Understanding Cognition, Oxytocin, and Pain in Elders (UCOPE): protocol for a double-blinded cross-over trial in chronic knee osteoarthritis pain

What Was Tested

Researchers studied Oxytocin in the context of chronic pain: fibromyalgia & crps in this clinical study publication.

The primary aims of the study are to examine preliminary analgesic effects of a chronic OT intervention in community-dwelling older individuals with chronic knee osteoarthritis pain.

Why It Was Studied

Osteoarthritis (OA) is the leading cause of disability among older adults with the knee being the most affected joint.

Specifically, there is an urgent need to develop better analgesics for individuals with OA-related pain, since currently used analgesics frequently fail to provide adequate relief or must be discontinued owing to adverse effects.

Who Took Part

The abstract describes 80 participants taking part.

By PubMed's age tags, the people studied were middle-aged adults and older adults, both men and women.

Primary study outcomes include preliminary changes in pain intensity and interference as well as multi-modal assessment batteries including circulating biomarkers and neuroimaging measures.

How the Study Was Run

The researchers set it up as a randomized, double-blind, placebo-controlled and crossover study.

Because people in this Oxytocin study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Blinding on both sides kept the participants and researchers unaware of who received Oxytocin.

Some participants received a placebo instead of Oxytocin, giving a reference point.

In the crossover set-up each of the participants took both Oxytocin and the comparison in turn, acting as their own control.

What Was Measured
