OBSERVATIONAL
Conditions
Summary
This case-control study aims to investigate the effects of occupational hand-arm vibration exposure on median and ulnar nerve functions in tattoo artists. Chronic exposure to vibration generated by tattoo machines may lead to neurosensory impairment, reduced tactile sensitivity, and decreased hand strength. Objective assessments including nerve provocation tests, sensory threshold evaluation, two-point discrimination, vibration perception, grip and pinch strength measurements, and validated patient-reported outcome questionnaires will be used. Findings will be compared with age- and sex-matched healthy controls.
