Do helmets help protect against rotational brain injuries?

In-depth explanation

Traditional helmet tests focus on linear impacts, but rotational forces contribute significantly to brain injury. Technologies like MIPS and specially engineered liner constructions aim to reduce rotational acceleration in oblique impacts. While no helmet can eliminate all brain injury risk, MIPS and similar systems can reduce rotational forces and are a useful supplement to overall helmet safety.

Key takeaways

• Traditional helmet tests focus on linear impacts, but rotational forces contribute significantly to brain injury.
• Technologies like MIPS and specially engineered liner constructions aim to reduce rotational acceleration in oblique impacts.
• While no helmet can eliminate all brain injury risk, MIPS and similar systems can reduce rotational forces and are a useful supplement to overall helmet safety.
