1. i) In threatened premature labor, viewed from a uterine contraction wave and a subjective complaint obtained by means of a cardiotocogram, B waves and L waves were observed in many cases when the patient complained of a lower abdominal pain and/or lumbago.With these pains, or with a complaint of abdominal distension, the threatened premature labor is possible, and an objective evaluation of uterine contractions by means of the cardiotocogram is necessary.The uterine contraction was recorded with a cardiotocogram.The recorded waves were evaluated by Nakae's classification (1978), and given points for each wave : 1 point for A wave, (31-60 sec), 1.5 point for B wave (61-180 sec).ii) From this study, as a prime therapeutic factor, the wave of uterine contractions with less than two contractions (A and/or B waves) in 30 minites, i.e. below 3 points of contraction is provided.2. Correlativity between these points and lower abdominal pain and lumbago is heightened and subjective complaints are increased as the point of uterine contraction becomes larger.3. In the case of 4 points of contraction or more, subjective complaints with lower abdominal distension, lower abdominal pain and lumbago were considerably increased.4. In the case of uterine contractions with more than 7 points having such pains as lower abdominal pain and lumbago, the patient was prematurely delivered at a relatively earlier time.5. The uterine contraction, one of the four factors in Tocolytic Index (T.I.) (Baumgarten, 1974) which is frequently used in foreseeing pre-term delivery mentions just irregular or regular. To assure more concrete determination, we studied the uterine contraction points in order to apply them to T.I.
