Perception-Action Approach Versus Standard Care for Infants With Congenital Muscular Torticollis: A Pilot Single-Blind Randomized Controlled Trial.

Objective The purposes of this pilot study were to compare short-term outcomes of the Perception-Action Approach (P-AA) and standard care based on 5 components of first-choice interventions listed in the congenital muscular torticollis (CMT) clinical practice guideline. Changes in postural alignment, symmetrical use of both sides of the body during movement and play, gross motor development, and behavior observed during therapy were considered. Methods Thirty-two participants were enrolled in a 2-group (P-AA and standard care) randomized, single-blind trial with pre–posttest measures. Participants were infants with CMT, age range 5 to 35 weeks at enrollment. Outcome measures administered at initial and final evaluations included still photography, arthrodial goniometry, Muscle Function Scale, Alberta Infant Motor Scale, and Functional Symmetry Observation Scale. Participants in both groups attended 3 intervention sessions. Their behavior exhibited during therapy was compared using the Therapy Behavior Scale Version 2.2. Results Data collection was interrupted by the COVID-19 pandemic lockdown. Twenty-four infants completed the study (10 in P-AA and 14 in the standard care group). There were no significant differences between the groups in performance at initial and final evaluations. Both groups improved on most outcome measures. The P-AA group made greater gains on the Functional Symmetry Observation Scale, and the Therapy Behavior Scale Version 2.2 scores were higher in the P-AA group; however, these results did not reach significance. Conclusion Results suggest that similar short-term outcomes may be obtained in infants with CMT undergoing P-AA and standard care interventions. Definitive conclusions regarding the efficacy of the P-AA in infants with CMT cannot be made at this time. Nevertheless, the pilot findings provide valuable preliminary data for a future efficacy trial, which will require funding. Impact This was the first randomized controlled trial to provide evidence for use of P-AA intervention in infants with CMT. Lay Summary Compared to standard treatment, the Perception-Action Approach (P-AA) provided similar short-term benefits to infants with congenital muscular torticollis. The P-AA group participants demonstrated higher symmetry and behavior scores, which needs to be confirmed in a larger future study. [ABSTRACT FROM AUTHOR]
