Some time ago, a colleague asked me, saying that the joint of her right wrist always feels swollen and painful, and it seems to be getting worse and worse, what should I do?
My first reaction was to get a "mouse hand", right?
The reason for this is that I have also tried carpal tunnel syndrome caused by working with the Apple Magic Mouse for a long time. Fortunately, I switched to a vertical mouse right away, so it didn't continue to deteriorate.
So the question is, why can vertical mice avoid carpal tunnel syndrome, commonly known as "mouse hand"?
What is carpal tunnel syndrome?
Carpal tunnel syndrome is a hand disorder caused by compression of the nerves inside the carpal tunnel. Symptoms include numbness, tingling and weakness in the fingers. One of the reasons is that with prolonged mouse use, repetitive movements can compress the nerves in the carpal tunnel, resulting in numbness, tingling and weakness in the fingers. This is the main reason why carpal tunnel syndrome is also known as the "mouse hand".
I was lucky to find out earlier, but even then, it took a long time to recuperate and recuperate. And many people do not pay enough attention to numbness and pain in the wrist, and finally can only be treated by surgery.
Can a vertical mouse really save the "mouse hand"?
I specially made a comparison chart to make it easier for everyone to understand.
Our current common mice on the market can be roughly divided into three categories:
1, ordinary mouse: the entire upper surface of the mouse is basically at the level of the desktop, when using the wrist needs to be the front arm extension line for the axis of rotation of about 90 ° to use, when the mouse moves left and right, it will be mainly to rotate the wrist, so the pressure acting on the wrist is more obvious, but the advantage is that the left and right hands are compatible;
2. Ergonomic mouse: refers to other mice designed with human body work excluding vertical mice, the surface of the mouse has an angle of about 15° to the desktop, reducing the pressure on the carpal tunnel nerve and blood vessels caused by wrist rotation, but still rotating the wrist when traversing left and right, so it can only alleviate wrist pressure and fatigue to a certain extent;
3. Vertical mouse: the plane where the left and right buttons of the mouse are located and the desktop form an angle of more than 45°, the wrist basically does not need to rotate inward can be easily operated on the mouse, and the left and right traverse is to rotate the forearm elbow instead of the wrist, so the pressure acting on the wrist can be greatly reduced.
Another angle to compare the general mouse with the vertical mouse, it will be more obvious.
We know that the inside of our wrist joint is where a large number of blood vessels and nerves must pass. When we use a normal mouse, the forearm muscles twist and tighten inward, so that the blood vessels and nerves on the inside of the wrist are also compressed. Moreover, long-term muscle tightness can easily produce muscle spasms, and over time it will easily cause wrist muscle fatigue.
When the vertical mouse is used, the wrist does not need to be turned inward, so the forearm and wrist muscle groups will be in a relatively relaxed state, and it is naturally not easy to strain.
In addition, another advantage of the vertical mouse is that its holding posture determines that its main force is not on the fingers, but by the elbow joint to drive the forearm and wrist to translate together, so that not only the movement can be larger, but also because of the "lever principle", the movement will be more labor-saving.
In contrast, ordinary mice, including Apple Magic Mouse, are inevitably suspended in the palm when used, and the power of mouse translation is completed by the wrist and fingers, and the torque is short, which is naturally more laborious.
Here I briefly summarize this part of the knowledge:
1. Vertical mouse refers to the angle between the plane and the desktop composed of the two main keys of the mouse≥ 45°, and <45° is only ergonomic design at best;
2. The main purpose of vertical mouse is to reduce the compression of carpal tunnel and the inner blood vessels and nerves of the wrist joint when the wrist is turned inward;
3. The horizontal movement of the vertical mouse is completed by driving the forearm and wrist to the elbow joint as a whole, rather than relying on the force of fingers and wrists, so it is more labor-saving.
Logitech Lift office mouse as a vertical mouse, is it easy to use?
As a Logitech party, I have hardly left Logitech keyboards and mice since my first computer. Logitech has also introduced several ergonomic mice, including vertical mice. The most well-known of these is probably MX Vertical.
The Lift this time is actually designed for the MX Vertical's large body size, and is redesigned according to the Asian hand size, so as to meet the use of small palms and female users.
In fact, I have also used several vertical mice, including Shanye and Colorful have also used, plus Logitech, which is basically the 3 main brands of common vertical mice at present.
But maybe because the white color itself is small, anyway, visually speaking, Lift should be the smallest vertical mouse I have ever used.
But being small doesn't mean it's bad to hold.
In fact, for a 175cm tall boy like me, Lift can also be held tightly in the hand, and the palm part fits perfectly on the back of the mouse.
The Lift's styling is similar to that of the MX Vertical, but the overall scale has been reduced. Because of this, it also basically retains the good and scientific grip of MX Vertical, especially the design of the left side inward, on the one hand, it can make full use of the thumb to provide stable support for mouse button operation, and reduce the mouse drift problem caused by the key force common to vertical mice; On the other hand, the skirt that extends outward can give the thumb good support and reduce finger tendon fatigue.
The front half of the mouse has a matte texture, which is not easy to leave fingerprints. The second half is a terrace-like skin-like texture, which in addition to playing an anti-slip effect, it also has a certain sweat-wicking effect.
In terms of the number of keys and layout, Lift is not much different from MX Vertical, the two have the same number of keys, but the original MX Vertical DPI switch key on the top decorative panel has been moved between the two primary keys, behind the scroll wheel. Lift provides 2 levels of DPI switching, but the official does not give Lift's specific DPI parameters, and it is only displayed as a percentage of pointer movement speed in the supporting APP.
The two main keys of Lift are all silent design, and the button feel is soft, which is more suitable for girls' slender jade fingers. In contrast, the scroll wheel is equipped with Logitech's own Smart Wheel wheel, and also uses silent processing, with a good sense of passage and moderate damping.
In the thumb position, 2 additional custom buttons are arranged, and the forward and backward functions are in the default state. However, if we choose to turn on Logitech Voice when installing the APP [Logi Options+], we can specify one of them as a shortcut button to wake up.
In addition, Lift does not directly configure the horizontal scroll wheel like MX Master, but provides another solution - when you need to scroll horizontally, you can press either of these two custom buttons first, and with the scroll wheel, it can become a horizontal scroll. This is a super intimate feature for me who often needs to edit video and audio.
Lift supports the memory of 3 Bluetooth devices and switches them with buttons on the bottom of the mouse. Here I also found a small detail - whenever I lift the mouse, the device connection indicator at the bottom automatically lights up. I was thinking, wouldn't that be power-intensive? After closer inspection, I found that Lift detects if the mouse is placed on the desktop, and only briefly lights up when I leave the desktop, so that I can quickly see the currently connected channel.
Compared to MX Vertical, which uses a built-in battery and charges it through the C port, the Lift is not so high-end, and uses a traditional single-cell AA battery to be responsible for power supply. However, Logitech's mice have always been very power-efficient, and it is normal for a battery to last 3 or 5 months.
What is more interesting is that the battery compartment cover of the Lift is not fixed by snaps, but by the 3 magnets on the back of the cover, which are just adsorbed on the 3 fixing screws of the mouse. When it is time to open the battery compartment, simply press the side near the toggle switch and the compartment cover will be cocked for easy removal.
Lift naturally also supports Logitech's own Logi Bolt USB wireless connection, and the dedicated receiver can also be stored directly into the fixed card slot of the battery compartment. In fact, in the case of Bluetooth connection, I rarely use the connection method of USB receiver. So I am very disgusted that Rapoo's mouse always has a USB receiver nowhere to place, and over time, it is always unclear which receiver corresponds to which keyboard or mouse. And Logitech Lift does this, naturally there is no such trouble!
The official weight of the Lift is only 125 grams, and the actual AA battery and USB receiver are 132 grams, which is relatively light. However, the workmanship of the whole mouse is very solid, whether it is the fineness of the mold, the smoothness and evenness of the seam, and the feel of the material, there are not too many faults, showing Logitech's consistent excellent workmanship.
In addition to being a mouse, Lift is also a multi-faceted helper
In the supporting APP [Logi Options+], in addition to setting the resolution of each button and pointer, you can also perform EASY-SWITCH multi-device connection management, and the design of the FLOW cross-computer control and file sharing function that Logitech mouse is almost standard.
In addition to this, Lift also supports the SMART ACTIONS feature. Some friends will ask, what is the difference between this SMART ACTIONS and the general custom buttons and macro buttons?
SIMPLY PUT, SMART ACTIONS CAN SPECIFY THE PURPOSE OF A BUTTON, AND THE CUSTOMIZED CONTENT CAN INCLUDE APPLICATIONS, MOUSE MOVEMENTS AND CLICKS, TEXT QUICK PASTING, SYSTEM SETTINGS THESE FOUR SECTIONS, AND CAN FREELY COMBINE AND ARRANGE MULTIPLE ACTIONS, THUS CONSTITUTING MORE COMPLEX OPERATION INSTRUCTIONS.
FOR EXAMPLE, I CUSTOMIZED SUCH A SMART ACTIONS, WHEN PRESSING THE BACK BUTTON, IT WILL AUTOMATICALLY SWITCH THE BROWSER TO THE FOREGROUND, AND IMMEDIATELY REFRESH THE PAGE, DELAY 2 SECONDS AND WAIT FOR THE PAGE TO LOAD, CLICK THE FIRST CONTENT TO OPEN...
Of course, you can also expand more uses yourself. SMART ACTIONS CAN BE COMPATIBLE WITH MOST MAINSTREAM APPS AND HAS CORRESPONDING FUNCTIONS, SO THE PRACTICALITY IS QUITE HIGH.
summary
In general, the Logitech Lift vertical mouse not only fits the Asian hand shape, but also effectively protects the wrist and avoids the "mouse hand". At the same time, it also has a very rich, human, intelligent multi-function, can help us deal with things more efficiently in work and life, so it is quite worth getting a mouse~!
