Self-Mobilisation Using a Foam Roller vs a Roller Massager For Increasing Hamstring Flexibility
Which is more effective?
This study explores the effectiveness of foam rollers and roller massagers in increasing hamstring flexibility among asymptomatic, physically active adults. It aims to determine whether moderate to high-quality evidence supports these self-mobilisation devices.
PMID: 27632826
Key Points
Aim: To assess the effectiveness of foam rollers and roller massagers in increasing hamstring flexibility in asymptomatic, physically active adults.
Methods: A literature review focused on randomised controlled trials. Four studies were included, two of which were for foam rollers and roller massagers.
Results:
Roller massagers: Both studies reported increases in hamstring flexibility after treatment.
Foam rollers: Data did not show statistically significant increases in hamstring flexibility, although one study demonstrated a strong effect size.
Practical Application
Roller massagers appear more effective than foam rollers for increasing hamstring flexibility.
Longer treatment duration and administration by a trained therapist may improve flexibility gains.
Flexibility gains tend to decline rapidly after rolling.
Neither device has been proven superior to static stretching for therapeutic benefits.
