Reducing Hormonal Manifestations of Stress
during Labor
Already normal labor is accompanied by great physical and emotional stress. This is even more the case when complications come up as with women with an initial inactivity of the uterus.To find out in how far Medical Reso­nance Therapy Music® has a harmonizing ef­fect on neuroendocrine functions important opioids for adaptation and stress were cho­sen for investigation:
    1. beta-endorphin,
    2. corticotrophin (ACTH)
    3. and cortisol
– hormones which show extremely high levels in blood during labor and which are typical for stress conditions.

Under investigation were three groups:
  1. one group of 11 women was treated with relaxing Medical Resonance Ther­apy Music®,
  2. a control group A of 11 women listened to music of Mozart – Symphony No. 28 and Coronation Mass – and
  3. a control group B of 11 women did not listen to any music.

Medical Resonance Therapy Music® Group

The treatment with the Medical Resonance Therapy Music® resulted in a significant change of the hormonal situation: the beta-endorphin value dropped by 6.05 units and also ACTH showed a tendency to decrease – the hy­per­pro­duc­tive hormone system was calmed, hor­mo­nal manifestations of stress reduced and a more balanced state established.

Control Group A

Here too a significant change was found in the hormonal situation, but in the opposite di­rec­tion: the ACTH level increased – the al­ready hyperactive hormone system got even more exaggerated, hormonal manifestations of stress increased.

Control Group B

Here no significant changes were observed, only small variations.

Comments to Cortisol

A significant change of cortisol was neither found in the “Mozart group” nor in the Medical Resonance Therapy Music® group. To get a reliable picture of the changes in cortisol level probably a longer than 30 minute treatment interval is necessary, since its duration is comparable with half the life span of the hor­mone in circulation.
