Terraquant Mode # 4 is pre-set for Skin and Wound Care Applications. Treatment is initiated by pressing the button number 4 on the device panel and holding the emitter at the area of the body. The procedures can be performed once or twice daily.
Each treatment procedure takes 5 to 15 minutes.

Scientific Evidence:

Summary of scientific and clinical evidence in wound management using Terraquant™ Laser prepared by Prof Rémy Guibert, MD MSc.

The clinical trials reported in this section have sound methodologies, at least a control group and all have been published in peer review scientific journals.

LLLT produced in vitro increases in cell growth of 140—200% in mouse-derived fibroblasts, rat-derived osteoblasts and rat-derived skeletal muscle cells, and increased by 155—171% growth of normal human epithelial cells. Wound size decreased up to 36% in conjunction with hyperbaric oxygen HBO in ischemic rat models. LLLT produced improvement of greater than 40% in musculoskeletal training injuries, and decreased wound healing time. LLLT reduced by 47% pain of children suffering from oral mucositis.

In vitro, LLLT inhibits bacterial growth of E.coli, Staphylococcus aureus and Pseudomonas aeruginosa.

A randomized double-blind placebo-controlled clinical trial, on thirty consecutive patients with diabetic ulcers or gangrenes and elevated levels of glycosylated hemoglobin, has demonstrated an increase in skin microcirculation due to LLLT, which was an athermic effect, in patients with diabetic microangiopathy. A clinical trial of LLLT, with the combined use of HBO, showed 81% healing of diabetic foot ulcers in patients who previously did not respond to a comprehensive treatment program. The authors conclude that this modality is safe, simple and inexpensive.

A placebo-controlled clinical trial, studying the efficacy of combined phototherapy with LLLT in the management of venous ulceration when used in conjunction with standardized nursing intervention, showed clinical difference in wound healing rate and a continued reduction in wound size at post-irradiation. A double-blind, placebo-controlled clinical trial of low energy photon therapy (LEPT)(Red and Infrared) in venous leg ulcers showed a decrease in ulcer area (compared to baseline) of 193.0 mm2 in the LEPT group and of 14.7 mm2 in the placebo group respectively
(P = 0.0002).

A randomized, controlled study examined the effects of infrared and red pulsed monochromatic light with varied pulsations and wavelengths, in addition to standard treatment, on the healing of pressure ulcers. Patients treated with pulsed monochromatic light had a 49% higher ulcer healing rate, their mean ulcer area was reduced to 10% after 5 weeks compared with 9 weeks for the controls.

A controlled clinical trial of patients with two pressure ulcers (one for polarized light, one as control) examined the effect of polarized light on pressure ulcers of 1st, 2nd and 3rd grades. Pressure ulcers subjected to extra treatment with polarized light in the early stages showed significantly greater improvement in the healing process than the control ulcers.

Pulsed high-frequency, high peak power electromagnetic energy has been shown to increased healing time in patients with Stage II ulcers unhealed within three to 12 weeks and those with Stage III ulcers unhealed within eight to 168 weeks by conventional methods. Stage II ulcers healed in one to six weeks (mean 2.33) and all Stage III ulcers healed in one to 22 weeks (mean 8.85).
