Implementing a structured model for osteoarthritis care in primary healthcare: A stepped-wedge cluster-randomised trial

BACKGROUND

To improve quality of care for patients with hip and knee osteoarthritis (OA), a structured model for integrated OA care was developed based on international recommendations. The objective of this study was to assess the effectiveness of this model in primary care.

METHODS AND FINDINGS

We conducted a cluster-randomised controlled trial with stepped-wedge cohort design in 6 Norwegian municipalities (clusters) between January 2015 and October 2017. The randomised order was concealed to the clusters until the time of crossover from the control to the intervention phase. The intervention was implementation of the SAMBA model, facilitated by interactive workshops for general practitioners and physiotherapists with an update on OA treatment recommendations. Patients in the intervention group attended a physiotherapist-led OA education and individually tailored exercise programme for 8-12 weeks. The primary outcome was patient-reported quality of care (OsteoArthritis Quality Indicator questionnaire; 0-100, 100 = optimal quality) at 6 months. Secondary outcomes included patient-reported referrals to physiotherapy, magnetic resonance imaging (MRI), and orthopaedic surgeon consultation; patients' satisfaction with care; physical activity level; and proportion of patients who were overweight or obese (body mass index ≥ 25 kg/m2). In all, 40 of 80 general practitioners (mean age [SD] 50 [12] years, 42% females) and 37 of 64 physiotherapists (mean age [SD] 42 [8] years, 65% females) participated. They identified 531 patients, of which 393 patients (mean age [SD] 64 [10] years, 71% females) with symptomatic hip or knee OA were included. Among these, 109 patients were recruited during the control periods (control group), and 284 patients were recruited during interventions periods (intervention group). The patients in the intervention group reported significantly higher quality of care (score of 60 versus 41, mean difference 18.9; 95% CI 12.7, 25.1; p < 0.001) and higher satisfaction with OA care (odds ratio [OR] 12.1; 95% CI 6.44, 22.72; p < 0.001) compared to patients in the control group. The increase in quality of care was close to, but below, the pre-specified minimal important change. In the intervention group, a higher proportion was referred to physiotherapy (OR 2.5; 95% CI 1.08, 5.73; p = 0.03), a higher proportion fulfilled physical activity recommendations (OR 9.3; 95% CI 2.87, 30.37; p < 0.001), and a lower proportion was referred to an orthopaedic surgeon (OR 0.3; 95% CI 0.08, 0.80; p = 0.02), as compared to the control group. There were no significant group differences regarding referral to MRI (OR 0.6; 95% CI 0.13, 2.38; p = 0.42) and proportion of patients who were overweight or obese (OR 1.3; 95% CI 0.70, 2.51; p = 0.34). Study limitations include the imbalance in patient group size, which may have been due to an increased attention to OA patients among the health professionals during the intervention phase, and a potential recruitment bias as the patient participants were identified by their health professionals.

CONCLUSIONS

In this study, a structured model in primary care resulted in higher quality of OA care as compared to usual care. Future studies should explore ways to implement the structured model for integrated OA care on a larger scale.

Short-term cryotherapy did not substantially reduce pain and had unclear effects on physical function and quality of life in people with knee osteoarthritis: a randomised trial

OBJECTIVE

Does short-term cryotherapy improve pain, function and quality of life in people with knee osteoarthritis (OA)?

DESIGN

Randomised controlled trial with concealed allocation, blinded assessment of some outcomes, and intention-to-treat analysis.

PARTICIPANTS

People living in the community with knee OA.

INTERVENTIONS

The experimental group received cryotherapy, delivered as packs of crushed ice applied to the knee with mild compression. The control group received the same regimen but with sham packs filled with sand. The interventions were applied once a day for 4 consecutive days.

OUTCOME MEASURES

Participants were assessed at baseline and on the day after the 4-day intervention period. The primary outcome was pain intensity according to a visual analogue scale. Secondary outcomes were baseline to post-intervention changes according to the Western Ontario and McMaster Universities Osteoarthritis, Knee injury and Osteoarthritis Outcome; Timed Up and Go test; and 30-Second Chair to Stand test.

RESULTS

Sixty participants were randomised into the experimental group (n = 30) or the control group (n = 30). Twenty-nine participants from each group completed the trial. The mean between-group difference in change in pain severity was -0.8 cm (95% CI -1.6 to 0.1), where negative values favour the experimental group. This result did not reach the nominated smallest worthwhile effect of 1.75 cm. The secondary outcomes had less-precise estimates, with confidence intervals that spanned worthwhile, trivial and mildly harmful effects.

CONCLUSION

Short-term cryotherapy was not superior to a sham intervention in terms of relieving pain or improving function and quality of life in people with knee OA. Although cryotherapy is considered to be a widely used resource in clinical practice, this study does not suggest that it has an important short-term effect, when compared with a sham control, as a non-pharmacological treatment for people with knee osteoarthritis.

Perceived barriers to and facilitators of physical activity in people with knee osteoarthritis: Development of the Evaluation of the Perception of Physical Activity questionnaire

BACKGROUND

The physical activity (PA) level of individuals with knee osteoarthritis is lower than in the general population. International recommendations recommend a non-pharmacological intervention including a self-management education program, weight loss and an adapted exercise program. However, we have no scale assessing the perceived barriers to and facilitators of PA in this population.

OBJECTIVE

We constructed and validated a self-administered questionnaire assessing perceived barriers to and facilitators of regular practice of PA in people with knee osteoarthritis.

METHODS

Semi-structured interviews identified 24 barriers and facilitators. We developed a 24-item questionnaire, Evaluation of the Perception of Physical Activity (EPPA) that was completed by 548 individuals with knee osteoarthritis, to assess acceptability, construct validity, internal consistency and convergent validity. Participants also completed the Knee Osteoarthritis Fears and Beliefs Questionnaire (KOFBeQ), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and International Physical Activity Questionnaire (IPAQ). Reliability and sensitivity to change were evaluated in a second group of 168 people with knee osteoarthritis at a 3-week spa therapy resort.

RESULTS

Factorial analysis identified 17 items grouped into 4 subscales (Barriers, Facilitators, Motivation and Beliefs). The internal consistency was good for Barriers, Facilitators and Motivation subscales (Cronbach α>0.70) and intermediate for the Beliefs subscale (Cronbach α=0.64). The EPPA subscale scores were significantly correlated with KOFBeQ and WOMAC scores but not associated with IPAQ physical activity level. Reliability was good for all subscales, with intraclass correlation coefficients>0.60. A sensitivity to change was found for only the Beliefs subscale, with a moderate effect size.

CONCLUSIONS

The EPPA questionnaire has good psychometric properties and can help guide the management of knee osteoarthritis. It can be used in research for evaluating the perception of physical activity.

The Better Management of Patients with Osteoarthritis Program: Outcomes after evidence-based education and exercise delivered nationwide in Sweden

We evaluated a structured education- and exercise-based self-management program for patients with knee or hip osteoarthritis (OA), using a registry-based study of data from 44,634 patients taken from the Swedish “Better Management of Patients with Osteoarthritis” registry. Outcome measures included a numeric rating scale (NRS), EuroQol five dimension scale (EQ-5D), Arthritis self-efficacy scale (ASES-pain and ASES-other symptoms), pain frequency, any use of OA medication, desire for surgery, fear–avoidance behavior, physical activity, and sick leave were reported at baseline, 3 and 12 month. Changes in scale variables were analyzed using general linear models for repeated measures and changes in binary variables by McNamara’s test. All analyses were stratified by joint. At the 3-month follow-up, patients with knee (n = 30686) and hip (n = 13948) OA reported significant improvements in the NRS-pain, the EQ-5D index, the ASES-other symptoms, and ASES-pain scores with standardized effect size (ES) ranges for patients with knee OA of 0.25–0.57 and hip OA of 0.15–0.39. Significantly fewer patients reported pain more than once weekly, took OA medication, desired surgery, showed fear–avoidance behavior, and were physically inactive. At the 12-month follow-up, patients with knee (n = 21647) and hip (n = 8898) OA reported significant improvements in NRS-pain, EQ-5D index, and a decrease in ASES-other symptoms and ASES-pain scores with an ES for patients with knee OA of –0.04 to 0.43 and hip OA of –0.18 to 0.22. Significantly fewer patients reported daily pain, desired surgery (for hip OA), reported fear–avoidance behavior, and reported sick leave. Following these interventions, patients with knee and hip OA experienced significant reductions in symptoms and decreased willingness to undergo surgery, while using less OA medication and taking less sick leave. The results indicate that offering this program as the first-line treatment for OA patients may reduce the burden of this disease.

Immediate effects of Mulligan's techniques on pain and functional mobility in individuals with knee osteoarthritis: A randomized control trial

BACKGROUND AND PURPOSE

Mulligan's mobilization with movement was shown to be effective when implemented in multimodal therapy for knee osteoarthritis. However, no study has evaluated the Mulligan's technique in isolation and compared the relative effectiveness with sham-controlled interventions. Hence, the present study examined the immediate effects of Mulligan's techniques with sham mobilization on the numerical pain rating scale (NPRS) and timed up and go (TUG) test in individuals with knee osteoarthritis.

METHODS

Thirty participants (mean age: 55.3 ± 8.3 years) with symptoms at the knee and radiographic diagnosis of knee osteoarthritis were randomized into sham (n = 15) and intervention (n = 15) groups. The intervention (I) group received Mulligan's mobilization glides that resulted in relative pain relief for three sets of 10 repetitions. For the sham (S) group, the therapist's hand was placed over the joint surfaces mimicking the pain-relieving glides, without providing the gliding force. The outcome measures NPRS and TUG were recorded by a blinded assessor pre- and post-intervention.

RESULTS

Statistically significant differences were identified between the groups in post-intervention median (interquartile range) NPRS (I group: 4.00 [2.00-5.00]; S group: 6.00 [4.00-7.00]) and TUG scores (I group: 10.9 [9.43-10.45]; S group: 13.18 [10.38-16.00]) with the intervention group demonstrating better outcomes (p < .05). Within-group, the post-intervention scores of NPRS and TUG were significantly lower (p < .05) compared to the pre-intervention scores in the intervention group. In the sham group, a statistically significant pre-post change was noticed only in the NPRS scores but not in the TUG scores.

CONCLUSION

Mulligan's techniques were effective in improving pain and functional mobility in individuals with knee osteoarthritis. The underlying mechanisms for observed effects must be examined further, as participants reported pain relief following sham mobilization.

[Prescription frequency of physical therapy and analgesics before total hip and knee arthroplasy : An epidemiological analysis of routine health care data from Germany]

BACKGROUND

Osteoarthritis of the hip or knee joint is a widespread disease with a strong influence on the quality of life. At present, the extent of conservative treatment with physical therapies and analgesics before the use of a total joint arthroplasty (TJA) of the hip or knee is largely unclear in Germany.

OBJECTIVES

The aim was to analyze the prescription frequency according to regional and socio-demographic factors.

MATERIALS AND METHODS

Based on routine health care data from BARMER insurance, patients who received a TJA of the hip or knee from 2011 to 2013 were analyzed. Included were consistently insured patients with the main discharge diagnosis of osteoarthritis who did not receive any further TJA for eight quarters before and after replacement. The prescription frequency of physical therapies and analgesics, stratified according to age groups, gender, number of comorbidities and federal state was analyzed.

RESULTS

40,242 persons with hip TJA and 35,652 persons with knee TJA were included. In the year prior to surgery, 49.4% of patients (hip TJA: 49.9%; knee TJA: 48.9%) received at least one physical therapy and 81.0% were prescribed analgesics. Regionally, the prescription frequency of physical therapies for hip TJA varied between 35.7% (Bremen) and 70.6% (Saxony) and for knee TJA between 37.6% (Saarland) and 66.9% (Saxony).

CONCLUSION

The prescription frequency of physical therapy does not fully correspond to current treatment recommendations. The prescription of physical therapies in the year before the TEP shows regional differences, with fundamentally lower prescription frequencies in the former states of West Germany.

Efficacy of intra-articular hyaluronic acid injections in the rehabilitation programme of Knee Osteoarthritis

Abstract Knee osteoarthritis (KOA) is a disease of wear and tear, leading to disability and ultimate surgical treatment. KOA has multiple etiologies and is considered a disorder of physiological processes that is manifested by progressive lesions of articular cartilage caused by chondrolysis, synovial membrane inflammation and subchondral osteophytes production. Modalities that limit the progression of the KOA and rehabilitation are a constant interest for clinicians and medical researchers. Various physical therapies and pharmacological strategies are currently used for pain management, with no clear benefit in terms of inhibiting disease progression. In this context, the use of exogenous hyaluronic acid (HA) (that is a vital component of the synovial fluid and involved in lubricating all synovial joints) has been explored as viable alternative to alleviate knee pain and temporarily restore knee function. In the following, we will review the use of HA injections associated with the physiotherapeutic recovery plan in the treatment of KOA. The therapeutic effects of the HA is still a matter of debate in the field, with no consensus being reached so far and thus, difficult to evaluate. However, much research has to be done to understand the therapeutic efficacy of HA alone or in combination with physical therapies and the role that other factors may play in unraveling its beneficial effects on the KOA. Key words: knee, osteoarthritis, hyaluronic acid, physiotherapy, rehabilitation,

Development and evaluation of a tailored e-self-management intervention (dr. Bart app) for knee and/or hip osteoarthritis: study protocol

Background

This paper describes (the development of) an eHealth tool (dr. Bart app) to enhance self-management and to optimize non-surgical health care utilization in patients with knee and/or hip osteoarthritis (OA) and presents a study aiming 1) to study the effectiveness of the dr. Bart app on health care use 2) to explore differences in use, usability and the clinical outcomes of the dr. Bart app between the Netherlands and Germany.

Methods

The dr. Bart app is a fully automated eHealth application and is based on the Fogg model for behavioural change, augmented with reminders, rewards and self-monitoring to reinforce app engagement and health behaviour. The dr. Bart app propose goals to a healthier lifestyle based on machine learning techniques fed by data collected in a personal profile and choosing behaviour of the app user. Patients ≥50 years with self-reported knee and/or hip OA will be eligible to participate. Participants will be recruited in the community through advertisements in local newspapers and campaigns on social media. This protocol presents a study with three arms, aiming to include 161 patients in each arm. In the Netherlands, patients are randomly allocated to usual care or dr. Bart app and in Germany all patients receive the dr. Bart app. The primary outcome of the first research question is the number of self-reported consultations in secondary health care. The primary outcome of the second research question (comparison between the Netherlands and Germany) is self-management behaviour assessed by the patient activation measure (PAM-13) questionnaire. Secondary outcomes are costs, health-related quality of life, physical functioning and activity, pain, use and usability of the dr. Bart app. Data will be collected through three online questionnaires (at baseline and after 3 and 6 months after inclusion).

Discussion

This study will gain insight into the effectiveness of the dr. Bart app in the (conservative) treatment of patients with knee and/or hip OA and differences in the use and usability of the dr. Bart app between the Netherlands and Germany.

The effectiveness of Kinesio Taping® for pain management in knee osteoarthritis: a randomized, double-blind, controlled clinical trial

Background:

Kinesio Taping® method is a nonpharmacological alternative for pain management in musculoskeletal disorders. However, the existing evidence is insufficient to assess its full effectiveness for pain management in knee osteoarthritis (KO). Our aim was to evaluate the effectiveness of the Kinesio Taping method in reducing knee pain for KO patients.

Methods:

In this randomized, double blind, controlled trial, we recruited 187 patients with grade I-III KO who were allocated to either the Kinesio Taping or control group. The study was carried out in outpatient facility. Either Kinesio Taping or nonspecific taping was applied on the affected knee area for 4 weeks. Pain evaluation was performed at baseline, after 1 month of taping and after 1 further month without taping. The data on usage of painkillers were collected; Numeric Pain Rating Scale; an algometer, and Knee injury and Osteoarthritis Outcome Scores (KOOS) pain subscale were used to assess pain. Tolerance and subjective opinions toward the effectiveness of taping were evaluated. The chosen level of significance was p < 0.05, ß ⩽ 0.2.

Results:

The majority (>70%) of both groups’ patients indicated that tapes reduced the knee pain. The reported use of painkillers decreased, in addition to self-reported increase in the KOOS subscale, thereby indicating pain alleviation. All self-reported improvement remained at the 1-month follow up (p < 0.05). Significantly higher and clinically meaningful reduction of pain intensity was found in the Kinesio Taping group after the treatment month, in comparison with the control group (p < 0.05). More pain reduction was reported in the daytime for participants in the Kinesio Taping group at the follow up (p = 0.022). No changes in algometry results were observed.

Conclusions:

Elastic taping can safely relieve knee pain and reduce the need for pharmacological management in KO. A specific Kinesio Taping technique is clinically more beneficial for knee-pain alleviation in comparison with nonspecific taping.

Comparison of the effects of 10.6-μm infrared laser and traditional moxibustion in the treatment of knee osteoarthritis

Based on two separate randomized controlled trials (RCTs) on traditional Chinese medicine (TCM) moxibustion and 10.6-μm infrared laser moxibustion in treating knee osteoarthritis (OA), we did an indirect and preliminary comparison of the effects of the 10.6-μm laser moxibustion with the traditional moxibustion for knee osteoarthritis. The objective was to see whether the laser moxibustion is non-inferior to the traditional moxibustion in alleviating symptoms of knee osteoarthritis such as pain, stiffness, and joint dysfunction as well as improving quality of life for the patients with knee osteoarthritis, and whether a further RCT directly comparing the laser and traditional moxibustion is necessary. Pooled data from two RCTs in patients with knee osteoarthritis, trial ISRCTN68475405 and trial ISRCTN26065334, were used. In the two RCTs, the eligibility criteria were almost identical, the treatment procedure (i.e., sessions, duration, and points) were similar, and the outcome measurements (i.e., WOMAC for symptoms and SF-36 for quality of life) were the same. The double robustness method was used for the WOMAC scale and the SF-36 endpoints to detect the difference between traditional and laser moxibustion. The analysis comprised 55 patients from ISRCTN68475405 in real moxibustion arm (moxibustion group) and 88 patients from ISRCTN26065334 in real laser moxibustion arm (laser group). Demographic characteristics and course of disease were similar between the two groups. Causal inference, using the doubly robust estimating approach to correct for bias due to baseline differences, showed that there was no statistically significant difference in the WOMAC pain, stiffness, and physical function between the two treatments at midterm, end of treatment, and 4 weeks after the end of treatment (P > 0.05). The exception was that there was statistically significantly more benefit associated with laser moxibustion compared with traditional moxibustion in physical function at the follow-up of 4 weeks after the end of treatment (P=0.006). There was no statistically significant difference in most SF-36 endpoints (P > 0.05) except that physical functioning (PF), mental health (MH), and bodily pain (BP) were statistically significantly better in the laser group than in the traditional moxibustion group at the follow-up of 4 weeks after the end of treatment (P = 0.005, 0.034, 0.002). The benefits of 10.6-μm infrared laser moxibustion and the traditional moxibustion for knee osteoarthritis were comparable in pain, stiffness, physical dysfunction, and in most of the quality of life subdimensions. The laser moxibustion might be more beneficial in terms of physical function, body pain, and mental health in the long term. RCTs directly comparing 10.6-μm laser moxibustion with traditional moxibustion are warranted.

Improving the referral pattern of patients with knee osteoarthritis to the orthopaedic surgeon: Development and evaluation of a new screening algorithm based on patient-reported data and radiographs

INTRODUCTION

Many patients with knee osteoarthritis referred to orthopaedic surgeons are not eligible for surgery and might benefit from being examined by other healthcare professionals. The objective of this study was to develop and test a screening algorithm to define relevant referral to the OS.

METHODS

Prior to clinical examination, 173 consecutive patients referred to the orthopaedic outpatient clinic completed questionnaires, and radiographic osteoarthritis severity was graded. The gold standard for relevant referral to an orthopaedic surgeon was based on actual treatment. The performance of the algorithm in predicting relevant referrals and total knee replacement (TKR) was assessed using sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV).

RESULTS

Referral to an orthopaedic surgeon was considered relevant in 65% (113/173) of patients. Sensitivity, specificity, PPV and NPV for predicting relevant referral to an orthopaedic surgeon were 0.70, 0.56, 0.76 and 0.48, respectively. The corresponding estimates for predicting TKR surgery were 0.92, 0.56, 0.55 and 0.92.

CONCLUSIONS

The algorithm was able to identify most patients relevant for referral to an orthopaedic surgeon, but less suitable for identifying those not relevant. The algorithm demonstrated excellent performance in predicting TKR surgery. With further development, this screening algorithm might contribute to improvement of the referral pattern in the orthopaedic outpatient clinic.

Implementing international osteoarthritis guidelines in primary care: uptake and fidelity among health professionals and patients

OBJECTIVE

This paper evaluates the implementation fidelity of a strategy and intervention used to implement osteoarthritis (OA) treatment recommendations in primary care. We also evaluate uptake of core treatment (patient information, exercise and referral to weight management) among OA patients.

DESIGN

A stepped-wedge cluster-randomised controlled study (RCT) in primary care. The study involved general practitioners (GPs), physiotherapists (PTs) and patients with hip and/or knee OA in six Norwegian municipalities (clusters). Workshops for general practitioners (GPs) and PTs represented the main implementation activity. Uptake of core treatment (patient education, exercise and weight management) was evaluated using self-reported data from the patient intervention and control group, analysed with logistic regression models. Fidelity was evaluated using six components representing adherence to the content and dose instructions in the implementation strategy and assessed against a-priori criteria for high adherence.

RESULTS

Data were collected from 40 GPs, 37 PTs and 393 OA patients. The patient-reported data showed statistically significant higher uptake for exercise, patient education and referral to support for weight reduction, among the intervention group compared to the control group (P < 0.05). Evaluation of fidelity showed high adherence to GP and PT workshop attendance and physiotherapy use, partly adherence to PT knowledge after workshops, and low adherence to exercise attendance, dose and progression instructions.

CONCLUSIONS

The implementation strategy and intervention successfully improved OA patients' access to physiotherapy and uptake of recommended core treatment. However, the strategy was less effective in providing exercise programs with sufficient dose and progression and in supporting patients' adherence to the exercise program.

The Pressing Need to Raise Awareness about Osteoarthritis Care among Elderly Females in Pakistan: A Cross-sectional Study

Introduction

Osteoarthritis (OA) is the single-most common cause of physical disability among adults. In view of its promising management modalities, an analysis of the level of awareness among the suspected individuals and their attitudes is crucial to assess the level of their implementation. This study aimed to do that among the female population in Karachi, Pakistan.

Methods

This cross-sectional study was conducted among 316 elderly females (≥60 years) in Karachi in 2018. Data were collected via a structured questionnaire, which included sections titled: demographics, knowledge, attitudes, and practices. Data were analyzed using the Statistical Package for Social Sciences (version 20.20, IBM, Armonk, New York, US), and chi-square tests were used to assess the connection between OA care and socioeconomic statuses. Mean and standard deviation were calculated for quantitative variables.

Results

A considerable portion (48%, n = 152) of the participants were from a lower socioeconomic background, and 51% of them had a history of joint pain. Significantly, 63% of the participants (n = 199) attributed their joint pain to age, while nearly half attributed it to their diet and exercise habits. A major segment (73%, n = 230) of the participants, irrespective of their socioeconomic backgrounds, had visited a doctor for their joint complaints. Around 65% of the participants said they would never undergo a knee-joint replacement, regardless of how worse their symptoms might get. Additionally, 36% of the participants were unsatisfied with their current treatment, while more than half of the participants said that medication would improve their condition.

Conclusions

Our results demonstrate a connection between the lack of awareness about OA and the factors negatively affecting its management. They also point towards areas that require focused efforts for better awareness.

[Utilization of individual out-of-pocket health services (IGeL) in persons with osteoarthritis in Germany : Results of a survey from the PROCLAIR study]

BACKGROUND

Little is known about the utilization of individual health services performed by a physician (IGeL) and the services and supplements provided outside a doctor's office (MuPaP) for osteoarthritis patients.

OBJECTIVES

The aims of this study are to analyze the use of osteoarthritis-specific IGeL and MuPaP as well as predictors for their utilization.

MATERIALS AND METHODS

For this cross-sectional study, claims data was used to identify all persons with hip, knee, or polyarticular osteoarthritis in 2014 (n = 657,807). A random sample (n = 8995) was sent a questionnaire about their usage of IGeL and MuPaP. Furthermore, the type of physicians conducting or recommending services was evaluated. Applying multivariable logistic regression, predictors associated with the utilization of IGeL, MuPaP, and overall individual health services were analyzed.

RESULTS

After validating the data and osteoarthritis diagnosis, 2363 persons were enrolled (mean age: 65.5 years, 72% female). In the last 12 months, 39% of patients had used at least one IGeL (MuPaP: 76%), with 86% being primarily performed by orthopedists (MuPaP: 88% patient self-motivated). Knee osteoarthritis was associated with increased utilization of IGeL. Having female gender, higher income, residence in Western Germany, higher disease burden, and lower satisfaction with the healthcare system were influences on the use of overall individual health services.

CONCLUSIONS

Since patients with high disease burden in particular tend to use these therapies with varying treatment success, detailed information, especially about the risks and existing evidence, should be a prerequisite for trustworthy doctor-patient relationships.

Quality of Care for Knee Osteoarthritis in Primary Care: A Patient's Perspective

OBJECTIVE

To describe the quality of osteoarthritis care in general practice from a patient's perspective and to identify novel associations between process quality indicators and patient-reported outcome and experience measures.

METHODS

For this study, 235 individuals with knee osteoarthritis completed a survey based on both process and outcome indicators. Process indicators were extracted from international guidelines and included the domains: diagnosis, self-management, treatment, and follow-up. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and RAND 36-item Short Form health survey (SF-36) were used to assess patient-reported outcomes. Patient-reported experience with care was evaluated with the European Task Force on Patient Evaluations of General Practice Care (EUROPEP) instrument. A series of multilevel regression analyses were then performed to analyze determinants at the patient level (i.e., age, sex, body mass index, and education) and associations between process and outcome indicators.

RESULTS

Overall, low adherence to the process indicators was observed (38%), particularly on informing patients about the importance of weight loss (24% [95% confidence interval (95% CI) 19-31]) or referring them for physical therapy (41% [95% CI 33-49]). Patients described their quality of life as moderate, with an overall score of 63% and 35% on the SF-36 and WOMAC surveys, respectively. Regarding the determinants, patients with a higher education level were better informed (odds ratio [OR] 3.4; P = 0.0003). Associations between process and outcome indicators were scarce, with the exception of patient satisfaction with care and use of nonsteroidal antiinflammatory drugs (NSAIDs) (OR 2.9; P = 0.0014).

CONCLUSION

Patients with knee osteoarthritis receive suboptimal conservative management. They report a moderate quality of life. This study confirms the evidence suggesting that NSAIDs are the backbone of osteoarthritis pain management but also adds evidence from a patient's perspective.

Physiotherapist as primary assessor for patients with suspected knee osteoarthritis in primary care-a randomised controlled pragmatic study

Background

In Swedish primary care, the healthcare process for patients with knee osteoarthritis (KOA) can be initiated by a physician or physiotherapist assessment. However, it is unclear how the different assessments affect the healthcare processes and patient reported outcomes over time. The purpose of this study was to examine the differences in health-related quality of life (HrQoL), adjusted for pain and physical function, for patients with KOA when the healthcare process is initiated by a physiotherapist assessment compared to a physician assessment in primary care.

Methods

An assessor-blinded randomised controlled pragmatic trial. Using a computer-generated list of random numbers, patients seeking primary care during 2013–2017 with suspected KOA were randomised to either a physiotherapist or physician for primary assessment and treatment. Data was collected before randomisation and at 3, 6, and 12-month follow-ups. Primary outcome was HrQoL using EuroQol 5 dimensions 3 levels questionnaire, index (EQ-5D-3L index) and a visual analogue scale (VAS) (EQ-5D-3L VAS); pain intensity was measured with VAS (0–100) and physical function measured with the 30-s chair stand test. Mixed effect model analyses compared repeated measures of HrQoL between groups. The significance level was p < 0.05 and data was applied with intention-to-treat.

Results

Patients were randomised to either a physiotherapist (n = 35) or physician (n = 34) for primary assessment. All 69 patients were included in the analyses. There were no significant differences in HrQoL for patients assessed by a physiotherapist or a physician as primary assessor (EQ-5D-3L index, p = 0.18; EQ-5D-3L VAS, p = 0.49). We found that HrQoL changed significantly 12 months after baseline assessment for all patients regardless of assessor (EQ-5D-3L index, p < 0.001; EQ-5D-3 L VAS, p = 0.0049). No adverse events or side effects were reported.

Conclusions

There were no differences in HrQoL, when adjusted for pain and physical function, for patients with KOA when the healthcare process was initiated with physiotherapist assessment compared to physician assessment in primary care. Both assessments resulted in significantly higher HrQoL at the 12-month follow-up. The results imply that physiotherapists and physicians in primary care are equally qualified as primary assessors.

An equine-assisted therapy intervention to improve pain, range of motion, and quality of life in adults and older adults with arthritis: A randomized controlled trial

RESEARCH AIM

To compare equine-assisted therapy to exercise education on pain, range of motion, and quality of life in adults and older adults with arthritis.

BACKGROUND

Quality of life for adults and older adults is negatively impacted by arthritis pain, stiffness, and decreased function. Equine-assisted therapy provides unique movements to the rider's joints and muscles improving pain, range of motion, and quality of life and has improved outcomes in balance, gait, strength, functional mobility, and spasticity for older adults, stroke, spinal cord injury, and multiple sclerosis patients. No research has investigated the effects on adults and older adults with arthritis.

METHODS

Twenty adults and older adults with arthritis recruited from rheumatology clinics participated in a randomized controlled trial for six weeks. Participants and research assistants were blinded to assignment. Standardized valid and reliable instruments were used to measure pain, range of motion, and quality of life targeting back, knees, shoulders, and hips.

RESULTS

Mean age was 63.85 (SD 6.885, 53-75) years. Pain significantly improved in shoulders (p = 0.007), hips (p = 0.027), and back (p = 0.006), not knees (p = 0.061). Range of motion improved for back (p = 0.02), hips (p = 0.04), shoulders (p = 0.005) and not knees. Quality of life improved for upper limb (p = 0.002), lower limb (p = 0.021), and affect (p = 0.030), not social interaction and symptoms.

CONCLUSION

This randomized controlled trial provides evidence that equine-assisted therapy decreases pain, and improves range of motion, and quality of life for adults and older adults with arthritis. Further fully powered research with cost/benefit outcomes would be beneficial.

Efficacy and Safety of Honey Bee Venom (Apis mellifera) Dermal Injections to Treat Osteoarthritis Knee Pain and Physical Disability: A Randomized Controlled Trial

Objectives: To evaluate purified honey bee (Apis mellifera) venom (HBV) biotherapy for the treatment of osteoarthritis (OA) knee pain and physical function. Design and Patients: Five hundred and thirty-eight patients with Kellgren/Lawrence grade 1-3 radiographic knee OA and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score ≥2 were randomized 1:2 to either control ("histamine") or HBV in this double-blind study. Interventions: After a dose escalation period, patients received 12 weekly dermal injections of control ("histamine") or HBV. At each of the 12 weekly visits, a set of 15 dermal injections (each containing 2.75 μg histamine or 100 μg HBV) were administered at prespecified acupuncture points (5 on each knee: knee top, eye-1 medial, eye-2 lateral, ST 34, BL 40 and 5 near the spinous processes: BL 19, 21, 23, 25, and 27). Outcome Measures: Assessments included WOMAC pain and physical function subscales, visual analog scale (VAS), patient global assessment (PGA), and physician global assessment (PhGA). Rescue medication use (acetaminophen) and routine safety parameters were monitored. Results: HBV biotherapy demonstrated a highly significant improvement over control in WOMAC pain score after 12 weeks (1.1 U mean difference; confidence interval [95% CI]: 0.3-2.0; analysis of covariance [ANCOVA] p = 0.0010 with baseline as covariate) that was also sustained 4 weeks post-treatment. Furthermore, WOMAC physical function was significantly improved over control with HBV (3.1 U mean difference; 95% CI: 0.3-5.9; ANCOVA p = 0.0046), and sustained 4 weeks post-treatment. VAS scores were significantly improved with HBV versus control, as well as PGA and PhGA evaluations, which showed that patients responded more favorably ("very good/good") to their overall OA condition (82.0% vs. 62.4% [p = 0.0001] and 82.1% vs. 54.9% [p = 0.0015], respectively). Use of rescue acetaminophen was similar between the groups (77%-78% of patients). HBV was associated with higher incidence of injection site reactions (<5%); however, the overall safety profiles were comparable between the treatment groups. Conclusions: This phase 3 trial demonstrated that HBV biotherapy resulted in significant improvements in knee OA pain and physical function.

Identifying and Prioritizing Clinical Guideline Recommendations Most Relevant to Physical Therapy Practice for Hip and/or Knee Osteoarthritis

BACKGROUND

Physical therapists are key providers of conservative management for hip and/or knee osteoarthritis (OA), yet not all guideline recommendations are tailored to their scope of practice.

OBJECTIVE

To identify and prioritize the most important recommendations relevant to physical therapy practice for hip and/or knee OA.

METHODS

International physical therapists (n = 132) were invited to participate in an online modified Delphi survey, followed by a priority-ranking exercise. A total of 63 recommendations were extracted from 2 recent high-quality clinical guidelines. In 3 Delphi rounds, the panel identified those recommendations they considered to be most relevant to physical therapy practice for hip and knee OA. Any new recommendations were ascertained. For a recommendation to be included, at least 70% of respondents had to rate the recommendation as 7 or above on a numeric rating scale (0 is not important and 10 is extremely important). The panel prioritized recommendations that remained after the final round using decision-making software.

RESULTS

Of 132 therapists from 14 countries, 62 completed round 1, 52 completed round 2, 45 completed round 3, and 35 completed the priority-ranking exercise. From an initial list of 70 potential recommendations (including 7 new recommendations), 30 were included in the priority-ranking exercise. The top recommendations were related to providing education and prescribing exercise and weight loss as core treatments, followed by individualized OA assessment and treatment and communication strategies.

CONCLUSION

This study identified and ranked the most important recommendations relevant to physical therapy practice for hip and/or knee OA. J Orthop Sports Phys Ther 2019;49(7):501-512. doi:10.2519/jospt.2019.8676.

A comparison of the effects of electroacupuncture vs transcutaneous electrical nerve stimulation for pain control in knee osteoarthritis: A protocol for network meta-analysis of randomized controlled trials

BACKGROUND

Knee osteoarthritis (KOA), the most common type of osteoarthritis, is a chronic degenerative joint disease accompanied by pain and functional limitation for the elderly. The 2 nonpharmacologic approaches, electroacupuncture (EA) and transcutaneous electrical nerve stimulation (TENS), are considered beneficial in relieving KOA pain, however, the current conclusions are controversial. Furthermore, no direct or indirect meta-analyses between EA and TENS have been reported for the pain relief of KOA patients.

METHODS

PubMed, EMBASE, Cochrane library, Web of Science, CNKI, VIP, Wan Fang will be systematically searched their inception to May 2018. Randomized controlled trials that compared the effect of EA and TENS on pain control in knee osteoarthritis will be included. The primary outcome was the knee pain levels, and secondary outcome was the comprehensive indicators. Risk of bias assessment of the included studies will be performed according to the Cochrane risk of bias tool. The pairwise and network meta-analysis will be performed by STATA 14.0 software.

RESULTS

This study is ongoing and will be submitted to a peer-reviewed journal for publication.

CONCLUSION

This study will provide comprehensive evidence on the effects of EA and TENS for pain control in knee osteoarthritis.

Descriptions of movement experiences in the Body Awareness Rating Scale - Movement Quality and Experience evaluation. A qualitative study of patients diagnosed with hip osteoarthritis

Background: Patients' access to movement experiences is implemented in the evaluation tool Body Awareness Rating Scale - Movement Quality and Experience, with its two intertwined parts: 1) the physiotherapist's observations of movement quality; and 2) the patient's descriptions of immediate movement experiences.Objective: To study movement experiences and reflections described by patients diagnosed with hip osteoarthritis when guided to explore simple daily-life movements in this particular evaluation context.Design: An explorative qualitative study with open-ended questions following each of the 12 movements integrated into the evaluation.Methods: 35 participants diagnosed with hip osteoarthritis were included; 28 women and 7 men, aged 23-78 years. Their descriptions were audiotaped, transcribed verbatim and analyzed in accordance with qualitative content analysis.Results: The patients described experiences of a dynamic adaptation of movement strategies based on sensations from the moving body. Two interrelated categories of movement awareness were identified: 1) Experienced movement challenges, including three sub-categories; a) Lack of contact, b) Movement changed by symptoms, and c) Compensational movement habits, and 2) Movement components promoting well-being, including three sub-categories; a) Integrating balance, breathing and awareness into movement, b) Small, simple, soft and safe movements, and c) A taste of own movement resources for daily life.Conclusions: The Body Awareness Rating Scale - Movement Quality and Experience provides a platform for patients to become aware of and describe their movement habits and resources in own words, intertwined with the physiotherapist movement observations. Derived descriptions reflect a patient perspective to be implemented in therapy.

Effects of Covertly Measured Home Exercise Adherence on Patient Outcomes Among Older Adults With Chronic Knee Pain

BACKGROUND

Assessment of home exercise adherence and the degree to which adherence influences changes in patient outcomes is limited by the use of self-reported measures.

OBJECTIVES

To determine the relationship between adherence to a home strengthening program, covertly measured by accelerometers in ankle cuff weights, and changes in self-reported pain, physical function, and knee extensor strength among people with chronic knee pain.

METHODS

This is a secondary analysis of data from a clinical measurement study in 54 adults, aged 45 years or older, with chronic knee pain who completed a 12-week, home-based quadriceps-strengthening program. A triaxial accelerometer was concealed in the ankle cuff weight used for exercises to assess exercise adherence. Associations between exercise adherence and changes in pain and function (measured using the Western Ontario and McMaster Universities Osteoarthritis Index) and peak isometric knee extensor strength were examined using mixed-effects and linear regression models and fractional polynomials.

RESULTS

Exercise adherence declined from a median of 90% (interquartile range, 70%-100%) in weeks 0 to 2 to 65% (interquartile range, 25%-90%) in weeks 10 to 12. Significant improvements were observed in knee pain (mean change, -3.2 units; 95% confidence interval [CI]: -2.4, -3.9 units), function (mean change, -10.1 units; 95% CI: -7.8, -12.4 units), and knee extensor strength (mean change, 0.34 Nm/kg; 95% CI: 0.26, 0.42 Nm/kg) across the group over the same period. Exercise adherence was not associated with changes in pain, function, and knee extensor strength over 2-week periods or over the entire 12 weeks.

CONCLUSION

Covertly measured adherence to a home strengthening program was not associated with changes in patient outcomes. These findings challenge the notion that greater exercise adherence leads to greater improvement in patient outcomes during a short-term intervention.

Physical Therapists' Falls Prevention Knowledge, Beliefs, and Practices in Osteoarthritis Care: A National Cross-Sectional Study

OBJECTIVE

To investigate physical therapists' knowledge, beliefs, and current practices around falls prevention in osteoarthritis (OA) care.

METHODS

Currently registered, practicing Australian physical therapists who care for patients with hip and/or knee OA were invited to participate in this cross-sectional study. A comprehensive online survey was used to collect data that were analyzed descriptively or using chi-square tests; free-text responses were classified into key themes for analysis.

RESULTS

Complete responses were received from 370 eligible physical therapists, with broad representation across Australian states and practice settings. Participants worked in public and private hospitals, community health centers, private practices, and aged-care facilities. The sample ranged from new graduates to experienced physical therapists (47% had practiced ≥11 years). Despite the majority having specific training or access to educational resources, physical therapists reported only moderate confidence in assessing falls risk (median 7 [interquartile range (IQR) 6-8]; range 0 [not at all confident] to 10 [extremely confident]) and delivering falls prevention care (median 7 [IQR 6-8]). While most participants asked about falls history (88%), only 39% used falls-risk screening tools, and of these, relatively few used appropriate tools. Time constraints (including competing clinical priorities) were the most frequently perceived barrier to including falls prevention activities within OA care.

CONCLUSION

This national snapshot of contemporary OA practice has revealed clear opportunities for optimizing clinician confidence and skills to facilitate the uptake of best-practice falls prevention strategies. Improving practice in this area may yield substantial benefits to patients and the health system if more falls can be prevented.

Single intra-articular injection of lightly cross-linked hyaluronic acid reduces knee pain in symptomatic knee osteoarthritis: a multicenter, double-blind, randomized, placebo-controlled trial

PURPOSE

The primary objective was to demonstrate the safety and effectiveness of Monovisc™ in the relief of joint pain in patients with idiopathic knee OA compared to saline injection. It was hypothesized that patient success, defined as ≥ 50% improvement from baseline and ≥ 20 mm absolute improvement from baseline in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) visual analog scale (VAS) pain score, would be greater in the Monovisc™ group compared to the Saline control group.

METHODS

In this multicenter, double-blind, randomized, placebo-controlled trial, patients with idiopathic, symptomatic, knee OA were randomized to either 4 ml single injection of Monovisc™ or 4 ml injection of 0.9% saline. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was used to assess patient outcomes at 2, 4, 8, 12, 20, and 26 weeks post-injection. The primary effectiveness endpoint was a 50% improvement and ≥ 20 mm improvement from baseline in the WOMAC pain through 26 weeks. Secondary outcome measures included a ≥ 20 mm improvement from baseline on the WOMAC physical function, patient global assessment, evaluator global assessment, and knee range of motion.

RESULTS

369 patients (154 male, 215 female) were randomized to either Monovisc™ or saline. The Monovisc™ group had a significantly greater rate of patient success (e.g. ≥ 50% improvement and ≥ 20 mm absolute improvement from baseline in the WOMAC pain through Week 26) compared to saline (p = 0.043).

CONCLUSIONS

Monovisc™, a single-injection intra-articular HA device, is a safe and effective treatment for providing a clinically meaningful reduction in knee pain within 2 weeks. The results of this study support the use of a single injection of hyaluronic acid (Monovisc™) for patients with symptomatic knee OA in patients older than 45 years, as a safe and effective alternative for patients who may want an alternative treatment modality or may not be candidates for partial or total knee replacement.

Non-steroidal anti-inflammatory drug effects on renal and cardiovascular function: from physiology to clinical practice

Excessive or inappropriate use of non-steroidal anti-inflammatory drugs can affect cardiovascular and renal function. Non-steroidal anti-inflammatory drugs, both non-selective and selective cyclooxygenase 2 inhibitors, are among the most widely used drugs, especially in the elderly, with multiple comorbidities. Exposition to a polypharmacy burden represents a favourable substrate for the onset of non-steroidal anti-inflammatory drug-induced deleterious effects. Cardiovascular and renal issues concerning the occurrence of myocardial infarction, atrial fibrillation, heart failure and arterial hypertension, as well as acute or chronic kidney damage, become critical for clinicians in their daily practice. We discuss current available knowledge regarding prostanoid physiology in vascular, cardiac and renal systems, pointing out potential negative non-steroidal anti-inflammatory drug-related issues in clinical practice.

Evaluation of a health trainer–led service for people with knee, hip and back pain

Aims:

Chronic knee, hip and back pain is extremely prevalent. Management guidelines emphasise maintaining physical activity and healthy weight to reduce pain and improve physical and mental wellbeing. Unfortunately, few people receive support to make lifestyle changes. We evaluated whether a health trainer—led ‘joint pain advice’ (JPA) service delivering person-centred lifestyle coaching was feasible, acceptable and effective for people with knee, hip and back pain.

Methods:

Feasibility of delivering a JPA service was assessed by documenting whether the health trainers could deliver JPA and its uptake. Nine health trainers delivered JPA. Participants were offered up to four appointments. At each appointment, health trainers gave people information about their condition, co-developed care plans, suggested self-management strategies and used behavioural change techniques (motivational interviewing, goal-setting and action planning) to increase physical activity and reduce body weight. Pain, function, physical activity and body mass index (BMI) were collected at baseline, 3 weeks, 6 weeks and 6 months. Focus groups captured people’s opinions of the service’s effectiveness, acceptability and usefulness.

Results:

Of the 105 people who enquired about JPA, 85 (81%) used the service, after which their physical activity and function improved, and pain, use of analgesia and BMI decreased. They felt more knowledgeable and better motivated to adopt and maintain healthier behaviours. They attributed these improvements to the JPA service, because of its better consultations and collaborative holistic approach. Only a minority attended all four appointments because they felt they received sufficient advice from the initial appointments. The health trainers gained knowledge and skills to support clients with musculoskeletal conditions.

Conclusions:

Using a holistic, patient-centred approach, health trainers can deliver lifestyle advice to people with chronic knee, hip or back pain safely, effectively and efficiently. The service was popular with recipients and health trainers, and helped people adopt healthier lifestyles that lead to reduced pain and other clinical improvements.

Effect of liraglutide on body weight and pain in patients with overweight and knee osteoarthritis: protocol for a randomised, double-blind, placebo-controlled, parallel-group, single-centre trial

INTRODUCTION

With an increasing prevalence of citizens of older age and with overweight, the health issues related to knee osteoarthritis (OA) will intensify. Weight loss is considered a primary management strategy in patients with concomitant overweight and knee OA. However, there are no widely available and feasible methods to sustain weight loss in patients with overweight and knee OA. The present protocol describes a randomised controlled trial evaluating the efficacy and safety of the glucagon-like peptide-1 receptor agonist liraglutide in a 3 mg/day dosing in patients with overweight and knee OA.

METHODS AND ANALYSIS

150 volunteer adult patients with overweight or obesity and knee OA will participate in a randomised, double-blind, placebo-controlled, parallel-group and single-centre trial. The participants will partake in a run-in diet intervention phase (week -8 to 0) including a low calorie diet and dietetic counselling. At week 0, patients will be randomised to either liraglutide 3 mg/day or liraglutide placebo 3 mg/day for 52 weeks as an add-on to dietetic guidance on re-introducing regular foods and a focus on continued motivation to engage in a healthy lifestyle. The co-primary outcomes are changes in body weight and the Knee Injury and Osteoarthritis Outcome Score pain subscale from week 0 to week 52.

ETHICS AND DISSEMINATION

The trial has been approved by the regional ethics committee in the Capital Region of Denmark, the Danish Medicines Agency and the Danish Data Protection Agency. An external monitoring committee (The Good Clinical Practice Unit at Copenhagen University Hospitals) will oversee the trial. The results will be presented at international scientific meetings and through publications in peer-reviewed journals.

Associations of Joint Line Tenderness and Patellofemoral Grind With Long-Term Knee Joint Outcomes: Data From the Osteoarthritis Initiative

OBJECTIVE

To examine whether joint line tenderness and patellofemoral grind from physical examination were associated with cartilage volume loss, worsening of radiographic osteoarthritis, and the risk of total knee replacement.

METHODS

This study examined 4,353 Osteoarthritis Initiative participants. For each measurement of joint line tenderness and patellofemoral grind, the patterns were defined as no (none at baseline and at 1 year), fluctuating (present at either time point), and persistent (present at both time points). Cartilage volume loss and worsening of radiographic osteoarthritis over 4 years were assessed using magnetic resonance imaging and radiographs, and total knee replacement over 6 years was assessed.

RESULTS

A total of 35.0% of participants had joint line tenderness, and 15.8% had patellofemoral grind. Baseline patellofemoral grind, but not joint line tenderness, was associated with increased cartilage volume loss (1.08% per year versus 0.96% per year; P = 0.02) and an increased risk of total knee replacement (odds ratio [OR] 1.55 [95% confidence interval (95% CI) 1.11-2.17]; P = 0.01). While the patterns of joint line tenderness were not significantly associated with joint outcomes, participants with persistent patellofemoral grind had an increased rate of cartilage volume loss (1.30% per year versus 0.90% per year; P < 0.001) and an increased risk of total knee replacement (OR 2.10 [95% CI 1.30-3.38]; P = 0.002) compared with those participants without patellofemoral grind.

CONCLUSION

Patellofemoral grind, but not joint line tenderness, may represent a clinical marker associated with accelerated cartilage volume loss over 4 years and an increased risk of total knee replacement over 6 years. This simple clinical examination may provide clinicians with an inexpensive way to identify those at higher risk of disease progression who should be targeted for surveillance and management.

The Value of High-Frequency Repetitive Transcranial Magnetic Stimulation of the Motor Cortex to Treat Central Pain Sensitization Associated With Knee Osteoarthritis

Aim

Chronic pain associated with knee osteoarthritis may develop in connection with a maladaptive process of pain sensitization in the central nervous system. Repetitive transcranial magnetic stimulation (rTMS) has been proposed to treat various pain syndromes related to central sensitization phenomenon, but was never applied in the context of knee osteoarthritis.

Methods

A 71-year-old woman presenting clinical evidence of central sensitization of pain associated with left knee osteoarthritis underwent monthly sessions of rTMS delivered at 10 Hz over the right motor cortex.

Results

From the week following the third session, she began to improve on various clinical aspects, including pain. After 10 sessions (i.e., almost one year of follow-up), pain was reduced by 67%, especially regarding neuropathic components, while sleep disorders and fatigue also improved by 57–67%. The central sensitization inventory (CSI) score was reduced by 70%.

Conclusion

This observation suggests that high-frequency motor cortex rTMS could be a therapeutic option to treat neuropathic pain and psychological symptoms associated with central sensitization developing in the context of chronic osteoarthritis of the knee joint.

The effects of cryotherapy on pain and function in individuals with knee osteoarthritis: a systematic review of randomized controlled trials

OBJECTIVE

To investigate the effectiveness of cryotherapy on pain and physical function in knee osteoarthritis.

DATA SOURCES

An electronic search was performed up to February 2019 on PubMed/MEDLINE, EMBASE, CINAHL, Lilacs, Cochrane, Web of Science, Ibecs, and Scielo databases with keywords knee osteoarthritis and cryotherapy.

METHODS

Two authors independently performed the study selection. All languages and publication dates were considered. The PEDro scale was used to assess the methodological quality of the studies, and the body of evidence was analyzed and synthesized using the Grading of Recommendations, Assessment, Development, and Evaluation approach. The clinical relevance of the included studies was evaluated using the criteria proposed in the Cochrane Handbook for Systematic Reviews of Interventions.

RESULTS

Of the five studies, 202 subjects were included. All studies included participants with established knee osteoarthritis. The mean PEDro score was 4.20/10, and meta-analysis was not possible due to heterogeneity among the studies. The mean clinical relevance was 3/5. Only two studies were considered for analysis based on the GRADE approach, and low level of evidence was synthesized regarding the effectiveness of cryotherapy for pain management, knee stiffness, knee range of motion, and physical function. Application techniques, frequency, and duration did not affect outcomes.

CONCLUSIONS

There were insufficient primary studies to draw any conclusions about the effectiveness of cryotherapy on pain and physical function on individuals with knee osteoarthritis.

Can the use of proprioceptive knee braces have implications in the management of osteoarthritic knees: An exploratory study

BACKGROUND:

Use of proprioceptive knee braces to control symptomology by altering neuromuscular control mechanisms has been shown in patellofemoral pain. Although their potential in patients with knee osteoarthritis is vast, little research has examined their efficacy.

OBJECTIVES:

This study examines the effect of a proprioceptive knee brace on lower limb kinematics and kinetics in healthy participants and in participants with OA.

METHODS:

Thirteen healthy participants were asked to perform a 10-cm step-down task with and without a proprioceptive brace. Data were collected using a 10-camera Qualisys system. Individuals with osteoarthritis completed the Knee injury and Osteoarthritis Outcome Score before and after 4 weeks of intervention.

RESULTS:

During step-down reductions in knee maximum internal rotation, transverse range of movement, transverse plane angular velocity and maximum internal rotation angular velocity was seen. Ankle plantar flexion and inversion angular velocity decreased while inversion and maximum supination angular velocity increased. Improvements in Knee injury and Osteoarthritis Outcome Score were noted across all parameters with brace use.

CONCLUSION:

Positive changes in kinematic variables in multiple planes can be achieved with proprioceptive bracing alongside improved patient outcome. These changes occur at the knee but analysis of other weight bearing joints should not be overlooked in future studies. This study supports the concept of neuromuscular reinforcement and re-education through proprioceptive bracing and its application in the management in knee osteoarthritis.

CLINICAL RELEVANCE

Proprioception can alter symptoms and biomechanics embraced and adjacent lower limb joints. The results of this study highlights the potential uses of non-mechanical bracing in the treatment of osteoarthritis and other potential to bridge the osteoarthritis treatment gap. Furthermore, large-scale research is needed to match disease subset to brace type.

Quality and Usability of Arthritic Pain Self-Management Apps for Older Adults: A Systematic Review

Objective

To appraise the quality and usability of currently available pain applications that could be used by community-dwelling older adults to self-manage their arthritic pain.

Methods

A systematic review. Searches were conducted in App Store and Google Play to identify pain self-management apps relevant to arthritic pain management. English language pain management apps providing pain assessment and documentation function and pain management education were considered for inclusion. A quality evaluation audit tool based on the Stanford Arthritis Self-Management Program was developed a priori to evaluate app content quality. The usability of included apps was assessed using an established usability evaluation tool.

Results

Out of the 373 apps that were identified, four met the inclusion criteria. The included apps all included a pain assessment and documentation function and instructions on medication use, communication with health professionals, cognitive behavioral therapy-based pain management, and physical exercise. Management of mood, depression, anxiety, and sleep were featured in most apps (N = 3). Three-quarters (N = 3) of the apps fell below the acceptable moderate usability score (≥3), while one app obtained a moderate score (3.2).

Conclusions

Few of the currently available pain apps offer a comprehensive pain self-management approach incorporating evidence-based strategies in accordance with the Stanford Arthritis Self-Management Program. The moderate-level usability across the included apps indicates a need to consider the usability needs of the older population in future pain self-management app development endeavors.

Benefits of Resistance Training with Blood Flow Restriction in Knee Osteoarthritis

PURPOSE

Evaluate the effects of a low-intensity resistance training (LI-RT) program associated with partial blood flow restriction on selected clinical outcomes in patients with knee osteoarthritis (OA).

METHODS

Forty-eight women with knee OA were randomized into one of the three groups: LI-RT (30% one repetition maximum [1-RM]) associated (blood flow restriction training [BFRT]) or not (LI-RT) with partial blood flow restriction, and high-intensity resistance training (HI-RT, 80% 1-RM). Patients underwent a 12-wk supervised training program and were assessed for lower-limb 1-RM, quadriceps cross-sectional area, functionality (timed-stands test and timed-up-and-go test), and disease-specific inventory (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]) before (PRE) and after (POST) the protocol.

RESULTS

Similar within-group increases were observed in leg press (26% and 33%, all P < 0.0001), knee extension 1-RM (23% and 22%; all P < 0.0001) and cross-sectional area (7% and 8%; all P < 0.0001) in BFRT and HI-RT, respectively, and these were significantly greater (all P < 0.05) than those of LI-RT. The BFRT and HI-RT showed comparable improvements in timed-stands test (7% and 14%, respectively), with the latter showing greater increases than LI-RT. Timed-up-and-go test scores were not significantly changed within or between groups. WOMAC physical function was improved in BFRT and HI-RT (-49% and -42%, respectively; all P < 0.05), and WOMAC pain was improved in BFRT and LI-RT (-45% and -39%, respectively; all P < 0.05). Four patients (of 16) were excluded due to exercise-induced knee pain in HI-RT.

CONCLUSIONS

Blood flow restriction training and HI-RT were similarly effective in increasing muscle strength, quadriceps muscle mass, and functionality in knee OA patients. Importantly, BFRT was also able to improve pain while inducing less joint stress, emerging as a feasible and effective therapeutic adjuvant in OA management.

Evaluation of an E-Learning Training Program to Support Implementation of a Group-Based, Theory-Driven, Self-Management Intervention For Osteoarthritis and Low-Back Pain: Pre-Post Study

Background

By adaptation of the face-to-face physiotherapist-training program previously used in the Self-management of Osteoarthritis and Low back pain through Activity and Skills (SOLAS) feasibility trial, an asynchronous, interactive, Web-based, e-learning training program (E-SOLAS) underpinned by behavior and learning theories was developed.

Objective

This study investigated the effect of the E-SOLAS training program on relevant outcomes of effective training and implementation.

Methods

Thirteen physiotherapists from across Ireland were trained via E-SOLAS by using mixed methods, and seven physiotherapists progressed to implementation of the 6-week group-based SOLAS intervention. The effectiveness of E-SOLAS was evaluated using the Kirkpatrick model at the levels of reaction (physiotherapist engagement and satisfaction with E-SOLAS training methods and content), learning (pre- to posttraining changes in physiotherapists’ confidence and knowledge in delivering SOLAS content and self-determination theory-based communication strategies, administered via a SurveyMonkey questionnaire), and behavior (fidelity to delivery of SOLAS content using physiotherapist-completed weekly checklists). During implementation, five physiotherapists audio recorded delivery of one class, and the communication between physiotherapists and clients was assessed using the Health Care Climate Questionnaire (HCCQ), the Controlling Coach Behaviour Scale (CCBS), and an intervention-specific measure (ISM; 7-point Likert scale). A range of implementation outcomes were evaluated during training and delivery (ie, acceptability, appropriateness, feasibility, fidelity, and sustainability of E-SOLAS) using a posttraining feedback questionnaire and individual semistructured telephone interviews.

Results

With regard to their reaction, physiotherapists (n=13) were very satisfied with E-SOLAS posttraining (median 5.0; interquartile range 1.0; min-max 4.0-5.0) and completed training within 3-4 weeks. With regard to learning, there were significant increases in physiotherapists’ confidence and knowledge in delivery of all SOLAS intervention components (P<.05). Physiotherapists’ confidence in 7 of 10 self-determination theory-based communication strategies increased (P<.05), whereas physiotherapists’ knowledge of self-determination theory-based strategies remained high posttraining (P>.05). In terms of behavior, physiotherapists delivered SOLAS in a needs supportive manner (HCCQ: median 5.2, interquartile range 1.3, min-max 3.7-5.8; CCBS: median 6.6, interquartile range 1.0, min-max 5.6-7.0; ISM: median 4.5, interquartile range 1.2, min-max 2.8-4.8). Fidelity scores were high for SOLAS content delivery (total %mean fidelity score 93.5%; SD 4.9%). The posttraining questionnaire and postdelivery qualitative interviews showed that physiotherapists found E-SOLAS acceptable, appropriate, feasible, and sustainable within primary care services to support the implementation of the SOLAS intervention.

Conclusions

This study provides preliminary evidence of the effectiveness, acceptability, and feasibility of an e-learning program to train physiotherapists to deliver a group-based self-management complex intervention in primary care settings, which is equivalent to face-to-face training outcomes and would support inclusion of physiotherapists in a definitive trial of SOLAS.

What does best practice care for musculoskeletal pain look like? Eleven consistent recommendations from high-quality clinical practice guidelines: systematic review

OBJECTIVES

To identify common recommendations for high-quality care for the most common musculoskeletal (MSK) pain sites encountered by clinicians in emergency and primary care (spinal (lumbar, thoracic and cervical), hip/knee (including osteoarthritis [OA] and shoulder) from contemporary, high-quality clinical practice guidelines (CPGs).

DESIGN

Systematic review, critical appraisal and narrative synthesis of MSK pain CPG recommendations.

ELIGIBILITY CRITERIA

Included MSK pain CPGs were written in English, rated as high quality, published from 2011, focused on adults and described development processes. Excluded CPGs were for: traumatic MSK pain, single modalities (eg, surgery), traditional healing/medicine, specific disease processes (eg, inflammatory arthropathies) or those that required payment.

DATA SOURCES

Four scientific databases (MEDLINE, Embase, CINAHL and Physiotherapy Evidence Database) and four guideline repositories.

RESULTS

6232 records were identified, 44 CPGs were appraised and 11 were rated as high quality (low back pain: 4, OA: 4, neck: 2 and shoulder: 1). We identified 11 recommendations for MSK pain care: ensure care is patient centred, screen for red flag conditions, assess psychosocial factors, use imaging selectively, undertake a physical examination, monitor patient progress, provide education/information, address physical activity/exercise, use manual therapy only as an adjunct to other treatments, offer high-quality non-surgical care prior to surgery and try to keep patients at work.

CONCLUSION

These 11 recommendations guide healthcare consumers, clinicians, researchers and policy makers to manage MSK pain. This should improve the quality of care of MSK pain.

Educational outreach visits to improve knee osteoarthritis management in primary care

BACKGROUND

Knee osteoarthritis is a common problem, but often underdiagnosed and undertreated in primary care as compared to evidence-based guidelines. Educational outreach visits are an effective strategy to improve guideline adherence, but its contribution to knee osteoarthritis management is largely unknown. The aim of this study was to evaluate the overall effectiveness of educational outreach visits on process quality indicators for knee osteoarthritis management, more specifically on the referral for physical therapy.

METHODS

An educational intervention study, non-randomized and controlled, was designed for general practitioners (GPs) in Belgium. During four months, 426 GPs were visited by academic detailers and allocated to the intervention group. The control group was selected from GPs not visited by academic detailers during the study period. Six months post-intervention, both groups received a questionnaire with two case-vignettes to measure the effectiveness of the educational outreach. Outcomes were assessed with a Belgian set of quality indicators for knee osteoarthritis management and focused on the number of prescriptions for appropriate physical therapy (i.e. muscle strengthening, aerobic, functional or range of motion exercises) and the adherence to eight additional quality indicators related to knee osteoarthritis management. For the analysis, multivariable logistic regression models were used and Generalized Estimating Equations to handle the correlation between the multiple results per GP.

RESULTS

The intervention group showed a tendency to prescribe more frequently at least one appropriate physical therapy for a case (43.8%), compared to the control group (31.3%, p = 0.057). Muscle strengthening exercises were the most frequently prescribed therapy with 37.0% in the intervention versus 26.9% in the control group. The adherence to the other quality indicators showed no significant difference between the intervention and control group and varied between 8.9 and 100% in the intervention group.

CONCLUSIONS

This intervention did not alter significantly the adherence to quality indicators and in particular the probability of prescribing physical therapy. To change general practitioners' prescription behavior, more extensive or combined interventional approaches seem warranted.

Osteoarthritis year in review 2018: rehabilitation and outcomes

OBJECTIVE

Conduct a systematic review of systematic reviews and randomised controlled trials (RCTs) from the past year evaluating rehabilitation for people with osteoarthritis, and provide narrative synthesis of findings focused on core recommended treatments for osteoarthritis (exercise, education, biomechanical interventions, weight loss).

DESIGN

A comprehensive search strategy was used to search PubMed, EMBASE and Cochrane databases (16^th May 2017 to 22^nd March 2018). Search terms included 'osteoarthritis', 'rehabilitation', 'systematic review', and 'randomised controlled trial'. Inclusion criteria were: (1) RCT, or systematic review of randomised clinical trials (RCTs); (2) human participants with osteoarthritis (any joint); (3) evaluation of rehabilitation intervention; and (4) at least one patient-reported measure. Methodological quality was evaluated using the Assessment of Multiple Systematic Reviews (AMSTAR) tool (systematic reviews) and PEDro rating scale (RCTs). Narrative synthesis mapped findings to core recommendations from existing osteoarthritis clinical guidelines.

RESULTS

From 1994 records, 13 systematic reviews and 36 RCTs were included. 73% of these evaluated knee osteoarthritis (36 studies). The remaining studies evaluated hand osteoarthritis (6 studies), hip, hip/knee and general osteoarthritis (each 2 studies), and neck osteoarthritis (1 study). Exercise was the most common intervention evaluated (31%). Updated recommendations for exercise prescription and preliminary guidance for psychological interventions are provided.

CONCLUSION

Level 1 and 2 osteoarthritis rehabilitation literature continues to be dominated by knee osteoarthritis studies. Consistent with current clinical guidelines, exercise should be a core treatment for osteoarthritis, but future studies should ensure that exercise programs follow published dose guidelines. There is a clear need for research on rehabilitation for hip, hand, foot/ankle, shoulder and spine osteoarthritis.

Active viscosupplements for osteoarthritis treatment

OBJECTIVE

Osteoarthritis is a chronic, painful and disabling disease which prevalence is increasing in developing countries. Patients with osteoarthritis present a reduced synovial fluid viscoelasticity due to a reduction in concentration and molecular weight of hyaluronic acid. Currently, the main treatment used to restore the compromised rheological properties of synovial fluid is the viscosupplementation by hyaluronic acid injections that can be combined with oral anti-inflammatory drugs for pain relief. Combination of viscosupplements with chemical agents or drugs is emerging as a new strategy to provide a double action of synovial fluid viscoelasticity recovery and the therapeutic effect of the bioactive principle.

METHODS

In this review, we present the latest research on the combination of viscosupplements with active molecules. We conducted a literature review of articles published in different web search engines and categorized according to the active molecule introduced into the viscosupplement.

RESULTS

Generally, the introduction of anti-inflammatory molecules have shown to improve pain relief although some cytotoxicity has been demonstrated especially for non-steroidal anti-inflammatory drugs. Other molecules such as antioxidant or disease modifying osteoarthritis drugs have been reported to improve viscosupplementation action. Drug delivery systems combined with hyaluronic acid could enhance the activity of the encapsulated molecules and provide better control over the drug release. Finally, biological approaches such as the use of stem cells or platelet-rich plasma seem to be the most promising strategies for cartilage recovery.

CONCLUSIONS

Combination therapy of viscosupplements with therapeutic agents, drug delivery systems or regenerative therapies can improve viscosupplementation outcome in terms of pain relief and joint functionality. However, further research is needed in order to reach more conclusive results.

Who seeks physiotherapy or exercise treatment for hip and knee osteoarthritis? A cross-sectional analysis of the English Longitudinal Study of Ageing

OBJECTIVES

To determine the characteristics of individuals with hip and/or knee osteoarthritis who are recommended to seek physiotherapy or exercise treatment, and to explore which people are more or less likely to follow such recommendations.

METHODS

All data were obtained from Wave 4 of the English Longitudinal Study of Ageing (ELSA) cohort (2008-2009), a prospectively collected community-based dataset. Eligibility was justified by a patient-reported diagnosis of hip and/or knee osteoarthritis with a visual analog scale (VAS) pain score of 1 or above. Data were collected from a self-completed questionnaire and nurse assessment visit. Prevalence of being recommended to physiotherapy or exercise (or not) and then the actioning of this recommendation (or not) were calculated and presented as 95% confidence intervals (CI). Data on characteristics of those recommended (or not) were explored using univariate analyses and then a forward selection logistic regression model.

RESULTS

In total, 1262 and 1877 individuals with hip and/or knee osteoarthritis pain were analyzed. This included 41% (95% CI: 0.38-0.44) who had been recommended to seek physiotherapy or exercise treatment. Subsequently, 83% of those recommended sought these treatments. Individuals who presented with isolated knee pain, those who reported "fair" self-reported general health and were younger had a greater chance of being recommended for physiotherapy or exercise treatment, respectively (P ≤ 0.02).

CONCLUSION

Encouragement should be given to formal and informal care providers of older people to highlight this inequality. This may then improve current and future access to evidence-based treatments for this population.

Prevalence and healthcare usage of knee pain in South Australia: a population-based study

BACKGROUND

It is known that South Australia (SA) has the highest rate of knee arthroscopy use of any state in Australia; however, Level 1 evidence demonstrates that knee arthroscopy in patients with uncomplicated knee osteoarthritis confers no benefit. In SA, which patients are presenting with knee pain and what treatments are they receiving?

AIMS

To determine the prevalence, persistence and treatment modalities of knee pain in SA.

METHODS

This study analysed data from the North-West Adelaide Health Study (1999-2015), a longitudinal, population-based cohort study of people aged 18 years and over (n = 4060), initially randomly selected from the north-west region of Adelaide, SA. It incorporated clinic assessments, self-completed questionnaires and telephone interviews to collect demographic, anthropometric and biochemical data over four main stages (1, 2, 3 and North-West 15 (NW15)). Data were linked to Medical Benefits Scheme data.

RESULTS

In stages 3 and NW15 of the North-West Adelaide Health Study, 30-35% of participants reported knee pain (n = 803, 452). Demographic variables associated with knee pain included older age and lower educational level, while risk factors included obesity and high waist circumference. In the 12 months preceding NW15, 33% of participants with knee pain/stiffness consulted a general practitioner for their knee pain, 10.2% an orthopaedic surgeon, and 12.6% a physiotherapist. Between 2011 and 2015, 3.0% the cohort underwent a knee arthroscopy, and 3.1% underwent knee magnetic resonance imaging.

CONCLUSIONS

Knee pain affects large proportions of the SA population. Knee pain was persistent with underuse of non-pharmacological treatments and high use of specialist referral. These data support the need for a national strategy to manage osteoarthritis effectively.
