Hi

That looks a good resource, Esther. Here is another resource put out by the Hunter Area Health Service, NSW, Australia:

Bed Mobility with Patient - HNEAHS Internet


Just one comment: If time is of the essence you may be better spent advancing things to sitting up , sitting balance and sitting to standing. Stroke patients often continue to experience some difficulty moving around the bed but this should not preclude them from relearning skills in activities that will get them going.
