Objective
The objective of this study was to investigate the stresses and displacements of the sacroiliac joint as well as ligament strains under 3 conditions of manipulation of hip and knee flexion (MHKF).
Methods
A pelvis-femur finite element model was established. Three MHKFs were applied to the model, which involved 3 states of the hip joint. The 3 states were as follows – MHKF-F1: the hip was flexed to 155° and abducted to 35°; MHKF-F2: the hip was flexed to 155° and placed at neutral place; MHKF-F3: the hip was flexed to 155° and intorted to 35°. The stresses and displacements of the sacroiliac joint were calculated, and ligament strains were analyzed.
Results
Under 3 MHKFs, the maximum stresses on the pelvis produced by MHKF-F1, F2, and F3 were 154.1, 123.4, and 180.3 MPa, respectively. The maximum stresses on the sacroiliac joint produced by MHKF-F1, F2, and F3 were 3.9, 3.3, and 2.8 MPa, respectively. The sacroiliac joint displacements were all less than 0.252 mm under the 3 MHKFs. MHKF-F1 produced the largest displacement. Different levels of ligament strain were observed, and the greatest ligament strains were caused by MHKF-F3.
Conclusions
Three MHKFs produced different degrees of stress in the pelvis and sacroiliac joint. Three MHKFs could produce small sacroiliac joint displacements. However, they could produce different levels of ligament strains, and MHKF-F3 produced the greatest ligament strain.

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.

Objective
The purpose of this study was to assess the association of disability with cognitive patterns (pain catastrophizing and kinesiophobia) and psychological distress (anxiety and depressive symptoms) in individuals with chronic neck (CNP) and low back pain (CLBP).
Methods
This cross-sectional study included 150 individuals with CNP (n = 75) and CLBP (n = 75) who answered a personal assessment form, the Neck Disability Index, the Oswestry Disability Index, the Pain Catastrophizing Scale, the Tampa Scale of Kinesiophobia, the Beck Anxiety Inventory, the Beck Depression Inventory-II, and the visual analog scale (pain intensity). A multiple linear regression analysis was used to assess whether the independent variables were predictors of disability (P < .05).
Results
In individuals with CNP, pain catastrophizing (β = 0.5), kinesiophobia (β = 0.2), and anxiety symptoms (β = 0.3) served as predictors of disability (R² = 0.79; Adjusted R² = 0.78; F (3.71) = 90.6; P < .001). In individuals with CLBP, pain catastrophizing (β = 0.4) and pain intensity (β = 0.4) were predictors of disability (R² = 0.51; Adjusted R² = 0.50; F (2.72) = 34.4; P < .001).
Conclusion
Disability related to CNP and CLBP had different predictors, except for pain catastrophizing, which was associated with both. These findings suggest that cognitive patterns (ie, pain catastrophizing and kinesiophobia) and psychological distress (ie, anxiety symptoms) should be considered during CNP and CLBP rehabilitation and further investigated by health professionals.

Objective
The aim of this study was to determine the immediate effects of spinal manipulation (SM) on motor performance of eye and head movement tasks in symptomatic and asymptomatic participants with chronic neck pain.
Methods
This observational study utilized a between and within group analyses to assess the effects of cervical SM in symptomatic (n = 20) and asymptomatic (n = 20) groups. Participants performed goal-directed eye and head movement tasks before and after cervical SM, to identify changes in eye and head motor performance. Eye and head movement time (MT) was analyzed as a primary outcome. Secondary outcomes included eye and head peak velocity and time to peak velocity.
Results
During the eye movement task, there was no significant effect of SM on MT. During the head movement task, there was a significant SM by group interaction for MT and significant effect of SM on MT during the amplitude and width conditions within the symptomatic group indicating that head MTs were reduced in both analyses.
Conclusion
There was no effect of SM on eye MTs. However, the significant effect of SM on head MT provides evidence for changes in head control following SM. Given the SM targeted the cervical spine, the changes in MT were only present for head movements, we propose the observed changes may result from both neuromuscular and sensorimotor adaptations following SM.

This study aimed to investigate the changes in the thickness of the diaphragm muscle during 4 different postures in individuals with and without chronic low back pain (LBP) using transcostal rehabilitative ultrasound imaging.
Method
This cross-sectional study was conducted on 56 participants, including 28 patients with nonspecific chronic LBP (14 males and 14 females) and 28 individuals without LBP (14 males and 14 females), aged 20 to 45 years. Diaphragm thickness and diaphragm thickness fraction (DTF) of the right hemidiaphragm were assessed via B-mode ultrasound in supine, sitting, standing, and straight leg raised (SLR) positions in different respiratory phases, including inspiration, expiration, and deep inspiration.
Results
In each group, diaphragm thickness was found to be different among supine, SLR, sitting, and standing positions in all respiratory phases (P < .001). The difference in diaphragm thickness between the LBP and non-LBP groups was more obvious in the SLR position (P = .035). Moreover, groups differed significantly in DTF in SLR, sitting, and standing positions (P < .001).
Conclusion
Increased load on the lumbar region caused by elevating the lower limb and posing more upright postures resulted in a thicker diaphragm. Based on the results, the SLR position reflected the differences in diaphragm thickness between the study groups more efficiently than other positions, which might be attributed to impaired load transfer through the lumbopelvic region in individuals with back pain. Furthermore, DTF seemed to be more sensitive compared to the thickness measurement for the identification of differences between patients with LBP and healthy individuals.

Objective
The purpose of this study was to investigate the relationship between lower extremity alignment, postural control, and physical performance in patients with chronic low back pain.
Methods
Sixty patients with chronic low back pain, aged between 18 to 65 years, were included in the study. Alignment of the lower extremities of patients was evaluated as mechanical distal femoral angle, medial proximal tibial angle, mechanical tibiofemoral angle, joint line convergence angle, anatomical tibiofibular angle, anatomical-mechanical angle, anatomical lateral distal femoral angle, and Q angle. Other variables included the numeric pain scale, static balance, one-leg stand, dynamic balance, the star excursion balance test, and the physical performance evaluation test battery.
Results
A moderately strong correlation was found between dominant lower extremity anatomical tibiofibular angle and anteromedial, medial, and posterolateral dynamic balance measurements of the patients, and between Q angles and dominant lower extremity anteromedial measurements. A moderately strong correlation was found between the patients’ anatomical-mechanical angle and the sock test, roll-up, and fingertip-to-floor test. A moderately strong correlation was found between the Q angle and the sock test, pick-up, and fingertip-to-floor test (P < .05).
Conclusions
Altered lower extremity alignment of the patients in this study was found to be related to their postural balance and physical performance.

Objective
The purpose of this study was to investigate the relationship between symptoms across body systems and health outcomes in individuals with chronic whiplash-associated disorders (WADs).
Methods
A cross-sectional study was conducted at a multidisciplinary chronic pain center in Calgary, Canada, between October 2019 and December 2021. Participants with a history of WAD completed questionnaires assessing pre-existing symptoms across bodily systems and related health outcomes. Mediation analyses evaluated the associations between symptom profiles and health outcomes, as well the role of pain cognitions.
Results
Of 305 participants in the registry database, 238 were eligible. The majority reported symptoms from 2 or more body systems, especially neurological, gastrointestinal, and psychological symptoms. Participants demonstrated moderate-to-severe pain and disability, with low physical health-related quality of life. While multiple symptoms correlated with worse health outcomes, mediation analyses revealed pain cognitions primarily influenced these associations, except for eye-related symptoms, which directly correlated with pain and disability.
Conclusion
The study highlights that chronic WAD is characterized by a complex symptom profile across various bodily systems. Although a broader symptom profile is linked to poorer health outcomes, the effects are often mediated by pain cognitions. Notably, prior health conditions did not adversely impact outcomes, suggesting a need for targeted interventions focusing on cognitive aspects in patients with chronic WAD.

Objective
The purpose of this study was to translate, cross-culturally adapt, and validate the Measure of Intermittent and Constant Osteoarthritis Pain (ICOAP) hip into Brazilian Portuguese in individuals with hip osteoarthritis (OA).
Methods
One hundred thirty individuals with hip OA participated in the study, 30 in stage 1, transcultural translation and adaptation, and 100 in stage 2, structural validity. Convergent validity was assessed using the Spearman correlation by applying the Numeric Rating Pain Scale (NRPS), the Hip Dysfunction and Osteoarthritis Outcome Score (HOOS), and the Short Form 36 Health Survey (SF-36). The internal structure was evaluated by exploratory and confirmatory factor analysis with the fit indices chi-square/degrees of freedom (DF), Root Mean Square Error of Approximation (RMSEA), Standardized Root Mean Square Residual (SRMR), Comparative Fit Index (CFI), Tucker Lewis Index (TLI), and floor and ceiling effects. Of the 100 participants, a subsample of 50 was used to assess test-retest reliability using the intra-class correlation coefficient (ICC), standard error of measurement (SEM), minimum detectable change (MDC), and internal consistency by Cronbach’s alpha (α).
Results
the ICOAP hip showed adequate values for all fit indices: chi-square/GL = 1.05; CFI = 1.00; TLI = 1.00; RMSEA (90% CI) = 0.024 (0.000 to 0.073); SRMR = 0.031. The reliability analysis presented excellent test-retest reliability and internal consistency values >0.90. Regarding convergent validity, correlations >0.50 were found between the ICOAP hip constant pain and HOOS, SF-36, and the NRPS.
Conclusion
The ICOAP hip in Brazilian Portuguese presents acceptable psychometric properties, supporting its use in individuals with hip OA.
