【摘要】：目的:本研究通过测定健康男大学生长时间持续伏案过程中小脑下后动脉供血区脑氧的动态变化,了解健康男大学生长时间伏案工作过程中小脑下后动脉供血情况,为广大伏案工作人群提供颈椎自我保健的指导,为颈椎病的预防也提供相应的理论依据。方法:随机选取非术科系18-22岁健康男大学生10名。受试对象身体健康状况良好,无头、颈、肩相关疾病,实验前24h未从事剧烈运动,无疲劳症状,且受试者每周运动频率低次于3次。受试者在固定体位连续伏案160min,伏案过程中采用近红外光谱仪(NIRS)实时监测小脑下后动脉血供。通过分析NIRS测试结果,探讨长时间伏案对小脑下后动脉血供的影响。结果:1.在持续伏案160min过程中,Hb O2、t Hb随时间推移呈缓慢上升趋势,HHb随时间推移呈缓慢下降趋势;经重复测量方差检验,Hb O2不同时间点变化差别有统计学意义(F=8.666,P=0.001),t Hb不同时间点变化差别有统计学意义(F=3.059,P=0.042),HHb不同时间点变化差别有统计学意义(F=119.059,P=0.000)。2.Hb O2变化率随时间呈下降趋势,且Hb O2变化率始终大于HHb的变化率。结论:在持续伏案的160min内小脑下后动脉血流量随时间推移呈缓慢上升趋势,但Hb O2的上升幅度随伏案时间的延长逐渐减小。
[Abstract]:Objective: to investigate the blood supply of the posterior inferior cerebellar artery (PCA) in healthy male college students by measuring the dynamic changes of cerebral oxygen in the blood supply area of the posterior inferior cerebellar artery (PCA) during long-term sustained voltammetry in healthy male college students. Methods: 10 healthy male college students aged 18-22 years old in non-technical department were randomly selected. The subjects were in good health condition and headless, and provided corresponding theoretical basis for the prevention of cervical spondylosis. Neck, shoulder related diseases, 24 hours before the experiment did not engage in strenuous exercise, no symptoms of fatigue, The frequency of exercise was lower than that of 3 times a week. The subjects used NIR spectroscopy to monitor the blood supply of the posterior cerebellar artery in real time during 160 mins of continuous volt in fixed position. The results of NIRS test were analyzed. To investigate the effect of long-term voltammetry on the blood supply of the posterior cerebellar artery. Results: 1. During the continuous volt 160min, the HB O _ 2H _ b increased slowly with the passage of time, and the HB decreased slowly with the passage of time. After repeated measurement of variance, there were significant differences in the changes of HB O 2 at different time points. There was a significant difference between different time points of HbO 2, FJ 8.666U, P 0. 001H b. There was a significant difference in the variation of HbO2 at different time points. There was a decreasing trend in the rate of change of FG 119.059P0.000.2.HbO2 with time. The change rate of HB O 2 was always higher than that of HHb. Conclusion: the flow of blood in the cerebellum of 160min in continuous volt increased slowly with the passage of time, but the increase of HB O 2 decreased with the prolongation of the duration of the volt.
