Effects of non-pharmacological conservative treatment on pain, range of motion and physical function in patients with mild to moderate hip osteoarthritis. A systematic review

Does self-reported physical activity relate to physical function and walking ability in female patients with hip osteoarthritis? A cross-sectional multicenter study

BACKGROUND

The effectiveness of a high level of physical activity in maintaining physical function in patients with hip osteoarthritis has not been adequately examined.

OBJECTIVE

This study aimed to determine whether self-reported physical activity is associated with physical function and walking ability in female patients with hip osteoarthritis.

METHODS

This was a multicenter cross-sectional study. The dependent variables were the lower-limb range of motion and muscle strength, and walking ability. Self-reported physical activity was assessed according to the guidelines of the Japanese Ministry of Health, Labor, and Welfare. Multiple regression models were used to determine whether physical activity was significantly related to the dependent variables after adjusting for confounding factors (age, body mass index, hip pain, comorbidity, and severity of hip osteoarthritis).

RESULTS

A total of 167 participants were included in the study. Physical activity was associated with muscle strength in hip flexion (affected/unaffected, β = 0.18/β = 0.16), abduction (β = 0.19/β = 0.26), knee extension (β = 0.22/β = 0.26), Timed Up-and-Go test (β = -0.16), and 5-m walking time test (β = -0.15).

CONCLUSION

In female patients with hip osteoarthritis, greater physical activity was associated with greater lower extremity muscle strength and walking ability.

Arthritis Foundation/HSS Workshop on Hip Osteoarthritis, Part 4: Nonoperative Options, Machine Learning in Predicting Total Hip Arthroplasty, Robotics, and Phenotyping to Guide Precision Rehabilitation

Far more publications are available for osteoarthritis of the knee than of the hip. Recognizing this research gap, the Arthritis Foundation (AF), in partnership with the Hospital for Special Surgery (HSS), convened an in-person meeting of thought leaders to review the state of the science of and clinical approaches to hip osteoarthritis. This article summarizes the recommendations gleaned from presentations given in the "late-stage osteoarthritis" session of the 2023 Hip Osteoarthritis Clinical Studies Conference, which took place on February 17 and 18, 2023, in New York City. It covers conservative treatment, decision-making in end-stage hip osteoarthritis, advancements in robotics, and the role of phenotyping in precision rehabilitation post-total hip arthroplasty (THA).

Exploring appropriateness criteria for informing the total knee arthroplasty decision-making process: An interpretive descriptive study

RATIONAL

The Hawker appropriateness criteria for total knee arthroplasty (TKA) are: osteoarthritis symptoms impacting quality of life, evidence of osteoarthritis, trial of conservative treatments, patient's realistic expectations, patient/surgeon agree benefits outweigh risks, and readiness for surgery. Little is known about the barriers and facilitators of using the Hawker et al. appropriateness criteria for TKA in clinical practice.

AIMS AND OBJECTIVES

Explore the barriers and facilitators to using appropriateness criteria for TKA in making decisions for adults with knee osteoarthritis.

METHODS

Interpretive descriptive qualitative study at an academic hospital. Purposive sampling aimed to recruit: (1) healthcare team members at all levels influencing care delivery, and (2) adults with TKA assessed at the hospital clinic. Semi-structured interviews asked about the barriers/facilitators to using the Hawker appropriateness criteria. Data analysis consisted of inductive thematic analysis with themes mapped to the Consolidated Framework for Implementation Research domains.

RESULTS

Nine healthcare professionals and 14 adults with TKA participated and identified common barriers to using the Hawker appropriateness criteria: (a) intervention characteristics domain: difficulty to assess criteria, patients expecting healthcare professionals to decide, limited accessibility to conservative treatments; (b) individuals characteristics domain: no need to change current TKA process, clinical judgement limited to OA severity/age, implicit assessment of subjective criteria; (c) inner setting domain: TKA information received after decision made; and (d) outer setting domain: no timely access to TKA. A facilitator of use was evidence/buy-in fosters programme changes.

CONCLUSION

Barriers to using the criteria relevant to clinical practice and the healthcare system were identified while only one facilitator was revealed. Interventions tailored to these barriers are needed to support the use of the Hawker appropriateness criteria in TKA decision-making.

Effects of closed and open kinetic chain exercises on pain, muscle strength, function, and quality of life in patients with knee osteoarthritis

OBJECTIVE

Therapeutic exercises are well documented for the treatment of osteoarthritis; there is less evidence on what the effect of closed kinetic chain exercises is for knee osteoarthritis. The aim of this study was to investigate the effects of open kinetic chain exercises and closed kinetic chain exercises on pain, muscle strength, functional status, and quality of life in patients with knee osteoarthritis.

METHODS

The study included a total of 60 patients with primary unilateral knee osteoarthritis grade I and II. The patients were categorized into three groups as open kinetic chain exercises (n=20), closed kinetic chain exercises (n=20), and control group (n=20). The outcome measures, including pain, isokinetic muscle strength, functional status, and quality of life, were collected at baseline and at the end of 6 and 12 weeks.

RESULTS

Closed kinetic chain exercises and open kinetic chain exercises had significant improvement in pain, muscle strength, WOMAC, and SF-36 scores after the treatment and at their 6th and 12th week follow-ups compared to their baseline values and compared to the control group (p<0.05).

CONCLUSION

The changes in all outcome measures were similar between closed kinetic chain exercises and open kinetic chain exercises (p>0.05). Closed kinetic chain exercises and open kinetic chain exercises were similar for knee osteoarthritis grade I and II. Closed kinetic chain exercises could be safely added to the exercise programs of patients with low-grade knee osteoarthritis.

Hip Osteoarthritis and the Risk of Lacunar Stroke: A Two-Sample Mendelian Randomization Study

Whether hip osteoarthritis (OA) could increase the risk of lacunar stroke (LS) is not well understood. This two-sample Mendelian randomization (MR) study aimed to investigate in depth the effect of genetically predicted hip OA on LS risk. Hip OA-related instrumental variables (IVs) were selected from a genome-wide association study (GWAS) of 393,873 individuals. The summary data of LS were obtained from a GWAS meta-analysis, including 16,030 cases and 248,929 controls. We used the inverse-variance weighted (IVW) as the primary MR analysis method. Moreover, the weighted-median, MR-Egger regression, and the MR pleiotropy residual sum and outlier (MR-PRESSO) test were supplementary methods. The sensitivity analysis was performed using the leave-one-out test. We identified the positive causal relationship between hip OA and the risk of LS (odds ratio [OR] = 1.20, 95% confidence interval [CI]: 1.07, 1.36; p = 0.002 using the IVW method). The weighted median method provided similar results. There was no evidence of directed pleiotropy, and sensitivity analysis results were stable, suggesting the robustness of our study. This study showed a causal effect of hip OA on the risk of LS, and more efforts should be made to explore the potential mechanisms in the future.

Clinical outcomes one year after a digital musculoskeletal (MSK) program: an observational, longitudinal study with nonparticipant comparison group

Background

The evidence base for the impact of digital health on musculoskeletal (MSK) outcomes is growing, but it is unclear how much digital MSK programs address pain and function in the intermediate and long term.

Methods

This observational study of digital MSK program participants versus nonparticipants (n = 2570) examined pain, function, depression, and anxiety at 3, 6, and 12 months, and health care use at 12 months. The intervention group engaged in a digital MSK program that included exercise, education, and coaching for at least 3 months. The nonparticipant group registered, but never started the program. We collected data in app or by emailed survey at 3, 6, and 12 months after registering for the program. We conducted descriptive analyses and unadjusted and adjusted regression modeling.

Results

The odds ratio of achieving a minimally clinically important difference (MCID) in pain improvement for the intervention versus the nonparticipant group was 1.97 (95% CI: 1.28, 3.02; p = .002) at 3 months, 1.44 (95% CI: 0.91, 2.25; p = .11) at 6 months, and 2.06 (95% CI: 1.38, 3.08; p = .004) at 12 months in adjusted models. The odds ratio of achieving a MCID in functional improvement for the intervention versus the nonparticipant group was 1.56 (95% CI: 1.03, 2.38; p = .01) at 3 months, 1.55 (95% CI: 1.02, 2.37; p = .04) at 6 months, and 1.35 (95% CI: 0.89, 2.06, p = 0.16) at 12 months in adjusted models. For those with moderate to severe depression or anxiety at baseline, we observed statistically significant lower odds of moderate to severe depression or anxiety at 3 months, 6 months, and 12 months for the intervention versus the nonparticipant group in adjusted models (p < .05). At 12 months, the percentage with invasive, imaging, and conservative services was higher for the nonparticipant versus intervention group by 5.7, 8.1, and 16.7 percentage points, respectively (p < 0.05).

Conclusions

A digital MSK program may offer participants sustained improvement in pain, depression, and anxiety with concomitant decreases in health care use.

An up to date on clinical prospects and management of osteoarthritis

The rising prevalence of osteoarthritis (OA) in the general population has necessitated the development of novel treatment options. It is critical to recognize the joint as a separate entity participating in degenerative processes, as well as the multifaceted nature of OA. OA is incurable because there is currently no medication that can stop or reverse cartilage or bone loss. As this point of view has attracted attention, more research is being directed toward determining how the various joint components are impacted and how they contribute to OA pathogenesis. Over the next few years, several prospective therapies focusing on inflammation, cartilage metabolism, subchondral bone remodelling, cellular senescence, and the peripheral nociceptive pathway are predicted to transform the OA therapy landscape. Stem cell therapies and the use of various biomaterials to target articular cartilage (AC) and osteochondral tissues are now being investigated in considerable detail. Currently, laboratory-made cartilage tissues are on the verge of being used in clinical settings. This review focuses on the update of clinical prospects and management of osteoarthritis, as well as future possibilities for the treatment of OA.

The Role of Chiropractic Care in Providing Health Promotion and Clinical Preventive Services for Adult Patients with Musculoskeletal Pain: A Clinical Practice Guideline

Objective: To develop evidence-based recommendations on best practices for delivery of clinical preventive services by chiropractors and to offer practical resources to empower provider applications in practice. Design: Clinical practice guideline based on evidence-based recommendations of a panel of practitioners and experts on clinical preventive services. Methods: Synthesizing the results of a literature search for relevant clinical practice guidelines and systematic reviews, a multidisciplinary steering committee with training and experience in health promotion, clinical prevention, and/or evidence-based chiropractic practice drafted a set of recommendations. A Delphi panel of experienced practitioners and faculty, primarily but not exclusively chiropractors, rated the recommendations by using the formal consensus methodology established by the RAND Corporation/University of California. Results: The Delphi consensus process was conducted during January-February 2021. The 65-member Delphi panel reached a high level of consensus on appropriate application of clinical preventive services for screening and health promotion counseling within the chiropractic scope of practice. Interprofessional collaboration for the successful delivery of clinical preventive services was emphasized. Recommendations were made on primary, secondary, tertiary, and quaternary prevention of musculoskeletal pain. Conclusions: Application of this guideline in chiropractic practice may facilitate consistent and appropriate use of screening and preventive services and foster interprofessional collaboration to promote clinical preventive services and contribute to improved public health.

Efficacy and safety of a supplement combination on hand pain among people with symptomatic hand osteoarthritis an internet-based, randomised clinical trial the RADIANT study

OBJECTIVE

The RADIANT study aimed to investigate the efficacy and safety of a complementary medicine supplement combination in people with hand osteoarthritis (HOA).

METHOD

This was an internet-based, double-blind, randomised, placebo-controlled trial. Participants aged over 40 years with symptomatic HOA with radiographic confirmation (Kellgren Lawrence grade ≥ 2) throughout Australia were recruited and randomly assigned (1:1) to receive either a supplement combination composed of Boswellia serrata extract 250 mg/day, pine bark extract 100 mg/day, methylsulfonylmethane 1,500 mg/day and curcumin 168 mg/day or placebo for 12 weeks. The primary outcome was change in hand pain assessed using a visual analogue scale (VAS 0-100) from baseline to week 12. A range of secondary outcomes and additional measures were recorded. Adverse events were monitored weekly.

RESULTS

One hundred and six participants were included with mean age 65.6 years and 81% were women. 45% of the participants were graded as KLG 4, 40% KLG three and 39 (37%) had erosive OA. There was no significant difference in pain VAS reduction between groups. The adjusted between group difference in means (95%CI) was 5.34 (-2.39 to 13.07). Five participants (10%) in the supplement combination group discontinued study treatment due to AE vs four participants (7%) in the placebo group.

CONCLUSION

There were no significant differences in symptomatic relief between the two groups over 12 weeks. These findings do not support the use of the supplement combination for treating hand pain in people with HOA.

Effects of various types of ultrasound therapy in hip osteoarthritis - a double-blind, randomized, controlled, follow-up study

Purpose: To compare the effects of various types of ultrasound therapy (UST) on pain, function, and quality of life in patients with hip osteoarthritis.Methods: Seventy-one patients receiving conventional physiotherapy (exercise, massage, and balneotherapy), were randomly allocated into four treatment groups: (1) continuous UST, (2) pulsed UST, (3) UST combined with transcutaneous electrical nerve stimulation (TENS), (4) placebo UST. We evaluated the hip pain (Visual Analog Scale), medication use, functional impairment (Western Ontario and McMaster Universities Arthritis Index; 6-minute walking test) and quality of life (SF-36) before, right after the treatments, and at 3 months follow-up.Results: Resting pain improved significantly in all treatment groups at the follow-up visit compared to baseline (p (group1-4) ≤0.002). The proportion of patients achieving Minimal Clinically Important Improvement (MCII) in function at month 3 was the highest in group 3 (73%). The 6-minute walking test significantly improved in each group during the follow-up period (p (group1-4) ≤ 0.025). Pain (p (group1-4) ≤ 0.014) and general health domains of the SF-36 showed the greatest improvement (p (group 2-4) ≤ 0.018).Conclusions: There was no difference among the effects of various types of UST on pain, function, and quality of life in the treatment of hip osteoarthritis. Additional ultrasound treatment is not likely to increase the effect of the conventional therapy on pain and function in hip osteoarthritis.

Oxygen-Ozone Therapy in the Rehabilitation Field: State of the Art on Mechanisms of Action, Safety and Effectiveness in Patients with Musculoskeletal Disorders

In recent years, the interest in oxygen–ozone (O₂O₃) therapy application has considerably increased in the field of rehabilitation. Despite its widespread use in common clinical practice, the biochemical effects of O₂O₃ are still far from being understood, although its chemical properties seem to play a pivotal role in exerting its positive effects on different pathological conditions. Indeed, the effectiveness of O₂O₃ therapy might be partly due to the moderate oxidative stress produced by O₃ interactions with biological components. O₂O₃ therapy is widely used as an adjuvant therapeutic option in several pathological conditions characterized by chronic inflammatory processes and immune over-activation, and most musculoskeletal disorders share these pathophysiological processes. The present comprehensive review depicts the state-of-the-art on the mechanisms of action, safety and effectiveness of O₂O₃ therapy in the complex scenario of the management of musculoskeletal disorders. Taken together, our findings suggest that O₂O₃ therapy seems to reduce pain and improve functioning in patients affected by low back pain and knee osteoarthritis, as reported by several studies in the literature. However, to date, further studies are warranted to clearly investigate the therapeutic effects of this promising therapy on other musculoskeletal disorders in the field of rehabilitation.

Best Practices for Chiropractic Management of Patients with Chronic Musculoskeletal Pain: A Clinical Practice Guideline

Objective: To develop an evidence-based clinical practice guideline (CPG) through a broad-based consensus process on best practices for chiropractic management of patients with chronic musculoskeletal (MSK) pain. Design: CPG based on evidence-based recommendations of a panel of experts in chronic MSK pain management. Methods: Using systematic reviews identified in an initial literature search, a steering committee of experts in research and management of patients with chronic MSK pain drafted a set of recommendations. Additional supportive literature was identified to supplement gaps in the evidence base. A multidisciplinary panel of experienced practitioners and educators rated the recommendations through a formal Delphi consensus process using the RAND Corporation/University of California, Los Angeles, methodology. Results: The Delphi process was conducted January-February 2020. The 62-member Delphi panel reached consensus on chiropractic management of five common chronic MSK pain conditions: low-back pain (LBP), neck pain, tension headache, osteoarthritis (knee and hip), and fibromyalgia. Recommendations were made for nonpharmacological treatments, including acupuncture, spinal manipulation/mobilization, and other manual therapy; modalities such as low-level laser and interferential current; exercise, including yoga; mind-body interventions, including mindfulness meditation and cognitive behavior therapy; and lifestyle modifications such as diet and tobacco cessation. Recommendations covered many aspects of the clinical encounter, from informed consent through diagnosis, assessment, treatment planning and implementation, and concurrent management and referral. Appropriate referral and comanagement were emphasized. Conclusions: These evidence-based recommendations for a variety of conservative treatment approaches to the management of common chronic MSK pain conditions may advance consistency of care, foster collaboration between provider groups, and thereby improve patient outcomes.

Effects of foam rolling on hip pain in patients with hip osteoarthritis: a retrospective propensity-matched cohort study

BACKGROUND

Foam rolling is a self-applied massage using a foam roller that has gained popularity for treatment of muscle soreness. However, its efficacy for improving hip pain in patients with hip osteoarthritis remains unclear.

OBJECTIVE

To investigate the effects of foam rolling on hip pain in patients with hip osteoarthritis.

METHODS

In this retrospective propensity-matched cohort study, medical records of outpatients between January 2017 and March 2019 were reviewed. Of these, 115 patients with hip osteoarthritis were divided into foam rolling or non-foam rolling groups based on home exercises. Both groups were propensity-score matched (1:1) for age, sex, body mass index, Kellgren and Lawrence grade, and visual analog scale (VAS) of hip pain at baseline. The primary outcome was the hip pain-VAS. Effects of interventions on the hip pain-VAS were examined using a split-plot design variance analysis.

RESULTS

After matching, both groups comprised 37 patients each. No significant differences were observed in baseline characteristics and outcome measurements between the matched groups. A statistically significant interaction was seen between the effects of time and group for hip pain-VAS (F [1, 72] = 31.874, interaction: P < .001, η² = 0.307). Hip pain-VAS was improved more effectively in the foam rolling group than those in the non-foam rolling group (P < .001). Thirty-four (92%) patients in the foam rolling group, compared to 15 (41%) in the non-foam rolling group, showed a ≥ 32% (minimal clinically important difference) improvement in hip pain-VAS.

CONCLUSION

These results suggested that foam rolling was an effective intervention for improving hip pain in patients with hip osteoarthritis.

Minimally Invasive Therapies for Osteoarthritic Hip Pain: a Comprehensive Review

PURPOSE OF REVIEW

Osteoarthritis (OA) is a highly prevalent cause of chronic hip pain, affecting 27% of adults aged over 45 years and 42% of adults aged over 75 years. Though OA has traditionally been described as a disorder of "wear-and-tear," recent studies have expanded on this understanding to include a possible inflammatory etiology as well, damage to articular cartilage produces debris in the joint that is phagocytosed by synovial cells which leads to inflammation.

RECENT FINDINGS

Patients with OA of the hip frequently have decreased quality of life due to pain and limited mobility though additional comorbidities of diabetes, cardiovascular disease, poor sleep quality, and obesity have been correlated. Initial treatment with conservative medical management can provide effective symptomatic relief. Physical therapy and exercise are important components of a multimodal approach to osteoarthritic hip pain. Patients with persistent pain may benefit from minimally invasive therapeutic approaches prior to consideration of undergoing total hip arthroplasty. The objective of this review is to provide an update of current minimally invasive therapies for the treatment of pain stemming from hip osteoarthritis; these include intra-articular injection of medication, regenerative therapies, and radiofrequency ablation.

Exercise and Chronic Pain

In this chapter, we describe the impact and etiology of chronic pain, the associated changes in the nervous system, and the mechanisms by which exercise may be able to affect and reverse these changes. Evidence for efficacy of exercise in different conditions associated with chronic pain is presented, with focus on chronic low back pain, fibromyalgia, osteoarthritis, rheumatoid arthritis, and migraines. While the efficacy of exercise and level of evidence supporting it vary in different diseases, exercise has direct and indirect benefits for most patients suffering from chronic pain. Effective exercise regimens include education and cognitive restructuring to promote behavioral activation and reconceptualization of what pain means, with the goal of gradually reversing the vicious cycle of pain, inertia, sedentary behavior, and worsening disability. Long-term, consistent, individualized exercise-based treatment approaches are most likely to result in improvements in pain and function.

Exercise and Osteoarthritis

Osteoarthritis (OA) is a degenerative disease of the articular cartilage with subchondral bone lesions. Osteoarthritis etiologies are mainly related to age, obesity, strain, trauma, joint congenital anomalies, joint deformities, and other factors. Osteoarthritis seriously affects the quality of life; however, there is no effective way to cure osteoarthritis. Aerobic exercise refers to a dynamic rhythmic exercise involving the large muscle groups of the body with aerobic metabolism. More and more evidence shows that exercise has become a useful tool for the treatment of osteoarthritis. This chapter will discuss the role of exercise in the prevention and treatment of osteoarthritis.

Photobiomodulation via a cluster device associated with a physical exercise program in the level of pain and muscle strength in middle-aged and older women with knee osteoarthritis: a randomized placebo-controlled trial

Osteoarthritis (OA) is a chronic joint disease that leads to pain and functional incapacity. The aim of the study is to investigate the effects of the incorporation of photobiomodulation (PBM) (via cluster) into a physical exercise program on the level of pain, lower limb muscle strength, and physical capacity, in patients with knee OA. Sixty-two female volunteers with a diagnosis of knee OA were distributed in 4 groups: exercise associated with placebo PBM group, exercise associated with active PBM group, active PBM group, and placebo PBM group. Sixteen sessions of lower limb strength exercises and PBM via cluster (808 nm, 100 mW, 7 points each side, 56 J total) were performed. The level of pain, physical capacity, and lower limb muscle strength were evaluated with the use of the numeric pain rating scale (NPRS), 6-min walking test (6-MWT) and timed up and go (TUG), and maximal voluntary isometric torque (MVIT) before and after the interventions. Both groups presented a significant decrease in the level of pain when compared with the placebo-treated women. Furthermore, the 6-MWT showed that the trained groups (with or without PBM) demonstrated higher values in the distance walked comparing pre and post-treatment values. The same behavior was found for the MVIT load before and after intervention. TUG was higher for all the treated with exercise groups comparing the pre and post-treatment values. Physical exercise and PBM showed analgesic effects. However, PBM did not have any extra effect along with the effects of exercise in improving the distance walked, the TUG, and the muscle strength.Trial registration: RBR-7t6nzr.
