Temporal Summation of Pain Is Not Amplified in a Large Proportion of Fibromyalgia Patients

Figure 1

Temporal summation of heat pain fibromyalgia patients and healthy controls. This figure depicts the time course of pain perception during the tonic thermal noxious stimulation in fibromyalgia (FM) patients (open circles) and healthy controls (HCs) (black lines). We can clearly see that HCs have more pain at the end of the curve (temporal summation) when compared to FM patients; error bars refer to standard errors.
