What is the CLEAT study


CLEAT is a research study seeking to recruit 256 people with hip arthritis who have been referred to the physiotherapy department at University Hospitals Dorset NHS Foundation Trust. 

The purpose of the study is to find out whether people who receive a group 8-week education and static cycling treatment (The CHAIN programme) have an improvement in their hip function and less pain than those patients who receive usual physiotherapy treatment within the NHS.

It is delivered in Bournemouth, Dorset (UK) by University Hospitals Dorset and involves researchers from Bournemouth University.

Half of patients on the study will receive routine physiotherapy treatment that is available through the NHS. The other half will receive group education and static cycling sessions (The CHAIN programme) for one hour per week over eight weeks at the Littledown Centre in Bournemouth.

Whether you receive standard physiotherapy treatment or the weekly static cycling and education sessions will be decided at random, similar to the toss of a coin.  Your levels of hip function and pain will be assessed at the Orthopaedic Research Institute, Bournemouth University before you start your treatment and again once your treatment has finished so that we can record any changes. We will also send you some further questionnaires to complete three months after you have finished treatment.

The results of this study will be based on your opinions about changes in pain, ability to perform everyday activities and quality of life; and from information collected by the research team at your assessments. 

What are the benefits of taking part in the study?

This research aims to improve patient care. By taking part in this research, you will help to guide treatment for future patients. In addition to your treatment, you will also benefit from a baseline and follow up assessment with a physiotherapist, where you will be able to ask further questions and measure the outcome of your treatment.

Both treatment arms have proven successful in managing the symptoms of patients with hip osteoarthritis.

The findings will be published in relevant scientific journals and presented at conferences and meetings. No personal identifiable data will be disclosed in any publication.
