Objective: investigate The effect of combined red and infrared lasers on histopathology collagen formation in diabetic foot ulcer Participants: The forty five patients will assigned randomly into three equal groups, each group consist of 15 patients, group A received laser therapy in sequential mode, group B received laser therapy in separate mode and the control group C receive conventional wound care treatment

Objective: investigate The effect of combined red and infrared lasers on histopathology collagen formation in diabetic foot ulcer Participants: The forty five patients will assigned randomly into three equal groups, each group consist of 15 patients, group A received laser therapy in sequential mode, group B received laser therapy in separate mode and the control group C receive traditional wound care Outcomes: the primary outcomes were the wound surface area measurement, % of wound complete closure and % of collage formation before and after receiving the treatment protocol for two consequetive months

Inclusion Criteria:

• aged between 18 and 60 years; both gender; Diabetic patients type II; Ulcer lasting longer than two months; diabetic foot ulcer (DFU) grade 1 (Superficial diabetic ulcer, ulcer limited to the dermis, not extending to the subcutis) or grade 2 (Ulcer of the skin extending through the subcutis with exposed tendon or bone and without osteomyelitis or abscess formation) according to the Wagner classification

Exclusion Criteria:

• Patients with fixed ankle deformity as Charcot foot or stiffness; Patients with any type of osteomyelitis associated with DFU; the presence of active infection requiring hospitalization, gangrene, systemic diseases such as collagen-vascular diseases, renal failure, evidence of ischemia; BMI < 30 kg/m2 as Obesity can cause poor perfusion due to vascular insufficiencies; an altered population of immune mediators may lengthen the inflammatory process & decrease oxygenation of subcutaneous adipose tissue which is liable to be infected

All collected individual participant data (IPD), all IPD that underline results in a publication.

In the next month of registration.

Information will be available upon request through the following e-mail: heidy.fouad@gmail.com.

the patient didn't know the types of modes of laser applied even in the control group i used light not laser to equalize the blindness
