Abstract: Different regions of the central nervous system activate the neuromuscular system. Nowadays, artificial systems are employed to imitate physiological tasks lost due to neurological injuries. The electrical stimulation of in vivo human tissues, as a way of treatment, has been developed by means of research and technological enhancements. People who have suffered spinal cord injury can lose partial or total motor function. The electrical stimulation of neuromuscular tissue generates artificial movements that can afford long term health improvements by means of neuronal plasticity. Functional electrical stimulation can use diverse parameters, electrodes and application sites in the body. When the adjustments and corrections of stimulatory parameters are performed manually, the system is called open loop control; whereas when it is automatic, the system is closed-loop control. Both ways (open- and closed-loop) contribute to physical rehabilitation of spinal cord injury patients. Closed-loop control systems present advantages in comparison to open-loop systems like automatic correction of electrical stimulation parameters. Therefore, with the development of artificial motor control strategies and the creation of user-friendly interfaces, the activation of software and hardware for producing movements artificially can be performed by the users of the system (spinal cord injury patients), resembling the human physiological system.
