It depends on your goals and what you consider technology.
- Biofeedback: Fairly broad field some with excellent clinical evidence, other without. Used mainly for anxiety, PTSD, ADD and the spectrum, and sometimes for addictions depending on the device.
There are some options for home use from fairly cheap and decent to outright expensive but with clinical results remotely (meaning you stay at home and the info goes to an actual Doctor or therapist).
All prices in USD (US Dollar $)
a) BrainTap : est $ 800 (some swear by it others say meh)
b) FocusCalm : est $ 400 (many athletes, traders and poker players swear by it)
c) NeurOptimal : Est $ 6,000 to $ 10,000 for one person. (Clinical quality results for some pretty serious issues, including serious addiction. But obviously quite expensive.)
- Theta Chamber : Est $ 80,000. A pod using multiple modalities (binaural, light (similar to BrainTap but more advanced); electrodes on your ear lobes; and it spins at about 15rpm which makes you feel as though you are floating) that bring you to a theta state similar to a float tank but without the water. Has had excellent results in many areas. Has been around since the late 1980’s.
What you’ll quickly find is that many of these technologies are focusing on stress, anxiety etc. Many get expensive fairly quickly. Some are reserved for millionaires or clinics.
There are other technologies but I just wanted to move your thread along and get it started to see if other people throw out ideas.
I will say this though, with AI in the next few years, literally in the next 5, we might be seeing some new technology. Who knows.
