简要总结
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.

结局指标
主要结局
Change in Pressure Pain Threshold
时间窗: 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.
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.
