In backward chaining you get the patient to go in stages from standing to lying and back up again. The theory is that if they can get themselves down, they can get themselves back up again. So you start by getting the patient to go from sitting to kneeling and then back to sitting, then sitting to kneeling to sitting on the floor and back again, the sitting to kneeling to sitting on the floor to lying and back.
What you need to do is try and get hold of a sheet which explains it better than I can really. I've not seen it in practice (tho we did learn a little about it in a prac session once) but I started a neuro placement today and they teach backward chaining in falls class which I'll hopefully get to see. Any new info about it and I'll post it on here.
Meanwhile, anyone know much about "positive support reactions" saw a guy with one today, apparently they are quite rare really. Is it as simple as them getting their foot "stuck" to the floor and being unable to unlock their knee??
