Significant improvements in pain after a six-week physiotherapist-led exercise and education intervention, in patients with osteoarthritis awaiting arthroplasty, in South Africa: a randomised controlled trial

Development of the intelligent knee osteoarthritis lifestyle app: a person-based approach

BACKGROUND

Knee osteoarthritis is one of the most prevalent long term health conditions globally. Exercise and physical activity are now widely recognised to significantly reduce joint pain, improve physical function and quality of life in patients with knee osteoarthritis. However, prescribed exercise without regular contact with a healthcare professional often results in lower adherence and poorer health outcomes. Digital mobile health (mHealth) technologies offer great potential to support people with long-term conditions such as knee osteoarthritis more efficiently and effectively and with relatively lower cost than existing interventions. However, there are currently very few mHealth interventions for the self-management of knee osteoarthritis. The aim of the present study was to describe the development process of a mHealth app to extend the support for physical activity and musculoskeletal health beyond short-term, structured rehabilitation through self-management, personalised physical activity, education, and social support.

METHODS

The development of the intelligent knee osteoarthritis lifestyle application intervention involved an iterative and interconnected process comprising intervention 'planning' and 'optimisation' informed by the person-based approach framework for the development of digital health interventions. The planning phase involved a literature review and collection of qualitative data obtained from focus groups with individuals with knee osteoarthritis (n = 26) and interviews with relevant physiotherapists (n = 5) to generate 'guiding principles' for the intervention. The optimisation phase involved usability testing (n = 7) and qualitative 'think aloud' sessions (n = 6) with potential beneficiaries to refine the development of the intervention.

RESULTS

Key themes that emerged from the qualitative data included the need for educational material, modifying activities to suit individual abilities and preferences as well as the inclusion of key features such as rehabilitation exercises. Following a user-trial further changes were made to improve the usability of the application.

CONCLUSIONS

Using a systematic person-based, development approach, we have developed the intelligent knee osteoarthritis lifestyle application to help people maintain physical activity behaviour. The app extends the support for physical activity and musculoskeletal health beyond short-term, structured rehabilitation through personalised physical activity guidance, education, and social support.

Influence of the intelligent knee osteoarthritis lifestyle app (iKOALA) on knee joint pain

BACKGROUND

The intelligent knee osteoarthritis lifestyle app (iKOALA) has been co-developed with target users to extend the support for physical activity (PA) and musculoskeletal health, beyond short-term structured rehabilitation, using personalised PA guidance, education, and social support. The purpose of this study was to assess the preliminary effectiveness and usability of the iKOALA digital intervention on indices of musculoskeletal (MSK) health, symptoms, and physical activity levels in a broad range of individuals with knee osteoarthritis (KOA) over 12 weeks to inform the design of a larger randomised controlled trial.

METHODS

Thirty-eight (33 female) participants living in the UK with a mean (SD) age of 58 (± 9) years diagnosed radiographically or clinically with KOA completed a 12-week user trial of the iKOALA. Participants completed an in-app physical activity questionnaire which intelligently recommended suitable strengthening and aerobic based activities to individuals. Throughout the trial, participants wore a physical activity monitor and were given access to functions within the app (physical activity (PA) reminders, information and education, symptom and PA tracking as well as social support forums) to support them in maintaining their PA plan. Participants completed a MSK questionnaire for chronic symptoms and quality of life (MSK-HQ) as well as an acute iKOALA symptoms questionnaire (confidence, fatigue, mood, pain during the day/night, sleep and ability to walk) in the week prior to starting and following completion of the trial.

RESULTS

Physical activity levels were consistent over the 12 weeks with total daily steps of 9102 (± 3514) in week 1, 9576 (± 4214) in week 6 and 9596 (± 3694) in week 12. Group mean changes in all iKOALA MSK symptom scores and the total MSK-HQ (pre 33.1 (7.6) vs. post 40.2 (7.6)) score improved significantly (p < .001, 95% CI [-8.89, -5.16]) over the 12-week period.

CONCLUSIONS

Physical activity levels were maintained at a high level throughout the 12 weeks. Significant improvements in mean MSK symptom scores and the total MSK-HQ score were also observed. Efforts to ensure more generalised reach amongst sex and socioeconomic status of the digital intervention in a randomised controlled clinical trial are warranted.

Effect of exercise therapy in patients with hip osteoarthritis: A systematic review and cumulative meta-analysis

Objective

To evaluate the existing evidence on the effect of exercise therapy in patients with hip osteoarthritis (OA) compared to no treatment and explore whether a further trial will change the current evidence.

Design

Systematic review and cumulative meta-analysis using randomized controlled trials (RCT) to determine the effect on pain and function post-treatment, and at 6-9 months after treatment. Standardized mean difference (SMD) ​≤ ​-0.37 was considered clinically worthwhile. Extended funnel plots were used to simulate the impact of a new trial on the pooled effect size of pain and function.

Results

18 RCTs were included. Post-treatment we found a beneficial effect of exercise therapy on pain (SMD -0.38, 95% Confidence Interval (CI): 0.55 to -0.22) and function (SMD -0.31, 95% CI -0.49 to -0.11). A beneficial effect of exercise therapy on pain (SMD -0.23, 95% CI: 0.41 to -0.05) and function (SMD -0.29, 95% CI: 0.45 to -0.12) was found 6-9 months after treatment. Most effect estimates were small, and it is unclear whether these are clinically meaningful. Extended funnel plots and a simulation of a new trial showed that only a new trial with a larger effect than the current pooled effect or a trial including 74,843 participants would change the pooled effect estimate from an unclear to a clearly clinically worthwhile effect.

Conclusions

We found a beneficial effect of exercise therapy on pain and function in hip OA. It is unlikely a new trial added to current evidence will change the conclusion.

The impact of waiting time for orthopaedic consultation on pain levels in individuals with osteoarthritis: a systematic review and meta-analysis

OBJECTIVE

Time spent waiting for access to orthopaedic specialist health services has been suggested to result in increased pain in individuals with osteoarthritis (OA). We assessed whether time spent on an orthopaedic waiting list resulted in a detrimental effect on pain levels in patients with knee or hip OA.

METHODS

We searched Ovid MEDLINE, EMBASE and EBSCOhost databases from inception until September 2021. Eligible articles included individuals with OA on an orthopaedic waitlist and not receiving active treatment, and reported pain measures at two or more time points. Random-effects meta-analysis was used to estimate the pooled effect of waiting time on pain levels. Meta-regression was used to determine predictors of effect size.

RESULTS

Thirty-three articles were included (n = 2,490 participants, 67 ± 3 years and 62% female). The range of waiting time was 2 weeks to 2 years (20.8 ± 18.8 weeks). There was no significant change in pain over time (effect size = 0.082, 95% CI = -0.009, 0.172), nor was the length of time associated with longitudinal changes in pain over time (β = 0.004, 95% CI = -0.005, 0.012). Body mass index was a significant predictor of pain (β = -0.043, 95% CI = -0.079, 0.006), whereas age and sex were not.

CONCLUSIONS

Pain remained stable for up to 1 year in patients with OA on an orthopaedic waitlist. Future research is required to understand whether pain increases in patients waiting longer than 1 year.

Non-pharmaceutical treatments to relieve pain or reduce opioid analgesic intake and improve quality of life after total hip replacement: a meta analysis

To reduce pain after total hip replacement (THR), researchers are interested in drug-free interventions. However, there is still a lack of consensus on their prevention efficacy. We performed a meta-analysis to evaluate the use of nonpharmaceutical interventions for postoperative pain management after THR. We searched the Cochrane Library, MEDLINE, EMBASE, Web of Science, PEDRO, and ClinicalTrials.gov databases for articles published between and 1991 and 2020. The main outcome measures were postoperative pain, opioid consumption, and quality of life (QoL). In total, 1,942 patients were studied. We found moderate evidence indicating postoperative pain relief measured by the Western Ontario and McMaster Universities Arthritis Index Scale, with mean differences (MDs) of -0.28 (95% confidence interval [CI], -0.49 to -0.07; P=0.01; I² =0%) within three months, -0.19 (95% CI, -0.40 to 0.02; P=0.07; I² =0%) between 3-6 months, and -0.13 (95% CI, -0.35 to 0.08; P=0.21; I² =0%) between 6-12 months. Additionally, we found that acupuncture therapy could reduce opioid analgesic consumption (MD, -0.98; 95% CI, -1.18 to -0.79; fentanyl [mg/h]; P<0.01; I² =72.2%) and significantly improve pain relief with an MD of 0.90 (95% CI, 0.47 to 1.33; P<0.01; I² =0%) measured using the visual analog scale. Electrotherapy slightly improved perceived pain with an MD of 0.22 (95% CI, -0.27 to 0.70; P=0.37; I² =0%). Moreover, moderate evidence has shown that preoperative exercises improve QoL. This meta-analysis suggested that continuous passive motion did not improve pain or QoL. Postoperative exercise was associated with pain relief and improved QoL. Acupuncture therapy after THR has been shown to reduce opioid analgesic consumption.

The effects of preoperative rehabilitation on pain and functional outcome after total knee arthroplasty: a meta-analysis of randomized controlled trials

Background

There have been controversial findings for the effectiveness of rehabilitation before operation after total knee arthroplasty (TKA). This study aimed to conduct an updated, comprehensive systematic review. On that basis, the review was to be combined with meta-analysis to measure the effects of rehabilitation before operation on functions and pain after TKA.

Methods

Articles were searched by using Central Register of Controlled Trials (CENTRAL), Web of Science, EMBASE, Cochrane, Pubmed, CNKI, Wanfang, Weipu and the Chinese Biomedical Database from the beginning to December 10, 2021. The major outcomes included pain, knee flexion and extension, as well as knee range of motion (ROM). Secondary outcomes included timed-up-and-go (TUG), 6-min walk, and patient-reported functional outcome (the Knee Injury and Osteoarthritis Outcome Score (KOOS) or Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)). Third outcomes included the length of hospital stay.

Results

Nineteen studies recruiting 1008 patients satisfied with the inclusion criteria. Significant difference was identified in knee flexion, TUG, KOOS (knee-associated life quality and functions in sports and recreation), as well as the length of hospital stay (P < 0.05). Insignificant statistical difference was identified in pain, 6-min walk, ROM, knee extension, KOOS (pain, symptoms and function of daily living) after TKA between the two groups. No difference was found between the groups in WOMAC.

Conclusions

Preoperative rehabilitation could significantly shorten hospital stay, whereas there is not any conclusive evidence of the improvement of postoperative functions. Accordingly, in-depth high-quality studies should be conducted to confirm the effectiveness of preoperative rehabilitation in patients having received TKA.

Effectiveness of Interventions Based on Pain Neuroscience Education on Pain and Psychosocial Variables for Osteoarthritis: A Systematic Review

Osteoarthritis (OA) is the most common joint condition. It affects more than 300 million people worldwide, who suffer from pain and physical disability. Objective: To determine the results of cognitive educational interventions for pain management and psychosocial variables in adults with OA. Method: A systematic review was conducted based on searches in MEDLINE, OVID, LILACS, Scopus, PEDro, OTseeker, The Cochrane Library, EBSCO, and Google Scholar. The search strategy included the main terms neuroscience education and osteoarthritis, without any re-strictions with regard to dates or study type (PROSPERO register CRD42021222763). Results: We included four articles that implemented the intervention in 1–6 sessions, addressing concepts related to goal orientation and providing strategies for understanding pain. The results suggest that there is an improvement between the groups (PNE) when compared, but this cannot necessarily be attributed to pain neuroscience education (PNE), as small effect sizes for variables such as pain catastrophizing and kinesiophobia were observed. The response in the modulation of acute pain following the surgical procedure may produce a variation in the responses and this may be mediated by medications. Conclusion: The study revealed an improvement in favor of the groups managed with PNE, although more studies documenting the topic are warranted.

Culture and musculoskeletal pain: strategies, challenges, and future directions to develop culturally sensitive physical therapy care

BACKGROUND

Pain experience has a multidimensional nature. Assessment and treatment recommendations for pain conditions suggest clinicians use biopsychosocial approaches to treat pain and disability. The current pain research is overwhelmingly skewed towards the study of biological and psychological factors including interventions, whereas, cultural factors are often ignored.

OBJECTIVE

The aims of this Masterclass is threefold: (1) to discuss cultural influences on pain, (2) to provide strategies for delivering appropriate pain education and exercises in culturally diverse people with chronic pain, and (3) to present challenges and future directions to clinicians and researchers.

DISCUSSION

Cultural factors have a relevant influence on the way individuals experience and manage health and illness. Thus, people with different cultural experience perceive, respond, communicate and manage their pain in different ways. In this aspect, the contents of pain education should be presented using different culturally appropriate examples, metaphors, images, and delivery methods that may enhance the impact of the message. Efforts should be made to produce and spread culturally adapted evidence-based materials and resources. In addition, a culturally sensitive approach may help to introduce patients to graded activities, so that they can apply these strategies in culturally acceptable and meaningful ways. Future studies should investigate the effectiveness of culturally-adapted interventions in pain-related outcomes in different pain conditions in patients with different cultural backgrounds.

Effectiveness of Isometric Exercise and Counseling on Level of Pain Among Patients With Knee Osteoarthritis

Introduction

Osteoarthritis (OA) is one of the emerging health issues in Asian countries in elderly population. Knee osteoarthritis (KOA) is a major age related public health issue characterized by progressive loss of articular cartilage resulting in pain, functional impairment, disability and diminished quality of life. The aim of this study was to assess the effectiveness of Isometric exercise and counseling on level of pain among patients with KOA.

Methods

Quantitative research approach and a quasi-experimental pretest-posttest control group research design was utilized. The study was conducted at MIOT hospital and Devadoss Hospital, Madurai, Tamil Nadu, India. Data was collected from a total of 200 patients with KOA, 100 in the study and 100 in the control group. These patients were clinically diagnosed to have Grade I, II and III KOA. The demographic variables and clinical profile were recorded for both groups. The self-administered WOMAC questionnaire was used to assess the level of pain of KOA patients. Post-test assessment was carried out on Day 15, Day 30, Day 60 and Day 90. The data was analyzed using SPSS windows 16.

Results

The comparison of level of pain between the study and control group has showed a remarkable reduction in level of pain among patients with KOA in the study group. The post-test level of pain in the study group was 14.9% (13.3% -16.5% with 95% CI) and was 2.1% (1.2% -3.0% with 95% CI) in the control group. It showed that the reduction in the level of pain was higher in the study group than the control group.

Conclusion

The study found that a 12-week Isometric exercise and counseling program has significantly reduced pain, stiffness and improved physical function. Therefore, the Isometric exercise and counselling should be adopted as a routine care in the hospitals treating patients with KOA.

Responders to Exercise Therapy in Patients with Osteoarthritis of the Hip: A Systematic Review and Meta-Analysis

The Outcome Measures in Rheumatology workgroup (OMERACT), together with the Osteoarthritis Research Society International (OARSI) developed the OMERACT-OARSI responder criteria. These criteria are used to determine if a patient with osteoarthritis (OA) ‘responds’ to therapy, meaning experiences a clinically relevant effect of therapy. Recently, more clinical OA trials report on this outcome and most OA trials have data to calculate the number of responders according to these criteria. A systematic review and meta-analysis were performed on the response to exercise therapy, compared to no or minimal intervention in patients with hip OA using the OMERACT-OARSI responder criteria. The literature was searched for relevant randomized trials. If a trial fit the inclusion criteria, but number of responders was not reported, the first author was contacted. This way the numbers of responders of 14 trials were collected and a meta-analysis on short term (directly after treatment, 12 trials n = 1178) and long term (6–8 months after treatment, six trials n = 519) outcomes was performed. At short term, the risk difference (RD) was 0.14 (95% confidence interval (CI) 0.06–0.22) and number needed to treat (NNT) 7.1 (95% CI 4.5–17); at long term RD was 0.14 (95% CI 0.07–0.20) and NNT 7.1 (95% CI 5.0–14.3). Quality of evidence was moderate for the short term and high for the long term. In conclusion, 14% more hip OA patients responded to exercise therapy than to no therapy.

Chronic non-cancer pain management in primary care

Chronic non-cancer pain is a common, often undiagnosed condition in primary care across the world, with prevalence rates between 20% and 40%. To effectively address this problem, the primary care practitioner needs to have an organised, comprehensive approach to diagnosing and managing these patients within a biopsychosocial framework, in collaboration with members of the interdisciplinary team. The aim of this article is to provide the primary care practitioner with up to date information on the management of chronic pain. A case study is introduced to raise awareness of some of the complexities of dealing with the problem. A series of key questions are raised that address the various levels of complexity. Current evidence is used to guide the reader through these questions, covering a wide area of pain research as it pertains to primary care. The article concludes with five practice points that link the literature to clinical practice.

State of the art: What have the pain sciences brought to physiotherapy?

Background

Pain is the most common reason for patients to seek help from a health care professional. In the past few decades, research has yielded gains in the Pain Sciences - multiple fields of scientific research that, when integrated, help to clarify what causes and influences human pain.

Objectives

In this article, we discuss the key areas in which the Pain Sciences have shifted the physiotherapy profession.

Method

A narrative review of the Pain Sciences literature was conducted. The review analyses how the Pain Sciences have influenced physiotherapy in several categories: assessment; clinical reasoning; treatment; research rigor and building the profile of the profession.

Results

Scientific research on pain has largely converged in support of three ‘game-changing’ concepts that have shifted the physiotherapy profession’s understanding and treatment of pain: (1) pain is not a signal originating from bodily tissues, (2) pain is not an accurate measure of tissue damage and (3) the plasticity of the nervous system means the nervous system itself is a viable target of treatment. These three concepts have influenced physiotherapy assessment and treatment approaches, and research design to consider pain mechanisms using patient-centred models.

Conclusion

The Pain Sciences have shifted physiotherapists’ assessment and treatment approaches and shifted the status of the physiotherapy profession. Ultimately the Pain Sciences have embedded interdisciplinary teams and expanded physiotherapy practice.

Clinical implications

We believe that the pain sciences should be embedded in undergraduate and postgraduate education and training of physiotherapists (including the three key concepts regarding pain) to benefit physiotherapists and their patients.

Career crescendo

Purpose

Research surrounding psychological capital (PsyCap) continues to expand as scholars and organizational leaders look to the strengths of positive organizational behavior (POB) and its effects in the workplace. Although previous research underscores connections between PsyCap and various organizational outcomes, there remains little research on its actual development. The purpose of this paper is to determine the efficacy of a six-week work-site intervention in improving PsyCap. The study included 49 individuals (n=32 assigned to the treatment group and n=17 to the comparison group). Using a pretest/posttest experimental design, the study showed that the intervention was efficacious in helping employees to develop greater PsyCap.

Design/methodology/approach

This study was part of a larger mixed methods design aimed at determining the efficacy of a work-site intervention in improving the PsyCap of employees. This design was chosen because it maximizes the strengths of both qualitative and quantitative methods while minimizing each of their weaknesses (Creswell and Plano Clark, 2007; Tashakkori and Teddlie, 1998). The specific mixed methods design implemented was the explanatory design using the participant selection model. This is a two-phase, sequential approach which began with a quantitative analysis and then drew upon those data to determine individuals who will be asked to participate in a follow-up study.

Findings

The purpose of this study was to determine the impact of a work-site intervention on the participants’ PsyCap in determining its developmental capacity. Previous studies have demonstrated strong correlations between PsyCap and many of the positive outcomes managers and supervisors desire for their employees –high productivity, low absenteeism, positive organizational citizenship, etc. (Luthans et al., 2013; Youseff and Luthans, 2007). With the results of the present study showing significantly greater improvement for the treatment group than their counterparts in the comparison group, it demonstrates that PsyCap can be developed and, consequently, these positive outcomes can accessed by a focused work-site intervention.

Originality/value

This paper builds on work already being done but focuses on the following significant gap in the literature: Can PsyCap be developed using work-site interventions? This study provides a compelling answer to that question and thus pushes the study of POB forward in its development.

A Systematic Review and Meta-Analysis of the Effectiveness of Psychological Interventions Delivered by Physiotherapists on Pain, Disability and Psychological Outcomes in Musculoskeletal Pain Conditions

OBJECTIVE

This systematic review and meta-analysis examined the effectiveness of physiotherapist delivered psychological interventions combined with physiotherapy on pain, disability, and psychological outcomes for patients with musculoskeletal pain conditions.

METHODS

The review was conducted in accordance with the (PRISMA) guidelines. Five databases were systematically searched for randomized controlled trials from inception to May 2016. Studies were required to compare a psychological intervention delivered by physiotherapists combined with physiotherapy to physiotherapy alone or usual care. Physiotherapists delivering the interventions must have undergone training by a psychologist or a health professional trained in the delivery of psychological interventions.

RESULTS

A total of 34 articles met the eligibility criteria, of those, 30 were suitable for meta-analysis. There was low to high quality evidence that physiotherapist delivered psychological intervention combined with physiotherapy decreased pain in the short (26 studies, mean difference=-0.37; 95% confidence interval [CI], -0.65 to -0.09) and long term (22 studies, mean difference=-0.38; 95% CI, -0.67 to -0.10) and decreased disability in the short term (29 studies, standardized mean difference =-0.14; 95% CI, -0.26 to -0.01). Effect sizes were small. Low to high quality evidence demonstrated small to medium effects for some psychological outcomes at short-term and long-term follow-ups.

DISCUSSION

The results indicate that psychological interventions delivered by physiotherapist show promise to improve health outcomes, particularly psychological outcomes, in musculoskeletal pain conditions.

Improvements in health-related quality of life and function in middle-aged women with chronic diseases of lifestyle after participating in a non-pharmacological intervention programme: A pragmatic randomised controlled trial

Background

Musculoskeletal diseases consume a large amount of health and social resources and are a major cause of disability in both low- and high-income countries. In addition, patients frequently present with co-morbid chronic diseases of lifestyle. The area of musculoskeletal disease is restricted by a lack of epidemiological knowledge, particularly in low- and middle-income countries.

Objectives

This pragmatic randomised controlled trial assessed the benefits of a 6-week physiotherapy intervention for middle-aged women with musculoskeletal conditions compared to usual care.

Method

A weekly 2-h educational programme utilising a workbook, discussion group and exercise class was presented for the intervention group, while the control group received usual care. The primary outcome was health-related quality of life. Parametric and non-parametric data were used to determine the equivalence between the groups.

Results

Twenty-two participants were randomised to the intervention and 20 to the control group. The control group demonstrated no within-group improvement in health-related quality of life items, compared to significant improvements in two items in the intervention group. The change in median utility score within the intervention group was twice as large as the change in the control group. With regard to self-efficacy, the intervention group demonstrated significant within-group changes in perceived management of fatigue and discomfort.

Conclusion

The positive impact of the intervention on the participants suggests that the programme should continue at the clinic in question, but should be presented at a more convenient time for participants who work, as recruitment to the study was less than anticipated. Primary health care systems in South Africa urgently need to put structures in place for effective management of the functional impact of chronic diseases of lifestyle and musculoskeletal conditions. It is time for physiotherapists and possibly other health care professionals to participate in the development of appropriate community level interventions to address the functioning and quality of life of individuals living with the diseases.

Physical Activity and Exercise Therapy Benefit More Than Just Symptoms and Impairments in People With Hip and Knee Osteoarthritis

Synopsis Osteoarthritis (OA) of the hip and knee is among the leading causes of global disability, highlighting the need for early, targeted, and effective treatment. The benefits of exercise therapy in people with hip and knee OA are substantial and supported by high-quality evidence, underlining that it should be part of first-line treatment in clinical practice. Furthermore, unlike other treatments for OA, such as analgesia and surgery, exercise therapy is not associated with risk of serious harm. Helping people with OA become more physically active, along with structured exercise therapy targeting symptoms and impairments, is crucial, considering that the majority of people with hip and knee OA do not meet physical activity recommendations. Osteoarthritis is associated with a range of chronic comorbidities, including type 2 diabetes, cardiovascular disease, and dementia, all of which are associated with chronic low-grade inflammation. Physical activity and exercise therapy not only improve symptoms and impairments of OA, but are also effective in preventing at least 35 chronic conditions and treating at least 26 chronic conditions, with one of the potential working mechanisms being exercise-induced anti-inflammatory effects. Patient education may be crucial to ensure long-term adherence and sustained positive effects on symptoms, impairments, physical activity levels, and comorbidities.
