Reliability and validity of the back performance scale: observing activity limitation in patients with back pain.

Study Design. A single group design to examine reliability and validity of the Back Performance Scale. Objectives: To examine intertester reliability, test-retest reliability, and concurrent validity of the Back Performance Scale. Summary of Background Data: The Back Performance Scale is a condition-specific performance measure of activity limitation in patients with back pain. It includes five tests of daily activities requiring mobility of the trunk: sock test, pick-up test, roll-up test, fingertip-to-floor test, and lift test. Discriminative ability and responsiveness to important change have previously been demonstrated. Methods. A total of 41 patients with back pain participated in the study. Two physiotherapists examined test performances concurrently, but independently. The patients filled in three questionnaires, two reflecting perceived disability (Der Funktionsfragenbogen Hannover, Roland-Morris Disability Questionnaire) as well as one for fear avoidance of daily activities and work (Fear Avoidance Belief Questionnaire). One physiotherapist retested the patients after 2 to 3 days. Results. Intertester agreement of the Back Performance Scale sum score was very high (intraclass correlation coefficient 2.1): 0.996. Within-patient standard deviation (sw) on the 16-point Back Performance Scale was very low: 0.25. Test-retest reliability was high (intraclass correlation coefficient = 0.91, sw = 1.3). Intertester agreement of the separate tests was also very high, ranging from κ= 0.90–1.00. Test-retest reliability was moderate to high (κ= 0.55–0.83). A high correlation was demonstrated between the Back Performance Scale and the Der Funktionsfragenbogen Hannover: Spearman rho (ρ) = 0.825, P < 0.01. Correlation between the Back Performance Scale and Roland-Morris Disability Questionnaire was moderate: ρ = 0.454, P < 0.01. No correlation was demonstrated between the Back Performance Scale and the Fear Avoidance Belief Questionnaire. Conclusion. The Back Performance Scale appears to be a reliable and valid outcome measure of activity limitation.

Systematic review of active workplace interventions to reduce sickness absence

Background The workplace is used as a setting for interventions to prevent and reduce sickness absence, regardless of the specific medical conditions and diagnoses. Aims To give an overview of the general effectiveness of active workplace interventions aimed at preventing and reducing sickness absence. Methods We systematically searched PubMed, Embase, Psych-info, and ISI web of knowledge on 27 December 2011. Inclusion criteria were (i) participants over 18 years old with an active role in the intervention, (ii) intervention done partly or fully at the workplace or at the initiative of the workplace and (iii) sickness absence reported. Two reviewers independently screened articles, extracted data and assessed risk of bias. A narrative synthesis was used. Results We identified 2036 articles of which, 93 were assessed in full text. Seventeen articles were included (2 with low and 15 with medium risk of bias), with a total of 24 comparisons. Five interventions from four articles significantly reduced sickness absence. We found moderate evidence that graded activity reduced sickness absence and limited evidence that the Sheerbrooke model (a comprehensive multidisciplinary intervention) and cognitive behavioural therapy (CBT) reduced sickness absence. There was moderate evidence that workplace education and physical exercise did not reduce sickness absence. For other interventions, the evidence was insufficient to draw conclusions. Conclusions The review found limited evidence that active workplace interventions were not generally effective in reducing sickness absence, but there was moderate evidence of effect for graded activity and limited evidence for the effectiveness of the Sheerbrooke model and CBT.

Considerations made by the general practitioner when dealing with sick-listing of patients suffering from subjective and composite health complaints

Abstract Objectives. To explore GPs’ considerations in decision-making regarding sick-listing of patients suffering from SHC. Design. Qualitative analysis of data from nine focus-group interviews. Setting. Three cities in different regions of Norway. Participants. A total of 48 GPs (31 men, 17 women; aged 32–65) participated. The GPs were recruited when invited to a course dealing with diagnostic practice and assessment of sickness certificates related to patients with composite SHCs. Results. Decisions on sick-listing patients with SHCs were regarded as a very challenging task. Trust in the patients own story and self-judgement was deemed crucial, but many GPs missed hard evidence of illness and loss of function. Several factors that might influence decision-making were identified: the patients’ ability to present their story to evoke sympathy, the GPs prior knowledge of the patient, and the GPs’ own experience as a patient and their tendency to avoid conflicts. The approach to the task of sick-listing differed from patient-led cooperation to resistant confrontation. Conclusion and implications. Issuing sickness certification in patients with composite health complaints is considered challenging and burdensome. It is seen as mainly patient-driven, and the decisions vary according to GPs’ attitudes, beliefs, and personalities. Guiding the GPs to a more focused awareness of the decision process should be considered.

Diagnoses of Patients with Severe Subjective Health Complaints in Scandinavia: A Cross Sectional Study

Background. A diagnosis is the basis of medical action, the key to various social privileges and national sick leave statistics. The objectives of this study were to investigate which diagnoses general practitioners in Scandinavia give patients with severe subjective health complaints, and what kind of treatments they suggested. Methods. One hundred and twenty-six self-selected general practitioners in Scandinavia diagnosed nine patients, presented as video vignettes, in a cross-sectional study. The main outcome measures were primary, secondary, and tertiary diagnoses. Results. The nine patients got between 13 and 31 different primary diagnoses and a large variety of secondary and tertiary diagnoses. Fifty-eight percent of the general practitioners chose different primary and secondary diagnoses, indicating that they judged the patients to have multimorbid complaints. The most commonly recommended treatment was referral to a psychologist, a mix of psychological and physical treatments, or treatment by the general practitioner. Conclusion. Scandinavian general practitioners give a large variety of symptom diagnoses, mainly psychological and general and unspecified, to patients with severe subjective health complaints. Referral to a psychologist or a mix of psychological or physical treatments was most commonly suggested to treat the patients.

Barriers against returning to work – as perceived by disability pensioners with back pain: A focus group based qualitative study

Purpose. The aim of this study was to explore the issue of perceived barriers for returning to work, based on the experiences and beliefs in a group of disability pensioners with back pain. Method. Focus groups were used to interview 12 women and five men, aged 38 – 56, who participated in a larger project aiming to help disability pensioners back to work. Results. The barriers appearing were related to earlier negative experiences, poor self-judgement of work ability and low self-esteem, lack of support from social security authorities and unsuitable economic arrangements. The pensioners also suggested alternative solutions for making a possible return to work. Conclusions. Our study provides insight into the perceived barriers of returning to work and might be useful in future efforts aiming to help disability pensioners back to work.

Motivating disability pensioners with back pain to return to work--a randomized controlled trial.

OBJECTIVE To investigate the outcome of a brief vocational-oriented intervention aiming to motivate disability pensioners with back pain to return to work, and to evaluate prognostic factors for having entered a return to work process during the following year. DESIGN A randomized controlled trial was conducted. SUBJECTS Participants (n = 89) (mean age 49 years, 65% women) who had received disability pension for more than one year were randomized into an intervention group (education, reassurance, motivation, vocational counselling, n = 45) and a control group (n = 44). METHODS Primary outcome measures were return to work or having entered a return to work process. Secondary outcome measures were life satisfaction, disability, fear avoidance behaviour and expectancy. RESULTS The intervention had no statistically significant effect on return to work or having entered a return to work process at 1-year follow-up. Twice as many in the intervention group (n = 10, 22%) had entered a return to work process compared with the controls (n = 5, 11%). The number needed to treat was 9.2 (95% confidence interval (CI) = 3.4, Inf). Only minor differences in secondary outcome measures were demonstrated. Positive expectancy, better physical performance and less pain were related to return to work. CONCLUSION The effort of returning disability pensioners to work by a brief vocational-oriented intervention may be of clinical relevance. The effect needs to be explored further in larger samples of disability pensioners.

Responsiveness to Change of 10 Physical Tests Used for Patients With Back Pain

Background Few studies have examined the responsiveness of physical tests. Objective The purpose of this study was to explore the responsiveness of 10 physical tests used for patients with back pain in order to illuminate the significance of changes in scores. Design Cross-sectional and longitudinal designs within a prospective cohort study were applied. Methods Distribution-based and anchor-based methods were used. Ninety-eight patients (18–65 years of age) with long-lasting back pain were recruited consecutively at an outpatient spine clinic. Measurements The participants were assessed using 10 physical tests and 2 questionnaires (Hannover Functional Ability Questionnaire and Roland-Morris Disability Questionnaire) at inclusion and after rehabilitation. Six predefined hypotheses for each test were examined regarding the association between changes in scores on the physical tests and the self-report measures of functioning and regarding the relationship of changes in scores on the physical tests and external anchors of important change. Results Five physical tests demonstrated responsiveness by both distribution-based and anchor-based methods: spondylometry, lateral flexion test, fingertip-to-floor test, lift test, and Back Performance Scale (4 hypotheses confirmed). The minimal important change values were all within the range of the smallest detectable change for individual patients. Responsiveness by distribution-based methods only (3 hypotheses confirmed) was shown for the Biering-Sørensen test and the loaded reach test, whereas little evidence of responsiveness (1 hypothesis confirmed) was shown for the Global Physiotherapy Examination flexibility subscale, the Progressive Isoinertial Lifting Evaluation, and the 15-m (50-ft) walk test. Limitations The smallest detectable change values were examined in a small sample of patients and need further exploration. Conclusions Responsiveness varied among the 10 physical tests.

The Efficacy of Low-Level Laser Therapy for Shoulder Tendinopathy: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND AND PURPOSE Low-level laser therapy (LLLT) is proposed as a treatment for tendinopathies. This is the first systematic review focusing solely on LLLT treatment effects in shoulder tendinopathy. METHODS A systematic review with meta-analysis and primary outcome measures pain relief on 100-mm visual analogue scale (VAS) and relative risk for global improvement. Two independent assessors rated the included studies according to the PEDro scale. Intervention quality assessments were performed of LLLT dosage and treatment procedures according to World Association for Laser Therapy guidelines. The included trials were sub-grouped by intervention quality and use of other physiotherapy interventions. RESULTS Seventeen randomized controlled trials (RCTs) met the inclusion criteria, and 13 RCTs were of high and 4 RCTs of moderate methodological quality. Significant and clinically important pain relief was found with weighted mean differences (WMD) over placebo, for LLLT as monotherapy at 20.41 mm (95% CI: 12.38 to 28.44) and as adjunct to exercise therapy at 16.00 mm (95% CI: 11.88 to 20.12). The WMD when LLLT was used in a multimodal physiotherapy treatment regime reached statistical significance over placebo at 12.80 (95% CI: 1.67-23.94) mm pain reduction on VAS. Relative risks for global improvement were statistically significant at 1.96 (95% CI: 1.25-3.08) and 1.51 (95% CI: 1.12-2.03), for laser as monotherapy or adjunctive in a physiotherapy regime, respectively. Secondary outcome measures of shoulder function were only significantly in favour of LLLT when used as monotherapy. Trials performed with inadequate laser doses were ineffective across all outcome measures. CONCLUSION This review shows that optimal LLLT can offer clinically relevant pain relief and initiate a more rapid course of improvement, both alone and in combination with physiotherapy interventions. Our findings challenge the conclusions in previous multimodal shoulder reviews of physiotherapy and their lack of intervention quality assessments.

Researcher-researched relationship in qualitative research: Shifts in positions and researcher vulnerability

Background The researcher role is highly debated in qualitative research. This article concerns the researcher-researched relationship. Methods A group of health science researchers anchored in various qualitative research traditions gathered in reflective group discussions over a period of two years. Results Efforts to establish an anti-authoritarian relationship between researcher and researched, negotiation of who actually “rules” the research agenda, and experiences of shifts in “inferior” and “superior” knowledge positions emerged as central and intertwined themes throughout the discussions. The dual role as both insider and outsider, characteristic of qualitative approaches, seemed to lead to power relations and researcher vulnerability which manifested in tangible ways. Conclusion Shifting positions and vulnerability surfaced in various ways in the projects. They nonetheless indicated a number of similar experiences which can shed light on the researcher-researched relationship. These issues could benefit from further discussion in the qualitative health research literature.

GPs’ negotiation strategies regarding sick leave for subjective health complaints

Abstract Objectives. To explore general practitioners’ (GPs’) specific negotiation strategies regarding sick-leave issues with patients suffering from subjective health complaints. Design. Focus-group study. Setting. Nine focus-group interviews in three cities in different regions of Norway. Participants. 48 GPs (31 men, 17 women; age 32–65), participating in a course dealing with diagnostic practice and assessment of sickness certificates related to patients with subjective health complaints. Results. The GPs identified some specific strategies that they claimed to apply when dealing with the question of sick leave for patients with subjective health complaints. The first step would be to build an alliance with the patient by complying with the wish for sick leave, and at the same time searching for information to acquire the patients perspective. This position would become the basis for the main goal: motivating the patient for a rapid return to work by pointing out the positive effects of staying at work, making legal and moral arguments, and warning against long-term sick leave. Additional solutions might also be applied, such as involving other stakeholders in this process to provide alternatives to sick leave. Conclusions and implications. GPs seem to have a conscious approach to negotiations of sickness certification, as they report applying specific strategies to limit the duration of sick leave due to subjective health complaints. This give-and-take way of handling sick-leave negotiations has been suggested by others to enhance return to work, and should be further encouraged. However, specific effectiveness of this strategy is yet to be proven, and further investigation into the actual dealings between doctor and patients in these complex encounters is needed.
