The effect of tuinatherapy with chamomile oil extract on the severity of back pain in female operating room technologists: A randomized clinical trial

Background & Aim: Back pain is highly prevalent among operating room technologists, and conventional treatments—such as non-steroidal anti-inflammatory drugs—are often associated with adverse long-term side effects. This study aims to evaluate the effect of Tuinatherapy massage with chamomile oil extract on the severity of back pain in female operating room technologists. Methods & Materials: This double-blind, randomized controlled clinical trial included 105 female operating room technologists selected via convenience sampling from several hospitals in Isfahan. Participants were randomly assigned to three groups of 35 individuals each: (1) Tuinatherapy massage with liquid oil supplemented with chamomile oil extract, (2) Tuinatherapy massage with liquid oil alone, and (3) a control group receiving no intervention. The Tuinatherapy massage sessions consisted of 10 sessions, each lasting 20 minutes and conducted every other day. Pain intensity was measured using the Visual Analog Scale (VAS) both before and after the intervention. Data analysis was performed using SPSS version 27, using one-way ANOVA and Tukey’s post hoc tests. Results: Significant reductions in pain intensity were observed in groups one and two following the intervention compared to baseline (P<0.001). The control group showed no significant change. Prior to the intervention, there were no significant differences in pain scores among the three groups (P=0.230); however, post-intervention, pain intensity in group one was significantly lower than that in groups two and three (P<0.001). Conclusion: Tuinatherapy massage effectively reduces back pain severity among female operating room technologists. Moreover, the inclusion of chamomile oil extract enhances this therapeutic effect. As an alternative to pharmacologic treatments, Tuinatherapy massage with chamomile oil may serve as a method for alleviating back pain in this population. Clinical trial registry: IRCT20220725055548N1
