تعريف
Paraplegia is the word used to describe the body’s loss of movement and/or feeling as a result of an injury to the nervous system. Paraplegia is complete or partial paralysis of the lower half of the body.
Some patients may resume some function. Many patients with paraplegia may have long term loss of function.
أسباب
Injury to the nervous system is the most common cause of paraplegia. Common injuries and other causes include:
- Broken neck
- Broken back
- سكتة دماغية
- اصابة الحبل الشوكي
- Genetic disorder (hereditary spastic paraplegia)
- Congenital (present at birth)
- العدوى
- أمراض المناعة الذاتية
- Tumor (either within the spinal cord or pushing on the spinal cord)
- Syrinx (a spinal cord disorder)
عوامل الخطر
Paraplegia is often the result of an accident. People who participate in high-risk or high-contact sports or those who drive recklessly may be at greater risk.
الأعراض
Symptoms will depend on how much of the spinal cord is involved. Symptoms include:
- Loss of movement or muscle control in the legs, feet, toes, or trunk
- Loss of feeling in the legs, feet, toes, or trunk
- Tingling in the legs, feet, toes, or trunk
- Loss of bowel and bladder control
- الصعوبات الجنسية
التشخيص
Your doctor will ask about your symptoms and medical history. A physical exam will be done. Neurosurgeons, orthopedists, and neurologists are involved in diagnosis after a paralytic injury has occurred.
Your doctor may need to view your spine. This can be done with:
- الاشعة المقطعية
- تصوير الرنين المغناطيسي
- تصوير النخاع
Your doctor may need to test your body fluids. This can be done with:
- تحاليل الدم
- البزل القطني
An evoked potential nerve test may also be done to evaluate the nerve’s pathways.
العلاج

Emergency Medical Treatment
If you have an injury that causes paraplegia, emergency treatment is needed to prevent further damage to the nervous system. An evaluation will be done to determine the amount of damage. The doctor will decide what therapies are needed to prevent further injury and improve recovery. Steroids may be used to reduce the swelling of the spinal cord if it has been injured. Surgery may be done to help stabilize or relieve pressure on the spine. Surgery may be needed if a tumor is pushing on the spinal cord. Radiation therapy is another treatment option.
Therapy and Rehabilitation
In most patients, physical therapy and rehabilitation may help restore muscle function. Occupational and speech therapy may also be helpful.
الوقاية
Paraplegia is most often caused by injury or accident. The chance of injury resulting in paraplegia may be reduced by paying careful attention to environmental factors. Using safety equipment when playing sports and wearing seatbelts when driving will help reduce the chance that an accident will cause serious injury. You can also reduce these chances by avoiding risk-taking activities, like driving while under the influence or driving when tired.
