The F-Scan (F-Scan System by Tekscan, Boston, USA) is an in-shoe pressure measurement device used to provide dynamic pressure, force and timing information to guide appropriate offloading of plantar foot ulcers. Despite the clinical utility of an in-shoe pressure measuring device there are some limitations in the validity and reliability of the output of the F-Scan. The aim of this study was to develop a consensus-based guideline following information provided by experienced clinicians, synthesis of research evidence and manufacturer's guidelines on the most appropriate use and interpretation of the data generated by the F-Scan to manage plantar foot ulceration.
Using the Delphi method a series of sixteen consensus statements were developed following a two-step questionnaire utilising clinicians feedback, a review of evidence and the manufacturer's guidelines.
Seventeen clinicians responded to the first questionnaire and 11 to the second, that included 8 podiatrists and 9 pedorthists working in the public and private sectors. Of the sixteen statements there was strong consensus for ten and moderate consensus for a further four. Only two statements failed to reach consensus and the feedback from the respondents was of great value providing sound clinical rationale for their rejection.
The objective of this study has been achieved in developing a clear and concise set of guiding statements (Table 1) to standardise use of the F-Scan. The application of the guiding statements will encourage standardisation of practice with the aim of highlighting the limitations of the system and reducing potential systematic error in measurement from output produced.
F-Scan（美国波士顿 Tekscan 公司的 F-Scan 系统）是一种用于提供动态压力、力和计时信息的鞋内压力测量设备，用于指导足底溃疡的适当减压。尽管鞋内压力测量设备具有临床实用性，但 F-Scan 的输出在有效性和可靠性方面存在一些限制。本研究的目的是制定一项基于共识的指南，该指南遵循经验丰富的临床医生提供的信息、研究证据的综合以及制造商关于 F-Scan 生成的数据的最适当使用和解释的指南，以管理足底溃疡。
使用 Delphi 方法，在利用临床医生反馈、对证据进行审查和制造商指南的两步式问卷的基础上，制定了一系列十六项共识声明。
共有 17 名临床医生对第一个问卷做出了回应，其中 11 名对第二个问卷做出了回应，包括在公共和私营部门工作的 8 名足病医生和 9 名矫形师。在这 16 项声明中，有 10 项得到了强烈共识，另外 4 项得到了中度共识。只有两项声明未能达成共识，而来自受访者的反馈非常有价值，为他们的拒绝提供了合理的临床理由。
本研究的目的是制定一套清晰简洁的指导声明（表 1），以标准化 F-Scan 的使用。指导声明的应用将鼓励实践的标准化，旨在突出系统的局限性，并减少测量输出中潜在的系统误差。
