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 Effectiveness of High-Intensity Versus Low-Intensity Back Schools in an Occupational Setting: A Pragmatic Randomized Controlled Trial
Study Design . R and omized controlled trial . Objectives . To compare high- and low-intensity back schools with usual care in occupational health care . Summary of Background Data . The content and intensity of back schools vary widely and the method ologic quality of r and omized controlled trials is generally weak . Until now , no back school has proven to be superior for workers sick-listed because of subacute nonspecific low back pain . Methods . Workers ( n = 299 ) sick-listed for a period of 3 to 6 weeks because of nonspecific low back pain were recruited by the occupational physician and r and omly assigned to a high-intensity back school , a low-intensity back school , or care as usual . Outcome measures were days until return to work , total days of sick-leave , pain , functional status , kinesiophobia , and perceived recovery and were assessed at baseline and at 3 and 6 months of follow-up . Principal analyses were performed according to the intention-to-treat principle . Results . We r and omly allocated 299 workers . Workers in the low-intensity back school returned to work faster compared with usual care and the high-intensity back school , with hazard ratios of 1.4 ( P = 0.06 ) and 1.3 ( P = 0.09 ) , respectively . The comparison between high-intensity back school and usual care result ed in a hazard ratio of 1.0 ( P = 0.83 ) . The median number of sick-leave days was 68 , 75 , and 85 in the low-intensity back school , usual care , and high-intensity back school , respectively . Beneficial effects on functional status and kinesiophobia were found at 3 months in favor of the low-intensity back school . No substantial differences on pain and perceived recovery were found between groups . Conclusions . The low-intensity back school was most effective in reducing work absence , functional disability , and kinesiophobia , and more workers in this group scored a higher perceived recovery during the 6-month follow-up
