Electrical stimulation (ES)

Electrical stimulation is a clinical procedure and therapeutic modality that involves the application of controlled electrical currents to specific tissues, most commonly nerves and muscles. It functions by generating an electric field that alters the resting membrane potential of excitable cells, leading to the initiation of action potentials and subsequent physiological effects such as muscle contraction or sensory modulation. While it is a cornerstone of physical therapy, cardiology, and neurosurgery, electrical stimulation is not a molecule, receptor, or enzyme, and therefore does not qualify as a traditional molecular therapeutic target. Instead, it is a physical intervention used to treat conditions ranging from chronic neuropathic pain and muscle atrophy to cardiac arrhythmias and movement disorders. In a pharmaceutical context, it is often studied as a non-pharmacological alternative or an adjunct therapy that interacts with endogenous systems like voltage-gated ion channels.

Application of external electric fields to biological tissues to induce the movement of ions across cell membranes, typically activating voltage-gated ion channels to trigger action potentials in neurons or myocytes.
