WebNov 3, 2024 · They observed a reduction in C-fiber thresholds, while large-diameter myelinated low-threshold fibers actually demonstrated a desensitization and loss of receptive field area, supporting a model with reduced activation of tactile low-threshold afferents and increased responses of nociceptive afferents. WebMar 4, 2009 · Tactile thresholds. To quantitatively assess tactile thresholds and deficits of areas that may be affected by the lesions, von Frey filaments were used to examine the ventral forearms and dorsal calves bilaterally using the methods of constant stimuli. Minimum force (in newtons) required for subjects to consistently (greater than ∼75%) …

WebNov 1, 2024 · The objective of this experiment is to determine the tactile sensation threshold for each subject. Subsequent sub-threshold stimulation depends on the values determined in this experiment. Three perception thresholds are estimated for the rectangular pulse and two spatial distributions of the Gaussian noise stimulus. WebOct 28, 2015 · A stimulus intensity level of 90% of perception threshold (100%) has been shown to be effective in SR stimulation experiments, so each participant’s threshold was … WebAlthough tactile reactivity issues are commonly reported in children with autism spectrum disorder (ASD), the underlying mechanisms are poorly understood.
