Pushing and gripping forces may contribute to Hand-Arm Vibration Syndrome but have not been taken into account so far in vibratory dose assessment according to current standards. To obtain better understanding of symptom onset, we developed…

The exertion of force by an operator in order to hold or guide a machine has an impact on the level of vibrations transmitted to the hand. Prolonged exposure to high levels of vibration can lead to the development of hand-arm vibration syndrome…

Acute exposure to hand-arm transmitted vibrations (HAVs) may decrease the Wall Shear Stress (WSS) exerted by the blood flow on the arterial endothelium. In the case of chronic exposure to HAVs, these WSS changes can lead to arterial growth and remodeling…

Understanding the mechanical behaviour of hand muscles might result in better grasping the onset of pathologies associated with the use of hand-held machines. With the aim of identifying the parameters of constitutive laws of such muscles…

Prolonged exposure to vibrations from handheld tools can result in various disorders. Understanding how vibrations propagate through the hand is a key area of research involved in preventing these disorders. Within this framework, it is essential…

Outline of reasons and objectives
Today, in France, approximately 11% of salaried workers are exposed to vibration transmitted to the upper limb. Prolonged exposure to high levels of vibration can lead to a certain number of pathologies. To try…

Vibration dose assessed by current standards is likely to be poorly suited to protecting workers against vibration white finger (VWF). Therefore, we intended for a two-step approach to better tackle vibration-induced pathophysiological vascular…

The health effects of vibrations transmitted to the hand-arm system are elicited by a chronic exposure along the worker s lifetime. It is challenging to ascertain the precise nature of these phenomena without undertaking epidemiological…

The physiopathological mechanisms induced by exposure of the hand-arm system to vibration are still ill-known, despite the steps taken by the European States to protect workers. That lack of knowledge lies behind the lack of representativeness…

Sustained exposure to high-level hand-transmitted vibrations may result in angioneurotic disorders, which partly originate from vibration-altered hemodynamics in the finger arteries when repeating these disturbances throughout working…
