Assessment of Spinal Nociception Laboratory

Assessment of Spinal Nociception Laboratory

Head of Laboratory: Ole Kæseler Andersen, Professor (OKA)

Aim

The aim of the lab is to assess and modulate spinal nociception in humans. The nociceptive withdrawal reflex is investigated in detail for understanding reflex pathways, reflex modulation, and as a biomarker for probing spinal nociception. Surrogate models for spinal sensitisation are developed.

                                 

Assessment of the organisation of nociceptive withdrawal reflexes in the lower limb involve several stimulation sites on the sole of the foot. Typical reflex size distribution for the tibialis anterior muscle is depicted on the right.
 

Main Research Areas

  1. The nociceptive withdrawal reflex - Probing spinal nociception
    The spinal organization of withdrawal reflexes receives substantial attention in the lab. Methods for quantifying the reflex receptive field (RRF) are constantly in focus. The RRF technique is utilized to study spinal nociceptive processing in models of central sensitization and in patients. The influence of descending control is evaluated, e.g. by studying reflexes in spinal cord injured volunteers.
  2. Models of cutaneous hyperalgesia and Long Term Potentiation (LTP):
    New models are developed and sensory characteristics of existing models are evaluated. Both sensory and vascular measures are assessed by state-of-the art cutaneous stimulators and imaging techniques for evaluating peripheral and central mechanisms.
