Clinical Trial Summary

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 in participants with a history of neck pain.

Description:

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. Previous research has indicated pain inducing massage is more effective than pain free massage suggesting a mechanism dependent upon conditioned pain modulation. The study team will evaluate the association between pain inducing massage and the conditioned pain modulation paradigm. Participants with neck pain will be randomly assigned to receive a pain inducing massage, pain free massage, or a coldpressor task. Pre-and post intervention pain will be assessed. The study team will determine if analgesia induced by pain inducing massage is similar to the conditioned pain modulation paradigm and if baseline conditioned pain modulation predicts responders to pain inducing massage and short term clinical outcomes in patients with a history of neck pain.

Related Conditions & MeSH terms

• Musculoskeletal Pain
• Neck Pain

Intervention

Other:
• Pain Inducing Massage
Participants will receive 60 seconds of manual pressure applied to one myofascial trigger point so the participant rates the pain = 5/10 on a scale from 0 to 10. This will be followed by 30 seconds of complete pressure release. This will occur 4 times.
• Light Touch Massage
Participants will receive 60 seconds of light touch applied to one myofascial trigger point so the participant rates the pain = 0/10 on a scale from 0 to 10. This will be followed by 30 seconds of complete pressure release. This will occur 4 times.
• Coldpressor
Participants will place their non-dominant hand into water cooled by a refrigeration unit temperature of 6 degrees Celsius (males) or 8 degrees Celsius (females). The participant will place his or her hand in the cooled water for 60 seconds followed by a 30 second break in which the participant will remove his or her hand from the water. This will occur 4 times.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in Pressure Pain Threshold	Pressure in kilograms at which ascending pressure stimulus first changes from pressure to painful	2 hours
Secondary	Change from baseline in Thermal Pain Threshold and Tolerance	Temperature at which ascending thermal stimulus first changes from warm to painful and maximum temperature tolerated	2 hours
Secondary	Change from baseline in Pressure Pain Tolerance	Pressure in kilograms at which ascending pressure is no longer tolerated	2 hours
Secondary	Change from baseline in Ramp and Hold	Participants will rate their pain using a 101 point mechanical visual analog scale to thermal stimuli of 45, 47, 49, and 50 degree Celsius each of 5 seconds duration will be applied to the forearm and to the muscle on the side of the neck	2 hours
Secondary	Change from baseline in Temporal Summation	Participants will rate their pain using a 0 to 10 numeric rating scale to a train of 10 50 degree Celsius heat pulses will be applied to the skin in the plantar surface of the hand.	2 hours
Secondary	Change from baseline in Conditioned Pain Modulation	Pressure in kilograms at which ascending pressure stimulus applied to the foot first changes from pressure to painful both prior to and immediately following immersion of the opposite hand in a cold water bath	2 hours
