A study was conducted of vibration exposed workers to determine the findings of aesthesiometry, photocell plethysmography, and radiographic testing on these workers. Aesthesiometry tests confirmed a diagnosis of advanced stages of vibration syndrome. Because false positives and false negative can occur, the results of these tests should not override the judgement of the physician. The data gathered in the plethysmography tests indicated an association between the presence of vibration syndrome and prolonged recovery time of the blood flow after immersion of the opposite hand in ice water. However, the results were inconclusive due to the small number of subjects studied, and the researchers questioned the usefulness of this test in the clinical diagnosis of vibration syndrome. Radiographic diagnostic procedures examined the prevalence of cysts in the hand and wrist bones of a vibration exposed group and a comparison group of manual workers from the same environment. There was no statistically significant difference in the prevalence of bone cysts in the two populations.
