Background and study aims
Carpal Tunnel Syndrome (CTS) is a common condition in which a nerve (known as the median nerve) is squeezed where it passes through the wrist. It can cause pain or aching, tingling or numbness in the affected hand. It may disturb sleep, or affect ability to do day to day things. There have been several studies into the best treatment of patients with severe symptoms of CTS who are referred to a hospital for treatment. However, little is known about the best treatments for patients with mild to moderate symptoms who visit their GP but do not require hospital treatment. This study aims to find out whether a single steroid injection is effective in treating CTS symptoms when compared with a night splint in people suffering with mild to moderate carpal tunnel syndrome.

Who can participate?
Patients aged 18 and over who have been diagnosed with mild to moderate CTS which has been present for at least 6 weeks

What does the study involve?
Each participant is randomly allocated to receive either a single steroid injection or a splint, and is asked to complete up to five questionnaires over 2 years. The steroid is a drug called DepoMedrone and is already widely used to treat CTS. The splint is made of elastic and has an aluminium bar which sits on the palm of the hand. In this study, the splint will be worn at night for 6 weeks. We study the effects of these two treatments over 6 weeks and at 6 months. We also look at whether these 6 weeks of treatment are effective 1 year and 2 years later.

What are the possible benefits and risks of participating?
Not provided at time of registration

Where is the study run from?
The study will take place in up to 50 GP practices and hospital clinics across the UK

When is the study starting and how long is it expected to run for?
April 2014 to September 2017

InterventionEach participant will receive either a single steroid injection or a splint. The steroid is a drug called “DepoMedrone 20mg.” This drug is already widely used to treat CTS. In this study, one injection will be given. The splint is made of elastic and has an aluminium bar which sits on the palm of the hand. In this study, the splint will be worn at night for 6 weeks. Each participant will be asked to complete up to 5 questionnaires over 2 years. We will study the effects of these 2 treatments over 6 weeks and at 6 months. Subject to further funding, the Study will also look at whether these 6 weeks of treatment are effective 1 year and 2 years later.
