Electrical stimulation, also known as e-stim, works by sending electrical pulses through your body to help revitalize damaged muscles and diminish pain. E-stim is painless and can help you quickly recover from an injury as well as reduce or eliminate uncomfortable aches and pains.
The electrical pulses sent by the EMS act as a copy of neuron signals, causing your muscles to contract. This results in an increased blood flow through the injured area and promotes the healing and strengthening of the affected muscle.
