Congenital muscular torticollis (CMT) results from tightness of neck musculature that causes the infant to tilt the head to one side and turn it to the other side. Infants with CMT also show unequal use of both sides of the body for movement and play. In this randomized clinical trial, researchers will compare two physical therapy (PT) treatment methods, passive stretching and Perception-Action (P-A) Approach, in their effects on head position and use of both sides of the body in infants with CMT. Behavior demonstrated during PT sessions by infants in the two groups will be also compared. Thirty-six infants with CMT will be randomly assigned to a passive stretching group or a P-A Approach group. The infants in both groups will attend 5 weekly PT sessions, including the initial evaluation, 3 subsequent weekly sessions, and a re-evaluation session. At visits 1 and 5, each infant's habitual head position, the ability to turn the head to both sides, muscle strength on both sides of the neck, motor development, and use of both sides of the body for movement and play will be assessed. Each infant's behavior exhibited during therapy will be assessed at visits 2-4. Results obtained from the two groups will be compared.
It is hypothesized that:
There will be significant gains achieved by both intervention groups between the initial and final assessments on the following outcome measures:
- Still photography
- Arthrodial goniometry used to assess active head rotation to both sides
- The Muscle Function Scale (MFS) used to assess neck muscle strength
- The Alberta Infant Motor Scale (AIMS) used to assess motor development
- There will be no significant difference between the groups on the above listed measures after the intervention is completed.
- The P-A Approach group will achieve greater gains than the passive stretching group between the initial and final assessments on the Functional Symmetry Observation Scale (FSOS) used to assess the use of both sides of the body for movement and play
- The P-A Approach group will demonstrate higher Therapy Behavior Scale (TBS) scores than the passive stretching group assigned based on participants' behavior demonstrated during PT intervention sessions

Active Comparator: Passive Stretching
Passive Stretching intervention components include static passive stretching, active assistive range of motion, assisted stretching of the involved cervical musculature, and associated strengthening activities aimed to elicit head righting in developmentally appropriate positions and during developmentally appropriate movement transitions. Intervention is progressed by increasing head tilt angles, duration of head righting, and frequency and number of repetitions.
Behavioral: Passive Stretching
Passive stretching and associated strengthening activities to change head/neck and body alignment
Other Name: Passive movement, physical therapy
Active Comparator: Perception-Action Approach
P-A Approach intervention components include environmental set-up for activity and participation in play, and manual guidance in the form of light pressure applied to the infant's body in developmentally appropriate positions. Both components are designed to promote spontaneous exploration of the environment by the infant by suggesting small, incremental changes in his/her perceptual-motor orientation and contact with the support surface. Intervention is progressed by gradually removing environmental supports provided to the infant's body parts, and by removing the therapist's hands from the infant's body to allow for spontaneous exploration of a newly found contact with the support surface or new body configuration.
Behavioral: Perception-Action Approach
Environmental set-up and gentle manual guidance to promote spontaneous exploration of alternative head/neck and body alignment possibilities
Other Name: Perceptual-motor intervention, physical therapy
- Still Photography [ Time Frame: At baseline and week 5 ]Change in the angle of habitual head deviation from midline assessed in a supine position
- Arthrodial Goniometry [ Time Frame: At baseline and week 5 ]Change in the angular difference in active cervical rotation range of motion between the involved and uninvolved sides
- Muscle Function Scale (MFS) [ Time Frame: At baseline and week 5 ]Change in the MFS score that reflects the difference in strength of lateral neck flexor muscles during head righting between the involved and uninvolved sides
- Functional Symmetry Observation Scale (FSOS) [ Time Frame: At baseline and week 5 ]Change in the FSOS score that reflects functional use of both sides of the body during spontaneous movement and play
- Alberta Infant Motor Scale (AIMS) [ Time Frame: At baseline and week 5 ]Change in the AIMS score that reflects gross motor development while also considering symmetrical postural alignment and symmetrical use of both sides of the body during movement and play
- Therapy Behavior Scale (TBS) [ Time Frame: Weeks 2, 3 and 4 (at the time of intervention sessions 2, 3 and 4) ]The TBS score documents therapy-related behavior during intervention sessions; to be used for between group comparison only.
