Can a structural leg length discrepancy contribute to persistent concussion symptoms? A case report

Area of Science:

• Neurology
• Vestibular Science
• Sports Medicine

Background:

• Concussions and post-concussion syndrome (PCS) are increasingly recognized but lack clear physiological explanations and effective treatments.
• The vestibular system, crucial for balance and eye movements, is often disrupted in PCS, causing symptoms like dizziness and nausea.
• A potential link between structural leg length discrepancy and ongoing vestibulo-ocular/cervical-ocular disruption in PCS has not been previously explored.

Purpose of the Study:

• To describe a case of PCS with a previously unreported contributing factor: structural leg length discrepancy.
• To investigate the role of vestibulo-ocular/cervical-ocular disruption in PCS.
• To present a treatment approach combining conservative management of leg length discrepancy and vestibular rehabilitation.

Main Methods:

• A case study of a patient diagnosed with PCS.
• Assessment and conservative treatment of a structural leg length discrepancy.
• Implementation of vestibulo-ocular and cervical-ocular rehabilitation protocols.

Main Results:

• The patient presented with symptoms consistent with PCS, including dizziness and balance deficits.
• Conservative treatment of the structural leg length discrepancy was initiated.
• Subsequent vestibulo-ocular/cervical-ocular rehabilitation was performed.

Conclusions:

• Structural leg length discrepancy may be an unrecognized factor contributing to vestibulo-ocular/cervical-ocular disruption in PCS.
• A combined treatment approach addressing both the leg length discrepancy and vestibular dysfunction may be beneficial for PCS patients.
• Further research is warranted to explore this novel association and treatment strategy in post-concussion syndrome.
