Plain English Summary
Background and study aims
Tendinopathy (also known as tendinitis) is a condition that causes pain in a tendon that joins bone to your muscles. It is a relatively common soft tissue injury and affects people of all ages, both athletes and non-athletes. Tendinopathy is common and problematic if it does not resolve. The study aims to find out why it does not resolve, and what the predictors of recovery are. Data will be collected from a large number of participants they will be followed up for one year to determine causal relationships between how people present and how they recover. At present, prediction of outcome is restricted to single or limited variables and no clinically relevant prediction models exist for these pathologies. To best inform the model, we will also collect data from participants with different problems in the same anatomical area. The main data collection will be questionnaires, with a questionnaire battery at the start and then brief monthly follow-ups. We will also collect clinical, imaging and biomechanical data for subsets of participants.
Who can participate?
Aged 18 years and above, with tendinopathy (Achilles, gluteal, patellar, rotator cuff tendinopathy or plantar heel pain), and matched healthy controls
What does the study involve?
The main part of the study will be completing online questionnaires via SmartTrial, the baseline questionnaires take 25-30 minutes to complete. Participants will then receive follow up emails for 12 months, every four weeks for shoulder, hip, ankle and foot and every three weeks for knee group. Follow up surveys take 4-5 minutes to complete. An optional clinical assessment can be completed (participants opt-in or out whilst completing the online questionnaires.
What are the possible benefits and risks of participating?
Benefits: The benefits of the study would be to improve the implementation of research findings for predictors of tendinopathies into practice. Participants would play an active role in shaping this development by taking part in the study, meaning that future patients will be treated with an effective evidence-based protocol from the start leading to an optimum management of their condition. Individual participants also stand to gain a deeper understanding of their condition which may help them to manage their symptoms better.
Physical tests exacerbate existing symptoms:
In rare instances, clinical assessment process may cause pain, tightness or soreness or strain. Investigators will minimise the incidence of adverse events by recommending appropriate preparation and warm-up that will help prevent this. A physiotherapist will be present during the entire assessment process and will advise participants, in case of any injury possibility.
Clinical exam shows previously unrecognised pathology:
Clinical and US imaging may reveal previously undiagnosed pathology. This is likely with the clinical examinations when participants have not been previously assessed. Assessment will always be done by clinicians who can advise and refer as appropriate
Where is the study run from?
Queen Mary University of London in partnership with Barts Health NHS Trust, UK
When is the study starting and how long is it expected to run for?
December 2019 to June 2021
Who is funding the study?
1. Engineering and Physical Sciences Research Council, UK
2. National Institute for Health Research, UK

3T_the 10000 Tendons study: outcome prediction for 5 tendinopathies: an international cohort study
The study aim is to build a usable clinical model that predicts the outcome for tendinopathy. The objectives are to:
1. Variably phenotype and follow a large number of patients with tendinopathy
2. Compare prognostic factors with data from people with other problems in the same area and healthy controls
3. Construct regression and Bayesian probabilistic models to predict recovery.

Patient information sheet
Not available in web format; please use contact details to request a participant information sheet
Patients will be identified by clinicians at recruiting organisations and contact details sent, via a secure SmartTrial contact form to the researchers who will respond with a link to the correct database form for their problem area. They will then have as long as they require to peruse the PIS and complete the online ICF before carrying out the questionnaire battery.
The highest volume, lowest detail information set will include questionnaire data using an online Survey with the online SmartTrial electronic CRF from recruited patients. A pain drawing will be made using navigate pain. Data will include self-reported physical factors, psychosocial factors, health-related quality of life, condition-specific factors and activity level.
For people with shoulder pain, scapular dyskinesis will be examined via shoulder motion video recorded by participants. The video for scapular dyskinesis assessment will be collected via File Request system on Dropbox according to a filming guide.
The first survey takes just under 30 minutes to complete followed by very short monthly follow-ups of 1-2 minutes.
Entering the physical assessment and ultrasound imaging data is an optional extra depending on the choices made by the patient on the ICF. Medium volume, medium density data will further include clinical and imaging examination from 200 patients per tendon area, only of those with pathology, using clinical examination and ultrasound. Range of motion and muscle strength evaluation, palpation and other tests will be measured. All data entered on SmartTrial from clinical examination will have been performed as part of usual care.
For information only: The most detailed, low density data will include biomechanical testing of 60 people per tendon area comprising Kinetic and kinematic assessment using Force plate, surface EMG and motion tracking systems to measure ground reaction force, identify muscle activity and capture kinetic and kinematic features of joint moments, respectively. All data will be recorded within Coda-Motion Software system. This is covered by existing university ethics clearance and is not requests to be covered by this application.
Participants will be followed up for one year.
Once 50% of the data has been collected an interim analysis will be carried out to deign a retrospective model based on the data, to be tested prospectively with the second 50% of the data.
Analysis will be made for tendinopathy (all tendons), individual tendons, controls and for other conditions.
Primary outcome measure
Symptoms/change in pain is measured using the global rating of change every four weeks via questionnaires on SmartTrial (every three weeks for knee), for 12 months. Except for the control group who are asked if they have any new symptoms/pain
Secondary outcome measures
1. Symptoms/change in pain is measured using the patient acceptable symptom state (PASS) every four weeks via questionnaires on SmartTrial (every three weeks for knee), for 12 months. Except for the control group who are asked if they have any new symptoms/pain
2. Symptoms/change in pain is measured using the single assessment numeric evaluation (SANE) every four weeks via questionnaires on SmartTrial (every three weeks for knee), for 12 months. Except for the control group who are asked if they have any new symptoms/pain
