Screen Time After Concussion: A Surprising Path to Faster Recovery?

Moderate screen time during the first three days after a concussion is associated with faster symptom resolution in adolescents, according to a study published in the British Journal of Sports Medicine.

Key Findings

The study tracked 80 concussed adolescents aged 11 to 17 years, monitoring them until symptom resolution or up to 45 days. Screen time was measured using a wearable camera that captured images every 30 seconds.

Average screen time during the first week after injury was 358.4 minutes per day. After adjusting for factors, an average of 141 minutes of daily screen time during the first three days was associated with a 35% faster rate of symptom resolution than an average of 260 minutes.

The results showed a clear pattern:

  • Symptom resolution was more than twice as fast among teens with 120–240 minutes of daily screen time compared to those with less than 120 minutes.
  • And 1.5 times faster than those with more than 240 minutes.

Screen Type Matters

Not all screens are equal in their effect on recovery.

Smartphone use of 120–240 minutes per day was associated with more than twice the symptom resolution rate compared to either less or more usage.

TV watching of 60–120 minutes per day was associated with three times the resolution rate compared to more than 120 minutes.

Notably, computer/tablet use and gaming were not significantly associated with faster recovery.

Study Limitations

Researchers are careful not to overstate their findings:

  • Observational study: No causal conclusions can be drawn.
  • Small sample size: Screen content, brightness, resolution, color settings, and cognitive engagement were not measured.
  • Missing data: Screen use during school hours and timing were not recorded.
  • Researchers call for standardized definitions, uniform measurement, and randomized controlled trials to confirm these results.

Clinical Takeaway

Rather than recommending complete screen avoidance, clinicians may suggest a daily screen time target of about 141 minutes to support recovery from concussion in adolescents.
