Baseline | Experimental Mechanical Nociceptive Pressure Stimulus | Short Term Pain Memory | Long Term Pain Memory or Visualization |
Quiet supine resting (both groups) | Maximum tolerable mechanical pressure pain (both groups) | Memory of maximum tolerable pressure pain (both groups) | Memory of previous substantial injury or visualization of lower extremity |
| Clustered. Mechanical nociceptive pressure pain always preceded short term pain memory |
