### Summary box #### What are the new findings? #### How might it impact on healthcare in the future? Viral warts are common cutaneous infections, with 2% of the general population seeking medical care annually.1–3 In a study involving school children, the annual incidence rate of plantar warts was 14%.4 Cryotherapy is often first-line therapy in dermatological clinics. We have previously found that patients exhibit significant pre-procedural anxiety due to cryotherapy-related pain and discomfort.5 There are vibratory devices proven to relieve injection-associated discomfort and pain in dermatological and facial procedures, such as botulinum toxin or filler injections.6 7 Devices used range from commercially available inexpensive body massagers to specific vibrating devices designed for medical or dental use.8 Most are not intended for use in clinical procedures and unable to achieve maximum benefit in terms of pain relief.9 Currently, a commercially available device, Buzzy (MMJ Labs, Atlanta, Georgia, USA), was shown to significantly lower venepuncture associated pain in paediatric populations.10 11 Buzzy also lowered lower extremity injection associated pain when strapped on proximally to the injection site. However, the device was applied away from the site of procedure and there were reported difficulties applying …

使用非侵入性振动装置冷冻治疗足底病毒性疣期间的疼痛缓解：一项随机个体间对照试验

### 摘要框#### 有哪些新发现？#### 它对未来的医疗保健有何影响？病毒性疣是常见的皮肤感染，每年有 2% 的普通人群寻求医疗护理。1-3 在一项涉及学童的研究中，跖疣的年发病率为 14%。4 冷冻疗法通常是皮肤病学的一线治疗诊所。我们之前已经发现，由于冷冻疗法相关的疼痛和不适，患者表现出明显的术前焦虑。 5 已经证明振动装置可以缓解皮肤病和面部手术中注射相关的不适和疼痛，例如肉毒杆菌毒素或填充剂注射。 6 7 使用的设备范围从市售的廉价身体按摩器到专为医疗或牙科使用而设计的特定振动设备。8 大多数不适用于临床手术，无法在缓解疼痛方面获得最大益处。 9 目前，商业上可用的设备 Buzzy（美国乔治亚州亚特兰大 MMJ 实验室）显示可显着降低与静脉穿刺相关的疼痛在儿科人群中。10 11 Buzzy 还可以降低下肢注射相关的疼痛，当绑在注射部位的近端时。然而，该装置是在远离手术部位的地方使用的，并且据报道难以使用…… 10 11 当Buzzy 绑在注射部位的近端时，Buzzy 还降低了下肢注射相关的疼痛。然而，该装置是在远离手术部位的地方应用的，据报道，应用存在困难…… 10 11 当Buzzy 绑在注射部位的近端时，Buzzy 还降低了下肢注射相关的疼痛。然而，该装置是在远离手术部位的地方使用的，并且据报道难以使用……
