Figure 10. LEMG Patterns Associated with Brief Adduction During Respiration.

Figure 10

Characteristic LEMG firing patterns at 4 months that correlated with videolaryngoscopy findings of an adductor twitch during respiration. Gray shaded area demarcates the inspiratory PCA recruitment with giant motor units (3+), while the solid arrow denotes a burst of increased firing activity in the TA with relatively little antagonistic firing from the PCA, leading to brief adduction during inspiration. The PCA was characteristically silent between inspiratory firing, while the TA demonstrated continuous firing at baseline.
