Assessment factors
These included: the Subjective Perceived Annoyance (VAS)
and the muscular reactions characterized by changes in
power (MVC e Maximal Voluntary Contraction) and endurance
(MPF-Median Power Frequency) of the forearm muscles
(M. Wrist flexor and extensor Carpi Radialis, left and
right) and the upper part of M. Trapezius, (left and right).
These muscles are representative for stress in administrative
work and housekeeping activities by dynamic repetitive
contractions of forearms and postural, static muscle
load in the shoulders.
