A Comparative Study of Low-Level Laser Therapy and Short-Wave Diathermy in the Management of Peripheral Diabetic Neuropathy of the Lower Extremity

Abstract

Background: Diabetic peripheral neuropathy (DPN) is a common complication of diabetes mellitus, causing pain, numbness, and reduced sensation. Effective management is essential, as pain often disrupts daily functioning and sleep. Pharmacological treatments have side effects, leading to increased interest in non-pharmacological therapies.
Objective: To compare the effectiveness of Low-Level Laser Therapy (LLLT) and Short -Wave Diathermy (SWD) in managing pain and symptoms associated with DPN.
Methods: Two groups were treated with LLLT (Group A) and SWD (Group B). Outcomes were measured using the Numeric Pain Rating Scale (NPRS) and Treatment-Induced Neuropathic Assessment Scale (TNAS 3.0). Statistical analysis (t-tests) compared the effects of the treatments within and between groups.
Results: Both treatments showed significant improvements in pain reduction (NPRS) and neuropathy symptoms (TNAS 3.0). SWD demonstrated significant effect on pain, while LLLT showed for functional improvements.
Conclusion: Both LLLT and SWD are effective for managing DPN, with each offering specific advantages.
