Objectives: Following anterior cruciate ligament reconstruction (ACLR), maladaptive changes occur in the motor cortex representation of the quadriceps, evidenced by increases in intracortical inhibition and facilitation. The primary objective of this proof-of-concept study was to determine if anodal transcranial direct current stimulation (tDCS) can alter quadriceps intracortical inhibition and facilitation in an early-ACLR population after 6 weeks of application during exercise., Methods: We performed a randomised, triple-blind controlled trial for proof of concept comparing anodal-tDCS to sham-tDCS following ACLR. Anodal-tDCS or sham-tDCS was delivered to the primary motor cortex for 20 min, three times per week, for 6 weeks from week 2 post ACLR. Transcranial magnetic stimulation quantified quadriceps short-interval intracortical inhibition (SICI), long-interval intracortical inhibition (LICI) and short-interval intracortical facilitation (SICF). Significance at p<0.05., Results: Participants were randomised to anodal (n=11) or sham (n=10) tDCS. Participants were predominantly male (n=13) and had a mean (SD) age of 24.4 (4.7) years. For SICI, there was a group-by-time effect for anodal-tDCS (β=0.519, 95% CI 0.057 to 0.981, p=0.028) and an effect for time (β=-1.421, 95% CI -1.919 to -0.923, p<0.001). For LICI, there was no group-by-time (β=-0.217, 95% CI -0.916 to 0.482, p=0.543) or time effect (β=0.039, 95% CI -0.815 to -0.893, p=0.928). For SICF, there was a group-by-time effect for anodal-tDCS (β=-0.764, 95%CI -1.407 to -0.120, p=0.020) but not time (β=0.504, 95% CI -0.627 to 1.635, p=0.383)., Conclusion: This study provided proof of the efficacy of anodal-tDCS post ACLR in reducing maladaptive quadriceps inhibition and facilitation. We demonstrated anodal-tDCS improved facilitation and inhibition post ACLR, which are drivers of arthrogenic muscle inhibition., Competing Interests: This study was supported by the Orthopaedic Research Foundation of Western Australia whose funding purchased the tDCS devices and a Western Australian Department of Health Innovation Near-Miss Award., (Copyright © Author(s) (or their employer(s)) 2024.

Background: The 17-item Tampa Scale for Kinesiophobia (TSK) is a commonly used patient-reported outcome measure (PROM) to assess kinesiophobia, but the measurement properties of the TSK in people with femoroacetabular impingement syndrome (FAIS) are unknown., Objectives: 1) Revise the existing TSK by removing items, as needed, with inadequate functioning to optimise the TSK for people with FAIS, and 2) evaluate construct validity (both structural validity and hypothesis testing), internal consistency, and minimal important change., Methods: Cross-sectional cohort study including 153 young adults with FAIS. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to evaluate structural validity and the TSK was revised to remove items with poor function, improving CFA model fit. Hypothesis testing, internal consistency (Cronbach's α) and minimal important change (distribution-based method) were also evaluated., Results: A 7-item version of the TSK provided the best CFA model fit with 10-items functioning poorly and needing to be removed. The 7-item TSK was uni-dimensional (single factor in EFA) and had adequate structural validity (Standardised Root Measure Square = 0.0771). The 7-item TSK had insufficient hypothesis testing with moderate correlations to 8/14 PROMs measuring different constructs. The 7-item TSK had adequate internal consistency (α = 0.783). The minimal important change of the 7-item TSK was 6.00 points (0-100 point scale)., Conclusion: We found that the '7-item TSK for FAIS', had superior structural validity to the original 17-item scale, suggesting that it may be more appropriate for use in this population. Further studies should evaluate other measurement properties of the 7-item scale., Competing Interests: Declaration of competing interest Myles C Murphy, Ebonie K Rio, Mark J Scholes, Sally L Coburn, Denise M Jones, Marcella Pazzinatto, Richard TR Johnston, and Joanne L Kemp declare no competing interests related to this research., (Copyright © 2024 The Authors.

To develop a core outcome set for Achilles tendinopathy (COS-AT) for use in clinical trials we performed a five-step process including (1) a systematic review of available outcome measurement instruments, (2) an online survey on truth and feasibility of the available measurement instruments, (3) an assessment of the methodological quality of the selected outcome measurement instruments, (4) an online survey on the outcome measurement instruments as COS and (5) a consensus in-person meeting. Both surveys were completed by healthcare professionals and patients. The Outcome Measures in Rheumatology guidelines with a 70% threshold for consensus were followed. We identified 233 different outcome measurement instruments from 307 included studies; 177 were mapped within the International Scientific Tendinopathy Symposium Consensus core domains. 31 participants (12 patients) completed the first online survey (response rate 94%). 22/177 (12%) outcome measurement instruments were deemed truthful and feasible and their measurement properties were evaluated. 29 participants (12 patients) completed the second online survey (response rate 88%) and three outcome measurement instruments were endorsed: the Victorian Institute of Sports Assessment-Achilles questionnaire, the single-leg heel rise test and evaluating pain after activity using a Visual Analogue Scale (VAS, 0-10). 12 participants (1 patient) attended the final consensus meeting, and 1 additional outcome measurement instrument was endorsed: evaluating pain during activity/loading using a VAS (0-10). It is recommended that the identified COS-AT will be used in future clinical trials evaluating the effectiveness of an intervention. This will facilitate comparing outcomes of intervention strategies, data pooling and further progression of knowledge about AT. As COS-AT is implemented, further evidence on measurement properties of included measures and new outcome measurement instruments should lead to its review and refinement., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Hop testing is widely used by clinicians to monitor rehabilitation and decide when to return to sport following anterior cruciate ligament reconstruction (ACLR); however, the trajectory of long-term hop performance has not been summarised., Objective: To investigate hop performance change over time after ACLR., Design: Systematic review with longitudinal meta-analysis., Data Sources: MEDLINE, EMBASE, CINAHL, Scopus, Cochrane CENTRAL and SPORTDiscus to 28 February 2023., Eligibility Criteria: Studies with ≥ 50 participants following primary ACLR, with mean participant age of 18-40 years, reporting a quantitative measure of hop performance (e.g. single forward hop distance). Results had to be reported for the ACLR limb and compared with (1) the contralateral limb (within person) and/or (2) an uninjured control limb (between person)., Results: We included 136 studies of 23,360 participants. Performance was similar across different hop tests, with steep initial improvements in within-person symmetry, tailing off after 18-24 months. ACLR limb hop performance was 5-10% lower compared with the contralateral limb at 1 year post-surgery, with largest deficits observed for vertical hop [87.0% contralateral limb (95% CI 85.3-88.8) compared with single forward hop 93.8% (95% CI 92.8-94.9)]. By 3-5 years, results were similar between ACLR and contralateral limbs. There were limited data for between-person comparisons (n = 17 studies). Exploratory analyses showed deficits in all forward hopping tests to be very strongly correlated with each other [e.g. single forward and triple hop rho = 0.96 (95% CI 0.90-0.99)], though there was discordance in the relationship between single forward hop and vertical hop performance [rho = 0.27 (95% CI - 0.53 to 0.79)]., Conclusions: Hop performance is comparable to the uninjured limb by 3-5 years post-ACLR, with the greatest deficits in within-person symmetry present in vertical and side hop tests. Assessment of hopping in multiple planes and comparison with uninjured controls, may provide the most complete evaluation of functional performance., (© 2024. The Author(s).)

Objective: This study aimed to investigate how knee extensor and flexor strength change over time after anterior cruciate ligament reconstruction (ACLR)., Design: Systematic review with longitudinal meta-analysis., Data Sources: Medline, Embase, CINAHL, Scopus, Cochrane CENTRAL and SPORTDiscus to 28 February 2023., Eligibility Criteria: Studies of primary ACLR (n≥50), with mean participant age 18-40 years, reporting a quantitative measure of knee extensor or flexor strength were eligible. Muscle strength had to be reported for the ACL limb and compared with: (1) the contralateral limb (within-person); and/or (2) an uninjured control limb (between-person)., Results: We included 232 studies of 34 220 participants. Knee extensor and flexor strength showed sharp initial improvement postoperatively before tailing off at approximately 12-18 months post surgery with minimal change thereafter. Knee extensor strength was reduced by more than 10% compared with the contralateral limb and approximately 20% compared with uninjured controls at 1 year for slow concentric, fast concentric and isometric contractions. Knee flexor strength showed smaller deficits but was still 5%-7% lower than the contralateral limb at 1 year for slow concentric, fast concentric and isometric contractions. Between-person comparisons showed larger deficits than within-person comparisons., Conclusion: Knee extensor muscle strength is meaningfully reduced (>10%) at 1 year, with limited improvement after this time up to and beyond 5 years post surgery. Many people likely experience persistent and potentially long-term strength deficits after ACLR. Comparison within person (to the contralateral limb) likely underestimates strength deficits in contrast to uninjured controls., Competing Interests: Competing interests: KMC holds a research grant from Levin Health.

We aimed to report the trajectory of self-reported outcomes up to 11 years post-ACLR. We also explored the relationship between hop performance at 1 year and: (i) future self-reported knee outcomes; and (ii) risk of subsequent knee events. 124 participants (43 women, mean age 31 ± 8 years) were recruited at 1 year following hamstring-autograft ACLR. Hop performance was assessed with single-forward and side-hop tests. Follow-up was completed at 3 (n = 114), 5 (n = 89) and 11 years (n = 72) post-ACLR. Self-reported outcomes were assessed at each follow-up with the Knee injury Osteoarthritis Outcome Score (KOOS) pain and quality of life (QOL) subscales. Generalized linear mixed models estimated the relationship between hop performance and self-reported outcomes. Subsequent knee events (new injury/surgery) to either knee were recorded, with the relationship between hop performance and risk of subsequent knee events analyzed with Cox proportional hazards. Self-reported knee outcomes were stable (mean change < 10 points) across all timepoints but with major within-sample variability. There was a modest relationship between greater hop performance at 1 year and better future KOOS-pain (average marginal effect [AME] % improvement with + 1 cm single forward hop = 0.06% [95% CI 0.02-0.10]). A nonlinear spline relationship showed better single-forward hop performance was associated with better KOOS-QOL for scores < 108 cm, not present for higher hop scores > 108 cm. There were 21 index and 11 contralateral subsequent knee events. Hop performance was not related to risk of a subsequent knee event (hazard ratio index knee 0.99 [95% CI 0.98-1.02]). In conclusion, self-reported knee pain and quality of life were generally stable across the 11-year follow-up period. Greater hop performance at 1-year post-ACLR was related to better self-reported knee outcomes up to 11-year follow-up (of questionable clinical importance), but not associated with the risk of subsequent knee injury/surgery., (© 2024 The Author(s).

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., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

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., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

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., Competing Interests: Declaration of competing interest The authors declare no competing interests., (Copyright © 2024 The Authors.

Objective: We aimed to determine hip and lower-leg muscle strength in people after ACL injury compared with an uninjured control group (between people) and the uninjured contralateral limb (between limbs)., Design: Systematic review with meta-analysis., Data Sources: MEDLINE, EMBASE, CINAHL, Scopus, Cochrane CENTRAL and SportDiscus to 28 February 2023., Eligibility Criteria: Primary ACL injury with mean age 18-40 years at time of injury. Studies had to measure hip and/or lower-leg muscle strength quantitatively (eg, dynamometer) and report muscle strength for the ACL-injured limb compared with: (i) an uninjured control group and/or (ii) the uninjured contralateral limb. Risk of bias was assessed according to Cochrane Collaboration domains., Results: Twenty-eight studies were included (n=23 measured strength ≤12 months post-ACL reconstruction). Most examined hip abduction (16 studies), hip extension (12 studies) and hip external rotation (7 studies) strength. We found no meaningful difference in muscle strength between people or between limbs for hip abduction, extension, internal rotation, flexion or ankle plantarflexion, dorsiflexion (estimates ranged from -9% to +9% of comparator). The only non-zero differences identified were in hip adduction (24% stronger on ACL limb (95% CI 8% to 42%)) and hip external rotation strength (12% deficit on ACL limb (95% CI 6% to 18%)) compared with uninjured controls at follow-ups >12 months, however both results stemmed from only two studies. Certainty of evidence was very low for all outcomes and comparisons, and drawn primarily from the first year post-ACL reconstruction., Conclusion: Our results do not show widespread or substantial muscle weakness of the hip and lower-leg muscles after ACL injury, contrasting deficits of 10%-20% commonly reported for knee extensors and flexors. As it is unclear if deficits in hip and lower-leg muscle strength resolve with appropriate rehabilitation or no postinjury or postoperative weakness occurs, individualised assessment should guide training of hip and lower-leg strength following ACL injury., Prospero Registration Number: CRD42020216793., Competing Interests: Competing interests: KMC holds a research grant from Levin Health.

SYNOPSIS:   JOSPT is starting 2024 on a high, with a tendinopathy-focused edition that showcases more of the high-quality tendinopathy research you know and love in systematic reviews, original research articles, a consensus paper, and editorials. As any athlete knows, a good warm-up is crucial to performing well at the main event. Here, we help you warm up and prime your brain to take on all the content of this tendinopathy-focused issue of the Journal. J Orthop Sports Phys Ther 2024;54(1):1-2.

OBJECTIVE: To explore whether people with lower-limb tendinopathy have reduced relative conditioned pain modulation (CPM) when compared to nontendinopathy controls. DESIGN: Systematic review with individual participant data (IPD) meta-analysis. LITERATURE SEARCH: Eight databases were searched until August 29, 2022. STUDY SELECTION CRITERIA: Cross-sectional studies comparing the magnitude of the CPM effect in people with lower-limb tendinopathy to nontendinopathy controls in a case-control design. DATA SYNTHESIS: Included studies provided IPD, which was reported using descriptive statistics. Generalized estimating equations (GEEs) determined between-group differences in the relative CPM effect, when adjusting for co-variables. Study quality was assessed using a Joanna Briggs Institute checklist, and certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluations. RESULTS: Five records were included, IPD were provided for 4 studies (n = 219 with tendinopathy, n = 226 controls). The principal GEE (model 1) found no significant relative CPM effects for tendinopathy versus controls (B = -1.73, P = .481). Sex (B = 4.11, P = .160), age (B = -0.20, P = .109), and body mass index (B = 0.28, P = .442) did not influence relative CPM effect. The Achilles region had a reduced CPM effect (B = -22.01, P = .009). In model 2 (adjusting for temperature), temperature (B = -2.86, P = .035) and female sex (B = 21.01, P = .047) were associated with the size of the relative CPM effect. All studies were low-quality, and the certainty of the evidence was moderate. CONCLUSION: There were no between-group differences in the magnitude of the CPM effect, suggesting clinicians should manage lower-limb tendinopathy using interventions appropriate for peripherally dominant pain (eg, tendon loading exercises such as heavy slow resistance). Based on the "moderate"-certainty evidence, future studies are unlikely to substantially change these findings. J Orthop Sports Phys Ther 2023;54(1):1-10.

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.

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.

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.

Introduction: Following ACL reconstruction (ACLR), deficits in hip muscle strength and relationships to future outcomes are unknown., Methods: 111 participants one year after ACLR, completed hip external rotation (ER) and internal rotation (IR) strength assessment. At 1 (n = 111) and 5 (n = 74) years post-ACLR, participants completed a battery of functional, symptomatic (Knee Osteoarthritis Outcome Score (KOOS)) and structural assessments (radiography, magnetic resonance imaging (MRI)). Cartilage health of the patellofemoral and tibiofemoral compartments was assessed with the semiquantitative MRI Osteoarthritis Knee Score. Hip rotation strength was compared between-limbs, and relationships between hip strength at 1 year and functional, symptomatic and cartilage outcomes at 1 and 5 years were investigated with regression models., Results: The index (ACLR) limb had weaker hip ER (but not IR) strength compared to the contralateral side (standardised mean difference ER = -0.33 (95%CI -0.60, -0.07; IR = -0.11 (95%CI -0.37, 0.15). Greater hip ER and IR strength was associated with superior function at 1 and 5 years, and better KOOS-Patellofemoral symptoms at 5 years. Greater hip ER strength was associated with lower odds of worsening tibiofemoral cartilage lesions at 5 years (odds ratio 0.01, 95%CI 0.00, 0.41)., Conclusion: Hip rotation strength may play a role in worsening function, symptoms and cartilage health after ACLR., Competing Interests: Declaration of competing interest Ali Guermazi is a shareholder of Boston Imaging Core Lab, LLC, and a consultant to Merck Serono, Pfizer, GE Healthcare, Galapagos, Roche and TissueGene.

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., Systematic Review Registration: PROSPERO (registration number: CRD42020149970)., Competing Interests: Declaration of interest statement MM, MT, JD and SD have received speaker fees for lectures on tendinopathy. ER has received speaker fees for lectures on tendinopathy and has designed an app for anterior knee pain rehabilitation. PC and WG declare that they have no conflict of interest.

Objectives: We aimed to determine (1) the proportion of women authors overall, in first (lead) and last (senior) author positions, (2) the proportion of women research participants and (3) the association between women in first and/or last author positions and the proportion of women research participants in original research articles and editorials/opinion pieces in four sport and exercise medicine/physiotherapy journals., Methods: The journals evaluated were the British Journal of Sports Medicine , Journal of Orthopaedic and Sports Physical Therapy , Physical Therapy in Sport and International Journal of Sports Physical Therapy .We reviewed all original research articles and editorials/opinion pieces published in 2008, 2009, 2018 and 2019. For each, we aimed to determine the gender/sex of all authors (through gender pronouns, Google Scholar, ResearchGate, institutional profiles, personal websites, photographs and/or social media), and the gender/sex of study participants reported as 'female' or 'male' or 'women' or 'men' or 'girls' or 'boys'., Results: We included 952 original studies and 219 editorials/opinion pieces. There were 5146 authors of original studies and 706 authors of editorials/opinion pieces. Compared with 2008/2009, the proportion of women as first and last authors was 3.6% (33.0% compared with 29.4%) and 4.8% (33.2% compared with 27.4%) higher respectively in 2018/2019. On average, the proportion of women participants in original studies remained largely unchanged over the 10-year period, only 10% of all participants were women in studies., Conclusion: Women are strikingly under-represented in first and last author positions, as are women participants in sports and exercise medicine/physiotherapy journals., Competing Interests: Competing interests: CLA has served as editor-in-chief for JOSPT (Journal of Orthopaedic and Sports Physical Therapy) since 2018.

Objective: The purpose of this study was to compare the efficacy of physical therapy delivered via an all telehealth or hybrid format with an all in-person format on movement-evoked pain for individuals with chronic Achilles tendinopathy (AT)., Methods: Sixty-six individuals with chronic AT participated (age, 43.4 [SD = 15.4] years; 56% female; body mass index, 29.9 [SD = 7.7] kg/m2). Participants completed all in-person visits from the initiation of recruitment in September 2019 to March 16, 2020 (in-person group). From March 17 to July 15, 2020, participants completed all telehealth visits (telehealth group). From July 16, 2020, to enrollment completion in December 2020, participants could complete visits all in-person, all telehealth, or a combination of in-person and telehealth (hybrid group) based on their preference. A physical therapist provided 6 to 7 visits, including an exercise program and patient education. Noninferiority analyses of the telehealth and hybrid groups compared with the in-person group were completed for the primary outcome of movement-evoked pain during single-limb heel raises., Results: All groups demonstrated decreases in movement-evoked pain beyond the minimal clinically important difference from baseline to 8 weeks (2 out of 10 on a numeric pain rating scale). Lower bounds of the 95% CIs for mean differences between groups did not surpass the preestablished noninferiority margin (2 out of 10) for movement-evoked pain in both the telehealth and hybrid groups (telehealth vs in-person: 0.45 [-1.1 to 2.0]; hybrid vs in-person: 0.48 [-1.0 to 1.9])., Conclusion: Individuals with chronic AT who completed a tendon-loading program with patient education through a telehealth or hybrid format had no worse outcomes for pain than those who received the same intervention through in-person visits., Impact: Physical therapist-directed patient care delivered via telehealth may enhance accessibility to best practice AT rehabilitation, including exercise and education. Use of telehealth technology may also provide an opportunity to prioritize patient preference for physical therapy visit format., Lay Summary: If you are a patient with chronic AT, physical therapist-directed patient care delivered via telehealth may improve your accessibility to best practice AT rehabilitation, including exercise and education. Use of telehealth technology may also prioritize your preferences regarding the format of the physical therapy visit., (© The Author(s) 2023.

Abstract: Exercise is the standard of care for Achilles tendinopathy (AT), but 20% to 50% of patients continue to have pain following rehabilitation. The addition of pain science education (PSE) to an exercise program may enhance clinical outcomes, yet this has not been examined in patients with AT. Furthermore, little is known about how rehabilitation for AT alters the fear of movement and central nervous system nociceptive processing. Participants with chronic AT (N = 66) were randomized to receive education about AT either from a biopsychosocial (PSE) or from a biomedical (pathoanatomical education [PAE]) perspective. Simultaneously, all participants completed an exercise program over 8 weeks. Linear mixed models indicated that there were no differences between groups in (1) movement-evoked pain with both groups achieving a clinically meaningful reduction (mean change [95% CI], PSE: -3.0 [-3.8 to -2.2], PAE = -3.6 [-4.4 to -2.8]) and (2) self-reported function, with neither group achieving a clinically meaningful improvement (Patient-Reported Outcomes Measurement Information System Physical Function-PSE: 1.8 [0.3-3.4], PAE: 2.5 [0.8-4.2]). After rehabilitation, performance-based function improved (number of heel raises: 5.2 [1.6-8.8]), central nervous system nociceptive processing remained the same (conditioned pain modulation: -11.4% [0.2 to -17.3]), and fear of movement decreased (Tampa Scale of Kinesiophobia, TSK-17: -6.5 [-4.4 to -8.6]). Linear regression models indicated that baseline levels of pain and function along with improvements in self-efficacy and knowledge gain were associated with a greater improvement in pain and function, respectively. Thus, acquiring skills for symptom self-management and the process of learning may be more important than the specific educational approach for short-term clinical outcomes in patients with AT., (Copyright © 2022 International Association for the Study of Pain.)

Objectives: To examine the effects of 15 min of high intensity treadmill running on concussion testing assessed by the King-Devick test., Design: Prospective Cohort Study., Methods: Participants self-selected to either a running or a control group. At baseline both groups were assessed using the King-Devick concussion test. The running group then completed 15-minutes of treadmill running at rating of perceived exertion of 7-9/10 while the control group sat quietly. Both groups repeated the King-Devick test following that 15-minute period., Results: Participants (n = 84 men, 53 women) were divided in two groups; running or control. Both groups, on average, had significant improvement after 15 min (suggesting a learning effect). Comparisons between the baseline and re-assessment scores indicated impaired performance was more common following high intensity treadmill running (n = 23 participants, 34.3%) compared to the control group (n = 10 participants, 14.3%, p = 0.006, OR = 3.44 [95%CI 1.40-8.50]). Four participants in the running group worsened their score at reassessment by more than 3 s compared to no participants in the control group., Conclusions: After 15 min of high intensity treadmill running, 1 in 3 participants scored a slower time at follow-up or committed a mistake compared to baseline. Implications for clinical practise include: the recommendation that baseline tests be conducted at rest and after high intensity exercise to provide accurate comparisons to assist in clinical decision making; and a cut-off of >3 s may be a clinically useful difference between resting baseline and re-assessment using the King-Devick test., Competing Interests: Declaration of interest statement The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Sports Medicine Australia.

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., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: There is no evidence whether kinesiophobia affects women and men with femoroacetabular impingement (FAI) syndrome differently., Objective: To explore the association between kinesiophobia, quality of life (QoL), pain, and physical function in people with FAI syndrome, and to compare the level of kinesiophobia between women and men with FAI syndrome., Methods: One-hundred-fifty participants with FAI syndrome (51% women) completed assessment of the following: kinesiophobia with the Tampa Scale for Kinesiophobia; patient reported outcome measures (PROMs) (pain, physical function, health- and hip-related QoL); physical function (side bridge, hop for distance, and one leg rise); and active hip range of motion (flexion, external rotation, internal rotation)., Results: Greater kinesiophobia was correlated with worse hip-related QoL (rho=-0.58; p<0.001), self-reported physical function (rho=-0.42; p<0.001), health-related QoL (rho=-0.46; p<0.001), and pain levels (rho=-0.46; p<0.001). In women, kinesiophobia was also associated with worse physical function (hop for distance r=-0.38; p=0.001 and side bridge rho=-0.24; p=0.036) explaining 36% of the variation of the hip-related QoL, 29% of the health-related QoL, and 27% of the self-reported physical function. In men, kinesiophobia explained 35%, 12%, and 10%, respectively., Conclusion: In people with FAI syndrome, greater kinesiophobia was associated with worse PROMs, but not with hip range of motion. No sex-related differences in mean kinesiophobia scores were found. In women, an association was found between kinesiophobia and worse performance in physical tests. These findings might indicate that kinesiophobia plays a more important role in the clinical presentation of women with FAI syndrome than men., Competing Interests: Conflicts of interest None to declare., (Copyright © 2022 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia.

Objective: To determine if impairment in motor imagery processes is present in Achilles tendinopathy (AT), as demonstrated by a reduced ability to quickly and accurately identify the laterality (left-right judgement) of a pictured limb. Additionally, this study aimed to use a novel data pooling approach to combine data collected at 3 different sites via meta-analytical techniques that allow exploration of heterogeneity., Design: Multi-site case-control study., Methods: Three independent studies with similar protocols were conducted by separate research groups. Each study-site evaluated left/right judgement performance for images of feet and hands using Recognise© software and compared performance between people with AT and healthy controls. Results from each study-site were independently collated, then combined in a meta-analysis., Results: In total, 126 participants (40 unilateral, 22 bilateral AT cases, 61 controls) were included. There were no differences between AT cases and controls for hand image accuracy and reaction time. Contrary to the hypothesis, there were no differences in performance between those with AT and controls for foot image reaction time, however there were conflicting findings for foot accuracy, based on four separate analyses. There were no differences between the affected and unaffected sides in people with unilateral AT., Conclusions: Impairments in motor imagery performance for hands were not found in this study, and we found inconsistent results for foot accuracy. This contrasts to studies in persistent pain of limbs, face and knee osteoarthritis, and suggests that differences in pathoetiology or patient demographics may uniquely influence proprioceptive representation., (© The Author(s) 2021.

Objective: The aim of this review was to investigate if exercise induced hypoalgesia (EIH) occurs following isometric muscle contraction in people with local musculoskeletal symptoms., Design: Systematic review., Data Sources: MEDLINE, EMBASE, CINAHL & SportDiscus electronic databases were searched (inception to April 2020)., Eligibility Criteria: Two authors independently evaluated eligibility. Randomised controlled and crossover (repeated measures) trials that measured the effects of isometric exercise in participants with localised musculoskeletal pain during, and up to 2 hours after isometric exercise were included. Other inclusion criteria included comparison to another intervention, or comparison to healthy controls. Primary outcomes were experimentally induced pain thresholds and secondary outcomes included measures of pain sensitivity from clinical testing., Results: 13 studies with data from 346 participants were included for narrative synthesis. EIH was reported in some upper and lower limb studies but there were no consistent data to show isometric exercises were superior to comparison interventions., Conclusion: There was no consistent evidence for EIH following isometric exercise in people with musculoskeletal pain. These findings are different to those reported in asymptomatic populations (where EIH is consistently demonstrated) as well as conditions associated with widespread symptoms such as fibromyalgia (where isometric exercise may induce hyperalgesia). Although well tolerated when prescribed, isometric exercise did not induce EIH consistently for people seeking care for local musculoskeletal symptoms. The variance in the dose, location of contraction and intensity of protocols included in this review may explain the inconsistent findings. Further work is required to better understand endogenous analgesia in musculoskeletal pain conditions., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.

Objectives: Our primary objective was to report the presence of a conditioned pain modulation (CPM) effect in people with localised mid-portion Achilles tendinopathy and whether changes occur over a 12-week period. Our secondary objectives were to quantify the proportion of participants who present for tendinopathy research with previous interventions or co-morbidities, which may impact the CPM-effect and investigate modulating factors., Design: Prospective, observational cohort pilot study., Method: 215 participants presented for this Achilles tendinopathy research and were screened for inclusion with nine being included. Included participants had the CPM-effect (cold-pressor test) assessed using pressure pain thresholds at the Achilles tendon and quantified as absolute, relative and meaningful change at baseline and 12-week follow-up., Results: The most common reasons for exclusion were failure to meet a load-related diagnosis for Achilles tendinopathy (15.5%), presence of confounding other injury (14.1%) and previous injection therapy (13.6%). All participants had a meaningful CPM-effect at baseline and 12-week follow-up. The mean (SD, n) baseline relative CPM effect (reduction in PPTs) was -40.5 (32.7, 9) percent. Moderators of the CPM-effect as well as follow-up changes were not statistically analysed due to a small sample size., Conclusion: Based on these data, we would suggest that a homogenous population of patients with chronic, unilateral mid-portion Achilles tendinopathy and no other co-morbidities are likely to exhibit a meaningful CPM-effect. Impairments to endogenous analgesic mechanisms seen in people presenting with mid-portion Achilles tendinopathy may be due to other confounding variables., (Copyright © 2020 Sports Medicine Australia.

Background: Proximal hamstring tendinopathy (PHT) is a condition that occurs at all ages and levels of sporting participation. Presenting as localised lower buttock pain with tasks such as squatting and sitting, it can cause disability with sport, work and other activities of daily living. Recent research has investigated the effect of isometric exercise on pain and strength with a range of tendinopathies but there are no published studies on PHT. This protocol paper details a study investigating the effectiveness of isometric compared with isotonic exercise on pain and strength in people with PHT., Methods/design: The study is a prospective, cross-over randomised controlled trial (RCT). Twenty participants with PHT, recruited from the local community and sporting clubs will be recruited for the study. Participants will receive one session of isotonic hamstring strength exercises and one session of isometric hamstring exercise, with random allocation to the order of intervention.Primary outcomes will be hamstring strength measured with a dynamometer and pain with a functional task, assessed immediately following and 45 min after intervention. A secondary outcome will be pain with sitting assessed 24 hours after intervention.The effect of isotonic versus isometric exercise on hamstring pain and strength will be determined using a repeated measures linear mixed model. Further analyses will determine the proportion of patients with clinically important pain and strength improvements, using relative risks, χ 2 testing and number needed to treat., Discussion: This RCT protocol will investigate the effect of isometric compared with isotonic exercise for PHT., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Background: Achilles tendinopathy (AT) rehabilitation traditionally includes progressive tendon loading exercises. Recent evidence suggests a biopsychosocial approach that incorporates patient education on psychosocial factors and mechanisms of pain can reduce pain and disability in individuals with chronic pain. This is yet to be examined in individuals with AT., Objective: This study aims to compare the effects on movement-evoked pain and self-reported function of pain education as part of a biopsychosocial approach with pathoanatomical education for people with AT when combined with a progressive tendon loading exercise program., Methods: A single-site, randomized, double-blind, placebo-controlled clinical trial will be conducted in a university-based hospital in a laboratory setting and/or by telehealth. A total of 66 participants with chronic (>3 months) midportion or insertional AT will be randomized for the Tendinopathy Education of the Achilles (TEAch) study. All participants will complete progressive Achilles tendon loading exercises over 12 weeks and will be encouraged to continue with self-selected exercises as tolerated. All participants will complete 6-7 one-to-one sessions with a physical therapist to progress exercises in a standardized manner over 8 weeks. During the last 4 weeks of the intervention, participants will be encouraged to maintain their home exercise program. Participants will be randomized to 1 of 2 types of education (pain education or pathoanatomic), in addition to exercise. Pain education will focus on the biological and psychological mechanisms of pain within a biopsychosocial framing of AT. Pathoanatomic education will focus on biological processes within a more traditional biomedical framework of AT. Evaluation sessions will be completed at baseline and 8-week follow-up, and self-reported outcome measures will be completed at the 12-week follow-up. Both groups will complete progressive Achilles loading exercises in 4 phases throughout the 12 weeks and will be encouraged to continue with self-selected exercises as tolerated. Primary outcomes are movement-evoked pain during heel raises and self-reported function (patient-reported outcome measure information system-Physical Function). Secondary outcomes assess central nervous system nociceptive processing, psychological factors, motor function, and feasibility., Results: Institutional review board approval was obtained on April 15, 2019, and study funding began in July 2019. As of March 2020, we randomized 23 out of 66 participants. In September 2020, we screened 267 individuals, consented 68 participants, and randomized 51 participants. We anticipate completing the primary data analysis by March 2022., Conclusions: The TEAch study will evaluate the utility of pain education for those with AT and the effects of improved patient knowledge on pain, physical function, and clinical outcomes., International Registered Report Identifier (irrid): DERR1-10.2196/19111., (©Andrew A Post, Ebonie K Rio, Kathleen A Sluka, G Lorimer Moseley, Emine O Bayman, Mederic M Hall, Cesar de Cesar Netto, Jason M Wilken, Jessica F Danielson, Ruth Chimenti.

We aimed to establish consensus for reporting recommendations relating to participant characteristics in tendon research. A scoping literature review of tendinopathy studies (Achilles, patellar, hamstring, gluteal and elbow) was followed by an online survey and face-to-face consensus meeting with expert healthcare professionals (HCPs) at the International Scientific Tendon Symposium, Groningen 2018. We reviewed 263 papers to form statements for consensus and invited 30 HCPs from different disciplines and geographical locations; 28 completed the survey and 15 attended the meeting. There was consensus that the following data should be reported for cases and controls: sex, age, standing height, body mass, history of tendinopathy, whether imaging was used to confirm pathology, loading tests, pain location, symptom duration and severity, level of disability, comorbidities, physical activity level, recruitment source and strategies, and medication use history. Standardised reporting of participant characteristics aims to benefit patients and clinicians by guiding researchers in the conduct of their studies. We provide free resources to facilitate researchers adopting our recommendations., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Background: The absence of any agreed-upon tendon health-related domains hampers advances in clinical tendinopathy research. This void means that researchers report a very wide range of outcome measures inconsistently. As a result, substantial synthesis/meta-analysis of tendon research findings is almost futile despite researchers publishing busily. We aimed to determine options for, and then define, core health-related domains for tendinopathy., Methods: We conducted a Delphi study of healthcare professionals (HCP) and patients in a three-stage process. In stage 1, we extracted candidate domains from clinical trial reports and developed an online survey. Survey items took the form: 'The ' candidate domain' is important enough to be included as a core health-related domain of tendinopathy'; response options were: agree, disagree, or unsure. In stage 2, we administered the online survey and reported the findings. Stage 3 consisted of discussions of the findings of the survey at the ICON (International Scientific Tendinopathy Symposium Consensus) meeting. We set 70% participant agreement as the level required for a domain to be considered 'core'; similarly, 70% agreement was required for a domain to be relegated to 'not core' (see Results next)., Results: Twenty-eight HCP (92% of whom had >10 years of tendinopathy experience, 71% consulted >10 cases per month) and 32 patients completed the online survey. Fifteen HCP and two patients attended the consensus meeting. Of an original set of 24 candidate domains, the ICON group deemed nine domains to be core. These were: (1) patient rating of condition, (2) participation in life activities (day to day, work, sport), (3) pain on activity/loading, (4) function, (5) psychological factors, (6) physical function capacity, (7) disability, (8) quality of life and (9) pain over a specified time. Two of these (2, 6) were an amalgamation of five candidate domains. We agreed that seven other candidate domains were not core domains: range of motion, pain on clinician applied test, clinical examination, palpation, drop out, sensory modality pain and pain without other specification. We were undecided on the other five candidate domains of physical activity, structure, medication use, adverse effects and economic impact., Conclusion: Nine core domains for tendon research should guide reporting of outcomes in clinical trials. Further research should determine the best outcome measures for each specific tendinopathy (ie, core outcome sets)., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Objective: To assess the effectiveness of heavy eccentric calf training (HECT) in comparison with natural history, traditional physiotherapy, sham interventions or other exercise interventions for improvements in pain and function in mid-portion Achilles tendinopathy., Design: A systematic review and meta-analysis were conducted as per the PRISMA guidelines., Data Sources: PUBMED, CINAHL (Ovid) and CINAHL (EBSCO) were searched from inception until 24 September 2018., Eligibility Criteria: Randomised controlled trials comparing HECT to natural history, sham exercise, traditional physiotherapy and other exercise interventions were included. Primary outcome assessing pain and function was the Victorian Institute of Sports Assessment-Achilles., Results: Seven studies met the inclusion criteria. This review suggests HECT may be superior to both natural history, mean difference (MD) (95% CI) of 20.6 (11.7 to 29.5, one study) and traditional physiotherapy, MD (95% CI) of 17.70 (3.75 to 31.66, two studies). Following removal of one study, at high risk of bias, due to pre-planned sensitivity analysis, this review suggests HECT may be inferior to other exercise interventions, MD (95% CI) of -5.65 (-10.51 to -0.79, three studies). However, this difference is unlikely to be clinically significant., Conclusion: Current evidence suggests that HECT may be superior to natural history and traditional physiotherapy while HECT may be inferior to other exercise interventions. However, due to methodological limitations, small sample size and a lack of data we are unable to be confident in the results of the estimate of the effect, as the true effect is likely to be substantially different., Systematic Review Registry: PROSPERO registration number: CRD4201804493 PROTOCOL REFERENCE: This protocol has been published open access: Murphy M, Travers MJ, Gibson, W.

Objective: Pain pressure thresholds (PPT) are used to study peripheral and central pain processing. In the tendon, pathological changes may exist without pain. This pilot study aimed to compare PPT between individuals with normal tendons and asymptomatic tendon pathology, and between individuals with and without a history of tendon pain., Methods: The patellar, Achilles, and supraspinatus tendons of 128 asymptomatic participants were examined with ultrasound. Global PPT average was determined using a digital algometer at the patellar tendon, quadriceps muscle, L3 spinous process, and deltoid muscle insertion. Participants were separated into three groups: (1) healthy control group (no pathology, no history of pain), (2) tendon pathology at any site without a history of pain, (3) history of tendon pain anywhere., Results: There were 92 controls, seven with asymptomatic pathology and 29 with a history of tendon pain. Asymptomatic tendon pathology at any site (without a history of pain) was associated with globally increased PPTs compared with controls (P < 0.001, pathology N = 7, N = 92 controls). Matched pair analysis remained significant (P < 0.004). A history of tendon pain was associated with globally increased PPTs compared with the control group (P = 0.026). Matched pair analysis was not significant (P = 0.122)., Conclusions: Asymptomatic tendon pathology is associated with higher PPTs. These findings point toward central nervous system adaptations but in a novel way-central desensitization. This challenges the validity of conclusions drawn from PPT studies that do not verify normal structure in the control group; artificial inflation of control group data may incorrectly indicate decreased PPTs in the comparison group.
