Legend of the picture:
Examining differences in neural correlates of pain facilitatory and inhibitory mechanisms between acute low back pain patients and healthy individuals was the aim of this study. Pressure pain tolerance, electrical pain detection thresholds, pain ratings to repetitive suprathreshold electrical stimulation and conditioned pain modulation were assessed in 18 patients with acute low back pain and 18 healthy controls. This article presents evidence that acute low back pain patients show enhanced pain facilitation and unaltered pain inhibition compared to pain-free volunteers.
