Three weeks of continuous positive airway pressure (CPAP) therapy significantly reduced fatigue and increased energy in patients with obstructive sleep apnea (OSA), according to a new study.
Researchers at San Diego State University (SDSU; CA, USA) and the University of California San Diego (UCSD; USA) conducted a double-blind study which randomly assigned 59 men and women with OSA to therapeutic or placebo CPAP for a 3-week intervention period. The researchers assessed four outcome measures; fatigue/vigor measured with the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-sf); both fatigue and vigor subscales of the Profile of Mood States-Short Form (POMS); and the Epworth Sleepiness Scale (ESS). Questionnaire data were obtained prior to study randomization and after the three-week intervention period.
