How does the V-Light 810 work?
The near infrared wavelength of 810 nm in this model penetrates more directly and deeper into the brain than the V-Light 655 to reach deeper lying glands. Brain cells respond just as well as other cells in the body to this dosage of light energy.
It is engineered to pulse at 10 Hz, which has been associated with brain oscillation in alpha state. In studies, this has drawn the greatest neurological healing in traumatized brains. This state also helps to release certain calming chemicals in the brain.
In China, intranasal light therapy with low level laser has been used to treat insomnia. Wang et al (2006) treated 50 patients with insomnia with low level laser at 650 nm, powered with 3 mW for 60 minutes per each session per day, over 10 – 14 days. They found that the symptoms improved significantly for 82% of the patients.
MILD COGNITIVE IMPAIRMENT
Jin L et al (2001) randomly divided 93 patients with cerebral infarction into three groups, 30 in a drugs‐only group (A Group), 32 in intranasal low level laser therapy + drugs group (B Group) and 31 in an intravascular low energy laser therapy + drugs group (C Group), and then treated B Group with low level laser at 670 nm and 7 ‐10 mW for 40 min each time and C Group with He‐Ne (632.8 nm) laser at 1.5 mW for 90 min each time, once daily for ten days. They found a decrease in the peak latency potential of the P300 waveform, and greater erythrocyte deformity after the treatment in either B or C Groups than A
Xu C et al (2002) divided the objects into two groups, 47 patients with Alzheimer’s disease (AD) and 22 patients with gastric ulcer, and treated the patients with intranasal low level laser therapy with He‐Ne source at 3.5 ‐ 4.5 mW for 30 minutes each time, which was done once every morning for 30 days. They found that melatonin, score in mini‐mental state exam (MMSE) and score in Wechsler memory scale for adult (WMS) increased in the AD group, but there was no significant change for the gastric ulcer group.
Li Q et al (1998) treated 43 patients with Parkinson’s disease (PD) with intranasal low level He‐Ne laser therapy at 3.5 ‐ 5.5 mW for 30 minutes per treatment session per day for ten days, and found serum cholecystokinin‐ octapeptide (CCK‐8 ‐ which high levels have a deleterious effect on cognitive ability in PD)4 decreased to normal levels. When referencing to Webster Scale scores (WSS), they found the improvements to be significant for 26 of the 43 patients.
Xu C et al (2003), treated 47 patients with PD with intranasal low level He‐Ne laser therapy at 3.5 to 4.5 mW for 30 minutes per session, every morning for 20 days, and found the PD symptoms improved for 31 (66%) of the patients. Out of these, 14 (29.8%) were significant while 27 (57.4%) were mild. Presence of superoxidase dismutase (SOD) and melatonin increased and malondialdehyde (MDA – a marker for oxidative stress) decreased.
Zhao G et al (2003) treated 36 patients with PD with intranasal low level He‐Ne laser therapy at 3.5 ‐ 5.5 mW for 30 minutes per session per day for ten days, and found improvements in PD symptoms for 31 (89.1%) of the patients; out of whom 10 (27.8%) of them were significant and 21 (58.35) mild.
Liao Z et al (2000) randomly divided 80 patients with schizophrenia into two groups, 40 in drugs‐only group (A Group) and 40 in intranasal low level He‐Ne laser therapy +drugs group (B Group). The B Group was treated with energy of 2 mW for 60 minutes per session per day for ten days. They found that significant improvement was achieved more quickly with the B Group ‐ on the 18th day versus the 26th day for the A Group.
MIGRAINE AND HEADACHES
Li Q et al (1998) treated 39 patients with chronic headache, migraine and trigeminal neuralgia with intranasal low level He‐Ne laser therapy at 3.5 ‐ 4.5 mW for 30 minutes per session per day over two 5‐day sessions with a 2‐day break in between. They found improvements in 35 (89.8%) of the patients, out of whom 26(66.7%) were significant. The blood β endorphin in the blood of the 35 improved patients was also found to have increased.
STROKE (CEREBRAL INFARCTION)
Qiao Y et al (2004) treated 68 patients with cerebral infarction with intranasal low level He‐Ne laser therapy at 10 ‐ 15 mW for 60 minutes per session per day over 10 days. The more severe cases had 3 sessions per day. They found improvements in 61 (89.7%) of the cases, out of which 34 (50.0%) were significant.
