. METHODS: A mixed-methods exploratory sequential design applied modified experience-based co-design methods (physiotherapists [n = 13], clinic administrators [n = 2], and people with musculoskeletal conditions [n = 7]) to develop an evidence-informed toolkit. Semi-structured workshops were conducted, recorded, transcribed, and thematically analysed, refining the toolkit prototype. Subsequently, the toolkit was promoted via webinars and social media. The usability of the toolkit was examined with pre-post surveys examining changes in confidence, knowledge, and perceived telehealth competence (19 statements modelled from the theoretical domains framework) between toolkit users (>30 min) and non-users (0 min) using chi-squared tests for independence. Website analytics were summarised. RESULTS: Twenty-two participants engaged in co-design workshops. Feedback led to the inclusion of more patient-facing resources, increased assessment-related visual content, streamlined toolkit organisation, and simplified, downloadable infographics. Three hundred and twenty-nine physiotherapists from 21 countries completed the baseline survey, with 172 (52%) completing the 3-month survey. Toolkit users had greater improvement in knowledge, confidence, and competence than non-users in 42% of statements. Seventy-two percentage of toolkit users said it changed their practice, and 95% would recommend the toolkit to colleagues. During the evaluation period, the toolkit received 5486 total views. DISCUSSION: The co-designed web-based Musculoskeletal Telehealth Toolkit is a professional development resource that may increase physiotherapist's confidence, knowledge, and competence in telehealth.

Patient experiences of rotator cuff-related shoulder pain and their views on diagnostic shoulder imaging: a qualitative study.

PURPOSE: To explore patient experiences of rotator cuff-related shoulder pain, and their views on the role and value of diagnostic shoulder imaging. MATERIALS AND METHODS: Semi-structured interviews were conducted with 20 patients with shoulder pain exploring the impact and management of their shoulder condition, reasons for and experiences of diagnostic imaging, and feelings about and responses to diagnostic imaging findings. Framework analysis was used to analyse the dataset. RESULTS: Five themes were identified [1]: Lived experience and beliefs about pain and movement [2]; Contextualisation of imaging findings by health professionals is more important than the imaging report [3]; Factors influencing whether and when to have imaging [4]; Imaging can identify the actual problem and guide treatment; and [5] Treatment responses and treatment decision making. CONCLUSION: Patients commonly believe imaging is needed to formulate a diagnosis. There was minimal concern about potential indirect harms that could arise (e.g., inappropriate diagnosis leading to unnecessary treatments). The context of the diagnostic imaging reports (i.e., what needed to be done) was perceived as more important than the exact meaning of the imaging findings. Patients felt that the diagnostic imaging confirmed their existing biomedical beliefs, and these beliefs were not challenged by their healthcare professionals.IMPLICATIONS FOR REHABILITATIONPatients with shoulder pain may believe imaging is necessary for diagnosis and defining treatment yet do not consider potential indirect harms (e.g., unnecessary treatment for findings that are not relevant).Health professionals should ensure patients are aware of imaging limitations and harms and facilitate shared decision-making about whether to have imaging.Health professionals also have an important role in the appropriate contextualisation of imaging findings (i.e., they do not necessarily relate to pain nor guide treatment).

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.

Monitoring physical activity using wearable technology in people with Achilles tendinopathy undergoing physiotherapy treatment: A feasibility prospective cohort study.

OBJECTIVES: Physical activity modification is an important part of the management of Achilles tendinopathy. However, to our knowledge, there is a lack of evidence on objective physical activity assessment in Achilles tendinopathy. The purpose of this study is to (1) assess feasibility of using an inertial measurement unit (IMU) to monitor physical activity and IMU-derived biomechanical measures over 12-week treatment course by a physiotherapist; (2) conduct a preliminary analysis of changes in physical activity over 12-weeks. DESIGN: A feasibility prospective cohort study SETTING: A community setting. PARTICIPANTS: People with Achilles tendinopathy who had recently commenced (≤2 sessions), or were about to commence, treatment with a physiotherapist MAIN OUTCOME MEASURES: Participants wore a shank-mounted IMU on the affected side for one week at baseline, 6-, and 12-week follow-ups. The outcomes were pain/symptom severity, IMU-derived physical activity and biomechanical measures (stride rate, peak shank angular velocity, and peak shank acceleration). RESULTS: Thirty participants were recruited. There was a high retention rate (97%), response rate (97%), and IMU wear compliance at each timepoint (>93%). For pain/symptom severity, a significant time effect was observed between baseline and 12-week follow-up. Physical activity and IMU-derived biomechanical measures did not change over 12 weeks. Physical activity decreased at the 6-week follow-up but only returned to the baseline level at 12-week follow-up. CONCLUSIONS: A larger-scale cohort study assessing clinical outcomes and physical activity appears feasible. Preliminary data indicate that physical activity may not change significantly over 12-weeks in people undergoing physiotherapy management for Achilles tendinopathy. CONTRIBUTION OF THE PAPER.

Exercise adherence in trials of therapeutic exercise interventions for common musculoskeletal conditions: A scoping review.

OBJECTIVE: The aims of the scoping review were to: (1) evaluate how commonly trialists assess and report adherence to exercise intervention for common musculoskeletal conditions and (2) report the levels of adherence to exercise for musculoskeletal conditions and whether this was influenced by variables of interest. METHODS: Medline, Cinahl, Embase, Emcare, and SPORTDiscus databases were searched using predefined terms. Published randomised controlled trials were included. Trials were included if they investigated the effectiveness of an exercise intervention for low back pain, shoulder pain, Achilles tendinopathy and knee osteoarthritis (we selected a priori as indicative common musculoskeletal conditions). Data extraction was performed independently by teams of two reviewers. Descriptive consolidation and qualitative synthesis were performed. RESULTS: 321 trials were included; less than half (46.7%, 150/321) measured adherence. When adherence was assessed, 21% (31/150) of trials did not report the results. Adherence levels were greater when people were supervised. Reporting adherence was more common in registered trials. Adherence was measured most frequently via self-report (47.3%, 71/150) followed by supervised sessions (32.0%, 48/150) or combination of both (20.7%, 31/150). The majority of trials (97.0%, 97/100) reported the level of adherence in terms of a frequency. CONCLUSIONS: A majority of trials investigating exercise interventions for common musculoskeletal conditions do not assess exercise adherence. Trials that were registered reported exercise adherence more frequently. The majority of trials measure adherence via self-report with reliance on only one dimension of exercise adherence (frequency).

Evidence for Improvement in Local but Not Diffuse Pressure Pain Thresholds Following Physical Therapist Interventions for Tendinopathy: A Systematic Review.

OBJECTIVES: The objectives of this study were to investigate whether quantitative sensory testing proxy measures for peripheral and central sensitization change following physical therapist interventions for tendinopathy and whether changes occur in parallel to changes in self-reported pain. METHODS: Four databases-Ovid EMBASE, Ovid MEDLINE, CINAHL Plus, and CENTRAL-were searched from inception to October 2021. Three reviewers extracted data for the population, tendinopathy, sample size, outcome, and physical therapist intervention. Studies that reported quantitative sensory testing proxy measures and pain at baseline and another time point following a physical therapist intervention were included. Risk of bias was assessed using the Cochrane Collaboration's tools and the Joanna Briggs Institute checklist. Levels of evidence were assessed using the Grading of Recommendations Assessment, Development and Evaluation. RESULTS: Twenty-one studies were included and all investigated changes in pressure pain threshold (PPT) at either local and/or diffuse sites. Change in other proxy measures of peripheral and central sensitization were not investigated among any studies. Diffuse PPT did not demonstrate significant change in all trial arms that reported this outcome. Local PPT improved for 52% of trial arms, and it was more likely to change at the medium (63%) and longer (100%) compared with the immediate (36%) and short (50%) timepoints. On average, 48% of trial arms demonstrated parallel changes in either outcome. Pain improvement was more frequent than local PPT improvement at all timepoints except for the longest. CONCLUSION: Local PPT may improve among people receiving physical therapist interventions for tendinopathy, but these changes appear to lag behind changes in pain. Change in diffuse PPT among people with tendinopathy has been infrequently investigated in the literature. IMPACT: The findings of the review contribute to knowledge of how tendinopathy pain and PPT change with treatments.

The relationship between psychological, cognitive, and contextual factors and rehabilitation outcomes in Achilles tendinopathy: A prospective feasibility cohort study.

OBJECTIVES: This study aimed to investigate the feasibility of conducting a full-scale study investigating the influence of patient-related factors on rehabilitation outcomes in Achilles tendinopathy (AT). A secondary aim was to investigate preliminary relationships between patient-related factors and clinical outcomes at 12- and 26- weeks. DESIGN: feasibility cohort. SETTING: Australian healthcare settings. METHODS: Participants with AT receiving physiotherapy in Australia were recruited via treating physiotherapists and online. Data were collected online at baseline, 12- and 26-weeks. Progression criteria for a full-scale study were recruitment rate of ≥10 per month, conversion rate ≥20%, and response rate to questionnaires ≥80%. The relationship between patient-related factors and clinical outcomes was investigated using Spearman's rho correlation coefficient. RESULTS: The average recruitment rate was 5/month, conversion rate was 97%, and response rate to questionnaires was ≥97% at all timepoints. There was a fair to moderate correlation (rho = 0.225 to 0.683) between patient-related factors and clinical outcomes at the 12-week, but no to weak correlation at the 26-week (rho = 0.002 to 0.284). CONCLUSIONS: Feasibility outcomes suggest a future full-scale cohort study is feasible with the caveat of utilizing strategies to improve recruitment rate. Preliminary bivariate correlations at 12-weeks warrant further investigations in larger studies.

Achilles tendon forces and pain during common rehabilitation exercises in male runners with Achilles tendinopathy. A laboratory study.

OBJECTIVES: To estimate Achilles tendon forces and their relationship with self-reported pain in runners with Achilles tendinopathy (AT) during common rehabilitation exercises. DESIGN: Cross-sectional. SETTING: Laboratory. PARTICIPANTS: 24 recreational male runners (45.92 (8.24) years old; 78.20 (8.01) kg; 177.17 (6.69) cm) with symptomatic AT. MAIN OUTCOME MEASURES: Kinematic and kinetic data were collected to estimate Achilles tendon forces during 12 commonly prescribed exercises. Achilles tendon forces were estimated from biomechanical data and normalised to the participant's bodyweight. The secondary aim was to investigate the relationship between Achilles tendon forces and pain during these exercises. RESULTS: Two exercise clusters were identified based on Achilles tendon forces. Cluster1 included various exercises including double heel raises, single heel raises, and walking (range: 1.10-2.76 BWs). Cluster2 included running, jumping and hopping exercises (range: 5.13-6.35 BWs). Correlation between tendon forces and pain was at best low for each exercise (range: -0.43 - 0.20). Higher force exercises lead to more tendon load for a given amount of pain (R2 = 0.7505; y = 0.2367x + 0.6191). CONCLUSION: This study proposes a hierarchical exercise progression based on Achilles tendon forces to guide treatment of runners with AT. Achilles tendon forces and pain are not correlated in runners with AT.
