In which orthotic situation would a thumb post generally be used?

A thumb post is specifically designed to maintain the function of the thumb, especially when stability and control of the thumb are needed due to injury, neurological conditions, or other functional impairments. By providing support while allowing for some mobility, it helps in preserving the natural grasp and pinching ability that is essential for fine motor tasks.

In some scenarios, limiting wrist motion or immobilizing other fingers might be necessary, but those purposes are typically addressed by other types of orthotic designs that focus on the wrist or other fingers, rather than specifically on enhancing or preserving thumb function. Thus, the use of a thumb post is crucial in ensuring that the thumb can perform its necessary roles while still being supported.
