“…PPT was measured using a pressure algometer (Somedic AB, Farsta, Sweden) with a probe size of 1 cm 2 and application rate of 30 kPa/s in a perpendicular direction to the skin 20,21. The patients were instructed to press the button when the sensation under the probe changed from pressure to pressure and pain 22.…”

“…TDT and PDT were measured with a set of 20 calibrated Semmes–Weinstein monofilaments (Saehan, marking number 1.65–6.65; force 0.005–447 g) delivering a precise amount of pressure 20,21. To determine TDT and PDT, the method of limits was used, following a standardized protocol of five ascending and descending series 14.…”

“…Using the method of limits with suprathreshold and infrathreshold values, the geometrical mean was calculated. The number indicated in the monofilament was registered, corresponding to a logarithmic function of the applied force in grams 20,21. For TDT, the patient, with closed eyes, was instructed to indicate the detection of the touch of a monofilament.…”

BackgroundBased on inconsistent sensory alterations demonstrated in cluster headache (CH), the aim of this study was to determine whether patients with CH develop sensory changes in the symptomatic side compared to the asymptomatic side.MethodsQuantitative sensory testing (QST), including pressure pain threshold (PPT), tactile detection threshold (TDT), prick detection threshold (PDT), and two-point detection threshold (2PDT), was evaluated in 16 patients (seven women; age 41.9±6.8 years) with CH. Test sites included the first, second, and third divisions of the trigeminal nerve, cervical spine, and thenar eminence in the symptomatic and asymptomatic sides.ResultsThe symptomatic side, compared to the asymptomatic side, presented significantly decreased PPT in the first (P=0.011; 423.81±174.05 kPa vs 480.13±214.99 kPa) and second (P=0.023; 288.88±140.80 kPa vs 326.38±137.33 kPa) divisions of the trigeminal nerve, significantly increased TDT in the first (P=0.002; 2.44±0.40 vs 1.74±0.24) and second (P=0.016; 1.92±0.34 vs 1.67±0.09) divisions, and increased 2PDT in the first division (P=0.004; 18.13±4.70 mm vs 15.0±4.92 mm) and neck (P=0.007; 45.31±20.65 mm vs 38.44±16.10 mm).ConclusionThese results support the prior evidence suggesting a specific pattern of alteration of sensory function with alterations in the symptomatic side compared to the asymptomatic side.

Background: The diagnosis of temporomandibular disorders (TMD) is based on patient history and physical examination, and may require medical imaging. Masticatory muscle palpation is essential to make a diagnosis of TMD. However, the response of masticatory muscles to mechanical pressure stimuli depends on many physical and psychological factors. Objective: This study aimed at determining the impact of somatosensory amplification (SSA)-an estimate of somatic awareness and bodily hypervigilance-on pressure pain thresholds (PPTs) measured at both trigeminal and extra-trigeminal locations in healthy individuals. Methods: PPTs were measured at the right anterior temporalis and superficial masseter, and the thenar eminence of the right hand in one hundred healhty individuals (69F, 31M), divided in three groups based on their SSA scores: low (N = 32), intermediate (N = 34) and high (N = 34). General linear models were used to test betweengroup differences in PPTs including sex as a covariate. The level of significance was set at P < .05. Results: Individuals with high SSA had lower PPTs at the anterior temporalis than individuals with low (P = .006) and intermediate (P = .001) SSA. No significant betweengroup differences were found in PPTs measured at the masseter (P = .372). PPTs measured at the thenar eminence were significantly lower in the high than the low SSA group (P = .009). Females had lower PPTs at the masseter than males (P = .021) but not at other muscle locations (all P > .05). Conclusion: Increased somatosensory amplification is associated with decreased pressure pain thresholds at both trigeminal and extra-trigeminal locations in healthy individuals. SSA could be a potential confounder while diagnosing TMD and evaluating treatment outcomes.

“…In general, reports of age‐related decrements for the somatosensory senses (cooling, warming, touch and pain) are not consistent, and, in general, the varying results from the laboratory‐based studies reflect differences in methodologies employed, including varying types of stimuli employed to assess different modalities (e.g. contact thermal stimulation by Peltier devices or water immersion versus radiant heat for thermal assessments; vibratory, calibrated filaments or two‐point callipers for touch assessments; Peltier devices, radiant heat, water immersion, mechanical stimulation for pain assessments), variations in body regions, spatial area of skin exposed to thermal stimuli, variations in subjective measures that investigators assessed, such as threshold or suprathreshold measures and age range and maximum ages of the assessed individuals . Of note, Guergova and Dufour have reported that declines in thermal sensitivities are greater in the distal extremities than the proximal locations.…”

Somatosensory function in old age

Sensory decline is viewed as an inevitable consequence of the ageing process. However, reports of declines have not been a consistent finding across the sensory systems. Reports from psychophysical studies indicate that the most common declines with ageing are in vision and audition and, to a lesser degree, olfaction and gustation. Findings for the somatosensory system (mechanoreception, warming and cooling thermoreception and pain) are less conclusive. Factors that contribute to individual differences in sensory ratings beyond chronological ageing include stimulus factors including stimulus type and body location, response measures and instructions, systemic disease that may affect the peripheral or central nervous system and environmental factors that may affect the skin integrity.
