What are some finger/hand exercises that help prevent carpal tunnel?

Prevention: I am not aware of any exercise that does this, but be aware that cts mostly is a cumulative trauma disorder, associated with repetitive flexion/extension of wrist due to keyboard work, assembly line work, etc. Might consider wrist pad for computer, might try wrist splints, at night, might supplement one b-100 complex daily, and avoid the above risks.

None effective: There are no exercises that have been scientifically shown to prevent carpal tunnel syndrome.
