Rapid screening for peripheral neuropathy: a field study with the Optacon.

J C Arezzo, H H Schaumburg, C A Petersen

    Neurology
    |May 1, 1983
    PubMed
    Summary

    The modified Optacon effectively screens for peripheral nerve dysfunction by measuring fingertip vibration. This simple device detected subclinical neuropathy in acrylamide-exposed individuals, proving its utility in occupational health.

    Area of Science:

    • Neuroscience
    • Occupational Health
    • Biomedical Engineering

    Background:

    • Acrylamide exposure is a known risk factor for peripheral neuropathy.
    • Early detection of nerve dysfunction is crucial for intervention.
    • Existing screening methods may have limitations in accessibility or cost.

    Observation:

    • A modified Optacon, a portable device measuring fingertip vibration sensation, was utilized.
    • Para-professionals screened 257 individuals with occupational acrylamide exposure.
    • Data consistency was confirmed through repeated individual testing.

    Findings:

    • A linear, age-related decline in vibration sensitivity was observed in the study population.
    • The modified Optacon successfully identified subclinical peripheral neuropathy in two individuals.

  • One case of neuropathy was linked to acrylamide exposure, the other to nutritional-alcoholic factors.

    • Implications:

    • The modified Optacon serves as a viable and reliable screening tool for peripheral nerve dysfunction.
    • This device can aid in the early detection of occupational neuropathy.
    • The findings support the use of vibration sensation testing in routine health surveillance programs.
