Table 2 Classification of disorder type. Classification of neuromusculoskeletal disorder type in the neck and upper extremities, origin of nociceptive disorder and further classification of a neurogen disorder for drivers of ATVs and for referents in this study. A subject diagnosed as having a nociceptive disorder could have several origins of pain (muscle, tendon, joint). Units in number of people if not stated. P-values for Fischer's exact test between driver categories and referents concerning the prevalence of asymmetrical and focal neuropathy.
