AI Article Synopsis

  • Recent articles highlight the importance of quantitative sensory testing (QST) and pressure pain threshold (PPT) in evaluating neck/shoulder and low back pain, but lack standardized PPT reference values.
  • The review examines 97 studies to summarize current PPT data in chronic pain patients versus healthy volunteers while discussing measurement reliability and previous challenges in PPT evaluation.
  • The findings aim to create a benchmark for future research and enhance the clinical application of PPT assessments in general healthcare settings.

Article Abstract

In recent years, several published articles have shown that quantitative sensory testing (QST) and pressure pain threshold (PPT) are useful in the analysis of neck/shoulder and low back pain. A valid reference for normal PPT values might be helpful for the clinical diagnosis of abnormal tenderness or muscle pain. However, there have been no reliable references for PPT values of neck/shoulder and back pain because the data vary depending on the devices used, the measurement units, and the area examined. In this article, we review previously published PPT articles on neck/shoulder and low back pain, discuss the measurement properties of PPT, and summarize the current data on PPT values in patients with chronic pain and healthy volunteers. We also reveal previous issues related to PPT evaluation and discuss the future of PPT assessment for widespread use in general clinics. We outline QST and PPT measurements and what kinds of perceptions can be quantified with the PPT. Ninety-seven articles were selected in the present review, in which we focused on the normative values and abnormal values in volunteers/patients with neck/shoulder and low back pain. We conducted our search of articles using PubMed and Medline, a medical database. We used a combination of "Pressure pain threshold" and "Neck shoulder pain" or "Back pain" as search terms and searched articles from 1 January 2000 to 1 June 2022. From the data extracted, we revealed the PPT values in healthy control subjects and patients with neck/shoulder and low back pain. This database could serve as a benchmark for future research with pressure algometers for the wide use of PPT assessment in clinics.

Although previous studies have suggested an association between digital media use and health, detailed knowledge about how different types of digital media impact adolescent health is limited. This cross-sectional population-based study explored the relationship between time spent on various digital media and adolescents' self-rated general and mental health. The study included 3566 Swedish high school students aged 16-17 years.

Background And Aims: Multisite pain is a prevalent and significant issue among adolescents, often associated with adverse physical, psychological, and social outcomes. We aimed to (1) predict multisite pain incidence in the whole body and in the musculoskeletal sites in adolescents, and (2) explore the sex-specific predictors of multisite pain incidence using a novel machine learning (ML) approach (random forest, AdaBoost, and support vector classifier).

Methods: A 2-year longitudinal observational study (2013-2015) was conducted in a population-based sample of Finnish adolescents ( = 410, 57% girls, 12.

During the coronavirus disease 2019 (COVID-19) pandemic, the COVID-19 surveillance staff members experienced an increased risk for musculoskeletal disorders. Thus, it is necessary to further investigate the causal factors stemming from COVID-19 surveillance work, especially nucleic acid testing, and establish their relationship with work-related musculoskeletal disorders (WMSDs) by building upon the previous research. This study aimed to determine the prevalence of WMSDs and the major risks faced by the COVID-19 surveillance staff members.

Impact of chronic low back pain on implicit motor imagery assessed by a new laterality judgment task.

Université de Poitiers, Université François-Rabelais de Tours, CNRS, CeRCA, UMR 7295, F-86000 Poitiers, France; Université de Poitiers, Institut Pprime (UPR 3346), ISAE-ENSMA, CNRS, 86073 Poitiers, France.

It is clear that implicit motor imagery (IMI) is impaired by chronic pain in peripheral regions (hand, feet), but unclear in axial regions (neck, shoulder, back). Previous IMI tasks displayed small-amplitude movements of axial regions, which limits person-centered IMI processes mobilization. This study aimed to assess the impact of chronic low back pain (CLBP) on IMI processes with a new task displaying large-amplitude whole-body movements mobilizing the lumbar spine.

Introduction: Musculoskeletal disorders (MSDs) are rapidly rising in Saudi Arabia, reaching levels similar to those in the Western world. Hence, we aimed to assess the prevalence of neck, shoulder, and lower back pains (musculoskeletal pain, MSP) among students at King Khalid University in Abha, Saudi Arabia.

Methods: This cross-sectional study was conducted at King Khalid University in Abha, Saudi Arabia, from March 2023 to August 2023.
