Sciatic nerve injury caused by a stretching exercise in a trained dancer.

Area of Science:

• Neurology
• Sports Medicine
• Rehabilitation

Background:

• Sciatic nerve injury from stretching exercises is uncommon.
• Dancers are susceptible to various musculoskeletal injuries due to intense training.

Purpose of the Study:

• To report a rare case of sciatic nerve injury in a trained dancer following routine stretching.
• To investigate the mechanism and diagnostic findings of exercise-induced sciatic neuropathy.

Main Methods:

• Case report of an 18-year-old female dancer.
• Clinical examination, electrodiagnostic tests (nerve conduction studies, electromyography), and magnetic resonance imaging (MRI).
• Follow-up assessments at 3, 5, and 12 months post-injury.

Main Results:

• The patient developed right sciatic neuropathy, primarily affecting the tibial division, with foot dysesthesia and weakness.
• MRI revealed a partial tear of the left hamstring origin and fluid collection, but no direct sciatic nerve injury on the left.
• Electrodiagnostic tests confirmed sciatic neuropathy from the gluteal fold to the distal tibial area.
• Significant recovery of motor weakness and evidence of axonal regeneration were observed over 12 months.

Conclusions:

• Routine stretching exercises, particularly involving hyperstretching, can lead to sciatic nerve injury, even without direct compression.
• Prompt diagnosis using electrodiagnostic studies and imaging is crucial.
• Rehabilitation therapy and monitoring for axonal regeneration are key to recovery in such cases.
