Photographic Assessment to Evaluate Effectiveness of Low-Level LASER Therapy in Wound Healing: A Randomized Controlled Trial

Abstract

Introduction: Among the existing non-invasive therapies, Low Level LASER Therapy (LLLT) has been gaining interest as various studies have proved its effectiveness in the treatment of non-healing wounds but no studies have been done to report the effects within a shorter duration when compared to Standard Operating Procedure.

Aims: To evaluate the effectiveness of LLLT on ulcer dimensions using photographic assessment and simple ruler method. To compare effectiveness of Standard Operating Procedure and LLLT on ulcer dimensions using photographic assessment and simple ruler method.

Materials and methods: A randomized controlled trial was carried out on total of 30 subjects divided randomly into 2 groups of 15 each.  Standard operating procedure was given to group A, whereas LLLT along with Standard Operating Procedure was administered to group B. Intervention was given for 6 days. Patients were assessed for ulcer dimensions using a simple ruler method and IMITO Measure app, and pain assessment was done using Visual Analogue Scale pre and post intervention of 6 days.

Results and discussion: Significant improvement in pain reduction was seen in both the groups (p<0.05). But when comparison was done between the groups, no significance was reported (p>0.05). There was no significant difference noted in the ulcer dimensions in both groups (p>0.05).

Conclusion: The study concludes that standard operating procedure is equally beneficial as in combination with LLLT. LLLT can be used in conventional therapy to lessen the pain of the patient.
