The underutilization of electrodiagnostic and electrotherapeutic tools has far-reaching consequences, impacting diagnostic accuracy, treatment outcomes, healthcare costs, and patient satisfaction. These issues are often rooted in inadequate training, insufficient physician awareness, and challenges in integrating complex technologies. Underuse compromises diagnostic precision, delays treatment, and limits the potential benefits of advanced therapies, leading to suboptimal management of a wide range of conditions. Additionally, the financial burden of underutilized equipment manifests through reduced facility return on investment, operational inefficiencies, and a decline in healthcare services overall quality and sustainability. Addressing this issue requires a multifaceted approach, emphasizing improved training, physician education, and seamless integration of technologies across specialties. Increased utilization can enhance patient outcomes, streamline operations, and ensure the financial viability of healthcare facilities. The purpose of this review is to highlight implications of underutilization while providing a detailed overview of available electrodiagnostic and electrotherapeutic tools across medical specialties, emphasizing the need for enhanced awareness, training, and integration to optimize their use in clinical practice.
