yes that’s right.
My son has dyspraxia as well as severe dysgraphia (he finds it very hard to write at all, or even use a ruler to draw lines, although he can touchtype). Typically you might have poor fine and/or gross motor control among a lot of other things.
One of the things that can happen is that your body can “forget” how to do things - it was explained to me in layman’s terms as imagining that every action you do is contained in a filing cabinet with its own drawer. The brain goes to that drawer and opens it to perform the action. With dyspraxia, the brain might open the wrong drawer.
My son had very poor motor control, unfortunately making it hard for him be good at or to learn new sports in particular which is a nightmare in this country as we’re big on sport in schools. He would be able to do something (for example, bowl in cricket) and then the next day be quite unable to do so. Which was very frustrating for him.
So Ryan and his bike is something I can relate to and find believable.
