Adherence to the PRISMA statement and its association with risk of bias in systematic reviews published in rehabilitation journals: A meta-research study

BackgroundSystematic reviews (SRs) and meta-analyses are essential resources for the clinicians. They allow to evaluate the strengths and the weaknesses of the evidence to support clinical decision-making if they are adequately reported. Little is known in the rehabilitation field about the completeness of reporting of SRs and its relationship with the risk of bias (ROB).ObjectivesPrimary: 1) To evaluate the completeness of reporting of systematic reviews (SRs) published in rehabilitation journals by evaluating their adherence to the PRISMA 2009 checklist, 2) To investigate the relationship between ROB and completeness of reporting. Secondary: To study the association between completeness of reporting and journals and study characteristics.MethodsA random sample of 200 SRs published between 2011 and 2020 in 68 rehabilitation journals was indexed under the “rehabilitation” category in the InCites database. Two independent reviewers evaluated adherence to the PRISMA checklist and assessed ROB using the ROBIS tool. Overall adherence and adherence to each PRISMA item and section were calculated. Regression analyses investigated the association between completeness of reporting, ROB, and other characteristics (impact factor, publication options, publication year, and study protocol registration).ResultsThe mean overall PRISMA adherence across the 200 studies considered was 61.4%. Regression analyses show that having a high overall ROB is a significant predictor of lower adherence (B=-7.1%; 95%CI -12.1, -2.0). Studies published in fourth quartile journals displayed a lower overall adherence (B= -7.2%; 95%CI -13.2, -1.3) than those published in first quartile journals; the overall adherence increased (B= 11.9%; 95%CI 5.9, 18.0) if the SR protocol was registered. No association between adherence, publication options, and publication year was found.ConclusionReporting completeness in rehabilitation SRs is suboptimal and is associated with ROB, impact factor, and study registration. Authors of SRs should improve adherence to the PRISMA guideline, and journal editors should implement strategies to optimize the completeness of reporting.     

Effect of acupuncture in eczema: An overview of systematic reviews

BackgroundEczema is a common chronic relapsing inflammatory skin disease, which is characterized by intense itching. Acupuncture can be effective for eczema, and it is thus regarded as a common complementary treatment.ObjectiveThe intention of this overview is to methodically appraise and synthesize evidence about systematic reviews/meta-analyses (SRs/MAs) on acupuncture in eczema.MethodsWe searched for SRs/MAs of acupuncture with eczema in eight databases. We evaluated the methodological quality by Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2), the reporting quality with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020 Checkist), and the evidence quality according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.ResultsA total of 7 SRs/MAs were included. According to AMSTAR-2, all the SRs/MAs included were categorized as critically low-quality. According to the PRISMA 2020 checklist, none of the reviews completed all the 27 items, thus their compliance was relatively weak. On the base of GRADE system, 2 of the 12 outcomes were rated as moderate, and 5 outcomes were rated as low-quality, while the others were regarded as very low-quality.ConclusionCompared with the control group, the included reviews of the acupuncture group were more effective and safer; however, the conclusion should be treated cautiously because the quality of evidence was not high enough to support it. In order to improve the quality, more rigorous, standardized, and comprehensive SRs/MAs need designing in the future.     

Acupuncture for treatment of anxiety,an overview of systematic reviews

PurposeTo evaluate the methodological quality and summarize evidence of important outcomes of systematic reviews (SRs)/Meta analyses (MAs) of acupuncture for anxiety.MethodsWe conducted a comprehensive literature search for SRs/MAs in PubMed, EMBASE, Cochrane library, Chinese Biomedical Databases (CBM), Wanfang database and China National Knowledge Infrastructure (CNKI) until November 30, 2018. Three reviewers independently extracted data and assessed the methodological quality of the reviews according to the Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2), the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) was used to rate the quality of evidence. In the pre-experiment, we used the intra-class correlation coefficient (ICC) to assess reviewer agreement, the ICC value for overall score was 0.978.ResultsTen reviews were included. The assessment results of AMSTAR-2 showed that the methodological quality of all included studies was critically low. The lowest score were item “provide a list of excluded studies and justify the exclusions” and item “report sources of funding for the included studies”, none of studies provided information about the above two items, followed by the “providing a priori design” item with only two (20%) studies conforming to this item. For GRADE, of the 7 outcomes, high quality evidence was provided in only 1 (14.3%), moderate in 2 (28.6.7%), and low in 4 (57.1%).ConclusionAlthough most of the included reviews indicated that acupuncture group was more effective than control group in the treatment of anxiety, more importantly, the methodological quality of the included reviews and the quality of evidence were low. More high-quality evidence is needed to determine whether acupuncture is more effective than other treatments.     

Cognitive interventions for mild cognitive impairment and dementia: An overview of systematic reviews

PurposeConducting an overview of systematic reviews (SRs)/Meta analyses (MAs) to assess the effectiveness of cognitive interventions on participants with mild cognitive impairment (MCI) or dementia and evaluate the methodological quality of SRs/MAs.MethodsPubMed, EMBASE, Cochrane library, Web of science, China National Knowledge Infrastructure (CNKI) and Chinese Biomedical Databases (CBM) were systematically searched from inception to January 1, 2019 to identify SRs/MAs. Three reviewers independently screened the articles, extracted data and assessed the quality of the included studies according to the Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2), the Grading of Recommendations Assessment Development and Evaluation (GRADE) was used to evaluate the quality of evidence.ResultsA total of 22 reviews were included. New meta-analyses (36 RCTs) showed that cognitive interventions were more effective than routine therapies for the alleviation of MCI and dementia symptoms (SMD: 0.62; 95%CI: 0.47, 0.78; I² = 53.9%). The results of AMSTAR-2 showed that the methodological quality of most included studies was critically low, and two reviews were low quality. The lowest score was item 10, none of reviews reported on the sources of funding for the included studies. Followed by the “provide a list of excluded studies and justify the exclusions” item with only one (4.5%) reviews conforming to this item. Results of GRADE manifested that moderate quality evidence was provided in 11 reviews (39.3%), 12 (42.9%) were low quality and 5 (17.8%) were very low.ConclusionThe present SRs/MAs indicated that persons with MCI or dementia could benefit from cognitive interventions. Future trial designs should focus on measuring changes in individual specific cognitive functions. More high-quality evidence is needed to further determine the effectiveness of cognitive interventions.     

Ginger for health care: An overview of systematic reviews

ObjectivesTo summarize the evidence from systematic reviews (SRs) and meta-analyses that evaluated the efficacy of ginger in treating any conditions and critically assess the quality of these evidence.MethodsA systematic search of the literature was conducted from inception until February 28, 2019 using the PubMed, EMBASE, Web of science, Cochrane library, and four Chinese databases. Literature selection and data extraction were conducted by two independent reviewers. The quality of SRs was evaluated using the AMSTAR-2 tool. The GRADE system was used to assess the quality of evidence.ResultsTwenty-seven SRs were included. The number of included studies were various, range from 3 to 27. The condition with the most included SRs was nausea and vomiting (n = 12, 44.4%). Many SRs showed a promising efficacy of ginger, including nausea and vomiting, metabolic syndrome and pain, while the effect of ginger for platelet aggregation failed to draw a certain conclusion. The quality of SRs was heterogeneous. All of included SRs well complied with the Item 1 (“research questions included the components of PICO”) and Item 3 (“explained selection of the study designs for inclusion”). Twenty review failed to provide registration information. Only one SR reported the sources of funding for studies included.ConclusionsIn our overview, most of SRs suggest ginger is a promising herbal medicine for health care, which is beneficial for nausea and vomiting, metabolic syndrome and pain. However, considering the limited quality of included evidence and heterogeneity of different clinical trials, more well-design studies are required to confirm the conclusion further.     

The effectiveness of acupuncture for Parkinson’s disease: An overview of systematic reviews

ObjectivesAcupuncture is an alternative therapy for Parkinson’s disease (PD), but its efficacy and safety are controversial. This overview aimed to summarize the existing evidence from systematic reviews (SRs) and meta-analyses (MAs) in order to assess the effectiveness of acupuncture as a treatment for PD.MethodsSeven electronic databases were searched from their inception until July 2019. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) and Assessment of Multiple Systematic Reviews 2 (AMSTAR2) checklists were used to assess evidence quality and methodological quality, respectively. The outcomes of study were calculated using mean differences (MDs) and risk ratios (RRs) with 95 % confidence intervals (CIs). A meta-analysis was performed using RevMan 5.3 software.ResultsA total of 12 SRs/MAs were included. All 12 SRs/MAs had more than one critical weakness in AMSTAR 2 and were considered of critically low methodological quality. The quality of evidence was unsatisfactory according to the GRADE checklist. Meta-analyses showed that acupuncture combined with drug for the treatment of PD can significantly improve the total effectiveness rate compared with drug alone (RR = 1.25, 95 % CI 1.16–1.34, P < 0.001). It was also found that acupuncture combined with drug significantly improved the UPDRS I–IV total summed scores (WMD=−6.18, 95 % CI -10.32 to –2.04, P < 0.001) and Webster scores (WMD=−4.20, 95 % CI -7.59 to –0.81, P < 0.001).ConclusionAcupuncture might improve the UPDRS score, Webster score, and total effective rate in treatment of PD. It might be a safe and useful adjunctive treatment for patients with PD. However, we should interpret the findings of these reviews with caution, considering the overall limited methodological and reporting quality.     

Effectiveness of nonpharmacological interventions to prevent adverse events in the intensive care unit: A review of systematic reviews

BackgroundDifferent types of interventions have been assessed for the prevention of adverse events. However, determining which patient-safety practice is most effective can be challenging when there is no systematised evidence synthesis. An overview following the best methodological standards can provide the best reliable integrative evidence.ObjectivesThe objective of this study was to provide an overview of effectiveness nonpharmacological interventions aimed at preventing adverse events in the intensive care unit.MethodsA review of systematic reviews (SRs) was conducted according to the Cochrane Handbook and PRISMA recommendations. PubMed, CINAHL, and Cochrane Library were searched for SRs published until March 2022. Two reviewers independently assessed the study’s quality, using AMSTAR-2, and extracted data on intervention characteristics and effect on prevention of adverse events.ResultsThirty-seven SRs were included, and 27 nonpharmacological interventions were identified to prevent 11 adverse events. Most of the reviews had critically low methodological quality. Among all the identified interventions, subglottic secretion drainage, semirecumbent position, and kinetic bed therapy were effective in preventing ventilator-associated pneumonia; the use of earplugs, early mobilisation, family participation, and music in reducing delirium; physical rehabilitation in improving muscle strength; use of respiratory support in preventing reintubation; the use of a computerised physician order entry system in reducing risk of medication errors; and the use of heated water humidifier was effective in reducing artificial airway occlusion.ConclusionsSome nonpharmacological interventions reduced adverse events in the intensive care setting. These findings should be interpreted carefully due to the low methodological quality. SRs on preventing adverse events in the intensive care unit should adhere to quality assessment tools so that best evidence can be used in decision-making.     

Shall we use cryotherapy in the treatment in surgical procedures,in acute pain or injury,or in long term pain or dysfunction? - A systematic review

PurposeThis review aimed to evaluate the certainty of evidence for the use of cryotherapy in patients with musculoskeletal disorders.MethodsPubMed, Embase, Cochrane Library and AMED were searched from January 2000 to January 2018 (update June 2019) for systematic reviews (SRs) and randomized controlled trials (RCTs) reporting outcomes on pain, swelling, range of motion (ROM), function, blood loss, analgesic use, patient satisfaction and adverse advents. The papers were categorised into: surgical procedures, acute pain or injury and long-term pain or dysfunction. Methodological quality and risk of bias were assessed using the AMSTAR and the Swedish Health Technology Assessment instruments. Level of certainty of evidence was synthesized using GRADE.Study selectionEight SRs and 50 RCTs from a total of 6027 (+839) were included. In total 34 studies evaluated cryotherapy in surgical procedures, twelve evaluated cryotherapy use in acute pain or injury and twelve studies evaluated cryotherapy in long-term pain and dysfunction.ResultsThe certainty of evidence is moderate (GRADE III) after surgical procedures to reduce pain, improve ROM, for patient satisfaction and few adverse events are reported. Cryotherapy in acute pain and injury or long-term pain and dysfunction show positive effects but have a higher number of outcomes with low certainty of evidence (GRADE II).ConclusionCryotherapy may safely be used in musculoskeletal injuries and dysfunctions. It is well tolerated by patients. More advanced forms of cryotherapy may accentuate the effect. Future research is needed where timing, temperature for cooling, dose (time) and frequency are evaluated.     

The efficacy of acupuncture for attention deficit hyperactivity disorder (ADHD): An overview of systematic reviews and meta-analyses

BackgroundAttention deficit hyperactivity disorder (ADHD) is one of the most common neurological and mental developmental disorders in children. Published systematic reviews (SRs) and meta-analyses (MAs) concerning the use of acupuncture for ADHD have compared the efficacy of acupuncture treatment to that of drug therapies. However, the quality of these articles has not been evaluated and the evidence varies widely.ObjectiveTo summarize and assess the efficacy of acupuncture for ADHD based on existing SRs and MAs.MethodsA systematic search of the literature was conducted from inception until September 16 2021, using seven electronic databases. The AMSTAR-2 tool was used to evaluate the quality of SRs and MAs, and the GRADE system was used to assess the quality of evidence.ResultsThere are a total of five SRs and MAs included in this overview. Using the AMSTAR-2, three articles were rated as having ‘Low’ quality, while two were rated as having of ‘Critically Low’ quality. The GRADE system was used to measure the quality of evidence for ten outcomes (five response rate outcomes, three Conners’ Index of Hyperactivity (CIH) score outcomes, one Conners’ rating scale score outcome, and one Chinese medicine syndrome outcome) across the five included MAs. Four of the ten outcomes demonstrated ‘moderate’ quality, four demonstrated ‘low’ quality, and two demonstrated ‘very low’ quality. The risk of bias and inconsistency accounted for most downgrading factors in the included reviews.ConclusionIt is still debatable whether acupuncture is efficacious in improving the CIH score and the Response rate. Considering the heterogeneity of clinical trials and the fact that this study did not search and evaluate the relevant data of each randomized controlled trial, large-sample and high-quality randomized controlled trials are still needed to draw reliable conclusions regarding acupuncture's role in treating ADHD. Due to the poor quality of existing available evidence, little inference can be drawn from the included studies.     

The Effectiveness of Tai Chi in Patients With Breast Cancer: An Overview of Systematic Reviews and Meta-Analyses

BackgroundAs a mind-body exercise, Tai Chi (TC) may have a positive impact on physical function and psychological well-being in patients with breast cancer (BC). The aim of this current overview of systematic reviews (SRs) and meta-analyses (MAs) was to identify and summarize the existing evidence regarding the effectiveness of TC in patients with BC.MethodsA computerized search of electronic databases was performed to identify relevant SRs/MAs of TC related to BC from inception to June 2020. The Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklists were used to assess the methodological quality and reporting quality of SRs and MAs, respectively. The Grades of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used to assess the evidence quality of outcome measures.ResultsSix SRs/MAs in which quantitative synthesis was used to assess various outcomes of TC related to BC were included in this overview. The quality of the SRs/MAs and the evidence quality of the outcome measures were generally unsatisfactory. The limitations of the past SRs/MAs were the lack of a protocol and registration, a list of excluded studies, or inadequately reported computational details of meta-analyses. The critical problems were that the qualitative data synthesis relied on the trials with small sample sizes and of critical low quality.ConclusionsTC is possibly beneficial to BC treatment. However, further rigorous and comprehensive studies are required to provide robust evidence for definitive conclusions.     

One in 11 Cochrane Reviews Are on Rehabilitation Interventions,According to Pragmatic Inclusion Criteria Developed by Cochrane Rehabilitation

ObjectiveTo identify all published protocols and reviews in the Cochrane Library relevant to the scope of practice of rehabilitation; to test pragmatic criteria to identify rehabilitation interventions; to begin categorizing reviews according to the professionals involved in delivering the intervention and broad areas of clinical practice.Data SourcesCochrane Database of Systematic Reviews.Study SelectionWe screened all published reviews and protocols in the Cochrane library.Data ExtractionWe built an online relational database into which we imported titles and abstracts of all reviews and protocols published in the Cochrane Library from 1996 to August 2018. We recruited rehabilitation professionals worldwide through Cochrane Rehabilitation’s social media to find and tag rehabilitation reviews in this database. One rehabilitation physician and 1 allied health professional independently tagged each title against prespecified criteria. The Cochrane Rehabilitation Review Committee examined disagreements between contributors for any uncertainties about how to categorize a review. We revised and improved our preliminary criteria for identifying rehabilitation interventions as the work progressed.Data SynthesisWe identified that 9.4% of all Cochrane publications (894/9471 reviews and protocols) are directly relevant to the practice of rehabilitation. The professional groups whose interventions were most frequently the subject of rehabilitation reviews and protocols were rehabilitation physicians and physical therapists. We also identified a final list of inclusion and exclusion criteria for reviews on rehabilitation interventions.ConclusionMany Cochrane Reviews are directly relevant to rehabilitation. Cochrane needs to consider the rehabilitation community a major stakeholder in all its work. The pragmatic criteria we tested are offered for future discussions on the identification and categorization of rehabilitation interventions by stakeholders worldwide. This work will support the spread of content from the Cochrane Library to rehabilitation professionals and guide future research.     

Completeness of Reporting Is Suboptimal in Randomized Controlled Trials Published in Rehabilitation Journals,With Trials With Low Risk of Bias Displaying Better Reporting: A Meta-research Study

ObjectivePrimary: To evaluate the completeness of reporting of randomized controlled trials (RCTs) published in rehabilitation journals through the evaluation of the adherence to the Consolidated Standards of Reporting Trials (CONSORT) checklist and investigate the relationship between reporting and risk of bias (ROB). Secondary: To study the association between completeness of reporting and the characteristics of studies and journals.Data SourcesA random sample of 200 RCTs published between 2011 and 2020 in 68 rehabilitation journals indexed under the “rehabilitation” category in the InCites Journal Citation Report.Study SelectionOne reviewer evaluated the completeness of reporting operationalized as the adherence to the CONSORT checklist. Two independent reviewers evaluated the ROB using the Cochrane risk-of-bias 2.0 tool.Data ExtractionOverall adherence and adherence to each CONSORT section were calculated. Regression analyses investigated the association between completeness of reporting, ROB, and other characteristics (quartile range, publication modalities, study protocol registration).Data SynthesisThe mean overall CONSORT adherence across studies was 65%. Studies with high ROB have less adherence than those with low ROB (?5.5%; CI, ?10.9 to 0.0). There was a 10.2% (% CI, 6.2-14.3) increase in adherence if the RCT protocol was registered. Studies published in first quartile journals displayed an overall adherence of 11.7% (% CI 17.1-6.4) higher than those published in the fourth quartile.ConclusionsReporting completeness is still suboptimal and is associated with ROB, journal impact ranking, and registration of the study protocol. Trial authors should improve adherence to the CONSORT guideline, and journal editors should adopt new strategies to improve the reporting.     

Effects of Virtual Reality Intervention on Neural Plasticity in Stroke Rehabilitation: A Systematic Review

ObjectiveTo systematically review and examine the current literature regarding the effects of virtual reality (VR)–based rehabilitation on neural plasticity changes in survivors of stroke.Data SourcesWe searched 6 bioscience and engineering databases, including Medline via EBSCO, Embase, PsycINFO, IEEE Explore, Cumulative Index of Nursing and Allied Health, and Scopus.Study SelectionWe selected studies reporting on the pre-post assessment of a VR intervention with neural plasticity measures published between 2000 and 2021.Data ExtractionTwo independent reviewers conducted study selection, data extraction, and quality assessment. They assessed methodological quality of controlled trials using the Physiotherapy Evidence Database scale and evaluated risk of bias of pre-post intervention and case studies using the National Institutes of Health Quality Assessment Tool.Data SynthesisWe included 27 studies (n=232). We rated 7 randomized-controlled trials as good quality and 2 clinical-controlled trials as moderate. Based on the risk of bias assessment, we graded 1 pre-post study and 1 case study as good quality, 1 pre-post study and 1 case study as poor, and the other 14 studies as fair. After the VR intervention, main neurophysiological findings across studies include: (1) improved interhemispheric balance; (2) enhanced cortical connectivity; (3) increased cortical mapping of the affected limb muscles; (4) the improved neural plasticity measures were correlated to the enhanced behavior outcomes; (5) increased activation of regions in frontal cortex; and (6) the mirror neuron system may be involved.ConclusionsVR-induced changes in neural plasticity for survivors of stroke. Positive correlations between the neural plasticity changes and functional recovery elucidates the mechanisms of VR-based therapeutic effects in stroke rehabilitation. This review prompts systematic understanding of the neurophysiological mechanisms of VR-based stroke rehabilitation and summarizes the emerging evidence for ongoing innovation of VR systems and application in stroke rehabilitation.     

Effect of Social Determinants of Health Interventions on Adults Living With Disabilities: A Scoping Review

ObjectiveTo investigate social determinants of health (SDoH) interventions on individual health outcomes, population health, and cost for persons in the United States over age 18 living with disabilities and receiving long-term services and supports (LTSS) in noninstitutional settings.Data SourcesA review using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted of literature from PubMed, PsycINFO, REHABDATA, and Web of Science Core Collection published between January 1997 and July 2020.Study SelectionSearch terms were based on the primary SDoH domains identified by the Centers for Medicare and Medicaid's Accountable Health Communities Model. A total of 5082 abstracts were screened based on identification criteria of persons age 18 and above living in non-institutional, community-based settings receiving LTSS.Data ExtractionDuring Level 2 review, articles were reviewed based on population focus, type of LTSS (personal assistance services, home care, adult day care, home modification, durable medical equipment, community transition services, caregiver supports and/or prevention services related to home- and community-based care), SDoH intervention and association with health outcomes, population health and/or cost. A total of 1037 abstracts underwent Level 2 review, yielding 131 publications or 1.3% for full review.Data SynthesisStudies (n=33) designed a priori to test outcomes of interventions were rated according to Grading Recommendations Assessment Development and Evaluation (GRADE) criteria. Qualifying articles that did not include interventions (n=98) were included in our summary of the literature but were not assessed by GRADE.ConclusionsThe preponderance of research surrounding SDoH and health outcomes has focused on older adults living with disabilities, and most interventions scored low or very low using GRADE criteria. Evidence is limited to the extent SDoH interventions are measured against outcomes for persons of all ages living with disabilities. Robust evaluation of models that feature SDoH interventions in partnership with community-based organizations is recommended as home and community-based care infrastructure expands in response to the American Rescue Plan Act of 2021.     

Non-pharmacological interventions for spasticity in adults: An overview of systematic reviews

ObjectivesSpasticity causes significant long-term disability-burden, requiring comprehensive management. This review evaluates evidence from published systematic reviews of clinical trials for effectiveness of non-pharmacological interventions for improved spasticity outcomes.MethodsData sources: a literature search was conducted using medical and health science electronic (MEDLINE, EMBASE, CINAHL, PubMed, and the Cochrane Library) databases for published systematic reviews up to 15th June 2017. Data extraction and synthesis: two reviewers applied inclusion criteria to select potential systematic reviews, independently extracted data for methodological quality using Assessment of Multiple Systematic Reviews (AMSTAR). Quality of evidence was critically appraised with Grades of Recommendation, Assessment, Development and Evaluation (GRADE).ResultsOverall 18 systematic reviews were evaluated for evidence for a range of non-pharmacological interventions currently used in managing spasticity in various neurological conditions. There is “moderate” evidence for electro-neuromuscular stimulation and acupuncture as an adjunct therapy to conventional routine care (pharmacological and rehabilitation) in persons following stroke. “Low” quality evidence for rehabilitation programs targeting spasticity (such as induced movement therapy, stretching, dynamic elbow-splinting, occupational therapy) in stroke and other neurological conditions; extracorporeal shock-wave therapy in brain injury; transcranial direct current stimulation in stroke; transcranial magnetic stimulation and transcutaneous electrical nerve stimulation for other neurological conditions; physical activity programs and repetitive magnetic stimulation in persons with MS, vibration therapy for SCI and stretching for other neurological condition. For other interventions, evidence was inconclusive.ConclusionsDespite the available range of non-pharmacological interventions for spasticity, there is lack of high-quality evidence for many modalities. Further research is needed to judge the effect with appropriate study designs, timing and intensity of modalities, and associate costs of these interventions.     

Measurement Properties of the Mayo-Portland Adaptability Inventory (MPAI-4) and Related Measures: A Systematic Review

ObjectiveTo assess the Mayo-Portland Adaptability Inventory—version 4 (MPAI-4) and related measures’ measurement properties and the quality of evidence supporting these results; and identify the interpretability and feasibility of the MPAI-4 and related measures.Data SourcesWe conducted a systematic review according to COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines. We searched 9 electronic databases and registries, and hand searched reference lists of included articles.Study SelectionTwo independent reviewers screened and selected all articles. From 605 retrieved articles, 48 were included.Data ExtractionTwo independent reviewers appraised the evidence quality and rated the extracted classical test theory and Rasch results from each study.Data SynthesisWe used meta-analysis and COSMIN's approach to synthesize measurement properties evidence (insufficient, sufficient), and the modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to synthesize evidence quality (very low, low, moderate, high) by diagnosis (traumatic brain injury [TBI], stroke), and setting (inpatient, outpatient). The MPAI-4 and its subscales are sufficiently comprehensible (GRADE: very low), but there is currently no other content validity evidence (relevance, comprehensiveness). The MPAI-4 and its participation index (M2PI) have sufficient interrater reliability for stroke and TBI outpatients (GRADE: moderate), whereas interrater reliability between TBI inpatients and clinicians is currently insufficient (GRADE: moderate). There is no evidence for measurement error. For stroke and TBI outpatients, the MPAI-4 and M2PI have sufficient construct validity (GRADE: high) and responsiveness (GRADE: moderate-high). For TBI inpatients, the MPAI-4 and M2PI have mixed indeterminant/sufficient construct validity and responsiveness evidence (GRADE: moderate-high). There is 1 study with mixed insufficient/sufficient evidence for each MPAI-4 adaptation (21- and 22-item MPAI, 9-item M2PI) (GRADE: low-high).ConclusionUsers can be most confident in using the MPAI-4 and M2PI in TBI and stroke outpatient settings. Future research is needed on reliability, measurement error, predictive validity, and content validity of the MPAI-4 and its related measures across populations and settings.     

Update on the Efficacy of Cognitive Rehabilitation After Moderate to Severe Traumatic Brain Injury: A Scoping Review

Objectives: To identify, categorize, and analyze the methodological issues of cognitive rehabilitation of patients with moderate to severe traumatic brain injury and its efficacy.Data SourcesPubmed and PsycINFO were searched for studies published between 2015 and 2021 using keywords for cognitive intervention and traumatic brain injury.Study SelectionTwo independent reviewers selected articles concerning cognitive rehabilitation for adults with traumatic brain injury. Of 458 studies, 97 full-text articles were assessed and 46 met the inclusion criteria.Data ExtractionData were analyzed by 1 reviewer according to criteria concerning the methodological quality of studies.Data SynthesisResults showed a large scope of 7 cognitive domains targeted by interventions, delivered mostly in individual sessions (83%) with an integrative cognitive approach (48%). Neuroimaging tools as a measure of outcome remained scarce, featuring in only 20% of studies. Forty-three studies reported significant effects of cognitive rehabilitation, among which 7 fulfilled a high methodological level of evidence.Conclusions: Advances and shortcomings in cognitive rehabilitation have both been highlighted and led us to develop methodological key points for future studies. The choice of outcome measures, the selection of control interventions, and the use of combined rehabilitation should be investigated in further studies.     

A Systematic Review of Systematic Reviews and a Pooled Meta-Analysis on Complementary and Integrative Medicine for Improving Cancer-Related Fatigue

PurposeEvidence supporting complementary and integrative medicine (CIM) for improving cancer-related fatigue (CRF) is still fragmented. This study therefore critically appraised all the systematic reviews (SRs) regarding the effectiveness of CIM in mitigating CRF in adults.MethodsA systematic review of SRs and a meta-analysis were conducted in 4 databases. The effect sizes of the included SRs were quantitatively pooled (standardized mean difference [SMD]; 95% CI) using a random-effects model. Heterogeneity was tested by using χ² (Q) tests and I² statistics.FindingsTwenty-two SRs met the inclusion criteria, and results from 20 SRs underwent meta-analysis. The pooled significant estimate of fatigue reduction was as follows: SMD, ?0.50; 95% CI, ?0.67 to ?0.32; P < 0.001. The subgroup analysis based on the type of CIM intervention revealed that the approach showing higher effects in reducing fatigue thus far is acupuncture: SMD, –0.99; 95% CI = –1.37 to –0.62, P < 0.001; I² = 84%. CIM therapies showed a significant reduction of fatigue in patients with breast cancer: SMD, –0.46; 95% CI, –0.69 to –0.23; P < 0.001; I² = 82%.ImplicationsCIM interventions showed effectiveness in reducing CRF. Subgroup analysis suggested some potential influencing, such as tumor type and specific CIM therapy factors, that require in-depth assessment in future research. Study protocol registration: PROSPERO CRD42020194254.     

Epidemiology, quality, and reporting characteristics of systematic reviews of acupuncture interventions published in chinese journals

Abstract Background: Systematic reviews (SRs) of acupuncture have become increasingly popular in China in recent years and have been published in large numbers. This review provides the first examination of epidemiological characteristics of these SRs as well as compliance with the PRISMA and AMSTAR guidelines. Objectives: The study objectives were to examine epidemiological and reporting characteristics as well as methodological quality of SRs of acupuncture published in Chinese journals. Methods: Four (4) Chinese databases were searched (CBM, CSJD, CJFD, and Wanfang Database) for SRs of Traditional Chinese Medicine, from January 1978 through to December 2010. Data were extracted into Excel spreadsheets. The PRISMA and AMSTAR checklists were used to assess reporting characteristics and methodological quality, respectively. Results: A total of 88 SRs were identified; none of the reviews had been updated. Less than one third (27.3%) were written by clinicians and one third (35.2%) were reported in specialty journals. The impact factor of 53.4% of the journals published was 0. Information retrieval was not comprehensive in more than half (59.1%) of the reviews. Less than half (36.4%) reported assessing for publication bias. Though 97.7% of the reviews used the term "systematic review" or "meta-analysis" in the title, no reviews reported a protocol and none were updated even after they had been published after 2 or more years. Conclusions: Although many SRs of acupuncture interventions have been published in Chinese journals, the reporting quality is troubling. Thus, the most urgent strategy is to focus on increasing the standard of SRs of acupuncture interventions, rather than continuing to publish them in great quantity.     

Effectiveness of Conservative Nonpharmacologic Therapies for Pain,Disability, Physical Capacity,and Physical Activity Behavior in Patients With Degenerative Lumbar Spinal Stenosis: A Systematic Review and Meta-Analysis

ObjectiveTo investigate the effectiveness of conservative nonpharmacologic therapies on pain, disability, physical capacity, and physical activity outcomes in patients with degenerative lumbar spinal stenosis (LSS).Data SourcesSystematic search of MEDLINE, EMBASE, CENTRAL, and PsycINFO from inception to November 4, 2019, without language restrictions.Study SelectionPairs of review authors independently identified randomized controlled trials published in peer-reviewed scientific journals reporting on the effects of rehabilitation interventions on pain intensity (back or leg), disability, symptom severity, physical capacity, physical activity behavior, or adverse events (secondary outcome) in adults with LSS. The search identified 1718 records; data from 21 reports of 19 trials (1432 patients) were included.Data ExtractionReview author pairs independently extracted data and assessed included studies. We assessed risk of bias with the Cochrane tool, and overall study quality with the Grading of Recommendations Assessment, Development and Evaluation classification.Data SynthesisWe pooled data using random-effects meta-analyses; treatment effects were reported as mean differences (MD) and 95% confidence intervals (CI). Directed exercise and manual therapy was superior to self-directed or group exercise for improving short-term walking capacity (MD, 293.3 m; 95% CI, 61.7-524.9 m; low-quality evidence), back pain (MD, –1.1; 95% CI, –1.8 to –0.4; moderate quality evidence), leg pain (MD, –.9; 95% CI, –0.2 to –1.5; moderate-quality evidence), and symptom severity (MD, –0.3; 95% CI, –0.4 to –0.2; low quality evidence). There is very low quality evidence that rehabilitation is no better than surgery at improving intermediate- or long-term disability. Single trials provided conflicting evidence of effectiveness for a variety of therapies.ConclusionsFor patients with LSS, there is low- to moderate-quality evidence that manual therapy with supervised exercises improves short-term walking capacity and results in small improvements in pain and symptom severity compared with self-directed or group exercise. The choice between rehabilitation and surgery for LSS is very uncertain owing to the very low quality of available evidence.
