Put down the electronics after a concussion?

Author and Disclosure Information

Yes, patients should do just that. In a randomized clinical trial, symptom duration was reduced when teens and young adults observed a certain screen-time hiatus.

PRACTICE CHANGER

Advise your teenaged and young adult patients with concussion to avoid electronic screens in the first 48 hours after a concussion to minimize time to symptom resolution.

ILLUSTRATIVE CASE

A 17-year-old high school football player presents to the emergency department (ED) after a helmet-to-helmet tackle in a game earlier that day. After the tackle, he experienced immediate confusion. Once he returned to his feet, he felt dizzy and nauseated and began to develop a headache. When his symptoms failed to resolve within a few hours, his mother brought him to the hospital for an evaluation. In the ED, he receives a diagnosis of concussion, and his mother asks for recommendations on how he can recover as quickly as possible.

Traumatic brain injuries account for an estimated 2.5 million ED visits annually in the United States.2 Concussions are the most common form of traumatic brain injury, with adolescents contributing to the highest incidence of concussions.3,4 An estimated 1.6 to 3.8 million people experience a sports-related concussion annually.5

Time to recovery is a clinical endpoint that matters greatly to our young, physically active patients, who are often eager to return to their daily activities as soon as possible. Guidelines frequently recommend cognitive and physical rest for 24 to 48 hours immediately following a concussion, but the use of screens during this cognitive rest period remains uncertain.6,7 International guidelines and the Centers for Disease Control and ­Prevention recommend symptom-limited activities—including screen time—during the initial period of a concussion.6,7 Although this gradual approach is standard of care, it has been unclear if abstaining completely from certain activities during the initial days of a concussion has any impact on recovery time.

Recent studies have examined physical activity to clarify the optimal timing of physical rest after a concussion. Among adolescents with concussions, strict rest for 5 days does not appear to improve symptoms compared with rest for 1 to 2 days.8 Additionally, physical activity within 7 days of acute head injury may help reduce symptoms and prevent postconcussive symptoms.9,10

This same level of clarity has been lacking for cognitive rest and screen time. The use of screens is a part of most patients’ daily activities, particularly among adolescents and young adults. One report found that students ages 8 to 18 years engage in approximately 7 hours of daily screen time, excluding that related to schoolwork.11 This trial evaluated the relationship between screen time abstinence within 48 hours of a concussion and time to symptom resolution.

STUDY SUMMARY

Symptom duration was significantly reduced by cutting screen time

This single-site, parallel-design, randomized clinical trial examined the effectiveness of limiting screen time exposure within the first 48 hours after a concussion in reducing the time to resolution of concussive symptoms in 125 patients. 1 Patients were included if they were 12 to 25 years old (mean age, 17 years) and presented within 24 hours of sustaining a concussion (as defined on the Acute Concussion Evaluation–Emergency Department tool) to the pediatric or adult ED at a US tertiary medical center.

A shared decision-making discussion should center on the idea that 48 hours of screen time abstinence could be well worth the increased likelihood of total recovery at Day 10.

Patients were randomized to either ­engage in screen time as tolerated or to abstain from screen time for 48 hours following their injury. Screen modalities included television, phones, video games, and computers/­tablets. The Post-Concussive Symptom Scale (PCSS; 0-132) was used to characterize 22 symptoms from 0 (absent) to 6 (severe) daily for 10 days. Patients also self-reported the amount of screen time they engaged in during Days 1 to 3 of the study period and completed an activity survey on Days 4 to 10. Among the participants, 76% completed the PCSS form until symptom resolution or until Day 10 (the end of the study period).
