项目摘要

This research consists of three experiments. [Experiment 1] Activation of a healthy adult brain function was considered as basic research. Subjects are 12 healthy older adults (mean age 73.5) and 16 younger adults (mean age 22.0). First the subjects were instructed to lay in supine position. Then they turned to prone position by themselves. And after 10 minutes they turned again to supine position. In each position, the brain waves(EEG) and heart rate variability(HRV) were measured. In EEG, the prone position amplified the β waves in both groups. In HRV, we observed that the RR intervals were significantly extended after the prone position in both groups. [Experiment 2] : Optical Topography estimated the difference in the brain blood flow at the time of prone position and supine position to 17 healthy adults (mean age 22.9). At the time of prone position, the brain blood flow increased from the time of supine position. [Experiment 3] : The effect of the prone position intervention of eight aged persons(62 to 90 years old) in a nursing home for the aged was specially examined. Prone position for 30 minutes was carried out once per day for three weeks. EEG, HRV were examined once at one week and observation of speech and conduct was performed. In EEG, we observed that the β wave were significantly increased on frontal section. Though LF/HF increased, there was no significant difference. Thus we considered that the position helps to activate the functions of the cerebrum. In HRV, although strain of the sympathetic nerve might be caused slightly, the number of cardiac beats became fewer and stable. The degree of oxygen saturation in arterial blood is high, and the ventilation function was enough. It can be said that this influence is effective as position management for an aged person, stimulating low ADL elderly people's cerebrum and brain stem part, and being activated.

本研究由三个实验组成。[实验1]以激活健康成人脑功能为基础研究。受试者为12名健康的老年人(平均年龄73.5岁)和16名年轻人(平均年龄22.0岁)。首先，受试者被指示仰卧。然后他们自己转向俯卧姿势。10分钟后，他们又转过身来，恢复仰卧姿势。测定每个体位的脑电波(EEG)和心率变异性(HRV)。在脑电中，俯卧位对两组的β波都有放大作用。在心率变异中，我们观察到两组患者在俯卧位后RR间期均显著延长。[实验2]：光学地形图估计了17名健康成人(平均年龄22.9岁)俯卧位和仰卧位时脑血流量的差异。俯卧位时，脑血流量从仰卧位开始增加。[实验3]对某养老院8名62~90岁老年人进行俯卧位干预，观察干预效果。俯卧位30min，每日1次，连续3周。每周检查一次脑电、心率变异性，并进行言语和行为观察。在脑电中，我们观察到β波在额部明显增加。虽然LF/HF升高，但差异无统计学意义。因此，我们认为这个位置有助于激活大脑的功能。在心率变异性中，交感神经虽有轻微拉伤，但心搏次数减少且稳定。动脉血氧饱和度高，通气功能良好。可以说，这种影响是对老年人进行体位管理，刺激ADL低的老年人的大脑和脑干部，并被激活的有效方式。
