Plain English Summary
Background and study aims
Low back pain (LBP) is the leading cause of disability worldwide. Over 70% of people will suffer with LBP in their lifetime, and the chance of having the most serious forms of LBP increases with age. It is associated with loss of mobility and falls in older people leading to loss of independence and frailty, however, this is the time in life when GPs and patients are least likely to prioritise treatment for LBP. In later life people are much more likely to have other health conditions which they think are more important than LBP. Some older people just grin and bear the pain, accepting it as part of ageing. Although there is a large body of research in LBP, this has focused almost exclusively on younger people. Hence there is little guidance appropriate to older people. Lumbar spinal stenosis is a common back condition in older adults where the spinal cord is compressed due to narrowing of the spinal canal. This leads to a range of symptoms including pain, tingling, numbness or heaviness spreading from the back into one or both legs, together known as neurogenic claudication. Neurogenic claudication is a common symptom of lumbar spinal stenosis (narrowing of the spine leading to compression of the spinal cord), a leading cause of LBP in the aging population. Neurogenic claudication affects a person’s ability to walk and stand which impacts on their ability to remain independent. There is little research to help us know what type of physiotherapy is best for people with neurogenic claudication. The aim of this study is to compare the effectiveness of two different approaches to physiotherapy which have been designed to help older adults with neurogenic claudication to stay mobile and remain independent.
Who can participate?
Adults aged 65 years or over who live at home and report symptoms of neurogenic claudication.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group take part in a 12-week group physiotherapy programme. This involves weekly hour-and-a-half long sessions of exercises and group discussions about ways to manage symptoms and be more physically active. Those in the second group receive an individual session with a physiotherapist in which they are provided with information about exercises and how best to manage their symptoms. These participants can receive two follow up sessions if required. Participants in both groups complete a number of questionnaires and physical assessments at the start of the study and again 6, 12 and 24 months later in order to find out if their symptoms have improved.
What are the possible benefits and risks of participating?
Participants may benefit from an improvement to their back and leg symptoms because of the advice, information and exercises given to them by the physiotherapist. There is a risk of muscle soreness after completing some of the exercises however this is normal and the physiotherapist will provide advice on how to manage this. Some participants may feel uncomfortable answering certain questions about their health during the study, but they will be advised that they are not obliged to answer any questions they are not comfortable with.

Condition
Neurogenic claudication, Spinal stenosis
Intervention
Participants are randomly allocated to one of two groups.
Intervention group: Participants take part in a 12-week group physiotherapy programme comprising of a progressing exercise programme underpinned by cognitive behavioural strategies to promote engagement and adherence with the programme. Each class lasts for 1.5 hours and will involve exercises and group discussions about ways to manage symptoms and be more physically active.
Control group: Participants receive one individual session to provide information about exercise and self-management with two optional follow up sessions if required.
After treatment, participants will be invited to two follow-up appointments with the researcher (6 and 12 months after they join the study). They will also receive a questionnaire in the post 2 years after joining the study which we will ask them to complete and return to the BOOST Trial Team.
