As a condition of HAVS advances, how may a worker's hand function be impacted?

The condition referred to as Hand-Arm Vibration Syndrome (HAVS) can lead to significant impairments in a worker's hand function. This syndrome is often a result of prolonged exposure to hand-arm vibrations, commonly associated with the use of vibrating tools. Over time, this condition can cause vascular, neurological, and musculoskeletal issues, which manifest as symptoms including numbness, tingling, and pain in the hands and fingers.

Difficulty using hands is a direct consequence of HAVS because the syndrome impacts the blood flow and nerve function in the hands. Workers may experience a reduced ability to grip objects, decreased tactile sensitivity, and overall hand coordination. These challenges make tasks requiring fine motor skills particularly problematic, hindering their ability to perform effectively and safely.

In contrast, options suggesting uninhibited movement, increased strength, or enhanced dexterity do not accurately reflect the effects of HAVS. Instead, HAVS leads to a deterioration in hand functionality, causing difficulties rather than improvements in how workers can use their hands.
