Great overview of NIRS by this group. Ruud thanks for sending me this mail . I knew they where working on an overview but did not had access yet so here for all the read. I like to he article as it tells us , that we are not too much of in practical application and in fact many may still be ahead of the scientific groups.
Here the link .
Now here a nice summary of available equipment and a short cortical look from my side.

There are a few interesting information's or rather missing information's , despite that this was done by an accepted group.
1. There are equipment's on the list which miss any scientific publishes and therefore information to verify the technology and is acceptance.
2. There is minimal points made on possible SmO2 changes due to blood flow reactions lie compression , occlusion's or gravity reactions. This is what we discuss since many weeks in here and show how SmO2 can be influenced there for.
3. If they looked and used and therefore compared all the above equipment than there are at least 2 systems who not just find SmO2 /TSI is in on system but as well tHb.
In fact Portamon actually looks at TSI % and we discussed this already , that there is a difference between SmO 2 and TSI %.
Now interesting enough both Portamon and MOXY have the great ability to actually assess and give you a tHb trend but not mentuo0ned above.
4. On the other side there is a My Nimo product who has tHb mentioned as an option of feedback.
Look at the country it is made and than there may be 2 options.
1 : ????
2. Insufficient information and research from the great group who did this paper.
Which option would you prefer ?( Smile )
