Study summary

The purposes of the study are to quantify and compare relationships among acute changes in inflammatory markers and evoked pain sensitivity after a high-fat meal (HFM) challenge, compared to a moderate-fat meal challenge, and explore the influence of body composition on these responses, in individuals with chronic spinal cord injury

What researchers measure

Primary outcomes

  1. peak change in Interleukin (IL)-6

    analysis of blood samples taken after ingestion of meal challenge for level of IL-6 in picograms/milliliter

    Time frame: at 40, 80, 160, 240, 320, and 400 minutes post meal ingestion

  2. peak change in evoked pain sensitivity

    measures of heat pain threshold (degrees Celsius), using the ascending method of limits via a 30mm2 surface thermode, obtained after ingestion of meal challenge

    Time frame: at 40, 80, 160, 240, 320, and 400 minutes post meal ingestion

Secondary outcomes

  1. correlation coefficient between changes in IL-6 and evoked pain sensitivity

    correlation coefficient for relationship between changes in IL-6 and heat pain thresholds across time

    Time frame: at 40, 80, 160, 240, 320, and 400 minutes post meal ingestion
