About this trial
This study is interested in whether baseline measures of pain sensitivity i.e. the amount of pressure required to feel pain predicts pain relief following a pain inducing massage AND whether pain relief following a pain inducing massage is different than a pain free massage or placing your hand in a cold water bath. Participants with neck pain will be randomly assigned to receive a pain inducing massage, pain free massage, or to place their hand in a cold water bath.

Treatments tested in this trial
Pain Inducing Massage
Procedure/Surgery60 seconds of direct pressure to the neck resulting in 5/10 pain . This will be repeated four times for a total of 240 seconds
Pain Free Massage
Procedure/Surgery60 seconds of direct pressure to the neck resulting in 0/10 pain . This will be repeated four times for a total of 240 seconds
Cold Water Bath
Procedure/SurgeryParticipants will place their hand in a cold water bath maintained at 6 to 8 degrees Celsius for 60 seconds. This will be repeated four times for a total of 240 seconds.
Treatment groups
Trial outcomes
Primary outcomes
Pressure Pain Threshold
Pressure applied to the web space of the foot with a digital pressure algometer applied at 1 kg/s. Participants will be instructed to indicate when the sensation first changes from pressure to pain (pain threshold)
Secondary outcomes
Numeric Pain Rating Scale Resting Pain
Participants will rate their "current" neck pain on a 0 to 100 scale with 0= no pain and 100= the most intense pain imaginable
Numeric Pain Rating Scale Movement Evoked Pain
Participants will rate their neck pain on a 0 to 100 scale with 0= no pain and 100= the most intense pain imaginable during active cervical spine range of motion. The average rating across all motions (flexion, extension, left and right sidebend, left and right rotation) will be used in the analysis.
