Aim: There is a need to evaluate the tissue deformation index of lateral abdominal muscles using M-mode ultrasound in a cohort of healthy subjects to establish a convenient reference point for clinical reasoning in patients. The aim of the study was to assess differences in the tissue deformation index between individual lateral abdominal muscles regardless of body side, compare these differences in the tissue deformation index on the right and left sides of the body, and evaluate side-to-side differences in the tissue deformation index within individual lateral abdominal muscles.
Material And Methods: In a group of 126 healthy volunteers (59 females), the postural response of lateral abdominal muscles to external perturbation in the form of rapid arm abduction with load was recorded on both sides of the body, and the tissue deformation index was calculated.
The spread of pain across body locations remains poorly understood but may provide important insights into the encoding of sensory features of noxious stimuli by populations of neurons. In this psychophysical experiment, we hypothesized that more intense noxious stimuli would lead to spread of pain, but more intense light stimuli would not produce perceptual radiation. Fifty healthy volunteers (27 females, 23 males, ages 14-44 years) participated in this study wherein noxious stimuli (43, 45, 47, and 49°C) were applied to glabrous (hand) and hairy skin (forearm) skin with 5-second and 10-second durations.

However, there is insufficient data for many applications, as data collection is often challenging and time-consuming. The same applies to automated pain recognition, where algorithms aim to learn associations between a level of pain and behavioural or physiological responses.

- Offset analgesia (OA) reflects how the body modulates pain but its mechanisms are still unclear, involving both central and peripheral factors, particularly A-delta fibers.
- This study tested the effects of blocking A-fiber conduction using a compression method on healthy participants to see how it influenced OA responses to heat stimuli.
- Results showed that while OA was present before, during, and after the blockade, no significant effect of A-fiber blockade was detected, suggesting that central mechanisms might play a more critical role in OA than peripheral A-fibers.
