Disease profile
A grounded synthesis of the condition — overview, causes, mechanism, risk factors and current standard of care.
Quadriplegia is a severe or complete loss of motor function in all four limbs. It can arise from diseases affecting the brain, spinal cord, peripheral nervous system, neuromuscular system, or, more rarely, muscle. The locked-in syndrome is a related presentation in which quadriplegia occurs with cranial muscle paralysis while consciousness is preserved.
Quadriplegia may result from brain diseases, spinal cord diseases, peripheral nervous system diseases, neuromuscular diseases, or rarely muscular diseases. In locked-in syndrome, it is usually caused by a lesion in the upper brain stem that injures the descending corticospinal and corticobulbar tracts.
The core biological feature is interruption of motor pathways controlling voluntary movement in all four limbs. In locked-in syndrome, damage to the upper brain stem disrupts the descending corticospinal and corticobulbar tracts, producing quadriplegia and cranial muscle paralysis while sparing consciousness. The grounding also links the condition to impaired movement and psychomotor performance.
Underlying diseases of the brain, spinal cord, peripheral nervous system, neuromuscular system, or muscle increase the likelihood of quadriplegia. A lesion in the upper brain stem is a specific risk factor for the locked-in syndrome presentation.

Authoritative identity, definition & identifiers.
Severe or complete loss of motor function in all four limbs which may result from BRAIN DISEASES; SPINAL CORD DISEASES; PERIPHERAL NERVOUS SYSTEM DISEASES; NEUROMUSCULAR DISEASES; or rarely MUSCULAR DISEASES. The locked-in syndrome is characterized by quadriplegia in combination with cranial muscle paralysis. Consciousness is spared and the only retained voluntary motor activity may be limited eye movements. This condition is usually caused by a lesion in the upper BRAIN STEM which injures the descending cortico-spinal and cortico-bulbar tracts.
