Study Supports Pediatric Concussion Management Approach

Children aged 5-12 years with concussion have similar recovery trajectories, regardless of whether the injury is linked to sports or to other causes, such as falls, new data indicated.

“With that result, it means we don’t need to change management protocols” depending on the cause of the concussion, study author Andrée-Anne Ledoux, PhD, a scientist at Children’s Hospital of Eastern Ontario Research Institute in Ottawa, Ontario, Canada, told Medscape Medical News. “That’s kind of good news. We’re applying the right management protocols with them.”

The data were published on December 4 in JAMA Network Open.

Secondary Analysis

The results stem from a planned secondary analysis of the prospective Predicting and Preventing Postconcussive Problems in Pediatrics study. Conducted from August 2013 to June 2015 at nine pediatric emergency departments in Canada, it included children of different ages (5 to

The secondary analysis focused on study participants who were aged 5-12 years and had presented within 48 hours of injury. The primary outcome was symptom change, which was defined as current ratings minus preinjury ratings, across time (1, 2, 4, 8, and 12 weeks), measured using the Post-Concussion Symptom Inventory.

No significant differences in postinjury recovery curves were found between participants with sport-related concussions (SRC) and those with non-SRC. The latter injuries resulted from causes such as falls and objects dropped on heads. SRC and non-SRC showed a nonlinear association with time, with symptoms decreasing over time.

Perhaps surprisingly, the researchers also reported a higher rate of persisting symptoms after concussion (PSAC) following limited contact sports than following contact sports such as hockey, soccer, rugby, lacrosse, and football. Limited contact sports include activities such as bicycling, horseback riding, tobogganing, gymnastics, and cheerleading.

This finding suggests that the management of SRC may not require distinct strategies based on sports classification, the researchers wrote. “Instead, it may be more appropriate for clinicians to consider the specific dynamics of the activity, such as velocity and risk of falls from heights. This nuanced perspective can aid in assessing the likelihood of persisting symptoms.” The researchers urged more investigation of this question. “A larger sample with more information on injury height and velocity would be required to confirm whether an association exists.”

In addition, the researchers cited guidelines that include a recommendation for a gradual return to low to moderate physical and cognitive activity starting 24-48 hours after a concussion at a level that does not result in recurrence or exacerbation of symptoms.

“Children do need to return to their lives. They need to return to school,” said Ledoux. “They can have accommodations while they return to school, but just returning to school has huge benefits because you’re reintegrating the child into their typical lifestyle and socialization as well.”

A potential limitation of the study was its reliance on participants who had been seen in emergency departments and thus may have been experiencing more intense symptoms than those seen elsewhere.

The researchers also excluded cases of concussion resulting from assaults and motor vehicle crashes. This decision may explain why they didn’t reproduce the previous observation that patients with SRC tended to recover faster than those with concussions from other causes.

Injuries resulting from assaults and motor vehicle crashes can involve damage beyond concussions, Ledoux said. Including these cases would not allow for an apples-to-apples comparison of SRC and non-SRC, she added.

‘Don’t Cocoon Kids’

The authors of an accompanying editorial wrote that the researchers had done “a beautiful job highlighting this important nuance.” Noncontact sports with seemingly little risk “actually carry substantial risks when one imagines the high-impact forces that can occur with a fall from height, albeit rare,” wrote Scott Zuckerman, MD, MPH, assistant professor of neurological surgery, and Douglas P. Terry, PhD, assistant professor of neurological surgery, both at Vanderbilt University Medical Center, and Jai Horsey, a research scholar at Meharry Medical College, all in Nashville, Tennessee.

The new analysis suggests a need to rethink a “somewhat archaic way of classifying sport risk, which may oversimplify how we categorize risk of brain and spine injuries.”

The commentary also noted how the researchers used the term PSAC to describe lingering symptoms instead of more widely used terms like “persistent postconcussive symptoms” or “postconcussive syndrome.”

“These traditional terms often connote a permanent syndrome or assumption that the concussion itself is solely responsible for 100% of symptoms, which can be harmful to a patient’s recovery,” the editorialists wrote. “Conversely, PSAC offers room for the clinician to discuss how other causes may be maintaining, magnifying, or mimicking concussion symptoms.”

Commenting on the findings for Medscape Medical News, Richard Figler, MD, an orthopedic surgeon at the Cleveland Clinic, Cleveland, praised the researchers for addressing concussion in younger children, a field in which little research has been conducted. The research supports the current approaches to treatment, he added. The approach has shifted toward easing children quickly and safely back into normal routines. “We don’t cocoon kids. We don’t send them to dark rooms,” Figler said.

He also commended the researchers’ decision to examine data about concussions linked to limited contact sports. In contact sports, participants may be more likely to anticipate and prepare for a hit. That’s not the case with injuries sustained in limited contact sports.

“Dodgeball is basically a sucker punch. That’s why these kids have so many concussions,” said Figler. “They typically don’t see the ball coming, or they can’t get out of the way, and they can’t tense themselves to take that blow.”
