The symptom profile of people with whiplash-associated disorder - A mixed-method systematic review.

Background: Several studies have shown that people with whiplash-associated disorder (WAD) may experience diverse symptoms, and social, activity and participation limitations. However, the symptom profile of WAD is still unclear. Therefore, this systematic review aimed to identify the symptoms, impairments, activity limitations, and participation restrictions of people with WAD to construct a symptom profile.

Sensorimotor tests in patients with neck pain and its associated disorders: a systematic review and meta-analysis.

This systematic review aimed to synthesize the current evidence regarding neck sensorimotor testing in individuals with neck pain, assess the differences between neck pain groups and healthy controls, and recognize factors that might affect test results. We performed the data search using PubMed, Embase, PsycINFO, CINAHL, and Scopus databases. We used a two-step screening process to identify studies.

Association of accelerometer-measured physical activity, back static muscular endurance and abdominal obesity with radicular pain and non-specific low back pain.

Low back pain (LBP) is the leading cause of disability worldwide and often associated with lifestyle factors. However, studies further examining the role of these lifestyle factors in non-specific low back pain in comparison with radicular pain are sparse. The aim of this cross sectional study was to investigate how diverse lifestyle factors are associated with LBP.

Lower thoracic spine extension mobility is associated with higher intensity of thoracic spine pain.

Objectives: To evaluate the association of thoracic spine (TS) posture and mobility with TS pain.

Methods: Participants with TS pain reported maximum, average, and night pain in TS area, and pain summary score was calculated. Upright and sitting TS postures were evaluated by inspection.

Intra- and inter-rater reliability of thoracic spine mobility and posture assessments in subjects with thoracic spine pain.

Background: The thoracic spine (TS) has been neglected in the study of the spine despite its essential role in the stability and posture of the entire spinal complex. Therefore, there is an inevitable need to investigate the reproducibility of different thoracic spinal posture measures used in subjects with TS pain.

Methods: Thirty-two subjects (16 females and 16 males, mean age 39 years) were evaluated by two physiotherapists on the same day to gauge inter-rater reliability and on two consecutive days to gauge intra-rater reliability.

Association between adolescent sport activities and lumbar disk degeneration among young adults.

The relationship between different sport activities and lumbar intervertebral disk degeneration (DD) is largely unknown. We evaluated whether adolescent participation in different sports is associated with lumbar DD in a population-based birth cohort of young adults. A total of 558 young adults (325 females and 233 males) underwent magnetic resonance imaging (MRI, 1.

Body mass index is associated with lumbar disc degeneration in young Finnish males: subsample of Northern Finland birth cohort study 1986.

Background: The role of environmental factors in lumbar intervertebral disc degeneration (DD) in young adults is largely unknown. Therefore, we investigated whether body mass index (BMI), smoking, and physical activity are associated with lumbar DD among young adults.

Methods: The Oulu Back Study (OBS) is a subpopulation of the 1986 Northern Finland Birth Cohort (NFBC 1986) and it originally included 2,969 children.

Association of abdominal obesity with lumbar disc degeneration--a magnetic resonance imaging study.

Purpose: To evaluate whether midsagittal (abdominal) obesity in magnetic resonance imaging (MRI), waist circumference (WC) and body fat percentage are associated with lumbar disc degeneration in early adulthood.

Methods: We obtained the lumbar MRI (1.5-T scanner) of 325 females and 233 males at a mean age of 21 years.

Influence of physical activity on vertebral strength during late adolescence.

Background Context: Reduced vertebral strength is a clear risk factor for vertebral fractures. Men and women with vertebral fractures often have reduced vertebral size and bone mineral density (BMD). Vertebral strength is controlled by both genetic and developmental factors.

Association of modic changes, Schmorl's nodes, spondylolytic defects, high-intensity zone lesions, disc herniations, and radial tears with low back symptom severity among young Finnish adults.

Study Design: A cross-sectional magnetic resonance imaging (MRI) study.

Objective: We investigated the association among Modic changes, Schmorl's nodes, spondylolytic defects, high-intensity zone lesions, radial tears, herniations, and low back symptom severity.

Summary Of Background Data: Disc degeneration is associated with low back pain in early adulthood, but the associations between other MRI findings and low back pain are not well known.

Genetic susceptibility of intervertebral disc degeneration among young Finnish adults.

Background: Disc degeneration (DD) is a common condition that progresses with aging. Although the events leading to DD are not well understood, a significant genetic influence has been found. This study was undertaken to assess the association between relevant candidate gene polymorphisms and moderate DD in a well-defined and characterized cohort of young adults.

Does lumbar disc degeneration on magnetic resonance imaging associate with low back symptom severity in young Finnish adults?

Study Design: A cross-sectional magnetic resonance imaging study with questionnaires on low back pain (LBP) and functional limitations.

Objective: To investigate the association between lumbar intervertebral disc degeneration (DD) and low back symptom severity among young Finnish adults.

Summary Of Background Data: Both LBP and lumbar DD are common already in adolescence, but very little is known of their association in young adults.

Assessment of association between low back pain and paraspinal muscle atrophy using opposed-phase magnetic resonance imaging: a population-based study among young adults.

Study Design: A cross-sectional imaging study of young adults.

Objective: To evaluate whether severity of low back symptoms predicts atrophy in the paraspinal muscles of young adults.

Summary Of Background Data: Although an increased fat content of the lumbar muscles has been observed among adults with chronic LBP, there is limited knowledge of this association in younger populations.

Prevalence of degenerative imaging findings in lumbar magnetic resonance imaging among young adults.

Study Design: A cross-sectional imaging study of young adults.

Objective: To investigate the prevalence of disc degeneration (DD) and displacement, anular tears, and Modic changes in lumbar magnetic resonance imaging (MRI) among young adults.

Summary Of Background Data: Although low back pain in young adulthood is common, the prevalence of spinal MRI findings at this age remains virtually unknown.
