Tetraplegia, also known as quadriplegia, is a form of paralysis that affects all four limbs of the body due to damage to the spinal cord. The condition arises from injury or disease impacting the cervical spine, which controls motor and sensory functions below the neck. Unlike paraplegia, which affects only the lower limbs, tetraplegia involves complete or partial loss of function in both arms, legs, trunk, and often parts of the torso.

The severity of tetraplegia varies depending on the level and extent of spinal cord injury. Higher injuries, closer to the brainstem, typically result in more extensive paralysis, including loss of respiratory function and control over vital organs. Lower cervical injuries may spare some arm movement while still affecting leg function. Sensory deficits, such as loss of touch, temperature regulation, and pain perception, are also common.

Common causes of tetraplegia include traumatic injuries from accidents, falls, or violence, as well as non-traumatic conditions like spinal cord tumors, multiple sclerosis, or infections such as poliomyelitis. Diagnosis involves imaging studies like MRI or CT scans, along with neurological assessments to determine the extent of damage.

Treatment focuses on managing symptoms, preventing complications, and improving quality of life. Rehabilitation often includes physical therapy, occupational therapy, and assistive devices such as wheelchairs, braces, or adaptive equipment. Surgical interventions may be used to stabilize the spine or decompress the cord. Medications, pain management, and preventive measures for secondary conditions like pressure ulcers or respiratory infections are also critical.

Long-term outcomes depend on the severity of injury, access to care, and individual resilience. Advances in medical research, including stem cell therapy and spinal cord repair techniques, offer potential future treatments for tetraplegia. Support from caregivers, support groups, and community resources plays a vital role in helping individuals with tetraplegia adapt to their condition and maintain independence.
