Repetitive head impacts (RHI) are commonly observed in athletes participating in contact
sports such as American football, ice hockey, and soccer. RHI usually do not result in acute …

Competitive sport participation, in contact and collision sports, exposes athletes to repetitive
head impacts. Although these impacts do not always result in overt symptomology or a …

Repetitive head impacts (RHI) are a growing concern due to their possible neurocognitive
effects, with research showing a season of RHI produce white matter (WM) changes seen on …

Prior studies have reported white matter abnormalities associated with a history of
cumulative concussion and/or repetitive head impacts (RHI) in contact sport athletes …

Introduction Repetitive head impacts (RHI) sustained in contact sports are thought to be
necessary for the long-term development of chronic traumatic encephalopathy (CTE). Our …

Objective Repetitive subconcussive head impacts (RSHI) may lead to structural, functional,
