A method of typing to reduce repetitive strain injuries comprises coordinating the movement of all moving parts from the shoulders to the fingers to avoid dissonant movement of any one part, starting with the hand and forearm in a natural profile. Each separately moving part is limited to movement to within its mid-range of motion. For speed, a finger is lifted and the hand is rotated to amplify the elevation. Conversely, lowering of the finger to strike a key involves rotating the hand in a reverse direction. The fingers are simply dropped, aiming at the top of the key to eliminate wasteful downward force and reduce finger-to-keyboard impact. Major movement of the fingers about the keyboard occurs simultaneously with upper and lower arm motion to eliminate stressful finger motions. A mouse manipulation method also employ the hand in a natural profile. An instruction methods for both the typing and mouse manipulation techniques teaches the student staring from the natural profile and moving in the mid-range of joint articulation. |

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS," one will understand how the features of this invention provide its benefits, which include avoidance or reduction of repetitive stress injury without sacrificing speed.
TYPING METHOD The method of this invention allows a typist to actuate individual keys of an alpha-numeric keyboard in a manner to avoid or minimize repetitive stress injury.
The alpha-numeric keyboard includes a plurality of rows of keys at different heights, including a home row of keys, typically the center row of five rows of keys.
The keys move upon manual actuation by the typist between a normally raised position off a keybed to an actuated position between the keybed and the normally raised position.
The first step of the method is that the typist initially assumes an at rest position by sitting upright before the keyboard, positioning the typist's forearms in a balanced position with the forearms resting down so that the bottom of the elbows are near the sides of the typist at about the same level as the home row of keys.
The typist's hands and wrists are in a natural profile corresponding to the hands and wrists being as if at rest by the typist's side, but instead positioned in front of the keyboard, with the palms of the hands facing downward and the fingers of the hands resting lightly on the keys in a generally vertically orientation.
In the natural profile the hands are not bent at the wrist, and the middle finger and longitudinal axis of the forearm are in alignment, and the fingers are slightly curved.
Each individual typist will have their own unique natural profile.
A balanced position results when the forearm falls forward only under the influence of gravity, bending at the elbow and not bending at the wrist or collapsing the fingers, maintaining the natural profile of the fingers, hand, wrist, and forearm, with the shoulder and elbow in a stable, stationary condition.
A balanced position produces skeletal support for the hands and arms, reducing the muscular effort needed to maintain the natural profile
