Quadriplegia is a medical condition characterized by the loss of movement and sensation in all four limbs, typically resulting from a spinal cord injury or disease. This condition affects both the arms and legs, leading to varying degrees of paralysis and loss of function. Individuals with quadriplegia may also experience challenges with bodily functions, such as breathing and bladder control. The severity of quadriplegia can differ based on the location and extent of the spinal cord injury. Rehabilitation and therapy are essential for improving quality of life and maximizing independence. Supportive devices and assistive technologies can help individuals with quadriplegia perform daily activities.
