Lumbar braces and other assistive devices for treatment of chronic low back pain.

OBJECTIVES: This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the benefits and harms of assistive technologies (i.e. non-rigid and rigid lumbar braces, belts, supports, and devices to assist mobility and gait) for improving pain and function (and consequently reducing disability) in adults with chronic low back pain.

Effectiveness of Rehabilitation Interventions on Adults With COVID-19 and Post-COVID-19 Condition. A Systematic Review With Meta-analysis.

OBJECTIVE: To evaluate the effectiveness of rehabilitation interventions for adults with COVID-19 and post COVID-19 condition (PCC) in all settings. DATA SOURCES: PubMed, EMBASE, CINAHL, Scopus, Web of Science, and Physiotherapy Evidence Database were searched from inception to December 31st, 2021. PROSPERO registration number: CRD42021258553. STUDY SELECTION: We included randomized controlled trials (RCTs) and non-randomized studies of interventions (NRSI) according to the University of Alberta Evidence-based Practice Center. DATA EXTRACTION: One author extracted data using a predetermined Excel form. DATA SYNTHESIS: The meta-analysis indicates uncertain evidence about the effect of pulmonary rehabilitation and self-activities on exercise capacity (MD 65.06, 95% CI 42.87 to 87.25), respiratory function (forced expiratory volume in the first second [FEV1]: MD 0.16, 95% CI 0.05 to 0.28; FEV1/forced vital capacity [FVC]: MD 0.05, 95% CI 0.01 to 0.09; FVC: MD 0.19, 95% CI -0.03 to 0.42) and anxiety (MD -12.03, 95% CI -21.16 to -2.90) in mild COVID-19 and PCC patients. According to the narrative synthesis, including RCTs and NRSI, prone positioning seems to show improvements in vital parameters in severe COVID-19 post intensive care unit (ICU) discharge, pulmonary rehabilitation in activities of daily living, and qigong exercise and acupressure rehabilitation program, and "twist and raise" walking technique in reducing dyspnea and weakness in any degree of severity of COVID-19 and PCC. Functional electrical stimulation-cycling or early rehabilitation programs seem to support a faster recovery in patients with moderate COVID-19 after ICU discharge. Yoga and naturopathy, Mandala coloring, and respiratory exercise seem to reduce anxiety and depression in patients with moderate and mild COVID-19. Cognitive motor training seems to improve cognitive function in PCC patients. CONCLUSIONS: There is very uncertain evidence about the effect of pulmonary rehabilitation on exercise capacity and respiratory function in patients with mild COVID-19 and PCC. Further high-quality research is required to improve the certainty of evidence available to support rehabilitation's crucial role in managing COVID-19.

Prediction of future curve angle using prior radiographs in previously untreated idiopathic scoliosis: natural history from age 6 to after the end of growth (SOSORT 2022 award winner).

PURPOSE: Treatment selection for idiopathic scoliosis is informed by the risk of curve progression. Previous models predicting curve progression lacked validation, did not include the full growth/severity spectrum or included treated patients. The objective was to develop and validate models to predict future curve angles using clinical data collected only at, or both at and prior to, an initial specialist consultation in idiopathic scoliosis. METHODS: This is an analysis of 2317 patients with idiopathic scoliosis between 6 and 25 years old. Patients were previously untreated and provided at least one prior radiograph prospectively collected at first consult. Radiographs were re-measured blinded to the predicted outcome: the maximum Cobb angle on the last radiograph while untreated. Linear mixed-effect models were used to examine the effect of data from the first available visit (age, sex, maximum Cobb angle, Risser, and curve type) and from other visits while untreated (maximum Cobb angle) and time (from the first available radiograph to prediction) on the Cobb angle outcome. Interactions of the first available angle with time, of time with sex, and time with Risser were also tested. RESULTS: We included 2317 patients (83% of females) with 3255 prior X-rays where 71% had 1, 21.1% had 2, and 7.5% had 3 or more. Mean age was 13.9 ± 2.2yrs and 81% had AIS. Curve types were: 50% double, 26% lumbar/thoracolumbar-lumbar, 16% thoracic, and 8% other. Cobb angle at the first available X-ray was 20 ± 10° (0-80) vs 29 ± 13° (6-122) at the outcome visit separated by 28 ± 22mths. In the model using data at and prior to the specialist consult, larger values of the following variables predicted larger future curves: first available Cobb angle, Cobb angle on other previous X-ray, and time (with Time2 and Time3) to the target prediction. Larger values on the following variables predicted a smaller future Cobb angle: Risser and age at the first available X-ray, time*Risser and time*female sex interactions. Cross-validation found a median error of 4.5o with 84% predicted within 10°. Similarly, the model using only data from the first specialist consult had a median error of 5.5o with 80% of cases within 10° and included: maximum Cobb angle at first specialist consult, Time, Time2, age, curve type, and both interactions. CONCLUSIONS: The models can help clinicians predict how much curves would progress without treatment at future timepoints of their choice using simple variables. Predictions can inform treatment prescription or show families why no treatment is recommended. The nonlinear effects of time account for the rapid increase in curve angle at the beginning of growth and the slowed progression after maturity. These validated models predicted future Cobb angle with good accuracy in untreated idiopathic scoliosis over the full growth spectrum.

Influence of Specific Interventions on Bracing Compliance in Adolescents with Idiopathic Scoliosis-A Systematic Review of Papers Including Sensors' Monitoring.

Adolescent idiopathic scoliosis (AIS) is a common disease that, in many cases, can be conservatively treated through bracing. High adherence to brace prescription is fundamental to gaining the maximum benefit from this treatment approach. Wearable sensors are available that objectively monitor the brace-wearing time, but their use, combined with other interventions, is poorly investigated. The aims of the current review are as follows: (i) to summarize the real compliance with bracing reported by studies using sensors; (ii) to find out the real brace wearing rate through objective electronic monitoring; (iii) to verify if interventions made to increase adherence to bracing can be effective according to the published literature. We conducted a systematic review of the literature published on Medline, EMBASE, CINAHL, Scopus, CENTRAL, and Web of Science. We identified 466 articles and included examples articles, which had a low to good methodological quality. We found that compliance a greatly varied between 21.8 and 93.9% (weighted average: 58.8%), real brace wearing time varied between 5.7 and 21 h per day (weighted average 13.3), and specific interventions seemed to improve both outcomes, with compliance increasing from 58.5 to 66% and brace wearing increasing from 11.9 to 15.1 h per day. Two comparative studies showed positive effects of stand-alone counseling and information on the sensors' presence when added to counseling. Sensors proved to be useful tools for objectively and continuously monitoring adherence to therapy in everyday clinical practice. Specific interventions, like the use of sensors, counseling, education, and exercises, could increase compliance. However, further studies using high-quality designs should be conducted in this field.

Mapping brain structure and function in professional fencers: A model to study training effects on central nervous system plasticity.

Brain magnetic resonance imaging (MRI) studies have shown different patterns of structural and functional reorganization in high-level athletes compared with controls, but little is known about their relationship with interlimb coordination mechanisms. To this aim, we investigated brain structural and functional differences in high-level fencers compared with nonathlete controls and the MRI substrates of interlimb coordination in elite athletes. Fourteen right-handed male fencers (median age = 22.3 years) and 15 right-handed age- and sex-matched healthy subjects (median age = 22.4 years) underwent structural and functional MRI acquisition during the execution of cyclic bimanual-movements as well as during in-phase and antiphase hand/foot-movements of the dominant-right limbs. No between-group differences were found in gray matter volumes and white matter architecture. Active-fMRI showed that controls versus fencers had higher activations in parietal and temporal areas during bimanual-task; whereas fencers versus controls had higher activations in the basal ganglia. During in-phase task, controls versus fencers showed higher activation of right cerebellum, whereas fencers had higher activity mainly in frontal areas. The functional-connectivity (FC) analysis showed that fencers versus controls had an increased FC between left motor cortex and fronto-temporal areas as well as bilateral thalami during the different tasks. Intensive and prolonged fencing activity is associated with brain functional changes mainly involving frontal regions related to high-level motor control and planning of complex tasks. These modifications are likely to reflect an optimization of brain networks involved in motor activities, including interlimb coordination tasks, occurring after intensive training.

MRI of Transcallosal White Matter Helps to Predict Motor Impairment in Multiple Sclerosis.

Background Altered callosal integrity has been associated with motor deficits in patients with multiple sclerosis (MS), but its contribution to disability has, to the knowledge of the authors, not been investigated by using multiparametric MRI approaches. Purpose To investigate structural and functional interhemispheric MRI substrates of global disability at different milestones and upper limb motor impairment in MS. Materials and Methods In this cross-sectional study, healthy control patients and patients with MS (between January 1, 2008, and December 31, 2016) were retrospectively selected from our hospital database. Clinical assessment included Expanded Disability Status Scale (EDSS), nine-hole peg test, and digital finger tapping test. By using structural and resting-state functional MRI sequences, probabilistic tractography of hand corticospinal tract fibers, and transcallosal fibers between hand-motor cortices (hereafter, referred to as hand-M1), supplementary motor areas (SMAs), premotor cortices (PMCs), and voxel-mirror homotopic connectivity (VMHC) were analyzed. Random forest analyses identified the MRI predictors of clinical disability at different milestones (EDSS scores of 3.0, 4.0, 6.0) and upper limb motor impairment (nine-hole peg test and finger tapping test z scores < healthy control patients 5th percentile). Results One-hundred thirty healthy control patients (median age, 39 years; interquartile range, 31-50 years; 70 women) and 340 patients with MS (median age, 43 years; interquartile range, 33-51 years; 213 women) were studied. EDSS 3.0 predictors (n = 159) were global measures of atrophy and lesions together with damage measures of corticospinal tracts and transcallosal fibers between PMCs and SMAs (accuracy, 86%; P = .001-.01). For EDSS 4.0 (n = 131), similar predictors were found in addition to damage in transcallosal fibers between hand-M1 (accuracy, 89%; P = .001-.049). No MRI predictors were found for EDSS 6.0 (n = 70). Nine-hole peg test (right, n = 161; left, n = 166) and finger tapping test (right, n = 117; left, n = 111) impairments were predicted by damage in transcallosal fibers between SMAs and PMCs (accuracy range, 69%-77%; P = .001-.049). VMHC abnormalities did not explain clinical outcomes. Conclusion Structural, not functional, abnormalities at MRI in transcallosal premotor and motor white matter fibers predicted severity of global disability and upper limb motor impairment in patients with multiple sclerosis. The informative role of such predictors appeared less evident at higher disability levels. © RSNA, 2021 Online supplemental material is available for this article.

Sport improved medium-term results in a prospective cohort of 785 adolescents with idiopathic scoliosis braced full time. SOSORT 2018 award winner.

PURPOSE: The association between idiopathic scoliosis (IS) and sports activities remains vague. We aimed to analyse their effect on full-time braced adolescents with IS. METHODS: We retrospectively recruited all the consecutive patients of a tertiary referral Institute of age ≥ 10 (adolescents), with a juvenile (JIS) or adolescent (AIS) IS diagnosis, Risser 0-2, TLSO brace prescription and self-reported adherence ≥ 20 h per day, and follow-up out-of-brace X-rays 18 months after brace prescription. We divided participants into two groups: SPORT (sport twice or more per week) and CONTROL (sport once per week or less). We calculated odds ratio (OR) to compare the outcome of subjects performing to those not performing sport. We ran a logistic regression with covariate adjustment to assess if sports frequency affected the outcomes. RESULTS: Out of 33,311 participants assessed for eligibility, 785 satisfied the inclusion criteria (693 females, age 12.7 ± 1.3 and 40 ± 11° Cobb). The SPORT group consisted of 290 participants and the CONTROL group of 495. The SPORT group showed higher odds of improvement (OR = 1.59, 95%CI = 1.17-2.16, p = 0.0018). The odds of improving increased with the frequency of sports activity (OR = 1.20, 95%CI 1.08-1.34). CONCLUSION: This study shows that sports activities increase the odds of improvement at 18-month follow-up in adolescents with IS treated with a full-time brace. The odds of improvement increase with sports week frequency.

Action observation training promotes motor improvement and modulates functional network dynamic connectivity in multiple sclerosis.

We investigated modifications of resting state dynamic functional network connectivity (dFNC) following a 2-week action observation training (AOT) in 46 right-handed healthy controls (HC) and 41 patients with multiple sclerosis (pwMS) and dominant-hand motor impairment, who were randomized to AOT or control (C) training. PwMS had decreased baseline dFNC versus HC. After training, MS groups improved in right upper limb functions, mainly in AOT, and showed dFNC increase (larger in MS-AOT vs MS-C) in sensorimotor and cognitive networks (p range, ⩽0.001-0.01). Both HC groups showed decreased dFNC over time (p range, ⩽0.001-0.01). Clinical improvements following interventions correlated with sensorimotor and cognitive dFNC changes, suggesting their possible role in motor recovery.

MRI correlates of clinical disability and hand-motor performance in multiple sclerosis phenotypes.

BACKGROUND: Hand-motor impairment affects a large proportion of multiple sclerosis (MS) patients; however, its substrates are still poorly understood. OBJECTIVES: To investigate the association between global disability, hand-motor impairment, and alterations in motor-relevant structural and functional magnetic resonance imaging (MRI) networks in MS patients with different clinical phenotypes. METHODS: One hundred thirty-four healthy controls (HC) and 364 MS patients (250 relapsing-remitting MS (RRMS) and 114 progressive MS (PMS)) underwent Expanded Disability Status Scale (EDSS) rating, nine-hole peg test (9HPT), and electronic finger tapping rate (EFTR). Structural and resting state (RS) functional MRI scans were used to perform a source-based morphometry on gray matter (GM) components, to analyze white matter (WM) tract diffusivity indices and to perform a RS seed-based approach from the primary motor cortex involved in hand movement (hand-motor cortex). Random forest analyses identified the predictors of clinical impairment. RESULT: In RRMS, global measures of atrophy and lesions together with measures of structural damage of motor-related regions predicted EDSS (out-of-bag (OOB)-R2 = 0.19, p-range = <0.001-0.04), z9HPT (right: OOB-R2 = 0.14; left: OOB-R2 = 0.24, p-range = <0.001-0.03). No RS functional connectivity (FC) abnormalities were identified in RRMS models. In PMS, cerebellar and sensorimotor regions atrophy, cerebellar peduncles integrity and increased RS FC between left hand-motor cortex and right inferior frontal gyrus predicted EDSS (OBB-R2 = 0.16, p-range = 0.02-0.04). CONCLUSION: In RRMS, only measures of structural damage contribute to explain motor impairment, whereas both structural and functional MRI measures predict clinical disability in PMS. A multiparametric MRI approach could be relevant to investigate hand-motor impairment in different MS phenotypes.

Imaging correlates of hand motor performance in multiple sclerosis: A multiparametric structural and functional MRI study.

BACKGROUND: Hand motor impairment has considerable effects on daily-life activities of patients with multiple sclerosis (pwMS). Understanding its anatomo-functional substrates is relevant to provide more specific therapeutic interventions. OBJECTIVES: To investigate the association between hand motor performance and anatomo-functional magnetic resonance imaging (MRI) abnormalities in pwMS. METHODS: A total of 134 healthy controls (HC) and 366 pwMS underwent the Nine-Hole-Peg-Test (9HPT), structural and resting state (RS) functional MRI. Multivariate analyses identified the independent predictors of hand motor performance. RESULTS: PwMS versus HC showed widespread gray matter atrophy, microstructural white matter abnormalities, and decreased RS functional connectivity in motor and cognitive networks. Predictors of worse right-9HPT (R2 = 0.52) were decreased right superior cerebellar peduncle and right lemniscus fractional anisotropy (FA) (p ⩽ 0.02), left angular gyrus atrophy (p < 0.003), decreased RS connectivity in left superior frontal gyrus, and left posterior cerebellum (p < 0.001). Worse left 9HPT (R2 = 0.56) was predicted by decreased right corticospinal FA (p = 0.003), atrophy of left anterior cingulum and left cerebellum (p ⩽ 0.02), decreased RS connectivity of left lingual gyrus and right posterior cerebellum in cerebellar and executive networks (p ⩽ 0.02). CONCLUSION: Structural and functional abnormalities of regions involved in motor functions contribute to explain motor disability in pwMS. The integration of clinical and advanced MRI measures contributes to improve our understanding of multiple sclerosis clinical manifestations.

Functional and structural plasticity following action observation training in multiple sclerosis.

BACKGROUND: Hand motor deficits contribute to multiple sclerosis (MS)-related disability. Action observation training (AOT) is promising to improve upper limb function in neurologic patients. OBJECTIVES: In this preliminary study, we investigated AOT effects on dominant-hand motor performance in MS patients with upper limb motor impairment and performed an explorative analysis of their anatomical and functional magnetic resonance imaging (MRI) substrates. METHODS: In total, 46 healthy controls (HC) and 41 MS patients with dominant-hand motor impairment were randomized to AOT (HC-AOT = 23; MS-AOT = 20; watching daily-life action videos and execution) or control-training (HC-Control = 23; MS-Control = 21; watching landscapes videos and execution). Behavioral, structural, and functional (at rest and during object manipulation) MRI scans were acquired before and after a 2-week training. RESULTS: After training, MS groups improved in right upper limb functions, mainly in AOT group (p from 0.02 to 0.0001). All groups showed regional increased and decreased gray matter volume, with specific AOT effects in fronto-temporal areas in MS-AOT (p < 0.001), without white matter (WM) integrity modifications. Increased and reduced recruitments of the action observation matching system and its connections in MS-AOT were found (p < 0.001). Motor improvements were correlated with volumetric and functional MRI modifications (r from -0.78 to 0.77, p < 0.001). CONCLUSION: The 10-day AOT promotes clinical improvements in MS patients through structural and functional modifications of the action observation matching system.

What type of physical exercise works best to improve movement and quality of life for people with Parkinson's disease? - A Cochrane Review summary with commentary.

BACKGROUND: Parkinson's disease (PD) is a progressive neurodegenerative disorder diagnosed by motor symptoms of bradykinesia, in combination with tremor, rigidity, or postural instability. Many studies document the effects of exercise-based interventions, but the benefit of different exercise types remains unclear. OBJECTIVE: To provide a commentary on the Cochrane Review by Ernst et al. on the effectiveness of different types of physical exercise regarding motor signs, Quality of Life (QoL), and the occurrence of adverse events. METHODS: A systematic search was performed in CENTRAL, MEDLINE, Embase, and other databases. The search was performed also in trial registries, conference proceedings, and reference list of identified studies. RESULTS: The review included 154 RCTs (with 7837 participants). The network meta-analyses (NMAs) on the severity of motor signs and QoL included data from 60 (2721 participants) and 48 (3029 participants) trials, respectively. The evidence from the NMA suggests that dance, gait/balance/functional training probably have a moderate beneficial effect on the severity of motor signs, and multi-domain training probably has a small beneficial effect on the severity of motor signs. Endurance, aqua-based, strength/resistance, and mind-body training might have a small beneficial effect on the severity of motor signs. In addition, aqua-based training probably has a large beneficial effect on QoL, and mind-body, gait/balance/functional, and multi-domain training and dance might have a small beneficial effect on QoL. CONCLUSIONS: Current evidence supports the promotion of physical exercise among people with PD, identifying only small differences between exercises in influencing the severity of motor signs and QoL.

Do implementation interventions improve evidence-based care in acute stroke settings? A Cochrane Review summary with commentary.

BACKGROUND: Evidence on acute stroke management is continuously growing. Stroke units are often associated with better access to high-level evidence-based practices, but even there, recommendations can be inconsistently delivered to patients with stroke. Implementation interventions are strategies designed to improve the application of evidence-based care. OBJECTIVE: To provide a commentary on the Cochrane Review by Lynch et al. on the effects of implementation interventions on adherence to evidence-based recommendations by health professionals working in acute stroke units. METHODS: A systematic search was performed in CENTRAL, MEDLINE, Embase, and other databases. The search was also performed in grey literature databases, trial registries, systematic reviews and primary studies, as well as in the reference list of identified studies. RESULTS: The review included seven cluster-randomized trials (with 42,489 participants). Studies compared the implementation of strategies composed of different parts (multifaceted) to no intervention, or a multifaceted strategy vs another intervention. These strategies were aimed at changing and improving the delivery of care in the hospital. It included health professional participants, such as nurses, physicians and allied health professionals. The authors concluded that there was uncertainty whether implementation strategies compared with no intervention have any effect on patients receiving evidence-based care during their stroke unit admission. Implementation interventions compared to no intervention probably have little or no effect on the risk of patients dying or being disabled or dependent, and probably do not change patients' hospital length of stay. CONCLUSION: Due to the very low certainty of evidence, there is uncertainty whether a multifaceted implementation intervention, compared to no intervention, can improve adherence to evidence-based recommendations in acute stroke settings.

Developing Physiotherapy in Primary Health Care: A First Snapshot from the Italian Metropolitan City of Milan.

INTRODUCTION: Since the COVID-19 pandemic, the Italian National Health Service (NHS) has been undergoing a structural reform shifting focus from hospital-centered care to smaller, intermediate, or primary health facilities closer to the community (e.g., community hospitals and community houses). This reorganization should include rehabilitation and physiotherapy, but the actual spread of these services is still unclear. OBJECTIVE: This study explored the number and characteristics of community-based physiotherapy services in the Metropolitan City of Milan (Italy). METHODS: Between April and May 2024, we distributed a structured, anonymous online survey about community physiotherapy services and users to all Directors of the Health and Social Care Professions Departments (DAPSS) in the Metropolitan City of Milan. We used descriptive statistics to analyze the number of community houses offering physiotherapy services, the specific intervention areas, and access modalities. RESULTS: Six out of seven DAPSS Directors completed the survey (87%). Thirty-seven community houses were reported in the area, with fourteen of these offering physiotherapy services. In most of them, physiotherapy was a primary reason for access following a general practitioner's prescription. Five out of six responders reported that rehabilitation needs were mainly assessed by specialists in Physical and Rehabilitation Medicine, with physiotherapists involved in the assessment process in two cases. Physiotherapists primarily handled the intervention phase, dealing mainly with orthopedic and neurological conditions. DAPSS Directors noted that additional physiotherapy initiatives focusing on prevention will be implemented. CONCLUSIONS: Physiotherapy services are becoming available in the Metropolitan City of Milan. However, more efforts are needed to facilitate access and ensure tailored assessment and effective interventions, particularly in preventive care. Future investigations should help to better define the number and the characteristics of the patients who can most benefit from this type of care, the number of sessions they need, and with what types of intervention; it would be also necessary to better define the communication network in the area that allows doctors, health professionals, and patients to be informed about this possibility.

Effectiveness of rehabilitation interventions in adults with asthma: a systematic review and meta-analysis.

OBJECTIVE: To evaluate the effectiveness of pulmonary rehabilitation (PR) programs and other rehabilitation interventions in adults with asthma. DESIGN: Systematic review and meta-analysis. RESULTS: MEDLINE (PubMed), EMBASE, Cumulative Index to Nursing & Allied Health Literature and CENTRAL were searched from inception to 31 May 2023. PROSPERO registration number: CRD42022331440. Thirty-six randomised controlled trials (RCTs) were analysed, and only 26 were pooled in the meta-analysis due to the heterogeneity of comparisons and outcomes across the studies. Pulmonary rehabilitation, compared with education associated with breathing exercises, may result in little to no difference in the Asthma Quality of Life Questionnaire (AQLQ) (mean difference 0.01 score, 95% confidence interval -0.48 to 0.50, 163 participants, three studies, low certainty). CONCLUSION: Our findings show that pulmonary rehabilitation, compared with education associated with breathing exercises, may result in little to no difference in the impact of asthma on health-related quality of life. Overall, the certainty of evidence was low or very low preventing any firm conclusion on the effects of single or combined rehabilitation interventions.

Designing studies and reviews to produce informative, trustworthy evidence about complex interventions in rehabilitation: a narrative review and commentary.

According to Cochrane Rehabilitation's recently published definition for research purposes, rehabilitation is inherently complex. Rehabilitation teams frequently implement multiple strategies concurrently, draw on input from a range of different health professionals, target multiple outcomes, and personalize therapeutic plans. The success of rehabilitation lies not only in the specific therapies employed, but also in how they are delivered, when they are delivered, and the capability and willingness of patients to engage in them. In 2021, the UK Medical Research Council (MRC) and the National Institute of Health Research (NIHR) released the second major update of its framework for developing and evaluating complex interventions. This framework has direct relevance to the development and implementation of evidence-based practice in the field of rehabilitation. While previous iterations of this framework positioned complex interventions as anything that involved multiple components, multiple people, multiple settings, multiple targets of effect, and behavior change, this latest framework expanded on this concept of complexity to also include the characteristics and influence of the context in which interventions occur. The revised MRC-NIHR framework presents complex intervention research as comprising the following four inter-related and overlapping phases: 1) development or identification of the intervention; 2) feasibility; 3) evaluation; and 4) implementation, with different methods and tools required to address each of these phases. This paper provides an overview of the MRC-NIHR framework and its application to rehabilitation, with examples from past research. Rehabilitation researchers are encouraged to learn about the MRC-NIHR framework and its application. Funders of rehabilitation research are also encouraged to place greater emphasis on supporting studies that involve the right design to address key uncertainties in rehabilitation clinical practice. This will require investment into a broader range of types of research than simply individual-level randomized controlled trials. Rehabilitation research can both learn from and contribute to future iterations of the MRC-NIHR framework as it is an excellent environment for exploring complexity in clinical practice.

A Proposal for a Multidisciplinary Integrated Oral Health Network for Patients Undergoing Major Orthopaedic Surgery (IOHN-OS).

The passing of the years of life physiologically leads to the accumulation of changes in tissues in the oral cavity, influencing dentition, chewing and swallowing mechanisms, and the oral microbiota. Some diseases and medications can aggravate oral symptoms and negatively influence eating behaviours, increasing the likelihood of becoming malnourished. This could make older individuals more vulnerable to complications when undergoing major orthopaedic surgery. Hidden infection foci in the oral cavity are a recognised cause of post-operative periprosthetic joint infections. Dysfunctional oral problems might also compromise feeding after surgery when good nutrition represents a fundamental aspect of a proper recovery. To manage these shortcomings, in this article, the authors hypothesise a multidisciplinary path of care named the Integrated Oral Health Network applied to major Orthopaedic Surgery (IOHN-OS). This peri-operative initiative would include pre-operative oral health screening and risk management by a dental team, patient education programmes before and after surgery, and bedside gerodontology actions like oral care and meal and eating support for fragile individuals. The IOHN-OS has the potential to reshape the concept of suitability for major orthopaedic surgery and generate momentum for designing community-based surveillance programmes that can keep the mouths of older subjects healthy for a long time.

Relevance and use of health policy, health systems and health services research for strengthening rehabilitation in real-life settings: methodological considerations.

Research on health policy, systems, and services (HPSSR) has seen significant growth in recent decades and received increasing attention in the field of rehabilitation. This growth is driven by the imperative to effectively address real-life challenges in complex healthcare settings. A recent resolution on 'Strengthening rehabilitation in health systems' adopted by the World Health Assembly emphasizes the need to support societal health goals related to rehabilitation, particularly to promote high-quality rehabilitation research, including HPSSR. This conceptual paper, discussed with the participants in the 5th Cochrane Rehabilitation Methodological Meeting held in Milan on September 2023, outlines study designs at diverse levels at which HPSSR studies can be conducted: the macro, meso, and micro levels. It categorizes research questions into four types: those framed from the perspective of policies, healthcare delivery organizations or systems, defined patient or provider populations, and important data sources or research methods. Illustrative examples of appropriate methodologies are provided for each type of research question, demonstrating the potential of HPSSR in shaping policies, improving healthcare delivery, and addressing patient and provider perspectives. The paper concludes by discussing the applicability, usefulness, and implementation of HPSSR findings, and the importance of knowledge translation strategies, drawing insights from implementation science. The goal is to facilitate the integration of research findings into everyday clinical practice to bridge the gap between research and practice in rehabilitation.

Current Knowledge on the Different Characteristics of Back Pain in Adults with and without Scoliosis: A Systematic Review.

Patients with scoliosis have a high prevalence of back pain (BP). It is possible that scoliosis patients present with specific features when experiencing back or leg pain pathology. The aim of this systematic review is to report the signs, symptoms and associated features of BP in patients with scoliosis compared to adults without scoliosis during adulthood. From inception to 15 May 2023, we searched the following databases: PubMed, EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Scopus. We found 10,452 titles, selected 25 papers for full-text evaluation and included 8 in the study. We found that scoliosis presents with asymmetrical pain, most often at the curve's apex, eventually radiating to one leg. Radiating symptoms are usually localised on the front side of the thigh (cruralgia) in scoliosis, while sciatica is more frequent in non-scoliosis subjects. These radiating symptoms relate to rotational olisthesis. The type and localization of the curve have an impact, with lumbar and thoracolumbar curves being more painful than thoracic. Pain in adults with scoliosis presents specific features: asymmetrical localization and cruralgia. These were the most specific features. It remains unclear whether pain intensity and duration can differentiate scoliosis and non-scoliosis-related pain in adults.
