Correlation between a positive Hoffmann's reflex and cervical pathology in asymptomatic individuals

Area of Science:

• Neurology
• Spinal Cord Imaging
• Diagnostic Reflexes

Background:

• A positive Hoffmann's reflex typically indicates an upper motor neuron lesion, often due to spinal cord compression.
• The clinical significance of this reflex in asymptomatic individuals remains largely unestablished.

Purpose of the Study:

• To investigate the association between a positive Hoffmann's reflex and cervical pathology in asymptomatic patients.
• To assess the necessity of further diagnostic work-up in this specific patient group.

Main Methods:

• Prospective study of 16 asymptomatic patients with a positive Hoffmann's reflex.
• Utilized cervical radiographs and magnetic resonance imaging (MRI) for evaluation.
• Correlated imaging findings with detailed neurological examinations.

Main Results:

• All participants were asymptomatic, yet 87.5% showed cervical spondylosis on radiographs.
• MRI revealed pathology in all patients, with 94% exhibiting cervical cord compression from herniated discs.
• No treatment was initiated, and clinical outcomes remained unaffected.

Conclusions:

• A positive Hoffmann's reflex in asymptomatic individuals strongly suggests underlying cervical pathology.
• Despite high rates of detected cervical cord impingement, routine imaging is not warranted as it does not alter management or clinical course.
