title: A comparison of outcomes of asymmetry in infants with congenital muscular torticollis according to age upon starting treatment.
abstract: [Purpose] The purpose of this study was to compare the outcomes of asymmetry in infants with congenital muscular torticollis (CMT) according to the age when treatment was started. [Subjects and Methods] 102 infant CMT patients under the age of 6 months were selected. The subjects were divided into a group that started treatment before six weeks (n=55) and a group that started treatment after six weeks (n=47). Asymmety was evaluated by determining the difference in the thickness of the two sternocleidomastoid muscles (DTSM) using ultrasonography, head tilt (HT) based on a physical examination, and the torticollis overall assessment (TOA). Patients received ultrasound and massage therapy for 30 minutes, in conjunction with passive stretching exercises, 3 times a week. [Results] Following the intervention, the DTSM, HT and TOA showed significant differences in the two groups. The DTSM of the group that started treatment before six weeks was significantly better than that of the group that started treatment after six weeks. [Conclusion] The results of this study suggest that early intervention is more effective than later intervention.
