Why Majority of Mouse Designs Fail Part 2 - Trigger Finger & Carpal Tunnel
Are your fingers locking up, are your fingers locking up straight ? Trigger Finger and Trigger Thumb are trigger finger symptoms. Is Trigger finger treatment without surgery an option?
When clicking with the tip region of your index and middle fingers on the traditional mouse, what is actually happening beyond the skin and muscle activation, are the phalanges bones interlocking to form a fixed position during each execution.
Where one click cannot immediately destroy cartilage or causing severe damage to synovial membranes between each section of finger bones. The fingertip clicking motions, over long periods of time, will create impact that will inevitably cause the synovial membranes to wear out.
This degenerative process continues on.
Carpal Tunnel Syndrome
Carpal Tunnel, or carpal tunnel syndrome are often results from fingertip clicking, not a self-inflicting injuries. What? Yes, let me explain.
In the previous article we've discussed on the topic of inaccuracy, and how that has shaped the palm support design we see in majority of mouses, today.
I am now, going to tell you in details why this "quick inaccuracy fix" has caused more unintended harm to the health of your hand than you've ever imagined.
You see, the muscles and tendons move underneath your skin, should be free from weight induced suppression and pressure from over bent angles during exertion, in order to avoid tearing, friction, and damages.
The palm support, which is designed as a quick fix to combat the occasional "jerk" movements caused by fingertip clicking (explained in previous article), in advertised words such as "fits into your palm perfectly", therefore, couldn't help but create massive amount of suppression & pressure, hence tearing, friction, and damages.
Where the hypothenar muscle group is trained to react in hope to control mouse stability, each click, however, generates more need for thumb and pinky to squeeze tight, while the index and middle fingers click harder, ripping tendons apart.
What you end up feeling is now the carpal tunnel pain.
Each fingertip is connected and controlled by the lumbricals for extending, lumbricals are also partially responsible for knuckle control. Lumbricals are affected by muscle suppression from the underside, thanks to palm support.
I will continue writing on this blog another day.
