Paralysis occurs when communication between the brain and muscles is disrupted due to injury or disease. It can affect mobility, sensation, and independence, significantly impacting daily life. Common types of paralysis include monoplegia (one limb), hemiplegia (one side of the body), paraplegia (lower body), and quadriplegia (all four limbs). While paralysis can be life-altering, advancements in medical science, such as stem cell therapy, offer hope for recovery and rehabilitation.
