Phantom and amputation illusions in paraplegic patients

T M Ettlin, W Seiler, H E Kaeser

    European Neurology
    |January 1, 1980
    PubMed
    Summary

    Amputation illusions and anosognosia with phantom limb position are distinct in paraplegic patients. Spinal cord injury with brain concussion causes amputation illusions, while conscious trauma leads to awareness of limb position.

    Area of Science:

    • Neuroscience
    • Clinical Neurology

    Background:

    • Paraplegic patients often experience sensory disturbances following spinal cord injury.
    • Understanding these phenomena is crucial for patient care and rehabilitation.

    Observation:

    • Amputation illusions and anosognosia with phantom position illusions are distinct neurological events.
    • These phenomena do not occur concurrently in the same patient.

    Findings:

    • A permanent amputation illusion is consistently observed after complete spinal cord injury combined with brain concussion.
    • Patients who remain conscious during spinal trauma retain awareness of their paralyzed limbs' positions, linked to the body's position at injury.

    Implications:

    • Differentiates between two distinct sensory disturbances in paraplegia.
    • Highlights the role of consciousness and brain injury in the manifestation of these illusions.
    • Informs clinical assessment and therapeutic strategies for individuals with spinal cord injuries.
