Crossing the midline - A fundamental physical skill

"How are your students getting on with crossing the midline?" asked the schools O.T (Occupational Therapist) as we crossed paths in the school hallway. I looked blankly at her in an awkward fashion. Feeling embarrassed, I said "What do you mean? Their progress at jumping over the middle line in the gymnasium?". Her reaction was priceless!

3 years on and I am so grateful for bumping into the conversation. I used this opportunity to go away to investigate and explore what she really meant. It has made me into a greater physical educator with a more expansive understanding of young children's movement requirements.

What is 'Crossing the midline'?

Imagine a line running from the top of your head to the middle point between your 2 legs as low as your toes - this is the midline.

The midline

Crossing the midline refers to a persons ability to reach their arms or legs across the middle of the body over to the opposite side. Crossing the midline is an important developmental skill.

How can I spot difficulties?

Learners may show the following if they are having difficulties with crossing the midline: - Swap hands midway through drawing, painting, colouring or writing across a page. - Use the right hand for activities on the right side of the body and left hand for activities on the left hand side. - Avoid crossing the body mid-line. - Find visual tasks such as following text when reading or catching from one side of the body to the other challenging.

- Display poor pencil and handwriting skills. - Have difficulties whilst changing, putting on socks and tying shoelaces. - Show difficulty coordinating gross motor patterns (e.g. crawling, rolling, side stepping, jumping jacks).
