Sit upright on a stable chair or wheelchair with your back supported and a table close in front at elbow height.
Ensure both feet are placed flat.
Place your elbows onto the table.
Interlink your fingers, placing your palms together to make a pyramid with your forearms.
Ensure your wrists are as straight as possible
Keeping your palms together, twist your hands so that the back of one hand faces you, then again so the back of the other hand faces you.
Move your elbows closer together to allow more movement.
Do not force your wrists.
