Objective To explore the clinical effect of the combination of transdermal administration of traditional Chinese medicine and Bojin massage technique in patients with contracted scar. Methods A total of 104 patients with post-burn contracted scar admitted to Hefei Changfeng Beicheng Guang'an Traditional Chinese Medicine Hospital from December 2021 to December 2022 were selected. According to the random number table method, they were divided into the control group and the experimental group, with 52 patients in each group. The control group was treated with Bojin massage technique to release the scar, and the experimental group was treated with transdermal administration of traditional Chinese medicine combined with Bojin massage technique. The clinical effect, scar severity [Observer Scar Assessment Scale (OSAS) and Patient Scar Assessment Scale (PSAS)], overall scar condition [Vancouver Scar Scale (VSS)] and satisfaction score were compared between the two groups. Results The total effective rate in the experimental group was higher than that in the control group (P<0.05). The color, thickness, roughness, surface area scores and total score of OSAS and pruritus, scar thickness, hardness and color scores of PSAS in the experimental group were better than those in the control group (P<0.05). After treatment, the scores of each dimension of VSS in the experimental group were lower than those in the control group (P<0.05). The satisfaction score in the experimental group was (7.46 ±1.13) scores, which was higher than (2.69±1.42) scores in the control group (P <0.05). Conclusion The combination of transdermal administration of traditional Chinese medicine and Bojin massage technique can effectively soften the scar, reduce the scar severity, relieve patients' discomfort of the skin lesion, and patients' satisfaction with the treatment is high.
