Hi Wullie,
How about trying to use these little standing and clapping breaks as a therapeutic possibility.
How about...
trying to get her to klap on her knees.. or stamp with her feet in conjunction with her clapping...
or... swaying with her bodyweight during the clapping...
or... lifting her legs (kicking?) during clapping.
... maybe even putting music on and using steps to get her to clap and stand on a step at the same time...
... try dancing with her...instead of walking...
Try to turn what she wants to do (which could be because of stamina problems and her wanting to get her breath back and yes I certainly recognise this type of behaviour) into something therapeutic.
I wish you both well
Esther
