Purpose The purpose of this paper is to conceptualise and provide a future research agenda for (in)congruence regarding cues between products, brands and atmospheres. Design/methodology/approach A semi-systematic literature review was conducted. The aim was to assess, critique and synthesise (in)congruence, which was found in the literature to be dispersed and interdisciplinary, and to propose a theoretical framework in the marketing domain. Findings Firstly, the review reveals that sensory and semantic cues are interrelated in products, brands and atmospheres. It illustrates that these cues are the foundation for (in)congruence. Secondly, the findings show various theoretical foundations for (in)congruence. These explain where and how congruence occurs. Lastly, a theoretical framework for (in)congruence and a future research agenda were developed to stimulate further research. Research limitations/implications A theoretical framework was developed to enrich the theoretical knowledge and understanding of (in)congruence in the marketing domain. Practical implications The review reveals that products, brands and atmospheres have spillover effects. Managers are advised to understand the semantic meaning carried by cues to foster various outcomes, to estimate the trade-offs when modifying (in)congruent cues for products, brands and atmospheres. Originality/value The developed theoretical framework advances and deepens the knowledge of (in)congruence in the marketing domain by moving beyond the match and fit between two entities and by revealing the underlying mechanism and its outcomes.

Purpose The purpose of this paper is to develop a comprehensive conceptual framework of visual-tactile interplay and consumer responses in brand, product and servicescape contexts. Design/methodology/approach This paper performs a literature review of visual-tactile interplay by reviewing prior research in marketing and psychology. Findings The review reveals that visual-tactile interplay provokes various consumer responses depending on whether brands, products or servicescapes are used. The paper develops a comprehensive conceptual framework mapping out visual-tactile interplay and the relationship with consumers’ cognition, emotions and behaviors. Research limitations/implications A conceptual model was developed with a novel view on how visual and tactile cues can together influence consumer responses. Practical implications This paper shows how visual-tactile interplay is successful in brand, product and servicescape contexts and provides practical insight for firms into how to provoke consumers’ cognitive, emotional and behavioral responses. Originality/value This paper contributes to existing literature by developing a conceptual framework and model of visual-tactile interplay and consumer responses by drawing on research in marketing and psychology.

For individuals with recurrent or persistent non-specific low back pain (LBP), exercise and exercise combined with education have been shown to be effective in preventing new episodes or in reducing the impact of the condition. Chiropractors have traditionally used Maintenance Care (MC), as secondary and tertiary prevention strategies. The aim of this trial was to investigate the effectiveness of MC on pain trajectories for patients with recurrent or persistent LBP. This pragmatic, investigator-blinded, two arm randomized controlled trial included consecutive patients (18-65 years old) with non-specific LBP, who had an early favorable response to chiropractic care. After an initial course of treatment, eligible subjects were randomized to either MC or control (symptom-guided treatment). The primary outcome was total number of days with bothersome LBP during 52 weeks collected weekly with text-messages (SMS) and estimated by a GEE model. Three hundred and twenty-eight subjects were randomly allocated to one of the two treatment groups. MC resulted in a reduction in the total number of days per week with bothersome LBP compared with symptom-guided treatment. During the 12 month study period, the MC group (n = 163, 3 dropouts) reported 12.8 (95% CI = 10.1, 15.5; p = <0.001) fewer days in total with bothersome LBP compared to the control group (n = 158, 4 dropouts) and received 1.7 (95% CI = 1.8, 2.1; p = <0.001) more treatments. Numbers presented are means. No serious adverse events were recorded. MC was more effective than symptom-guided treatment in reducing the total number of days over 52 weeks with bothersome non-specific LBP but it resulted in a higher number of treatments. For selected patients with recurrent or persistent non-specific LBP who respond well to an initial course of chiropractic care, MC should be considered an option for tertiary prevention.

Background Problem-solving interventions with workplace involvement (PSI-WPI) have been shown to reduce sick leave and increase return to work in an occupational health services context. However, many employees struggle with reduced work functioning, anxiety-, and depressive symptoms up to 12 months after a sick leave episode, and it is unclear if the intervention affects outcomes other than sick leave. The aim of this study is to investigate if a PSI-WPI added to care as usual (CAU) is superior to CAU with respect to self-reported sick leave, psychological symptoms, work ability, work performance, and health after RTW when provided in primary care. Methods Employed individuals aged 18–59 years on sick leave (2 to 12 weeks) diagnosed by a physician at a primary care center with mild to moderate depression, anxiety, or adjustment disorder were enrolled in a two-armed cluster-randomised trial evaluating the effectiveness of a PSI-WPI. Multiple outcomes were recorded at baseline, six months, 12 months, and every fourth week during the study period. Outcomes were categorised into psychological symptoms, health, work ability, work performance, and self-reported sick leave. Data were analysed using MANOVA, GEE (Generalized Estimating Equations), and cox regression. Results One hundred ninety-nine individuals responded to the invitation to participate; one participant withdrew, one was excluded as the employment ended, nine did not answer the baseline survey, and three were removed from the analysis due to missing data. The analysis included 81 subjects who received the intervention and 104 subjects who received the control. Baseline characteristics were similar across both groups. No differences between the groups were found among either variables except one. There was a significant difference between the groups in self-rated health (EQ5D) in favour of the CAU group from baseline to six-month follow-up, with a mean difference of -8.44 (-14.84, -2.04). Conclusions A problem-solving intervention with workplace involvement added to CAU did not result in statistically significant reductions in outcomes. Further research is needed to understand why problem-solving interventions appear to have an effect on sick leave in an occupational health services context and not in a primary care context.

Background In Sweden, almost 60% of patients seeking care at primary healthcare centers do so due to musculoskeletal disorders. These patients constitute a strain on the healthcare system. Manual therapists are experts in diagnosing patients with these conditions but are usually not part of healthcare centers in Sweden. Further, there is a significant societal problem with overuse of medications, injections, medical imaging, and unnecessary surgeries, so-called low-value care, for back and neck pain. We aimed to explore the current management of patients with back and neck pain in primary healthcare centers, staff’s perceptions regarding the need for improvement, and incentives and concerns about having licensed chiropractors and naprapaths (manual therapists) triage these patients as part of the primary healthcare center team. Methods In this qualitative study, we conducted semi-structured focus group interviews with 20 participants employed at three primary healthcare centers in the Stockholm region, chosen based on location, organization, and exposure to manual therapists. Participants were purposefully selected from different professions. Data were analyzed using inductive qualitative manifest and latent content analysis. Results The current management of patients with back and neck pain was described in terms of long waiting times and patients’ expectations of seeing a medical doctor and receiving imaging. Thus, there was room for improvement by reducing low-value care. Participants had limited knowledge about the competence of chiropractors and naprapaths and were concerned about the boundaries of professional identity. Decreased physician workload and more choices for patients were mentioned as incentives for manual therapists to take on a triaging role. Conclusions Staff at three primary healthcare centers in the Stockholm area described the current management of patients with back and neck pain as navigating the expectations of patients and their overreliance on seeing their physician, not other caregivers, resulting in long waiting times. Alongside patients expecting imaging, these were incentives for chiropractors and naprapaths triaging these patients as an opportunity to improve care. A lack of knowledge about the competence of manual therapists was a concern, and assigning manual therapists to the primary healthcare team would necessitate a reconfiguration of the care process, potentially challenging the boundaries of professional identity.

Background Spinal pain is a highly prevalent condition affecting a large part of the population. Chiropractic maintenance care (MC) is a management strategy intended to prevent spinal pain recurrent episodes and deterioration by treating patients at pre-planned intervals. A previous study showed that patients identified as a dysfunctional subgroup by the West Haven-Yale Multidimensional Pain Inventory (MPI) and receiving MC had fewer days with bothersome LBP. This suggests MC may have superior effectiveness in this subgroup of patients. The MPI, however, is not practical for daily clinical practice, prompting the development of the MAINTAIN instrument. This study aims to (1) assess the effectiveness and cost-effectiveness of stratified MC using the MAINTAIN instrument, and (2) assess the fidelity and procedure compliance of implementing the MAINTAIN instrument. Methods This pragmatic randomized clinical trial will recruit 225 consecutive patients (18–65 years old) with significant (> 30 days in the past 12 months) recurrent spinal pain presenting to chiropractic clinics. After the initial 3 weeks (6 visits) of chiropractic care, patients will be randomized to receive either Stratified MC or Standard Chiropractic Care. Stratified MC: patients will complete the MAINTAIN instrument and be stratified to MC or symptom-guided care (clinicians’ judgment). Patients in the Standard Chiropractic Care arm will receive standard treatment based on the chiropractor’s judgment. The primary outcome is the total number of days with activity-limiting pain measured at 12 months. Secondary outcomes include the number of missed working days and loss of work productivity due to pain, pain intensity, disability, health-related quality of life, perceived improvement, and implementation of MAINTAIN instrument outcomes. An intention-to-treat protocol and generalized estimating equations (GEE) linear regression models will be used for analysis. Discussion This study investigates the impact of using a clinical instrument to identify patients with recurrent spinal pain to target those who benefit most from a chiropractic MC approach. Strict inclusion criteria should ensure a suitable target group, and frequently collected repeated measures should provide accurate outcome assessment. The study is pragmatic and includes standard clinical procedures facilitating the generalizability and transferability of the results into clinical practice.

Background Recurrent or persistent neck pain affects a vast number of people globally, leading to reduced quality of life and high societal costs. Clinically, it is a difficult condition to manage, and treatment effect sizes are often moderate at best. Activity and manual therapy are first-line treatment options in current guidelines. We aimed to investigate the combination of home stretching exercises and spinal manipulative therapy in a multicentre randomized controlled clinical trial, carried out in multidiscipline ary primary care clinics. Methods The treatment modalities utilized were spinal manipulative therapy and home stretching exercises compared to home stretching exercises alone. Both groups received 4 treatments for 2 weeks. The primary outcome was pain, where the subjective pain experience was investigated by assessing pain intensity (NRS − 11) and the quality of pain (McGill Pain Questionnaire). Neck disability and health status were secondary outcomes, measured using the Neck Disability Indexthe EQ-5D, respectively. One hundred thirty-one adult subjects were randomized to one of the two treatment groups. All subjects had experienced persistent or recurrent neck pain the previous 6 months and were blinded to the other group intervention. The clinicians provided treatment for subjects in both group and could not be blinded. The researchers collecting data were blinded to treatment allocation, as was the statistician performing data analyses. An intention-to-treat analysis was used. Results Sixty-six subjects were randomized to the intervention group, and sixty-five to the control group. For NRS − 11, a B-coefficient of − 0,01 was seen, indication a 0,01 improvement for the intervention group in relation to the control group at each time point with a p -value of 0,305. There were no statistically significant differences between groups for any of the outcome measures. Conclusion Based on the current findings, there is no additional treatment effect from adding spinal manipulative therapy to neck stretching exercises over 2 weeks for patients with persistent or recurrent neck pain.

Background Manual therapy and exercise are recommended for patients with neck pain. In a recent randomized controlled trial, home stretching exercises with or without manual therapy were offered to subjects with persistent or recurrent neck pain. No difference in pain or disability between the treatment groups were found after the two-week intervention period. We aimed to investigate whether these patients had a better outcome after individual tailoring of the treatment content two months after the initial structured intervention period. Methods This manuscript is a secondary analysis of a previous clinical trial where 131 patients with persistent or recurrent neck pain received treatments over two weeks (the intervention period). Pain and disability were assessed for two months following the intervention period. During this period, the treating therapists could recommend further individualized tailored treatment, including any treatment modality, regardless of the intervention group and whether the participants responded to the intervention (responders) or not (non-responders). Responders from the intervention period were defined as reporting a minimal clinical improvement on the numeric rating scale (NRS-11) at a 20-percentage points improvement (2 increments), regardless of group belonging in the original trial. All other participants were considered non-responders. We also evaluated the number of treatments, differences in disability, quality and affective component of pain, and quality of life during the individualized care period. Results For responders to a randomized trial of manual therapy and stretching exercises, a significant worsening in pain was associated with an increasing number of treatments during a two-month individualized care period. Among non-responders to the initial intervention period, improvement in neck pain disability was observed with individually tailored treatments. Conclusions For responders to a randomized trial of manual therapy and stretching, worsening pain in the individualized care period was associated with increasing numbers of individually tailored treatments. Among non-responders to the initial intervention period, improvement in neck pain disability was observed with individually tailored treatments.

Chiropractic maintenance care is effective as secondary/tertiary prevention of non-specific low back pain (LBP), but the potential effect moderation by psychological characteristics is unknown. The objective was to investigate whether patients in specific psychological sub-groups had different responses to MC with regard to the total number of days with bothersome pain and the number of treatments. Data from a two-arm randomized pragmatic multicenter trial with a 12-month follow up, designed to investigate the effectiveness of maintenance care, was used. Consecutive patients, 18-65 years of age, with recurrent and persistent LBP seeking chiropractic care with a good effect of the initial treatment were included. Eligible subjects were randomized to either maintenance care (prescheduled care) or to the control intervention, symptom-guided care. The primary outcome of the trial was the total number of days with bothersome LBP collected weekly for 12 months using an automated SMS system. Data used to classify patients according to psychological subgroups defined by the West Haven-Yale Multidimensional Pain Inventory (adaptive copers, interpersonally distressed and dysfunctional) were collected at the screening visit. A total of 252 subjects were analyzed using a generalized estimating equations linear regression framework. Patients in the dysfunctional subgroup who received maintenance care reported fewer days with pain (-30.0; 95% CI: -36.6, -23.4) and equal number of treatments compared to the control intervention. In the adaptive coper subgroup, patients who received maintenance care reported more days with pain (10.7; 95% CI: 4.0, 17.5) and more treatments (3.9; 95% CI: 3.5, 4.2). Patients in the interpersonally distressed subgroup reported equal number of days with pain (-0.3; 95% CI: -8.7, 8.1) and more treatments (1.5; 95% CI: 0.9, 2.1) on maintenance care. Psychological and behavioral characteristics modify the effect of MC and should be considered when recommending long-term preventive management of patients with recurrent and persistent LBP.

Background Persistent or recurrent neck pain is associated with perturbations in the autonomic nervous system balance, and nociceptive stimulation has been seen to influence this balance. However, very few prospective studies have addressed the extent to which changes in pain associate with changes in autonomic cardiac regulation. Therefore, we investigated if changes in pain vary with changes in heart rate variability in a cohort of patients treated for persistent or recurrent neck pain. Method This analysis is based on data from a randomized controlled trial in which participants were given home stretching exercises with or without spinal manipulative therapy for two weeks. As the effectiveness of the intervention (home stretching exercises and spinal manipulative therapy) was found to be equal to the control (home stretching exercises alone), all 127 participants were studied as one cohort in this analysis. During the intervention, pain levels were recorded using daily text messages, and heart rate variability was measured in the clinics three times over two weeks. Two approaches were used to classify patients based on changes in pain intensity: 1) Clinically important changes in pain were categorized as either \"improved\" or \"not improved\" and, 2) Pain development was measured using pain trajectories, constructed in a data driven approach. The association of pain categories and trajectories with changes in heart rate variability indices over time were then analysed using linear mixed models. Results Heart rate variability did not differ significantly between improved and not-improved patients, nor were there any associations with the different pain trajectories. Conclusions In conclusion, changes in pain after home stretching exercises with or without spinal manipulative therapy over two weeks were not significantly associated with changes in heart rate variability for patients with persistent or recurrent neck pain. Future studies should rely on more frequent measurements of HRV during longer treatment periods. Trial registration The trial was registered at ClinicalTrials.gov, registration number: NCT03576846.
