Pain sensitivity and clinical pain changes occurring over 3 weeks. Clinical pain was assessed with a 101 point numeric rating scale anchored with 0= no pain and 100= the worst pain imaginable for “usual” pain over the past week. Participants were seen up to 6 sessions over the next 3 weeks to receive the NDI. After sensation includes only participants (n=12) reporting pain at 15 seconds following conclusion of the temporal summation protocol during baseline assessment. Measures of pain sensitivity and “usual” pain were again taken at the final session in 3 weeks. MP= mechanical pain sensitivity to 2.3 kg of force.
