A spinal cord injury (SCI) occurs when there is damage to the spinal cord, which can disrupt communication between the brain and the body. This injury can result from trauma, such as a car accident or a fall, or from diseases like multiple sclerosis. The severity of the injury can vary, leading to different levels of impairment. Symptoms of a spinal cord injury may include loss of movement, sensation, or reflexes below the injury site. The effects can be temporary or permanent, depending on the extent of the damage. Rehabilitation and therapy are often essential for recovery and adapting to new challenges.
