poulsp,

There are plenty of posts about LENS. Do a search for LENS.

If you have plenty of money to spend, you may want to try it. If you do not have money to throw away, LENS is probably not a good investment. When Len Ochs, the inventor of LENS is willing to publish the research and research methodology, I may give LENS a better review. So far, he is the only one promoting LENS. It is not FDA approved for treating mTBI, PCS, PTSD, etc.

Some clinicians promote LENS for almost every condition of the nervous system, including fibromyalgia. When a device or therapy is so over promoted, i get skeptical.

You may want to look into volitional neurofeedback. It is a therapy where you are taught to increase some brain wave forms and decrease other wave forms.

LENS, ROSHI, and EMDR are non-volitional neurotherapies. They use external stimuli to try to reprogram your brain.

Hope this helps.

btw, What symptoms are you struggling with that you hope LENS will help?

It is best with PCS, etc to work with each symptoms individually.

My best to you.
