lead to increased morbidity and mortality, representing a significant public health concern in the older population. Head protection designed and sold to older adults does not require certification, resulting in a wide range of head protection designs, which in return creates a wide range of safety. Certified helmets, including hockey and cycling helmets, provided superior protection across all tested impact conditions. Two head protection prototypes for older adults were developed for this study using rotational technology. Two commercially available head protectorsfor older adults, two prototype head protectors, a certified hockey helmet and a certified cycling helmet were impact tested. Peak resultant linear and rotational acceleration values varied for the commercial head protectors and prototypes depending on the impact test conditions. Even with the incorporation of rotational technology, Prototype One resulted in inconsistent performance in reducing rotational acceleration. Prototype Two included two rotational technologies, resulting in decreased rotational acceleration for all conditions, with the highest reduction being 55% at 5.0 m/s front impact and 61% at 5.0 m/s rear impact. While the older adult head protection prototypes did reduce linear acceleration, on average, they did not perform as well as the two certified helmets. Even though the certified sports helmets were specifically designed and certified for other activities (hockey and cycling), on average, they performed better in all conditions when compared to the two prototype helmets. These findings support the value of employing a certification standard for older adult headgear. While the prototypes showed potential, the adoption of an older adult headgear standard would support head gear innovation and decrease head injuries among the older population.
