The absence of agreed methods to diagnose Achilles tendinopathy impedes research and clinical practice. This gap results in heterogeneous and/or poorly described study samples, making it challenging to apply findings in clinical practice. The aim of this Delphi study was to define consensus on (1) diagnostic domains; (2) differential diagnoses; and...

Introduction Acute Achilles Tendon Ruptures (ATR) cause lasting muscular deficits and impair function and quality of life. This study aimed to understand recovery post rupture by examining tendon structure using ultrasound tissue characterisation (UTC), isometric plantarflexor strength, physical activity and patient reported outcomes (PROM). Metho...

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 se...

OBJECTIVE: To identify which psychological and psychosocial constructs to include in a core outcome set to guide future clinical trials in the tendinopathy field. DESIGN: Modified International Delphi study. METHODS: In 3 online Delphi rounds, we presented 35 psychological and psychosocial constructs to an international panel of 38 clinician/resear...

Introduction: Exercise therapy is usually prescribed as first-line treatment for lower limb tendinopathies. The multitude of exercise- and non-exercise-based management options can be overwhelming for the treating sports professional and patient alike. We chose to investigate the comparative effectiveness of exercise therapy with or without adjunc...

Tendinopathy describes a spectrum of changes that occur in damaged tendons, leading to pain and reduced function that remains extremely challenging for all clinicians. There is an increasing awareness of the influence that psychological and psychosocial components, such as self-efficacy and fear-avoidance, have on rehabilitation outcomes in musculo...

Objective: To identify and describe the psychological and psychosocial constructs and outcome measures used in tendinopathy research. Design: Scoping review. Literature search: We searched the PubMed, EMBASE, Scopus, Web of Science, PEDro, CINAHL, and APA PsychNet databases on July 10, 2021, for all published studies of tendinopathy population...

Background Nine core domains for tendinopathy have been identified. For Achilles tendinopathy there is large variation in outcome measures used, and how these fit into the core domains has not been investigated.Objective To identify all available outcome measures outcome measures used to assess the clinical phenotype of Achilles tendinopathy in pro...

Background There is currently limited evidence identifying the mechanism of Achilles tendon rupture (ATR). Identification of this mechanism would aid rehabilitation and injury prevention strategies. Objective Determine the movement pattern (mechanism of injury) for ATRs. Design A systematic video search was completed of all publicly available vid...

Background . Achilles tendinopathy (AT) is common, and can be traumatic or insidious in onset and short-lasting or persistent in nature. Factors influencing the experience of pain are poorly understood; little is known about mechanisms driving pain and the response (or lack of) to rehabilitation. Despite this, there is a growing body of evidence su...

BACKGROUND: Combined physical and psychological programmes (CPPP) are recommended for people with disabling low back pain (LBP). Cognitive Functional Therapy (CFT) is a physiotherapist-led low intensity CPPP with positive effects in previous studies. The clinical and cost effectiveness of CFT has not previously been evaluated in a randomised contro...

Background Greater Trochanteric Pain syndrome (GTPS) is a condition causing lateral hip pain, which can be both persistent and debilitating. Data suggests that NHS patients with GTPS often have complex presentations with greater risk of developing persistent pain. No research to date has looked to understand the lived experience of patients with GT...

Background: Persistent strength deficits secondary to Achilles tendinopathy (AT) have been postulated to account for difficulty engaging in tendon-loading movements, such as running and jumping, and may contribute to the increased risk of recurrence. To date, little consensus exists on the presence of strength deficits in AT. Consequently, researc...

Purpose: Greater trochanteric pain syndrome (GTPS) is a debilitating condition causing lateral hip pain. A recent randomized controlled trial (LEAP) demonstrated that exercise interventions for GTPS provided superior outcomes, compared with corticosteroid injection and wait-and-see approaches. However, participants were not patients seeking care a...

Purpose: Greater Trochanteric Pain syndrome (GTPS) is a debilitating condition causing lateral hip pain. It affects up to 23.5% of women and 8% of men between 50 and 75 years old. Sufferers report comparable quality of life and functional performance to patients with end stage osteoarthritis of the hip. Understanding of optimal management strategie...

Objectives: Determine how the strength and endurance of the plantar flexors are affected by Achilles tendinopathy and whether one muscle is more affected than another. Design: Case control study. Setting: University Laboratory. Participants: 39 Runners with mid-portion Achilles tendinopathy and 38 healthy runners participated in this study....

PurposeThe purpose of this study was to explore the immediate effects of heavy isometric plantar flexor exercise on sensory output (pain during a functional task and mechanical pain sensitivity) and motor output (plantar flexor torque) in individuals with Achilles tendinopathy. Methods Sixteen subjects with Achilles tendinopathy participated in the...

Tendinopathy has a multifactorial etiology that is not well understood. Risk factors are often separated into extrinsic (those acting on the body) and intrinsic groups (those acting from within the body). In this narrative review, we will separate potential risk factors into 1) load-related (extrinsic); 2) biomechanical factors (intrinsic); and 3)...

Background Transient changes in Achilles tendon structure are known to occur post exercise, it is unknown whether completing an ironman affects tendon structure. Objective Assess the effect of an ironman on Achilles tendon structure. Design Case study of a subject completing an ironman triathlon. The study utilised Ultrasound tissue characterizat...

c testing is often completed in knee extension to assess force production from both Gastrocnemius and Soleus but testing can also be completed in higher degrees of knee flexion to inhibit Gastrocnemius biasing testing to Soleus in relative isolation. The reliability of these methods of testing has not been robustly determined. METHODS: Thirty-seven...

ABSTRACT Background and Purpose: Achilles tendinopathy can be a debilitating chronic condition for both active and inactive individuals. The identification of risk facors is important both in preventing but also treating tendinopathy, many factors have been proposed but there is a lack of primary epidemiological data. The purpose of this study was...

Unlabelled: Achilles Tendinopathy is a complex problem, with the most common conservative treatment being eccentric exercises. Despite multiple studies assessing this treatment regime little is known about the mechanism of effect. This lack of understanding may be hindering therapeutic care and preventing optimal rehabilitation. Of the mechanisms...

Introduction Our previous work has shown a clear clinical and statistical significant difference in Plantarflexor power between healthy controls and participants with Achilles tendinopathy (AT), p ≤ 0.004 for all test positions and speeds. This data showed that the Soleus is responsible for the majority of the observed power deficits. Aim -Determin...

Introduction Muscle power of the Plantarflexors has been shown to be a prospective risk factor for Achilles Tendinopathy (AT).1 Several studies have shown associations between Achilles tendinopathy and Plantarflexor power, but little thought has been given to how the individual muscles of the Triceps Surae are affected. Aim – Compare the Triceps Su...

Introduction Plantar-flexor power below 50 Nm has been shown to be predictive of Achilles tendinopathy in army recruits [Mahieu, 2006]. It appears that muscle weakness may expose the tendon to greater load. As such, eccentric regimes have been proposed as an effective prophylactic intervention [Fredberg, 2008]. However, little is known about how a...
