Cold pressor test in tetraplegia and paraplegia suggests an independent role of the thoracic spinal cord in the hemodynamic responses to cold. Many spinal cord injury survivors are confused by the distinction between quadriplegia, tetraplegia, paraplegia. Find out the difference. 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  Causes‎: ‎Damage to ‎spinal cord‎ or brain by illn.

What is the most appropriate designation for the motor deficit in patients with lower cervical spinal cord injury?

A review of the origin of the terms and nomenclature used currently to describe the neurological status of patients with SCI in the literature was performed. The terms "tetraplegia", "quadriplegia", "quadriparesis", "tetraparesis", "incomplete quadriplegia" or "incomplete tetraplegia" have been used very often to describe patients with complete lower cervical SCI despite the tetraplegia e paraplegia that the clinical scenario is all the same for most of these patients.

Most of these patients have total loss of the motor voluntary movements of their lower trunk and tetraplegia e paraplegia limbs, and partial impairment of movement of their superior limbs, preserving many motor functions of the proximal muscles of their arms superior limbs.

An individual with a C7 injury may lose function from the chest down but still retain use of the arms and much of the hands. A complete severing of the spinal cord will result in complete loss of function from that vertebra down.

A partial severing or even bruising of the spinal cord tetraplegia e paraplegia in varying degrees of mixed function and paralysis.


A common misconception with tetraplegia is that the victim cannot move legs, arms or any of the major function; this is often not the case. Some individuals with tetraplegia can tetraplegia e paraplegia and use their hands, tetraplegia e paraplegia though they did not have a spinal cord injury, while others may use wheelchairs and they can still have function of their arms and mild tetraplegia e paraplegia movement; again, that varies on the spinal cord damage.

Furthermore, the deficit in the limbs may not be the same on both sides of the body; either left or right side may be more affected, depending on the location of the lesion on the spinal cord. September Learn how and when to remove this template message Tetraplegia is caused by damage to the brain or the spinal cord at a high-level C1—C7—in particular, spinal cord injuries secondary to an injury to the cervical spine.

The injury, which is known as a lesioncauses victims to lose partial or total function of all four limbs, meaning the arms and the legs.

Acute spinal cord injury: tetraplegia and paraplegia in small animals.

Tetraplegia is defined in many ways; C1—C4 usually affects arm movement more so than a C5—C7 injury; however, all tetraplegics have or have had some kind of finger dysfunction.

So, it is not uncommon to have a tetraplegic with fully functional arms but no nervous control of their fingers tetraplegia e paraplegia thumbs.


Conversely, it is possible to injure the spinal cord without breaking the spine, for example when a ruptured disc or bone spur on the vertebra protrudes into the spinal column. The ASIA scale grades patients based on their functional impairment as a result tetraplegia e paraplegia the injury, grading a patient from A to D.

This has considerable consequences for surgical planning and therapy. B Incomplete Sensory function preserved but not motor function is preserved below the neurological level and includes the sacral tetraplegia e paraplegia S4—S5.

Tetraplegia - Wikipedia

C Tetraplegia e paraplegia Motor function is preserved below the neurological level; more than half of key muscles below the neurological level have a muscle grade less than 3.

D Incomplete Motor function is preserved below the neurological level; at least half of key muscles below the neurological level have a muscle grade of 3 or more.


Complete spinal-cord lesions[ edit ] Pathophysiologically, the spinal cord of the tetraplegic patient can be divided into three segments which can be useful for classifying the injury. First, there tetraplegia e paraplegia an injured functional medullary segment.


This segment has tetraplegia e paraplegia, functional muscles; the action of these muscles is voluntary, not permanent and hand strength can be evaluated by the Medical Research Council MRC Scale. This scale is used when upper limb surgery is planned, as referred to in the 'International Tetraplegia e paraplegia for hand surgery in tetraplegic patients'.

The lower motor neuron LMN of these muscles is damaged.

These muscles are hypotonic, atrophic and have no spontaneous contraction. The existence of joint contractures should be monitored.

These muscles show some increase in tone when elongated and sometimes spasticity, the trophicity is good. Tetraplegia e paraplegia discussion may be found on the talk page. Tetraplegia e paraplegia help improve this article by introducing citations to additional sources.

September Learn how and when to remove this template message Incomplete spinal cord injuries result in varied post injury presentations. There are three main syndromes described, depending on the exact site and extent of the lesion.
