Study Finds Vibrations Cause Capillary Walls in the Hand to Thicken

The Raynaud’s phenomenon is associated with many afflictions, including a number of autoimmune diseases like arthritis and lupus. Cold or wet conditions often a trigger the narrowing of blog vessel which is why an excellent pair of self heated gloves for Raynaud’s can provide pain relief. But sometimes Raynaud’s isn’t caused by cold and wet conditions. Many occupational hazards, such as vibrations, have been known to cause Raynaud’s disease symptoms and trigger attacks.


Hand-Arm Vibration Syndrome (HVAS) & Raynaud’s Disease


Individuals who experience tingling and numbness, as well as a change in finger color, are sometimes diagnosed with a secondary form of Raynaud’s Disease called Hand-arm vibration syndrome (HAVS). Repetitive vibration from tools or machinery can result in damage to the fingers, hands, and arms, leading to Raynaud’s disease.

A study published in the Journal of technical Behavior of Biomedical Materials called “A two scale modeling and computations framework for vibration induced Raynaud’s syndrome,” found that vibration-induced Raynaud’s seems to be caused by the thickening of the capillary walls within the hand. Vibrations from long-term use of power tools can permanently damage tissue in the hands and arms resulting in HAVS. This type of tissue damage is irreversible and can only be managed after it’s been done.

In this study, a team of French researchers built a model to explore how the artery wall structure changed when exposed to vibration. However, replicating the elapsed time to cause long-term tissue damage in a model proved to be more challenging than they’d anticipated. In order to accurately study this affliction, the team split the model into two and developed a method for transitioning between them. With two models, they were able to link vibration to capillary growth with the help of so-called biomechanical chaining.

The results of the study showed that vibrations cause capillary walls to become thicker, which in turn causes Raynaud’s symptoms to appear and furthermore HAVS to set it. They noted in the report, “The vibrations emitted by the hand-held power tool are … linked to the capillary growth through the adopted biomechanical growth model at the capillary level. The obtained results show that vibrations induce an increase of the thickness of the capillary’s wall.”

While Hand-arm vibration syndrome isn’t induced by cold and wet conditions, it is recommended that individuals who experience repetitive vibrations keep their hands warm.
