Does the occupational activity level affect the quality of life of patients treated with epidural steroid injections for lumbar disc herniations?
METHODS
Prospective cohort study.


OBJECTIVE
To determine whether there was any change in the quality of life of patients in sedentary/non sedentary occupations treated with epidural steroid injection for lumbar disc herniations using the 8 components of the SF 36 questionnaire.Overview of Literature: No previously done similar study published.


BACKGROUND
No previously done similar study published.


METHODS
Ninety patients comprising sedentary and non sedentary occupations with lumbar disc herniations on magnetic resonance imaging who were treated with epidural steroid injection at St. John's Hospital Bangalore who met the Spinal Outcomes Research Trial eligibility criteria from April 2009 to May 2010.


RESULTS
Of the 90 patients evaluated 44 were of Sedentary and 46 were of non sedentary activity levels, At 6 months primary outcomes physical functioning (p = 0.573, in difference between sedentary and non sedentary, improvement p = 0.001) energy/fatigue (difference between the two p = 0.917, improvement p = 0.001), emotional well being (difference p = 0.912, improvement, p = 0.001), social functioning (difference p = 0.523, improvement p = 0.232), pain (difference p = 0.535, improvement p = 0.001), general health (difference p = 0.738, improvement p < 0.001).


CONCLUSIONS
There was a statistically significant improvement in patients of both the sedentary and non sedentary groups p < 0.001 in all components of the SF36 in both sedentary and non sedentary patients except social functioning where the improvement was not statistically significant, and there was no significant difference between non sedentary and sedentary populations over time.
