Pain Sensitivity Assessment in Clinical Conditions

Pain sensitivity assessment encompasses a range of psychophysical and neurophysiological techniques designed to characterise individual responses to nociceptive stimuli in both health and disease. In clinical settings, these assessments serve to identify aberrant sensory processing, stratify patients according to underlying mechanisms, monitor treatment response and predict the risk of chronic pain development. Common approaches include quantitative sensory testing to determine thermal and mechanical detection and pain thresholds, measures of temporal summation and conditioned pain modulation to probe central facilitatory and inhibitory pathways, and self-report scales that integrate intensity, affective and functional dimensions. Recent advances have focused on refining protocols for portability and cost-effectiveness, integrating wearable technology for ecological monitoring, and combining sensory phenotyping with genetic and biomarker profiling. Collectively, these tools are reshaping personalised pain management by guiding mechanism-based interventions, informing early-intervention strategies and facilitating cross-disciplinary research into nociplastic pain and neuropathic syndromes.

Pain Sensitivity Assessment in Clinical Conditions publication trend

The graph below shows the total number of articles in pain sensitivity assessment in clinical conditions across all publications each year (not limited to Nature Index journals).

Technical terms

Nociplastic pain: Pain arising from altered nociception despite no clear evidence of tissue damage or somatosensory lesion.

Quantitative sensory testing (QST): A set of standardised psychophysical methods to measure detection and pain thresholds for thermal and mechanical stimuli.

Temporal summation of pain: Progressive increase in pain perception during repetitive noxious stimulation, reflecting central facilitation.

Central sensitisation: Amplification of nociceptive signalling within the central nervous system leading to hypersensitivity.

Pressure pain threshold: The minimum force applied to evoke a pain sensation, used to assess mechanical sensitivity.
