Searching for Biofeedback device
Not sure really, but it may have been EngMac . See if you can find some of his posts.
I am a biofeedback provider in Vancouver, British Columbia and you would need temperature biofeedback if you are trying to target the cold hands & feet secondary Raynauds symptoms. If you wanted to target fecal incontinance, then a rectal probe biofeedback unit would be more appropriate. If it’s gastrointestinal, then an EEG biofeedback would best Target it places over the sensory motor strip.
You are best attending a skilled professional who has explicitly used as many of these forms of biofeedback as possible rather than trying to buy the device and figure it out on your own. Some clinicians will have home training units as I do. However, results are improved based on the clinical expertise of the individual. If they lack experience & the success in treating similar cases, then you may find achieving positive outcomes more challenging.
The reality is it’s not a common disease. So few professionals will be well versed in the protocol. Most will need to look it up.
