摘要：
触觉感知在日常生活活动中发挥着重要作用，而在患有某些疾病的个体中，触觉感知可能受损。用于评估触觉的最常见工具是 Semmes-Weinstein 单丝和 128 Hz 音叉，但它们的可重复性和分辨率较差。长期而言，我们的目标是提供一种可重复、高分辨率的测试平台，能够通过智能手机评估振动触觉感知，且无需实验人员在场实施测试。我们提出了一种基于智能手机的振动感知测量平台，并将其性能与标准单丝测试和音叉测试的测量结果进行比较。我们开展了一项包含 36 名健康成人的用户研究，在手部、腕部和足部对每种工具进行测试，以评估我们基于智能手机的振动感知阈值（VPT）能够在多大程度上检测到标准测试所得的已知趋势。该智能手机平台检测到了食指与足部之间 VPT 的统计学显著变化，也检测到了较年轻成人与较年长成人足部之间 VPT 的统计学显著变化。我们基于智能手机的 VPT 与基于音叉的 VPT 具有中等程度相关性。我们的总体目标是开发一种易于使用的智能手机平台，最终可用于测量疾病的进展与消退。
英文摘要：
Tactile perception plays an important role in activities of daily living, and it can be impaired in individuals with certain medical conditions. The most common tools used to assess tactile sensation, the Semmes-Weinstein monofilaments and the 128 Hz tuning fork, have poor repeatability and resolution. Long term, we aim to provide a repeatable, high-resolution testing platform that can be used to assess vibrotactile perception through smartphones without the need for an experimenter to be present to conduct the test. We present a smartphone-based vibration perception measurement platform and compare its performance to measurements from standard monofilament and tuning fork tests. We conducted a user study with 36 healthy adults in which we tested each tool on the hand, wrist, and foot, to assess how well our smartphone-based vibration perception thresholds (VPTs) detect known trends obtained from standard tests. The smartphone platform detected statistically significant changes in VPT between the index finger and foot and also between the feet of younger adults and older adults. Our smartphone-based VPT had a moderate correlation to tuning fork-based VPT. Our overarching objective is to develop an accessible smartphone-based platform that can eventually be used to measure disease progression and regression.
