That is , persons with acute or subacute LBP appear to vary in the levels of physical activity independent of their pain-related disability .
Persons with chronic LBP with high levels of disability are also likely to have low levels of physical activity .
Persons with acute or subacute back pain appear to vary in the levels of physical activity independent of disability .
Persons with chronic back pain with high levels of disability will likely have low levels of physical activity
It is often assumed that patients with pain-related disability due to low back pain ( LBP ) will have reduced physical activity levels , but recent studies have provided results that challenge this assumption .
The aim of our systematic review was to examine the relationship between  physical activity  and disability in LBP .
The course of chronic and recurrent low back pain in the general population
& NA ; Using latent class analysis ( LCA ) , a previous study on patients attending primary care identified four courses of low back pain ( LBP ) over the subsequent 6 months . To date , no studies have used longitudinal pain recordings to examine the “ natural ” course of recurrent and chronic LBP in a population ‐based sample of individuals . This study examines the course of LBP in the general population and elaborates on the stability and criterion‐related validity of the clusters derived . A r and om sample of 400 individuals reporting LBP in a population ‐based study was asked to complete a comprehensive question naire at the start and end of the year 's survey , and 52 weekly pain diaries in between . The latter were analyzed using LCA . 305 individuals returned more than 50 % of the diaries . Four clusters were identified ( severe persistent , moderate persistent , mild persistent , and fluctuating ) . The clusters differed significantly with regards to pain and disability . Assessment of cluster stability showed that a considerable proportion of patients in the “ fluctuating ” group changed their classification over time . Three of the four clusters describing the typical course of pain matched the clusters described previously for patients in primary care . Due to the population ‐based design , this study achieves , for the first time , a close insight into the “ natural ” course of chronic and recurrent low back pain , including individuals that did not necessarily visit the general practitioner . The findings will help to underst and better the nature of this pain in the general population
