  1. 01HumanRandomized controlled trialEfficacy outcome

    In adults with chronic neck and shoulder pain and in pain-free controls, intranasal oxytocin did not change resting heart rate variability.

    In plain wordsIn adults with and without chronic neck and shoulder pain, intranasal oxytocin did not change resting heart rate variability compared with placebo.

    Participants included 24 individuals with chronic neck and shoulder pain lasting >12months and 24 age- and sex-matched pain-free controls.
    Summary · context
    In a randomised double-blind, placebo-controlled, cross-over study, participants self-administered intranasal oxytocin (24IU) in one session, and placebo in another, before HRV was recorded at rest and during a mental arithmetic task.
  2. 02HumanRandomized controlled trialEfficacy outcome

    In adults with chronic neck and shoulder pain and in pain-free controls, intranasal oxytocin produced small decreases in low-frequency HRV during a mental arithmetic task compared with placebo.

    In plain wordsIn adults with and without chronic neck and shoulder pain, intranasal oxytocin slightly lowered one heart rate variability measure during mental arithmetic compared with placebo.
