Meaningful contributions of rehabilitation for people with persistent pain; a reflexive thematic analysis.

PURPOSE: This study aims to explore the meaningful contributions of rehabilitation for participants living with persistent pain. MATERIALS AND METHODS: A phenomenological methodology was used. Thirteen purposefully selected participants, who self-identified as substantially improved from persistent pain due to rehabilitation, were interviewed in-depth. Data were analyzed using reflexive thematic analyses. RESULTS: Participants included three men and ten women, age ranging from 22-69 years, pain duration was 2-30 years. Seven interconnected themes were developed: 1) indication of negative pain and health care experiences, 2) supporting working alliance with healthcare professionals, 3) Pain Dialogue, 4) improved self-awareness and self-regulation, 5) different view on pain, 6) autonomy and personal growth and 7) hope and new perspective. Integration of these themes provided a framework for understanding meaningful contributions of rehabilitation from the participants' perspective. CONCLUSIONS: The study identified seven interconnected themes enhancing meaningful contributions of rehabilitation for participants who have substantially improved from persistent pain. These findings provide a novel conceptual understanding of how rehabilitation can foster recovery. The themes strongly support person-centred care, an understanding of Pain Dialogue and personal growth through the lens of the lived experience. The quality of the therapeutic relationship is considered a central vehicle for improved health outcomes.

A rehabilitation participant perspective can contribute to better outcomes in pain rehabilitation.A shift from a pain-centred to a person-centred approach should be considered to enhance meaningful contributions of rehabilitation.Pain Education should be reconceptualized into Pain Dialogue.The quality of the therapeutic relationship can be regarded as a key driver for the effectiveness of person-centred care and Pain Dialogue.

Higher levels of physical activity are associated with less evasive coping, better physical function and quality of life in patients with axial spondyloarthritis.

OBJECTIVE: To evaluate daily physical activity (PA) in relation to psychosocial factors, such as anxiety, depression and different types of coping strategies, as well as patient- and disease-related factors in patients with axial spondyloarthritis (axSpA). METHODS: Consecutive outpatients from the Groningen Leeuwarden AxSpA (GLAS) cohort completed the modified Short Questionnaire to assess health-enhancing PA (mSQUASH), Hospital Anxiety and Depression Scale (HADS) and Coping with Rheumatic Stressors (CORS) questionnaires, as well as standardized patient- and disease-related assessments. Univariable and multivariable linear regression analyses and comparison of lowest and highest PA tertiles were performed to explore associations between the HADS, CORS, patient- and disease-related factors and PA. RESULTS: In total, 84 axSpA patients were included; 60% male, mean age 49 (SD ±14) years, median symptom duration 20 (25th-75th percentiles: 12-31) years, mean ASDAS 2.1 (±1.0). Higher PA levels were significantly associated with better scores on patient-reported disease activity (BASDAI), physical function (BASFI) and quality of life (ASQoL). Furthermore, higher levels of PA were associated with less impact of axSpA on wellbeing and lower HADS depression scores. In the multivariable linear regression model, less use of the coping strategy 'decreasing activities' (ß: -376.4; p 0.003) and lower BMI (ß:-235.5; p: 0.030) were independently associated with higher level of PA. Comparison of patients from the lowest and highest PA tertiles showed results similar to those found in the regression analyses. CONCLUSION: In this cohort of axSpA patients, higher levels of daily PA were associated with better patient-reported outcomes and lower depression scores. Additionally, the passive coping strategy "decreasing activities" and lifestyle factor BMI were independently associated with PA. Besides anti-inflammatory treatment, coping strategies and lifestyle should be taken into account in the management of individual axSpA patients. Incorporating these aspects into patient education could increase patient awareness and self-efficacy. In the future, longitudinal studies are needed to better understand the complex relationship between patient-, disease- and psychosocial factors associated with daily PA.

Patients' Perspectives on Axial Pain in Relation to Inflammation and Structural Damage in a Large Cohort of Axial Spondyloarthritis Patients.

OBJECTIVE: The objective of this study was to explore to what extent patients with axial spondyloarthritis (axSpA) link experienced pain in the neck, back, and hips to inflammation and/or structural damage. METHODS: Patients from the Groningen Leeuwarden Axial Spondyloarthritis (GLAS) cohort visiting the outpatient clinic between 2016 and 2019 filled out two additional questions in relation to the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) question 2: (1) "To what extent do you think the pain you experience in your neck, back, and hips is related to inflammation caused by axSpA?" and (2) "To what extent do you think the pain you experience in your neck, back, and hips is related to damage of the spine and joints caused by axSpA?" Answers had to be depicted on a numeric rating scale from 0 (none) to 10 (very much); a difference of ≥2 points between the scores of these questions was considered clinically relevant in favor of the highest scoring question. RESULTS: A total of 688 patients with axSpA (24% with nonradiographic axSpA [nr-axSpA]) were included (62% male, mean ± SD age 48 ± 14 years, and mean ± SD Ankylosing Spondylitis Disease Activity Score [ASDAS] 2.3 ± 1.0). Seventy-five percent of patients could not link the origin of their pain, 15% linked axial pain predominantly to inflammation, and 10% linked axial pain predominantly to damage. Patients in the inflammation group were younger, had shorter symptom duration, were more frequently diagnosed with nr-axSpA, had higher ASDASCRP , had more often elevated CRP levels, had fewer comorbidities, had better spinal mobility, and had less spinal radiographic damage. CONCLUSION: In our large observational cohort, the majority of patients with axSpA could not differentiate the origin of experienced axial pain. If patients were able to link axial pain to clinical inflammation or damage, it was in concordance with clinical assessments and radiographic outcome, which may be helpful in establishing the origin of pain and supporting better patient-centered treatment decisions.

Patients' Needs Concerning Patient Education in Axial Spondyloarthritis: A Qualitative Study.

INTRODUCTION: Within the EULAR recommendations, patient education (PE) is stated as the basis of the management of axial spondyloarthritis (axSpA). However, educational needs are scarcely qualitatively studied in axSpA. Therefore, we aimed to explore experiences and needs of PE in patients with axSpA. METHODS: A phenomenological approach was used, with semi-structured in-depth interviews with patients with axSpA including broad variation in characteristics. Thematic analysis was applied. To enhance credibility, data saturation, research triangulation, peer debriefing, member checking, theoretical notes, and bracketing were performed. RESULTS: Three interrelated themes regarding PE were identified from 20 interviews: illness perception, content, and 'availability'. Illness perception affects how patients experience and process PE, which consequently influences coping strategies. Prognosis, treatment, and coaching to self-management were identified as the most important content of PE. Regarding 'availability', face-to-face PE is preferred for exploring needs, supplemented by self-education, which can be freely applied. Additionally, sufficient time and a comprehensible amount of information were important and participants emphasized the need for axSpA-tailored information for relatives and friends. Participants reported a trusting patient-healthcare provider (HCP) relationship, and multidisciplinary and interdisciplinary attunement between HCPs as prerequisites for effective PE. CONCLUSIONS: This first qualitative study exploring patients' experiences and needs of PE in axSpA revealed that prognosis, treatment, and coaching to self-management are important regarding content, and the combination of face-to-face contact and self-education the preferred modalities. It seems essential that patients' illness perceptions are taken into account for effective PE. These results add relevant insights for future PE guidelines in axSpA.

The Working Alliance Inventory's Measurement Properties: A Systematic Review.

Measurement properties of the Working Alliance Inventory (WAI) and its various translations and adaptations for specific target groups have been investigated for over 30 years. No systematic review analyzing studies on measurement properties of the WAI has been conducted to date. COnsensus-based Standards for the selection of health Measurements INstruments (COSMIN) were developed for conducting high-quality systematic reviews on measurement properties in a transparent and standardized way. Aim of this study was to systematically review studies on measurement properties of the WAI, and its adapted versions, within psychotherapy, and other healthcare contexts using COSMIN criteria. PsycINFO, Medline, and EMBASE were searched (1989-2021). In all phases of the review procedure, study selection, data extraction, risk of bias assessment, rating of the quality of measurement properties, and rating of the quality of evidence for measurement properties, disagreement between reviewers was resolved by discussion. Results on validity, internal structure, reliability, construct validity, and responsiveness were analyzed. In total 66 studies were included. In most studies, evidence for measurement properties was according to COSMIN criteria, insufficient, lacking, or conflicting. Content validity was rated insufficient because neither patients nor healthcare professionals were involved in the development and validation process. Hence evidence for content validity of the WAI is unknown. Conflicting evidence was found for structural validity. Evidence for internal consistency could not be established. Limited evidence was found for inter-rater reliability and convergent validity. Conflicting evidence was also found for test-retest reliability and divergent validity. COSMIN criteria exposed persistent problems in validation studies of the WAI. These findings may indicate that measurement properties of the WAI are not up to current standards, or that COSMIN criteria may be less appropriate for assessing measurement properties of the WAI, or it could indicate both. The results of this systematic review suggest that WAI outcomes should be interpreted with caution and further research is needed regarding the content validity and hypotheses development. For the future, the theoretical framework underlying the measurement of the working alliance needs to be studied in psychotherapy and other health contexts, and tested in methodologically sound studies.

Differences in characteristics, health status and fulfillment of exercise recommendations between axial spondyloarthritis patients with and without supervised group exercise.

OBJECTIVE: Since decades, supervised group exercise (SGE) is recommended for people with axial spondyloarthritis (axSpA). This study examines if weekly SGE contributes to fulfillment of exercise recommendations in axSpA patients. METHODS: Cross-sectional data from three studies with axSpA patients in The Netherlands, including two with outpatient populations (n = 196 and n = 153) and one with SGE participants (n = 128), were analysed. Sociodemographic and disease characteristics, SGE participation, health status (ASAS Health Index), spinal mobility and fulfillment of the recommendations for leisure-time aerobic (≥150 min/week moderate-intensity or ≥75 min/week vigorous-intensity) and strength and mobility (≥2 sessions/week) exercise (measured with SQUASH-questionnaire) were assessed. Differences between patients with and without SGE were analysed. RESULTS: In the two outpatient populations (n = 349), 17 patients (5%) used SGE. The SGE participants (n = 145) were significantly older, had longer disease duration, were less frequently employed, used less medication and had worse spinal mobility than patients without SGE (n = 332). There were no significant differences in health status. Patients with SGE fulfilled the moderate-intensity aerobic (89 % vs. 69%) and strength and mobility (44 % vs. 29%) exercise recommendations more often than patients without SGE, but the aerobic exercise recommendation was less often fulfilled with vigorous-intensity exercise (5 % vs. 12%). CONCLUSION: SGE is used by just few, especially older, axSpA patients and contributes to fulfilling recommendations for moderate-intensity, mobility and strength exercise. Both in patients with and without SGE, only a minority fulfilled the recommendations for vigorous-intensity, strength and mobility exercises. Therefore, future promotion of exercise should focus on implementing these types of exercise.

Central sensitization has major impact on quality of life in patients with axial spondyloarthritis.

INTRODUCTION: Persistent pain has large potential impact on quality of life (QoL). During the course of the disease, many patients with axial spondyloarthritis (axSpA) report persistent pain. Central sensitization (CS) may explain part of this chronic pain. However, the role of CS in relation to QoL has been sparsely studied in axSpA. Therefore, our aim was to explore the relationship between CS and QoL in patients with axSpA. METHODS: Consecutive outpatients from the Groningen Leeuwarden axSpA (GLAS) cohort completed the Central Sensitization Inventory (CSI; range 0-100) and the AS Quality of Life (ASQoL; range 0-18). Multivariable linear regression analysis was used to explore the relationship between CSI and ASQoL scores correcting for potential confounders. RESULTS: Of the 178 included axSpA patients, mean CSI score was 38.0 ± 14.1 and 45% scored ≥40, which indicates a high probability of CS. Mean ASQoL score was 6.0 ± 5.3 and mean ASDASCRP 2.1 ± 1.0. A CSI score ≥40 was significantly associated with higher ASQoL score (mean 9.7 vs. 3.3), higher ASDASCRP (mean 2.6 vs. 1.7), female gender (60% vs. 29%) and more often entheseal involvement (61% vs. 26%). In univariable analysis, CSI score explained a large proportion of the variation in ASQoL (B = 0.06, 95%CI: 0.05-0.07; R2=0.46). This association remained significant after correction for ASDASCRP, gender, entheseal involvement, comorbidities, symptom duration, smoking status, BMI class and educational level (B = 0.04, 95%CI: 0.03-0.05). CONCLUSION: CS is strongly related to patient-reported QoL in patients with axSpA independently from other patient- and disease-related aspects.

Participants' unspoken thoughts and feelings negatively influence the therapeutic alliance; a qualitative study in a multidisciplinary pain rehabilitation setting.

PURPOSE: This study aimed to explore factors that influence participants' perceptions of the therapeutic alliance with healthcare professionals; their participation in the alliance; and their commitment to treatment in a multidisciplinary pain rehabilitation setting. MATERIALS AND METHODS: A qualitative research-design was used and 26 participants in a multidisciplinary pain rehabilitation program were interviewed in-depth. RESULTS: Initially, participants reported to be satisfied with their healthcare professionals. After deeper reflection on the therapeutic alliance, several unspoken thoughts and feelings and relational ruptures emerged. Almost all participants mentioned a history of disappointing and fragmented healthcare, and they reported on how this affected their cognitions, perceptions, and beliefs about the current program. Participants felt insufficiently empowered to voice their concerns and regularly chose to avoid confrontation by not discussing their feelings. They felt a lack of ownership of their problems and did not experience the program as person-centered. CONCLUSIONS: Several factors were found that negatively influence the quality of therapeutic alliance (agreement on bond) and efficacy of the treatment plan (agreement on goals and tasks). To improve outcomes of pain rehabilitation, healthcare professionals should systematically take into account the perceptions and needs of participants, and focus more on personalized collaboration throughout the program offered.Implications for rehabilitationDifferences in perceptions and experiences of pain, together with differences in beliefs about the causes of pain, negatively influence the therapeutic alliance.When participants and healthcare professionals operate from different paradigms, it is important that they negotiate these differences.From the perspective of participants, a clear-cut organization of healthcare that encourages collaboration is required.It is important to focus on personalized collaboration from the start and during treatment, and to recognize and discuss disagreement on diagnosis and treatment plans.During this collaboration, healthcare professionals should systematically take into account the perceptions and needs of the participants.

The mSQUASH; a valid, reliable and responsive questionnaire for daily physical activity in patients with axial spondyloarthritis.

AIM: Adaptation of the Short QUestionnaire to Assess Health-enhancing physical activity (SQUASH) in order to improve measurement properties in axSpA patients. METHODS: The original SQUASH was adapted using a qualitative stepwise approach with in-depth interviews including healthcare professionals and patients. Content validity was explored by comparing modified-SQUASH (mSQUASH) and original SQUASH. Next, mSQUASH was validated according to the OMERACT filter. International Physical Activity Questionnaire (IPAQ) was used as comparator and tri-axial accelerometer as gold standard for criterion validity and classification accuracy of intensity. Construct validity was assessed using Spearman correlations with clinical outcome assessments. For test-retest reliability, intra-class correlation coefficients (ICCs) were calculated. Responsiveness was assessed using standardized response mean (SRM), stratified by Anchor method. RESULTS: The mSQUASH measured a systematically higher activity count and had less missing values (8% vs. 16%) then SQUASH. mSQUASH correlated better with accelerometer compared to IPAQ (ρ = 0.60 vs. ρ = 0.34). Accelerometer measured most activity in light intensity, whereas mSQUASH and IPAQ predominately measured moderate intensity. Correlations with ASDAS, BASDAI, BASFI and ASQoL were better for mSQUASH then IPAQ. Test-retest reliability was good in both questionnaires. In contrast to IPAQ, responsiveness was in correspondence with self-reported changes in physical activity for mSQUASH (SRM -0.84 for improvement and 0.88 for decrease). The average completion time of the mSQUASH was 7 minutes. CONCLUSIONS: The development of the mSQUASH resulted in an easy applicable, valid, reliable and responsive questionnaire for the assessment of daily physical activity in axSpA patients, which can be used in research and daily clinical practice.

Ageing of Immune System and Response to a Live-Attenuated Herpes Zoster Vaccine in Lung Transplant Candidates.

The mean age of lung transplant recipients has significantly increased in recent decades. Elderly recipients have a higher risk of developing herpes zoster (HZ), and they have in general a worse response to vaccination than younger persons do. We investigated the relationship between the humoral and cellular immune response to a live-attenuated HZ vaccine (Zostavax®, Merck Sharp and Dohme) and the frequencies of T and B cell subsets, especially aged cell subsets (CD28-T cells and age associated B cells, ABCs). In total, 37 patients awaiting lung transplantation received one dose of Zostavax®, and peripheral blood was collected before and within 6 months after vaccination. We observed a robust immune response after vaccination. The frequencies of CD28-T cells before vaccination had no impact on the subsequent immune response to HZ vaccination. However, a higher frequency of ABCs before vaccination correlated with a lower immune response especially regarding the cellular immune response. Cytomegalovirus seropositivity was associated with increased frequencies of CD28-T cells but not with frequencies of ABCs in the patients. In conclusion, increased levels of ABCs might disturb the cellular immune response to HZ vaccination, which could lower the efficacy of such vaccination in elderly transplant recipients.

Central sensitization, illness perception and obesity should be considered when interpreting disease activity in axial spondyloarthritis.

OBJECTIVES: Many patients with axial spondyloarthritis (axSpA) report persistent pain even when treated with anti-inflammatory agents. Our aim was to explore the presence of central sensitization (CS) and different types of illness perceptions in patients with axSpA, and to assess their associations with disease activity assessments. METHODS: Consecutive outpatients from the Groningen Leeuwarden Axial Spondyloarthritis (GLAS) cohort were included. Besides standardized assessments, patients filled out the Central Sensitization Inventory (CSI), Illness Perception Questionnaire (IPQ-R) and Pain Catastrophizing Scale (PCS). Univariable and multivariable linear regression analyses were used to investigate the association between questionnaire scores, patient characteristics and disease activity assessments ASDASCRP, BASDAI and CRP. RESULTS: We included 182 patients with a mean symptom duration of 21.6 years. Mean ASDASCRP was 2.1, mean BASDAI 3.9, and median CRP 2.9. Mean CSI score was 37.8 (scale 0-100) and 45% of patients scored ≥40, indicating a high probability of CS. CSI score, IPQ-R domain identity (number of symptoms the patient attributes to their illness), and IPQ-R domain treatment control (perceived treatment efficacy), and obesity were significantly and independently associated with both ASDASCRP and BASDAI, explaining a substantial proportion of variation in these disease activity scores (R2=0.35 and R2=0.47, respectively). Only obesity was also independently associated with CRP. CONCLUSION: CS may be common in patients with long-term axSpA. CS, as well as specific illness perceptions and obesity were all independently associated with the widely used (partially) patient-reported disease activity assessments ASDASCRP and BASDAI. Treating physicians should take this into account in the follow-up and treatment of their patients.

Effect of age and sex on immune checkpoint expression and kinetics in human T cells.

BACKGROUND: Immune checkpoints are crucial molecules in maintaining a proper immune balance. Even though age and sex are known to have effects on the immune system, the interplay between age, sex and immune checkpoint expression by T cells is not known. The aim of this study was to determine whether age and sex affect immune checkpoint expression by T cells and if age and sex affect the kinetics of immune checkpoint expression following ex vivo stimulation. In this study, whole blood samples of 20 healthy young adults (YA, 9 males and 11 females) and 20 healthy older adults (OA, 9 males and 11 females) were stained for lymphocyte lineage markers and immune checkpoints and frequencies of CD28+, PD-1+, VISTA+ and CD40L+ T cells were determined. Immune checkpoint expression kinetics were studied following ex vivo anti-CD3/anti-CD28 stimulation of T cells from young and older healthy adults. RESULTS: We report an age-associated increase of CD40L + CD4+ and CD40L + CD8+ T-cell frequencies, whereas CD40+ B-cell frequencies were decreased in older adults, suggesting modulation of the CD40L-CD40 interaction with age. Immune checkpoint expression kinetics revealed differences in magnitude between CD4+ and CD8+ T cells independent of age and sex. Further analysis of CD4+ T-cell subsets revealed an age-associated decrease of especially PD-1 + CD4+ memory T cells which tracked with the female sex. CONCLUSION: Collectively, our results demonstrate that both age and sex modulate expression of immune checkpoints by human T cells. These findings may have implications for optimising vaccination and immune checkpoint immunotherapy and move the field towards precision medicine in the management of older patient groups.

Prophylactic vaccination with a live-attenuated herpes zoster vaccine in lung transplant candidates.

BACKGROUND: Herpes zoster (HZ) is caused by the reactivation of varicella-zoster virus (VZV). Patients with lung transplants are at high risk for HZ owing to their immunocompromised status and the need for lifelong immunosuppression. In this study, patients on the waiting list for lung transplantation were vaccinated by a live-attenuated HZ vaccine (Zostavax, Merck Sharp & Dohme), and the safety and immunogenicity of this vaccine were studied. METHODS: In total, 105 patients with end-stage pulmonary disease (ESPD) were enrolled (68 participants received 1 dose of Zostavax and 37 participants were enrolled as unvaccinated controls). Among them, 43 patients underwent lung transplantation and were followed up for further analysis. VZV immunoglobulin G antibody titers and VZV-specific cell-mediated immunity (CMI) on multiple time points before and after vaccination and before and after transplantation were measured. RESULTS: Immune response to Zostavax was higher in younger patients, highest within 3 months after vaccination, and not influenced by gender or type of ESPD. Age, cytomegalovirus serostatus, and immunity to VZV at baseline impacted the subsequent immune response to the vaccine. Short-term immunosuppressant treatment had strong effects on VZV CMI levels, which returned to a high level at 6 months after transplantation in vaccinated patients. Zostavax did not impact infection or rejection rate after transplantation. CONCLUSIONS: Zostavax was safe and induced a robust humoral and cellular response for patients awaiting lung transplantation regardless of the type of ESPD. Patients younger than the recommended vaccination age of over 50 years showed a strong response and could also benefit from pre-transplant immunization.

Assessing future health care practitioners' knowledge and attitudes of musculoskeletal pain; development and measurement properties of a new questionnaire.

BACKGROUND: Healthcare practitioner beliefs influence patients' beliefs and health outcomes in musculoskeletal (MSK) pain. A validated questionnaire based on modern pain neuroscience assessing Knowledge and Attitudes of Pain (KNAP) was unavailable. OBJECTIVES: The aim of this study was to develop and test measurement properties of KNAP. DESIGN: Phase 1; Development of KNAP reflecting modern pain neuroscience and expert opinion. Phase 2; a cross-sectional and longitudinal study among Dutch physiotherapy students. METHOD: In the cross-sectional study (n = 424), internal consistency, structural validity, hypotheses testing, and Rasch analysis were examined. Longitudinal designs were applied to analyse test-retest reliability (n = 156), responsiveness, and interpretability (n = 76). RESULTS: A 30-item KNAP was developed in 4 stages. Test-retest reliability: ICC (2,1) 0.80. Internal consistency: Cronbach's α 0.80. Smallest Detectable Difference 90%: 4.99 (4.31; 5.75). Structural validity: exploratory factor analysis showed 2 factors. Hypotheses testing: associations with the Pain Attitudes and Beliefs Scale for Physiotherapists biopsychosocial subscale r = 0.60, with biomedical subscale r = -0.58, with the Neurophysiology of Pain Questionnaire r = 0.52. Responsiveness: 93% improved on KNAP after studying pain education. Minimal Important Change: 4.84 (95%CI: 2.77; 6.91). CONCLUSIONS: The KNAP has adequate measurement properties. This new questionnaire could be useful to evaluate physiotherapy students' knowledge and attitudes of modern pain neuroscience that could help to create awareness and evaluate physiotherapy education programs, and ultimately provide better pain management.

Novel ultrasonographic Halo Score for giant cell arteritis: assessment of diagnostic accuracy and association with ocular ischaemia.

OBJECTIVES: Ultrasound of temporal and axillary arteries may reveal vessel wall inflammation in patients with giant cell arteritis (GCA). We developed a ultrasound scoring system to quantify the extent of vascular inflammation and investigated its diagnostic accuracy and association with clinical factors in GCA. METHODS: This is a prospective study including 89 patients suspected of having GCA, of whom 58 had a confirmed clinical diagnosis of GCA after 6 months follow-up. All patients underwent bilateral ultrasound examination of the three temporal artery (TA) segments and axillary arteries, prior to TA biopsy. The extent of vascular inflammation was quantified by (1) counting the number of TA segments and axillary arteries with a halo and (2) calculating a composite Halo Score that also incorporated the thickness of each halo. RESULTS: Halo counts and Halo Scores showed moderate diagnostic accuracy for a clinical diagnosis of GCA. They correlated positively with systemic inflammation. When compared with the halo count, the Halo Score correlated better with C-reactive protein (CRP) levels and allowed to firmly establish the diagnosis of GCA in more patients. Higher halo counts and Halo Scores were associated with a higher risk of ocular ischaemia. They allowed to identify subgroups of patients with low risk (≤5%) and high risk of ocular ischaemia (>30%). CONCLUSIONS: Ultrasound halo scoring allows to quantify the extent of vascular inflammation in GCA. Extensive vascular inflammation on ultrasound may provide strong diagnostic confirmation and associates with ocular ischaemia in GCA.

Between the Lines: A Qualitative Phenomenological Analysis of the Therapeutic Alliance in Pediatric Physical Therapy.

Aim: To explore perceptions and preferences of children, parents, and physical therapists regarding the therapeutic alliance in pediatric physical therapy in a rehabilitation setting.Methods: Qualitative phenomenological analysis of interviews with children (n = 10), their parents (n = 10), and physical therapists (n = 10).Results: Three themes were identified: importance of trust in the physical therapist, transparency in sharing information, and negotiation concerning goals and tasks of treatment. Parents considered trust in the therapist's relational skills of greater importance to the therapeutic alliance than the therapist's technical skills. Although the physical therapists showed a strong willingness to meet the needs of children and parents, they seemed unaware of the emotional impact of positional inequality and the differences in roles and tasks of children, parents, and therapists during the treatment.Conclusion: All participants emphasized the importance of the quality of the therapeutic alliance. Nevertheless, positional inequality and differences in roles and tasks appeared to influence negotiation about goals and tasks of treatment. Children and parents are in a dependent relationship with the physical therapist. Physical therapists are challenged to find the right balance between their professional position and input on the one hand, and the emotional needs of child and parents on the other hand.

Reducing ceiling effects in the Working Alliance Inventory-Rehabilitation Dutch Version.

Purpose: To reduce ceiling effects on domain scores (Task, Goal, and Bond) of the Working Alliance Inventory (WAI)-Rehabilitation Dutch Version by changing response scales and using Visual Analogue Scales (VASs).Methods: Clients, who had at least three treatment sessions prior, randomly received one of the three versions of the WAI-Rehabilitation Dutch Version, using items with a balanced Likert scale, Positive-Packed Likert scale or VAS. Primary outcome was percentage of ceiling effects in total- and domain scores, secondary outcomes were construct validity and internal consistency of the three versions.Results: One hundred and seventy-six clients randomly received a set of questionnaires (one of the three versions of the WAI-Rehabilitation Dutch Version, Session Rating Scale (SRS) and Helping Alliance Questionnaire (HAQ)-II); 152 participants (mean age 51.5 ± 16.3, 106 women) returned the questionnaires. No ceiling effects were present in the total scores of all versions. Significantly fewer ceiling effects were found in the VAS-Version (Goal: 8.0%, Bond: 7.7%) compared to the original (Goal: 18.0%, Bond: 29.8%) and Positive-Packed Version (Goal: 27.1%, Bond: 29.8%). Spearman's correlations between VAS-Version, SRS and HAQ-II ranged 0.747-0.845.Conclusions: Visual Analogue Scales effectively reduced ceiling effects on domain scores of the WAI-Rehabilitation Dutch Version, while maintaining validity.Implications for RehabilitationVisual Analogue Scales effectively reduced ceiling effects on domain scores of the Working Alliance Inventory-Rehabilitation Dutch Version, while maintaining construct validity.The Working Alliance Inventory version with Visual Analogue Scales can be used in rehabilitation.

Development and validation of the Working Alliance Inventory Dutch version for use in rehabilitation setting.

Background: In rehabilitation, therapeutic alliance is associated with improvements in clinical outcomes. The Working Alliance Inventory (WAI) measures therapeutic alliance and is frequently used in rehabilitation research; however, it has not been validated for rehabilitation. Objectives: To determine content validity, internal consistency and construct validity of the Working Alliance Inventory Rehabilitation Dutch Version (WAI-ReD). Methods: In phase 1, content and face validity of the WAI-ReD was judged by professionals (n = 15) and in phase 2 by patients (n = 22). In phase 3, 14 hypotheses were tested in patients (n = 138) regarding: content validity (i.e., missing items, floor, and ceiling effects); internal consistency; and construct validity (i.e., factor structural testing correlations of WAI-ReD scores with Session Rating Scale (SRS), the Helping Alliance Questionnaire II (HAQ-II), and Visual Analog Scale of Pain (VASpain)). Results: After phase 1 and phase 2, the WAI-ReD was formulated and tested. Content validity; missing items were negligible. Ceiling effects were present in all domains. Internal consistency; Cronbach's α ranged between 0.804 and 0.927. Construct validity; correlations between WAI-ReD, SRS, HAQ-II, and VASpain fell within the hypothesized ranges. Conclusion: Eleven of the 14 hypotheses were not rejected confirming good clinimetric properties of the WAI-ReD. The WAI-ReD can be used in rehabilitation to measure therapeutic alliance.
