Pain sensitivity changes assessed during the initial research session prior to and immediately following a neurodynamic intervention (NDI). Baseline clinical pain was assessed at the first visit when participants with signs and symptoms of CTS were asked to indicate their “usual” pain over the past week using a 101 point numeric rating scale anchored with 0= no pain and 100= the worst pain imaginable. Participants were seen up to 6 sessions over the next 3 weeks to receive the NDI. A measure of “usual” pain was again taken at the final session in 3 weeks. After sensation includes only participants (n=12) reporting pain at 15 seconds following conclusion of the temporal summation protocol. MP= mechanical pain sensitivity to 2.3 kg of force.
