Clinical application of sacral reflex latency.

W J Bilkey, E A Awad, A D Smith

    The Journal of Urology
    |June 1, 1983
    PubMed
    Summary

    Sacral reflex latency measurement is a novel electrophysiological test. It effectively differentiates neurological lesions, showing shorter latencies in upper motor neuron conditions and longer latencies in lower motor neuron impairments.

    Area of Science:

    • Neuroscience
    • Urology
    • Electrophysiology

    Background:

    • Sacral reflex latency is a key indicator of neurological function.
    • Distinguishing between upper and lower motor neuron lesions is crucial for diagnosis and treatment.

    Purpose of the Study:

    • To evaluate sacral reflex latency as a diagnostic tool for neurological lesions.
    • To compare sacral reflex latency in neurologically normal individuals and patients with motor neuron impairments.

    Main Methods:

    • Stimulating current applied to the glans penis or clitoris.
    • Measuring response with electrodes in external urethral and anal sphincters.
    • Assessing 108 normal subjects and 110 patients with neurological lesions.

    Main Results:

    • Normal men: mean latency 34.6 msec (urethral), 36.0 msec (anal).
    • Normal women: mean latency 37.4 msec (urethral), 38.6 msec (anal).
    • Significantly shorter mean latency in upper motor neuron lesions; increased mean latency in lower motor neuron impairment.

    Conclusions:

    • Sacral reflex latency measurement is a valuable electrophysiological test.
    • This test can differentiate between upper and lower motor neuron lesions.
    • It complements conventional electromyography and cystometry in diagnostics.
