Wrist injuries are typically caused by one of two reasons. The primary cause is due to repetitive use of the wrist. This causes strain on the tendons and nerves that support the area, which leads to wrist pain. The other common reason is due to impact, usually during physical activities. Our natural reaction when falling is to put our hand out and land on our wrist, which can cause wrist fractures or other injuries. Cock-up splint can be used as a post traumatic rehabilitation aid to get the injured wrist back in shape. They do this by stabilising the wrist area and preventing the joint from moving unnaturally or out of place.
