One in ten adults experience widespread pain. Neck pain, for example, is a prevalent
condition with a high rate of recurrence that affects between 10.4% and 21.3% of the
population annually.
Massage is a common manual therapy intervention for individuals with musculoskeletal pain.
However, the mechanisms of massage are not well established. Also, the conditioned pain
modulation (CPM) paradigm is a dynamic quantitative sensory testing measure of a pain
inhibitory process in which pain sensitivity is lessened in response to a remotely applied
painful stimulus.
This study will evaluate the association between pain inducing massage and the conditioned
pain modulation paradigm.

This study will evaluate the association between pain inducing massage and the conditioned

Conditioned pain modulation (CPM) is the physical manifestation of the diffuse noxious
inhibitory control (DNIC), an endogenous pain inhibitory pathway in which pain inhibits pain.
Conditioned pain modulation is less efficient in individuals with chronic pain conditions and
it is a predictor for the development of chronic pain.
Massage is a common manual therapy intervention for individuals with musculoskeletal pain.
Greater changes in pain sensitivity occur following pain inducing massage suggesting a
mechanism dependent upon the efficiency of the conditioned pain modulation response.
The study team will evaluate the association between pain inducing massage and the
conditioned pain modulation paradigm. Healthy participants will be randomly assigned to
receive a pain inducing massage, a pain free massage, or participate in a coldpressor task.
Pre-and post intervention pain sensitivity including conditioned pain modulation will be
assessed. The study team will determine if analgesia induced by massage is similar to the
conditioned pain modulation paradigm and compare changes in pain sensitivity between groups.
Previous research has indicated pain inducing massage is more effective than pain free
massage suggesting a mechanism dependent upon conditioned pain modulation. However, this
study will be the first to systematically investigate if analgesia induced by pain inducing
massage is similar to the conditioned pain modulation paradigm. Furthermore, this study will
be the first to determine the association between baseline conditioned pain modulation and
massage related hypoalgesia.
