Playing with Legos During Initial Post-Concussion Rest Period
Light cognitive activities like Lego building are acceptable during the initial post-concussion period, provided they do not significantly exacerbate symptoms (no more than a 2-point increase on a 0-10 scale lasting less than an hour). 1
Initial Rest Period (First 24-48 Hours)
The most recent Amsterdam Consensus Statement (2024) and CDC guidelines establish that strict "cocooning" (complete physical and cognitive rest until symptom resolution) is not beneficial and may actually delay recovery. 1, 2
- More restrictive cognitive activity is recommended only during the first several days after concussion, not complete avoidance of all cognitive tasks. 2
- The evidence shows that brief, mild symptom exacerbation during cognitive activity is not harmful and does not delay recovery. 1
Practical Application to Lego Play
Lego building can be permitted if it meets the "subsymptom threshold" criteria:
- The activity should not increase symptoms by more than 2 points on a 0-10 scale. 1
- Any symptom increase should resolve within one hour. 1
- If symptoms worsen beyond these parameters, the child should take a break and resume when symptoms settle. 2
Important Caveats About Screen Time
- Reduced screen time is specifically recommended during the first 2 days post-concussion, as it facilitates recovery. 1, 3
- Traditional Lego building (non-electronic) would be preferable to video games or tablet-based activities during this acute period. 1
Evidence Nuances
The 2024 Amsterdam Consensus meta-analysis found that strict cognitive rest until complete symptom resolution may actually delay recovery, with early activity improving recovery by a mean of 4.64 days. 1, 3 However, one older study (2014) suggested increased cognitive activity was associated with longer recovery, though this contradicts more recent high-quality evidence. 4 The most recent guideline evidence should take precedence, supporting gradual cognitive activity that doesn't significantly worsen symptoms. 1, 2
After the First Few Days
Following the initial 24-48 hour period, patients should resume a gradual schedule of cognitive activities that does not exacerbate symptoms, with close monitoring of symptom number and severity. 2 Lego play would fit well within this graduated return to cognitive activity, as it can be easily adjusted in duration and complexity based on symptom response.
