YE is a 5 year, 7 month old boy with developmental delay. He had a stroke in infancy, and the right side of his body is affected. He is not able to stand or extend his right arm.

Sitting height measurements (along with weight) are used to monitor YE's growth. He is consistently measured sitting on a 40 cm box.

YE's sitting height measurements parallel those on the stature-for-age charts. Together, with regular weight measurements, his sitting height-for-age measurements indicate that he is growing well.
