Plain English Summary
Background and study aims
Subacromial impingement syndrome (SIS) is a condition that involves pain and weakness in the shoulder muscle. It is the most common cause of shoulder problems, affecting 1 in 3 adults. It is usually treated with a combination of exercises and medications including corticosteroids (which reduce inflammation (swelling)). Exercises meant to treat the SIS are usually standard for everyone and not customised for each patient and it would be interesting to see whether personalised exercises work better. We also want to find out whether using ultrasound (a scan that uses soundwaves to create an image of the inside of the body on a screen) can improve the accuracy of corticosteroid injections. There is a lack of evidence on the impact of exercise and corticosteroid injection for treating SIS. The aim of this study is to find out if corticosteroid injections in combination with individualised exercise are the most effective treatment for SIS.
Who can participate?
Adults with a diagnosis of SIS.
What does the study involve?
Participants are randomly allocated to one of four treatment groups.
Group one participants take part in an individualised exercise program run by a physiotherapist and receive corticosteroid injections guided by ultrasound. This involves using an ultrasound probe to show the area in question so that the injection can be given accurately.
Group two participants receive an information sheet with advice about exercises and receive an injection guided by an ultrasound.
Group three participants take part in an individualised exercise program run by a physiotherapist and have an injection which is not guided by ultrasound.
Group four participants receive an information sheet with advice about exercises and their injection is unguided.
Participants complete a number of questionnaires in order to assess their shoulder pain at the start of the study, 6 weeks, 6 months and 12 months post treatment.
What are the possible benefits and risks of participating?
Participants may experience pain relief or improvement to their shoulder symptoms. There are very few risks with steroid injections and participants will be given information on how to manage risks. Due to the exercise treatment, there is risk of temporary soreness in the shoulder.
Where is the study run from?
Primary Care Sciences Research Centre (lead centre) and two musculoskeletal Clinical Assessment and Treatment Services in Staffordshire (UK)
When is the study starting and how long is it expected to run for?
March 2011 to March 2014

Condition
Topic: Primary Care Research Network for England, Musculoskeletal; Subtopic: Not Assigned, Musculoskeletal (all Subtopics); Disease: Musculoskeletal, All Diseases
Intervention
Patients who provide written informed consent for trial participation will be randomised to one of four treatment groups, namely:
1. Ultrasound-guided corticosteroid injection, with physiotherapist-led individualised, supervised and progressed exercise
2. Ultrasound-guided corticosteroid injection, with an advice and exercise leaflet
3. Unguided (blind) corticosteroid injection, with physiotherapist-led individualised, supervised and progressed exercise
4. Unguided (blind) corticosteroid injection, with an advice and exercise leaflet.
The trial is organised and sponsored by the Arthritis Research UK Primary Care Centre, at Keele University, and is funded by the National Institute for Health Research: Research for Patient Benefit Programme. We plan to recruit 252 patients from within North and South Staffordshire to this trial.
Ultrasound-guided subacromial, Interface clinicians within the musculoskeletal interface service shoulder clinics will deliver ultrasound (US)-guided subacromial injection using a standard technique. Ultrasound examinations will be performed using the LOGIQe system with a 12MHz transducer.

Eligibility
Participant inclusion criteria
1. 18 years and over, referred to interface service shoulder clinics with shoulder problems
2. No history of significant shoulder trauma, for example, fracture or full thickness cuff tear
3. A clinical diagnosis of subacromial impingement syndrome (SIS) i.e. pain in deltoid insertion area, positive Neer and HawkinsKennedy tests, pain on shoulder abduction
Accurate diagnosis of SIS is challenging, but a combination of the patients history and response to Neer and HawkinsKennedy tests (to rule SIS out with a negative test) and pain on shoulder abduction (to rule SIS in with a positive test) provides optimal sensitivity and specificity. Patients will not be required to undergo diagnostic imaging (eg MRI) to reflect current practice where treatment choices are informed by clinical findings;
