Background: Patient-specific and condition-specific measures are widely used in clinical practice and research to measure disability or change over time. While condition-specific outcome measures comprise a range of restrictions generally relevant for all patients, the Patient-Specific Functional Scale measures restrictions chosen by the individual patient. Objectives: Based on the hypothesis that patient-specific and conditionspecific scales deliver comparable results when used on group level. The aim of this study was to test for floor and ceiling effects, to evaluate construct validity and validity to change of the Patient-Specific Functional Scale when compared to condition-specific outcome measures. For this purpose, two datasets from patients with shoulder pain and low back pain were analyzed. Methods: Patient-Specific Functional Scale scores were compared to the Shoulder Pain and Disability Index and the Roland Morris Disability Questionnaire at 4 time-points using stem-and-leaf-plots and correlations using Pearson’s r. Hypothesis-driven correlation levels for data interpretation were predefined, with r ≥0.75=high, r ≥0.5=moderate, r ≥0.25=low. Results: Patient-Specific Functional Scale floor effects were comparable to condition-specific outcome measures in both samples. At none of the timepoints did the Patient-Specific Functional Scale correlate with the conditionspecific outcome measures in the expected manner. Conclusion: Hypotheses regarding expected ranges of correlation between the Patient-Specific Functional Scale and the condition-specific outcome measures for construct validity and validity to change were not met. While the use of the Patient-Specific Functional Scale in a clinical context has its advantages, the measure is not recommended for group-level evaluations.

BackgroundThe evidence that exercise intervention is effective for treatment of chronic low back pain comes from trials that are not placebo-controlled.ObjectiveThe purpose of this study was to investigate the efficacy of motor control exercise for people with chronic low back pain.DesignThis was a randomized, placebo-controlled trial.SettingThe study was conducted in an outpatient physical therapy department in Australia.PatientsThe participants were 154 patients with chronic low back pain of more than 12 weeks’ duration.InterventionTwelve sessions of motor control exercise (ie, exercises designed to improve function of specific muscles of the low back region and the control of posture and movement) or placebo (ie, detuned ultrasound therapy and detuned short-wave therapy) were conducted over 8 weeks.MeasurementsPrimary outcomes were pain intensity, activity (measured by the Patient-Specific Functional Scale), and patient's global impression of recovery measured at 2 months. Secondary outcomes were pain; activity (measured by the Patient-Specific Functional Scale); patient's global impression of recovery measured at 6 and 12 months; activity limitation (measured by the Roland-Morris Disability Questionnaire) at 2, 6, and 12 months; and risk of persistent or recurrent pain at 12 months.ResultsThe exercise intervention improved activity and patient's global impression of recovery but did not clearly reduce pain at 2 months. The mean effect of exercise on activity (measured by the Patient-Specific Functional Scale) was 1.1 points (95% confidence interval [CI]=0.3 to 1.8), the mean effect on global impression of recovery was 1.5 points (95% CI=0.4 to 2.5), and the mean effect on pain was 0.9 points (95% CI=−0.01 to 1.8), all measured on 11-point scales. Secondary outcomes also favored motor control exercise.LimitationClinicians could not be blinded to the intervention they provided.ConclusionsMotor control exercise produced short-term improvements in global impression of recovery and activity, but not pain, for people with chronic low back pain. Most of the effects observed in the short term were maintained at the 6- and 12-month follow-ups.

Background/Aims Stabilisation exercises are commonly prescribed for people with persistent low back pain. However, for some patients, it has been hypothesised that stabilisation exercises could draw attention to protecting the core, promote hypervigilance and inhibit volitional movement. The aim of this study was to compare the effectiveness and reported adverse events, in particular fear avoidance, of stabilisation exercises compared with placebo or other treatments offered by physiotherapists on the outcome of disability and activity at 12- and 24-months' follow-up. Methods The following electronic databases were searched: Embase, Medline, AMED, CINAHL, from inception to June 2019. Only randomised controlled trails were included. Study selection, data extraction and appraisal of quality criteria using PEDro, were undertaken by two independent assessors. Results Seven studies (n=1820) were eligible. Of six studies that reported adverse effects in the group receiving stabilisation exercises, four reported none and two reported mild exacerbation of pain locally or elsewhere. Fear avoidance was not investigated in any of the studies. Across the studies, 12 analyses were reported and included seven different comparator groups and three outcome measures: Oswestry Disability Index (n=1), Roland Morris Disability Questionnaire (n=5), Patient Specific Functional Scale (n=4). Two studies included a 24-month follow up in addition to a 12-month follow up. Of the 12 studies, nine reported no significant differences between the effectiveness of stabilisation exercises and comparator groups. Stabilisation exercises were more effective than comparator groups for the following three analyses: compared to manual therapy or education at 12 but not 24 months for the Oswestry Disability Index (15.71, 95% confidence interval 19.3–10.01); compared to placebo for the Patient Specific Functional Scale (1.5, 95% confidence interval 0.7–2.2) but not the Roland Morris Disability Questionnaire; and compared to high load lifting for the Patient Specific Functional Scale (1.8 95% confidence interval 2.8–0.7). Conclusions Stabilisation exercises are safe and equally effective to other treatments, and possibly superior for some outcomes at some time points. No or only mild adverse effects were reported. However, none of the studies measured fear avoidance as an outcome and we recommend this be included in future randomised controlled trials measuring the effectiveness of stabilisation exercises.

BACKGROUND Low back pain (LBP) is one of the most debilitating conditions among older adults. Unfortunately, existing LBP outcome questionnaires are not adapted for specific circumstances related to old age, which may make these measures less than ideal for evaluating LBP in older adults. OBJECTIVE To explore the necessity of developing age-specific outcome measures, crowdsourcing was conducted to solicit opinions from clinicians globally. METHODS Clinicians around the world voted and/or prioritized various LBP outcome indicators for older adults on a pairwise wiki survey website. Seven seed outcome indicators were posted for voting while respondents were encouraged to suggest new indicators for others to vote/prioritize. The website was promoted on the social media of various health care professional organizations. An established algorithm calculated the mean scores of all ideas. A score >50 points means that the idea has >50% probability of beating another randomly presented indicator. RESULTS Within 42 days, 128 respondents from 6 continents cast 2466 votes and proposed 14 ideas. Indicators pertinent to improvements of physical functioning and age-related social functioning scored >50 while self-perceived reduction of LBP scored 32. CONCLUSIONS This is the first crowdsourcing study to address LBP outcome indicators for older adults. The study noted that age-specific outcome indicators should be integrated into future LBP outcome measures for older adults. Future research should solicit opinions from older patients with LBP to develop age-specific back pain outcome measures that suit clinicians and patients alike.

Purpose: This systematic review and meta-analysis identifies, critically appraises, synthesizes, and meta-analyses the reported psychometric properties of the Patient-Specific Functional Scale (PSFS) in patients with low back pain or pathology. Method: The MEDLINE, Embase, PubMed, and Google Scholar databases were searched from their inception to September 2019. We included prospective measurement studies that reported on the psychometric properties (reliability, validity, responsiveness) of the PSFS in people with low back pain or pathology. We followed the COnsensus-based Standards for the selection of health Measurement INstruments 2018 guideline for systematic reviews. We performed both quantitative and qualitative syntheses in which the results were summarized on the basis of the reported measurement properties and study quality. Results: Ten eligible studies were included. The pooled PSFS reliability measure was excellent (intra-class correlation coefficient = 0.89; 95% CI: 0.75, 0.95). Validity measures displayed correlations that ranged from −0.47 to 0.69 when compared with other patient-reported outcome measures (PROMs) or other tests. Eight studies had assessed the responsiveness of the PSFS. Effect sizes reported were large (≥ 0.91). Conclusions: The PSFS is a reliable, valid, and responsive PROM for patients with low back pain or pathology.

ObjectivesEvaluate the outcomes and explore experiences of patients undergoing a residential combined physical and psychological programme (CPPP) for chronic low back pain.DesignA longitudinal observational cohort design, with a parallel qualitative design using semistructured interviews.SettingResidential, multimodal rehabilitation.Participants136 adults (62 male/74 female) referred to the CPPP, 100 (44 male/56 female) of whom completed the programme, during the term of the study. Ten (2 male/8 female) participated in the qualitative evaluation.InterventionA 3-week residential CPPP.Outcome measuresPrimary outcome measures were the STarT Back screening tool score; pain intensity—11-point Numerical Rating Scale; function—Oswestry Disability Index (ODI); health status/quality of life—EQ-5D-5L EuroQol five-Dimension-five level; anxiety—Generalised Anxiety Disorder-7; depression—Patient Health Questionnaire-9. Secondary outcome measures were the Global Subjective Outcome Scale; National Health Service Friends and Family Test;.ResultsAt discharge, 6 and 12 months follow ups, there were improvements from baseline that were greater than minimum clinically important differences in each of the outcomes (with the sole exception of ODI at discharge). At 12 months, the majority of people considered themselves a lot better (57%) and were extremely likely (86%) to recommend the programme to a friend. The qualitative data showed praise for the residential nature of the intervention and the opportunities for interaction with peers and peer support. There were testimonies of improvements in understanding of pain and how to manage it better. Some participants said they had reduced, or stopped, medication they had been taking to manage their pain.ConclusionsParticipants improved, and maintained long term, beyond minimum clinically important differences on a wide range of outcomes. Participants reported an enhanced ability to self-manage their back pain and support for the residential setting.
