Electrostimulation is a technique that uses electrical impulses to stimulate muscles or nerves. This method can help in rehabilitation, pain relief, and muscle strengthening. It is often used in physical therapy settings to aid recovery after injuries or surgeries. Devices that provide electrostimulation, such as TENS units (Transcutaneous Electrical Nerve Stimulation) and EMS devices (Electrical Muscle Stimulation), deliver controlled electrical signals. These signals mimic the natural impulses sent by the nervous system, promoting muscle contraction and improving blood circulation.
