Dermatologic Research Evaluation and Monitoring of Sleep in Moderate-to-Severe Psoriasis

PSG is the gold standard for objectively measuring sleep in the laboratory setting. The procedure consists of electrodes measuring brain activity (electroencephalography, EEG), eye movements (electrooculography, EOG), muscle activity (electromyography, EMG), respiratory events, snoring activity, blood oxygen saturation, and body position. Video surveillance during the sleep study can also monitor for itching events that occur during the night.
