Background and study aims
Patients with back pain may or may not experience pain which spreads to their legs. Previous research has found that patients who have back and leg pain suffer more severe pain and disability, take longer to recover, and lose more time off work than those with back pain alone. However, it is not known if this is because of the leg pain or some other related factor(s).
One type of leg pain, called Nerve Root Pain, often spreads below the knee and means there is a problem with the nerves. Doctors think it is important to distinguish between patients who have back pain alone, those with back and leg pain, and those with back pain and nerve root pain. This is so that these groups can be assessed and treated appropriately.
The study aims to answer the following research questions: what are the characteristics and costs of patients with back and leg pain at the time they consult their GP and over the following 12 months, and which factors are associated with a worse outcome? Do patients with nerve root pain differ from those with no nerve root pain?
Who can participate?
Patients with lower leg and back pain.
What does the study involve?
Patients who consult their GP for back and leg pain will be referred to a community clinic for assessment by a physiotherapist and treatment according to their symptoms. Five hundred patients will be recruited to the study. Information about the characteristics (pain, disability, psychological factors, employment, other health conditions, health care use) of these patients will be collected on postal questionnaires at baseline (when they are enrolled in the study), and each month for the following year. Participants will also have a Magnetic Resonance Imaging (MRI) scan at baseline.
What are the possible benefits and risks of participating?
This study will inform better targeting of treatment to improve outcomes in patients with back and leg pain, which will be tested in future trials.
There are no risks to participants from taking part in this study.
Where is the study run from?
The study is taking place in North Staffordshire and Stoke-on-Trent (UK).
When is the study starting and how long is it expected to run for?
The study started in March 2011 and is expected to complete in December 2013.
Who is funding the study?
The National Institute for Health Research (NIHR), UK.
Who is the main contact?

| Study objectives | Patients with back pain may or may not experience pain which spreads to their legs. Previous research has found that patients who have back and leg pain suffer more severe pain and disability, take longer to recover, and lose more time off work than those with back pain alone. However, it is not known if this is because of the leg pain or some other related factors. One type of leg pain, called Nerve Root Pain, often spreads below the knee and means there is a problem with the nerves. Doctors think it is important to distinguish between patients who have back pain alone, those with back and leg pain, and those with back pain and nerve root pain. This is so that these groups can be assessed and treated appropriately. Research questions: 1. What are the characteristics and costs of patients with back and leg pain at the time they consult their GP and over the following 12 months, and which factors are associated with a worse outcome? 2. Do patients with nerve root pain differ from those with no nerve root pain? 3. Patients who consult their GP for back and leg pain will be referred to a community clinic for assessment by a physiotherapist and treatment according to their symptoms. Five hundred patients will be recruited to the study. Information about the characteristics (pain, disability, psychological factors, employment, other health conditions, health care use) of these patients will be collected on postal questionnaires at baseline, and during one year of followup. Participants will also have an MRI scan at baseline. This study will inform better targeting of treatment to improve outcomes in patients with back and leg pain, which will be tested in future trials. |

| Health condition(s) or problem(s) studied | Musculoskeletal diseases |
| Intervention | 1. Patients receive a standardised physiotherapy assessment for back and leg pain and are treated by a study physiotherapist according to need 2. Clinical management will follow agreed care pathways, based on current best clinical evidence, practice guidelines and local services and resources 3. Allocation to one of 3 care pathways will take into account the patients diagnosis, severity of symptoms, response to previous treatment, and patient preferences |
