DPN not only leads to hospitalizations but significantly impacts the quality of life due to painful symptoms. Traditional treatments focus on symptomatic relief, often failing to address the underlying neuropathy. This study aims to explore the effects of Low Level Laser Therapy (LLLT) as a potential game-changer in the treatment of painful DPN in T2DM patients.

Materials and Methods:

In this pre-post observational study, 19 T2DM subjects with confirmed peripheral neuropathy underwent Low Level Laser Therapy. After ethical clearance and informed consent, subjects were evaluated using the Michigan Neuropathy Screening Instrument (MNSI), pain scales, and biochemical parameters. The therapy involved a specific dosage of laser irradiation over a period of 10 days, with assessments conducted pre and post-treatment to gauge effectiveness.


The results were significant and promising. Patients showed a substantial reduction in pain, as measured by the Visual Analogue Scale (VAS), and improvements in MNSI scores. Additionally, there was a notable decrease in vibration perception threshold and an increase in foot temperature, indicating improved microcirculation.


The study concludes that Low Level Laser Therapy is an effective intervention for reducing pain in T2DM patients suffering from peripheral neuropathy. This non-invasive method shows potential not only in pain management but also in enhancing the overall quality of life for patients grappling with the debilitating effects of DPN.


Painful DPN, often a result of microvascular injuries and nerve damage, can now be approached with LLLT. The therapy's effectiveness lies in its potential to stimulate microcirculation, enhance nerve regeneration, and subsequently reduce pain. This method stands out as a beacon of hope against the backdrop of traditional treatments that focus more on symptom management rather than addressing the root cause.

In closing, this study sheds light on the effectiveness of Low Level Laser Therapy in managing painful DPN, offering a ray of hope for those suffering from this common diabetic complication. As the prevalence of T2DM continues to soar, such innovative treatments become vital in the quest for improved patient care and quality of life.
