Objective: The objective of this review article is to analyze the efficacy and safety of non-surgical electromagnetic and thermal therapies in managing chronic lower back pain. The review will focus on modalities such as short-wave therapy, therapeutic ultrasound, and diathermy, assessing their clinical outcomes and practical implications in treating this prevalent condition. Theoretical Framework: Electromagnetic and thermal therapies represent non-invasive alternatives for treating chronic lower back pain. Diathermy, using electric currents, generates heat that improves circulation and reduces muscle stiffness. Therapeutic ultrasound and short-wave therapy penetrate deep tissues, increasing blood flow and stimulating healing. These modalities are promising options for patients who avoid surgery, reducing pain and enhancing functionality without significant risks. Method: A systematic review was conducted by consulting major scientific databases to identify studies on non-surgical electromagnetic and thermal therapies applied to the treatment of chronic lower back pain. Using specific keywords, recent articles exploring these techniques were collected. This analysis allowed for the consolidation of information on the efficacy of these therapies and highlighted areas needing further investigation, reinforcing evidence-based clinical practice. Results and Discussion: The systematic review shows that non-surgical electromagnetic and thermal therapies are effective in relieving chronic lower back pain, with studies highlighting improvements in pain and functionality. However, variability in treatment protocols underscores the need for standardization to enhance comparability and replicability of results. Further research is essential to elucidate underlying mechanisms and improve clinical practices.
