what is normal cervical lateral flexion for infants
Abstract. Purpose: To determine reference values for cervical range of motion (ROM) in rotation and lateral flexion and for muscle function in the lateral neck flexors in a sample of infants who were healthy. Method: ROM was measured, and muscle function was estimated in 38 infants at the ages of 2, 4, 6, and 10 months.nfants of 2 months of age had a median muscle function score of 1 (interquartile range, 1â2). Muscle function increased to score 3 to 4 by 10 months. Conclusion: Infants below 1 year of age have good ROM in rotation (â¥100Â°) and lateral flexion (â¥65Â°) of the neck.
