Summary

A cyclist developed bilateral sacral radiculopathy, a rare gait disorder, after intense exercise. Symptoms improved over time, suggesting potential pathogenic mechanisms like compression or ischemia in athletes.

Area of Science:

  • Neurology
  • Sports Medicine
  • Physical Therapy

Background:

  • Gait disorders can arise from various neurological conditions.
  • Radiculopathy, affecting nerve roots, can manifest as weakness and sensory changes.

Observation:

  • A case report details a patient experiencing bilateral sacral radiculopathy following vigorous cycling.
  • Symptoms included rapid, painless leg weakness, particularly in foot and knee flexors.
  • Electromyography indicated acute denervation with mixed reinnervation in S1 muscles; MRI was normal.

Findings:

  • The patient was diagnosed with subacute bilateral S1 radiculopathy.
  • Clinical and neurophysiological parameters showed progressive improvement.
  • This condition is infrequent in cyclists, with external compression being a common cause.

Implications:

  • Speculative pathogenic mechanisms include nerve elongation, compression, and secondary ischemia.
  • This case highlights a potentially novel presentation of S1 radiculopathy related to compressive lesions in athletes.
  • Further research into exercise-induced radiculopathy in sportsmen is warranted.
