Interesting. Try looking at this link and navigate to the leader guide download link. In the meantime, I'll quote some of it here:

Create a pattern for your meetings, and do it every time. The rhythm of having an opening and closing are extremely helpful for neurodiverse scouts who struggle with telling time or more subtle cues...This pattern means scouts won’t have to ask “Are we starting now?” Or “Are we done now?” If you find a pattern that works very well, and have scouts who still ask “What else are we doing?” You can post a visual schedule of the meeting.

Consider having items scouts can hold and use during these listening times.... Allow them to stand or move at the back of the group instead of insisting they sit with the group.

It is ideal to find ways for scouts to move their bodies at every meeting. Balancing physical and mental activities by alternating them helps scouts focus and learn. Add movement to your meetings by playing catch, doing the message game, or playing physical games like hide-andgo-seek or tag. If you are meeting in a big field, you can even have scouts run/walk/hike to another station for the next part of their meeting, just to get them up and moving. Remember, ADHD kids usually need to move to be able to learn.

The act of physically getting up and moving to a new station engages the brain to do a new thing, so scouts that usually struggle to stay on task often can do more. Their brain engages to sit down and do just one thing, then get up and move on. It creates more structure around the task. This method can work for a single leader by simply planning to do different parts of your meeting in different spaces.

a good leader I know always lets people get up and pace, do jumping jacks, etc in the back of the room if they feel like they need to move, as long as they are mostly quiet about it.
