Place the mouse on the same level as and immediately next to the keyboard tray.
Keep the mouse in the arc line of the keyboard so that you can reach it when rotating your arm from the elbow.
Do NOT use a wrist rest while using the mouse. Your forearm needs to be free to move so you do not strain the wrist.
Make sure the keyboard is placed directly in front of the user.
The mouse should be positioned at the operator's side with his or her arm close to the body. A straight line should be maintained between the hand and the forearm. The upper arm should not be elevated or extended while using the mouse. The employee should not have to reach to use the mouse.
Consider using a mouse platform that rotates above the keyboard while maintaining about the same plane. This design allows the mouse to be used above the 10-key pad, which gives the user a better wrist angle and reduces reach.
Position the keyboard slightly below the elbow and at a negative angle to allow the wrists to remain straight when you sit in a slightly reclined posture
Do NOT use a wrist rest while actively typing. It’s meant to rest on not to lean on when working. Hold your hands and arms off of any supports while typing.
Do NOT use the keyboard supports to raise the back up. Do NOT tilt the keyboard tray so that the back of the keyboard is higher than the front. Though design and a lot of prevailing information say you should tilt the keyboard to a positive angle like this, it is wrong. A negative angle that allows the wrists to stay in their natural wrist position is better. A positive angle is an repetitive stress injury waiting to happen.
