Which type of orthosis is designed primarily to improve hand function?

Wrist-hand orthoses (WHO) are specifically designed to support and enhance the function of the wrist and hand, making them particularly effective in improving hand function. This type of orthosis aids in stabilizing the wrist in a position that promotes optimal hand mechanics, which is crucial for performing daily activities that require dexterity and coordination. It can also assist in preventing contractures and providing support after injuries or surgeries in this region.

The focus of the WHO is directly on the hand and wrist, allowing individuals to engage in tasks requiring fine motor skills, such as writing, grasping objects, or typing. This makes it a vital tool in rehabilitation settings for individuals with conditions affecting hand function, such as strokes, arthritis, or neurological impairments.

Other types of orthoses, like the ankle-foot orthosis, knee-ankle-foot orthosis, and sacroiliac orthosis, serve different purposes, focusing on stability and support for lower extremities and the pelvic region rather than enhancing hand functionality.
