Tilt training is supposed to help. I can't vouch for it - it's on my to do list
- maintain that position for up to 30 minutes
- try to do two sessions each day.
Note: this is
very unpleasant. Don't do it on your own if you think there is any possibility that you might faint.
Sounds great for people who don't have ME - early fainting is the best outcome you could hope for if you do (but you probably won't) - instead damage to the heart, brainstem etc and permanent severe disability and loss of ability to stand, at best inability to do anything else but lie down for the rest of the day which sounds kind of counter-productive. Sufferers can already achieve that sort of diaster by activities of daily living.
Prolonged standing is one of the worst things you can do with ME.
People with ME are already doing as much as they can, why wouldn't they, to do any more means robbing themselves of some functioning in other aspects to temporarily achieve it. This is why "retraining" won't work - the disability is all pervasive disease process & ongoing injury, not a hit and run & fear avoidance/ deconditioning/ laziness.
PwmE continually report that standing is one of the worst things, often a precursor to becoming severely affected.
Even small excesses of activity which produce no short term bad effect can over weeks build up to cause a crash.
The rehabilitation school keeps pushing the myth that pwME are doing less than possible and that there's a safe "headroom" above them to move incrementally into without exacerbation due to an elastic glass ceiling, if only that were true. In reality they have next to zero understanding of the exercise pathology of ME because even the knowledgable people don't know that much, it's all about ideology and hubris.
The GET studies have very poor results (a big fat nothing if you include objective measurements of fitness and return to work [i.e. significant "recovery" in most people's dictionary) and that's with non-severely affected patients.
Best to look at the disease processes and ignore this sort of misleading messiah complex rehab school crapola for what it is.
