Subsymptomatic Aerobic Exercise for Patients With Postconcussion Syndrome: A Critically Appraised Topic

Area of Science:

• Neurology
• Sports Medicine
• Rehabilitation

Background:

• Postconcussion syndrome (PCS) affects patients experiencing concussion symptoms longer than 4 weeks.
• Aerobic exercise is known to improve general physical and mental health.
• Emerging evidence suggests aerobic exercise may aid PCS recovery by increasing patient activity and reducing isolation.

Purpose of the Study:

• To determine if aerobic exercise is more effective than standard care for reducing symptoms in patients with prolonged concussion symptoms or PCS exceeding 4 weeks.

Main Methods:

• A literature search identified 4 relevant studies: 1 randomized controlled trial and 3 case series.
• All studies examined aerobic exercise protocols as a treatment for PCS.
• Protocols like the Buffalo Concussion Treadmill test were used to guide exercise intensity and track progress.

Main Results:

• Three studies reported greater symptom improvement with controlled subsymptomatic aerobic exercise compared to baseline.
• One study indicated that aerobic exercise reduced symptoms more effectively than full-body stretching.
• Moderate evidence supports aerobic exercise as a beneficial treatment for PCS.

Conclusions:

• Subsyptomatic aerobic exercise is a viable clinical option for managing PCS and prolonged concussion symptoms.
• Validated protocols are essential for measuring baseline values and monitoring treatment progression.
• Aerobic exercise demonstrates potential to be more effective than current standard care for PCS treatment.
