I suggest you check locally to see if there is a clinic that offers it. As I said, my PT has used it for over 10 years. Some of the local chiros do it and even advertise it on TV. The systems are sold by infomercials on TV for $600.
Using it for upper cervical injuries sounds great. The use for neurological injury is interesting but I don't think it is approved for such use yet. As I mentioned, the study mentioned earlier this year showed great promise for neuro issues using near infrared wave lengths.
Here is one link:

Maybe someone can post a link to the previous thread about LED light therapy for neuro issues.
