Who used strong oscillating tools such as drills, jackhammers, different types of saw tools, and other power tools often cause itchiness and burn in the arms. That is actually because of the vibration that is created by the machine. The tools mentioned above produce a higher level of vibration (such as rapid back and forth motions). The vibrations get transmitted in the hands and the arms of the user while they held the machine.
The symptom is known as Hand-Arm Vibration Syndrome (HAVS) in medical terms. We have discussed this symptom briefly in below. Keep reading this article to know much about the sign as well as its prevention.
Hand-Arm Vibration Syndrome (HAVS)
As we mentioned earlier, the Hand-Arm Vibration Syndrome (HAVS) is the medical term of the pains that are caused by different types of vibrating tools. The HAVS injuries are divided into three subcategories.
- Neurological Injuries
- Vascular Injuries
- Musculoskeletal injuries
It is the early stage of HAVs Injuries. The symptoms usually include numbness or tingling in the fingers and the hand. Then it may turn into limited dexterity and impaired sensibility. The neurological injuries are irreversible when fully developed.
It can cause a high level of work impairment and disability. In this stage, the patient may find it hard to hold any tools, and he or she may find it hard to insert a key in the lock or to pour the water in a glass.
The vascular injuries usually affect the small blood vessels (capillaries) in hand and force them to compress. If the problem occurs to you, you may also feel blanching or white fingers in case of exposure to cold. In the medical term, the problem is known as Vibration-Induced White Fingers (VWF) or Secondary Raynaud's Disease".
Blanching temporary restrict blood circulation in the fingers or the hands. And the area will become white, and the person may experience numbness in the area. After the temporary restriction of blood circulation, the person may feel severe discomfort or tingling and soreness in the affected section of the body.
Musculoskeletal injuries can cause tendonitis, arthritis, or sometimes even changes in the muscle fibers. In the long run, it can create impaired grip force and reduced mobility in the affected area.
There is no obvious explanation on how the vibration affects the grip strength. However, according to some studies, it may happen because of damaged nerves and muscle structure. Typically, these types of injuries are hard to diagnose as the routine clinical tests can't detect it.
How to relieve Hand-Arm Vibration Syndrome?
Taking the below steps may reduce the chance of HAVs injuries:
- Go for a machine which produces less vibration as well as complete the job faster. Moreover, choose a machine with a higher power-to-weight.
- Choose a tool which comes with optimal ergonomic design. It should come with a comfortable grip, optimal angle of the main handle, and a short distance between the front and the support handle in case it functions in a horizontal orientation.
- You can also increase the power of the machine to reduce the using time.
- The user of the instrument should be adequately trained to maintain the right position and posture while working with the machine.
- Sometimes the vibration is caused by defective tools. In such cases, consider changing the tool.
Hand-Arm Vibration Syndrome should be carefully treated. Else it may cause many serious problems. Hopefully, this piece of information will help you to know better about Hand-Arm Vibration Syndromes.
