I looked at the Neurolumen site to find out more about it.
I wish those sites would have more information about the product and how it works..
Seems like they just give the smallest amount of info..
basically it looks to be a combo of TENS & LED with a single low level laser diode on the pad. I think it was 4 of the LEDs.
I don't know the cost of this Neurolumen, but to compare..
My Light Relief has 59 colored and infrared light emitting diodes. 65.00 on Amazon
My Digital IF stim device similar to a TENS only better for my soft tissue discomfort. 127.00 or so
TENS is more a pain blocker, so make work better for some.
Chiropractor's low level laser had probably 5-10 diodes. It worked great on those specific sore spots. 1500.00 - 3500.00 for most soft lasers (aka cold, low level)
I just don't know if the Neurolumen has enough lasers or LEDS to have any real impact so basically it is a TENS..
But I could be mistaken...
If you can get a free trial period, it might be worth trying it.
