Some occupations are more prone to low back pain (LBP) due to their static work postures and work place design. Multidisciplinary pain programs have shown their effectiveness in the management of LBP in general population but which treatment and which segment of the population will be benefited more was not investigated yet. This study determines the effect of two treatment protocols on five occupationally subgrouped male LBP patients.


A total of 102 occupational male, 20-40 yrs of age, with sub-acute or chronic nonspecific LBP were randomized and treated either with conventional treatment a combination of two electrotherapy (ultrasound and short wave diathermy) and one exercise therapy (lumbar strengthening exercises) or dynamic muscular stabilization techniques (DMST) an active approach of stabilizing training. At the end of the treatment, subjects of both the groups were further stratified in five subgroups on the basis of their occupation. The pain was the primary outcome measure while physical strength [back pressure changes (BPC) and abdominal pressure changes (APC)] the secondary.


The Pain, BPC and APC of all subgroups improved significantly (P < 0.01) in the both treatments but more in DMST. For each variable, improvement in subgroups differed within and between the treatments. Overall improvement in all assessed variables were evident on Desk workers followed by Shop keepers the most while BPC of Movement job, APC of Others and Pain of Sedentary and Shop keepers improved the least.


Study concluded that for the management of occupational LBP, DMST is more effective than conventional treatment. The Pain of Sedentary and Shopkeepers and physical strength of Movement job and Others may need more clinical attention. Findings of this study may be helpful in the management of occupational LBP.
