J Head Trauma Rehabil. June 2021


Who participated in this study?

Three groups of 40 ice hockey players, aged 11-17 years.

  1. No concussion
  2. Recent concussion
  3. History of concussion

When did this study occur?

2013-2018

Why did we do this research?

To assess intrarater reliability. To assess the utility of a prism paradigm to identify sensorimotor impairment following sports-related concussion in youth compared with youth with no concussion.

What did we find?

The prism paradigm has the potential to alter concussion management in youth when used as a clinical measurement tool.

Changes in exertion-related symptoms in adults and youth who have sustained a SRC

Rutschmann TD, Miutz LN, Toomey CM, Yeates KO, Emery CA, Schneider KJ

J Sci Med Sport. January 2021


Who participated in this study?

45 individuals, aged 13-57 years

When did this study occur?

December 2017-August 2018

Why did we do this research?

To identify symptoms responsible for cessation of exercise testing. To evaluate changes in post-concussion symptom scores on the Post-Concussion Symptom Scale at difference time-points following the completion of the Buffalo Concussion Treadmill Test.

What did we find?

Evidence suggests individuals who experience an exacerbation of concussion-associated symptoms after exertion are likely to return to pre-exertion levels within the same day.

The Association of Saliva Cytokines and Pediatric Sports-Related Concussion Outcomes

Seeger TA, Tabor J, Sick S, Schneider KJ, Jenne C, Parker L, Talai AS, Rajashekar D, Mouches P, Forkert ND, Emery CA, Debert CT

J Head Trauma Rehabil. September/October 2020


Who participated in this study?

Youth ice hockey participants, aged 12-17 years.

When did this study occur?

2013-2016

Why did we do this research?

To explore cytokine alterations following pediatric sports-related concussion. To explore whether a specific cytokine profile could predict symptom burden and time to return to sports.

What did we find?

There is evidence of saliva cytokine profiles associated with increased symptom burden. Further studies are needed.

Association between concussion education and concussion knowledge, beliefs and behaviours

Black AM, Yeates KO, Babul S, Nettel-Aguirre A, Emery CA

BMJ Open. August 2020


Who participated in this study?

786 Parents and 10 non-parent coaches of youth ice hockey players.

When did this study occur?

2015-2016 ice hockey season.

Why did we do this research?

To examine the association between self-reported exposure to concussion education and knowledge, beliefs and self-reported behaviour among parents and coaches of youth ice hockey players.

What did we find?

Exposure to concussion education may be associated with small overall differences in concussion knowledge. It may not be associated with significant differences in beliefs or intended behaviours related to concussion management.

The Association Between Moderate and Vigorous Physical Activity and Time to Medical Clearance to RTP

Lishchynsky JT, Rutschmann TD, Toomey CM, Palacios-Derflingher L, Yeates KO, Emery CA, Schneider KJ

Front Neurol. June 2019


Who participated in this study?

30 youth ice hockey players, aged 12-17 years, who were diagnosed with a concussion during ice hockey.

When did this study occur?

During the 2015-2016 ice hockey season

Why did we do this study?

To evaluate the association between the amount of moderate and vigorous physical activity during the first three days following concussion and the time to medical clearance to return to play.

What did we find?

This study suggests that greater amounts of moderate to vigorous physical activity in the recovery period may result in greater time to medical clearance.
