Objective: The purpose of this study was to assess the influence of prior imaging review on recommendations for additional diagnostic testing in an academic chiropractic radiology practice. A secondary aim was to explore the influence of prior imaging review on radiographic interpretation.

Methods: We retrospectively reviewed radiology reports generated from July 18, 2022, to July 18, 2023, from the Palmer College of Chiropractic main campus (Davenport, Iowa) clinic system. Imaging interpretation included an automated search for prior images in an internal picture archival and communication system (PACS). Images from regional health system databases were available and sought by radiologists when (1) unclear radiologic findings had potential clinical implications or (2) prior imaging could clarify potential problems detected in a clinical history. Data were abstracted to a secure adaptive electronic questionnaire and analyzed descriptively.

Results: We reviewed 1712 radiographic and 165 musculoskeletal diagnostic ultrasound reports for 1552 unique individuals (811 [52.3%] females and 741 [47.7%] males) with a mean age of 42.1 years (range, 2-93 years). Prior imaging was described in 417 (22.2%) reports; 246 (58.9%) indicated images from internal PACS, 192 (46.0%) indicated images from external PACS, and 21 noted both internal and external PACS. Prior imaging findings were credited with answering a clinical question in 98 (23.5%), and a radiographic question in 228 (54.7%) of 417 reports. The process negated the need for follow-up diagnostic testing recommendations in 119 (28.5%) instances, leading to additional imaging recommendations in 19 (4.6%).

Conclusion: Data obtained in this study suggest that comparing current and previous imaging may help reduce unnecessary additional imaging or follow-up diagnostic testing recommendations. Prior imaging review may also facilitate diagnostic confidence and interpretation clarity.

Objective: This study aimed to describe the frequency, and the strength of the association, between bullying and pain in Australian schoolchildren.

Methods: We used nationally representative data from the 2014 Australian Child Wellbeing Project, comprised students aged 8 to 14 years from 180 schools. Weighted, multiple logistic regression models (adjusting for sex and school year) were constructed to quantify the association between weekly or more frequent bullying and weekly or more frequent pain. Estimates of association for the relationship between bullying and pain were reported as odds ratios (OR).

Results: The sample was comprised of 5,440 schoolchildren (51.9% female). The prevalence rates of weekly or more frequent pain in the sample were headache (32.3%), backache (23.5%), and stomach ache (21.7%). Between 4.3% and 7.9% of participants reported weekly or more frequent bullying. In schoolchildren reporting bullying, the prevalence of pain ranged from 43.1% to 64.3%. Logistic regression modeling showed moderate-to-strong positive associations (OR, 2.1 [95% CI, 1.8-2.5] to 4.5 [95% CI, 3.7-5.6]) between the experiences of schoolchildren reporting any bullying type and any pain type.

Conclusion: Australian schoolchildren who reported bullying were more likely to experience headache, stomach ache, and backache. The moderate-to-strong positive association is consistent with previous international studies that have examined the association between bullying and pain in young people. These findings have significant implications for clinicians who provide care for young people, as well as educators and healthcare policymakers, highlighting the important role of coexisting psychosocial factors in the management of adolescents who report pain.

Objective: The pressure pain threshold is commonly employed to assess pain in various conditions. Despite its widespread use, the measurement of pressure pain thresholds is not consistently described across studies. Therefore, this review aimed to systematically examine the evidence regarding the assessment of pressure pain thresholds in patients with low back pain, including the protocols and body sites employed.

Methods: Six databases were systematically screened from their earliest records to May 2023 to identify studies utilizing pressure pain thresholds. Eligibility screening was conducted for the identified studies, and the included studies underwent appraisal using the appropriate tool corresponding to their study design.

Results: Upon categorizing based on the type of pain, we included 5 studies involving acute low back pain and 43 studies with chronic pain. The meta-analysis was conducted to compare subjects with and without pain, revealing no significant difference for the paraspinal region (SMD = -4.19, 95%CI = -11.7 to 3.32, z = -1.09, p = .27), piriformis (SMD = -1.24, 95%CI = -4.25 to 1.76, z = -0.81, p = .42) and quadratus lumborum musculature (SMD = -0.37, 95%CI = -1.35 to 0.60, z = -0.75, p = .45).

Conclusion: The paraspinal and gluteal musculature are the most frequently evaluated. Concerning the protocols for assessment, no consensus was identified. However, studies that assessed chronic low back pain typically adhered to a similar approach regarding the number of measures and a constant increase in pressure.

Objective: The purpose of this study was to assess the effects of different spinal manipulation (SM) techniques and target segments on a specific dermatome and myotome, when compared with a remote spinal cord segment that served as a control location.

Methods: Twenty-nine healthy volunteers were randomized to receive instrumental (Activator IV, Activator Methods International Ltd) or manual SM at the C6, C1, and T4 vertebral segments in 3 independent sessions. Pressure pain thresholds (PPTs) and muscle strength were examined at the C6 (test) and L4 (control) dermatomes and myotomes, at baseline and after intervention. Linear mixed-effects models were used to analyze changes over time and interindividual variability.

Results: Pressure pain thresholds significantly increased at both proximal and distal C6 dermatome locations (P < .05), irrespective of the technique and segment of application (P > .2). No significant changes were observed at the L4 dermatome. Muscle strength remained unchanged throughout the study. Multilevel modeling revealed significant associations between increased PPTs along the C6 dermatome (P < .001), whereas the combination of technique and target segment predicted PPT increases at the proximal C6 dermatome.

Conclusion: These findings support regional, rather than segmental mechanisms underlying the sensory effects of SM. Specifically, significant increases in PPTs along the C6 dermatome suggest localized effects on pain sensitivity, which may depend on the target spinal region. Further investigation is needed to better understand these regional changes of SM and their potential clinical implications.

Objective: The purpose of this study was to compare the effects of foot positioning on muscle activities of the peroneus longus (PL), medial gastrocnemius (MG), and tibialis anterior (TA)/PL ratio in individuals with chronic ankle instabilities (CAI) during wobble board training.

Methods: Thirty individuals with CAI were included, and statistical significance of PL and MG muscle activities was determined using 1-way repeated measures analysis of variance alongside TA/PL activity ratio at the university research laboratory. The participants performed the wobble board training in 3 different foot positions: medial from the centerline of the wobble board (WBT-M), middle from the centerline of the wobble board, and lateral from the centerline of the wobble board (WBT-L). Peroneus longus, MG, and TA muscle activities were measured using surface electromyography.

Results: Peroneus longus activity was significantly higher in the WBT-L position than in the other 2 positions, and it was significantly higher in the middle from the centerline of the wobble board than in the WBT-M position. Medial gastrocnemius activity was significantly greater in the WBT-L position than in the other 2 positions. Tibialis anterior/PL ratio was higher in the WBT-M position than in the other 2 positions.

Conclusion: The findings of this study showed that WBT-L increased PL muscle activity by >70% of the maximal voluntary isometric contraction without increasing TA/PL ratio in individuals with CAI.

Objective: The objectives of the study were to (1) determine the association between kinesiophobia and lumbar joint position sense (JPS) in individuals with chronic low back pain (CLBP); (2) examine the relationship between kinesiophobia and postural stability in individuals with CLBP; and (3) investigate whether pain intensity mediates the relationship between kinesiophobia, lumbar JPS, and postural stability in individuals with CLBP.

Methods: In this cross-sectional study, a total of 83 individuals diagnosed with CLBP were included. The level of fear of movement was assessed using the Tampa Scale for Kinesiophobia (TSK). Lumbar JPS was measured using the active target repositioning technique, which involved evaluating JPS in 3 directions: lumbar flexion, side-bending to the left, and side-bending to the right. The repositioning accuracy of the lumbar joint was quantified in degrees using a dual digital inclinometer. Postural stability was assessed using a stabilometric force platform, which measured anterior to posterior (A-P) sway, medial to lateral (M-L) sway, and the ellipse area in mm².

Results: The findings of this study revealed a statistically significant and moderate positive correlation between kinesiophobia and lumbar JPS in various directions, including flexion (r = 0.51, P < .001), side-bending to the left (r = 0.37, P = .001), and side-bending to the right (r = 0.34, P = .002). Similarly, a significant positive association was observed between kinesiophobia and postural stability, as indicated by the correlation coefficients: A-P sway (r = .47, P < .001), M-L sway (r = 0.58, P < .001), and ellipse area (r = 0.51, P < .001). Furthermore, the analysis revealed that pain significantly mediated the relationship between kinesiophobia and both lumbar JPS (P < .05) and postural stability (P < .05). These findings were demonstrated through mediation analysis.

Conclusions: This study identified a significant association between kinesiophobia, lumbar JPS, and postural stability. Additionally, we observed the presence of pain as a potential mediator in this relationship. However, it is important to note that our cross-sectional study design precludes establishing causality or determining the direct mediation effect of pain on adverse outcomes.

Objectives: The purpose of this study was to examine long-term brain and behavioral changes in patients with fibromyalgia (FM) compared to healthy individuals.

Methods: Data from 33 female volunteers with FM and 33 healthy controls women paired by age and school degree were used to analyze the cortical thickness from high-resolution T1-weighted magnetic resonance imaging (MRI) obtained through a 3T-MRI scanner. Additionally, the Toronto Alexithymia Scale, the Positive and Negative Affect Scale, the emotion regulation questionnaire (ERQ), and the Hamilton Depression and Anxiety rating scales were used to evaluate the behavioral changes.

Results: The findings indicate significant cortical structure differences in the right cerebral hemisphere between groups in the insular anterior cortex precentral and postcentral gyrus (P < .001). The FM group scored higher for alexithymia (P < .01), negative affect (P < .01), anxiety (P < .01), and depression (P < .01) symptoms, on the other hand, scored lower for positive affect (P < .01). No differences were found on the left cerebral hemisphere. Furthermore, there was a negative correlation between the right insular anterior cortex and Toronto Alexithymia Scale (P < .001).

Conclusion: This study showed long-term brain and behavioral changes in patients with FM, suggesting notable neurophysiological alterations associated with this chronic pain condition. It provides new insights into how FM may affect brain health and potential biomarkers for the condition.

Objectives: The purpose of this study was to measure the association between the level of physical activity and sedentary conditions with anthropometric measurements of children and adolescents.

Methods: This cross-sectional descriptive study consisted of a convenience sample of 400 children and adolescents from public schools in Itapevi-SP, Brazil. The Physical Activity Checklist Interview or LAF "Lista de Atividades Físicas" in a Brazilian version, was administered in a face-to-face interview on a school day and allowed assessment of sedentary behavior and physical activity on the previous day. Anthropometric measurements included body weight, sex, age, and lower limb posture. The participants were photographed in the frontal and sagittal planes, and the photos were analyzed using postural assessment software (PAS/SAPO). Pearson's tests were applied to analyze correlations.

Results: Children and adolescents show a greater tendency toward valgus knees with increasing body mass (r = ‒0.33). On average, girls have a larger Q angle. Ankles are less likely to become valgus with increasing age and mass (r = ‒0.18 and ‒0.23, respectively). The horizontal alignment of the pelvis is mostly in anteversion with a significant increase with age (r = 0.27) and a slight increase with mass (r = 0.15). The knee and ankle tend to be less hyperextended and more dorsiflexed from the age of 10, with no correlation with the other variables. It was not possible to observe a clear relationship between the time spent in physical activity and sedentary behavior and the postural angles mentioned above.

Conclusion: Although correlations were found between age, sex and body mass, and postural angles, notably pelvis alignment, Q angle, knee, ankle, sex, and body weight, there was no correlation between the time spent in physical activity, sedentary behavior, and lower limb posture.

Objectives: The aim of this study was to investigate the 3-dimensional movement kinematics of pelvic and lower limb joints in CLBP subjects, compared to healthy individuals, utilizing a functional data analysis (FDA) approach.

Methods: In this study, a 7-camera Qualisys motion capture system was employed to record the kinematics of the pelvic, hip, knee, and ankle joints in 20 patients with low back pain (LBP) and 20 control subjects on both sides during the sit-to-stand motion. An FDA statistical approach was utilized to compare the data collected over time between the 2 groups. The STS task was divided into two distinct phases: the prelift off phase (pre-Lo) and the postlift off phase (post-Lo).

Results: During the "pre-Lo phase" of the STS motion, our statistical analysis revealed that the only significant difference between the two groups was a decreased medial rotation (P = .00) in the hip joint position of LBP patients on their dominant side, in comparison to healthy subjects. As for the "post-Lo phase," the LBP group exhibited a more anterior pelvic tilt position (P = .00) and increased pelvic counterclockwise rotation (P = .03) in the sagittal and transverse planes when compared to the control group. Regarding hip joints, the LBP group demonstrated a more flexed position (indicative of reduced extension) on both the dominant (P = .00) and nondominant (P = .00) sides, coupled with diminished abduction (P = .04) and internal rotation (P = .03) of the hip on the dominant side. In relation to the knee and ankle joints, the results indicated a more adducted knee position (P = .00) and decreased ankle joint flexion (P = .02) on the dominant side in CLBP subjects when compared to the healthy group during the STS motion.

Conclusion: Our findings indicate that patients with CLBP exhibited distinct kinematic patterns in the pelvic and lower limb joints during the STS motion. These kinematic alterations primarily manifest in the joints of the dominant limb, with most of the differences observed during the second phase (postlift off phase) of the motion. It appears that these changes in pelvic and lower limb joint kinematics should be taken into account when planning future rehabilitation programs for CLBP patients engaged in this task.

Objectives: This study aimed to review and describe the scientific literature on approaches used for the management of nonspecific low back pain (NSLBP) in Africa.

Methods: For this scoping review, a comprehensive literature search was conducted using the EBSCO host platform to search the following databases: CINAHL with full text, MEDLINE with Full Text, PubMed, Springer Nature Journals, Directory of Open Access Journals, Science Direct, Gale OneFile: Health & Med, Google Scholar, and Gale Health & wellness. Articles published between January 1990 and March 2021 were included. We used Boolean operators and Medical Subject Headings (MeSH) with the JBI Scoping Review Methodology framework. Results were reported using the PRISMA extension for scoping reviews (PRISMA-ScR).

Results: The search yielded 425 articles; 22 articles met the criteria for inclusion. Various disciplines were consulted for the management of NSLBP including primary care medical physicians, physiotherapists, chiropractors, orthopedic surgeons, pastors, and traditional healers. Management of NSLBP involves pain medication as the most common form of treatment. The review suggests that understanding cultural beliefs and biopsychosocial factors is important for managing NSLBP in Africa. Although attempts are being made in some countries to encourage the adoption of international and locally developed evidence-based guidelines, very few practitioners are providing such care.

Conclusion: The peer-reviewed published literature on the treatment of NSLBP in Africa is limited and with few exceptions of low quality. In order to provide a higher level of care for people disabled with NSLBP in Africa considerable further research and greater collaboration and utilization of limited clinical resources are needed.
