Appraisal of quality and analysis of the similarities and differences between osteoarthritis Clinical Practice Guideline recommendations: A systematic review

OBJECTIVE

Clinical Practice Guidelines (CPGs) aim to support management of hip and knee osteoarthritis (OA), but recommendations are often conflicting and implementation is poor, contributing to evidence-to-practice gaps. This systematic review investigated the contextual and methodological factors contributing to conflicting recommendations for hip and knee OA.

METHOD

Our systematic review appraised CPGs for managing hip and knee OA in adults ≥18 years (PROSPERO CRD42021276635). We used AGREE-II and AGREE-REX to assess quality and extracted data on treatment gaps, conflicts, biases, and consensus. Heterogeneity of recommendations was determined using Weighted Fleiss Kappa (K). The relationship between (K) and AGREE-II/AGREE-REX scores was explored.

RESULTS

We identified 25 CPGs across eight countries and four international organisations. The ACR, EULAR, NICE, OARSI and RACGP guidelines scored highest for overall AGREE-II quality (83%). The highest overall AGREE-REX scores were for BMJ Arthroscopy (80%), RACGP (78%) and NICE (76%). CPGs with the least agreement for pharmacological recommendations were ESCEO and NICE (-0.14), ACR (-0.08), and RACGP (-0.01). The highest agreements were between RACGP and NICE (0.53), RACGP and ACR (0.61), and NICE and ACR (0.91). Decreased internal validity determined by low-quality AGREE scores(<60%) in editorial independence were associated with less agreement for pharmacological recommendations.

CONCLUSION

There were associations between guideline quality and agreement scores. Future guideline development should be informed by robust evidence, editorial independence and methodological rigour to ensure a harmonisation of recommendations. End-users of CPGs must recognise the contextual factors associated with the development of OA CPGs and balance these factors with available evidence.

Physiotherapy assessment and treatment of patients with tibial external fixator: a systematic scoping review

PURPOSE

To map evidence regarding physiotherapy assessment and treatment of patients with tibial external fixator (EF), and to point out literature gaps for further research.

METHODS

Systematic scoping review conducted in four databases. We included both experimental and non-experimental studies involving patients with tibial EF and outcomes of interest. We recorded study design, population, sample size, sample age, reason for EF use, type of surgery, type of EF used, instruments used for assessing function, pain, quality of life, satisfaction, psychosocial aspects, and physiotherapy treatment descriptions from included studies. We categorised data accordingly to outcomes assessed and physiotherapy treatments description.

RESULTS

Eighty-six studies were included involving 3070 patients. Causes of fixator use were traumatic conditions, acquired and congenital deformities, and non-traumatic conditions, like compartmental osteoarthritis. Function was assessed in about three-quarters of included studies, though other outcomes were not presented in most studies. Only one study described satisfactorily the physiotherapy treatment. Almost half of the studies did not provide any description of the rehabilitation process.

CONCLUSIONS

There is little evidence about the assessment of function, pain, quality of life, satisfaction, psychosocial aspects, and other outcomes in tibial EF patients. Physiotherapy treatment in these patients is poorly reported.Protocol registration: Open Science Framework: doi:10.17605/OSF.IO/UT2DA.

Reporting form and content of research priorities identified in knee osteoarthritis clinical practice guidelines: a methodological literature analysis

OBJECTIVES

Clinical practice guideline (CPG) developers conduct systematic summaries of research evidence, providing them great capacity and ability to identify research priorities. We systematically analysed the reporting form and content of research priorities in CPGs related to knee osteoarthritis (KOA) to provide a valuable reference for guideline developers and clinicians.

DESIGN

A methodological literature analysis was done and the characteristics of the reporting form and the content of the research priorities identified in KOA CPGs were summarised.

DATA SOURCES

Six databases (PubMed, Embase, China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals, Wanfang and Chinese Biomedical Literature Database) were searched for CPGs published from 1 January 2017 to 4 December 2022. The official websites of 40 authoritative orthopaedic societies, rheumatology societies and guideline development organisations were additionally searched.

ELIGIBILITY CRITERIA

We included all KOA CPGs published in English or Chinese from 1 January 2017 that included at least one recommendation for KOA. We excluded duplicate publications, older versions of CPGs as well as guidance documents for guideline development.

DATA EXTRACTION AND SYNTHESIS

Reviewers worked in pairs and independently screened and extracted the data. Descriptive statistics were used, and absolute frequencies and proportions of related items were calculated.

RESULTS

187 research priorities reported in 41 KOA CPGs were identified. 24 CPGs reported research priorities, of which 17 (41.5%) presented overall research priorities for the entire guideline rather than for specific recommendations. 110 (58.8%) research priorities were put forward due to lack of evidence. Meanwhile, more than 70% of the research priorities reflected the P (population) and I (intervention) structural elements, with 135 (72.2%) and 146 (78.1%), respectively. More than half of the research priorities (118, 63.8%) revolved around evaluating the efficacy of interventions. Research priorities primarily focused on physical activity (32, 17.3%), physical therapy (30, 16.2%), surgical therapy (27, 14.6%) and pharmacological treatment (26, 14.1%).

CONCLUSIONS

Research priorities reported in KOA CPGs mainly focused on evaluating non-pharmacological interventions. There exists considerable room for improvement for a comprehensive and standardised generation and reporting of research priorities in KOA CPGs.

Effectiveness of Rehabilitation for Osteoarthritis of the Knee: A Scoping Review of Network Meta-Analyses

BACKGROUND

 Although an increasing number of network meta-analyses have been conducted on the effectiveness of conservative therapy for knee osteoarthritis, these may have been poorly planned and executed.We aimed to review the qualities of a comprehensive set of network meta-analyses on rehabilitation therapies for knee osteoarthritis and provide an overview of the effectiveness of each therapy.

METHODS

The eligibility criteria were as follows: (i) conservative rehabilitation was the primary treatment in the intervention group, (ii) included patients were diagnosed with knee osteoarthritis, and (iii) patient groups were aged ≤75 years, and rehabilitation interventions comprised exercise, orthotic, or physical therapies or patient education. Two independent reviewers screened the titles and abstracts of the identified records and selected the eligible reviews; their full texts were further assessed for eligibility. Then, a checklist derived from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension statement for the reporting of systematic reviews incorporating network meta-analyses of healthcare Interventions was used to validate the completeness of the reporting of each network meta-analysis. Furthermore, the statistical and outcome data regarding the quality of life, knee joint function and pain, adverse events, and physical functions were extracted using a customized spreadsheet.

RESULTS

Overall, 2701 titles and abstracts were screened, and eight network meta-analyses were ultimately selected. Nearly all reviews adequately addressed the PRISMA extension checklist, and the completeness of reporting was adequate; therefore, all expected information could be extracted. However, the methodology used to confirm the transitivity assumption was insufficient in many reviews. The following interventions were effective in reducing pain and improving physical function: (i) strengthening, flexibility, aerobic, and mind-body exercises, (ii) pulsed ultrasound, (iii) focused and radial extracorporeal shockwave therapy, and (iv) continuous ultrasound. The following interventions were effective in improving the quality of life: (i) strengthening, (ii) mixed, and (iii) mind-body exercises.

CONCLUSIONS

Our results suggested that exercise therapies, including muscle-strengthening, aerobic, flexibility, and mind-body exercises, are likely to be effective for pain relief and functional improvement in knee osteoarthritis. This may be the first review to provide a comprehensive perspective for considering priorities for future rehabilitation interventions for knee osteoarthritis.

Effects of mind-body exercise on knee osteoarthritis: a systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

To evaluate the effect of mind-body exercise on improving knee osteoarthritis (KOA) and thereby informing osteoarthritis exercise rehabilitation.

METHODS

The China National Knowledge Infrastructure (CNKI), Wanfang, PubMed/Medline, Cochrane Library, Web of Science, EBSCO, Embase, Scopus, and ProQuest databases were searched to identify randomized controlled trials (RCTs) that involved tai chi, yoga, and baduanjin interventions for KOA. The search period ranged from inception to October 25, 2022. The methodological quality of the included studies was evaluated by the Cochrane risk of bias assessment tool, and the included data were statistically analyzed and plotted using Review Manager 5.3 and Stata 14.0 software.

RESULTS

We included 17 articles with a total of 1122 patients. Compared with the control group, mind-body exercise significantly improved patient pain (standardized mean difference (SMD) = -0.65, 95% confidence interval (CI) [-0.87, -0.42], p < 0.00001), stiffness (SMD = -0.75, 95% CI [-1.05, -0.45], p < 0.00001), physical function (SMD = -0.82, 95% CI [-1.03, -0.62], p < 0.00001), mental health (SMD = 0.31, 95% CI [0.11, 0.51], p = 0.002), and depression (SMD = -0.32, 95% CI [-0.50, -0.15], p = 0.0003). In terms of motor ability, mind-body exercise significantly increased the 6-min walking distance (SMD = 18.45, 95% CI [5.80, 31.10], p = 0.004) and decreased timed up and go test time (SMD = -1.15, 95% CI [-1.71, -0.59], p < 0.0001).

CONCLUSIONS

The current study showed that mind-body exercise is safe and effective for KOA patients. However, given the methodological limitations of the included studies, additional high-quality evidence is needed to support the conclusions of this study.

Efficacy of acupuncture combined with active exercise training in improving pain and function of knee osteoarthritis individuals: a systematic review and meta-analysis

OBJECTIVE

To conduct a systematic review and meta-analysis to investigate the clinical efficacy of acupuncture combined with active exercise training in improving pain and function of knee osteoarthritis (KOA) individuals.

DATA SOURCES

PubMed, EMBASE, The Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wan Fang Data, Technology Periodical Database and China Biology Medicine were searched from their inceptions to April 5, 2023.

REVIEW METHODS

We analyzed trials of acupuncture combined with active exercise training for KOA. The included studies were of high quality (Jadad ≥ 4) and RCTs. Study selection, data extraction, risk of bias and quality assessment were independently performed by two reviewers. We performed systematic analyses based on different outcome measures, including total efficiency rate, visual analogue scale (VAS), the Western Ontario and Mcmaster Universities Osteoarthritis Index (WOMAC), the Lysholm Knee Scale (LKS) and range of motion (ROM). We used Review Manager 5.3 and Stata/MP 14.0 to analyze the data. And it was verified by trial sequence analysis (TSA). If I2 > 50% and p < 0.05, we performed sensitivity analysis and subgroup analysis to find the source of heterogeneity. Publication bias was studied by funnel plot and Egger's test was used to verify it.

RESULTS

Full 11 high-quality studies (Jadad ≥ 4) including 774 KOA individuals were included in this review for meta-analysis. The results showed that acupuncture combined with active exercise training (combined group) was superior to the acupuncture group in improving the total effective rate [RR = 1.13, 95%CI (1.05, 1.22), I2 = 0%, P = 0.70], reducing the pain level (VAS) [MD = - 0.74, 95%CI (- 1.04,  - 0.43), I2 = 68%, P < 0.05], improving knee joint function (WOMAC) [MD =  - 6.97, 95%CI (- 10.74, - 3.19), I2 = 76%, P < 0.05] and improving joint range of motion (ROM) [MD = 6.25, 95%CI (2.37, 10.04), I2 = 0%, P = 0.71]. Similarly, the combined group showed significant improvements in the total effective rate [RR = 1.31, 95% CI (1.18, 1.47), I2 = 48%, P = 0.10], pain (VAS) [MD = 1.42, 95% CI (- 1.85, - 1.00), I2 = 65%, P = 0.02] and knee function (WOMAC) [MD = 7.05, 95% CI (- 11.43, - 2.66), I2 = 86%, P < 0.05] compared with the non-acupuncture group.

CONCLUSION

The combined effect of all studies showed significant benefits of acupuncture combined with active exercise training in improving the total effective rate, reducing pain, promoting recovery of knee function and expanding range of motion. However, some evaluation indicators are highly subjective and need to be further confirmed by more objective and evidence-based high-quality RCTs in future.

Multidisciplinary Rehabilitation after Hyaluronic Acid Injections for Elderly with Knee, Hip, Shoulder, and Temporomandibular Joint Osteoarthritis

Osteoarthritis (OA) is a prevalent degenerative joint condition characterized by cartilage deterioration, joint inflammation, and functional limitations, particularly impacting the elderly population. Rehabilitation and hyaluronic acid (HA) injections are common therapeutic approaches routinely used in clinical practice, but their synergistic potential is far from being fully characterized. Thus, the aim of this narrative review was to elucidate the multilevel benefits and synergies of integrating these two approaches in multidisciplinary OA rehabilitation. This narrative review follows the scale for the assessment of narrative review articles (SANRA) criteria and involves a comprehensive literature search from July to August 2023. Two independent reviewers screened studies, including those involving human subjects with OA, rehabilitation strategies, and outcomes following HA injection, published in English. Results: HA injections might improve joint biomechanics, reducing friction, absorbing shocks, and potentially regulating inflammation. Rehabilitation plays a pivotal role in strengthening muscles, increasing the range of motion, and enhancing overall function. Optimizing rehabilitation following HA injection might provide additional benefits in joint health. OA management requires a multidisciplinary approach integrating HA injections, rehabilitation, and personalized care. Challenges in patient adherence and healthcare resources currently exist, but emerging technologies offer opportunities to enhance patient engagement and monitoring optimizing sustainability and outcomes of patients with knee, hip, shoulder, and temporomandibular joint OA.

Adapting a Clinical Practice Guideline for Management of Patients with Knee and Hip Osteoarthritis by Hong Kong Physiotherapists

Knee and hip osteoarthritis are common disabling conditions globally. Although numerous international clinical practice guidelines exist to guide physiotherapy management, not all recommendations issued from these guidelines can be translated to other contexts without considering the cultural acceptability and clinical implementability of targeted countries. Because the ADAPTE framework provides a robust methodology to adapt guidelines to the local context, this study used its methodology to adapt high-quality guideline recommendations to promote optimal physiotherapy care for knee and hip osteoarthritis in Hong Kong. The ADAPTE framework was used and modified to complete the adaptation process. International clinical practice guidelines were identified from eight guideline clearinghouses and six electronic databases. Two independent reviewers critically appraised the eligible guidelines using the AGREE II tool. We extracted and tabulated recommendations from high-quality guidelines. A voting-based consensus among interdisciplinary experts was conducted to decide on suitable recommendations for the Hong Kong context and whether there was a need to modify them. Pertinent recommendations were then translated into the traditional Chinese language. Our team members suggested modifying four tools and adding one to explore the patient's feedback on the recommendations, to the ADAPTE framework. The adaptation was performed on three high-quality guidelines. We adapted 28 and 20 recommendations for treating knee and hip osteoarthritis, respectively. We recommend a multimodal treatment for managing knee and hip osteoarthritis. Land- and aquatic-based exercises, patient education, and self-management were strongly recommended for patients with knee osteoarthritis. Land- and aquatic-based exercises were strongly recommended for patients with hip osteoarthritis. This is the first adaptation study in Hong Kong. It provides guidance to local physiotherapists on managing patients with knee and hip osteoarthritis. Future studies should test the effectiveness of implementing this adapted guideline to improve local physiotherapy care in Hong Kong.

Recommendations for the management of hip and knee osteoarthritis: A systematic review of clinical practice guidelines

OBJECTIVES

Guideline adherence for hip and knee osteoarthritis management is often poor, possibly related to the quality and/or inconsistent recommendations. This systematic review of hip and knee osteoarthritis guidelines aimed to appraise the quality and consistency in recommendations across higher-quality guidelines.

METHODS

Eight databases, guideline repositories, and professional associations websites were searched on 27/10/2022. Guideline quality was appraised using the Appraisal of Guidelines for Research and Evaluation II (AGREE II tool) (six domains). Higher quality was defined as scoring ≥60% for domains 3 (rigour of development), 6 (editorial independence), plus one other. Consistency in recommendations across higher-quality guidelines was reported descriptively. This review was registered prospectively (CRD42021216154).

RESULTS

Seven higher-quality and 18 lesser-quality guidelines were included. AGREE II domain scores for higher-quality guidelines were > 60% except for applicability (average 46%). Higher-quality guidelines consistently recommended in favour of education, exercise, and weight management and non-steroidal anti-inflammatory drugs (hip and knee), and intra-articular corticosteroid injections (knee). Higher quality guidelines consistently recommended against hyaluronic acid (hip) and stem cell (hip and knee) injections. Other pharmacological recommendations in higher-quality guidelines (e.g., paracetamol, intra-articular corticosteroid (hip), hyaluronic acid (knee)) and adjunctive treatments (e.g., acupuncture) were less consistent. Arthroscopy was consistently recommended against in higher-quality guidelines. No higher-quality guidelines considered arthroplasty.

CONCLUSION

Higher-quality guidelines for hip and knee osteoarthritis consistently recommend clinicians implement exercise, education, and weight management, alongside consideration of Non-Steroidal Anti-Inflammatory Drugs and intra-articular corticosteroid injections (knee). Lack of consensus on some pharmacological options and adjunctive treatments creates challenges for guideline adherence. Future guidelines must prioritise providing implementation guidance, considering consistently low applicability scores.

Identifying strategies that support equitable person-centred osteoarthritis care for diverse women: content analysis of guidelines

INTRODUCTION

Women are disproportionately impacted by osteoarthritis (OA) but less likely than men to access early diagnosis and management, or experience OA care tailored through person-centred approaches to their needs and preferences, particularly racialized women. One way to support clinicians in optimizing OA care is through clinical guidelines. We aimed to examine the content of OA guidelines for guidance on providing equitable, person-centred care to disadvantaged groups including women.

METHODS

We searched indexed databases and websites for English-language OA-relevant guidelines published in 2000 or later by non-profit organizations. We used manifest content analysis to extract data, and summary statistics and text to describe guideline characteristics, person-centred care (PCC) using a six-domain PCC framework, OA prevalence or barriers by intersectional factors, and strategies to improve equitable access to OA care.

RESULTS

We included 36 OA guidelines published from 2003 to 2021 in 8 regions or countries. Few (39%) development panels included patients. While most (81%) guidelines included at least one PCC domain, guidance was often brief or vague, few addressed exchange information, respond to emotions and manage uncertainty, and none referred to fostering a healing relationship. Few (39%) guidelines acknowledged or described greater prevalence of OA among particular groups; only 3 (8%) noted that socioeconomic status was a barrier to OA care, and only 2 (6%) offered guidance to clinicians on how to improve equitable access to OA care: assess acceptability, availability, accessibility, and affordability of self-management interventions; and employ risk assessment tools to identify patients without means to cope well at home after surgery.

CONCLUSIONS

This study revealed that OA guidelines do not support clinicians in caring for diverse persons with OA who face disadvantages due to intersectional factors that influence access to and quality of care. Developers could strengthen OA guidelines by incorporating guidance for PCC and for equity that could be drawn from existing frameworks and tools, and by including diverse persons with OA on guideline development panels. Future research is needed to identify multi-level (patient, clinician, system) strategies that could be implemented via guidelines or in other ways to improve equitable, person-centred OA care.

PATIENT OR PUBLIC CONTRIBUTION

This study was informed by a team of researchers, collaborators, and thirteen diverse women with lived experience, who contributed to planning, and data collection, analysis and interpretation by reviewing study materials and providing verbal (during meetings) and written (via email) feedback.

Chinese guidelines for the rehabilitation treatment of knee osteoarthritis: An CSPMR evidence-based practice guideline

BACKGROUND

Knee osteoarthritis (KOA) is the most common degenerative joint disease in China, causing a huge economic burden on patients, families, and society. Standardized KOA rehabilitation treatment is an important means to prevent and treat the disease and promote the development of high-quality medical services. This guideline is updated on the basis of the 2016 and 2019 editions.

METHODS

Clinical questions regarding rehabilitation assessment and treatment were selected through clinical questions screening and deconstruction, and multiple rounds of Delphi questionnaire consultation. The International Classification of Functioning, Disability and Health (ICF) was used as the theoretical framework, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method was used to grade the quality of evidence and recommendations.

RESULTS

The reporting of this guideline followed the standard of Reporting Items for Practice Guidelines in Healthcare (RIGHT). Taking into account patients' preferences and values and the needs of Chinese clinical practice, a total of 11 clinical questions and 28 recommendations were established. The clinical questions were grouped into two categories: KOA assessment (body function, body structure, activity and participation, quality of life, and environmental factors and clinical outcomes assessment, resulting in 9 recommendations) and KOA treatment (health education, therapeutic exercise, therapeutic modalities, occupational therapy, assistive devices, and regenerative rehabilitation approaches, resulting in 19 recommendations).

CONCLUSION

This is the first evidence-based guideline for KOA rehabilitation in China utilizing the ICF framework. This guideline provides key guidance for developing systematic, standardized, and precise rehabilitation protocols for KOA across various healthcare settings.

Core Recommendations for Osteoarthritis Care: A Systematic Review of Clinical Practice Guidelines

OBJECTIVE

To evaluate the quality of clinical practice guidelines (CPGs) for interventions in management of osteoarthritis (OA) and to provide a synthesis of high-quality CPG recommendations.

METHODS

Five databases (OvidSP Medline, Cochrane, Cumulative Index to Nursing and Allied Health Literature [CINAHL], Embase, and the Physiotherapy Evidence Database [PEDro]) and 4 online guideline repositories were searched. CPGs for the management of OA were included if they were 1) written in English and published from January 2015 to February 2022, focused on adults age ≥18 years, and met the criteria of a CPG as defined by the Institute of Medicine; and 2) were rated as high quality on the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. CPGs for OA were excluded if they were available via institutional access only, only addressed recommendations for the system/organization of care and did not include interventional management recommendations, and/or included other arthritic conditions.

RESULTS

Of 20 eligible CPGs, 11 were appraised as high quality and included in the synthesis. Of interest were the hip, knee, hand, and glenohumeral joints and/or polyarticular OA. Consistent recommendations were that care should be patient centered and include exercise, education, and weight loss (where appropriate). Nonsteroidal antiinflammatory drugs and surgical interventions were recommended for disabling OA that had not improved with nonsurgical care. Hand orthoses should be recommended for patients with hand OA.

CONCLUSION

This synthesis of high-quality CPGs for OA management offers health care providers with clear, simple guidance of recommended OA care to improve patient outcomes.

Autologous micro-fragmented adipose tissue in the treatment of atherosclerosis patients with knee osteoarthritis in geriatric population: A systematic review and meta-analysis

BACKGROUND

Atherosclerosis and osteoarthritis are closely related. However, no high-quality studies have investigated the potential of micro-fragmented adipose tissue to treat patients with atherosclerosis accompanied by osteoarthritis.

METHODS

PubMed, Embase, the Cochrane Library, Web of Science, China National Knowledge Infrastructure, WANFANG DATA, and CQVIP were searched for potentially eligible studies published before October 13, 2022. Due to the statistical limitations of the existing relevant literature, it is not possible to make direct statistics on the patients with osteoarthritis accompanied by atherosclerosis treated by micro-fragmented adipose tissue. The primary outcome consisted of two parts: 1) Correlation between atherosclerosis and osteoarthritis; 2) Scores of the Knee injury and Osteoarthritis Outcome Score (KOOS). And secondary outcomes were pain assessed by visual analog scale (VAS) or numeric rating scale (NRS), quality of life (QoL) (assessed using tools apart from the KOOS), and adverse events (AEs). Random meta-analysis was conducted using STATA 14.0.

RESULTS

Nineteen studies were included. The metaanalysis evidenced a positive association between atherosclerosis and osteoarthritis (OR 1.17, CI 1.01-1.36). The mean absolute difference in KOOS subscale scores between pre- and post-treatment (mean with 95% confidence interval [CI]) was 19.65 (13.66, 25.63), 14.20 (4.64, 23.76), 19.95 (13.02, 26.89), 25.23 (14.80, 35.66), and 26.01 (13.68, 38.35) for pain, symptoms, activities of daily living (ADL), sports/recreation, and quality-of-life (QOL), respectively. The mean differences in VAS, resting VAS, activity VAS, and NRS between pre- and post-treatment was -8.24 (-10.66, -5.82), -3.61 (-4.49, -2.72), -4.17 (-4.89, -3.44), and -2.17 (-4.06, and -0.28), respectively. The mean difference in score of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), EQ-5D, and University of California in Los Angeles (UCLA) between pre- and post-treatment was -24.81 (-40.80, -8.82), 0.07 (0.02, 0.12), and 0.30 (-0.42, 1.02), respectively. The mean difference in Tegner score and the International Knee Documentation Committee (IKDC) score between pre- and post-treatment was 0.67 (-0.62, 1.97) and 13.70 (6.35, 21.04), respectively. The use of micro-fragmented adipose tissue was associated with risk of bruising, bleeding, hematoma, drainage, infection, soreness, swelling, pain, and stiffness in harvest and injection sites.

CONCLUSION

Atherosclerosis and osteoarthritis share common risk factors and comorbidity. And the use of micro-fragmented adipose tissue may benefit for improving symptoms of knee osteoarthritis accompanied by atherosclerosis although may lead to some mild adverse events. Randomized controlled trials with long-term follow-up are necessary for further evaluation because many limitations of this meta-analysis cannot be ignored.

Quality indicators for osteoarthritis pain management in the primary care setting

BACKGROUND

Development of valid and feasible quality indicators (QIs) is needed to track quality initiatives for osteoarthritis pain management in primary care settings.

METHODS

Literature search identified published guidelines that were reviewed for QI extraction. A panel of 14 experts was assembled, including primary care physicians, rheumatologists, orthopedic surgeons, pain specialists, and outcomes research pharmacists. A screening survey excluded QIs that cannot be reliably extracted from the electronic health record or that are irrelevant for osteoarthritis in primary care settings. A validity screening survey used a 9-point Likert scale to rate the validity of each QI based on predefined criteria. During expert panel discussions, stakeholders revised QI wording, added new QIs, and voted to include or exclude each QI. A priority survey used a 9-point Likert scale to prioritize the included QIs.

RESULTS

Literature search identified 520 references published from January 2015 to March 2021 and 4 additional guidelines from professional/governmental websites. The study included 41 guidelines. Extraction of 741 recommendations yielded 115 candidate QIs. Feasibility screening excluded 28 QIs. Validity screening and expert panel discussion excluded 73 QIs and added 1 QI. The final set of 15 prioritized QIs focused on pain management safety, education, weight-management, psychological wellbeing, optimizing first-line medications, referral, and imaging.

CONCLUSION

This multi-disciplinary expert panel established consensus on QIs for osteoarthritis pain management in primary care settings by combining scientific evidence with expert opinion. The resulting list of 15 prioritized, valid, and feasible QIs can be used to track quality initiatives for osteoarthritis pain management.

Examining the influence of pain neuroscience education followed by a Pilates exercises program in individuals with knee osteoarthritis: a pilot randomized controlled trial

BACKGROUND

Knee osteoarthritis (OA) is a multifactorial form of rheumatic condition contributing to physical and psychological factors. Treatments have been provided solely and often compared with each other. An alternative view is that combined treatments addressing physical and psychological factors may result in more benefits. This study aimed to investigate the effect of pain neuroscience education (PNE) followed by Pilates exercises (PEs) in participants with knee OA, compared to PE alone.

METHODS

In this two-arm assessor-blind pilot randomized controlled trial, fifty-four community-dwelling adults with knee OA were randomly assigned to the PNE followed by PEs and PEs groups (27 in each group). The study was conducted between early July 2021 and early March 2022 at the university's health center. Primary outcomes were Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) subscales of pain and physical limitation and secondary outcomes were Pain Catastrophizing Scale, Tampa Scale for Kinesiophobia, Pain Self-Efficacy Questionnaire, and Timed "Up & Go" test covering function. The primary and secondary outcomes were measured at baseline and eight weeks post-treatment. A general linear mixed model was used for between-group comparison with a statistical significance level of 0.05.

RESULTS

Significant within-group differences were observed in all outcomes in both groups at post-treatment. There were no statistically between-group differences in pain (adjusted mean difference: -0.8; 95% CI -2.2 to 0.7; p = 0.288), physical limitation (adjusted mean difference: -0.4; 95% CI -4 to 3.1; p = 0.812) and function (adjusted mean difference: -0.8; 95% CI -1.8 to 0.1; p = 0.069) at eight weeks. For pain catastrophizing (adjusted mean difference: -3.9; 95% CI -7.2 to -0.6; p = 0.021), kinesiophobia (adjusted mean difference: -4.2; 95% CI -8.1 to -0.4; p = 0.032), and self-efficacy (adjusted mean difference: 6.1; 95% CI 0.7 to 11.5; p = 0.028) statistically between-group improvements were observed favoring PNE followed by PEs group after the treatment.

CONCLUSIONS

Combining PNE with PEs could have superior effects on psychological characteristics but not on pain, physical limitation, and function, compared to PEs alone. This pilot study emphasizes the need to investigate the combined effects of different interventions.

Rehabilitation interventions in osteoarthritis

The goals of the management of osteoarthritis (OA) are to relieve joint pain and stiffness, maintain or increase joint mobility and stability, improve activities and participation, and enhance quality of life. The first step in the management is to make a comprehensive holistic assessment to understand the impact of the disease on the individual. Then, an individualized management plan can be set via a shared-decision making process between the patient and the clinician taking into account all components of functioning affected by the disease. Rehabilitation interventions serve as the basis of OA management whereas pharmacological modalities are usually administered for additional symptom control. This study aimed to overview the rehabilitation interventions used for people with OA with an update of the recent evidence. First, core management approaches that include patient education, physical activity and exercises, and weight loss were addressed; then adjunctive treatments including biomechanical interventions (e.g. orthoses, assistive devices) and physical modalities were overviewed.

Effect of Pain Neuroscience Education with Conventional Physiotherapy via Telerehabilitation on Pain Catastrophizing and Function in Patients with Osteoarthritis Knee: A Randomized Controlled Trial

Aim

By explaining to the patient the biological processes underneath their pain condition, pain neuroscience education (PNE) is a form of educational intervention that aims to relieve pain and impairment.

Materials and Methods

Patients with knee osteoarthritis (OA) referred to outpatient physiotherapy clinic in India during August 2021 to June 2022 were asked to participate. Out of the eligible patients, 35 were randomly assigned to PNE group and 35 to the control group. Self-reports of Pain Catastrophizing Scale (PCS), Patient Specific Function Scale (PSFS), and Numerical Pain Rating Scale (NPRS) were recorded at baseline (T1) and at 2 weeks (T2).

Results

After 2 weeks of follow-up, all the three outcome measures were found to be significant in the PNE group. The results of the unpaired t-test revealed statistically significant result posttest for PCS (mean difference 11.4) and NPRS (mean difference 1.20). There was no mean difference found in the patient function (PSFS) between groups.

Conclusion

The results suggest that adding a program of PNE to conventional physiotherapy exercises led to a greater reduction in pain catastrophization, patient-specific function, and pain intensity rather than conventional physiotherapy alone in patients with knee OA at 2 weeks' follow-up.

Effect of an Integrated Physiotherapy Protocol on Knee Osteoarthritis Patients: A Preliminary Study

BACKGROUND

Exercise therapy can potentially relieve symptoms and improve functional status of the knee osteoarthritis population. Despite the proved practical benefits, there is no standard, comprehensive physiotherapeutic protocol available targeting the physical and physiological impairment cluster associated with disease. Osteoarthritis is a whole joint disease, affecting joint cartilage, ligaments, menisci and joint associated muscles, from variable pathophysiological processes. Hence, there is a need to develop a physiotherapy protocol to address the multi-structural physical, physiological and functional impairments associated with the disease.

OBJECTIVE

The objective of the present study is to evaluate the efficacy of designed, therapist supervised, patient education, progressive resistance exercises, passive stretching exercises, soft tissue manipulation, muscle energy technique, Maitland mobilization, aerobic exercise, and neuromuscular training physiotherapy protocol on pain, disability, balance, and physical functional performance in knee osteoarthritis patients.

METHODOLOGY

The preliminary study was conducted on a (n = 60) sample of convenience. The samples were randomly allocated into two study groups, intervention, and control group. The control group was advised on a basic home program. On the other hand, the treatment of the intervention group was designed with a therapist supervised Physiotherapy Protocol. The outcome variables studied were the Visual Analogue Scale, Modified WOMAC Scale, Timed Up and Go Test, Functional Reach Test, 40 m Fast Paced Walk Test, Stair Climb Test, 30 s Chair Stand Test.

RESULTS

The results of the study revealed a significant improvement among most of the studied outcome measures in the intervention group, hence the designed supervised physiotherapy protocol was found effective in relieving multiple physiological impairments associated with this whole joint disease.

Quality of clinical practice guidelines relevant to rehabilitation of knee osteoarthritis: A systematic review

Objective

This systematic review summarized the rehabilitation recommendations for treating and managing knee osteoarthritis (OA) in practice guidelines and evaluated their applicability and quality using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument.

Data Sources

PubMed, the Cochrane Library, EMBASE, CINAHL, PEDro, Guideline central, Guideline International Network and Agency for Healthcare Research and Quality (AHRQ) were used to search for relevant studies published between 1 January 2008 and 31 May 2022.

Methods

AGREE II was used to evaluate the included guidelines quality, SPSS 25.0 statistical software was used for data analysis, and the intra-group correlation coefficient value was calculated to verify the consistency between the raters. The two-way random effects model was used to calculate concordance scores, and each domain's total scores were calculated. Additionally, the median and interquartile range for domain and total scores were calculated.

Results

Twenty-four guidelines recommending knee OA rehabilitation were included. Inter-rater consistency evaluation ranged from 0.62 to 0.90. The domains where the guideline's overall and rehabilitation parts scored highest and lowest were scope and purpose (domain 1) and applicability (domain 5), respectively. The highly recommended rehabilitation opinions included aerobic exercise programs (21/24), weight control (16/24), self-education and management (16/24), gait/walking aids (7/24), and tai chi (6/24). However, the orthopedic insole and hot/cold therapy roles remain controversial.

Conclusion

The clinical practice guidelines' overall quality for knee OA rehabilitation is good; however, the applicability is slightly poor. Therefore, we should improve the promoting factors and hindering factors, guideline application recommendations, tools, and resources when developing relevant guidelines.

Effects of computer-aided rowing exercise systems on improving muscle strength and function in older adults with mild knee osteoarthritis: a randomized controlled clinical trial

Background

Osteoarthritis (OA) is common in aged adults and can result in muscle weakness and function limitations in lower limbs. Knee OA affects the quality of life in the elderly. Technology-supported feedback to achieve lower impact on knee joints and individualized exercise could benefit elderly patients with knee OA. Herein, a computer-aided feedback rowing exercise system is proposed, and its effects on improving muscle strength, health conditions, and knee functions of older adults with mild knee OA were investigated.

Methods

Thirty-eight older adults with mild knee OA and satisfying the American College of Rheumatology (ACR) clinical criteria participated in this randomized controlled clinical trial. Each subject was randomly assigned to a computer-aided rowing exercise (CRE) group (n = 20) or a control group (CON) (n = 18) that received regular resistance exercise programs two times per week for 12 weeks. Outcome measurements, including the Western Ontario and MacMaster Universities (WOMAC), muscle strength and functional fitness of the lower limbs, were evaluated before and after the intervention.

Results

Participants’ functional fitness in the CRE group exhibited significantly higher adjusted mean post-tests scores, including the WOMAC (p = 0.006), hip abductors strength (kg) (MD = 2.36 [1.28, 3.44], p = 5.67 × 10^–5), hip adductors strength (MD = 3.04 [1.38, 4.69], p = 0.001), hip flexors strength (MD = 4.01 [2.24, 5.78], p = 6.46 × 10⁻⁵), hip extensors strength (MD = 2.88 [1.64, 4.12], p = 4.43 × 10⁻⁵), knee flexors strength (MD = 2.03 [0.66, 3.41], p = 0.005), knee extensors strength (MD = 1.80 [0.65, 2.94], p = 0.003), and functional-reach (cm) (MD = 3.74 [0.68, 6.80], p = 0.018), with large effect sizes (η² = 0.17–0.42), than those in the CON group after the intervention.

Conclusions

Older adults with knee OA in the CRE group exhibited superior muscle strength, health conditions, and functional fitness improvements after the 12-week computer-aided rowing exercise program than those receiving the conventional exercise approach.

Trial registration

The Institutional Review Board of the Taipei Medical University approved the study protocol (no. N201908020, 27/05/2020) and retrospectively registered at ClinicalTrials.gov (trial registry no. NCT04919486, 09/06/2021).

Is high intensity laser therapy more effective than other physical therapy modalities for treating knee osteoarthritis? A systematic review and network meta-analysis

Background

The use of physical therapy modalities, especially high intensity laser therapy (HILT), for individuals with knee osteoarthritis (KOA) is still controversial.

Objective

To compare the effects of HILT to other physical therapy modalities on symptoms and function in individuals with KOA.

Methods

Six databases (PubMed, Embase, Cochrane Library, Web of Science, EBSCO, and PEDro) were searched in March 2022. Included studies were randomized controlled trials involving HILT conducted on individuals with KOA. The end-trial weighted mean difference (WMD) and standard deviations (SD) with 95% confidence intervals (CI) were analyzed.

Results

Ten studies with 580 participants were obtained, of which nine were included in the final network meta-analysis. In terms of relieving pain, HILT demonstrated the highest probability of being among the most effective treatments, with surface under the cumulative ranking (SUCRA) = 100%, and compared to a control (placebo laser or exercise or a combination of both) on the visual analog scale (VAS) for pain it demonstrated significant benefits (WMD 1.66, 95% CI 1.48–1.84). For improving self-reported function, as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total scores, the HILT SUCRA value led with 98.9%. When individuals with KOA were treated by HILT, the improvement in stiffness was statistically significant (WMD 0.78, 95% CI 0.52–1.04) but the amount of improvement was smaller than the minimal clinically important difference (MCID).

Conclusion

The current evidence suggests that HILT may be more effective than other physical therapy modalities for improving pain and function in individuals with KOA. For improving stiffness, however, it may not be clinically effective.

Wnt3a knockdown promotes collagen type II expression in rat chondrocytes

Osteoarthritis (OA) is a chronic condition caused by cartilage degradation, and there are currently no effective methods for preventing the progression of this disease; gene therapy is a relatively novel method for treating arthritis. Decreased collagen type II (Col2) expression within the cartilage matrix is an important factor for the development of OA, and Wnt3a serves a significant role in cartilage homeostasis. The present study assessed whether Wnt3a knockdown promoted Col2 expression in chondrocytes. Lentivirus-introduced small interfering RNA was used to knock down the expression of Wnt3a in primary rat chondrocytes, and then IL-1β treatment was used to establish an OA chondrocyte model. The expression of target genes (Wnt3a, Col2, MMP-13 and β-catenin) was analyzed using reverse transcription-quantitative PCR, western blotting and immunocytochemistry. There was significantly less MMP-13 and β-catenin expression in the Wnt3a knockdown cells compared with the other controls. Col2 expression was significantly higher in the Wnt3a-knockdown cells compared with the control cells, indicating that knockdown of Wnt3a may promote Col2 expression. Consequently, Wnt3a was indicated to be an important factor in cartilage homeostasis, and Wnt3a knockdown may serve as a novel method for OA therapy.

Role and Effectiveness of Intra-articular Injection of Hyaluronic Acid in the Treatment of Knee Osteoarthritis: A Systematic Review

Osteoarthritis (OA) is a degenerative joint disease that causes persistent joint pain and stiffness of mainly the large peripheral weight-bearing joints. It is a leading cause of functional disability and poor quality of life. Various modalities of therapy are recommended by different research organizations at different stages of OA including non-pharmacological, pharmacological, and surgical interventions. Intra-articular injections of hyaluronic acid (HA) is widely used for over three decades in the treatment of OA. However controversies exist regarding its safety and efficacy, the number of injections and courses, type of preparation, duration of its effects, and combining it with other drugs or molecules. This study aimed to review the most recent data available in the published literature to address these.

Electronic databases like Medline, Embase, ProQuest, and Google Scholar were searched for articles using keywords, intraarticular injections, hyaluronic acid, and osteoarthritis knee. The review was carried out as per PRISMA guidelines.

Thirty-eight randomized control trials (RCTs) investigating the efficacy and safety of intra-articular injection of HA were included in the systematic review. Out of the 38 studies, 22 (57.9%) were double-blind, eight (21%) single-blind, three (7.9%) non-blind, four (10%) with simple randomization, and one (2.7%) was open-labeled. Total 5,025 patients were included in these studies. The mean age of the patients was 60.28 years and the osteoarthritis grade of the knee joint was 1 to 3. HA was studied as a test preparation in 19 (50%) while in another 19 (50%) it was studied as a control. In 24 (63.2%) studies, HA was used as high molecular weight preparation in eight (21%) as low molecular weight preparation while in six studies the information was not available. HA was used as a standalone preparation in 31 studies, in two studies it was injected with platelet-rich plasma (PRP) and with either low-level laser therapy (LLLT), triamcinolone (TA), betamethasone (CS), poly deoxyribonucleotide (PDRN) or dexamethasone (DX) in one study each. In the majority of the studies, HA was given as a single injection (52.6% studies) or weekly three injections (28.9% studies). In 13.2 %, it was given as weekly 5 injections and in 5.3% as weekly two injections.

IA-HA injections have a limited role in the treatment of knee osteoarthritis in those patients who do not have sufficient pain relief with topical or oral medication and physical therapy. It is safe and effective except for minor side effects such as local pain and swelling lasting for a few days. Severe allergic reactions are extremely rare. They provide adequate pain relief and functional improvement for up to six months irrespective of a number of injections and type of preparations used. The combination formulations with corticosteroids or PRP or MSCs show better results than HA alone. Combining HA with newer molecules such as peptides or diclofenac for sustained and disease-modifying effects requires more studies in the future.

Effects of physical exercise and body weight on disease-specific outcomes of people with rheumatic and musculoskeletal diseases (RMDs): systematic reviews and meta-analyses informing the 2021 EULAR recommendations for lifestyle improvements in people with RMDs

BACKGROUND

A European League Against Rheumatism (EULAR) taskforce was convened to develop recommendations for lifestyle behaviours in rheumatic and musculoskeletal diseases (RMDs). This paper reviews the literature on the effects of physical exercise and body weight on disease-specific outcomes of people with RMDs.

METHODS

Three systematic reviews were conducted to summarise evidence related to exercise and weight in seven RMDs: osteoarthritis, rheumatoid arthritis, systemic lupus erythematosus, axial spondyloarthritis (axSpA), psoriatic arthritis, systemic sclerosis and gout. Systematic reviews and original studies were included if they assessed exercise or weight in one of the above RMDs, and reported results regarding disease-specific outcomes (eg, pain, function, joint damage). Systematic reviews were only included if published between 2013-2018. Search strategies were implemented in the Medline, Embase, Cochrane Library of systematic reviews and CENTRAL databases.

RESULTS

236 articles on exercise and 181 articles on weight were included. Exercise interventions resulted in improvements in outcomes such as pain and function across all the RMDs, although the size of the effect varied by RMD and intervention. Disease activity was not influenced by exercise, other than in axSpA. Increased body weight was associated with worse outcomes for the majority of RMDs and outcomes assessed. In general, study quality was moderate for the literature on exercise and body weight in RMDs, although there was large heterogeneity between studies.

CONCLUSION

The current literature supports recommending exercise and the maintenance of a healthy body weight for people with RMDs.

A systematic review of clinical practice guidelines for persons with osteoarthritis. A "Best Evidence for Rehabilitation" (be4rehab) paper to develop the WHO's Package of Interventions for Rehabilitation: A systematic review of Clinical Practice Guidelines for persons with osteoarthritis for the identification of best evidence for rehabilitation

AIM

Identifying existing interventions for rehabilitation and related evidence presents a crucial step in developing the World Health Organization's (WHO) Package of Interventions for Rehabilitation. This paper reports the results of a systematic search that aimed to identify clinical practice guidelines (CPGs) relevant to the rehabilitation of people with osteoarthritis and presents the CPG recommendations and the current state of evidence available for the interventions in the CPGs.

METHODS

This paper is part of the "Best Evidence for Rehabilitation" (be4rehab) series, developed according to the methodology presented in the WHO's Package of Interventions for Rehabilitation introductory paper by Rauch et al, published in 2019. It is a systematic review of the existing CPGs on osteoarthritis published between 2009 and 2019. Identified CPGs were screened taking into consideration conflict of interest, the provision of information regarding the strength of recommendation(s), and quality to be selected. Quality of CPGs was assessed using the AGREE II tool.

RESULTS

After title and abstract screening, 51 CPGs were identified. Considering the inclusion/exclusion criteria, 26 CPGs were selected. After checking for quality, comprehensiveness, multi-professionality, and publication date, five CPGs were finally included in the review. The strong recommendations for people with knee and hip osteoarthritis consistently included in all the selected CPGs, sometimes called "core treatments", were patient education, exercise training, and weight reduction if overweight or obese. Generally, recommendations overlap in the CPGs.

CONCLUSION

The systematic search revealed high-quality CPGs on osteoarthritis for the identification of "Best Evidence for Rehabilitation (be4rehab)" regarding interventions for rehabilitation of people with osteoarthritis.

Effectiveness and safety of Tai Chi for chronic pain of knee osteoarthritis: A protocol for systematic review and meta-analysis

BACKGROUND

Chronic pain (CP) has been a major area of interest in the field of knee osteoarthritis (KOA), further aggravating the dysthymia, stiffness, and dysfunction of KOA patients. As an important part of complementary and alternative medicine, Tai Chi has a positive effect on KOA patients. The systematic review is to evaluate the effectiveness and safety of Tai Chi for KOA patients with CP.

METHODS

A systematic search will be performed in the following electronic databases for randomized controlled trials to evaluate the effectiveness and safety of Tai Chi in treating chronic pain of knee osteoarthritis: the Cochrane Library, PubMed, EMBASE, OVID-MEDLINE, and four Chinese databases (Wan Fang, CNKI, CBMdisc and VIP). Each database will be searched from inception to Dec. 2021. The process will include study selection, data extraction, risk of bias assessment and meta-analysis.

RESULTS

This proposed study will evaluate the effectiveness and safety of Tai Chi for KOA patients with CP. Improvement in pain and adverse effects of KOA will be included in our measure.

CONCLUSIONS

This proposed systematic review and meta-analysis will evaluate the existing evidence on the effectiveness and safety of Tai Chi for KOA patients with CP.

DISSEMINATION AND ETHICS

The results of this review will be disseminated through peer-reviewed publication. This review does not require ethical approval because all of the data used in this systematic review and meta-analysis have already been published. Furthermore, all of these data will be analyzed anonymously during the review process.

Quality assessment of conventional and traditional oriental medicine clinical practice guidelines for knee osteoarthritis using AGREE II instrument

INTRODUCTION

Knee osteoarthritis is a degenerative disease and its prevalence tends to increase. Clinical practice guidelines (CPGs) are evidence-based recommendations for treatment that help policymakers, practitioners, and patients make more appropriate and efficient decisions during the course of management. This study aimed to evaluate the quality of knee osteoarthritis CPGs using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument.

METHOD

The retrieval engines and websites were utilized from January 2010 to December 2020. The search words were "Clinical practice guideline" OR "Critical practice guideline" OR "guideline∗" AND "Osteoarthritis." The quality of the CPGs was independently examined by four appraisers using the AGREE II instrument. Consequently, the selected CPGs were graded as Classes A, B, and C according to the level of recommendation.

RESULT

In this study, 13 CPGs for knee osteoarthritis were selected and evaluated qualitatively using the AGREE II instrument. The overall quality percentage score was as follows: clarity of presentation, 72.6%, scope and purpose, 62.6%, rigor of development, 54.2%, stakeholder investment, 50.5%, editorial independence, 46.5%, applicability, 22.5%.

CONCLUSION

Auxiliary materials for the treatment process of knee OA should be supplemented in future revised versions for quality improvement of knee OA CPGs. Also, more evidence should be accumulated to support the recommendation of traditional oriental medical treatments in the clinical field. From the perspective of integrative medicine, along with conventional pharmacological treatment, exercise, weight loss, and acupuncture can be combined together in clinical situations.

The basis of information to guide clinical decision-making in knee osteoarthritis management: A survey with Brazilian physical therapists

RATIONALE, AIMS AND OBJECTIVES

Several health information sources are available to assist physical therapists in the clinical decision-making process, with a notable increase in the importance of using evidence-based practice (EBP). The aim of this study is to investigate the health information sources most used by Brazilian physical therapists to guide their clinical decision making for knee osteoarthritis (OA) management, use of Physiotherapy Evidence Database (PEDro), knowledge about the existence of clinical practice guidelines (CPGs), and associated factors.

METHODS

A cross-sectional study using an electronic survey was conducted. Physical therapists registered in a Regional Physical Therapy Council in Brazil were invited to participate. Sociodemographic data, professional training, health information sources, frequency of use of PEDro, and knowledge about CPGs were collected. Descriptive analysis of the data was performed, and the chi square test and multinomial and binary logistic regression were used to verify association between the variables.

RESULTS

The survey was completed by 370 professionals. The three health information sources most used by Brazilian physical therapists were clinical experience, courses, and books. Among these professionals, only 12.1% use PEDro frequently, and 60.5% know that CPGs for knee OA management exist. Level of education was associated with PEDro use and knowledge about the existence of CPGs (P < .05).

CONCLUSIONS

The study results indicated a significant deficiency in engagement with research evidence by Brazilian physical therapists to guide their clinical decision making for knee OA. Further investigations on educational needs and the development of new strategies to narrow the gap between research evidence and clinical practice should be performed.

Therapeutic ultrasound for knee osteoarthritis: A systematic review and meta-analysis with grade quality assessment

BACKGROUND

Therapeutic ultrasound (US) is a widely used intervention in physical therapy to manage pain and to aid in the healing of soft tissue.

OBJECTIVE

This systematic review aimed to determine the effects of therapeutic US on knee osteoarthritis (KOA) symptoms.

METHODS

PubMed, MEDLINE, EMBASE, Google Scholar, and the Cochrane databases were searched from inception to April 2019. Randomized controlled trials (RCTs) involving adults with symptomatic KOA that compared therapeutic US with a sham or other control were included. The methodological quality of the trials was assessed at the study level using the Cochrane Risk of Bias tool. The quality of evidence at the outcome level- and overall- was assessed using GRADE methodology. Meta-analyses were conducted using random effects models, and heterogeneity was assessed using the I² statistic.

RESULTS

Four studies (N = 234 participants) were eligible for inclusion in our primary analyses assessing therapeutic US versus sham. The methodological quality of the included RCTs ranged from moderate to very low. Treatment with therapeutic US resulted in small, statistically significant benefits for pain (approximate 9.6% improvement on a 0-100 visual analog scale [95% confidence interval: 2, 17.4%]) and self-reported measures of function (approximate 12.8% improvement on a 0-100 visual analog scale [0.4, 25.2%]). The overall quality of the evidence was very low. No adverse events were reported in any of the included study.

CONCLUSIONS

The use of therapeutic US may provide additional benefits to physical therapy regimens in terms of symptom relief in individuals with KOA. However, it is not possible to make any meaningful recommendations for clinical practice due to the small number of applicable RCTs and the low methodological quality of the RCTs deemed eligible for this study.

Effects of variable frequencies of kinesthesia, balance and agility exercise program in adults with knee osteoarthritis: study protocol for a randomized controlled trial

Background

Knee osteoarthritis (OA) is a common painful and disabling condition that affects older individuals. Proprioceptive training programs in the form of kinesthesia, balance and agility (KBA) exercises have been reported to be beneficial for individuals with knee OA. However, the most optimal training dosage of KBA exercises is still unclear. The aim of this study is to determine the effects of different frequencies of KBA training (i.e., twice-weekly or thrice-weekly) in adults with knee OA.

Methods

A single (assessor) blind, three-arm parallel, multi-center randomized controlled trial will be conducted. One hundred twenty adults with knee OA will be recruited from four tertiary hospitals in Northwestern Nigeria and randomly assigned into one of three intervention groups; twice-weekly KBA (n = 40), thrice-weekly KBA (n = 40), and conventional physiotherapy (n = 40) in the ratio of 1:1:1. Participants in the conventional physiotherapy group will receive two sessions of brief patient education, and sixteen sessions of ultrasound therapy, and stretching and strengthening exercises for 8 weeks. Participants in the two different KBA groups will receive KBA training according to the designed sessions for 8 weeks in addition to the conventional physiotherapy program. All groups will be assessed pre-intervention, immediately post-intervention and at 3 months, 4 months, and 6 months post-randomization. The primary outcome will be physical function (Ibadan Knee and Hip Osteoarthritis Outcome Measure) whereas the secondary outcomes will be pain intensity (Visual Analogue Scale for pain), knee stability (Knee Outcome Survey-Activities of Daily Living Scale), proprioception (electronic goniometer), and quality of life (Osteoarthritis Knee and Hip Quality of Life Questionnaire).

Discussion

The findings of this study may provide evidence on the effectiveness of KBA exercise training and the ideal number of sessions needed to achieve the highest effectiveness in adults with knee OA.

Arthroscopy Association of Canada Position Statement on Exercise for Knee Osteoarthritis: A Systematic Review of Guidelines

BACKGROUND

Exercise is widely regarded to improve pain and function in patients with knee osteoarthritis (OA) through building supportive muscle mass, facilitating weight loss, and through the other beneficial effects associated with it.

PURPOSE

To explore literature that presents clinical guidelines for the use of exercise in the treatment of knee OA to inform an evidence-based position statement for the Arthroscopy Association of Canada.

STUDY DESIGN

Position statement.

METHODS

PubMed, MEDLINE, Embase, and Cochrane databases were searched for guidelines commenting on the role of exercise for knee OA. The search was limited to guidelines published in the last 10 years. Articles were screened for relevance, focusing on recently published research with clinical guidelines. Inclusion criteria involved all articles providing clinical guidelines for exercise and knee OA.

RESULTS

Eight guidelines were identified. All eight recommended exercise as an important component of treatment for knee OA, with 6/8 strongly recommending it.

CONCLUSION

Exercise is an effective and important component of the non-pharmacological management of knee OA. The Arthroscopy Association of Canada strongly recommends the use of exercise in the management of knee OA.

Non-Surgical Treatment of Knee Osteoarthritis: Multidisciplinary Italian Consensus on Best Practice

The aim of this document is to provide a set of indications on the national best practice management of knee osteoarthritis based on an analysis of the existing literature and the contribution of experts in the field. During the first phase of the project, in agreement with the multidisciplinary panel of experts, the main guidelines on the topic were selected. Each guideline was assessed through the AGREEII system to identify their strong/weak points and a summary of the recommendations contained in the various documents was drawn up. The panel drew up a list of therapeutic options to be included in the document and some of these topics were selected for in-depth analysis and review. The search strategy for the required literature reviews was constructed using the PICOS approach. The results obtained from the literature reviews, the in-depth analyses conducted by the members of the scientific societies involved and the analysis of the existing guidelines enabled an initial draft of the consensus document to be elaborated. This document was examined at the consensus conference held on 28 May 2019, in the presence of a multidisciplinary group consisting of members of the various scientific societies involved. Single recommendations were discussed in work groups with a view to combining the indications given by the literature examined with the experience of the specialists involved. The recommendations discussed were then put to the vote in a plenary assembly. The final document contains 26 practice recommendations which leading specialists involved in the management of knee OA in Italy agree upon.

The effects of an 8-week knitting program on osteoarthritis symptoms in elderly women: A pilot randomized controlled trial

BACKGROUND

Exercise therapy is effective in reducing symptoms and disability associated with hand osteoarthritis (HOA) but often has low adherence. An intervention consisting in a meaningful occupation, such as knitting, may improve adherence to treatment. This pilot randomized controlled trial (RCT) studied the adherence and clinical effectiveness of a knitting program in older females suffering from HOA to evaluate the acceptability of this intervention and assess the feasibility of a larger-scale RCT.

METHODS

Single-blind, two-arm pilot RCT with a parallel group design with 37 participants (18 control, 19 intervention). Control participants were given an educational pamphlet and assigned to a waiting list. The knitting program (8-week duration) had two components: bi-weekly 20-min group knitting sessions and daily 20-min home knitting session on the 5 remaining weekdays. Measures included knitting adherence (implementation outcomes) as well as stiffness, pain, functional status, hand physical activity level, patient's global impression of change, health-related quality of life, self-efficacy, and grip strength (clinical outcomes measured throughout the 8-week program and 4 weeks after the intervention).

RESULTS

Our protocol is feasible and the intervention was acceptable and enjoyable for participants, who showed high adherence. No difference was observed between the two groups for any of the clinical outcome measures (all p > .05).

CONCLUSION

Knitting is a safe and accessible activity for older women with HOA. However, our 8-week knitting program did not result in improvements in any of our outcome measures. Knitting for a longer period and/or with higher frequency may yield better outcomes.

The effects on pain, physical function, and quality of life of quadriceps strengthening exercises combined with Baduanjin qigong in older adults with knee osteoarthritis: a quasi-experimental study

BACKGROUND

Exercise is recommended as a principal treatment for individuals with knee osteoarthritis (KOA). However, the best choice for an optimal exercise program able to promote long-term compliance in KOA patients is not clear. This study aims to compare the effect of combined exercise (CE: quadriceps strengthening exercises (QSE) and Baduanjin qigong training (BDJ)) versus QSE alone and BDJ alone on older adults with KOA.

METHODS

A three-arm, quasi-experimental trial with repeated measurements was used. As a cluster randomized trial, participants from three community centers were assigned respectively to QSE group, BDJ group and CE group. We assessed pain intensity, physical function, self-efficacy, and health-related quality-of-life (HRQoL) using standardized instruments at baseline, 3 months and 6 months follow-up.

RESULTS

One hundred and twenty-eight participants with KOA aged over 60 completed the study. Over the 6 months, there were significant group interaction effects on pain intensity (F = 28.888, P < 0.001), physical function (F = 26.646, P < 0.001), and self-efficacy (F = 22.359, P < 0.001), and, based on a short form-12 item health survey questionnaire (SF-12), physical component summary (F = 7.470, P < 0.001), and mental component summary (F = 10.207, P < 0.001). Overall, the CE group exhibited significantly greater improvement in all outcomes when compared to the QSE group and the BDJ group.

CONCLUSIONS

CE treatment is more effective than QSE and BDJ in pain relief, increasing physical function, improving self-efficacy, and raising quality-of-life in community-dwelling KOA older adults. Moreover, it promotes long-term compliance in KOA community patients.

Knee osteoarthritis: key treatments and implications for physical therapy

BACKGROUND

Knee osteoarthritis (OA) is a chronic progressive disease that imparts a substantial socioeconomic burden to society and healthcare systems. The prevalence of knee OA has dramatically risen in recent decades due to consistent increases in life expectancy and obesity worldwide. Patient education, physical exercise, and weight loss (for overweight or obese individuals) constitute the first-line knee OA treatment approach. However, less than 40% of patients with knee OA receive this kind of intervention. There is an unmet need for healthcare professionals treating individuals with knee OA to understand the current recommended treatment strategies to provide effective rehabilitation.

OBJECTIVE

To guide physical therapists in their clinical decision making by summarizing the safest and most efficacious treatment options currently available, and by delineating the most traditional outcome measures used in clinical research for knee OA.

CONCLUSION

There is a need for healthcare providers to abandon low-quality and ineffective treatments and educate themselves and their patients about the current best evidence-based practices for knee OA.

Quality and content analysis of clinical practice guidelines which include nonpharmacological interventions for knee osteoarthritis

RATIONALE, AIMS, AND OBJECTIVES

Clinical practice guidelines (CPGs) for knee osteoarthritis (OA) guide the provision of high-quality healthcare for people with knee OA, which may improve outcomes. Our aim was to evaluate the quality of and content within recently published CPGs for people with knee OA.

METHODS

CPGs (2014-2019) that described recommendations for nonpharmacological interventions for knee OA were included in the analysis. Two pairs of evaluators used the Appraisal of Guidelines Research and Evaluation II instrument (AGREE II) to assess the quality of guideline development. CPG content was reviewed and summarized for comparison.

RESULTS

Ten CPGs were identified for inclusion in the quality and content analysis (seven newly developed and three recently updated). Overall CPG scores ranged between 42% and 100%. Six CPGs were found to be high-quality. Exercise was the only intervention recommended by all CPGs that we appraised. Weight-management and education were the next most frequently recommended interventions. Inter-rater reliability scores were high in domain 1: scope and purpose, (P-value = .001, intraclass correlation coefficient [ICC] = 0.90, 95% confidence interval [CI] = 0.62-0.98), domain 3: rigor of development (P-value = .000, ICC = 0.95, 95% CI = 0.80-0.99) and domain 5: applicability (P-value = .001, ICC = 0.91, 95% CI = 0.64-0.98).

CONCLUSION

Several CPGs have been developed or recently updated since 2014. Over half of the ten CPGs we appraised were deemed to be high-quality. Exercise, education, and weight-management advice are interventions that were most commonly recommended by CPGs.

Determining the feasibility of a trial to evaluate the effectiveness of phototherapy versus placebo at reducing pain during physical activity for people with knee osteoarthritis: a pilot randomized controlled trial

BACKGROUND

Although practice guidelines recommend physical activity and exercise for the management of knee osteoarthritis, pain is a common barrier to participation. Phototherapy has been shown to reduce pain intensity for people with knee osteoarthritis, but it is unclear if it reduces pain during physical activity or contributes to improved rehabilitation outcomes.

OBJECTIVE

The aim of this study is to assess the feasibility of performing a fully powered randomized controlled trial (RCT) comparing an active phototherapy intervention versus placebo on pain during physical activity for people with knee osteoarthritis.

METHODS

A pilot RCT was conducted to test the feasibility of a trial comparing 8-sessions (4 weeks) of active phototherapy versus placebo. People were able to participate if they (1) were an English speaking adult (> 18 years of age), (2) had received a diagnosis of knee osteoarthritis from a physician, and (3) self-reported experiencing pain and disability related to their knee osteoarthritis for > 3 months. Primary outcomes were the feasibility of participant recruitment, retention, assessment procedures, and maintaining high treatment fidelity. Secondary outcomes piloted for a full trial included pain during physical activity (primary outcome of full trial); self-reported pain severity, physical function, stiffness, adherence to prescribed exercise, global rating of change, patient satisfaction, and adverse events; 6-min walk test; and pressure pain threshold.

RESULTS

Twenty participants (4 men; 16 women) with knee osteoarthritis and a mean age of 63.95 (SD: 9.27) years were recruited over a 3-week period (6.7 participants per week). Fifteen out of 20 (75%) of participants completed the primary outcome assessment at 4 weeks and 19/20 (95%) of participants were retained and completed the final 16-week assessment. Overall, 89% of all assessment items were completed by participants across all time-points. Fifteen out of 20 participants (75%) completed all 8 treatment sessions. Treatment fidelity was 100% for all completed treatment sessions. No adverse events were reported by participants in either group.

CONCLUSIONS

Results suggest that the trial methodology and intervention are feasible for implementation in a fully powered randomized controlled trial to determine the effectiveness of phototherapy at reducing pain during physical activity for people with knee osteoarthritis.

Stationary cycling exercise for knee osteoarthritis: A systematic review and meta-analysis

OBJECTIVE

To evaluate effects of stationary cycling exercise on pain, function and stiffness in individuals with knee osteoarthritis.

DATA SOURCES

Systematic search conducted in seven databases (PubMed, Embase, Cochrane Library, Web of Science, EBSCO, PEDro, and CNKI) from inception to September 2020.

REVIEW METHODS

Included studies were randomized-controlled trials involving stationary cycling exercise conducted on individuals with knee osteoarthritis. End-trial weighted mean difference (WMD) and 95% confidence interval (CI) were analyzed, and random-effects models were used. Methodological quality and risk bias were assessed by using the Physiotherapy Evidence Database scale and Cochrane Collaboration tool, respectively.

RESULTS

Eleven studies with 724 participants were found, of which the final meta-analysis was performed with eight. Compared to a control (no exercise), stationary cycling exercise resulted in reduced pain (WMD 12.86, 95% CI 6.90-18.81) and improved sport performance (WMD 8.06, 95% CI 0.92-15.20); although most of the meta-analysis results were statistically significant, improvements in stiffness (WMD 11.47, 95% CI 4.69-18.25), function (WMD 8.28, 95% CI 2.44-14.11), symptoms (WMD 4.15, 95% CI -1.87 to 10.18), daily living (WMD 6.43, 95% CI 3.19 to 9.66) and quality of life (WMD 0.99, 95% CI -4.27 to 6.25) for individuals with knee osteoarthritis were not greater than the minimal clinically important difference values for each of these outcome measures.

CONCLUSIONS

Stationary cycling exercise relieves pain and improves sport function in individuals with knee osteoarthritis, but may not be as clinically effective for improving stiffness, daily activity, and quality of life.

Nonpharmacological and nonsurgical approaches in OA

Osteoarthritis (OA) is a chronic, disabling, and common disease. Nonpharmacological and nonsurgical treatments are seen as the core treatments for OA. This paper presents an overview of the recommendations from international guidelines on nonpharmacological and nonsurgical interventions. Education, advice, or information about the etiology, progression, prognosis, and treatment options of OA are recommended to be an ongoing and integral part of care. Weight loss (if overweight) is an important core treatment in knee and hip OA. Exercise is a key core treatment in knee, hip, and hand OA and should be considered regardless of age, structural disease severity, functional status, pain levels, or the presence of comorbidities. Walking aids/devices are recommended for both hip and knee OA, while orthoses are recommended for patients with carpometacarpal (CMC) joint OA. Trained healthcare providers with the skills to provide the core treatments are essential. In addition, there should be a proactive management from the first consultation for OA symptoms. Tools for such proactive management and for better uptake of the core interventions are discussed.

Research Trends of Acupuncture Therapy on Knee Osteoarthritis from 2010 to 2019: A Bibliometric Analysis

Background

Acupuncture has been widely applied to relieve knee osteoarthritis (KOA) in many countries. However, the bibliometric analysis of the global use of acupuncture on KOA is largely unknown. Therefore, this study aimed to explore the current status and trends of the global use of acupuncture on KOA in recent 10 years by using CiteSpace (5.6.R3).

Methods

Publications regarding acupuncture therapy for treating KOA between 2010 and 2019 were extracted from the Web of Science database. CiteSpace was used to analyze the number of publications, countries, institutions, journals, authors, cited references and keywords by using standard bibliometric indicators.

Results

A total of 343 publications were retrieved from 2010 to 2019. The total number of publications continually increased over the past four years, and the most active journals, countries, institutions and authors in the field of acupuncture therapy on patients with KOA were identified. The Evid Based Complement Alternat Med (28) was the most prolific journal, and the Ann Intern Med (202) was the most cited journal. The most productive country and institution in this field was China (115) and University of York (18), respectively. Hugh Macpherson (18) was the most prolific author and Witt C ranked the first in the cited authors. In the ranking of frequency in cited reference, the first article was published by Scharf HP (54). The keyword of ‘randomized controlled trial’ ranked first for research developments with the highest citation burst (3.9486). Besides, there were three main frontiers in keywords for KOA research, including ‘research method, ‘age’ and ‘measure of intervention’.

Conclusion

The findings from this bibliometric study provide current status and trends in clinical research of acupuncture therapy on patients with KOA over the past ten years, which may help researchers identify hot topics and explore new directions for future research in this field.

Short-Term Effect of a New Oral Sodium Hyaluronate Formulation on Knee Osteoarthritis: A Double-Blind, Randomized, Placebo-Controlled Clinical Trial

Objective: the aim of this pilot study was to test the short-term effect of oral supplementation with a sodium hyaluronate with a large spectrum of molecular weights (FS-HA^®) on the symptoms and functionality of knee osteoarthritis (OA). Methods: 60 subjects affected by clinical and/or radiological diagnosis of symptomatic knee OA were consecutively enrolled in a randomized, double blind, placebo-controlled, clinical trial. At randomization visit, at day 28 (visit 2), and day 56 (visit 3), the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC), the Lequesne Functional Index (LFI) and the Visual Analogue Scale (VAS) for pain (VAS-p) were administered to the enrolled patients. Then, patients were asked how many times they used rescue medications (non-steroidal antinflammatory drugs–NSAIDs and/or anti-pain drugs) during the previous 4 weeks. Finally, the range of knee joint motion (ROM) was also instrumentally measured. Results: In FS-HA^® treated subjects, VAS-p, pain and total WOMAC score, LFI and ROM significantly improved compared to the baseline values (p < 0.05). At 60 days, the VAS-p and the pain WOMAC score were significantly lower after FS-HA^® treatment when compared with placebo as well (p < 0.05). The FS-HA^® treated subjects significantly reduced the weekly use of NSAIDs and/or antipain drugs when compared to the placebo-treated ones (p < 0.05). Conclusion: the oral supplementation with a FS-HA^® characterized by a large spectrum of molecular weight was associated with a short-term improvement in symptomatology and functionality of osteoarthritis-affected knees, and associated with a reduction in the use of NSAIDS and anti-pain drugs.

The Tai Chi training for middle-aged and elderly patients with knee osteoarthritis: A protocol for systematic review and meta analysis

BACKGROUND

Knee osteoarthritis (KOA) is a disabling joint disease with an increasingly prevalence among the older individuals. Tai Chi, one of the ancient meditative movements, has been recognized to have clinical benefits for KOA. We aim to evaluate the efficacy and safety of Tai Chi for patients with KOA through this systematic review.

METHODS

Five English databases (Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, AMED, and CINAHL), 4 Chinese databases (CBM, CNKI, CQVIP, and Wanfang), and 5 clinical trial registration databases (ClinicalTrials.gov, ANZCTR, EU-CTR, ChiCTR, and ICTRP) will be searched from establishment of the database until November 31, 2019. Grey literature will be searched in SIGLE, Grey Net, Microsoft Academic, Google Scholar, Open Aire, World Wide Science.org, and WorldCat. There will be no restrictions on language. The randomized controlled trials of Tai Chi training for patients with KOA will be included. The primary outcome will be assessed according to the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Meta-analysis will be conducted with the use of RevMan 5.3. The specific process will refer to the Cochrane Handbook 5.1 for Systematic Review.

RESULTS

High-quality synthesis of current evidence on the efficacy and safety of Tai Chi training for KOA will be provided in this study.

CONCLUSION

This systematic review aims to present evidence for whether Tai Chi training is an effective intervention which can improve both physical condition and life quality in patients suffering KOA.

Microcurrent therapy in the treatment of knee osteoarthritis: could it be more than a placebo effect? A randomized controlled trial

BACKGROUND

Microcurrent therapy (MCT) is a novel electrotherapy modality with very low current-levels that may reduce pain especially in joints and muscles.

AIM

The aim of this study is to explore potential effects of MCT on pain in patients with knee osteoarthritis, to explore effects of different treatment parameters and to distinguish them from placebo-effects.

DESIGN

Randomized four arms controlled clinical trial.

SETTING

Outpatient tertiary medical care center.

POPULATION

Fifty-six patients with knee OA (Kellgren-Lawrence Score II or III, 14 male and 38 female, mean age: 71.7±7.3 years, pain intensity higher than Numeric Rating Scale [NRS] score 3 from 10).

METHODS

Patients were randomized into four groups: MCT with 100 µA (group A), MCT with 25 µA (group B), sham-treatment (group C) and a control-group without intervention. Treatment groups received 10 sessions of MCT for 30 minutes each over a period of 22 days. The primary outcome was daily pain intensity throughout the treatment period measured by a NRS from 0-10. Second outcome measurements were the Knee Osteoarthritis Outcome Score (KOOS), the SF-36 Questionnaire, the Six-Minute Walking Test and the Get-Up-and-Go Test.

RESULTS

Evening pain was reduced significantly in the verum-groups compared to sham group (Group A vs. Group C: P<0.001, Group B vs. Group C: P=0.006) and to no intervention (Group A vs. Group D: P<0.001, Group B vs. Group D: P=0.002). The difference between sham-therapy and no therapy was not significant. In the pre-post analysis of the KOOS group A improved significantly in the subscale Symptoms. Group A and B and D improved in the Activities of Daily Living subscale.

CONCLUSIONS

The results of this RCT suggest that MCT has beneficial effects on pain in patients with knee osteoarthritis that are not explained by a placebo effect. Due to the explorative, pilot character of the study, further confirmation is needed before clear recommendations can be given.

CLINICAL REHABILITATION IMPACT

More high-quality RCTs with transparent parameters should be investigated to elucidate potential effects of MCT in the field of physical medicine and rehabilitation. At the present time MCT is a treatment option that could be helpful, in particular for patients who are afraid of unpleasant sensations from electrotherapy with stronger currents.

Relative Efficacy of Different Exercises for Pain, Function, Performance and Quality of Life in Knee and Hip Osteoarthritis: Systematic Review and Network Meta-Analysis

Background

Guidelines recommend exercise as a core treatment for osteoarthritis (OA). However, it is unclear which type of exercise is most effective, leading to inconsistency between different recommendations.

Objectives

The aim of this systematic review and network meta-analysis was to investigate the relative efficacy of different exercises (aerobic, mind–body, strengthening, flexibility/skill, or mixed) for improving pain, function, performance and quality of life (QoL) for knee and hip OA at, or nearest to, 8 weeks.

Methods

We searched nine electronic databases up until December 2017 for randomised controlled trials that compared exercise with usual care or with another exercise type. Bayesian network meta-analysis was used to estimate the relative effect size (ES) and corresponding 95% credibility interval (CrI) (PROSPERO registration: CRD42016033865).

Findings

We identified and analysed 103 trials (9134 participants). Aerobic exercise was most beneficial for pain (ES 1.11; 95% CrI 0.69, 1.54) and performance (1.05; 0.63, 1.48). Mind–body exercise, which had pain benefit equivalent to that of aerobic exercise (1.11; 0.63, 1.59), was the best for function (0.81; 0.27, 1.36). Strengthening and flexibility/skill exercises improved multiple outcomes at a moderate level. Mixed exercise was the least effective for all outcomes and had significantly less pain relief than aerobic and mind–body exercises. The trend was significant for pain (p = 0.01), but not for function (p = 0.07), performance (p = 0.06) or QoL (p = 0.65).

Conclusion

The effect of exercise varies according to the type of exercise and target outcome. Aerobic or mind–body exercise may be the best for pain and function improvements. Strengthening and flexibility/skill exercises may be used for multiple outcomes. Mixed exercise is the least effective and the reason for this merits further investigation.
