Brief Summary:
This study compares the effect of adjuvant treatment of Low-level Light Therapy with conventional treatment in the tissue repair of venous ulcers in patients undergoing outpatient nursing consultation. For the evaluation of the cases clinical indicators of Nursing Outcomes Classification have been used.

Condition or disease Intervention/treatment Phase
Venous Ulcer Low-Level Light Therapy Procedure: Low-level Light Therapy Combination Product: Conventional treatment Not Applicable

Detailed Description:

There are several therapeutics with different mechanisms of action to reach tissue repair.

The conventional treatment of venous ulcers is based on the alternation of exercising the lower extremities with resting, the application of topical treatments associated with compressive therapy, and the use of medications.

Despite the diversity of bandages available, there are still lesions with difficult prolonged healing process. Therefore, Low-level Light Therapy has been used as an adjuvant technological alternative therapy, due to its photochemical effects on the tissues, such as the modulation of inflammation, increase of granulation tissue, contraction of the wound, reduction of the inflammatory process, and reduction of pain. This therapy contributes to accelerate and improve the tissue repair process.

Studies assessed by Nursing Outcomes Classification about the usage of the treatments above combined are not available. Consequently, more robust clinical studies over venous ulcers to evaluate the tissue repair must be proposed using reliable instruments.

Primary Outcome Measures :
  1. Decreased Wound Size and Scar formation [ Time Frame: 16 weeks ]

    NOC Wound Healing: Second Intention - Greater length (in the cephalopheudial direction) versus greater width, in cm2 evaluated by the Likert scale, being 1 the worst score and 5 best score.

    NOC Wound Healing: Second Intention - Wound covered with epithelial tissue (new pink or bright tissue that develops from the edges or as "islands" on the surface of the lesion) evaluated by the Likert scale, being 1 the worst score and 5 best score.



Secondary Outcome Measures :
  1. Skin thickness [ Time Frame: 16 weeks ]
    NOC Tissue Integrity: Skin and Mucous Membranes - Depth reached. It involves layers and structures of the skin altered by loss of tissue integrity (ulcerated area) assessed by the Likert scale, being 1 the worst score and 5 best score.

  2. Evaluation of Pain [ Time Frame: 16 weeks ]
    NOC Tissue Integrity: Skin and Mucous Membranes - Unpleasant sensory and emotional experience arising from actual or potential or described tissue injury, with sudden or slow onset of mild to severe intensity, constant or recurrent, without an anticipated or predictable termination. Evaluated as frequency, condition and intensity by the Likert scale, being 1 the worst score and 5 best score.

  3. Overall improvement of other NOC indicators correlated. [ Time Frame: 16 weeks ]
    Overall improvement of the indicators of NOC results of Wound Healing: Second Intention and Tissue Integrity: Skin and Mucous Membranes.
