Primary Outcome Measures

Name	Time	Method
Perceived exertion rating (Borg Scale)[baseline (pre-intervention), 10, 20 and 30 minutes post-intervention.];EMG muscle activity (amplitude, mean frequency) in erector spinae, internal obliques, gluteus medius[A ten (10) second record trial will be collected at baseline (pre-intervention), 10, 20 and 30 minutes post-intervention.]

Secondary Outcome Measures

Name	Time	Method
Pain Rating Scale (Visual Analog Score)[baseline (pre-intervention) and 10, 20 and 30 minutes post-intervention];Brush Allodynia Score. Brush allodynia testing will be done to validate the presence of secondary hyperalgesia (central sensitization). The Brush Allodynia Score is defined as the linear distance from the treatment area (capsaicin, placebo cream) to the outer border of the skin characterized by secondary hyperalgesia.[baseline (pre-intervention) and 10, 20 and 30 minutes post-intervention.]
