Pronation in the forearm and wrist occur in a typing position as the palms of your hand are turned face down and parallel with the flat surface of the desk or floor. The majority of this turning involves the rotation of both forearm bones (the ulna and radius). Sustained pronation increases pressure on the forearm muscles and surrounding tissues and reduces blood circulation which can lead to fatigue and injury. Research demonstrates that a moderate elevation of the thumb side of the hand (laterally sloping the keyboard) dramatically reduces this type of stress.

Unlike traditional flat keyboards that force your forearms and wrists into pronation, the Freestyle2 family offers three accessories that provide variable and reproducible tent settings (VIP3, V3 and Ascent accessories) to greatly reduce pronation.
