Abstract：Objective To discuss the feasibility of quantitative analysis for reviewing soldiers' stress reactions based on pulsation waveform features of fingertip volumetric blood flow (VBF).Methods Recruits (n=58) and veterans (n=57) were randomly and hierarchically chosen, and given stimulation by using pictures with negative emotion. The quantization parameters of pulsation waveform features of fingertip VBF were compared within groups and between groups by using HC2180-D finger-clip noninvasive detection system before and after picture stimulation, taken subjective stress report [Grade of Brief Profile of Mood State (BPOMS)] and objective stress parameters (salivary cortisol level) as criteria.Results Under the stimulation of pictures with negative emotion, constriction-dilation fraction (CDF) and value of barycenter ordinate (Y2) of vasoconstriction phase area increased significantly in 2 groups (CDF:Frecruit=7.44,P<0.01,Fveteran=4.77,P<0.01;Y2:Frecruit=3.60,P<0.05,Fveteran=4.98, P<0.01). The comparison between 2 groups showed CDF and Y2 were higher in recruit group than those in veteran group (CDF: 93.89±10.50/89.83±9.32,t=2.18,P<0.05; Y2: 36.39±6.31/34.05±6.07,t=2.00,P<0.05). CDF and total BPOMS score showed a moderate positive correlation (rrecruit=0.51,rveteran=0.49,P<0.05). Y2 and total BPOMS score showed a moderate positive correlation (rrecruit=0.48,rveteran=0.45,P<0.05).Conclusion The quantitative analysis based on pulsation waveform features of fingertip VBF has higher sensitivity and operability in review of soldiers' stress status.
