Generally, when a muscle or soft tissue is inflamed, swollen or stiff due to repetitive stress injury, fatigue, over exertion or other injury the space between the skin and muscle is compressed, constricting the flow of lymphatic fluid and inhibiting circulatory action.
The body possesses remarkable healing power when it is able to function naturally.
Normal circulation of the blood in the hand transports nutrient rich blood to cells and carries away toxins and excess fluids from damaged tissue.
However, compressed tissue due to injury restricts blood flow and limits lymphatic fluid exchange in and around the injury blocking the natural healing process.
Rigid wrist splints and hand braces, like the Cock-up Splint, compress this tissue further when straps are cinched up tight. Further compressing this injured tissue usually complicates the natural healing process and often leads to surgery.
This compression also applies pressure to the pain receptors beneath the skin, which in turn communicates, “discomfort signals” to the brain; the person experiences PAIN.
This type of pain is known as myalgia, or muscular pain.
In the case of Carpal Tunnel Syndrome the pressure from swelling is compounded dramatically because the pressure from swollen injured tissue affects an extremely vulnerable area which is where the Median Nerve, tendons and blood vessels pass through a restricted channel made up of bones and tough ligaments, we know as the Carpal Tunnel. The Carpal Tunnel becomes a pinch-point. When a nerve is pinched against strong tendons, any movement can result in excruciating pain.
