Spinal cord injury (SCI) at C1-C8 generally results in which condition?

1. Paraplegia

2. Quadriplegia

3. Tetraplegia

4. Neuropathy

The correct answer is: Quadriplegia

The condition resulting from spinal cord injury (SCI) at the C1-C8 level is characterized as quadriplegia. This term refers to paralysis that affects all four limbs—both arms and legs—due to the injury's impact on the cervical segments of the spinal cord. Because these segments are responsible for motor control and sensory function of the arms, legs, and trunk, any damage within this region can severely impair movement and sensation. Quadriplegia can vary in severity, with some individuals retaining limited function in certain muscle groups while others may experience complete paralysis. The specific site of injury within C1 to C8 also plays a role in the extent of functional loss; for example, injuries at C1-C3 can lead to loss of head and neck control, while those at lower levels like C7 may still allow for some arm movement. The other conditions listed, such as paraplegia, refer to paralysis affecting only the lower limbs and are typically associated with injuries to the thoracic or lumbar regions of the spinal cord. Tetraplegia is often used interchangeably with quadriplegia and also describes paralysis affecting all four limbs. Neuropathy, on the other hand, refers to nerve damage often resulting from various conditions
