Electrical stimulation, often referred to as e-stim, is a therapeutic technique used in physical therapy to stimulate muscles and nerves using small electrical currents. These currents are delivered through electrodes placed on the skin near the affected area. The therapy helps reduce pain, improve muscle strength, promote healing, and enhance circulation. E-stim is commonly used to treat conditions such as muscle weakness, inflammation, chronic pain, and post-surgical recovery. Depending on the settings, it can also assist in retraining muscles to contract properly, especially after injury or surgery.
