The results obtained from a survey of balneal treatment and medical researches made mainly by means of the CMI card method at Tamagawa Spa in Akita Prefecture are summarized as follows;
1) The spa visitors were about 540 in number, women being twice as many as men. Classified into age group, the number of visitors was almost equal in each group, and classified into occupations, farmers were the largest in number.
2) The visitors came from nearly all parts of Japan, but the majority of them were from Akita Prefecture: 61.7%. Of all the visitors, 52.1% came either for treatment or for recuperation and 31.9% for recreation.
3) This survey revealed that visitors without diseases were 47.9%. Of those who visited the consulting room, the patients with the circulatory diseases were the largest in number.
4) The occurrence of bathing reaction was observed in 37.9%, and those with dermatitis were 21.2%.
5) Those who drank hot-spring waters were 28.4%.
6) The majority of visitors stayed for one or two weeks, bathing three to four times a day.
7) Only 5.5% of visitors came there under doctor's directions, and 6.8%, of them came having information from newspaper or magazine articles. Most of the visitors came there based on their own experience or on others' recommendation.
8) In the CMI, of 236 visitors, 67 were classified into the 1st group (28.4%), 88 into the 2nd group (37.3%), 56 into the 3rd group (23.7%), and 25 into the 4th group (10.6%). Of 108 controls, 45 were classified into 1st group (41.7%), 43 into the 2nd group (39.8%), 17 into the 3rd group (15.7%) and 3 into the 4th group (2.8%). Thus the 3rd and 4th group were quite large in number among the spa visitors. Very few of the visitors over 60 years of age belonged to the 3rd and 4th group. The number of men and women was almost equal in each group.
9) Those who belonged to the 3rd and 4th group were found in the patients with circulatory diseases more than in those with other diseases.
10) No relation seemed to exsist between the ratio of the body length to weight and CMI classification.
11) Of the visitors, 62.4% had the systolic hypertension and 48.9% diastolic hypertension. No definite relation was observable between blood pressure and CMI classification.
12) Of the visitors, studied by means of the CMI card method, 112 visitors were chosen at random for electrocardiograms, of whom 10 were classified into the abnormal group (8.9%), 38 into the semi-abnormal group (33.9%), and 64 into the normal group (57.2%). Incidence of the 3rd and 4th group was high in the abnormal electrocardiogram group.
The incidence of the 3rd and 4th group is higher in the cases with sinus tachycardia, arrhythmia, abnormal p wave, bundle branch block and severe ST-T change than in the subjects with sinus bradycardia, prolonged P-Q interval, premature beat, left ventricular hypertrophy and slight ST-T change.
13) CMI card method was useful for screening neurosis out of the mass.
