The 46 patients were investigated with the congenital infant muscular torticollis referred Dept. of physical therapy in Dong San Medical Center from January in 1995 to January in 1996. 1. The ratio between males and females was scaled to 1.5 : 1.23 cases(50.0 %) were involved with left side and 22 cases(47.8 %) involved with right side, and one case was of bilaterality. 2. Sequence of birth, the first bone babys were the most distributed with 34cases(73.9 %), the second bone babys were followed with 11cases(23.9 %). 3. There were normal deliveries 60.8 %, Cearean section deliveries 23.9 %, difficulty deliveries .0 % and breech presentation was 2.2 %. 4. The case of cephalic asymmetry consisted 60.0 % of all congenital torticollis and most frequently found at the age of all $5sim8$ weeks(45.7 %). In 26.1 % of all congenital torticollis cases, facial asymmetry was found and these cases were most frequently in the age of $5sim8$ weeks(26.1 %), also in the age group of $9sim12$ weeks and $17sim20$ weeks consecutively(each 3 %).(P<0.05) 5. The duration of therapy required differently according to the severity of the torticollis, in mild cases, it took $1sim2$ weeks cases(30.4 %) revealed high therapeutic effect in 54.3 % of the cases. In moderately involved cases(30.4 %), therapy required $3sim4$ weeks in 13 % of the cases showed improvements. In the most severely involved cases, (7 %) it took more than $9sim10$ weeks of therapy and showed improvement in 6.5 % only.(P<0.005) 6. The result of this study showed the best therapeutic effects were noticed in the mild cases of congenital torticollis(24 cases 45.6 %) and excellent improvement in moderately involved cases (28.1 %) and 13.1 % of the most severely involved cases(P<0.05).
