What is the Difference Between Paraplegia and Tetraplegia?

🆚 Go to Comparative Table 🆚

The main difference between paraplegia and tetraplegia (also known as quadriplegia) lies in the regions of the body affected by paralysis.

  • Paraplegia is a form of paralysis that affects the legs and sometimes the lower body, typically due to injuries or diseases affecting the spinal cord. It usually occurs when there is damage to the thoracic, lumbar, or sacral areas of the spinal cord. People with paraplegia can move their arms and hands, but may have difficulty with leg movement, bowel, bladder, and sexual function.
  • Tetraplegia (also known as quadriplegia) is a form of paralysis that affects both arms and legs, as well as the chest muscles and abdominal muscles. It usually occurs due to damage in the cervical area of the spinal cord. In some cases, tetraplegia can result in complete loss of movement and sensation in all four limbs, as well as difficulty with breathing, coughing, or clearing the chest.

In summary, paraplegia affects the legs and lower body, while tetraplegia affects both arms and legs, as well as the chest and abdominal muscles. Tetraplegia is generally considered a more severe condition than paraplegia, as it results in a greater loss of movement and function.

Comparative Table: Paraplegia vs Tetraplegia

Here is a table comparing the differences between paraplegia and tetraplegia:

Feature Paraplegia Tetraplegia
Affected Areas Trunk, legs, and pelvic region Arms, hands, trunk, legs, and pelvic region
Spinal Cord Level Thoracic (T1-T12), lumbar (L1-L5), or sacral (S1-S5) area Cervical area
Paralysis Severity Less severe than tetraplegia More severe than paraplegia
Limb Control Retains use of arms Unable to control arms or legs
Respiratory Issues Depends on the severity of the injury Injuries above level C4 often result in respiratory deficiency
Diagnostic Procedures X-rays, CT scans, and MRI X-rays, CT scans, and MRI

Paraplegia is a form of paralysis that affects the trunk, legs, and pelvic region, while tetraplegia (also known as quadriplegia) is a more severe condition that affects the arms, hands, trunk, legs, and pelvic region. The level of the spinal cord injury determines whether the paralysis is classified as paraplegia or tetraplegia, with tetraplegia generally resulting from injuries to the cervical area.
