Biomechanical research has shown that a palm supporting surface provides a better solution to prevent neck, shoulder, arm and hand complaints. For example in view of the reduced or possible absence of grip forces a computer mouse design according to this concept is to be preferred.
An additional point of attention is the angle of the supporting surface. This angle can have a significant (negative) effect on muscle tension for example in the “neutral (900 supination) or handshake position”.
