IntroductionLow back pain (LBP) are prevalent in prehospital emergency (PE) technicians. This study aimed to investigate effect of chamomile oil on the intensity of LBP in PE technicians.MethodsIn this three-blind randomized clinical trial study, 90 PE technicians with LBP were randomly assigned to three groups: intervention, placebo and control. Intervention and placebo used 1.5 cc oil of chamomile and paraffin respectively, in lumbar region, three times a day for three weeks. Control group did not receive any intervention. Pain intensity and its interference with daily activities were measured by brief pain inventory (BPI), before intervention and end of first, second, and third weeks.ResultsIntervention group showed a significant drop in pain intensity and pain interference with daily activities at end of first, second, and third week (p < 0.001). At the end of first and second weeks, the mean pain reduction in intervention was significantly higher than that in placebo and control (p < 0.001), but at end of third week, there was no significant difference between three groups in this respect (p > 0.05).ConclusionTopical chamomile oil application can reduce the intensity of LBP in PE technicians and its impact on their daily activities for a period of two weeks.Copyright © 2022.
