Exercise, manual therapy, and use of booster sessions in physical therapy for knee osteoarthritis: a multi-center, factorial randomized clinical trial

Tuina on knee pain and functional decline of lower limbs for patients with mild-to-moderate knee osteoarthritis in Shanghai: protocol for a multicentre, assessor-blinded, randomised controlled trial

INTRODUCTION

Knee osteoarthritis (KOA) is one of the most common osteoarthritis, imposing substantial economic and medical burdens on both individuals and society. In China, Tuina has been selected as a complementary and alternative therapy to relieve knee pain and dysfunction symptoms. However, the current evidence is insufficient to support the efficacy of Tuina therapy in addressing knee pain and improving physical function. The trial aims to compare the effectiveness of Tuina with celecoxib, which is considered as the standard treatment, and to assess its potential as an alternative therapy through changes in outcome measures.

METHODS AND ANALYSIS

A total of 360 KOA patients aged between 40 and 70 years and classified as Kellgren and Lawrence grades I-II will be recruited from eight subcentral hospitals. The participants will be randomly assigned to either the treatment group (Tuina, Biw) or the control group (celecoxib, Qd), with both groups undergoing a 4-week intervention phase followed by an 8-week follow-up phase. The primary outcome is the change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale at week 4 compared with baseline. Secondary outcomes including WOMAC stiffness and function subscales, WOMAC total score, 36-item Short-Form Health Survey, Timed Up and Go test, Short Physical Performance Battery, gait analysis parameters and pain medication records will be assessed at weeks 4, 8 and 12. Any adverse events that occur during the trial will be promptly recorded.

ETHICS AND DISSEMINATION

This study has been approved by the Ethics Committee of Shanghai Municipal Hospital of Traditional Chinese Medicine (2023SHL-KY-16-01, 2023SHL-KY-16-02). Written informed consent will be obtained from all participants. Study results will be disseminated through peer-reviewed journals and conference presentations.

Booster visits in the management of the acute musculoskeletal injuries: Transforming care to improve outcomes-A perspective review

The current healthcare delivery system for patients with acute musculoskeletal injury is failing. Current rehabilitation management of acute musculoskeletal injury typically includes physical therapy, focused on management of impairments, with an eventual transition to functional activities and release to prior level of function. At that point, formal physical therapy is often discontinued, despite the knowledge that a high percentage of patients fail to maintain preinjury level of activity and often reduce participation in regular physical activity. Further, for those who attempt to return to prior levels of pivoting and cutting activities, there is a high second injury rate. The long-term human experience is compromised by the current model of care which terminates at the point of transition to activity. This model of care fails to meet the continued needs of these patients and may result in long term deficits and potential disability. Extended care models include intermittent follow up visits after discharge from an acute episode of care and have been efficacious and cost effective in some patient populations with musculoskeletal conditions. Specifically, a type of extended care model, labeled "booster sessions," represents an opportunity to provide structured, intermittent care to assist in a smooth transition back to function, following an acute episode of care and promote a healthier life outcome. This perspective review will discuss the opportunity to transform acute musculoskeletal care to booster visit care model in an attempt to develop a more efficacious and cost-effective system of care which could be generalizable to all musculoskeletal conditions.

Budget impact of the Walk With Ease program for knee osteoarthritis

Objective

Walk With Ease (WWE) is an effective low-cost walking program. We estimated the budget impact of implementing WWE in persons with knee osteoarthritis (OA) as a measure of affordability that can inform payers' funding decisions.

Methods

We estimated changes in two-year healthcare costs with and without WWE. We used the Osteoarthritis Policy (OAPol) Model to estimate per-person medical expenditures. We estimated total and per-member-per-month (PMPM) costs of funding WWE for a hypothetical insurance plan with 75,000 members under two conditions: 1) all individuals aged 45+ with knee OA eligible for WWE, and 2) inactive and insufficiently active individuals aged 45+ with knee OA eligible. In sensitivity analyses, we varied WWE cost and efficacy and considered productivity costs.

Results

With eligibility unrestricted by activity level, implementing WWE results in an additional $1,002,408 to the insurance plan over two years ($0.56 PMPM). With eligibility restricted to inactive and insufficiently active individuals, funding WWE results in an additional $571,931 over two years ($0.32 PMPM). In sensitivity analyses, when per-person costs of $10 to $1000 were added with 10-50% decreases in failure rate (enhanced sustainability of WWE benefits), two-year budget impact varied from $242,684 to $6,985,674 with unrestricted eligibility and from -$43,194 (cost-saving) to $4,484,122 with restricted eligibility.

Conclusion

Along with the cost-effectiveness of WWE at widely accepted willingness-to-pay thresholds, these results can inform payers in deciding to fund WWE. In the absence of accepted thresholds to define affordability, these results can assist in comparing the affordability of WWE with other behavioral interventions.

The effects of manual therapy in pain and safety of patients with knee osteoarthritis: a systematic review and meta-analysis

BACKGROUND

Manual therapy (MT) is frequently used in combination with management of osteoarthritis of the knee, but there is no consensus on the exact efficacy of this treatment strategy. The purpose of this systematic review and meta-analysis was to evaluate the pain relief and safety of MT for treatment of knee osteoarthritis (KOA).

METHODS

Randomized controlled trials evaluating MT in patients with KOA in major English and Chinese journals were searched in the following databases: Wanfang, China Science and Technology Journal Database (VIP database), China National Knowledge Infrastructure (CNKI), PubMed, Embase, Web of Science, and the Cochrane Library databases through June 2023. The methodological quality and quality of evidence of the included studies were assessed using Cochrane's risk-of-bias 2 (ROB 2) tool and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool. Data analysis was performed using Stata version 15.0 software. After use of Galbraith plots to exclude studies that could lead to heterogeneity, random effects models were used to analyze the remaining data and test the consistency of the findings. We used meta-regression to assess the effect of treatment period, patient age, and sex ratio on outcomes. Funnel plots and Egger's test were used to evaluate publication bias. Sensitivity analyses were used to determine the reliability of the results.

RESULTS

A total of 25 studies, with 2376 participants, were included in this review. The overall methodological quality of the included studies was limited. Our findings suggest that MT has a positive impact on pain relief outcomes in KOA patients. The meta-analysis showed that MT was superior to usual care (SMD = 2.04, 95% CI 0.94, 3.14, I 2 = 96.3%; low evidence quality) and exercise (SMD = 1.56, 95% CI 0.41, 2.71, I 2 = 96.3%; low evidence quality) for reducing pain. In terms of improvement in visual analogue scale (VAS) scores, MT treatment beyond 4 weeks (SMD = 1.56, 95% CI 0.41, 2.71, I 2 = 96.3%) may be superior to treatments less than or equal to 4 weeks (SMD = 1.24, 95% CI 0.56, 1.95, I 2 = 94.7%). No serious adverse events associated with MT were reported.

CONCLUSIONS

MT may be effective at reducing pain in patients with KOA and may be more effective after a 4-week treatment period. Compared with usual care and exercise therapy, MT may be superior at reducing KOA pain in the short term (9 weeks), but its long-term efficacy requires careful consideration of evidence-based outcomes. MT appears to be safe for KOA patients, though clinicians should inform patients of the potential risk of MT-related adverse events.

Adverse Events Reported in Trials Assessing Manual Therapy to the Extremities: A Systematic Review

Objective: This review aimed to describe the quality and comprehensiveness of adverse event (AE) reporting in clinical trials incorporating manual therapy (MT) as an intervention for extremity conditions using the Consolidated Standards of Reporting Trials (CONSORT)-Harms extension as the benchmark. The secondary aim was to determine whether the quality of AE reporting improved after the availability of the CONSORT reporting checklist. Design: Systematic review. Methods: A literature search was conducted using multiple databases to identify trials where MT was used to treat extremity conditions. Studies that reported AEs were identified and evaluated using the CONSORT-Harms extension. The frequency of trials reporting study AEs before and after the publication of the updated 2010 CONSORT statement was calculated, along with the categorization of how study AEs were reported. Results: Of the 55,539 studies initially identified, 220 trials met all inclusion criteria. Eighty trials (36.4%) reported AE occurrence. None of the studies that reported AEs adhered to all 10 criteria proposed by the 2010 CONSORT-Harms extension. The most commonly reported criterion was number four, which clarified how AE-related information was collected (30% of trials). The least reported criterion was number six, which describes the participant withdrawals for each arm due to AEs and the experience with the allocated treatment (1.3% of trials). The nomenclature used to describe AEs varied substantially. Fifty-nine of 76 trials (33.3%) were published after the updated CONSORT Harms-checklist was available, compared to 21 of 44 trials (46.7%) published before it was available. Conclusion: Reporting of AEs in trials investigating MT for extremity conditions is poor. Every included trial lacked adherence to all 10 criteria proposed by the CONSORT-Harms Extension. The quality and comprehensiveness of AE reporting did not improve after the most recent CONSORT update recommending AE reporting. Clinicians must obtain informed consent before performing any intervention, including MT, which requires disclosing potential risks, which could be better known with improved tracking, analyzing, and reporting of AEs. The authors recommend improved adherence to best practices for adequately tracking and reporting AEs in future MT trials.

Pragmatism in manual therapy trials for knee osteoarthritis: a systematic review

Introduction

Manual therapy is an often-utilized intervention for the management of knee osteoarthritis (OA). The interpretation of results presented by these trials can be affected by how well the study designs align applicability to real-world clinical settings.

Aim

To examine the existing body of clinical trials investigating manual therapy for knee OA to determine where they fall on the efficacy-effectiveness spectrum.

Methods

This systematic review has been guided and informed by the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Randomized controlled trials that investigated manual therapy treatments for adults with knee OA were retrieved via searches of multiple databases to identify trials published prior to April 2023. The Rating of Included Trials on the Efficacy-Effectiveness Spectrum (RITES) tool was used to objectively rate the efficacy-effectiveness nature of each trial design. The Cochrane Risk of Bias 2.0 assessment tool (RoB-2) was used to assess the risk of bias across five domains.

Results

Of the 36 trials, a higher percentage of trials had a greater emphasis on efficacy within all four domains: participant characteristics (75.0%), trial setting (77.8%), flexibility of intervention (58.3%), and clinical relevance of experimental and comparison intervention (47.2%). In addition, 13.9% of the trials had low risk of bias, 41.7% had high risk of bias, and 44.4% had some concerns regarding bias.

Conclusions

While many trials support manual therapy as effective for the management of knee OA, a greater focus on study designs with an emphasis on effectiveness would improve the applicability and generalizability of future trials.

Walk with ease for knee osteoarthritis: A cost-effectiveness analysis

Objective

The Walk With Ease (WWE) program was developed by the Arthritis Foundation to help people with arthritis learn to exercise safely and improve arthritis symptoms. We sought to establish the value of the WWE program.

Methods

We used the Osteoarthritis Policy (OAPol) Model, a widely published and validated computer simulation of knee osteoarthritis (OA), to assess the cost-effectiveness of WWE in knee OA. We derived model inputs using data from a workplace wellness initiative in Montana that offered WWE to state employees. Our primary outcomes were quality-adjusted life years (QALYs) and costs over a 2-year period, which we used to calculate the incremental cost-effectiveness ratio (ICER). The base case analysis was restricted to subjects who were inactive or insufficiently active (<180 ​min/week of PA) at baseline. We performed scenario and probabilistic sensitivity analyses to determine the impact of uncertainty in model parameters on our results.

Results

In the base case analysis, adding WWE to usual care resulted in an ICER of $47,900/QALY. When the program was offered without preselection by baseline activity level, the ICER for WWE ​+ ​usual care was estimated at $83,400/QALY. Results of the probabilistic sensitivity analysis indicated that WWE offered to inactive or insufficiently active individuals has a 52% chance of having an ICER <$50,000/QALY.

Conclusion

The WWE program offers good value for inactive/insufficiently active individuals. Payers may consider including such a program to increase physical activity in individuals with knee OA.

Photobiomodulation does not provide incremental benefits to patients with knee osteoarthritis who receive a strengthening exercises program: a randomized controlled trial

BACKGROUND

There is lack of agreement in the literature about the effectiveness of photobiomodulation (PBM) for reducing pain-related symptoms in patients with knee osteoarthritis (OA).

OBJECTIVE

To evaluate whether PBM, when combined to exercises, provides incremental therapeutic benefits for pain, physical function, and quality of life (QoL) in patients with knee OA.

METHODS

A six-month double-blind placebo-controlled randomized trial was conducted. Patients with knee OA were randomly assigned to one of three treatment groups: Exercise, Exercise plus Active PBM, or Exercise plus Placebo PBM. Treatment was provided over an eight-week period, three times per week. The primary outcomes were pain at rest and upon movement, assessed by a visual analogue scale (VAS). WOMAC global score, QoL, and a core-set of performance-based tests were measured as secondary outcomes. All outcomes were collected at baseline, immediately after treatment, and after three- and six-month post-treatment.

RESULTS

127 participants were allocated as follows: Exercise, N = 41; Exercise plus Active PBM, N = 44; and Exercise plus Placebo PBM, N = 42. There was no between-groups difference in improvement in pain, physical function, and QoL for all follow-up times. However, all groups presented significant, clinically relevant improvements in pain, physical function, and QoL immediately and three months after treatment compared with baseline measures.

CONCLUSION

Patients with knee OA who received a strengthening exercises program did not experience incremental benefits regarding pain, physical function, or QoL when adding PBM to their therapeutic exercises.

Pain neuroscience education, blended exercises and booster sessions as an effective therapy for pain, functional and psychological factors in patients with knee osteoarthritis: a study protocol for a single-blind randomised controlled trial with 22 factorial design during 6-month follow-up

INTRODUCTION

This study aims to investigate whether a pain neuroscience education (PNE) combined with a blended exercises programme including aerobic, resistance, neuromuscular, breathing, stretching and balance exercises and diet education provides greater pain relief and improvement in functional and psychological factors than PNE and blended exercises alone and whether 'exercise booster sessions (EBS)' approach may improve outcomes and increase adherence in patients with knee osteoarthritis (KOA) (by telerehabilitation (TR)).

METHODS AND ANALYSIS

In this single-blind randomised controlled trial, 129 patients (both genders; age >40) diagnosed with KOA will be randomly assigned to one of the 22 treatment combinations as: (1) blended exercises alone (36 sessions over 12 weeks), (2) PNE alone (three sessions over 2 weeks), (3) combination of PNE with blended exercises (exercise three times a week for 12 weeks combined with three sessions of PNE) and (4) a control group. Outcome assessors will be blinded towards group allocation. The primary outcome variables are the visual analogue scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis index in knee osteoarthritis (WOMAC) score. Secondary outcomes include Pain Self-Efficacy Questionnaire (PSEQ), Depression, Anxiety and Stress Scale (DASS), Tampa Scale for Kinesiophobia (TSK), Short Falls Efficacy Scale International (FES-I), Pain Catastrophising Scale (PCS), Short Form Health Survey (SF-12) and Exercise Adherence Rating Scale (EARS), 30 s sit-to-stand test (30CST), Timed Up and Go (TUG), lower limbs' muscle strength and lower limb joints' active range of motion (AROM) will be performed at baseline, 3 and 6 months' postinterventions. The primary and secondary outcomes will assess at baseline, 3 months and 6 months postinterventions.The findings will be useful in establishing an effective treatment strategy covering multiple aspects behind KOA. The study protocol is conducted in clinical settings, thereby enhancing the possibility of future implementation of the treatments in the healthcare systems and self-care management. Results in comparison between groups will help to clarify the most effective of mixed-method TR (blended exercise, PNE, EBS with diet education) on more improvement in pain, functional and psychological factors in patients with KOA. This study will combine some of the most critical interventions, to be able to introduce a 'gold standard therapy' in the treatment of KOA.

ETHICS AND DISSEMINATION

The trial has been approved by the ethics committee for research involving human subjects of the Sport Sciences Research Institute of Iran (IR.SSRC.REC.1401.021). The study findings will be published in international peer-reviewed journals.

Surgical Versus Non-Surgical Treatments for the Knee: Which Is More Effective?

Osteoarthritis is a degenerative joint disease that is extremely prevalent in society. It affects more than 25% of Americans above the age of 18 years. According to July 2020 publication by the Centers for Disease Control (CDC), osteoarthritis affects approximately 325 million Americans. One of the organs that is most affected by osteoarthritis is the knee. Over the years, we have developed non-surgical treatments, such as physical therapy (PT) and injections, and surgical treatments, such as total knee arthroplasty (TKA) and arthroscopic lavage, for knee osteoarthritis (KOA). If a patient fails with non-surgical options, which are tried first to avoid the risks of surgery, the patient may be considered for knee surgery. This article will investigate the different non-surgical options and TKA as treatment options for KOA based on current literature. The goal of this paper is to be a comprehensive resource for physicians and patients with KOA to make an informed decision. A systematic literature search was conducted using PubMed. The search terms were based on the type of treatments for KOA. To find articles that compared TKA to non-surgical treatments, the terms included "osteoarthritis", "total knee", and "non-surgical treatments," in combination. For other non-surgical treatments such as PT, weight reduction, and injections, a combination of the treatment, "osteoarthritis", and "knee" were included in the search. For the tier 1 process, any randomized controlled trials were included. Any case reports, observational studies, and cross-sectional studies were eliminated from the search. For the tier 2 review process, any articles that did not have relevance to the topic were eliminated after reading the abstracts of the articles. After review of the literature, the data seem to suggest that TKA with 12 weeks of non-surgical treatment improved pain and functionality of the knee more than just 12 weeks of non-surgical treatment when followed up at 12 and 24 months. However, non-surgical treatment before TKA delays the need for surgery. Supervised PT, either in a group or individual format, has been shown to delay TKA in 95% patients in the group that received PT at the end of one year. In addition, weight reduction has been shown as an effective strategy to improve pain and functionality in KOA patients, which decreases the urgency for surgery. Furthermore, platelet-rich plasma (PRP) injections have been shown to have long-term symptomatic relief for KOA compared to hyaluronic acid (HA) and corticosteroid injections. However, HA and corticosteroid injections are beneficial in treating KOA more than receiving no treatment. Physicians often have difficulty deciding whether to pursue conservative or surgical treatment for patients with KOA. The non-surgical treatments explored in this review - PT, injections, and weight reduction - can provide symptomatic relief and, in some cases, delay the need for surgical intervention. However, based on some randomized clinical trials mentioned in the article, patients receiving TKA have more relief, better quality of life, and improved functionality compared to non-surgical therapy. However, a critical review of this important field of debate shows that there are limited randomized controlled studies comparing the effectiveness of TKA and non-surgical treatments for KOA. We believe that this controversial topic needs further clinical investigation.

Adjunctive therapies in addition to land-based exercise therapy for osteoarthritis of the hip or knee

BACKGROUND

Land-based exercise therapy is recommended in clinical guidelines for hip or knee osteoarthritis. Adjunctive non-pharmacological therapies are commonly used alongside exercise in hip or knee osteoarthritis management, but cumulative evidence for adjuncts to land-based exercise therapy is lacking.

OBJECTIVES

To evaluate the benefits and harms of adjunctive therapies used in addition to land-based exercise therapy compared with placebo adjunctive therapy added to land-based exercise therapy, or land-based exercise therapy only for people with hip or knee osteoarthritis.

SEARCH METHODS

We searched CENTRAL, MEDLINE, PsycINFO, EMBASE, CINAHL, Physiotherapy Evidence Database (PEDro) and clinical trials registries up to 10 June 2021.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) or quasi-RCTs of people with hip or knee osteoarthritis comparing adjunctive therapies alongside land-based exercise therapy (experimental group) versus placebo adjunctive therapies alongside land-based exercise therapy, or land-based exercise therapy (control groups). Exercise had to be identical in both groups. Major outcomes were pain, physical function, participant-reported global assessment, quality of life (QOL), radiographic joint structural changes, adverse events and withdrawals due to adverse events. We evaluated short-term (6 months), medium-term (6 to 12 months) and long-term (12 months onwards) effects.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed study eligibility, extracted data, and assessed risk of bias and certainty of evidence for major outcomes using GRADE.

MAIN RESULTS

We included 62 trials (60 RCTs and 2 quasi-RCTs) totalling 6508 participants. One trial included people with hip osteoarthritis, one hip or knee osteoarthritis and 59 included people with knee osteoarthritis only. Thirty-six trials evaluated electrophysical agents, seven manual therapies, four acupuncture or dry needling, or taping, three psychological therapies, dietary interventions or whole body vibration, two spa or peloid therapy and one foot insoles. Twenty-one trials included a placebo adjunctive therapy. We presented the effects stratified by different adjunctive therapies along with the overall results. We judged most trials to be at risk of bias, including 55% at risk of selection bias, 74% at risk of performance bias and 79% at risk of detection bias. Adverse events were reported in eight (13%) trials. Comparing adjunctive therapies plus land-based exercise therapy against placebo therapies plus exercise up to six months (short-term), we found low-certainty evidence for reduced pain and function, which did not meet our prespecified threshold for a clinically important difference. Mean pain intensity was 5.4 in the placebo group on a 0 to 10 numerical pain rating scale (NPRS) (lower scores represent less pain), and 0.77 points lower (0.48 points better to 1.16 points better) in the adjunctive therapy and exercise therapy group; relative improvement 10% (6% to 15% better) (22 studies; 1428 participants). Mean physical function on the Western Ontario and McMaster (WOMAC) 0 to 68 physical function (lower scores represent better function) subscale was 32.5 points in the placebo group and reduced by 5.03 points (2.57 points better to 7.61 points better) in the adjunctive therapy and exercise therapy group; relative improvement 12% (6% better to 18% better) (20 studies; 1361 participants). Moderate-certainty evidence indicates that adjunctive therapies did not improve QOL (SF-36 0 to 100 scale, higher scores represent better QOL). Placebo group mean QOL was 81.8 points, and 0.75 points worse (4.80 points worse to 3.39 points better) in the placebo adjunctive therapy group; relative improvement 1% (7% worse to 5% better) (two trials; 82 participants). Low-certainty evidence (two trials; 340 participants) indicates adjunctive therapies plus exercise may not increase adverse events compared to placebo therapies plus exercise (31% versus 13%; risk ratio (RR) 2.41, 95% confidence interval (CI) 0.27 to 21.90). Participant-reported global assessment was not measured in any studies. Compared with land-based exercise therapy, low-certainty evidence indicates that adjunctive electrophysical agents alongside exercise produced short-term (0 to 6 months) pain reduction of 0.41 points (0.17 points better to 0.63 points better); mean pain in the exercise-only group was 3.8 points and 0.41 points better in the adjunctive therapy plus exercise group (0 to 10 NPRS); relative improvement 7% (3% better to 11% better) (45 studies; 3322 participants). Mean physical function (0 to 68 WOMAC subscale) was 18.2 points in the exercise group and 2.83 points better (1.62 points better to 4.04 points better) in the adjunctive therapy plus exercise group; relative improvement 9% (5% better to 13% better) (45 studies; 3323 participants). These results are not clinically important. Mean QOL in the exercise group was 56.1 points and 1.04 points worse in the adjunctive therapies plus exercise therapy group (1.04 points worse to 3.12 points better); relative improvement 2% (2% worse to 5% better) (11 studies; 1483 participants), indicating no benefit (low-certainty evidence). Moderate-certainty evidence indicates that adjunctive therapies plus exercise probably result in a slight increase in participant-reported global assessment (short-term), with success reported by 45% in the exercise therapy group and 17% more individuals receiving adjunctive therapies and exercise (RR 1.37, 95% CI 1.15 to 1.62) (5 studies; 840 participants). One study (156 participants) showed little difference in radiographic joint structural changes (0.25 mm less, 95% CI -0.32 to -0.18 mm); 12% relative improvement (6% better to 18% better). Low-certainty evidence (8 trials; 1542 participants) indicates that adjunctive therapies plus exercise may not increase adverse events compared with exercise only (8.6% versus 6.5%; RR 1.33, 95% CI 0.78 to 2.27).

AUTHORS' CONCLUSIONS

Moderate- to low-certainty evidence showed no difference in pain, physical function or QOL between adjunctive therapies and placebo adjunctive therapies, or in pain, physical function, QOL or joint structural changes, compared to exercise only. Participant-reported global assessment was not reported for placebo comparisons, but there is probably a slight clinical benefit for adjunctive therapies plus exercise compared with exercise, based on a small number of studies. This may be explained by additional constructs captured in global measures compared with specific measures. Although results indicate no increased adverse events for adjunctive therapies used with exercise, these were poorly reported. Most studies evaluated short-term effects, with limited medium- or long-term evaluation. Due to a preponderance of knee osteoarthritis trials, we urge caution in extrapolating the findings to populations with hip osteoarthritis.

The Benefits of Adding Manual Therapy to Exercise Therapy for Improving Pain and Function in Patients With Knee or Hip Osteoarthritis: A Systematic Review With Meta-analysis

OBJECTIVE: To evaluate if there was an additional benefit of combining manual therapy (MT) and exercise therapy over exercise therapy alone on pain and function in patients with hip or knee osteoarthritis. DESIGN: Intervention systematic review LITERATURE SEARCH: We (1) searched 4 databases from inception to June 20, 2021; (2) hand searched a reference list of included trials and relevant systematic reviews; and (3) contacted 2 researchers in the field. STUDY SELECTION CRITERIA: We included randomized controlled trials that compared MT and exercise therapy to similar exercise therapy programs alone in patients with hip or knee osteoarthritis. DATA SYNTHESIS: The data were combined using random-effects meta-analyses where appropriate. The certainty of evidence for each outcome was judged using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. RESULTS: We included 19 trials. There was very low to moderate certainty of evidence that MT added benefit in the short term for pain, and combined pain, function, and stiffness (WOMAC global scale), but not for performance-based function and self-reported function. In the medium term, there was low- to very-low-certainty evidence that MT added benefit for performance-based function and WOMAC global score, but not for pain. There was high-certainty evidence that MT provided no added benefit in the long term for pain and function. CONCLUSION: There was very low to moderate certainty of evidence supporting MT as an adjunct to exercise therapy for pain and WOMAC global scale, but not function in patients with knee or hip osteoarthritis in the short term. There was high certainty of evidence of no benefit for additional MT over exercise therapy alone in the long term. J Orthop Sports Phys Ther 2022;52(10):675-684.

Patients' and clinicians' experiences with stratified exercise therapy in knee osteoarthritis: a qualitative study

Background

We have developed a model of stratified exercise therapy that distinguishes three knee osteoarthritis (OA) subgroups (‘high muscle strength subgroup’, ‘low muscle strength subgroup’, ‘obesity subgroup’), which are provided subgroup-specific exercise therapy (supplemented by a dietary intervention for the ‘obesity subgroup’). In a large clinical trial, this intervention was found to be no more effective than usual exercise therapy. The present qualitative study aimed to explore experiences from users of this intervention, in order to identify possible improvements.

Methods

Qualitative research design embedded within a cluster randomized controlled trial in a primary care setting. A random sample from the experimental arm (i.e., 15 patients, 11 physiotherapists and 5 dieticians) was interviewed on their experiences with receiving or applying the intervention. Qualitative data from these semi-structured interviews were thematically analysed.

Results

We identified four themes: one theme regarding the positive experiences with the intervention and three themes regarding perceived barriers. Although users from all 3 perspectives (patients, physiotherapists and dieticians) generally perceived the intervention as having added value, we also identified several barriers, especially for the ‘obesity subgroup’. In this ‘obesity subgroup’, physiotherapists perceived obesity as difficult to address, dieticians reported that more consultations are needed to reach sustainable weight loss and both physiotherapists and dieticians reported a lack of interprofessional collaboration. In the ‘high muscle strength subgroup’, the low number of supervised sessions was perceived as a barrier by some patients and physiotherapists, but as a facilitator by others. A final theme addressed barriers to knee OA treatment in general, with lack of motivation as the most prominent of these.

Conclusion

Our qualitative study revealed a number of barriers to effective application of the stratified exercise therapy, especially for the ‘obesity subgroup’. Based on these barriers, the intervention and its implementation could possibly be improved. Moreover, these barriers are likely to account at least partly for the lack of superiority over usual exercise therapy.

The Effectiveness of Fluoroscopically Guided Genicular Nerve Radiofrequency Ablation for the Treatment of Chronic Knee Pain Due to Osteoarthritis: A Systematic Review

ABSTRACT

The objective was to determine the effectiveness of fluoroscopically guided genicular nerve radiofrequency ablation for painful knee osteoarthritis. Primary outcome measure was improvement in pain after 6 mos. Secondary outcomes included the Oxford Knee Score and Western Ontario and McMaster Universities Osteoarthritis Index. Two reviewers independently assessed publications before October 10, 2020. The Cochrane Risk of Bias Tool and Grades of Recommendation, Assessment, Development, and Evaluation system were used. One hundred ninety-nine publications were screened, and nine were included. Six-month success rates for 50% or greater pain relief after radiofrequency ablation ranged from 49% to 74%. When compared with intra-articular steroid injection, the probability of success was 4.5 times higher for radiofrequency ablation (relative risk = 4.58 [95% confidence interval = 2.61-8.04]). When radiofrequency ablation was compared with hyaluronic acid injection, the probability of treatment success was 1.8 times higher (relative risk = 1.88, 95% confidence interval = 1.38-2.57). The group mean Oxford Knee Score and Western Ontario and McMaster Universities Osteoarthritis Index scores improved in participants receiving genicular radiofrequency ablation compared with intra-articular steroid injection and hyaluronic acid injection. According to Grades of Recommendation, Assessment, Development, and Evaluation, there is moderate-quality evidence that fluoroscopically guided genicular radiofrequency ablation is effective for reducing pain associated with knee osteoarthritis at minimum of 6 mos. Further research is likely to have an important impact on the current understanding of the long-term effectiveness of this treatment.

Effects of booster sessions on self-management interventions for chronic musculoskeletal pain: a systematic review and meta-analysis of randomised controlled trials

ABSTRACT

Our objective was to investigate the effectiveness of booster sessions after self-management interventions as a means of maintaining self-management behaviours in the treatment of chronic musculoskeletal pain. We searched MEDLINE, EMBASE, Science Citation Index, Cochrane Central Register of Controlled Trials, and PsychINFO. Two authors independently identified eligible trials and collected data. We calculated the odds ratio for the analyses of dichotomous data and standardised mean differences (SMDs) with 95% confidence interval (CI) for continuous variables. Our search identified 14 studies with a total of 1695 patients. All studies were at high risk of bias and provided very low quality evidence. For the primary outcomes, booster sessions had no evidence of an effect on improving patient-reported outcomes on physical function (SMD -0.13, 95% CI -0.32 to -0.06; P = 0.18), pain-related disability (SMD -0.16, 95% CI -0.36 to 0.03; P = 0.11), and pain self-efficacy (SMD 0.15, 95% CI -0.07 to 0.36; P = 0.18). For the secondary outcomes, booster sessions caused a significant reduction in patient-reported pain catastrophising (SMD -0.42, 95% CI -0.64 to -0.19; P = 0.0004) and no evidence of an effect on patient-reported pain intensity, depression, coping, or treatment adherence. There is currently little evidence that booster sessions are an effective way to prolong positive treatment effects or improve symptoms of long-term musculoskeletal conditions after self-management interventions. However, the studies were few with high heterogeneity, high risk of bias, and overall low quality of evidence. Our review argues against including booster sessions routinely to self-management interventions for the purpose of behaviour maintenance.

Patellar inward pushing method relieves knee osteoarthritis via regulating cytokines

BACKGROUND

Knee osteoarthritis (KOA) is a chronic degenerative disease characterized by pain, morning stiffness and swelling in the knee joints. And KOA is common in the elderly and seriously affects the exercise function and physical health of patients. This study aimed to explore the curative effects of patellar inward pushing method (PIPM) on KOA.

MATERIAL AND METHOD

In this study, we established rabbit animal models of KOA for the research by using the New Zealand white rabbits. 30 New Zealand white rabbits were divided into 5 groups by random number table method: blank group, model group, glucosamine hydrochloride (GH) group, PIPM group and PIPM combined with GH group, then the rabbits were modeled.

RESULTS

After 9-weeks cultured in groups, 5 ml blood was collected from the heart, and cytokines were detected. The result suggested that iNOS, NO and TNF-α were the pathogenic inflammatory factor of KOA, and aggravated cartilage damage and degeneration. Besides, this study indicated that PIPM combined with GH treatment significantly reduced the activity of inflammatory cytokines in serum and joint fluid of KOA models in rabbits. In addition, PIPM combined with GH therapy exhibited the best therapeutic effect among these treatments, which was working on KOA better than PIPM treatment alone or GH treatment alone.

CONCLUSIONS

PIPM could effective treat KOA via regulating cytokines, and the PIPM combined with GH therapy could be a novel therapeutic strategy of KOA.

Are manual therapy or booster sessions worthwhile in addition to exercise therapy for knee osteoarthritis: Economic evaluation and 2-year follow-up of a randomized controlled trial

BACKGROUND

Exercise therapy is known to be an effective intervention for patients with osteoarthritis, however the evidence is limited as to whether adding manual therapy or booster sessions are cost-effective strategies to extend the duration of benefits.

OBJECTIVE

To investigate the cost-effectiveness, at 2-year follow-up, of adding manual therapy and/or booster sessions to exercise therapy.

DESIGN

2-by-2 factorial randomized controlled trial.

METHODS

Participants with knee osteoarthritis were randomly allocated (1:1:1:1) to: exercise therapy delivered in consecutive sessions within 9 weeks (control group), exercise therapy distributed over 1 year using booster sessions, exercise therapy plus manual therapy delivered within 9 weeks, and exercise therapy plus manual therapy with booster sessions. The primary outcome was incremental cost-effectiveness from health system and societal perspectives interpreted as incremental net monetary benefit (INMB).

RESULTS

Of 75 participants, 66 (88 %) were retained at 1-year and 40 (53 %) at 2-year follow-up. All three interventions were cost-effective from both the health system and societal perspectives (INMBs, at 0.5 × GDP/capita willingness to pay (WTP) threshold: $3278 (95%CI -3244 to 9800) and $3904 (95%CI -2823 to 10,632) respectively for booster sessions; $2941 (95%CI -3686 to 9568) and $2618 (95%CI -4005 to 9241) for manual therapy; $270 (95%CI -6139 to 6679) and $404 (95%CI -6097 to 6905) for manual therapy with booster sessions).

CONCLUSION

Manual therapy or booster sessions in addition to exercise therapy are cost-effective at 2-year follow-up. The evidence did not support combining both booster sessions and manual therapy in addition to exercise therapy.

Insulin-like growth factor-1 regulates the mechanosensitivity of chondrocytes by modulating TRPV4

Both mechanical and biochemical stimulation are required for maintaining the integrity of articular cartilage. However, chondrocytes respond differently to mechanical stimuli in osteoarthritic cartilage when biochemical signaling pathways, such as Insulin-like Growth Factor-1 (IGF-1), are altered. The Transient Receptor Potential Vanilloid 4 (TRPV4) channel is central to chondrocyte mechanotransduction and regulation of cartilage homeostasis. Here, we propose that changes in IGF-1 can modulate TRPV4 channel activity. We demonstrate that physiologic levels of IGF-1 suppress hypotonic-induced TRPV4 currents and intracellular calcium flux by increasing apparent cell stiffness that correlates with actin stress fiber formation. Disruption of F-actin following IGF-1 treatment results in the return of the intracellular calcium response to hypotonic swelling. Using point mutations of the TRPV4 channel at the microtubule-associated protein 7 (MAP-7) site shows that regulation of TRPV4 by actin is mediated via the interaction of actin with the MAP-7 domain of TRPV4. We further highlight that ATP release, a down-stream response to mechanical stimulation in chondrocytes, is mediated by TRPV4 during hypotonic challenge. This response is significantly abrogated with IGF-1 treatment. As chondrocyte mechanosensitivity is greatly altered during osteoarthritis progression, IGF-1 presents as a promising candidate for prevention and treatment of articular cartilage damage.

The Efficacy of Manual Therapy in Patients with Knee Osteoarthritis: A Systematic Review

Background and objectives: Osteoarthritis (OA) is among the most common degenerative diseases that induce pain, stiffness and reduced functionality. Various physiotherapy techniques and methods have been used for the treatment of OA, including soft tissue techniques, therapeutic exercises, and manual techniques. The primary aim of this systemic review was to evaluate the short-and long-term efficacy of manual therapy (MT) in patients with knee OA in terms of decreasing pain and improving knee range of motion (ROM) and functionality. Materials and Methods: A computerised search on the PubMed, PEDro and CENTRAL databases was performed to identify controlled randomised clinical trials (RCTs) that focused on MT applications in patients with knee OA. The keywords used were 'knee OA', 'knee arthritis', 'MT', 'mobilisation', 'ROM' and 'WOMAC'. Results: Six RCTs and randomised crossover studies met the inclusion criteria and were included in the final analysis. The available studies indicated that MT can induce a short-term reduction in pain and an increase in knee ROM and functionality in patients with knee OA. Conclusions: MT techniques can contribute positively to the treatment of patients with knee OA by reducing pain and increasing functionality. Further research is needed to strengthen these findings by comparing the efficacy of MT with those of other therapeutic techniques and methods, both in the short and long terms.

Long-term effect of high-intensity laser therapy for persistent shoulder pain: A case report

BACKGROUND AND OBJECTIVE

This case report describes the long-term effect of the high-intensity laser therapy (HILT) in a patient with chronic shoulder pain refractory in comparison to other treatments.

CASE DESCRIPTION

Ten sessions of HILT were applied in a thirty-one-year-old woman diagnosed with subacromial syndrome. Assessment was carried out through different tests: Shoulder Pain and Disability Index (SPADI), Numeric Pain Rating Scale (NPRS) and pressure pain threshold (PPT). All measurements were taken at four different points: at the end of the 10 sessions, after one month, three months after the intervention and nine months after the initial intervention.

RESULTS

There was a clinically significant improvement in NPRS (decrease of 5 points), PPT (increase of 1.5 kg/cm2) and SPADI (decrease of 24 points) one month after the intervention. After three months, the increase of NPRS and SPADI required a 5-session intervention to support the clinical improvement. Six months after these booster sessions an increase in PPT and a decrease in NPRS and SPADI were observed.

CONCLUSION

Results indicate the suitability of developing new research lines which will optimize the use of HILT.

Predicting Recurrent Care Seeking of Physical Therapy for Musculoskeletal Pain Conditions

OBJECTIVE

Musculoskeletal pain conditions are a leading cause of pain and disability internationally and a common reason to seek health care. Accurate prediction of recurrence of health care seeking due to musculoskeletal conditions could allow for better tailoring of treatment. The aim of this project was to characterize patterns of recurrent physical therapy seeking for musculoskeletal pain conditions and to develop a preliminary prediction model to identify those at increased risk of recurrent care seeking.

DESIGN

Retrospective cohort.

SETTING

Ambulatory care.

SUBJECTS

Patients (n = 578,461) seeking outpatient physical therapy (United States).

METHODS

Potential predictor variables were extracted from the electronic medical record, and patients were placed into three different recurrent care categories. Logistic regression models were used to identify individual predictors of recurrent care seeking, and the least absolute shrinkage and selection operator (LASSO) was used to develop multivariate prediction models.

RESULTS

The accuracy of models for different definitions of recurrent care ranged from 0.59 to 0.64 (c-statistic), and individual predictors were identified from multivariate models. Predictors of increased risk of recurrent care included receiving workers' compensation and Medicare insurance, having comorbid arthritis, being postoperative at the time of the first episode, age range of 44-64 years, and reporting night sweats or night pain. Predictors of decreased risk of recurrent care included lumbar pain, chronic injury, neck pain, pregnancy, age range of 25-44 years, and smoking.

CONCLUSION

This analysis identified a preliminary predictive model for recurrence of care seeking of physical therapy, but model accuracy needs to improve to better guide clinical decision-making.

The effect of an integrated multidisciplinary rehabilitation programme for patients with chronic low back pain: Long-term follow up of a randomised controlled trial

Objective:

To compare the long-term effectiveness of an integrated rehabilitation programme with an existing rehabilitation programme, in terms of back-specific disability, in patients with chronic low back pain.

Design:

A single-centre, pragmatic, two-arm parallel, randomised controlled trial.

Setting:

A rheumatology rehabilitation centre in Denmark.

Subjects:

A total of 165 adults (aged ⩾ 18 years) with chronic low back pain.

Interventions:

An integrated programme (a pre-admission day, two weeks at home, two weeks inpatient followed by home-based activities, plus two 2-day inpatient booster sessions, and six-month follow-up visit) was compared with an existing programme (four-week inpatient, and six-month follow-up visit).

Main measure:

The primary outcome was disability measured using the Oswestry Disability Index after one year. Secondary outcomes included pain intensity (Numerical Rating Scale), pain self-efficacy (Pain Self-Efficacy Questionnaire), health-related quality of life (EuroQol-5 Domain 5-level (EQ-5D)), and depression (Major Depression Inventory). Analysis was by intention-to-treat, using linear mixed models.

Results:

303 patients were assessed for eligibility of whom 165 patients (mean age 50 years (SD 13) with a mean Oswestry Disability Index score of 42 (SD 11)) were randomly allocated (1:1 ratio) to the integrated programme (n = 82) or the existing programme (n = 83). The mean difference (integrated programme minus existing programme) in disability was –0.53 (95% CI –4.08 to 3.02); p = 0.770). No statistically significant differences were found in the secondary outcomes.

Conclusion:

The integrated programme was not more effective in reducing long-term disability in patients with chronic low back pain than the existing programme.

Evaluation of a novel strategy to implement exercise evidence into clinical practice in breast cancer care: protocol for the NEXT-BRCA randomised controlled trial

INTRODUCTION

The burden of breast cancer in Canada is steadily growing. More women are surviving breast cancer, yet, survivors live with side effects for years after treatments have ended. The benefits of exercise for women with breast cancer are well established and include improvement in treatment-related physical and emotional side effects. Despite these benefits, few survivors meet exercise guidelines. Exercise programmes are needed within the cancer institution in Canada to bridge the current knowledge to practice gap. The purpose of this study is to test the effects of a novel implementation strategy that includes institution-based exercise plus self-management (SM) or SM alone versus usual care in improving exercise level, quality of life, aerobic capacity, muscle strength and use of healthcare services over 12 months for women with breast cancer receiving chemotherapy.

METHODS AND ANALYSIS

Participants: Women with stages I-III breast cancer undergoing chemotherapy. Intervention: Group 1: institution-based exercise and SM (8 exercise sessions plus 8 SM modules); Group 2: SM alone; Group 3: usual care. Outcomes: The primary effectiveness outcome is minutes per week of moderate to vigorous physical activity. Secondary outcomes include quality of life, aerobic capacity, muscle strength, and use of healthcare services. Randomisation: Participants will be randomised (1:1:1) to one of the three groups by a blinded statistician and will be stratified based on age of participant (<40, 40-60, and >60 years). Statistical analysis: Outcomes will be measured at baseline, post-intervention, 6-month and 12-month follow-up using an analysis of covariance to test changes between groups over time adjusted for age.

ETHICS AND DISSEMINATION

This study addresses a long-standing need to help women with breast cancer undergoing chemotherapy become and stay more active by implementing novel rehabilitation strategies into real-world practice. This is vital in order for this population to minimise the lingering side effects of treatment, improve function and quality of life and prevent cancer recurrence.

TRIAL REGISTRATION NUMBER

The study protocol (v1: July 2020) has been registered on ClinicalTrials.gov (NCT04109274).

Feasibility and Effectiveness of Implementing a Novel Exercise and Self-Management Programme during Chemotherapy for Women with Breast Cancer: A Pilot Randomized Controlled Trial

Purpose: The aim of this study was to determine the feasibility and effectiveness of implementing a novel exercise and self-management programme for women with breast cancer during chemotherapy. Method: The study used a pilot implementation design with a randomized controlled trial methodology. The 26 participants were adult breast cancer survivors (Stages 1-3) undergoing chemotherapy treatment. The intervention group received eight sessions of individualized, supervised, moderate-intensity aerobic exercise, paired with self-management modules in the cancer institution; the comparison group received usual care. The primary outcome assessed was feasibility of the implementation strategies. The secondary outcomes - level of physical activity, quality of life, exercise knowledge and behaviour, and perception of health status - were assessed at baseline, post-intervention, and 2- and 4-month follow-up. Descriptive statistics were used to measure the feasibility outcomes (recruitment rate, retention rate, adherence rate, and number of adverse events). A repeated-measures analysis of covariance was used to compare the secondary outcomes between the intervention and control groups at various time points. Results: The recruitment rate was 96%, retention rate was 100%, and adherence rate was 89%. No adverse events occurred. A between-groups difference was found for levels of physical activity post-intervention (mean difference = 25.38 points on the Godin Leisure-Time Exercise Questionnaire; 95% CI: 9.34, 41.42). There were no other significant findings. Conclusions: The implementation strategy was feasible. This programme has the potential to improve women's physical activity level during chemotherapy. Further research is needed to determine strategies to help survivors maintain these results over the long term.

Current physical therapy care of patients undergoing breast reconstruction for breast cancer: a survey of practice in the United Kingdom and Brazil

BACKGROUND

In both the United Kingdom (UK) and Brazil, women undergoing mastectomy should be offered breast reconstruction. Patients may benefit from physical therapy to prevent and treat muscular deficits. However, there are uncertainties regarding which physical therapy program to recommend.

OBJECTIVE

The aim was to investigate the clinical practice of physical therapists for patients undergoing breast reconstruction for breast cancer. A secondary aim was to compare physical therapy practice between UK and Brazil.

METHODS

Online survey with physical therapists in both countries. We asked about physical therapists' clinical practice.

RESULTS

181 physical therapists completed the survey, the majority were from Brazil (77%). Respondents reported that only half of women having breast reconstruction were routinely referred to physical therapy postoperatively. Contact with patients varied widely between countries, the mean number of postoperative sessions was 5.7 in the UK and 15.1 in Brazil. The exercise programs were similar for different reconstruction operations. Therapists described a progressive loading structure over time: range of motion (ROM) was restricted to 90° of arm elevation in the first two postoperative weeks; by 2-4 weeks ROM was unrestricted; at 1-3 months muscle strengthening was initiated, and after three months the focus was on sports-specific activities.

CONCLUSION

Only half of patients having a breast reconstruction are routinely referred to physical therapy. Patients in Brazil have more intensive follow-up, with up to three times more face-to-face contact with a physical therapist than in the UK. Current practice broadly follows programs for mastectomy care rather than being specific to reconstruction surgery.

Cryotherapy associated with tailored land-based exercises for knee osteoarthritis: a protocol for a double-blind sham-controlled randomised trial

INTRODUCTION

There is an unmet need to develop tailored therapeutic exercise protocols applying different treatment parameters and modalities for individuals with knee osteoarthritis (KOA). Cryotherapy is widely used in rehabilitation as an adjunct treatment due to its effects on pain and the inflammatory process. However, disagreement between KOA guidelines remains with respect to its recommendation status. The aim of this study is to verify the complementary effects of cryotherapy when associated with a tailored therapeutic exercise protocol for patients with KOA.

METHODS AND ANALYSIS

This study is a sham-controlled randomised trial with concealed allocation and intention-to-treat analysis. Assessments will be performed at baseline and immediately following the intervention period. To check for residual effects of the applied interventions, 3-month and 6-month follow-up assessments will be performed. Participants will be community members living with KOA divided into three groups: (1) the experimental group that will receive a tailored therapeutic exercise protocol followed by a cryotherapy session of 20 min; (2) the sham control group that will receive the same regimen as the first group, but with sham packs filled with dry sand and (3) the active treatment control group that will receive only the therapeutic exercise protocol. The primary outcome will be pain intensity according to a Visual Analogue Scale. Secondary outcomes will be the Western Ontario & McMaster Universities Osteoarthritis Index; the Short-Form Health Survey 36; the 30-s Chair Stand Test; the Stair Climb test; and the 40-m fast-paced walk test.

ETHICS AND DISSEMINATION

The trial was approved by the Institutional Ethics Committee of Federal University of São Carlos, São Paulo, Brazil. Registration approval number: CAAE: 65966617.9.0000.5504. The results will be published in peer-reviewed journals.

TRIAL REGISTRATION NUMBER

Photobiomodulation therapy associated with supervised therapeutic exercises for people with knee osteoarthritis: a randomised controlled trial protocol

BACKGROUND

Physical exercise, a cornerstone of the conservative management of knee osteoarthritis (KOA), is exhaustively recommended by important clinical guidelines. A strength therapeutic exercise program (STEP) relieves pain, improves physical function and ultimately ameliorates quality of life (QoL). Furthermore, photobiomodulation (PBM) has been used as an adjunct treatment for people with KOA; however, there are still controversial recommendations regarding its use on this population. Thus, we hypothesised that PBM, when associated with a STEP protocol on patients with KOA, could induce better clinical outcomes than a STEP protocol alone.

METHODS AND ANALYSIS

The study is a 6-month triple-blind placebo-controlled randomised clinical trial with intention-to-treat analysis. The trial will include 120 people with clinic and radiographic signs of KOA. The intervention consists of a supervised STEP and PBM protocols conducted over an 8-week intervention period. Assessments are performed at baseline, right after treatment, and 3-month and 6-month follow-up periods. The primary clinical outcome is pain intensity according to a 10 cm Visual Analogue Scale. Secondary outcomes are the global Western Ontario & McMaster Universities Osteoarthritis Index; QoL assessed by the 36-item Short-Form health survey questionnaire; and performance-based physical parameters assessed by the 30 s chair stand test; the stair climb test; and the 40 m fast-paced walk test.

ETHICS AND DISSEMINATION

The trial was approved by the Human Research Ethics Committee of the Federal University of São Carlos, São Paulo, Brazil (REC no 2.016.122). Results will be published in peer-reviewed journals.

TRIAL REGISTRATION NUMBER

Brazilian Clinical Trials Registry (U1111-1215-6510).

Effects of manual therapies on stability in people with musculoskeletal pain: a systematic review

Introduction

Chronic musculoskeletal pain is associated with reduced balance performance and falls risk. Manual therapies are commonly used interventions for musculoskeletal pain. There is emerging evidence that manual therapies may improve balance. The aim of this systematic review was to examine the effectiveness of manual therapies for musculoskeletal pain on measures of static and dynamic stability.

Methods

Six electronic databases were searched using pre-defined eligibility criteria and two independent reviewers assessed all identified records. Risk of bias was assessed using the 12-item Cochrane Risk of Bias assessment by two authors independently and any discrepancies resolved through consensus. Meta-analysis was conducted when three or more studies used the same outcome measures including gait speed, timed up and go test, step test and sit-to-stand test.

Results

Twenty-six studies were included in the analysis. Both spinal and extremity musculoskeletal pain conditions were represented. Manual therapies included manipulation, mobilisation and massage. The most common intervention compared to manual therapy was exercise. Outcome measures included both clinical and objective measures of stability. Overall the risk of bias was reported as generally low or unclear.

Conclusion

Improvement in stability measures were reported in studies comparing manual therapy in the short term, but not long-term follow-up. There was no clear association between significant pain reduction and measures of stability. Further prospective studies are recommended to investigate whether manual therapies should be part of an integrative healthcare plan for risk of falls management and when a transition from manual therapy to more active interventions should occur for long term management.

The effect of an integrated multidisciplinary rehabilitation programme alternating inpatient interventions with home-based activities for patients with chronic low back pain: a randomized controlled trial

Objective:

To compare the effectiveness of an integrated rehabilitation programme with an existing rehabilitation programme in patients with chronic low back pain.

Design:

A single-centre, pragmatic, two-arm parallel, randomized controlled trial (1:1 ratio).

Setting:

A rheumatology inpatient rehabilitation centre in Denmark.

Subjects:

A total of 165 adults (aged ⩾ 18 years) with chronic low back pain.

Interventions:

An integrated rehabilitation programme comprising an alternation of three weeks of inpatient stay and 12 weeks of home-based activities was compared with an existing rehabilitation programme of four weeks of inpatient stay.

Main measures:

Patient-reported outcomes were collected at baseline and at the 26-week follow-up. The primary outcome was back-specific disability (Oswestry Disability Index). Secondary outcomes included pain intensity (Numerical Rating Scale), pain self-efficacy (Pain Self-Efficacy Questionnaire), health-related quality of life (EuroQol-5 Domain 5-level (EQ-5D)), and depression (Major Depression Inventory). A complete case analysis was performed.

Results:

A total of 303 patients were assessed for eligibility of whom 165 (mean age: 50 years (SD 13) and mean Oswestry Disability Index score 42 (SD 11)) were randomized (83 to existing rehabilitation programme and 82 to integrated rehabilitation programme). Overall, 139 patients provided the 26-week follow-up data. Baseline demographic and clinical characteristics were comparable between programmes. The between-group difference in the Oswestry Disability Index score when adjusting for the corresponding baseline score was −0.28 (95% confidence interval (CI): −4.02, 3.45) which was neither statistically nor clinically significant. No significant differences were found in the secondary outcomes.

Conclusion:

An integrated rehabilitation programme was no more effective than an existing rehabilitation programme at the 26-week follow-up.

Patient and Parent Perceptions of Rehabilitation Factors That Influence Outcomes After Anterior Cruciate Ligament Reconstruction and Clearance to Return to Sport in Adolescents and Young Adults

BACKGROUND

Wide variation in outcomes after anterior cruciate ligament reconstruction (ACLR) exists among adolescents and young adults. However, little evidence is available regarding key rehabilitation factors that may be driving these differences.

OBJECTIVE

To explore patient and parent perceptions of key rehabilitation drivers related to outcomes after ACLR.

METHODS

In this qualitative study, which used an interpretive phenomenological methodology, semi-structured interviews were conducted with patients who had returned to sport after ACLR and with their parents. The interviews asked about respondents' experience with physical therapy and how it related to their outcomes after ACLR. The interviews were recorded, transcribed, and coded. Themes were then identified using open and axial coding processes.

RESULTS

There were 3 primary themes that patients and parents perceived as key factors influencing their rehabilitation outcomes after ACLR: (1) patient attributes (ie, motivation, confidence, accountability, access to resources, and social support), (2) physical therapist-patient relationship qualities (physical therapist as guide, motivator, booster of confidence, fosterer of perseverance, and coordinator of care), and (3) elements of the system (ie, availability and utilization of therapy visits, clinic environment, and coordination among care providers).

CONCLUSION

Patient and parent perspectives of key drivers that influence ACLR rehabilitation outcomes include patient, therapist, and system factors. Developing specific strategies to target these factors may enhance patient and parent perceptions of the experience. The awareness gained from these results provides a foundation for future studies examining how these factors affect outcomes and how to improve rehabilitation after ACLR.

Incremental clinical effectiveness and cost effectiveness of providing supervised physiotherapy in addition to usual medical care in patients with osteoarthritis of the hip or knee: 2-year results of the MOA randomised controlled trial

OBJECTIVE

To investigate the clinical- and cost-effectiveness at 2-year follow-up of providing individual, supervised exercise physiotherapy and/or manual physiotherapy in addition to usual medical care.

METHOD

People with hip or knee osteoarthritis meeting the American College of Rheumatology clinical diagnostic criteria were randomised (1:1, concealed, assessor-blinded) to four groups: usual medical care; supervised exercise physiotherapy; manual physiotherapy; or combined exercise and manual physiotherapy. Physiotherapy group participants were provided 10 50-min treatment sessions including booster sessions at 4 and 13 months, in addition to usual care. The primary outcome at 2-year follow-up was incremental cost-utility ratio (ICUR) of each physiotherapy intervention in addition to usual care, compared with usual care alone, from the health system and societal perspectives. To allow interpretation of negative ICURs, we report incremental net benefit (INB). The primary clinical outcome was the Western Ontario and McMaster Osteoarthritis Index (WOMAC).

RESULTS

Of 206 patients, 186 (90·3%) were retained at 2-year follow-up. Exercise physiotherapy and manual physiotherapy dominated usual care, demonstrating cost savings; combined therapy did not. Exercise therapy had the highest incremental net benefits (INBs), statistically significant at all willingness-to-pay (base-case: societal New Zealand (NZ)$6,312, 95%CI 334 to 12,279; health system NZ$8,065, 95%CI 136 to 15,994). Clinical improvements were superior to usual care only in the exercise physiotherapy group (-28.2 WOMAC points, 95%CI -49.2 to -7.1). No serious adverse events were recorded.

CONCLUSION

Individually supervised exercise therapy is cost-effective and clinically effective in addition to usual medical care at 2-year follow-up, and leads to cost savings for the health system and society.

Is a model of stratified exercise therapy by physical therapists in primary care feasible in patients with knee osteoarthritis? : a mixed methods study

OBJECTIVES

To explore the feasibility of a newly developed model of stratified exercise therapy in primary care for patients with knee osteoarthritis (OA).

DESIGN

Mixed method design (process, outcome and qualitative evaluation).

SETTING

Six physical therapy practices in primary care around Amsterdam.

PARTICIPANTS

Fifty eligible patients with knee OA, visiting one of the participating physical therapists (PTs).

INTERVENTION

Patients were allocated to a subgroup based on a simple stratification tool and received subgroup-specific, protocolized, 4-month, exercise therapy.

MAIN OUTCOME MEASURES

Feasibility of this model of stratified exercise therapy was explored by multiple process parameters, outcome measures (physical functioning and knee pain; at baseline and 4-months follow-up) and experiences from patients and PTs.

RESULTS

From 97 potentially eligible patients, fifty patients were included and allocated to the 'high muscle strength subgroup' (n=17), 'depression subgroup' (n=4), 'obesity subgroup' (n=6) or 'low muscle strength subgroup' (n=23). Three patients dropped out during the study period. PTs provided relatively low numbers of sessions (on average 10 sessions), although exceedance of the recommended maximum number of sessions did occur frequently. We found clinically relevant improvements on physical functioning and knee pain (P<0.001 for both) for the total group. In general, the model of stratified exercise therapy was considered to be easily applicable and of added value for daily practice.

CONCLUSIONS

Our model of stratified exercise therapy seems to be feasible in primary care, although a number of limitations were reported. Future research should determine the (cost-)effectiveness of an adapted model, compared to usual, non-stratified exercise therapy.

On the biomechanical relationship between applied hip, knee and ankle joint moments and the internal knee compressive forces

Mechanical devices are common treating methods for knee osteoarthritis. It has the purpose of reducing the internal joint forces and unloading the damaged structure. The reduction is often achieved by alterations in the frontal plan, shifting the contact force from one compartment to the other, leaving the total compressive force unchanged. The aim of this study was to investigate how internal knee joint forces depend on applied external moments during gait. Musculoskeletal models of the gait of 10 healthy subjects were developed in the AnyBody Modelling System and used to simulate applied joint moments about different axes (load cases), each with the magnitude to compensate the net moment about the respective axis by a specified percentage. For each load case, the total, medial and lateral knee compressive force were computed and compared with a baseline case with no external moments applied. Among the investigated moments, hip flexion-extension, knee flexion-extension and ankle plantarflexion-dorsiflexion moment compensations have the most positive impact on the total knee joint compressive force, and combining the 3, each with a 40% compensation of the muscle moments, reduced the first peak by 23.6%, the second by 30.6% and the impulse by 28.6% with respect to no applied moments.

Individuals with lumbar spinal stenosis seek education and care focused on self-management-results of focus groups among participants enrolled in a randomized controlled trial

BACKGROUND CONTEXT

The effectiveness of treatments for chronic, degenerative conditions of the lumbar spine can be influenced by patient perceptions and expectations regarding treatment.

PURPOSE

The primary purpose of this study was to understand the factors that are important to individuals with lumbar spinal stenosis (LSS) regarding different nonsurgical treatments. These factors were considered within the context of each treatment received as a part of the parent randomized controlled trial (RCT).

STUDY DESIGN

Focus group study of RCT participants.

PATIENT SAMPLE

Convenience sample of 50 individuals with LSS (28 female, average age 73±7.7 years) from an RCT participated in one of six focus groups. Focus groups consisted of patients previously randomized to one of three nonsurgical treatments: (1) medical care; (2) community-based group exercise; and (3) clinic-based manual therapy and individualized exercise.

OUTCOME MEASURES

Experiences, opinions, and preferences of individuals with LSS who participated in an RCT. Inter-coder agreement for qualitative analysis was conducted with kappa statistics.

METHODS

Participants discussed their experiences and perceptions regarding study treatment and their general experience with LSS using open-ended questions provided by a facilitator. Transcripts were coded according to modified grounded theory in an open approach, using codes that addressed the primary focus group discussion topics (primary coding) and codes for emerging topics (secondary coding). Secondary coding sought to identify themes concerning living with LSS and seeking treatment that were emergent from the focus groups. This study was funded by the Patient-Centered Research Outcomes Institute. The authors report no conflicts of interest.

RESULTS

Three themes related to medical treatment and symptom management arose from analyses: (1) an emotional response to LSS; (2) a desire for education about LSS and motivation to pursue education from any available source; and (3) a desire for individualized care based on self-management techniques and lifestyle changes. Emotional responses were more evident in individuals receiving medical care, whereas the other two themes were consistent across all three treatment groups.

CONCLUSIONS

The chronic pain associated with LSS may result in negative emotional responses. Individuals with LSS may believe misinformation and information from nonmedical sources, especially when medical providers do not spend sufficient time explaining the disease process and the reasoning behind treatment strategies. Receiving individualized care focused on self-management led to fewer negative emotions toward care and the disease process. Clinicians should be prepared to address all three of these aspects when providing care to individuals with LSS.

Effects of orthopaedic manual therapy in knee osteoarthritis: a systematic review and meta-analysis

OBJECTIVE

This systematic review to aimed to evaluate the effects of orthopaedic manual therapy (OMT) on pain, improving function, and physical performance in patients with knee osteoarthritis (OA).

DATA SOURCES

Four databases (PubMed, Web of Science, CENTRAL, and CINAHL) were searched.

STUDY SELECTION

Trials were required to compare OMT alone or OMT in combination with exercise therapy, with exercise therapy alone or control.

DATA EXTRACTION

Data extraction and risk assessment were done by two independent reviewers. Outcome measures were visual analogue scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score, WOMAC function score, WOMAC global score, and stairs ascending-descending time.

RESULTS

Eleven randomized controlled trials were included (494 subjects), four of which had a PEDro score of 6 or higher, indicating adequate quality. The results of the meta-analysis indicated that reduction of VAS score in OMT compared with the control group was statistically insignificant (SDM: -0.59; 95% CI: -1.54 to -0.36; P=0.224). The reduction of VAS score in OMT compared with exercise therapy group was statistically significant (SDM: -0.78; 95% CI: -1.42 to -0.17; P=0.013). The reduction of WOMAC pain score in OMT compared with the exercise therapy group was statistically significant (SDM: -0.79; 95% CI: -1.14 to -0.43; P=0.001). Similarly, the reduction of WOMAC function score in OMT compared with the exercise therapy group was statistically significant (SDM: -0.85; 95% CI: -1.20 to -0.50; P=0.001). However, the reduction of WOMAC global score in OMT compared with the exercise therapy group was statistically insignificant (SDM: -0.23; 95% CI: -0.54 to -0.09; P=0.164). The reduction of stairs ascending-descending time in OMT compared with the exercise therapy group was statistically significant (SDM: -0.88; 95% CI: -1.48 to -0.29; P=0.004).

CONCLUSIONS

This review indicated OMT compared with exercise therapy alone provides short-term benefits in reducing pain, improving function, and physical performance in patients with knee OA.

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.

Patients' experience with nonsurgical treatment for lumbar spinal stenosis: a qualitative study

BACKGROUND CONTEXT

Lumbar spinal stenosis (LSS) is a highly prevalent disease in older adults that causes significant limitations in walking and other daily activities. Research into optimal nonsurgical treatment approaches for LSS is lacking.

PURPOSE

The purpose of this qualitative study is to assess the opinions of participants in a randomized clinical trial of nonsurgical LSS treatments regarding the interventions they received, factors contributing to adherence to the interventions, and methods of outcomes assessment.

STUDY DESIGN/SETTING

This study used a qualitative focus group design conducted at an academic research center.

PATIENT SAMPLE

Individuals participating in a randomized clinical trial (RCT) for non-surgical LSS treatment were invited to discuss their study treatments and general experiences with LSS. The three treatment arms in the study were medical care, community-based group exercise, and clinic-based manual therapy and individual exercise.

OUTCOME MEASURES

Following coding of qualitative data, kappa statistic was used to calculate agreement between observers. Themes were identified and agreed upon by both coders.

METHODS

This study was funded by the Patient-Centered Outcomes Research Institute (PCORI). Fifty individuals (28 women, mean age 73±7.7 years) participated in a focus group. Two focus groups based on modified grounded theory were held for participants of each of the three treatment arms, for a total of six focus groups. Discussion topics included perceived effectiveness of the assigned treatment, suggestions for improvement, barriers and facilitators to completing treatment, and opinions of research outcome measures.

RESULTS

Several themes were evident across all treatment groups. First, patients prefer individualized treatment that is tailored to their specific impairments and functional limitations. They also want to learn self-management strategies to rely less upon formal health care providers. Participants consistently stated that exercise improved their pain levels and physical function. However, they noted that these effects are temporary, so commitment to exercising long-term is important. Common barriers to completing the assigned LSS treatment included transportation issues and other comorbid health conditions. All three treatment groups cited perceived treatment benefit as a strong facilitator to continuing treatment. In addition, the ability of the health care provider to relate to the patient and listen to the patient's concerns was a common facilitator. Within the community-based group exercise treatment arm, most individuals continued group exercise after study completion, and social support was often mentioned as a facilitator to continuing treatment. Medical care was most often associated with minimal to no effect of treatment.

CONCLUSIONS

Many individuals with LSS report barriers to accessing non-surgical treatment, but may also be willing to commit to a long-term treatment strategy that includes exercise. Social support from others with LSS and from health care providers with good communication skills may facilitate compliance with treatment recommendations.

The Influence of Exercise Dosing on Outcomes in Patients With Knee Disorders: A Systematic Review

Study Design Systematic review. Background Therapeutic exercise is commonly used to treat individuals with knee disorders, but dosing parameters for optimal outcomes are unclear. Large variations exist in exercise prescription, and research related to specific dosing variables for knee osteoarthritis, patellar tendinopathy, and patellofemoral pain is sparse. Objectives To identify specific doses of exercise related to improved outcomes of pain and function in individuals with common knee disorders, categorized by effect size. Methods Five electronic databases were searched for studies related to exercise and the 3 diagnoses. Means and standard deviations were used to calculate effect sizes for the exercise groups. The overall quality of evidence was assessed using the Physiotherapy Evidence Database scale. Results Five hundred eighty-three studies were found after the initial search, and 45 were included for analysis after screening. Physiotherapy Evidence Database scale scores were "fair" quality and ranged from 3 to 8. For knee osteoarthritis, 24 total therapeutic exercise sessions and 8- and 12-week durations of exercise were parameters most often associated with large effects. An exercise frequency of once per week was associated with no effect. No trends were seen with exercise dosing for patellar tendinopathy and patellofemoral pain. Conclusion This review suggests that there are clinically relevant exercise dosing variables that result in improved pain and function for patients with knee osteoarthritis, but optimal dosing is still unclear for patellar tendinopathy and patellofemoral pain. Prospective studies investigating dosing parameters are needed to confirm the results from this systematic review. Level of Evidence Therapy, level 1a. J Orthop Sports Phys Ther 2018;48(3):146-161.

Osteoarthritis year in review 2017: rehabilitation and outcomes

OBJECTIVE

The purpose of this systematic review was to describe studies examining rehabilitation for people with osteoarthritis (OA) and to summarize findings from selected key systematic reviews (SRs) and randomized controlled trials (RCTs).

DESIGN

A systematic search was performed using Pubmed, Embase and Cochrane databases from April 1^st 2016 to May 15^th 2017 using the terms 'osteoarthritis', 'randomized controlled trial', and 'systematic review'. Inclusion criteria were: clinically or radiologically diagnosed patients with OA, rehabilitation treatment, RCT or SRs. A selection of the included studies is discussed based on study quality and perceived importance to the field; including those that are innovative, inform the direction of the field or generate controversy. Methodological quality of the included studies was assessed using the PEDro-scale for RCTs and the Amstar guideline for SRs.

RESULTS

From 1211 articles, 80 articles met the eligibility criteria including 21 SRs and 61 RCTs. The median of the methodological quality of the SRs and RCTs was 7 (2-9) and 6 (3-10), respectively. The studies were grouped into several themes, covering the most important rehabilitation fields.

CONCLUSIONS

Striking is the small number of studies investigating another joint (18%) than the knee (82%). Exercise is the most common treatment evaluated and should be accompanied with education to effectuate a behavioural change in physical activity of people with OA. No new insights in the field of braces (or orthoses) and in the field of acupuncture were found.

Exercise, Manual Therapy, and Booster Sessions in Knee Osteoarthritis: Cost-Effectiveness Analysis From a Multicenter Randomized Controlled Trial

BACKGROUND

Limited information exists regarding the cost-effectiveness of rehabilitation strategies for individuals with knee osteoarthritis (OA).

OBJECTIVE

The study objective was to compare the cost-effectiveness of 4 different combinations of exercise, manual therapy, and booster sessions for individuals with knee OA.

DESIGN

This economic evaluation involved a cost-effectiveness analysis performed alongside a multicenter randomized controlled trial.

SETTING

The study took place in Pittsburgh, Pennsylvania; Salt Lake City, Utah; and San Antonio, Texas.

PARTICIPANTS

The study participants were 300 individuals taking part in a randomized controlled trial investigating various physical therapy strategies for knee OA.

INTERVENTION

Participants were randomized into 4 treatment groups: exercise only (EX), exercise plus booster sessions (EX+B), exercise plus manual therapy (EX+MT), and exercise plus manual therapy and booster sessions (EX+MT+B).

MEASUREMENTS

For the 2-year base case scenario, a Markov model was constructed using the United States societal perspective and a 3% discount rate for costs and quality-adjusted life years (QALYs). Incremental cost-effectiveness ratios were calculated to compare differences in cost per QALY gained among the 4 treatment strategies.

RESULTS

In the 2-year analysis, booster strategies (EX+MT+B and EX+B) dominated no-booster strategies, with both lower health care costs and greater effectiveness. EX+MT+B had the lowest total health care costs. EX+B cost[Formula: see text]1061 more and gained 0.082 more QALYs than EX+MT+B, for an incremental cost-effectiveness ratio of[Formula: see text]12,900/QALY gained.

LIMITATIONS

The small number of total knee arthroplasty surgeries received by individuals in this study made the assessment of whether any particular strategy was more successful at delaying or preventing surgery in individuals with knee OA difficult.

CONCLUSIONS

Spacing exercise-based physical therapy sessions over 12 months using periodic booster sessions was less costly and more effective over 2 years than strategies not containing booster sessions for individuals with knee OA.
