Guest guest Posted December 17, 2009 Report Share Posted December 17, 2009 Has anyone out there used LLLT directly on the brain or brainstem for either stroke or TBI? Thanks!

Pp. 458–466 Effects of Power Densities, Continuous and Pulse Frequencies, and Number of Sessions of Low-Level Laser Therapy on Intact Rat Brain SANJA ILIC, M.D., SANDRA LEICHLITER, M.Sc., JACKSON STREETER, M.D., AMIR ORON, M.D., LUIS DETABOADA, M.S.E.E., and URI ORON, Ph.D. ABSTRACT Objective: The aim of the present study was to investigate the possible short- and long-term adverse neurological effects of low-level laser therapy (LLLT) given at different power densities, frequencies, and modalities on the intact rat brain. Background Data: LLLT has been shown to modulate biological processes depending on power density, wavelength, and frequency. To date, few well-controlled safety studies on LLLT are available. Methods: One hundred and eighteen rats were used in the study. Diode laser (808 nm, wavelength) was used to deliver power densities of 7.5, 75, and 750 mW/cm2 transcranially to the brain cortex of mature rats, in either continuous wave (CW) or pulse (Pu) modes. Multiple doses of 7.5 mW/cm2 were also applied. Standard neurological examination of the rats was performed during the follow-up periods after laser irradiation. Histology was performed at light and electron microscopy levels. Results: Both the scores from standard neurological tests and the histopathological examination indicated that there was no long-term difference between lasertreated and control groups up to 70 days post-treatment. The only rats showing an adverse neurological effect were those in the 750 mW/cm2 (about 100-fold optimal dose), CW mode group. In Pu mode, there was much less heating, and no tissue damage was noted. Conclusion: Long-term safety tests lasting 30 and 70 days at optimal 10_ and 100_ doses, as well as at multiple doses at the same power densities, indicate that the tested laser energy doses are safe under this treatment regime. Neurological deficits and histopathological damage to 750 mW/cm2 CW laser irradiation are attributed to thermal damage and not due to tissue–photon interactions.

Guest guest Posted December 17, 2009 Report Share Posted December 17, 2009 I wouldn't. I am conservative in my approach with certain things but if I do not know what effect I am having on a tissue I don't believe in doing experimental treatment on the patient - human or canine. We typically do not apply any modalities directly to the brain or spinal cord in traditional therapy.

Guest guest Posted December 17, 2009 Report Share Posted December 17, 2009 Liz, " Has anyone out there used LLLT directly on the brain or brainstem for either stroke or TBI? Thanks! Is this something that you see alot of? How is the diagnosis of stroke being made in your patient? I am just interested, not something that I recognize and only occasionally think about, however I could very well be missing them. What are some of the clinical signs in your stroke patients? Mark, " re-integration of neural pathways " Could you explain? " but I do see where it would help and certainly not hurt " How do you know?

Liz Powers, MPT, CCRT Power Dog Rehab 123 Hawley St. #8 Northampton, MA 01060 yes. I have. remember people, this is not typical laser therapy. this is an FDA approved device for humans. the way it works is totally different. re-integration of neural pathways, healing of tissue, reducing inflammation etc are all ways that it works. now.........would I say I had " miracles " with it..........can't say, as certainly that is not the only therapy I used at the time.. but I do see where it would help and certainly not hurt dr mark newkirk nj 1 of 1 File(s) winmail.dat Quote Link to comment Share on other sites More sharing options...
