Abstract:
Objective To investigate the features of peripheral nerve injuries in workers exposed to vibration.Methods A total of 197 male workers [median age:34 years (21-50 years);median working years of vibration exposure:7.3 years (1-20 years)] engaged in grinding in an enterprise were enrolled.Their clinical data and electromyography results were analyzed to investigate the features of peripheral nerve impairment.Results Of all workers,96 (48.73％) had abnormal electromyography results.Of all workers,88 (44.7％) had simple mild median nerve injury in the wrist,who accounted for 91.7％(88/96) of all workers with abnormal electromyography results.Six workers had ulnar nerve injury,superficial radial nerve injury,or/and superficial peroneal nerve injury and accounted for 6.3％ of all workers with abnormal electromyography results.Of all workers,88 had a reduced amplitude of median nerve sensory transduction,and 28 had slowed median nerve sensory transduction.A total of 46 workers were diagnosed with occupational hand-arm vibration disease and hospitalized for treatment.They were followed up for more than 4 months after leaving their jobs,and most of them showed improvements in neural electromyography results and returned to a normal state.Conclusion Workers exposed to vibration have a high incidence rate of nerve injury in the hand,mainly sensory function impairment at the distal end of the median nerve,and all injuries are mild peripheral nerve injuries.After leaving the vibration job and being treated,most workers can achieve improvements and return to a normal state.
