The purpose of this study was to determine the immediate effect of 3 common physical therapy interventions for people experiencing low back pain on the perception of thermal pain. Additionally, the investigators wished to determine the influence of psychological factors related to fear and anxiety on their findings and to determine whether the effects of the individual interventions were local (specific to the area of application) or global (influenced regions away from the area of application).
