“Mechanisms of Massage”
The investigators have previously found moderately painful massage produces comparable changes in pain sensitivity as a conditioned pain modulation paradigm in healthy participants suggesting shared underlying mechanisms. The researchers aim to extend these findings by understanding the influence of expectation on these findings.
Pain Inducing Massage
A pain inducing massage (pain intensity = 50/100) will be applied for 60 seconds, 4 times.
Pain Free Massage
A pain free massage (pain intensity = 0/100) will be applied for 60 seconds, 4 times.
Positive Expectation Instructional Set
Participants will be instructed that the massage is effective for some people with neck pain.
Negative Expectation Instructional Set
Participants will be instructed that the massage is ineffective for some people with neck pain.
