Control of the lumbar neutral zone decreases low back pain and improves self-evaluated work ability : a 12-month randomized controlled study . STUDY DESIGN A randomized controlled study with 12 months intervention . OBJECTIVE To study the effectiveness of a training intervention with emphases on the control of lumbar neutral zone ( NZ ) and behavior modeling as secondary prevention of low back pain ( LBP ) and disability . SUMMARY OF BACKGROUND DATA Improving the control of lumbar NZ and enhancing muscle activation patterns ensuring spinal stability have been proposed as means for secondary prevention of LBP and disability . In addition , cognitive behavior interventions have been shown to lower the risk of recurrence of LBP and long-term disability . METHODS Middle-aged working men with recent LBP but without severe disability were randomly allocated to either a training ( TG , n = 52 ) or control group ( CG , n = 54 ) . The aim was to exercise twice a week for 12 months , once guided and once independently . The outcome measures were the changes in intensity of LBP , disability , self-evaluated future work ability , and neuromuscular fitness . RESULTS The intensity of LBP decreased significantly more ( 39 % ) in the TG than in CG at 12 months . The proportion of subjects with negative expectations about their future work ability decreased in both groups at 6 and 12 months ; however , the proportion was significantly bigger in TG compared with CG ( P = 0.028 ) . There effects on disability indexes and fitness were not statistically significant . CONCLUSIONS Controlling lumbar NZ is a specific form of exercise and daily self-care with potential for prevention of recurrent nonspecific LBP and disability among middle aged working men .
