Paraplegia is an impairment in motor or sensory function of the lower extremities. The word comes from Ionic Greek παραπληγίη) "half-stricken". It is usually caused by spinal cord injury or a congenital condition that affects the neural (brain) elements of the spinal canal. The area of the spinal canal that is affected in paraplegia is either the thoracic, lumbar, or sacral regions. If four limbs are affected by paralysis, tetraplegia or quadriplegia is the correct term. If only one limb is affected, the correct term is monoplegia. Spastic paraplegia is a form of paraplegia defined by spasticity of the affected muscles, rather than flaccid paralysis.

Methods for closed-loop neural-machine interface systems for the control of wearable exoskeletons and prosthetic devices
Brain-Machine Interface (BMI) systems or movement-assist systems may be utilized to aid users with paraplegia or tetraplegia in ambulation or other movement or in rehabilitation of motor function after brain injury or neurological disease, such as stroke, Parkinson's disease or cerebral palsy. The BMI may translate one or more neural signals into a movement type, a discrete movement or gesture or a series of movements, performed by an actuator. System and methods of decoding a locomotion-impaired and / or an upper-arm impaired subject's intent with the BMI may utilize non-invasive methods to provide the subject the ability to make the desired motion using an actuator or command a virtual avatar.

Paraplegia prevention valve for stent grafts
A stent graft defining a main lumen bounded by a wall of graft material is disclosed. The stent graft has a valve portion between proximal and distal portions. The valve portion is formed by a wall portion having a part-circumferential double layer portion comprising an inner underlap portion and an outer overlap portion, the double layer portion forming a passageway parallel to the main lumen. The passageway has an entrance mouth and an exit mouth. The passageway has an open condition where the underlap and overlap portions are spaced apart to form a vent lumen. The wall portion is broken by a narrow cut. The cut is openable by relative radial movement between its edges. This allows re-perfusion of an aneurism and perfusion of blood from within the lumen out towards blood vessels such as intercostals and can assist in minimising the chance of paraplegia.
