Evidence Summary
A large body of good quality interventional data shows an improvement in quality of life as measured by outcome scores.
Quality of Evidence
Grade B – moderate quality. Evidence comes from randomised controlled trials
Strength of recommendation
Grade 1 – strong recommendation. Clinical and patient consensus is that physical activity can improve quality of life scores. On the basis of the existing evidence, clinical opinion is that all or most patients will be best served by following this piece of evidence. The vast majority of patients would choose to follow this evidence when given the choice
Conclusion
Strong recommendations can be applied to most patients in most circumstances and should be followed unless there are compelling reasons to do otherwise
