Paraparesis, is a term amalgamated from paraplegia and paresis. The term therefore combines both of these symptoms, with paraplegia denoting paralysis (where movement is difficult or impossible) of the lower limbs, and paresis being a mild paralysis. Paraparesis is thus a slight difficulty in movement of the lower limbs. There are a wide variety of underlying causes, but the most common is progressive multiple sclerosis once it has affected specific cells enabling motor control, known as motorneurons, found in the spinal cord.
