The Role of Sensory Processing Sensitivity in Pediatric Chronic Pain

May 17, 2022 updated by: Helen Koechlin, University Hospital, Basel, Switzerland

Towards a Deeper Understanding of Chronic Pediatric Pain: Exploring the Role of Sensory Processing Sensitivity

The aim of this project is to increase scientific understanding of whether the trait of SPS can help explain increased pain sensitivity and hence vulnerability for chronic pain. Additionally, it will be tested whether participants with high SPS report differences in pain intensity in response to positive, negative, or neutral mood induction compared to individuals with lower SPS.

Detailed Description

Background: Pain is defined as an unpleasant sensory and emotional experience and in its chronic form, pain is highly prevalent, up to 25% of children and adolescents are affected by it. The exact etiology of many forms of chronic pain remains unknown. One mechanism that has been proposed to underlie increased pain sensitivity is central sensitization, i.e., increased efficacy of the nervous system in transmitting pain signals, which manifests itself as a lower pain threshold. A lower pain threshold in turn has been recognized as a risk factor for the development of chronic pain. Being more sensitive to pain is one feature commonly shared by those with high sensory processing sensitivity (SPS), who are thought to react more strongly to both positive and negative environmental influences. The relationship between this increased sensitivity and pain tolerance has not been studied to date, but could contribute to our understanding of why some children and adolescents are more vulnerable to developing chronic pain than others.

Objectives and Aims: The aim of this project is to increase scientific understanding of whether the trait of SPS can help explain increased pain sensitivity and hence vulnerability for chronic pain. Additionally, it will be tested whether participants with high SPS report differences in pain intensity in response to positive, negative, or neutral mood induction compared to individuals with lower SPS.

Methods: To examine differences in pain perception of an experimentally induced pain stimulus between people with varying levels of SPS and whether pain perception can modulated by positive, negative, or neutral mood induction, I will apply a heat pain paradigm in a sample of healthy adolescents. Participants will be randomized to either neutral, positive or negative mood induction and I will test whether their pain sensitivity differs as a function of their scores on a high sensitivity scale and with regard to mood induction.

Expected Results: We expect highly sensitive adolescents to have a lower pain threshold and tolerance and to react more strongly to positive (with decreased pain ratings) and negative (with increased pain ratings) mood induction compared to those with lower scores on the sensitivity scale.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Positive Mood
This group will be exposed to a positive mood induction prior to heat pain.
Behavioral: Heat Pain Paradigm
A standardized heat pain paradigm will be applied. Pain threshold will be determined with the self-controlled search method starting at 32°C, with a mouse-click-induced increase of 0.1°C per click. Pain tolerance is defined as the time in seconds elapsed from the onset of the pain stimulus to a participant's withdrawal from the stimulus. Participants will be instructed to continue with the task for as long as they can and to press a button if it becomes too uncomfortable or painful. Temperature will then return to baseline. To avoid physical injury, the measurement will stop automatically at a maximum temperature of 50°C.
Negative Mood
This group will be exposed to a negative mood induction prior to heat pain.
Behavioral: Heat Pain Paradigm
A standardized heat pain paradigm will be applied. Pain threshold will be determined with the self-controlled search method starting at 32°C, with a mouse-click-induced increase of 0.1°C per click. Pain tolerance is defined as the time in seconds elapsed from the onset of the pain stimulus to a participant's withdrawal from the stimulus. Participants will be instructed to continue with the task for as long as they can and to press a button if it becomes too uncomfortable or painful. Temperature will then return to baseline. To avoid physical injury, the measurement will stop automatically at a maximum temperature of 50°C.
Neutral Mood
This group will be exposed to a neutral mood induction prior to heat pain.
Behavioral: Heat Pain Paradigm
A standardized heat pain paradigm will be applied. Pain threshold will be determined with the self-controlled search method starting at 32°C, with a mouse-click-induced increase of 0.1°C per click. Pain tolerance is defined as the time in seconds elapsed from the onset of the pain stimulus to a participant's withdrawal from the stimulus.
