Complex Electrical Stimulation Systems in Motor Function Rehabilitation after Spinal Cord Injury

Table 1

Different stimulation electrodes are compared.

Electrode	Current (mA)	Advantage	Disadvantage
Implantable electrode	<25	High specificity, can be used for a long time	Need surgery, may have inflammation
Nonimplantable electrodes	<120	No surgery required	Not portable, prone to high current discomfort
