A study was carried out by Raffi et al. (1996) among workers on an agricultural farm. The workers’ histories were taken and they were given periodical medical check-ups. The presence of upper limb disorders was shown in a group of
workers. A sample of 42 people was selected for the study by means of specific tests: electromyography, ultrasonography and laser-doppler flowmetry. The tests showed a high incidence of carpal tunnel syndrome and microcirculation disorders.
The study confirmed that electromyography and ultrasonography are highly useful tools for identifying cumulative trauma disorders.
