The Effect of Combined 650 nm and Infrared Laser on Chronic Diabetic Foot Ulcer Surface Area:

The Effect of Combined 650 nm and Infrared Laser on Chronic Diabetic Foot Ulcer Surface Area: a Randomized Controlled Trial

Objective: investigate the effect of combined 650 nm and infrared laser on chronic diabetic foot ulcer surface area.

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

Objective: investigate the effect of combined 650 nm and infrared laser on chronic diabetic foot ulcer surface area.

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 days needed for surface area reduction before and after receiving the treatment protocol for two consequetive months, and the secondary outcomes were % of wound cause and location frequencies

Inclusion Criteria:

• 1- Diabetic patients with either type I or II 2- Age from 18-60 years old, both sexes 3- Ulcer lasting longer than two months 4- DFU grade 1 or 2 according to Wagner classification. 5- All patients able to walk dependently

Exclusion Criteria:

1. Patients with vascular disease
2. Patients with fixed ankle deformity as Charcot foot or stiffness
3. Patients with any type of osteomyelitis associated with DFU
4. Patients with renal or hepatic failure
5. BMI < 30 kg/m2 as Obesity can cause poor perfusion due to vascular insufficiencies; altered population of immune mediators may lengthen the inflammatory process & decrease oxygenation of subcutaneous adipose tissue which is liable to be infected.
