Interaction analyses: Enhancing understanding of chronic low back pain.

Background: Chronic low back pain (CLBP) is complex. Statistical examination of influences of exposures (e.g.

How do people with chronic low back pain pick a pencil off the floor?

Background: Picking objects off the floor is provocative for people with chronic low back pain (CLBP). There are no clinically applicable methods evaluating movement strategies for this task. The relationship between strategy and multidimensional profiles is unknown.

Significant other interactions in people with chronic low back pain: Subgrouping and multidimensional profiles.

Back pain is complex. Social support and significant other interactions influence the pain experience. To statistically derive subgroups of people with chronic low back pain based upon their interactions with significant others, and profile subgroups across multidimensional variables.

Heritability of musculoskeletal pain and pain sensitivity phenotypes: 2 generations of the Raine Study.

There is a need to better understand biological factors that increase the risk of persistent musculoskeletal (MSK) pain and heightened pain sensitivity. Knowing the heritability (how genes account for differences in people's traits) can enhance the understanding of genetic vs environmental influences of pain and pain sensitivity. However, there are gaps in current knowledge, including the need for intergenerational studies to broaden our understanding of the genetic basis of pain.

Only one fifth of young Australian adults have beliefs about medical imaging for low back pain that align with current evidence: A cross-sectional study.

Background: Patients' perceptions/expectations may be a factor behind medical imaging referral rates. Few studies have investigated the beliefs that might drive expectations of medical imaging.

Objectives: This study examined whether beliefs of young Australian adults with and without impactful low back pain (LBP) concerning medical scans for LBP align with current evidence.

Do chronic low back pain subgroups derived from dynamic quantitative sensory testing exhibit differing multidimensional profiles?

Objectives: The relationship of pain sensitivity with pain and disability in low back pain (LBP) is complicated. It has been suggested increased understanding of dynamic quantitative sensory testing (QST) might be useful in increasing understanding of these relationships. This study aimed to create subgroups based on participant responses to dynamic QST, profile these subgroups based on multidimensional variables (including clinical measures of pain and disability, psychological and lifestyle variables and static QST), and investigate the association of subgroup membership with levels of pain intensity, LBP-related disability and disability risk at 12-month follow up.

STarT Back Tool risk stratification is associated with changes in movement profile and sensory discrimination in low back pain: A study of 290 patients.

Background: Investigation of movement and sensory profiles across STarT Back risk subgroups.

Methods: A chronic low back pain cohort (n = 290) were classified as low, medium or high risk using the STarT Back Tool, and completed a repeated spinal bending task and quantitative sensory testing. Pain summation, time taken and the number of protective behaviours with repeated bending were measured.

The predictive ability of the STarT Back Tool was limited in people with chronic low back pain: a prospective cohort study.

Questions: In people with chronic non-specific low back pain (LBP), what is the predictive and discriminative validity of the STarT Back Tool (SBT) for pain intensity, self-reported LBP-related disability, and global self-perceived change at 1-year follow-up? What is the profile of the SBT risk subgroups with respect to demographic variables, pain intensity, self-reported LBP-related disability, and psychological measures?

Design: Prospective cohort study.

Participants: A total of 290 adults with dominant axial LBP of≥3months' duration recruited from the general community, and private physiotherapy, psychology, and pain-management clinics in Western Australia.

Outcome Measures: The 1-year follow-up measures were pain intensity, LBP-related disability, and global self-perceived change.

Symmetry of trunk and femoro-pelvic movement responses to single leg loading tests in asymptomatic females.

Single leg loading tests are used clinically to examine balance and loading strategies in individuals with lower limb pain. Interpretation of these tests is through pain responses and comparisons with the asymptomatic leg. The purpose of this study was to examine normal differences in trunk and pelvic movement between legs during the single leg stand, single leg squat, hip hitch and hip drop tests, and to compare observational and quantitative assessments of trunk movement during the single leg squat test.

The effect of different standing and sitting postures on trunk muscle activity in a pain-free population.

Study Design: A normative, single-group study was conducted.

Objective: To determine whether there is a difference in electromyographic activation of specific lumbopelvic muscles with the adoption of common postures in a pain-free population.

Summary Of Background Data: Clinical observations indicate that adopting passive postures such as sway standing and slump sitting can exacerbate pain in individuals with low back pain.
