The association of limited or painful spinal range of motion with lumbar disc degeneration: the back complaints in older adults (BACE) study.

We currently lack clear definitions for structural and symptomatic spinal osteoarthritis (OA). To define spinal OA and create diagnostic criteria for this condition, it is necessary to determine the relationship between clinical signs and symptoms of back pain and radiographic features of OA. Notably, recent studies suggest a defining sign of spinal OA could be a limited or painful spinal range of motion (ROM). Therefore, our objective was to assess the association between restricted or painful active spinal ROM, and multilevel structural features of lumbar disc degeneration (LDD) (i.e., disc space narrowing, osteophytes) on radiographs. We used the baseline data from the'Back Complaints in Older Adults' (BACE) study. The association between a limited or painful active spinal ROM, and multilevel disc space narrowing or osteophytes was assessed using multivariable logistic regression adjusted for age, mean pain intensity in the previous week, sex, BMI, and the Fear Avoidance Belief Questionnaire score. Primary analyses were performed on imputed datasets. We included 675 patients with a mean age of 66.52years (SD 7.69). Limited latero-flexion (fingertip that at best reached halfway up the upper leg) was associated with increased odds of having multilevel osteophytes (OR 1.85; 95% CI: 1.13 to 3.01). However, a limited or painful ROM in other directions (i.e., rotation, ante-flexion) was not associated with multilevel osteophytes, and a limited or painful active ROM in any direction was found to have no association with multilevel disc space narrowing. Our study indicates that a restricted ROM in latero-flexion could potentially be a defining sign in future definitions of symptomatic spinal OA. However, since our results partially differ from previous studies, further research is needed to explore the association between active ROM and LDD.

Personal resilience among novice teachers and teacher-interns in Arab society in Israel: demographic, socio-emotional and educational characteristics

ABSTRACT Unlike previous studies that have investigated teachers’ personal resilience, the current study sought to examine its demographic characteristics and its relationships with socio-emotional and educational factors, and to consider differences in personal resilience between novice teachers and teacher-interns with low, medium and high levels of personal resilience. The participants were 298 novice teachers and teacher-interns in Arab schools in the north of Israel, who filled out questionnaires that included demographic details, and measures of personal resilience, subjective happiness, positive and negative affect, self-esteem, social anxiety, and teaching motivation. The findings indicated significant differences between the participants on the relationship between personal resilience and teaching status, teaching internship and teaching seniority. In addition, a significant positive correlation was found between personal resilience and subjective happiness, but negative correlations were found between personal resilience and negative affect, social anxiety, social fear, and social avoidance. Significant differences were found between three categories (low, medium and high personal resilience) of novice teachers and teacher-interns for social avoidance, social anxiety, general affect, negative affect, and teaching motivation. The authors concluded that workshops for the mentioned teachers should focus primarily on increasing their personal resilience, which is crucial for their optimal integration into the education system.

Academic buoyancy and fear of failure differences among university students: Null findings

Academic buoyancy refers to a student's adaptive response for dealing with academic-related setbacks and challenges that are typical in the ordinary course of school life. Fear of failure, known also as fear avoidance, is the tendency for students to be uncertain about their ability to avoid failures and achieve success. Both constructs have been associated with students' academic outcomes. Herein, we examine whether there were differences in these constructs associated either with students' time in the academic setting (i.e., first generation student or graduate level student) or type of challenges experienced (i.e., as a student of color or primary language other than English). Specifically, in using online surveys, we investigated the relation between academic buoyancy and fear of failure among university students (N = 122) from a public university in the southwestern United States. Supporting earlier research, when examining the association between academic buoyancy and fear of failure across all participating students, we found academic buoyancy was negatively related to fear of failure. When examining whether there were differences in academic buoyancy or fear of failure across either student experience (i.e., degree level or first-generation student status) or types of challenges related to being a student whose primary language is a language other than English or being a student of color, we found insufficient evidence of differences. This suggests that regardless of college-generational status, degree level, primary language, and racial/ethnic backgrounds, students reported similar levels of academic buoyancy and fear of failure. Findings extend the limited literature on academic buoyancy and fear of failure in higher education.

Preliminary Feasibility of a Novel Mind-Body Program to Prevent Persistent Concussion Symptoms Among Young Adults With Anxiety: Nonrandomized Open Pilot Study.

Concussions are common, particularly among young adults, and often are associated with persistent, debilitating, and hard-to-treat symptoms. Anxiety and concussion symptoms often amplify each other, and growing evidence indicates that anxiety plays a key role in symptoms persistence after concussion. Targeting anxiety early after concussion may be a promising means of helping prevent persistent concussion symptoms in this population. We developed the Toolkit for Optimal Recovery after Concussion (TOR-C), the first mind-body program tailored for young adults with a recent concussion and anxiety, aiming to prevent persistent concussion symptoms. This study aims to conduct an open pilot of TOR-C to test preliminary feasibility, signal of change in measures, and treatment perceptions. Five young adults (aged 18-24 years) attended 4 weekly one-on-one live video sessions with a clinician. Participants completed questionnaires measuring treatment targets (ie, pain catastrophizing, mindfulness, fear avoidance, limiting behaviors, and all-or-nothing behaviors) and outcomes (ie, postconcussive symptoms, physical function, anxiety, depression, and pain) at baseline, immediately following the intervention, and 3 months after intervention completion. At the conclusion of the program, participants attended a qualitative interview and provided feedback about the program to help optimize study content and procedures. Feasibility markers were excellent for credibility and expectancy (5/5, 100% of participants scored above the credibility and expectancy scale midpoint), client satisfaction (4/5, 80% of participants scored above the Client Satisfaction Questionnaire midpoint), therapist adherence (97% adherence), acceptability of treatment (5/5, 100% of participants attended 3 or more sessions), adherence to homework (87% home practice completion), and feasibility of assessments (no measures fully missing). The feasibility of recruitment was good (5/7, 71% of eligible participants agreed to participate). There were preliminary signals of improvements from pre-post comparisons in treatment targets (d=0.72-2.20) and outcomes (d=0.41-1.38), which were sustained after 3 months (d=0.38-2.74 and d=0.71-1.63 respectively). Exit interviews indicated overall positive perceptions of skills and highlighted barriers (eg, busyness) and facilitators (eg, accountability) to engagement. TOR-C shows preliminary feasibility, is associated with a signal of improvement in treatment targets and outcomes, and has the potential to support recovery from concussion. The quantitative findings along with the qualitative feedback obtained from the exit interviews will help optimize TOR-C in preparation for an upcoming randomized controlled trial of TOR-C versus an active control condition of health education for concussion recovery.

E-Health Interventions for Managing Spine Pain—Benefits for Pain, Quality of Life, Catastrophizing and Fear Avoidance Beliefs: An Overview of Systematic Reviews With Meta-Analysis

OBJECTIVE: To summarize the effectiveness of eHealth interventions for improving pain, physical disability, psychological factors, and the quality of life for people with spine pain. DESIGN: Overview of systematic reviews. LITERATURE SEARCH: CINAHL, Embase, PubMed, and SPORTDiscus e-databases were searched. STUDY SELECTION CRITERIA: Systematic reviews with meta-analysis of randomized clinical trials evaluating any type of eHealth were included. DATA SYNTHESIS: AMSTAR 2 was used to assess the methodological quality of included reviews. The degree of overlap between reviews was calculated. RESULTS: Sixteen systematic reviews were included. Of them, thirteen reviews were exclusively focused on back pain or low back pain. Exercise and psychological interventions were the primary contents of eHealth interventions. In general, eHealth interventions based on physical exercise may improve the quality of life of people with low back pain. eHealth interventions based on cognitive behavioral therapy may reduce pain catastrophizing and fear-avoidance beliefs for physical activity for people with low back pain. eHealth interventions based on multidisciplinary approaches including physical exercise may reduce low back pain. Few systematic reviews used the GRADE system to evaluate the certainty of evidence, and few specified the content of eHealth interventions. CONCLUSION: eHealth interventions may improve the quality of life, pain catastrophizing, fear-avoidance beliefs, for people with low back pain. It is unclear, based on available systematic reviews, how clinicians should deliver eHealth interventions for people with spine pain (e.g., neck pain or low back pain).

A Feasibility Randomized Controlled Trial of the Toolkit for Optimal Recovery after Concussion: A Live Video Program to Prevent Persistent Concussion Symptoms in Young Adults with Anxiety

ObjectivesTo assess the feasibility of the Toolkit for Optimal Recovery after Concussion (TOR-C), the first mind-body program aiming to prevent persistent concussion symptoms among young adults with anxiety, and an active control (Health Enhancement after Concussion; HE-C). We also tested preliminary improvements in outcome measures and putative mechanistic targets. DesignSingle-blind, 2-arm, randomized controlled trial.Setting: Academic medical center in the US Northeast. ParticipantsFifty young adults (ages 18-35) with a recent concussion (3-10 weeks prior) and anxiety (≥5 on the GAD7 questionnaire). InterventionsBoth interventions consisted of four 45-minute 1:1 sessions with a clinician over Zoom. TOR-C (n=25) taught mind-body, cognitive-behavioral, and return-to-activity skills. HE-C (n=25) taught health education (e.g., sleep, nutrition) without skills. Main Outcome MeasuresPrimary: feasibility outcomes (e.g., recruitment, credibility, expectancy, acceptability, safety, feasibility of assessments, fidelity, satisfaction, TOR-C homework adherence) with a-priori-set benchmarks. Secondary: intervention outcomes were concussion symptoms (PCSS), physical function (WHODAS), anxiety (GAD7/HAD-A), depression (HADS-D) and pain (NRS). TOR-C mechanistic targets were pain catastrophizing (PCS), mindfulness (CAMS-R), fear avoidance (FAB-TBI), limiting behavior and all-or-nothing behavior (BRIQ). ResultsBoth interventions met all feasibility benchmarks and were associated with significant improvements in outcomes (concussion symptoms, physical function, anxiety, depression and pain; d=0.44-1.21) and TOR-C mechanistic targets (pain catastrophizing, mindfulness, fear-avoidance, and limiting behavior; Cohen's d=0.41-1.24). Improvements in all-or-nothing behavior were only significant in TOR-C (d=0.52). Improvements in all mechanistic targets except all-or-nothing behavior following TOR-C were significantly associated with improvements in at least one outcome. ConclusionFindings provide strong support for the feasibility of TOR-C and HE-C, and preliminary evidence for improvements in mechanistic targets and outcomes. Findings inform a future fully-powered RCT testing efficacy of TOR-C vs. HE-C.

Postoperative early initiation of sequential exercise program in preventing persistent spinal pain syndrome type-2 after modified transforaminal lumbar interbody fusion: a prospective randomized controlled trial.

This prospective randomized controlled trial aimed to investigate the impact of early postoperative sequential motor control (starting first day post-operatively) and core stabilization training (starting fifth week post-operatively) compared to conventional exercise (starting fifth weeks post-operatively) on the risk of developing persistent spinal pain syndrome type-2 (PSPS-T2). 395 patients with lumbar degenerative diseases (LDDs) undergoing modified transforaminal lumbar interbody fusion and a 12-week postoperative exercise program (sequential vs. conventional exercise: 214 vs. 181) were evaluated for low back pain (LBP) intensity, Oswestry Disability Index (ODI), pressure pain threshold (PPT), temporal summation (TS), fatty infiltration of paraspinal muscles, transversus abdominis (TrA) activation capacity and Fear-Avoidance Beliefs Questionnaire (FABQ) pre-operatively, 3 months post-operatively, and 1 year post-operatively. At 3-month postoperative assessment, LBP in sequential exercise group were lower than those in conventional exercise group (P < 0.05), and sequential-exercise patients had greater local-area PPTs, lower TS, lower TrA activation capacities and less fatty infiltration of erector spinae than did the conventional-exercise patients (P < 0.05). At 1-year postoperative assessment, fewer sequential-exercise patients had PSPS-T2 compared with conventional-exercise patients (11/214 vs. 20/181; P < 0.05). LBP at rest and FABQ were lower in sequential-exercise patients than conventional-exercise patients (P < 0.05). Furthermore, both PPT and TS at 1-year postoperative assessment were associated with these measurements at 3-month postoperative assessment in patients with PSPS-T2 (P < 0.05). Postoperative sequential exercise has more positive effects to avoid PSPS-T2 than conventional exercise in patients with LDDs possibly because of its advantages in improving central and peripheral sensitization.

The Correlation Between Fear Avoidance Beliefs and Physical Activity in Unilateral Vestibulopathies

The Correlation Between Fear Avoidance Beliefs and Physical Activity in Unilateral Vestibulopathies

Pain sensitization and pain-related psychological factors in patients with temporomandibular disorders: an observational cross-sectional study.

There is conflicting evidence on how central processing impairments affect patients with temporomandibular disorders (TMD). Moreover, there is sparse research on the assessment of endogenous pain modulation in this population through conditioned pain modulation (CPM) testing. The main objective of this observational study was to evaluate the possible differences between myofascial TDM patients and healthy pain-free controls on psychophysical variables suggestive of central processing impairments (including temporal summation (TSP), pressure pain threshold (PPT) and conditioned pain modulation (CPM)). This is a cross-sectional observational study including a sample of patients with TMD and pain-free controls recruited from private and university clinics in Spain. Outcome measures included local and distal PPTs, temporal summation, conditioned pain modulation and psychological factors of depression, anxiety, kinesiophobia, fear avoidance beliefs and pain catastrophizing. Fifty-nine patients with TMD of myofascial origin (32 years [IR: 25-43]) and 30 healthy, pain-free controls (29.5 years [IR: 25-41]) participated in the study and completed the evaluations. Patients with TMD showed significantly reduced CPM (p = 0.001; t = 3.31) and both local and distal PPTs (p < 0.05) when compared with controls, after adjusting for the influence of age and sex. TSP did not show any difference between the groups (p = 0.839; Z = 0.20). All psychological factors were higher in patients with TMD (p < 0.005), except for anxiety (p = 0.134). Patients with myofascial TMD included in this study exhibited signs of altered central processing, linked to impaired descending pain modulation, distal hyperalgesia and psychological factors like depression, kinesiophobia, fear avoidance beliefs and pain catastrophizing but not anxiety.

Treating Anxiety-Based Cognitive Distortions Pertaining to Somatic Perception for Better Chronic Pain Outcomes: A Recommendation for Better Practice in the Present Day and the Cyber Age of Medicine.

Anxiety-based cognitive distortions pertaining to somatic perception (ABCD-SPs)-primarily catastrophizing, fear avoidance, and kinesiophobia-have been repeatedly linked to worsening chronic, non-cancer pain (CNCP) outcomes of increased disability, amplified pain, ineffective opioid use, and opioid misuse. Several studies have suggested that treating ABCD-SPs can improve pain outcomes, yet identification and targeting of ABCD-SPs are not part of the standard medical pain assessment and treatment plan. Utilizing a narrative review of proposed mechanisms, published patient perspectives, and study correlations connecting these cognitive distortions with CNCP outcomes, an approach for better practice in the delivery of standard medical CNCP care can be deduced and formulated into a Belief and Behavior Action Plan (BBAP) for medical clinicians treating CNCP to implement into initial and maintenance care planning. These recommendations require relatively few resources to implement and have the potential to disseminate more effective CNCP treatment on a large scale now and in the future with the new frontier of cognitive computing in medicine.

Translation, cross-cultural adaptation, and psychometric testing of the STarT musculoskeletal tool into Yoruba language among persons with low back pain

BackgroundThe STarT Musculoskeletal (MSK) tool is a validated tool used to stratify patients with musculoskeletal disorder, as a guide to applying intervention and prognosticating outcomes. Only few translations and cultural adaptations of it exist. The availability of the tool in local and indigenous languages may help improve comprehensibility and usage among patients. This study was aimed to translate and cross-culturally adapt the STarT MSK tool into the Yoruba language, and to determine its psychometric properties.MethodsThe first stage of this study involved translation of the English STarT MSK into the the Yoruba language following the Beaton criteria. A total of 55 respondents with low- back pain attending a University Teaching Hospital participated in the validity testing, while 25 patients responded in the reliability test of the tool. The Quadruple Visual Analogue Scale (QVAS) and the Fear Avoidance Belief Questionnaire (FABQ) were used for the convergent and the discriminant validity of the tool.ResultsThe mean age of the respondents was 52.13 ± 13.21 years. The Yoruba version of the STarT MSK (STarT MSK–Y) had an acceptable concurrent validity (r = 0.993; p = 0.001). The discriminant validity of STarT MSK–Y with FABQ yielded correlation co-efficient scores of r = 0.287; p = 0.034 and r = 0.033; p = 0.810 for FABQ-Work and FABQ-physical activities. The result indicated that STarT MSK–Y had fair discriminant validity with FABQ-work and a weak correlation with the FABQ-physical activities. The convergent validity of STarT MSK–Y indicated significant correlations with all domains and global score of the QVAS (r = 0.727; p = 0.001). The test- retest reliability and internal consistency (Cronbach’s alpha = α) of the STarT MSK–Y yielded ICC = 1.00 and α = 0.97 for the global score of the items, respectively. The factor loading for five items were satisfactory ranging from 0.46 to 0.83.ConclusionThe STarT MSK–Y has acceptable validity and reliability and can be used as a valid assessment tool among Yoruba-speaking patients with low back pain.

Effectiveness of an interactive online group intervention based on pain neuroscience education and graded exposure to movement in breast cancer survivors with chronic pain: a randomised controlled trial

PurposeTo evaluate the effectiveness, compared with usual care, of an interactive online group programme combining pain neuroscience education (PNE) and graded exposure to movement (GEM) for improving quality of life and pain experience in breast cancer survivors with chronic pain.MethodsThis single-blind randomised controlled trial included a sample of 49 breast cancer survivors who were randomly assigned to two groups (experimental: n = 22 and control: n = 27). The experimental group received a 12-week person-centred online programme based on pain neuroscience education and therapeutic yoga as gradual exposure to movement, while the control group continued with their usual care. The primary outcome was quality of life (FACT–B + 4); the secondary outcomes were related to the experience of chronic pain (pain intensity, pain interference, catastrophizing, pain self-efficacy, kinesiophobia, and fear avoidance behaviours). All variables were assessed at four time points (T0, baseline; T1, after PNE sessions; T2, after yoga sessions; T3, at 3-month follow-up). For data analysis, ANOVA (2 × 4) analysis of variance (95% CI) was used when outcomes were normally distributed. If not, within-group and between-group comparisons were calculated.ResultsThirty-six participants were included in the analysis (control group, 22; experimental group, 14). A significant time * group effect was observed in favour of the experimental group regarding the global quality of life score (p = 0.010, ηp2 = 0.124). Significant differences in favour of the experimental group were observed for pain intensity, pain interference, catastrophizing, and pain self-efficacy. These differences persisted at follow-up.ConclusionsAn online intervention based on PNE and GEM appears to be more effective than usual care for improving quality of life in breast cancer survivors with chronic pain, as a time per group interaction was reported. In addition, the intervention also significantly improved the participants’ experience of chronic pain. However, due to the study limitations further research is needed.Trial record: NCT04965909 (26/06/2021).

Criterion validity of a single-item measure of fear avoidance behavior following mild traumatic brain injury

Maladaptive coping such as fear avoidance behavior can prolong recovery from mild traumatic brain injury (mTBI). Routine assessment of fear avoidance may improve management of mTBI. This study aimed to validate a single-item measure of fear avoidance to make its assessment more pragmatic. The present study is a secondary analysis of a clinical trial that involved adults with persistent post-concussion symptoms (N = 90, 63% female). Participants completed the single-item fear avoidance rating, a validated legacy measure of fear avoidance (Fear Avoidance Behavior after Traumatic Brain Injury; FAB-TBI), and measures of anxiety (General Anxiety Disorder-7), depression (Patient Health Questionnaire-9), post-concussion symptoms (Rivermead Postconcussion Symptoms Questionnaire), and disability (World Health Organization Disability Assessment Schedule 12.0). Questionnaires were completed twice, at baseline (mean 18.1 weeks post injury) and again 12–16 weeks later following study-delivered rehabilitation in addition to usual care. We analyzed the associations (Spearman’s correlations) and agreement (weighted Kappa) between the single-item and FAB-TBI at baseline, posttreatment, individual FAB-TBI item scores, and the change in scores between baseline and posttreatment. In addition, we examined correlations between the single-item fear avoidance measure and related constructs, including anxiety, depression, post-concussion symptoms, and disability. The single-item fear avoidance measure correlated strongly with the FAB-TBI both at baseline and following treatment (ρ = 0.63 − 0.67, p < .001), and moderately with FAB-TBI item scores (ρ = 0.4 − 0.6). The correlation between the change in these scores from baseline to posttreatment was moderate (ρ = 0.45, p < .001). Agreement between the single-item fear avoidance measure and discretized FAB-TBI scores was moderate (κ = 0.45 − 0.51). Before and after treatment, the single-item fear avoidance measure correlated moderately with anxiety (ρ = 0.34), depression (ρ = 0.43), post-concussion symptoms (ρ = 0.50), and disability (ρ = 0.43). The FAB-TBI was more strongly correlated with these measures (ρ = 0.53 − 0.73). In summary, the present study supports the criterion validity of the single-item fear avoidance measure. This measure may be a useful screening and monitoring tool for patients with mTBI but is not a substitute for the FAB-TBI questionnaire.

Chronic Low Back Pain Causal Risk Factors Identified by Mendelian Randomization: a Cross-Sectional Cohort Analysis.

There are a number of risk factors- from biological, psychological, and social domains- for non-specific chronic low back pain (cLBP). Many cLBP treatments target risk factors on the assumption that the targeted factor is not just associated with cLBP but is also a cause (i.e, a causal risk factor). In most cases this is a strong assumption, primarily due to the possibility of confounding variables. False assumptions about the causal relationships between risk factors and cLBP likely contribute to the generally marginal results from cLBP treatments. The objectives of this study were to a) using rigorous confounding control compare associations between modifiable causal risk factors identified by Mendelian randomization (MR) studies with associations in a cLBP population and b) estimate the association of these risk factors with cLBP outcomes. Cross sectional analysis of a longitudinal, online, observational study. 1,376 participants in BACKHOME, a longitudinal observational e-Cohort of U.S. adults with cLBP that is part of the NIH Back Pain Consortium (BACPAC) Research Program. Pain, Enjoyment of Life, and General Activity (PEG) Scale. Five risk factors were selected based on evidence from MR randomization studies: sleep disturbance, depression, BMI, alcohol use, and smoking status. Confounders were identified using the ESC-DAG approach, a rigorous method for building directed acyclic graphs based on causal criteria. Strong evidence for confounding was found for age, female sex, education, relationship status, financial strain, anxiety, fear avoidance and catastrophizing. These variables were used to determine the adjustment sets for the primary analysis. Potential confounders with weaker evidence were used for a sensitivity analysis. Participants had the following characteristics: age 54.9 ± 14.4 years, 67.4% female, 60% never smokers, 29.9% overweight, 39.5% obese, PROMIS sleep disturbance T-score 54.8 ± 8.0, PROMIS depression T-score 52.6 ± 10.1, Fear-avoidance Beliefs Questionnaire 11.6 ± 5.9, Patient Catastrophizing Scale 4.5 ± 2.6, PEG 4.4 ± 2.2. In the adjusted models alcohol use, sleep disturbance, depression, and obesity were associated with PEG, after adjusting for confounding variables identified via a DAG constructed using a rigorous protocol. The adjusted effect estimates- the expected change in the PEG outcome for every standard deviation increase or decrease in the exposure (or category shift for categorical exposures) were the largest for sleep disturbance and obesity. Each SD increase in the PROMIS sleep disturbance T-score resulted in a mean 0.77 (95% CI: 0.66, 0.88) point increase in baseline PEG score. Compared to participants with normal BMI, adjusted mean PEG score was slightly higher by 0.37 points (95% CI: 0.09, 0.65) for overweight participants, about 0.8 to 0.9 points higher for those in obesity classes I and II, and 1.39 (95% CI: 0.98, 1.80) points higher for the most obese participants. Each SD increase in the PROMIS depression T-score was associated with a mean 0.28 (95% CI: 0.17, 0.40) point increase in baseline PEG score, while each SD decrease in number of alcoholic drinks per week resulted in a mean 0.12 (95%CI: 0.01, 0.23) increase in baseline PEG score in the adjusted model. Several modifiable causal risk factors for cLBP - alcohol use, sleep disturbance, depression, and obesity- are associated with PEG, after adjusting for confounding variables identified via a DAG constructed using a rigorous protocol. Convergence of our findings for sleep disturbance, depression, and obesity with the results from MR studies, which have different designs and biases, strengthens the evidence for causal relationships between these risk factors and cLBP (1). The estimated effect of change in a risk factors on change in PEG were the largest for sleep disturbance and obesity. Future analyses will evaluate these relationships with longitudinal data.

Graded exposure therapy for adults with persistent symptoms after mTBI: A historical comparison study

ABSTRACT Fear avoidance behaviour is associated with slow recovery from mild traumatic brain injury (mTBI). This study is a preliminary evaluation of graded exposure therapy (GET), which directly targets fear avoidance behaviour, for reducing post-concussion symptoms (PCS) and disability following mTBI. In a historical comparison design, we compared two groups from independent randomized trials. The GET + UC group (N = 34) received GET (delivered over 16 videoconference sessions) in addition to usual care (UC). The historical comparison group (N = 71) received UC only. PCS severity (Rivermead Post Concussion Symptoms Questionnaire; RPQ) and disability (World Health Organization Disability Assessment Schedule; WHODAS 2.0 12-item) were measured at clinic intake (M = 2.7, SD = 1.1 months after injury) and again at M = 4.9 (SD = 1.1) months after injury. Between-group differences were estimated using linear mixed effects regression, with a sensitivity analysis controlling for injury-to-assessment intervals. The estimated average change on the RPQ was −14.3 in the GET + UC group and −5.3 in the UC group. The estimated average change on the WHODAS was −5.3 in the GET + UC group and −3.2 in the UC group. Between-group differences post-treatment were −5.3 on the RPQ and −1.5 on the WHODAS. Treatment effects were larger in sensitivity analyses. Findings suggest that a randomized controlled trial is warranted.

Applying Clinical Practice Guidelines on Chronic Headaches, Neck Pain, and Chest Symptoms: A Single Case Report

BACKGROUND: Neck pain and headaches are common conditions in physical therapy practice. Clinical practice guidelines (CPG’s) are forms of evidence designed to decrease practice variability and guide care. CPG recommendations are general, with few specific tactics recommended, which could be a factor in their limited adoption and poor application. This case report demonstrates an example of implementing the Academy of Orthopedic Physical Therapy (AOPT) Neck Pain Revision CPG while also highlighting limitations and areas lacking specificity. CASE PRESENTATION: The patient was a 37-year-old female with neck pain, chest pain, and headaches. She was treated following the recommendations within the AOPT CPG along with psychologically informed practice. The Neck Disability Index (NDI), Patient Specific Functional Scale (PSFS), Fear Avoidance Beliefs Questionnaire (FABQ), symptoms, and impairments were measured at evaluation, discharge, and 2 months post discharge. OUTCOMES: Clinically meaningful improvements in NDI and PSFS scores, improved cervical endurance, scapular strength, and cervical motor control were observed at discharge. Additional improvements in NDI scores were seen at 2-months post discharge. DISCUSSION: While the CPG promotes the use of manual therapy, exercise and general screening, the authors demonstrate specific techniques for identifying and managing fear avoidance behavior with cognitive and graded exposure techniques.

The Effects of Subchronic Methamphetamine Administration on the NLRP3 Inflammasome, Memory Function, and Hippocampal Morphology

Background: While it is established that addictive doses of methamphetamine correlate with inflammation-mediated neurotoxic pathways, the extent of toxicity resulting from subchronic administration at lower doses remains uncertain. Objectives: This study aimed to investigate the subtle effects of daily subchronic methamphetamine (MA) administration on neuroinflammatory processes, cognitive dimensions, gene expression, and hippocampal morphology. Methods: The experimental study employed a longitudinal design with three groups (G1B, G2B, G3B) receiving methamphetamine (5 mg/kg, intraperitoneally, once daily) for 1, 2, or 3 weeks, respectively. Corresponding control groups (G1A, G2A, G3A) received 0.2 mL of normal saline. Spatial learning, novel object recognition, and passive avoidance tests were conducted to assess spatial, recognition, and fear avoidance memories. Hippocampal morphology was evaluated using Nissl staining, and the expressions of NLRP3, ASC, and caspase-1 genes were measured as markers of neuroinflammation. Results: Statistical analyses, including one-way and two-way ANOVA, showed that subchronic low-dose administration of MA led to significant activation of the inflammasome (NLRP3, ASC, and caspase-1), which may have resulted in pyramidal cell death in the hippocampus. The hippocampal structure in the CA1 region was completely disrupted. Spatial memory and passive avoidance learning were impaired in the MA groups, while recognition memory remained unaffected. Conclusions: The findings suggest that prolonged administration of 5 mg/kg of methamphetamine may be associated with significant inflammasome activation, pyramidal cell death, and mild cognitive decline. Contrary to previous evidence, even lower doses of methamphetamine taken over an extended period could be neurotoxic.

The impact of fear of attacks on pain-related disability in cluster headache: Insights from the fear avoidance model.

This study utilized the theoretical framework of the "fear avoidance model" (FAM) and investigated the role of fear of attack in pain-related disability. To this end, a measurement specific to cluster headache (CH) was used to investigate whether fear of attacks, alongside attack frequency, is a significant predictor of pain-related disability in CH. Cluster headache substantially impacts daily functioning, yet empirical research exploring specific contributing factors is limited. A cross-sectional online survey was undertaken in patients with CH, gathering sociodemographic, clinical data, and responses on the Cluster Headache Scale and the Depression, Anxiety and Stress Scale. Analysis of data from 640 patients (chronic CH: 287/640 [44.8%]; female: 264/640 [41.3%]; male: 373/640 [58.3%]; gender diverse: three of 640 [0.5%]; age range: 18-86 years; mean [standard deviation] Cluster Headache Scales subscale disability score: 36.9 [9.8]; out of 869 respondents) revealed that both attack frequency and fear of attacks significantly predicted pain-related disability (p < 0.001, percentage of variance explained: R2 = 0.24). More variance was explained by fear of attacks (R2 = 0.22) than by attack frequency (R2 = 0.02). This relationship remained significant even when controlling for depression and anxiety, which were also identified as independent predictors of pain-related disability (p < 0.001, R2 = 0.44). This study emphasizes the relevance of psychological factors in CH-related disability. Fear of attacks was found to be an independent predictor, while attack frequency was of minor relevance. Empirical investigation of the FAM in CH could improve the understanding of the mechanisms underlying disability and contribute to the development of CH-specific interventions.

Effects of Fu’s subcutaneous needling on clinical efficacy and psychological cognitive characteristics in patients with chronic non-specific low back pain: A randomized controlled trial

Background and purposeLow back pain (LBP) is a major global public health problem. Evidence shows that LBP is also related to cognitive, psychological, and lifestyle factors. Fu’s subcutaneous needling (FSN) has been used for the treatment of musculoskeletal problems for many years. This prospective randomized controlled trial aimed to evaluate the clinical efficacy and fear avoidance beliefs of FSN in the treatment of patients with chronic non-specific LBP. Material and methodsNinety participants with chronic non-specific LBP were randomly divided into the FSN and the traditional acupuncture (TA) groups (n = 45) and received either FSN or TA treatment for three consecutive days from December 2021 to March 2023. The primary outcome was pain intensity measured by the visual analogue scale (VAS). Secondary outcomes were trunk extensor endurance (TEE), lumbar range of motion (ROM), and the Fear Avoidance Beliefs Questionnaire (FABQ). Outcome measurements were made before the first treatment and after each treatment. Follow-up assessments of VAS and FABQ scores were conducted one month after treatment. ResultsThe FSN group had significantly lower VAS and FABQ scores at each time point after intervention compared to the TA group (P < 0.01). The scores of TEE and lumbar ROM were higher in the FSN group than those in the TA group (P < 0.01). Repeated measures analysis of variance (ANOVA) showed significant time effects, group effects, and interaction effects for VAS, TEE, lumbar ROM, and FABQ in both groups (P < 0.01). One month after treatment, the FSN group had significantly lower VAS and FABQ scores compared to the TA group (P < 0.05). ConclusionThis study suggested that FSN was superior to TA in terms of clinical efficacy and fear-avoidance beliefs in the treatment of chronic non-specific LBP. FSN could be used as an effective clinical treatment.

Identifying phenotypes in persons with temporomandibular disorders, using latent class analyses: Temporomandibular disorders and phenotypes.

The heterogeneity of persons with temporomandibular disorders (TMD) and the lack of effective treatments have called for a biopsychosocial model and the development of a more personalised treatment approach. Emphasis on phenotypes might be a beneficial approach. Identifying phenotypes among persons with TMD using potential prognostic factors, including personal characteristics and responses to clinical tests. Additionally, examining the distribution of TMD diagnoses within the identified phenotypes. A cross-sectional study including 208 persons (85% females) seeking physiotherapy for problems in the temporomandibular area. All participants were examined clinically and answered questionnaires electronically. The phenotypes were identified using latent class analysis based on seven potential prognostic factors selected within pain, function and psychological domains. Table analysis was used to explore the distribution of TMD diagnoses within the identified phenotypes. Most participants fit into one of three identified phenotypes. Phenotype 1 (32%) was characterised by functional disability, low psychosocial scores and low risk for developing chronicity and future work disability; Phenotype 2 (29%) by parafunctional habits, low psychosocial score and seeking treatment to reduce pain; and Phenotype 3 (39%) by high levels of mental distress, fear avoidance and a large risk of future work disability. Intra-articular disorders dominated Phenotype 1, myalgia and TMD-related headache Phenotype 2, while Phenotype 3 included all the different TMD diagnoses. The knowledge about the three identified phenotypes might be useful for clinicians treating persons with TMD and for the development of preventive strategies and more personalised treatment.
