I think it's a psych thing - intended to break the subconscious/psychological link between activity & symptoms - comes from operant conditioning theory.??? I think??? I sure I read Ellen Goudsmit explaining about it ages ago but I not good at explaining. Something like if you do the same every day but your symptoms still fluctuate (their theory goes) then it will break the link in your mind that activity = symptoms.
perhaps
@Joan Crawford could explain that better, or correct me.
@PhysiosforME the podcast is ace well done
That's what CBT/GET for CFS is aiming to do. You explain it spot on.
CBT/GET for CFS is aiming to 'help' the patient to break the cycle between symptoms (these they believe you have been conditioned to (over) react to through experience - rather than disease/bodily dysfunction process) and then experiential learning.
So, for example, if they can 'encourage' patients to be more active (via CBT/GET methods) then their therapy holds that patients will gently learn over time that they had nothing to fear. Essentially, patients can be deconditioned / have their fear(s) extinguished - in a systematic and progressively more ambitious program of increasing activity and decoupling from symptoms - in a similar way to how phobias are treated. Basically: they think patients' fear of activity along with excessive symptom focusing keeps patients disabled/trapped. In their heads symptoms are all self generated from within / are the patient misinterpreting benign bodily sensations / overly focused on minor symptom and so forth. There is no room of biological issues, not even a nod to physical possibilities, dysfunction, disregulation, disease.
If all that above were true, then imo, CFS or MUS would be fabulously straightforward to treat.
But alas, they (CBT/GET for CFS friendly folks) present no such convincing evidence that what they propose works - either theoretically or empirically.
It occurs to me that the CBT/GET for CFS/MUS crowd have a very narrow focus (perhaps this is common in academia - I don't know - I have no experience here but I tend to think many academics work well collaboratively......) - But it clear that 'it' is determined to succeed - in spite of contradictory evidence. It's a closed shop of researchers with perhaps a lot of group-think. Lots of ugly in-group; out-group dynamics. And, of course, then lots of fear and cognitive dissonance - that they might actually be rather barking up the wrong tree. So, they vent that anger/fear back at patients; people who won't believe them (other researchers) and so forth - hence the thin skin to being heckled transmuting into 'threats' by patients.
When objective measures of activity are used e.g. Black, O'Connor & McCully (2005): "Overall mood and muscle pain worsened in the CFS patients with increased activity." That objective evidence matches patients experience - time and again.
I/we have no idea what patients actually do in CBT/GET trials as patients have not been monitored objectively: during, pre or post. Nor has anyone to my knowledge defined / operationalised deconditioning and demonstrated objectively that pwME are deconditioned pre CBT/GET for CFS and then not deconditioned post therapy. That 'should' all be easy to do if they were talking about observable concepts.
So much that could be done to demonstrate their theories and ideas are good proposition / sound - but alas so much avoided.
