Wrist support refers to braces, splints, or wraps that stabilize, protect, and provide compression to the wrist joint, helping with pain relief, injury recovery (sprains, tendonitis, carpal tunnel), and preventing re-injury during activities like typing, lifting, or sports. They work by limiting motion, reducing swelling, and promoting proper alignment, with types ranging from simple compression sleeves to rigid splints for immobilization, often made from neoprene or elastic materials.
