Objective: To observe the clinical efficacy of different media in pediatric tuina treatment for children with muscular torticollis. Methods: A total of 80 children with muscular torticollis were randomized into an observation group and a control group, 40 cases in each group. Both groups received conventional pediatric tuina therapy. The observation group was treated with Bai Mai ointment as the massage medium, while the common lubrication oil was used as medium in the control group. Both groups were treated five times a week, 20 min for each time, 20 times constituted a course of treatment. The traditional Chinese medicine (TCM) syndrome scores were evaluated before and after treatment, and the curative effect was observed after 3 courses and 6 courses of treatment respectively. Results: The TCM syndrome scores improved in both groups after treatment, and the intra-group differences were statistically significant (both P<0.01). The score of the observation group was statistically different from that in the control group (P<0.05). In the observation group, the total effective rates after 3 courses and 6 courses of treatment were 95.0%and 100.0%, respectively, versus 87.5% and 95.0% in the control group. The total effective rates of the two groups were statistically different (both P<0.05). Conclusion: Bai Mai ointment has a better curative effect than the common lubricating oil as a massage medium in the treatment of children with muscular torticollis.
