Physical Function Following Total Knee Arthroplasty for Osteoarthritis: A Longitudinal Systematic Review With Meta-analysis.

To explore the extent of functional improvement following primary total knee arthroplasty for knee osteoarthritis and to compare the trajectories of self-reported and performance-based measures of physical function. Longitudinal systematic review with meta-analysis We searched 3 electronic databases from January 2005 to February 2023 for longitudinal cohort studies involving adults with knee osteoarthritis undergoing primary total knee arthroplasty. Estimates of self-reported and performance-based physical function were extracted presurgery and up to 5 years postsurgery.

Why might fears and worries persist after a pain education-grounded multimodal intervention for chronic back pain? A qualitative study.

Introduction: The effect of pain education (PE) on pain intensity and function diminishes after a few months in people with chronic low back pain (CLBP). One possible explanation is the return of underlying fears and worries related to the condition.

Objective: To explore topics related to participants' beliefs and feelings that might explain why fears and worries persist after a PE-grounded intervention for CLBP.

Body image at the trunk: An investigation into externally referenced width perception and picture mapping.

Body image is a conscious representation of the body, encompassing how our body feels to us. Body image can be measured in a variety of ways, including metric and depictive measures. This study sought to assess body image at the trunk by investigating, and comparing, a metric and depictive measure.

The characteristics of the implicit body model of the trunk.

Knowing where the body is in space requires reference to a stored model of the size and shape of body parts, termed the body model. This study sought to investigate the characteristics of the implicit body model of the trunk by assessing the position sense of midline and lateral body landmarks. Sixty-nine healthy participants localised midline and lateral body landmarks on their thorax, waist and hips, with perceived positions of these landmarks compared to actual positions.

It's OK to Move! Effect of a Brief Video on Community Confidence in Activity Despite Back Pain: A Randomized Trial.

To estimate the difference in confidence to become active despite low back pain in people who were exposed to one of 2 video interventions delivered on social media, compared to no intervention. A proof-of-concept, 3-group randomized controlled trial, in a 1:1:1 ratio. Participants aged 18 years and over, with and without low back pain, were recruited via the social media channel Facebook, to view either a humorous video, a neutral video, or to no intervention.

The Fremantle Back Awareness Questionnaire: cross-cultural adaptation, reliability, and validity of the Italian version in people with chronic low back pain.

Background And Aim: There is evidence to suggest that assessing back-specific altered self-perception may be useful when seeking to understand and manage low back pain (LBP). The Fremantle Back Awareness Questionnaire (FreBAQ) is a patient-reported measure of back-specific body perception that has never been adapted and psychometrically analysed in Italian. Hence, the objectives of this research were to cross-culturally adapt and validate the Italian version of this outcome measure (namely, the FreBAQ-I), to make it available for use with Italians suffering from chronic LBP.

Tactile localization accuracy at the low back.

Localizing tactile stimulation is an important capability for everyday function and may be impaired in people with persistent pain. This study sought to provide a detailed description of lumbar spine tactile localization accuracy in healthy individuals. Sixty-nine healthy participants estimated where they were touched at nine different points, labelled in a 3 × 3 grid over the lumbar spine.

Mechanisms of education and graded sensorimotor retraining in people with chronic low back pain: a mediation analysis.

An improved understanding of the biopsychosocial influences that contribute to and maintain pain has promoted the development of new efficacious treatments for chronic low back pain (CLBP). This study aimed to investigate the mechanisms of a new treatment-education and graded sensorimotor retraining-on pain and disability. We conducted a preplanned causal mediation analysis of a randomized clinical trial which allocated 276 participants with CLBP to 12 weekly clinical sessions of education and graded sensorimotor retraining (n = 138) or a sham and attention control (n = 138).

Interventions for treating pain and disability in adults with complex regional pain syndrome- an overview of systematic reviews.

Background: Complex regional pain syndrome (CRPS) is a chronic pain condition that usually occurs in a limb following trauma or surgery. It is characterised by persisting pain that is disproportionate in magnitude or duration to the typical course of pain after similar injury. There is currently no consensus regarding the optimal management of CRPS, although a broad range of interventions have been described and are commonly used.

Pharmacological treatments for low back pain in adults: an overview of Cochrane Reviews.

Background: Pharmacological interventions are the most used treatment for low back pain (LBP). Use of evidence from systematic reviews of the effects of pharmacological interventions for LBP published in the Cochrane Library, is limited by lack of a comprehensive overview.

Objectives: To summarise the evidence from Cochrane Reviews of the efficacy, effectiveness, and safety of systemic pharmacological interventions for adults with non-specific LBP.

Comparative effectiveness and safety of analgesic medicines for adults with acute non-specific low back pain: systematic review and network meta-analysis.

Objective: To evaluate the comparative effectiveness and safety of analgesic medicines for acute non-specific low back pain.

Design: Systematic review and network meta-analysis.

Data Sources: Medline, PubMed, Embase, CINAHL, CENTRAL, ClinicalTrials.

The cross-cultural adaptation, validity, and reliability of the Spanish version of the Fremantle Back Awareness Questionnaire.

Introduction: In chronic low back pain (CLBP), disturbed body image has been highlighted as a contributor to the condition and a potential target for treatment. The Fremantle Back Awareness Questionnaire (FreBAQ) allows its assessment. Following international guidelines for the cross-cultural translation of questionnaires, we aimed to translate the FreBAQ into Spanish (FreBAQ-S) and validate the new questionnaire in a sample of Spanish-speaking people with CLBP.

Effectiveness of Cognitive Functional Therapy for Reducing Pain and Disability in Chronic Low Back Pain: A Systematic Review and Meta-analysis.

We aimed to evaluate whether cognitive functional therapy (CFT) is an effective treatment for adults with chronic low back pain (LBP). Intervention systematic review with meta-analysis. We searched 4 electronic databases (CENTRAL, CINAHL, MEDLINE, and Embase) and 2 clinical trial registers (ClinicalTrials.

"My Back is Fit for Movement": A Qualitative Study Alongside a Randomized Controlled Trial for Chronic Low Back Pain.

A new wave of treatments has emerged to target nervous system alterations and maladaptive conceptualizations about pain for chronic low back pain. The acceptability of these treatments is still uncertain. We conducted a qualitative study alongside a randomized controlled trial to identify perceptions of facilitators or barriers to participation in a non-pharmacological intervention that resulted in clinically meaningful reductions across 12 months for disability compared to a sham intervention.

Development of a booster intervention for graded sensorimotor retraining (RESOLVE) in people with persistent low back pain: A nested, randomised, feasibility trial.

Introduction: Low back pain contributes to an increasing global health burden exacerbated by unsustained improvements from current treatments. There is a need to develop, and test interventions to maintain initial improvements from low back pain treatments. One option is to implement a booster intervention.

The Fit-for-Purpose Model: Conceptualizing and Managing Chronic Nonspecific Low Back Pain as an Information Problem.

Chronic nonspecific low back pain (LBP) is a complex and multifaceted problem. The following Perspective piece tries to help make sense of this complexity by describing a model for the development and maintenance of persistent LBP that integrates modifiable factors across the biopsychosocial spectrum. The Fit-for-Purpose model posits the view that chronic nonspecific LBP represents a state in which the person in pain holds strong and relatively intransient internal models of an immutably damaged, fragile, and unhealthy back, and information that supports these models is more available and trustworthy than information that counters them.

It's safe to move! A protocol for a randomised controlled trial investigating the effect of a video designed to increase people's confidence becoming more active despite back pain.

Introduction: Social media provide promising contemporary platforms for sharing public health information with a broad audience. Before implementation, testing social media campaigns that are intended to engage audiences and initiate behaviour change is necessary. This trial aims to investigate the effectiveness of a public health campaign to increase people's confidence in becoming more active despite low back pain in comparison with no intervention.

Physiotherapy for pain and disability in adults with complex regional pain syndrome (CRPS) types I and II.

Background: Complex regional pain syndrome (CRPS) is a painful and disabling condition that usually manifests in response to trauma or surgery and is associated with significant pain and disability. CRPS can be classified into two types: type I (CRPS I) in which a specific nerve lesion has not been identified and type II (CRPS II) where there is an identifiable nerve lesion. Guidelines recommend the inclusion of a variety of physiotherapy interventions as part of the multimodal treatment of people with CRPS.

Development and measurement properties of the AxEL (attitude toward education and advice for low-back-pain) questionnaire.

Introduction: Clinician time and resources may be underutilised if the treatment they offer does not match patient expectations and attitudes. We developed a questionnaire (AxEL-Q) to guide clinicians toward elements of first-line care that are pertinent to their patients with low back pain.

Methods: We used guidance from the COSMIN consortium to develop the questionnaire and evaluated it in a sample of people with low back pain of any duration.

What messages predict intention to self-manage low back pain? A study of attitudes towards patient education.

This observational study evaluated people's attitudes towards educational statements and tested whether this predicted intention to self-manage low back pain (LBP). People with or without LBP who were older than 18 years and fluent in written English were recruited. Participants completed an online survey asking demographic questions and questions on the presence or absence of LBP, its duration, and intensity.
