Why mousing leads to Carpal Tunnel Syndrome? (also called Repetitive Strain Injury)? |
(1) Unnatural hand held position (wrist pronation)
Most conventional mice force the hand, wrist, and forearm to be twisted away from the natural and relaxed position. This requires constant strain applied to the hand, wrist, and forearm in order to maintain the position. The unavoidable twisting is a strain on the related muscles, tendons, and nerves.
|
(2) Excessive finger clicking
All conventional mice and most ergonomic mice require constant finger clicking that results in continual strain on the related muscles and tendons. This repetitive strain on the hand and fingers eventually leads to inflammation and swelling of the flexor tendons. Carpal Tunnel Syndrome occurs when swollen flexor tendons compress the median nerve, which runs from the arm to the hand through a space in the wrist called the carpal tunnel found under the transverse carpal ligament. |
(3) Stress from long time gripping
Users have to keep gripping most conventional mice to move and control the cursor, long time stress from gripping leads to strain on hand. |
(4) Pressure and friction between wirst and desk surface
For all conventional mice, user's hand keeps palm down position. The downside of wrist has to bear the weight of hand and contact the desk surface all the time during usage. The pressure on the wrist will press the transverse carpal ligament and reduce the space for medium nerve. |
(5) Strain from finger hovering for preparation to click
For all conventional mice, some fingers of user's hand especially fingers excuting left clicking and right clicking have to prepare to click all the time before next clicking. So these fingers can't get relaxed all the time. |
(6) Insufficient rest during long periods of mouse usage
Most of us don’t take frequent or sufficient breaks when using a computer for an extended period of time. Especially when using a conventional mouse, the hand tends to stay in an unnatural position the entire time, even when not operating the mouse.

Why Rockstick 2 is born to relieve Carpal Tunnel Syndrome? |
(1)Reduces Wrist and forearm Pronation:
The concave depression on the thumb side of the mouse combined with the downward slope towards the mouse towards the fifth finger positions the hand at a 60° angle off the horizontal, which is a more natural position for your wrist and forearm. |
(2)Reduces Pain and Strain on Fingers due to Clicking:
The unique design of the Rockstick mouse allows users to click by utilizing the strength of the entire hand instead of fingers alone.The repetitive strain on fingers eventually leads to inflammation and swelling of the finger flexor tendons. Carpal Tunnel Syndrome occurs when swollen finger flexor tendons compress the median nerve, which runs from the arm to the hand through a space in the wrist called the carpal tunnel found under the transverse carpal ligament. |
(3)Reduces Grip Requirements:
The slanted semi-fist shape of the handle design allows gravitational force on the hand to be employed to provide the majority of the control required to precisely move the mouse; The need to grip the mouse which is one cause of hand fatigue is largely reduced. |
(4)Eliminates pressure and friction between little Finger and Desk Surface:
The Ergo-Grip design with detachable ledge keeps the underside of the little finger and palm off the surface of the desk. Also the downside of wrist doesn't press the desk surface anymore. |
(5)Eliminates Finger Hovering and Lifting:
The unique design of the Rockstick mouse allows users to rest fingers on the handle without preparation to click, all fingers remain relaxed and supported at all times. |
(6)Reduces work load for both hands:
The ambidextrous design of the Rockstick 2 mouse allows users to operate by either the right or left hand. This feature enables users to work balance throughout the day by distributing the repetitive actions of mousing to both hands, thereby providing rest periods for both hands. |
