Do Wrist Rests Prevent Carpal Tunnel Syndrome?

Wrist pads and gel pads are not proven to prevent Carpal Tunnel Syndrome (CTS). In fact, they may actually make matters worse.  The Carpal Tunnel is just big enough for the nerves and tendons that pass through it.  Putting added pressure on the wrist may compress the tunnel and increase chances of the median nerve getting pinched.  If you use or are investigating a wrist rest, ensure that your palm touches the wrist rest lightly only while you are NOT typing. Resting your wrists on the wrist rest while you are typing is actually detrimental as it will place pressure on the wrist and cut off blood circulation to the hand, with negative effects (even if the wrist rest is soft.)  A best practice is to not lower your wrist at all when typing, but rather adjust your desk/mouse so your forearms are almost parallel to the floor.
