Preserving the passive and active external rotation range is often reported as a main goal in this population,11 and extension might be considered to be a secondary target. Targeting this direction as well by stretching and strengthening in children with residual strength may improve global shoulder muscle balance, posture, motion, and joint integrity. Future studies are needed to elucidate the relationship among sagittal and transverse strength imbalance, underlying muscle atrophy, and glenohumeral deformities.
