The biodynamics of human hand-arm system is one of the most important foundations for the
measurement, evaluation, and risk assessment of hand-transmitted vibration (HTV) …

Muscle fatigue can cause people to change their movement patterns and these changes
could contribute to acute or overuse injuries. However, these effects depend on which …

Assembly workers using handheld powered tightening tools are repetitively subjected to
reaction loads resulting from the tool handle. Despite the vast amount of research, tool …

This paper presents the modeling of the user's dynamics synchronized with a wrist and
forearm exoskeleton of 3 degrees of freedom (DoF). The biomechanical model includes …

Powered hand tools produce reaction forces that may be associated with upper extremity
musculoskeletal disorders. The handle displacement, grip force and upper limb muscle …

Powered hand tools have the potential to produce reaction forces that may be associated
with upper extremity musculoskeletal disorders. In this study, subjective ratings of discomfort …

The product development of power tools struggle with the complex interaction of the power
tool, the user and the application. Current investigations of the functional reliability of impact …

Hand–arm vibration syndrome (HAVS) is very common among the workers operating power
tools and doing similar nature of work for long hours. Grass trimming is one of the operations …

Background. Submaximal eccentric exertions occur occupationally when rapidly rising tool-
generated forces exceed the operator's capacity to react against them. The purpose of this …
