• Are headaches common due to lacking conditioned pain modulation (CPM)?

    29 July 2019

    This question motivated Levy et al. to investigate the endogenous inhibition efficiency of the trigeminal and extra-trigeminal areas of the face, neck, and arm in healthy volunteers. Two TSA devices were used to allow thermal test and conditioning stimulation within these areas. CPM was tested in three different zones; 1) forehead (V1) and cheek (V3), 2) cheek and neck (C4), and 3) neck and arm (C7). Additionally, spatial summation of pain (SSP) and temporal summation (TS) of pain were tested on all four areas.

    Interestingly, the forehead was found to be least sensitive to heat pain, requiring the highest temperature to reach a VAS 5-6 pain rating. The only configuration that yielded a significant CPM response, was the neck and arm set-up, which did not involve any of the trigeminal sites. Spatial summation of pain was elicited in all four sites, and post-hoc analysis showed less spatial summation of pain in the forehead as compared to the other regions. Temporal summation of pain did not differ significantly between sites.

    This study showed inefficient pain modulation in trigeminal, as compared to extra-trigeminal areas. These findings could point to a possible factor in the etiology of pain syndromes involving the trigeminal area.

    To study CPM with two thermodes, you no longer need two TSAs, Our new TSA2, comes with standard dual-thermode abilities, allowing for advanced thermal stimulation protocols, with one portable device!

    QST identifies the better surgical skin graft technique:

    In a recent article published in the International Journal of Surgery, authors reported the use of a wide array of QST (quantitative sensory testing) techniques to identify which of three surgical flap techniques is the least damaging to sensory nerve function of the donor site.

    In this trial, which used Medoc’s TSA II and AlgoMed QST systems, thirty-one patients were included, by approximation equally divided among three types of surgical techniques. (more…)

    World Diabetes Day

    Diabetic neuropathy is one of the most common complications seen in patients suffering from diabetes worldwide, with rates of neuropathies seen in up to 50% of diabetic patients (Gordois et al., 2003a; Gordois et al., 2003b). Medoc has been developing different tools which, with the use of thermal and vibratory stimuli, are able to evaluate the type and level of impairment in different nerve fibers.

  • AlgoMed – High Level Technology for Pain Diagnosis

    31 October 2018

    Algometry has been used in the past decade for the detection of pressure pain threshold in different body sites, including bones, muscles and tendons. Patients with fibromyalgia, for instance, have been tested in clinical trials, attempting to quantify and characterize their pain through algometry. However, measurement tools adopted to test pain in fibromyalgia studies, for example, were based on the clinician’s impression of the patient’s state, thus not giving a precise measure (Cheatham et al., 2018).
