What is dangerous for the hands of long work with a computer and 3 ways to prevent diseases

With the advent of the computer, people's lives have become much easier. But at the same time, new health problems arose. Almost every office worker has encountered hand diseases that have negative consequences.

What is dangerous for the hands of long work with a computer and 3 ways to prevent diseases

Diseases of the hands that occur with constant work at the computer

Active computer users often complain of hand diseases, and the most common of them is tendonitis. This is an inflammation of the tendons, which are subject to constant stress. People of other professions are also exposed to this disease – artists, pianists, tennis players and others who are forced to regularly perform the same mechanical movements with their hands.

Human tendons are incredibly strong and can withstand up to half a ton of weight. But with trauma and uneven healing of damaged fibers, ligament rupture can occur. The inflammation begins at the attachment points of the tendons, with pain in the shoulder, elbow and wrist.

Passive movements usually do not cause painful sensations, so the patient continues traumatic movements. With the progression of the disease, aching pains do not subside even at rest, the inflamed tendons emit a crisp sound when moving.

Carpal tunnel syndrome may occur if you work at the computer frequently. This causes pain in the wrist, hands swell, and tingling appears in the fingers. These syndromes are caused by swollen tendons in the hand that pinch the median nerve that runs through the wrist. Pain occurs when the hands are uncomfortable on the keyboard.

Prevention measures

Doctors recommend limiting the movement of the diseased joint at the first manifestations of the disease, using anti-inflammatory drugs, ointments, plasters, B vitamins, and physiotherapy. It is also worth changing your working mouse.

But it is best to prevent the development of the disease and take preventive measures in advance.

Left-handed mouse operation

Controlling a computer mouse with your left hand will benefit your spine, joints and muscles. Scientist Alvin Delail of the Canadian Institute for Occupational Diseases and Safety in Montreal conducted an experiment. 27 right-handers working at a computer moved their mice to the left side and worked like that for a whole month.

They noticed that the shoulder, arm and wrist were moving less. The movements have a smaller amplitude than usual, since the keyboard is asymmetrical, and it is easier for a right-handed user to earn occupational illnesses. The right hand is forced to deviate more from the middle position, reach for the mouse and make more movements.

After a month, Delail's patients got used to working with their left hand. Many even refused to return the mouse back.

Vertical mouse

Such a device will allow you to get rid of the incorrect position of the brush lying on the mouse. In this case, the hand rotates almost 90 degrees relative to the elbow. The muscles that rotate inward (pronators), the arms and hands are tense, and the arch supports (the muscles that rotate 'outward') are stretched.

This leads to swelling and uncomfortable pressure on the nerves and blood vessels. If you use a vertical mouse, the hand will be in its normal position without stress on the muscles.

At first, using such a mouse will seem unusual and inconvenient. But after a few days, the hand adapts. You will have to move it not with a brush, but with your whole hand because of the unusual coverage.

Trackball

The word trackball comes from the English track and ball and translates as a ball laying a route.

This device looks like an inverted ball mouse. The rotation of the ball is fixed by the longitudinal and transverse rollers, which transmit data to the controller. It supplies them to the central processing unit of the computer.

The trackball is rotated by fingers or palm. It depends on its size. To work with such a device, the body does not need to be moved. Although, when installing additional software, the sensor of the manipulator also detects movement on the table.

Working with such a manipulator uses the fingers, and the hand will be less tired. There are few such devices on the market today. Although the convenience of its use suggests the prospect of further development of such a model.

Thanks to these preventive measures, your hands will always remain healthy when working at the computer.
