Of all organs in the human body, the brain is clearly the most unique. Composed of billions of neurons, the brain circuits constantly process multiple streams of information, perform motor and sensory functions, produce thoughts, and generate a vivid subjective experience of being conscious. We usually take for granted that we can effortlessly perform such complex tasks as commanding our body to move, walking, maintaining balance, generating speech, perceiving the visual world, and recognizing familiar faces. Unfortunately, this flawless neural processing can go wrong when neurological trauma or disease disrupt brain processing, making a person unable to speak, move, feel, attend, or remember. Currently, there is no cure for many devastating neurological conditions, such as spinal cord injury, stroke and amyotrophic lateral sclerosis.
Designing and implementing an electronic system to control moving orthosis virtual mechanical system to emulate lower limb

According to the World Health Organization Center, every year around the world, between 250,000 and 500,000 people suffer from a spinal cord injury. The term “spinal cord injury” refers to damage to the spinal cord resulting from trauma, or from disease. This injury has different effects on patients, including paraplegia, which may accrue if this damage is in the lower or upper part of the back. This causes some loss of trunk movement and complete or partial loss of leg movement. The aim of this work is restoration legged mobility in paraplegic. So that, in this paper an individual rehabilitation treatment approach has been proposed to regain the capacity to walk independently using an ambulatory robotic exoskeleton. The exoskeleton design is lightweight, bilateral wearable device, in which hip, knee and ankle are powered joints, that their movements are controlled by specific strategies using normal gait pattern investigated from healthy people.
