From the looks of the brace it looks like your wrist can still move into flexion or extension depending on what your doing, but I wouldn't really know because I've never seen a brace like that. Ideally you want your wrist to be closer to a neutral position so that the tendons and nerve can have adequate space to move through the carpal tunnel which can be difficult when you're typing all day.

My wife works on a computer all day and I got her a brace like the one below because i thought it would be able to hold her wrist in a more neutral position while she was typing because it crossed the wrist joint.
