This study showed that youth with concussion may benefit from some smartphone or TV use, rather than avoiding screen time completely.
Study Overview
Researchers at Nationwide Children's Hospital have published a significant study in the British Journal of Sports Medicine suggesting that moderate screen time after a concussion may actually be associated with faster recovery—directly challenging previous guidance that recommended total screen avoidance.
The study focused on youth aged 11-17 with physician-diagnosed concussion. Unlike prior research that relied on self-reporting, this study objectively measured screen time using a wearable device during the first week following injury.
Key Findings
A median of 141 minutes of screen time per day over the first three days was associated with a 35% faster recovery compared to 260 minutes per day.
The relationship between screen time and recovery followed a U-shaped pattern:
- Screen time exceeding four hours per day was linked to slower symptom resolution.
- Screen time less than two hours per day was also linked to slower symptom resolution.
"These findings support that moderate screen time – not too little or too much – may support concussion recovery." — Lead author Jingzhen Ginger Yang, PhD, MPH
Type of Screen Activity Matters
Researchers found that not all screen time is equal when it comes to concussion recovery:
- Around two hours per day of smartphone use and TV viewing were associated with quicker recovery.
- Computer/tablet use and gaming were not significantly related to faster symptom resolution.
Co-author Thomas Pommering, DO, noted: "This study showed that youth with concussion may benefit from some smartphone or TV use, rather than avoiding screen time completely or overusing screens in the days following a concussion."
Implications for Care
- Pediatricians may now consider recommending a balanced level of screen time immediately after concussion, rather than total avoidance.
- Monitoring both quantity and type of screen use—potentially with wearable technology—may aid recovery.
- Clinical trials are still needed to determine optimal screen time amounts and specific beneficial activities for concussion recovery.
- Families are advised to collaborate with their child's care team for individualized recovery plans.
Background
This research was conducted by experts at Nationwide Children's Center for Injury Research and Policy and the division of Sports Medicine. The study represents a significant departure from previous medical guidance, which traditionally recommended complete avoidance of screens after concussion.
