随着神经退行性疾病负担的增加,有限的临床接触不允许对复杂的神经功能进行量化。如果患者收集的数字生物标记物提供了可靠的信息,它们可能会纠正这一点。然而,数字工具的心理测量学特性在很大程度上仍未得到评估。我们开发了一个智能手机改编的认知测试,符号数字通道测试(SDMT),通过随机化测试的符号数字代码和测试序列。在154名多发性硬化症(MS)患者和39名健康志愿者(HV)中,智能手机SDMT显示出类似的心理测量学特性。例如,智能手机SDMT与神经检查的认知亚分和磁共振测量的脑损伤的相关性(R2 = 为0.75, Rho = 为0.83,p < 为0.0001)略高于传统的SDMT。通过另一项智能手机测试对优势手的运动障碍进行数学调整,弥补了基于触摸的测试的缺点。对数字生物标记物的颗粒家庭测量进行平均也可以提高识别真正神经功能衰退的准确性。
As the burden of neurodegenerative diseases increases, time-limited clinic encounters do not allow quantification of complex neurological functions. Patient-collected digital biomarkers may remedy this, if they provide reliable information. However, psychometric properties of digital tools remain largely un-assessed. We developed a smartphone adaptation of the cognitive test, the Symbol-Digit Modalities Test (SDMT) by randomizing the test’s symbol-number codes and testing sequences. The smartphone SDMT showed comparable psychometric properties in 154 multiple sclerosis (MS) patients and 39 healthy volunteers (HV). E.g., smartphone SDMT achieved slightly higher correlations with cognitive subscores of neurological examinations and with brain injury measured by MRI (R2 = 0.75, Rho = 0.83, p < 0.0001) than traditional SDMT. Mathematical adjustment for motoric disability of the dominant hand, measured by another smartphone test, compensates for the disadvantage of touch-based test. Averaging granular home measurements of the digital biomarker also increases accuracy of identifying true neurological decline.
