Transcranial Direct Current Stimulation Versus Virtual Reality on Gait in Children With Spastic Diplegia

"Transcranial direct-current stimulation (tDCS), over the motor cortex, is a potential therapy option for motor control deficits in children with CP. The application of tDCS involves positioning 2 rubber electrodes sheathed in saline-soaked pads onto the scalp, held in place by a rubber strap. Low-intensity, direct-current, of 1 to 2 mA, is delivered to cortical areas from the device.~The standard-of-care gait training included various gait training and balance tasks as well as resistive exercises and passive stretching as necessary. Task-specific gait exercises included: walking in a closed indoor environment, walking in an open indoor environment, walking on various floor surfaces, and climbing stairs up and down without assistance. The children also performed dynamic balance exercises by walking on a balance board."

"Virtual reality rehabilitation is an emerging therapy for motor rehabilitation of children with CP. The therapy is provided through a computer-simulated environment where they interact with real-world-like objects and events through sight, sound, and touch. The Wii Remote was used as the interactive interface, and standard computer/television screens were used as the display hardware. Therefore, VR therapy was of the non-immersive type.~The standard-of-care gait training included various gait training and balance tasks as well as resistive exercises and passive stretching as necessary.
