Question
What is meant by symmetry in movement presentation, and is it required for a 4-month-old baby to have consistent movements?
Answer
Children in normal conditions do not need to worry about this. The principle of movement symmetry refers to executing actions in the most effective way to achieve the best results. Movements in a single direction may cause the body’s center of gravity to shift, increasing fatigue. In contrast, symmetrical actions performed by both hands in opposite directions are the most energy-saving method.
