The PCS measures negative thoughts and feelings associated with pain. The following table shows
the overall PCS scores. Both burst and tonic stimulation reduced the PCS score; however, neither
produced clinically meaningful changes on the PCS. Again, the reason for this observation may be
the relatively low baseline scores observed in the study population. The average baseline PCS
score of 20.4 was well below what is considered to reflect a clinically relevant level of pain
catastrophizing, which is a score that is more than 30 (Sullivan, 2009).
