tärinäväsymyksen

Tärinäväsymys, also known as Hand-Arm Vibration Syndrome (HAVS), is a neurological and vascular disorder caused by prolonged exposure to vibration, typically from power tools. It affects the blood vessels, nerves, and joints in the hands and arms. The condition can lead to a range of symptoms, including numbness, tingling, pain, and a loss of sensation in the fingers. In more severe cases, it can cause whitening of the fingers, especially in cold weather, a phenomenon known as vibration-induced white finger.

The primary cause of tärinäväsymys is repeated exposure to hand-transmitted vibration. This is commonly experienced by workers in industries such as construction, forestry, agriculture, and manufacturing who use tools like jackhammers, chainsaws, grinders, and vibrating sanders. The vibration damages the small blood vessels and nerves in the extremities over time. Factors like the intensity and duration of vibration exposure, as well as individual susceptibility, play a role in the development of the condition.

Diagnosis of tärinäväsymys is usually based on a person's work history, symptoms, and a physical examination. Medical professionals may also conduct tests to assess nerve function and blood flow. Prevention is key and involves reducing vibration exposure through the use of anti-vibration tools and equipment, regular maintenance of tools, providing appropriate personal protective equipment like anti-vibration gloves, and implementing work practices that limit exposure time. Treatment focuses on managing symptoms and preventing further damage, which often involves avoiding the vibrating tools and protecting the hands from cold and dampness.
