- PURPOSE: Patient satisfaction is an outcome measure for low-back pain (LBP) interventions which allows clinicians to design patient-oriented treatments. The Treatment Outcome Satisfaction Questionnaire (TOSQ) is an English instrument constructed for such evaluations, and no equivalent instruments exist for the Swedish population. This study, therefore, translated TOSQ into Swedish and assessed the translated version's psychometric properties for patients with LBP.METHODS: A cross-cultural adaptation was used to translate TOSQ into Swedish. Subsequently, data from 131 patients with LBP whom undergone physiotherapy were consecutively aggregated and analyzed in a Rasch rating scale model with person measures standardized at 0-100 logits to evaluate the translated scale's validity. Finally, test-retest reliability of the Swedish version of TOSQ (TOSQ-S) was quantified via an intraclass correlation coefficient (ICC) and the standard error of measurement (SEM) in 41 patients.RESULTS: TOSQ was successfully translated into Swedish; however, while some Rasch model indices supported the translated scale's unidimensionality, one out of eight items and 12 out of 131 subjects misfitted the model. Scale optimization resulted in a 6-item subconfiguration, for which all items fitted the model, person misfits were reduced to ten subjects, and the person separation index increased from 1.86 to 2.04. ICC and SEM estimates suggested acceptable reliability for the six-item TOSQ-S at 0.66 and 6.6 logits, respectively.CONCLUSIONS: A six-item TOSQ-S configuration showed acceptable psychometric properties and is suitable for measuring treatment outcome satisfaction of physiotherapy in patients with LBP.

- Objective: The aim of this study was to determine whether job strain, i.e. a combination of job demands and decision latitude (job control), and sleep disturbances among persons with occasional low-back pain are prognostic factors for developing troublesome low-back pain; and to determine whether sleep disturbances modify the potential association between job strain and troublesome low-back pain. Methods: A population-based cohort from the Stockholm Public Health Cohort surveys in 2006 and 2010 (n = 25,167) included individuals with occasional low-back pain at baseline 2006 (n = 6,413). Through logistic regression analyses, potential prognostic effects of job strain and sleep disturbances were studied. Stratified analyses were performed to assess modification of sleep disturbances on the potential association between job strain and troublesome low-back pain. Results: Those exposed to job strain; active job (odds ratio (OR) 1.3, 95% confidence interval (95% CI) 1.1-1.6), or high strain (OR 1.5, 95% CI 0.9-2.4) and those exposed to severe sleep disturbances (OR 3.0, 95% CI 2.3-4.0), but not those exposed to passive jobs (OR 1.1, 95% CI 0.9-1.4) had higher odds of developing troublesome low-back pain. Sleep disturbances did not modify the association between job strain and troublesome low-back pain. Conclusion: These findings indicate that active job, high job strain and sleep disturbances are prognostic factors for troublesome low-back pain. The odds of developing troublesome low-back pain due to job strain were not modified by sleep disturbance.

- Background: In chronic fatigue syndrome/myalgic encephalomyelitis (ME/CFS), the capacity for activity and participation is strongly limited. The disease definition is very broad, and considering the lack of evidence for best treatment, it is important to understand what is ME/CFS-specific in the biopsychosocial perspective in comparison with similar syndromes. The objective was to study the difference between those diagnosed with ME/CFS and those with similar symptoms but no ME/CFS diagnosis for self-perceived level of physical activity, work ability, anxiety/depression, and health-related quality of life. Methods: This was a clinical cross-sectional study with data collected from mailed questionnaires. The following variables were compared between patients diagnosed with ME/CFS (n = 205) and those with similar symptoms but no diagnosis (n = 57); level of physical activity, Work ability index (WAI), Hospital anxiety and depression scale (HAD-A/HAD-D), and RAND-36 Physical functioning, Role limitations due to physical health problems, Role limitations due to personal or emotional problems, Social functioning, Energy/fatigue, Bodily pain, Emotional well-being, and General health perceptions. The Chi-squared test (nominal data), the Mann-Whitney U test, the Student’s t test and regression analysis were used to analyze the data. Results: The group diagnosed with ME/CFS had a more impaired physical and mental exertion ability as compared to the group that had similar symptoms but was not diagnosed with ME/CFS, shown by a RAND-36 lower index of physical role functioning, social functioning, energy, worse pain and poorer overall health (p ≤ 0.05). In contrast, no significant group differences emerged for weekly level of physical activity, work ability, anxiety/depression, and RAND-36 Emotional role limitation and well-being. Conclusion: Our results indicate that those with a diagnosis of ME/CFS are characterized by an impaired ability for physical or mental exertion, worse pain, and poorer overall health as compared to individuals with similar symptoms but for whom ME/CFS-diagnosis was not established. The results may be cautiously interpreted as support when focusing on patients’ self-care in terms of management of energy levels. The results must however be verified in future studies.

- Low back pain (LBP) varies over time. Consumers, clinicians, and researchers use various terms to describe LBP fluctuations, such as episodes, recurrences and flares. Although "flare" is use commonly, there is no consensus on how it is defined. This study aimed to obtain consensus for a LBP flare definition using a mixed-method approach. Step 1 involved the derivation of a preliminary candidate flare definition based on thematic analysis of views of 130 consumers in consultation with an expert consumer writer. In step 2, a workshop was conducted to incorporate perspectives of 19 LBP experts into the preliminary flare definition, which resulted in 2 alternative LBP flare definitions. Step 3 refined the definition using a 2-round Delphi consensus with 50 experts in musculoskeletal conditions. The definition favored by experts was further tested with 16 individuals with LBP in step 4, using the definition in three scenarios. This multiphase study produced a definition of LBP flare that distinguishes it from other LBP fluctuations, represents consumers views, involves expert consensus, and is understandable by consumers in clinical and research contexts: "A flare-up is a worsening of your condition that lasts from hours to weeks that is difficult to tolerate and generally impacts your usual activities and/or emotions." Perspective: A multiphase process, incorporating consumers views and expert consensus, produced a definition of LBP flare that distinguishes it from other LBP fluctuations.

Best Practice Physiotherapy for Patients with Low Back Pain in Primary Care : Clinical Outcomes and Explanatory Factors
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Clinical practice guidelines provide general recommendations informing best practice physiotherapy for low back pain (LBP). Despite increased research on LBP, the recommendations have barely changed over the last few decades and the burden of LBP remains. New research strategies have been suggested to further understand the complexity of factors influencing recovery of LBP. Several mechanisms are expected to underpin the benefits of physiotherapy care. How different factors influence and explain treatment outcome in patients in different phases of primary care pathway needs to be better understood for the development of better targeted LBP interventions.The overall aim of this thesis was to investigate if and how best practice physiotherapy primary care for patients with LBP can improve clinical outcome.Methods: The four papers in the thesis are based on two randomised controlled trials (RCT) evaluating best practice physiotherapy for patients with LBP in different phases of the primary care pathway reflecting the variation of patients’ needs. Two papers investigated pre-surgery physiotherapy compared to being on a waiting-list in patients with degenerative lumbar spine disorders who are surgical candidates (n = 197). Effects on walking ability and quadriceps femoris strength were evaluated. Associations between the pre-surgery physical factors with 1-year post-surgery physical activity (PA) level were analysed using multiple linear regression. The dose-response relationship was investigated comparing the effects of attending ≤11 treatment sessions with ≥12 treatment sessions. Multiple mediation analyses and conditional process analyses were used to explore physical and psychosocial factors as mediators and patients’ treatment expectations as a moderator of the treatment’s effects on disability, back pain intensity, health-related quality of life (HRQoL), and self-rated health.Two papers were based on a stepped cluster RCT, where a physiotherapy primary healthcare model for LBP (the BetterBack MoC) was regionally implemented. Patients seeking care for LBP were allocated to either the BetterBack MoC (after implementation) or to routine care (before implementation) (n = 467). In a prospective cohort study within the RCT, the associations between patients’ initial illness perceptions and outcomes in disability, back pain intensity, HRQoL, and self-care enablement (i.e., perceived ability to understand and cope with LBP) after 3 and 12 months were explored using stepwise linear regression. Single mediation analyses were used to test whether a priori hypothesised patients’ illness perceptions and self-care enablement at 3 months mediated effects in disability and pain at 6 months of care according to the BetterBack MoC compared to routine care. Exploratory mediation analyses were also used to compare guideline-adherent care with non-adherent care. Guideline-adherent care was defined as care that included education and exercise interventions and did not include non-evidence-based interventions, referral to specialist care, or imaging.Results: Small positive effects from pre-surgery physiotherapy were seen in walking ability and quadriceps femoris strength. No clear dose-response relationship could be demonstrated when comparing the effects of ≤11 treatment sessions with ≥12. Pre-surgery physical outcome measures together explained 27.5% of the variation in PA level 1-year post-surgery, mainly explained by the pre-surgery PA level. The effect of the pre-surgery physiotherapy on patients’ PA level partly explained the treatment’s effect on self-rated health. Furthermore, among biopsychosocial factors, self-efficacy related to activities of daily living (ADL) partly explained the effect on all outcomes. PA related fear avoidance beliefs partly explained the effects on pain and self-rated health. Patients’ treatment expectations moderated the effect in all outcomes. High expectations had a positive moderating effect, while expectation of full recovery had a suppressive effect. In patients seeking physiotherapy for LBP, negative initial prognosis and treatment expectations were associated with worse scores in several outcomes at 3- and 12-month follow-ups. Patients’ illness perceptions and self-care enablement did not explain the effects of care after implementing the BetterBack MoC. This was mainly due to the BetterBack MoC not having superior effects over routine care on the hypothesised mediators. Illness perceptions and self-care enablement at 3 months were associated with disability and pain at 6 months. Further, these factors partly explained the effects of guideline-adherent care in disability and pain.Conclusions: Patients’ illness perceptions, self-care enablement, ADL self-efficacy, and PA related fear-avoidance beliefs were supported to be potential factors explaining the effect on clinical outcomes of best practice physiotherapy for LBP in primary care. Patients’ initial expectations regarding the prognosis and treatment may influence prospective outcomes including patients’ self-care enablement. More specifically, pain and disability outcomes of best practice physiotherapy for patients seeking care for LBP may improve by targeting patients’ illness perceptions and self-care enablement. Patients who are surgical candidates can increase their physical capacity and walking related performance through best practice physiotherapy. In this pre-surgery phase, the treatment should include targeting patients’ ADL self-efficacy, PA related fear-avoidance beliefs, and PA level for improved disability, pain, and HRQoL.

- This study evaluated inter- and intra-observer reliability and discriminative validity of three movement control tests: 1) standing knee-lift test; 2) static lunge test; and 3) dynamic lunge test. Thirty-eight subjects, 21 with low-back pain and 17 healthy, were video-recorded while performing the tests. Four physical therapists scored the tests according to a standardized protocol and calculated a composite score for each test based on the number of incorrect test components. Inter-observer reliability for the composite scores ranged between 0.68 and 0.80 (ICC 2,k) and intra-observer reliability between 0.54 and0.82 (ICC 2,1). The separate test components ranged between 0.32 and 0.91 (κfree) for inter-observer reliability and 0.42 and1.00 for intra-observer reliability. Test components showing the highest values were: back extension; arm lowering; and shoulders moving backwards. Components hip hitch, trunk lateral flexion, knee not lifted straight up and hips moving backwards did not reach accepted thresholds. Discriminative validity ranged between 0.47 and 0.56 (AUC). As our results showed an overall good agreement for the composite, scores and for the majority of the included test components the tests can be considered reliable enough. As the tests' discriminative ability was close to "none", they should, however, not be used for diagnostic purposes but should be further evaluated toward predicted validity.

- BACKGROUND: Clinical examinations are subjective and often show a low validity and reliability. Objective and highly reliable quantitative assessments are available in laboratory settings using 3D motion analysis, but these systems are too expensive to use for simple clinical examinations. Qinematic™ is an interactive movement analyses system based on the Kinect camera and is an easy-to-use clinical measurement system for assessing posture, balance and side-bending. The aim of the study was to test the test-retest the reliability and construct validity of Qinematic™ in a healthy population, and to calculate the minimal clinical differences for the variables of interest. A further aim was to identify the discriminative validity of Qinematic™ in people with low-back pain (LBP).METHODS: We performed a test-retest reliability study (n = 37) with around 1 week between the occasions, a construct validity study (n = 30) in which Qinematic™ was tested against a 3D motion capture system, and a discriminative validity study, in which a group of people with LBP (n = 20) was compared to healthy controls (n = 17). We tested a large range of psychometric properties of 18 variables in three sections: posture (head and pelvic position, weight distribution), balance (sway area and velocity in single- and double-leg stance), and side-bending.RESULTS: The majority of the variables in the posture and balance sections, showed poor/fair reliability (ICC < 0.4) and poor/fair validity (Spearman <0.4), with significant differences between occasions, between Qinematic™ and the 3D-motion capture system. In the clinical study, Qinematic™ did not differ between people with LPB and healthy for these variables. For one variable, side-bending to the left, there was excellent reliability (ICC =0.898), excellent validity (r = 0.943), and Qinematic™ could differentiate between LPB and healthy individuals (p = 0.012).CONCLUSION: This paper shows that a novel software program (Qinematic™) based on the Kinect camera for measuring balance, posture and side-bending has poor psychometric properties, indicating that the variables on balance and posture should not be used for monitoring individual changes over time or in research. Future research on the dynamic tasks of Qinematic™ is warranted.
