Brief Summary

Massage is a common rehabilitation treatment for musculoskeletal pain. Prior studies indicate massage applied with a deep pressure that induces a moderate amount of pain produces a lessening of pain sensitivity compared to light touch, pain free massage. The investigators now aim to investigate how long pain sensitivity changes last after 4 minutes of moderately painful massage and determine factors that help predict who displays a lessening of pain sensitivity.

Conditions

Healthy; Pressure Pain Threshold; Massage

Outcome Measures

Primary Outcomes (1)

• Change in Pressure Pain Threshold

  A digital pressure algometer will be applied to the web space of the foot opposite the trigger point. Participants are instructed to say "stop" or "pain" so the stimulus can be terminated "when the sensation first transitions from pressure to pain" (pain threshold). Participants will rate the pain experienced during the threshold testing using a 101-point numeric pain rate scale (NPRS) anchored with 0= no pain to 100= the most intense pain sensation imaginable immediately following each testing time.

  PPT is applied between minutes 1, 2, 3, and 4 of massage. PPT is also applied at minutes 1,3,5,10,15 after massage. A higher PPT indicates a lessening of pain sensitivity.

Secondary Outcomes (2)

• Temporal Summation

  Applied before massage

• Conditioned Pain Modulation

  Applied before massage

Study Arms (1)

Moderately Painful Massage

EXPERIMENTAL

Participants will be seated in a chair with his or her shirt on. Participants will receive 60 seconds of manual pressure applied to the myofascial trigger point identified in the participant's upper back. The researcher's thumb or index finger will apply a deep manual pressure such that the participant rates the pain = 50/100 on a 101-point numeric pain rating scale with 0 indicating no pain and 100 indicating the most severe pain imaginable. The participant will be asked to rate his or her pain during the massage so the pressure may be adjusted to maintain the 50/100 related pain. Massage will be applied for 60 seconds, 4 times for a total contact time of 240 seconds. During each 30 second break in which manual pressure is released, Pressure Pain Threshold (PPT) to the foot will be examined. PPT will be assessed 2 times immediately after each of the 4 massage applications.
