Current scientific evidence on the effect of Extracorporeal Shock Wave Therapy (ESWT) as adjunctive treatment for burn scars is scarce. However preliminary evidence, indicates it might prove a useful tool.
A prospective, randomized, controlled study was conducted from February 2017 to February 2019. Patients with burn scars were divided into two groups with twenty patients per group. The control group received the standard treatment for burn scars. The ESWT group received the standard treatment and treatment of burn scars with ESWT 512 impulses of 0.15mJ/mm in each session, twice per week for 4 weeks. We assessed the appearance of scar with the Vancouver Scar Scale (VSS), pruritus and pain with Visual Analog Scale (VAS) before the start of the treatment and at 2 weeks and 5 months after the treatment.
Both groups showed improvements in all variables through the study. However, these improvements were only statistically significant for the VSS at the 6th month for the control group and VSS and VAS pain and pruritus for the ESWT group. Nonetheless the results failed to show statistically significant differences between the ESWT and the control group neither at two weeks after treatment nor at 5 months after treatment.
Our study questions the relevance of ESWT as adjunctive treatment for burn scars as far as outward appearance, pain and pruritus as end-results are concern. Nonetheless, further studies are required to accurately assess the potential benefits of ESWT as an adjunctive treatment for burn scars.
关于体外冲击波疗法（ESWT）作为烧伤瘢痕辅助治疗效果的现有科学证据稀缺。然而，初步证据表明它可能是一种有用的工具。
2017年2月至2019年2月进行了一项前瞻性、随机、对照研究。烧伤瘢痕患者分为两组，每组20例。对照组接受烧伤瘢痕的标准治疗。ESWT组接受标准治疗以及用ESWT治疗烧伤瘢痕，每次治疗512次脉冲，能量为0.15mJ/mm，每周两次，共4周。在治疗开始前、治疗后2周和5个月，我们用温哥华瘢痕量表（VSS）评估瘢痕外观，用视觉模拟量表（VAS）评估瘙痒和疼痛情况。
在整个研究过程中，两组在所有变量上均有改善。然而，这些改善仅在对照组第6个月的VSS以及ESWT组的VSS、VAS疼痛和瘙痒方面具有统计学意义。尽管如此，结果显示ESWT组与对照组在治疗后2周和治疗后5个月均未显示出统计学上的显著差异。
就外观、疼痛和瘙痒这些最终结果而言，我们的研究对ESWT作为烧伤瘢痕辅助治疗的相关性提出了质疑。尽管如此，仍需要进一步研究来准确评估ESWT作为烧伤瘢痕辅助治疗的潜在益处。
