Self-Mobilisation Using a Foam Roller vs a Roller Massager For Increasing Hamstring Flexibility

Which is more effective?

Image created using Midjourney.

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

1. Roller massagers appear more effective than foam rollers for increasing hamstring flexibility.

2. Longer treatment duration and administration by a trained therapist may improve flexibility gains.

3. Flexibility gains tend to decline rapidly after rolling.

4. Neither device has been proven superior to static stretching for therapeutic benefits.

Key Takeaways

1. Grade B evidence supports using roller massagers to increase hamstring flexibility in asymptomatic, physically active adults.

2. Limited evidence exists for the effectiveness of foam rolling in increasing hamstring flexibility.

3. The effectiveness of these devices in preventing injury remains unknown.

4. More research is needed to determine the optimal duration and frequency of treatment for long-lasting flexibility gains.

This study looked into the effectiveness of self-mobilisation devices for improving hamstring flexibility. While roller massagers show promise, more research is needed to fully understand the long-term benefits and injury prevention potential of both foam rollers and roller massagers.
