Abstract: 本研究は,刺激強度の違いによる生体への影響を検索する目的で,3段階の熱刺激強度を設定し,それらが自律神経系におよぼす影響を交感神経皮膚反応(SSR)を指標に検討した.対象は健常人5名で,各被験者の閾値温度を基にその30,60,90%となる温度を熱刺激として設定し,刺激なしの場合とこれらの熱刺激を加えた場合のSSR波形振幅を検討した.結果,各条件におけるSSR波形振幅は個人差が認められたが,各被験者とも熱刺激強度が増すほど振幅は大きくなり,特に痛みとして認識する強度では,この変化が著しかった.したがって,熱刺激強度が増すにつれ交感神経活動が促進され,特に生体に対する侵害刺激では,その影響が著しくなると考えられた. / Aiming at clarifying the influences of various strengths of stimuli on human body, three different of heat stimuli were used investigate their effects on the sympathetic skin response (SSR) in the autonomic nervous system. As the subjects, five healthy adults were used and the threshold temperature of each subject was determined. Based on the respective threshold, the temperatures corresponding to 30, 60 and 90% of the threshold were given to each subject as heat stimuli and the amplitudes of SSR waves were measured. Then, the differences in the amplitude were compared between the conditions with and without the stimuli. The present results showed that there were significant differences in the amplitude of SSR wave among individuals and the amplitude became larger as an increase of the strength of stimulus. The amplitude change was remarkable, especially for the stimuli recognized as a pain. Therefore, it was thought that heat stimulus might enhance the activities of sympathetic nerve system as an increase of its strength and those effects of noxious stimuli might be marked.
