Paraplegia, or paraparesis, is an impairment in motor or sensory function of the lower extremities. The word comes from Ionic Greek ( παραπληγίη ) "half-stricken". [ citation needed ] It is usually caused by spinal cord injury or a congenital condition that affects the neural (brain) elements of the spinal canal .
A person's level of injury is defined as the lowest level of full sensation and function. [11] Paraplegia occurs when the legs are affected by the spinal cord damage (in thoracic, lumbar, or sacral injuries), and tetraplegia occurs when all four limbs are affected (cervical damage). [12] SCI is also classified by the degree of impairment.
Each class was worth so many points. A was worth 1, B and C were worth 2. D and S were worth 3 points. A team could have a maximum of 12 points on the floor. This system was the one in place for the 1968 Summer Paralympics. Class A was for T1-T9 complete. Class B was for T1-T9 incomplete. Class C was for T10-L2 complete. Class D was for T10-L2 ...
Tetraplegia, also known as quadriplegia, is paralysis caused by illness or injury that results in the partial or total loss of use of all four limbs and torso; paraplegia is similar but does not affect the arms. The loss is usually sensory and motor, which means that both sensation and control are lost.
The class includes people with spinal cord injuries who compete using a wheelchair in track events. They have paraplegia, but have normal hand and arm function, normal or limited trunk function, and no leg function. This class includes CP-ISRA classes CP3 and CP4, and some athletes in ISOD classes A1, A2 and A3.
The spinal cord executes rhythmical and sequential activation of muscles in locomotion. The central pattern generator (CPG) provides the basic locomotor rhythm and synergies by integrating commands from various sources that serve to initiate or modulate its output to meet the requirements of the environment.
Diplegia, when used singularly, refers to paralysis affecting symmetrical parts of the body.This is different from hemiplegia which refers to spasticity restricted to one side of the body, paraplegia which refers to paralysis restricted to the legs and hip, and quadriplegia which requires the involvement of all four limbs but not necessarily symmetrical.
