The theme of investigation was in how far blood pressure could be reduced by Medical Resonance Therapy Music® on a short and long term basis. Out of 68 patients suffering from  neurodermatitis and psoriasis two experimental groups and two control  groups were formed. Experimental group 1 counted 28 neurodermatitis  patients and experimental group 2 counted 20 psoriasis patients. The  two control groups counted 10 patients each.
      
      The age of the patients ranged from 18 to 60 years, the duration of the  investigation was 2 weeks. Blood pressure was measured at the first,  third, sixth and fourteenth day before and after treatment with  MRT-Music®. At the beginning the average systolic value was 130 mm hg and the average diastolic value 85 mm hg in all four groups.
      
      At the first day of treatment the average blood pressure in the  experimental groups reduced from 130 / 85 mm hg before treatment to 125 /  80 mm hg after treatment.
      
      This recurred at the third and sixth day of treatment. At the fourteenth  day though blood pressure reduced from 130 /85 mm hg before treatment  to 120 / 70 mm hg after treatment. Here a training effect became  evident: with proceeding application the effectiveness of MRT-Music® treatment increased.
      
      In the control group no changes could be observed.
