E-stim sends mild electrical pulses through the skin to help stimulate injured muscles or manipulate nerves to reduce pain. E-stim may not be appropriate for everyone, but for many people this painless procedure is accelerating recovery and providing relief from painful or uncomfortable symptoms. E-stim uses electrical pulses to mimic the action of signals coming from neurons cells in your nervous system. These mild electrical currents target either muscles or nerves. E-stim therapy for muscle recovery sends signals to targeted muscles to make them contract. Flexing your biceps is a form of muscle contraction.

Types of Electrical Stimulation Used in PT
Reanimation of paralysed facial muscles by electrical stimulation has been studied extensively in animal models, but human studies in this field are largely lacking. Twenty-four subjects with a peripheral facial nerve palsy with a median duration of three years were enrolled. We studied activations of four facial muscles with electrical stimulation using surface electrodes. In subjects whose voluntary movement was severely impaired or completely absent, the electrical stimulation produced a movement that was greater in amplitude compared with the voluntary effort in 10 out of 18 subjects in the frontalis muscle, in 5 out of 14 subjects in the zygomaticus major muscle, and in 3 out of 8 subjects in the orbicularis oris muscle. The electrical stimulation produced a stronger blink in 8 subjects out of 22 compared with their spontaneous blinks.

Electrical muscle stimulation EMS , also known as neuromuscular electrical stimulation NMES or electromyostimulation , is the elicitation of muscle contraction using electric impulses. The electrodes are generally pads that adhere to the skin. The impulses mimic the action potential that comes from the central nervous system , causing the muscles to contract.
If you suffer an injury or illness that results in pain and loss of functional mobility , your doctor may refer you to physical therapy. Your physical therapist will likely work with you to improve your ability to function, and he or she may use various therapeutic modalities to augment your rehabilitation program. Electrical stimulation is a type of therapeutic treatment that can serve many different purposes in physical therapy. Electrical stimulation often is used to augment your physical therapy program after an injury or illness; it should not be the only treatment you receive when attending physical therapy. This list of different types of electrical stimulation can help you understand how it is commonly used in physical therapy.
