Wound Healing, LED array

Near IR light makes wounds heal faster
LED arrays at 660 nm seem to be the favourite
NASA found that wounds heal slower in microgravity, they seem to have done the best research.
Red LED arrays are carried on Space Shuttles and Nuclear submarines. This doesnt absolutely rule out 'woo factor' but these are serious space constrained situations.
Lacking LED arrays, I sometimes use an ordinary incandescant light bulb up close, but this may have a burning effect.
I dont know if NZ medecine uses this therapy

Abstract
A case of 75-year-old male patient with a non-healing ulcer over left sole is reported. Patient was a known diabetic with CCF. The ulcer was not healing for one month with routine treatment. The patient was given BIOBEAM 660 therapy every alternate days for a month which led to .

Abstract ackground and aims. Blepharoplasties can be associated with sequelae-related patient downtime, often extended or reinforced by periocular laser ablative resurfacing. The present controlled study examined the effects of a new-generation LED phototherapy system on enhancing wound healing following such combination surgery.

Methods. Two males and eight females participated in the trial, with ages ranging from 44 to 59 years (average 52.3 years). Following blepharoplasty and Er:YAG/CO2 laser ablative resurfacing, one-half of each subject's face was treated with the red LED therapy (20 min, 96 J/cm2, 633 nm), the contralateral half being the unirradiated control. Patients reported subjectively on pain levels and resolution. Resolution of erythema, edema, bruising and days to healing were independently evaluated from the clinical photography. All findings were compared between the treated and untreated sides.

Results. In all instances, the LED therapy-treated side was statistically significantly superior to the unirradiated control by a factor of two to three.

Conclusions. In this small series of 10 patients, red LED phototherapy after blepharoplasty and laser ablative resurfacing cut the time to resolution of side effects and the healing time by one-half to one-third compared with contralateral unirradiated controls.

56 LED array 660nm (red) 4000 mcd brightness.
Includes 110v AC adaptor (220-240v $10. Indicate at checkout) Array approx. 3/4"x2"x3" $94.95

660nm (red) LED light speeds healing of wounds, infections, and other conditions to a depth of about 1" by increasing cellular ATP and energy while reducing pain. Research indicates that red light kills the bacteria that cause tooth decay and some abcesses.

NASA LED’s have proven to stimulate wound healing at near-infrared wavelengths of 680, 730 and 880 nm in laboratory animals, and have been approved by the U.S. Food and Drug Administration (FDA) for human trials. Furthermore, near-infrared LED light has quintupled the growth of fibroblasts and muscle cells in tissue culture. The NASA LED arrays are light enough and mobile enough to have already flown on the Space Shuttle numerous times

at the University of Chicago, researchers discovered that the average wavelength of cell tissue in the human body ranged between 600 nanometers and 720 nm; 660 is the mid-point. So in essence, the reason a 660 nm works better than any other single frequency is because it is closer to the resonant frequency of cell tissue.

the essential basic light unit should contain a 660 nanometer red LED of 4,000 - 6,000 milli-candles with both a continuous and a 250 pulse-per-second light beam selector.

An LED array is currently on board a US Navy nuclear submarine for treatment of potential training injuries. Dr. Whelan is a commander in the Navy and a diving medical officer for the Naval Special Warfare Command, which includes the SEAL (Sea, Air and Land) teams. Dr. Whelan has been inducted into the NASA Space Technology Hall of Fame for his research into the use of LEDs for wound healing and the treatment of brain tumors.

To study 670-nm light effects on incisional injury, animals were left unexposed or exposed to equal doses of high-, medium-, or low-flux light. Burn injuries were treated with high-flux light or left unexposed. Healing was assessed by measurement of the burn area and the gap remaining to closure of incisional injury.
RESULTS Mice exposed to 670-nm red light showed significantly faster healing than control mice. High, medium, and low fluxes of light were all effective after incisional injury. In burn injury, there was improvement in wound healing initially, but the time to repair was unchanged.
CONCLUSIONS A 670-nm LED red light source accelerates healing in skin of SKH-1 hairless mice after incisional injuries, but is not as effective for burn injuries. These data that suggest red light exposure may be helpful in postoperative wound repair.
