Utilizing the Quantitative Electroencephalograph (qEEG) to Objectively Document the Nature and Severity of...

Concussions represent a major concern for hockey teams. During one winter season, all players on two Junior Hockey Teams were assessed in order to establish an incidence baseline for concussions. The qEEG was utilized as it measures the probability of concussion and its severity. The SCL 90-R and CNS questionnaire were used to provide insight into various aspects of cognitive functioning. Results indicated that of the players assessed (N = 46) approximately two-thirds (N = 32) tested positive for concussions. A minority of the concussions were assessed as mild (N = 13), while 19 were assessed as moderately severe. The most common sites indicated as injured were F8 and T6 (right side of head) and O1 and O2 (back of head) and F7 (left front of head). A comparison of the questionnaire results to expected behavioural issues are discussed. This appears to be one of the first studies of junior hockey players using an objective measure of study (qEEG).
