Study summary

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

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.

Study arms

  • Experimental
    laser sequential mode

    All patients received 2 sessions of laser therapy / week with different wavelengths in sequential mode in two consecutive months of treatment aiming complete wound closure , patients received \& infrared laser therapy plus traditional wound care

    Device: laser therapy

  • Experimental
    laser seperate mode

    All patients received 2 sessions of laser therapy / week with different wavelengths in seperate mode in two consecutive months of treatment aiming complete wound closure , patients received \& infrared laser therapy plus traditional wound care

    Device: laser therapy

  • Active comparator
    traditional wound care

    (II) Traditional wound care inform of 1. Wound care treatment * Debridement to remove necrotic tissue * Irrigation of the wound by normal saline * Change dressing daily to protect wound from infection 2. Foot care * Wash feet daily, dry carefully especially between toe * Avoid extreme temperatures * Inspection daily of foot blisters 3. Foot wear * Avoid walking bare foot * Properly fitted shoes * Avoid wearing open-toed shoes

    Device: laser therapy

Interventions

  • Devicelaser therapy

    All patients received 2 sessions of laser therapy / week in two consecutive months of treatment aiming complete wound closure , patients received \& infrared laser therapy plus traditional wound care: (I) Use red \& infrared laser therapy device with 4 different wavelengths in a synchronized mode: 1. 980 nm for wound decontamination, improve circulation, lymphatic drainage 2. 915 nm enhances O2 delivery 3. 810 nm increases ATP production 4. 650 nm accelerate surface healing, tissue regeneration plus traditional wound treatment mentioned before

What researchers measure

Primary outcomes

  1. percent of wound size measurement methods

    weekly by 1. a ruler (wound area was calculated by measuring and multiplying the greatest length by the greatest width perpendicular to the greatest length) 2. a sterile transparent film sheet

    Time frame: two consecutive months

  2. percent of wounds complete closure

    measure percent of wounds complete closure in each group

    Time frame: two consecutive months

Secondary outcomes

  1. percent of each type of wound cause

    different wound cause diabetic foot ulcers and healing time

    Time frame: two consecutive months

  2. percent of each wound location

    different wound location in diabetic foot ulcers and healing time

    Time frame: two consecutive months

  3. percent of days needed for surface area reduction

    measure the days needed to decrease surface area in each group

    Time frame: two consecutive months
