研究了脊髓损伤对皮肤血流振荡非线性复杂性的影响。用去趋势波动分析（DFA）得到的标度系数和多重分形去趋势波动分析（MDFA）得到的标度系数在特定尺度区间内的取值范围来描述BFO嵌入特征频率的复杂度。本研究共招募了23名受试者，包括11名脊髓损伤患者和12名健康对照。用激光多普勒血流仪测量局部加热诱导的骶部皮肤最大血流量。结果显示，在最大血管舒张期，SCI患者代谢BFO （0.0095 ~ 0.02 Hz）的复杂性显著低于健康对照组（p<0.01）。本研究表明，BFO复杂性分析可以提供传统光谱分析所不能提供的血流动力学信息。
This study investigated the effect of spinal cord injury (SCI) on nonlinear complexity of skin blood flow oscillations (BFO). Complexity of the characteristic frequencies embedded in BFO was described by the scaling coefficient derived by detrended fluctuation analysis (DFA) and the range of scaling coefficients derived from multifractal detrended fluctuation analysis (MDFA) in specific scale intervals. 23 subjects were recruited into this study, including 11 people with SCI and 12 healthy controls. Local heating-induced maximal sacral skin blood flow was measured by laser Doppler flowmetry. The results showed that metabolic BFO (0.0095-0.02 Hz) exhibited significantly lower complexity in people with SCI as compared with healthy controls (p<0.01) during maximal vasodilation. This study demonstrated that complexity analysis of BFO can provide information of blood flow dynamics beyond traditional spectral analysis.
