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 .
Characterizing the course of low back pain: a latent class analysis.
Underst and ing the course of back pain is important for clinicians and research ers , but analyses of longitudinal data from multiple time points are lacking . A prospect i ve cohort study of consecutive back pain consulters from five general practice s in the United Kingdom was carried out between 2001 and 2003 to identify groups defined by their pain pathways . Patients were sent monthly question naires for a year . Longitudinal latent class analysis was performed by using pain intensity scores for 342 consulters . Analysis yielded four clusters representing different pathways of back pain . Cluster 1 ( " persistent mild " ; n = 122 ) patients had stable , low levels of pain . Patients in cluster 2 ( " recovering " ; n = 104 ) started with mild pain , progressing quickly to no pain . Cluster 3 ( " severe chronic " ; n = 71 ) patients had permanently high pain . For patients in cluster 4 ( " fluctuating " ; n = 45 ) , pain varied between mild and high levels . Distinctive patterns for each cluster were maintained throughout follow-up . Clusters showed statistically significant differences in disability , psychological status , and work absence ( p < 0.001 ) . This is the first time , to the authors ' knowledge , that latent class analysis has been applied to longitudinal data on back pain patients . Identification of four distinct groups of patients improves underst and ing of the course of back pain and may provide a basis of classification for intervention
