音楽運動療法を取り入れたグループ椅子体操は手軽で楽しく、介護予防としても機能訓練としても利用価値の高いものとされている。本研究は本音楽運動療法の精神面への効果を科学的に証明する事を目的として、男性3名、女性17名の健常高齢者20名(66歳～86歳、平均年齢76.3歳)の音楽運動療法実施前後における唾液を採取し、唾液量やストレスに関与する唾液中の内分泌物質を測定した。その結果、音楽運動療法実施後に唾液量は有意に増加し(1350.5±800.98 μl→1786.5±780.54 μl、mean±SD、p＜0.01)、コルチゾールは、有意に減少(0.19±0.10 μg/dl→0.13±0.07 μg/dl、p＜0.001)したが、pHやクロモグラニンAにおいて有意な変化は見られなかった。参加者のアンケート(POMS短縮版)による気分変化においては、疲労感が有意に減少(3.63±4.09→2.30±3.13、p≦0.05)した。

本音楽運動療法プログラムは、主観的な疲労感の回復効果のみならず、客観的なリラクゼーション効果もあることが生化学的に証明された。

This paper demonstrated a relation between tempo of ‘Healing’ music and listener's ‘Healing’ evaluation. Some previous studies suggested that tempo is one of the most important factors in music. In present study, at first, we investigated tempo of ‘Healing’ music from the market, and analyzed acoustical property of them. Next, we made a simple sound from a result of the analysis, and we used it in the listening experiment. The subjects answered subjective ‘Healing’ impression of the sound stimuli, which were constructed from simple sounds in various tempi. According to the confirmation, the peak of the evaluation value was found at about 60 BPM (Beats Per Minute). Distribution of subjective ‘Healing’ evaluation resembled distribution of tempo values of ‘Healing’ music. There must be a tempo that fitsKANSEIand heals us, and such tempo is possible to be originated from heart rate in rest. Results of this study are useful for composition and choice of ‘Healing’ music.

Leukocytes are divided into two major types, granulocytes and lymphocytes. Granulocytes are activated in number and function under sympathetic nerve stimulation, whereas lymphocytes are activated under parasympathetic nerve stimulation. We analyzed the ratio of leukocytes and the time-domain (%RR50) from R-R interval variability to investigate the differences in autonomic nervous system activity in 10 healthy female subjects (age 51.2±8.7 years). The purpose of this study was to investigate whether or not variation in the ratio of leukocytes in the blood was equivalent to the variation in %RR50, and whether the autonomic nervous system, endocrine secretion and immune mechanism interacted. The subjects were grouped according to the mean values of the ratio of lymphocytes among the leukocytes when in a sitting position. The granulocytes group (GG : 5 persons) had below average values for the ratio of lymphocytes among the leukocytes, and the lymphocytes group (LG : 5 persons) had above average values. The measurements were taken during spontaneous breathing for 15 min at rest, followed by YOGA breathing (voluntary control of abdominal breathing : expiration to inspiration time ratio was 2 to 1) for 15 min and recovery with spontaneous breathing in a sitting position for 30 min. The R-R intervals were measured 8 times for 60 min as well as heart rate (HR), blood pressure (BP), and respiratory frequency (f). Blood was drawn 3 times for 60 min and the erythrocyte·leukocyte·thrombocyte·hemoglobin (Hb) and hematocrit (Hct) levels were examined. The leukocytes were classified as neutrophil, eosinophil, basophil, monocyte or lymphocyte. Furthermore the catecholamine : adrenaline, noradrenaline and dopamine (CA : Adr, Nad and DA), cortisol and immunoglobulin A (IgA) levels were observed.
It was confirmed that the variation in the ratio of leukocytes was equivalent to the variation of %RR50, both of GG and LG. With regard to the characteristics of each group, the following were observed : GG showed an accelerated trend of sympathetic nervous system activity and high values were obtained in the measurements of BP, Adr, Nad, cortisol and low values in the measurements of IgA and %RR50 at rest. LG showed an accelerated trend of parasympathetic nervous system activity and high values were obtained in the measurements of IgA and %RR50 and low values in the measurements of BP, Adr, Nad, and cortisol at rest. LG was characterized by consistently low blood pressure and respiratory frequency. These results indicated that there were natural differences in each subject in their autonomic nervous system activity and physiological function at rest. However, it was found that YOGA breathing (voluntary control of abdominal breathing) enhanced vagal modulation of the heart rate and the lymphocytes gradually increased in subjects who showed an accelerated trend of sympathetic nervous system activity. During all of the trials, it has been shown that activities of the autonomic nervous system, endocrine secretion and immune mechanism interacted.
It was suggested that the distribution of leukocytes is not only related to immunity, but also is an indication of physical and mental stress and physical condition.

音楽を用いる場合，音楽療法，音楽鑑賞，音楽活動のアプローチがあるが，音楽の直接的効果と言うよりもストレス軽減による間接的効果と考える方が妥当である。そのような観点では，他の補完代替医療にもアトピー性皮膚炎への効果が期待できるものがある。メディカル・アロマセラピーは，精油の薬効成分を用いるものであるが，ストレス軽減には，鎮静，鎮痒，殺菌作用のあるラベンダーなどの精油が向いている。レイキは，日本の「手当て」が発展したものであるが，アルミホイルで伝達が遮断されることから電磁波様のエネルギーであると考えられる。筋緊張軽減，疼痛緩和，末梢循環改善などの作用があり，リラクゼーション効果は大きい。(皮膚の科学，増20: 7-12, 2013)

中等度難聴と推測された重症心身障害者2名に対して、スピーカーによる音楽呈示と体感音響装置を用いた振動を伴う音楽呈示をABABデザインで行い、音楽呈示に伴う行動反応と生理的な反応について分析した。その結果、音楽のみの呈示よりも体感音響装置を用いた音楽呈示において、覚醒を示すと思われる「開眼」が多く見られ、音楽開始時には、刺激に対する定位反応と考えられる心拍の減速反応が認められた。さらに、音楽呈示後、聴覚のみに働きかける呼名に対しても、心拍の減速反応が認められた。一方、体感音響装置を用いた音楽呈示により、ストレスを反映すると思われる唾液アミラーゼ活性値が上がる傾向は認められなかった。以上のことから、体感音響装置を用いた音楽は、重症心身障害者にとって過度なストレスとはならずに、覚醒を促す刺激として受容される可能性が示唆された。そのため、身体状況に配慮しつつ体感音響装置による音楽呈示を定期的・継続的に行うことは、重症心身障害者の身体状況の改善や生活の質の向上に寄与しうるものと考えられた。
