COmbining Brief Interventions for Modifiable Health Behaviours withIN a Physiotherapy Consultation for pEople With a Rotator Cuff Disorder: Development and Testing in a Single-arm Feasibility Study

The COMBINED study is looking at how current treatments can be improved for people with shoulder pain, who have been diagnosed with a rotator cuff (RC) disorder. The RC is a group of muscles and tendons which move and stabilise the shoulder joint, and problems with these muscles and tendons can result in pain and difficulty doing everyday tasks.

Current treatments for RC disorders offer only small to moderate benefits and long-term outcomes can be poor. Lifestyle factors, including smoking, being overweight and physical inactivity are associated with the onset and persistence of RC disorders. These factors are linked to modifiable health behaviours that if patients are supported to change, might help improve their shoulder pain. Despite this evidence, physiotherapists do not routinely integrate health behaviour change approaches as part of the management for RC disorders.

The investigators have designed and tested a new complex intervention, The COMBINED approach, that aims to help patients improve their shoulder pain by identifying and assessing the lifestyle factors associated with the onset and persistence of a RC disorder and, where appropriate, the delivery of a brief behaviour change intervention to address these as part of a management plan, supported by a physiotherapist. The investigators have also developed an implementation toolkit to enable and support physiotherapists to effectively deliver this approach in clinical practice. This has been tested and refined in a small usability study, which has led to an optimised version of The COMBINED approach. The investigators would like to find out if this treatment approach can now be delivered within the NHS and to improve this further before testing it in a definitive randomised controlled trial. The overall aim is to provide better care for people with a RC disorder.

This will be a non-randomised feasibility study with qualitative interviews. The study will be conducted in physiotherapy musculoskeletal services across four NHS sites and expected to last 4-6 months. Chartered physiotherapists working at one of the musculoskeletal physiotherapy services, and patients diagnosed with a RC disorder will be eligible to take part.

Physiotherapist participants would be expected to attend a training workshop, deliver the new treatment approach to patients and complete a survey. Patient participants would be asked to attend up to two treatment sessions for their shoulder pain (~60 mins each) with a qualified physiotherapist. During this treatment session they will be asked some questions about their shoulder pain and other things that could be influencing their shoulder pain, such as if they smoke, their weight and how active they are. Where applicable, the physiotherapist may also measure their height and weight during the consultation. The participants will have an examination of their shoulder. Different treatment options will then be discussed. This will be very similar to what participants would expect in a normal physiotherapy appointment. The treatment sessions will be audio-recorded (with consent), for the purpose of checking what information and treatment was delivered by the physiotherapist in the session. The lead researcher may also request (with consent), to observe one of the treatment sessions. The purpose of this is to identify ways to improve how physiotherapists deliver the new treatment approach.
