An electrical muscle stimulation (EMS) device and a method for using it are disclosed herein. The EMS device includes at least one electrode, a microcontroller, a buffer, a DAC, and an amplifier. The method includes placing at least one electrode in contact with the skin of a patient, performing a diagnostic to determine the soft tissue injury, securing the at least one electrode to the patient, turning on the EMS device, and performing movement protocols. The EMS device transmits pulses to the soft tissue injury using a waveform. The waveform has an alternating polarity.
