Objective:

To investigate the relationship between out-of-school screen time and symptom resolution in youth recovering from concussion, specifically focusing on the first 3 days post-injury.

Key Findings:

• Moderate screen time (141 minutes per day) during the first 3 days post-concussion was associated with a 35% faster rate of symptom resolution compared to higher levels of screen time, with statistical significance noted.
• Youth with 120 to 240 minutes of screen time had faster symptom resolution than those with less than 120 or more than 240 minutes, though the latter comparison did not reach statistical significance.
• Smartphone use of 120 to 240 minutes per day was linked to faster recovery compared to lower or higher usage, with statistical significance.
• TV watching for 60 to 120 minutes per day was associated with faster symptom resolution compared to more than 120 minutes, with statistical significance.

Interpretation:

The study suggests that moderate screen time may support concussion recovery, but it cannot establish causation due to its retrospective design, small sample size, and potential biases.

Limitations:

• Small sample size (n = 80) may limit generalizability and the robustness of findings.
• Participants predominantly White and male, affecting broader applicability to diverse populations.
• Screen use during school hours was not measured, limiting the scope of the findings.
• Factors like screen content, brightness, and timing relative to sleep were not assessed, which may influence recovery.

Conclusion:

Further randomized controlled trials are needed to establish optimal screen time targets and determine the impact of different types of screen activities on concussion recovery, emphasizing the need for validation of these findings.
