The Carpal Solution is not an immobilizing brace technique. It operates with a completely different mechanism.
Immobilizing braces and night splints are constructed of rigid plastic and are restrictive and uncomfortable to wear. They cause muscle atrophy and due to the rigid nature of cock-up night splints, they often interrupt sleep, interfere with free movement and can annoy partners sharing the same bed and are only marginally effective.
Rigid orthotics hold the hand in a neutral position, and do prevent pain from movement, but they also irritate and compress already injured inflamed tissue and result in muscle atrophy.
They are also inconvenient and uncomfortable.
