Key result
Beta event-related spectral perturbation over central channels significantly correlated with error rates during a sustained attention task with painful stimuli (R=0.54, P=0.03).
Why the study?
Does sustained attention to pain affect EEG activity and vigilance behaviors in healthy participants?
Population
16 healthy participants (10 men, 6 women, aged 22-57 years)
Comparison
Sustained Attention protocol counting painful… vs First vs Second Interval of the task
Design
Task order randomly assigned and counterbalanced across subjects

Hypothesis-generating for beta-linked vigilance lapses in experimental pain; leaves open translation to clinical populations or interventions.
Does sustained attention to pain affect EEG activity and vigilance behaviors in healthy participants?
Effect estimate: R=0.54
p-value: p=0.03
Sustained attention to pain modulates EEG Beta activity, which correlates with performance errors, suggesting a neural mechanism for vigilance decrement to pain.
Chien et al. (2017) studied Healthy (acute pain model) (n=16). Continuous Performance Task (CPT) with painful laser stimuli vs. First Interval vs Second Interval (time on task) was evaluated on Correlation between Window IV Beta ERS and Error Rates (R=0.54, p=0.03). Beta event-related spectral perturbation over central channels significantly correlated with error rates during a sustained attention task with painful stimuli (R=0.54, P=0.03).
