Unhelpful Information About Low Back and Neck Pain on Physiotherapist's Websites.

Background: The internet is increasingly used as a primary source of information for patients with musculoskeletal pain. Private physiotherapy practices provide informative content on low back pain (LBP) and neck pain (NP) on their websites, but the extent to which this information is biopsychosocial, guidelines-consistent, and fear-inducing is unknown. The aim of this study was to analyse the information on websites of private physiotherapy practices in the Netherlands about LBP and NP regarding consistency with the guidelines and the biopsychosocial model and to explore the use of fear-inducing language.

Temporal relationships between pain, functioning, and human assumed central sensitization in patients with chronic low back pain; a single-case design.

Background: Interdisciplinary pain rehabilitation (IPR) aims to improve functioning in people with chronic low back pain (CLBP), and is not primary aimed at pain reduction. Many patients however also report a decrease in pain. An explanation could be that IPR results in a decrease in Central Sensitization (CS).

Maximal aerobic capacity is associated with lifting capacity, but not with self-reported functioning measures in patients with primary chronic low back pain: a cross-sectional study.

Objective: Maximal exercise testing is considered the gold standard to assess V̇Omax. However, maximal exercise testing was previously deemed unfeasible and unsafe in chronic low back pain (CLBP) patients. Consequently, most previous studies on aerobic capacity and functioning in patients with CLBP were performed with submaximal testing protocols.

Central sensitization and functioning in patients with chronic low back pain: A cross-sectional and longitudinal study.

Background: Central sensitization (CS) is present in a subgroup of patients with chronic low back pain (CLBP). Studies on the relationship between CS and functioning have limited operationalizations of CS and functioning.

Objective: To determine whether CS was related to functioning in patients with CLBP (cross-sectional); and to determine whether changes in CS were related to changes in functioning (longitudinal).

Results: Initially, participants reported to be satisfied with their healthcare professionals.

Long-term follow-up of patients with chronic musculoskeletal pain attending interdisciplinary pain rehabilitation: outcomes and predictive factors.

The long-term outcomes of interdisciplinary pain rehabilitation (IPR) in patients with chronic musculoskeletal pain (CMP) and its predictors has been studied to a limited extent. In this historical cohort study, functioning, satisfaction with life domains, and pain were assessed at baseline, discharge, and at 6-15 years follow-up. At follow-up, most patients (77%) rated the effects of the IPR as temporarily or persistently positive.

Can We Change Health Care Costs in Patients With Complex Back Pain?: Results From a 5-year Before and After Study.

Study Design: A before and after study cohort study.

Objectives: The aim of this study was to examine changes in health care costs after multidisciplinary spine care in patients with complex chronic back pain (CBP), to analyze the predictive value of patient and disease characteristics on health care costs, and to study the potential impact of biases concerning the use of real world data.

Summary Of Background Data: Due to high direct and indirect societal costs of back pain there is a need for interventions that can assist in reducing the economic burden on patients and society.

Central Sensitisation and functioning in patients with chronic low back pain: protocol for a cross-sectional and cohort study.

Introduction: A relevant subsample of patients with chronic low back pain (CLBP) have manifested augmented central pain processing, central sensitisation (CS). Patients with CLBP have limited functioning and participation. Theoretically, physical functioning in patients with CLBP can plausibly be linked to CS; however, evidence to explain such association is scarce.

Personal and Societal Impact of Low Back Pain: The Groningen Spine Cohort.

Study Design: Cross-sectional study.

Objective: The aim of this study was to study the personal and societal impact of low back pain (LBP) in patients admitted to a multidisciplinary spine center.

Assessing discrepancies in outcomes of pain rehabilitation: "these questionnaires don't measure results that are relevant to me".

Pain rehabilitation programs are recommended interventions for patients with chronic pain. Average effect sizes are moderate. Physiatrists, based on clinical experience, argue that the present outcome measures underestimate the outcome of pain rehabilitation programs.

Dosage of pain rehabilitation programmes for patients with chronic musculoskeletal pain: a non-inferiority randomised controlled trial.

To analyse the effects of interdisciplinary pain rehabilitation programmes with different dosages; care as usual versus short form. A single blinded, two armed, randomised controlled trial, with non-inferiority design was performed. All patients with chronic musculoskeletal pain referred to an outpatient multidisciplinary pain rehabilitation programme were eligible for this study.

Cut-Off Points for Mild, Moderate, and Severe Pain on the Numeric Rating Scale for Pain in Patients with Chronic Musculoskeletal Pain: Variability and Influence of Sex and Catastrophizing.

The 0-10 Numeric Rating Scale (NRS) is often used in pain management. The aims of our study were to determine the cut-off points for mild, moderate, and severe pain in terms of pain-related interference with functioning in patients with chronic musculoskeletal pain, to measure the variability of the optimal cut-off points, and to determine the influence of patients' catastrophizing and their sex on these cut-off points. 2854 patients were included.

Case complexity in patients with chronic nonspecific musculoskeletal pain: a Delphi and feasibility study.

Assessment of case complexity in patients with chronic nonspecific musculoskeletal pain (CMP) is currently clinician based, not transparent, and with low reliability. The objective of this study was to explore case complexity and to initiate the development of a case complexity index (CCI). A three-round Delphi study among clinicians involved in multidisciplinary Pain Rehabilitation Programs was performed to identify important factors that are assumed to influence functioning in patients with CMP.
