A note on the deep abdominal reflex.

R D Teasdall, H van den Ende

    Journal of Neurology, Neurosurgery, and Psychiatry
    |April 1, 1982
    PubMed
    Summary

    Deep abdominal reflexes in upper motor neuron lesion patients are bilateral and rapid. These responses are likely independent stretch reflexes, not crossing the spinal cord midline.

    Area of Science:

    • Neuroscience
    • Human Physiology
    • Clinical Neurology

    Background:

    • Upper motor neuron (UMN) lesions affect voluntary motor control.
    • Abdominal reflexes are clinically used to assess neurological function.
    • The neural pathways mediating abdominal reflexes are not fully elucidated.

    Purpose of the Study:

    • To investigate the characteristics of deep abdominal reflexes in patients with UMN lesions.
    • To determine the latency and symmetry of electromyographically recorded abdominal muscle responses.
    • To postulate the underlying neural mechanisms of these reflexes.

    Main Methods:

    • Electromyography (EMG) was used to record deep abdominal reflexes.
    • Six patients with diagnosed upper motor neuron lesions participated.
    • Response latencies and bilaterality were analyzed.

    Main Results:

    • Bilateral abdominal muscle responses were consistently observed.
    • Response latencies ranged from 16.5 to 25 ms.
    • Individual latency variation was minimal (≤ 2 ms).

    Conclusions:

    • Bilateral abdominal reflexes in UMN lesions are likely independent stretch reflexes.
    • These reflexes are probably not mediated via an intraspinal pathway crossing the midline.
    • Findings suggest localized reflex arcs in abdominal muscle response.
