Efficacy of virtual reality exercise in knee osteoarthritis rehabilitation: a systematic review and meta-analysis

Background

This systematic review and meta-analysis aims to investigate the effects of virtual reality (VR) exercise compared to traditional rehabilitation on pain, function, and muscle strength in patients with knee osteoarthritis (KOA). Additionally, the study explores the mechanisms by which VR exercise contributes to the rehabilitation of KOA patients.

Methods

We systematically searched PubMed, the Cochrane Library, Embase, Web of Science, Scopus, and PEDro according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Our search spanned from the library construction to 24 May 2024, focusing on randomized controlled trials Primary outcomes included pain, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and muscle strength. Meta-analysis was conducted using RevMan (version 5.4) and Stata (version 14.0). The bias risk of included studies was assessed using the Cochrane RoB 2.0 tool, while the quality of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach.

Results

This meta-analysis and systematic review included nine studies involving 456 KOA patients. The results indicated that VR exercise significantly improved pain scores (SMD, -1.53; 95% CI: -2.50 to -0.55; p = 0.002), WOMAC total score (MD, -14.79; 95% CI: -28.26 to -1.33; p = 0.03), WOMAC pain score (MD, -0.93; 95% CI: -1.52 to -0.34; p = 0.002), knee extensor strength (SMD, 0.51; 95% CI: 0.14 to 0.87; p = 0.006), and knee flexor strength (SMD, 0.65; 95% CI: 0.28 to 1.01; p = 0.0005), but not significantly for WOMAC stiffness (MD, -0.01; 95% CI: -1.21 to 1.19; p = 0.99) and physical function (MD, -0.35; 95% CI: -0.79 to -0.09; p = 0.12).

Conclusion

VR exercise significantly alleviates pain, enhances muscle strength and WOMAC total score in KOA patients, but improvements in joint stiffness and physical function are not significant. However, the current number of studies is limited, necessitating further research to expand on the present findings.

Facilitators, barriers and support needs to GLA:D exercise adherence - a mixed method study

BACKGROUND

Knee and hip osteoarthritis (OA) are among the most common musculoskeletal joint diseases worldwide. International guidelines recommend exercise and education as first-line interventions for their management. The Good Life with osteoArthritis Denmark (GLA:D) programme aims to achieve self-management using group exercise and education sessions. It also encourages participants to stay physically active and perform GLA:D exercises (GE) twice weekly after programme end. This study investigated the participants' self-reported level of physical activity (PA) and self-reported adherence to the GE between five and 17 months after completion of the GLA:D programme and also explored the barriers, facilitators and support needs to achieve long-term adherence to GE.

METHODS

A mixed method study using an exploratory sequential design was performed. A qualitative phase, involving semi-structured interviews and a focus group, led to the development of a questionnaire on participants' level of PA, as well as ratings of the barriers, facilitators and support needs for the achievement of long-term adherence to GE. In a second quantitative phase, the survey was conducted online with former GLA:D participants from Switzerland. Descriptive statistical analysis and a group comparison between adherent and non-adherent participants to the GE were performed using Fisher's exact test, odds ratio, and confidence interval.

RESULTS

Eleven former GLA:D participants attended the interviews and focus group, and former GLA:D participants (30% response rate) participated in the survey. Of these, 84% (n = 285) reported to reach the recommended level of PA and 53% (n = 178) GE adherence. The top barrier to GE adherence was no/little self-discipline to perform GE (40%, n = 112) and the top facilitator was GE are easy to perform (93%, n = 300). The top 3 items regarding support needs to enhance GE adherence were a shortened version (max. 30 min) of the GE home programme (75%, n = 255), monthly continuation of small GE groups under GLA:D physiotherapists' supervision (65%, n = 221), and monitoring with regular testing of individual progress (65%, n = 221).

CONCLUSIONS

The top barriers and facilitators should be considered by those responsible for the GLA:D programme and may need to be specifically addressed during and after the programme. The development of a shortened version of the GLA:D programme, a post-GLA:D group, and monitoring with regular testing seem crucial for enhancing GE adherence.

Factors associated with empowerment after participating in a supported osteoarthritis self-management program: An explorative study

Objective

To explore factors associated with change in empowerment in patients that have participated in a 3-month Supported Osteoarthritis Self-Management Program (SOASP). Further, to evaluate empowerment in the longer term.

Design

An explorative analysis including patients from a cohort study conducted in primary healthcare in Sweden was performed. Univariable linear regression models were performed to assess associations between demographics and patient-reported outcome measures (explanatory factors), respectively, and change in empowerment from baseline to 3-month follow-up (outcome variable). Long-term follow-up of empowerment was at 9 months.

Results

Self-reported increase in enablement at the 3-month follow-up was associated with a greater improvement in empowerment (B ​= ​0.041, 95% CI (0.011, 0.07), p ​= ​0.008). Living alone was associated with less improvement in empowerment (B ​= ​-0.278, 95% CI (-0.469, -0.086), p ​= ​0.005) compared to living together. Physical exercise >120 ​min per week at baseline was associated with less improvement in empowerment (B ​= ​-0.293, 95% CI (-0.583, -0.004), p ​= ​0.047) compared to reporting no exercise at baseline. No other associations were observed (p ​> ​0.05). Empowerment improved from baseline to the 3-month follow-up (mean 0.20 (SD 0.5), p ​< ​0.001) but there was no change from baseline to the 9-month follow-up (mean 0.02 (SD 0.6), p ​= ​0.641).

Conclusions

Self-reported increased enablement may lead to greater improvement in empowerment after SOASP. Greater efforts may be needed to support those that live alone, are physically active, and to sustain empowerment in the longer term after SOASP. More research is needed on empowerment to provide personalized support for patients with OA after SOASP.

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.

Efficacy of interventions and techniques on adherence to physiotherapy in adults: an overview of systematic reviews and panoramic meta-analysis

BACKGROUND

Adherence to physiotherapeutic treatment and recommendations is crucial to achieving planned goals and desired health outcomes. This overview of systematic reviews synthesises the wide range of additional interventions and behaviour change techniques used in physiotherapy, exercise therapy and physical therapy to promote adherence and summarises the evidence of their efficacy.

METHODS

Seven databases (PEDro, PubMed, Cochrane Library, Web of Science, Scopus, PsycINFO and CINAHL) were systematically searched with terms related to physiotherapy, motivation, behaviour change, adherence and efficacy (last searched on January 31, 2023). Only systematic reviews of randomised control trials with adults were included. The screening process and quality assessment with AMSTAR-2 were conducted independently by the two authors. The extracted data was synthesised narratively. In addition, four meta-analyses were pooled in a panoramic meta-analysis.

RESULTS

Of 187 reviews identified in the search, 19 were included, comprising 205 unique trials. Four meta-analyses on the effects of booster sessions, behaviour change techniques, goal setting and motivational interventions showed a significantly small overall effect (SMD 0.24, 95% CI 0.13, 0.34) and no statistical heterogeneity (I2 = 0%) in the panoramic meta-analysis. Narrative synthesis revealed substantial clinical and methodological diversity. In total, the certainty of evidence is low regarding the efficacy of the investigated interventions and techniques on adherence, due to various methodological flaws. Most of the RCTs that were included in the reviews analysed cognitive and behavioural interventions in patients with musculoskeletal diseases, indicating moderate evidence for the efficacy of some techniques, particularly, booster sessions, supervision and graded exercise. The reviews provided less evidence for the efficacy of educational and psychosocial interventions and partly inconsistent findings. Most of the available evidence refers to short to medium-term efficacy. The combination of a higher number of behaviour change techniques was more efficacious.

CONCLUSIONS

The overview of reviews synthesised various potentially efficacious techniques that may be combined for a holistic and patient-centred approach and may support tailoring complex interventions to the patient's needs and dispositions. It also identifies various research gaps and calls for a more holistic approach to define and measure adherence in physiotherapy.

Telehealth Education in Allied Health Care and Nursing: Web-Based Cross-Sectional Survey of Students' Perceived Knowledge, Skills, Attitudes, and Experience

BACKGROUND

The COVID-19 pandemic has highlighted the growing relevance of telehealth in health care. Assessing health care and nursing students' telehealth competencies is crucial for its successful integration into education and practice.

OBJECTIVE

We aimed to assess students' perceived telehealth knowledge, skills, attitudes, and experiences. In addition, we aimed to examine students' preferences for telehealth content and teaching methods within their curricula.

METHODS

We conducted a cross-sectional web-based study in May 2022. A project-specific questionnaire, developed and refined through iterative feedback and face-validity testing, addressed topics such as demographics, personal perceptions, and professional experience with telehealth and solicited input on potential telehealth course content. Statistical analyses were conducted on surveys with at least a 50% completion rate, including descriptive statistics of categorical variables, graphical representation of results, and Kruskal Wallis tests for central tendencies in subgroup analyses.

RESULTS

A total of 261 students from 7 bachelor's and 4 master's health care and nursing programs participated in the study. Most students expressed interest in telehealth (180/261, 69% very or rather interested) and recognized its importance in their education (215/261, 82.4% very or rather important). However, most participants reported limited knowledge of telehealth applications concerning their profession (only 7/261, 2.7% stated profound knowledge) and limited active telehealth experience with various telehealth applications (between 18/261, 6.9% and 63/261, 24.1%). Statistically significant differences were found between study programs regarding telehealth interest (P=.005), knowledge (P<.001), perceived importance in education (P<.001), and perceived relevance after the pandemic (P=.004). Practical training with devices, software, and apps and telehealth case examples with various patient groups were perceived as most important for integration in future curricula. Most students preferred both interdisciplinary and program-specific courses.

CONCLUSIONS

This study emphasizes the need to integrate telehealth into health care education curricula, as students state positive telehealth attitudes but seem to be not adequately prepared for its implementation. To optimally prepare future health professionals for the increasing role of telehealth in practice, the results of this study can be considered when designing telehealth curricula.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Effectiveness of strategies to improve adherence to physical therapy in patients with knee and hip osteoarthritis: a systematic review and meta-analysis

PURPOSE

To determine the effectiveness of current strategies oriented to increase adherence to physical therapy in subjects with knee and hip osteoarthritis (OA).

MATERIAL AND METHODS

A systematic review of electronic databases was conducted from inception until March 2023. Studies with experimental interventions using strategies to increase adherence to physical therapy programs in subjects with knee or hip OA were included. A meta-analysis compared the effects of such interventions with usual care for adherence-related measures (primary outcome), and functional and pain outcomes, using standardized mean differences (SMD) with a 95% confidence interval (CI). GRADE was used to determine the strength of the resultant evidence and the external validity of the findings.

RESULTS

Fifteen articles, assessing 1,818 participants, were included. The interventions included cognitive-behavior strategies, telephone calls, internet-based interventions, communication technologies, and booster sessions. A meta-analysis revealed that the experimental interventions increased adherence over usual care with a moderate effect size of SMD = 0.39 (95%CI = 0.08-0.71) and moderate certainty in this evidence.

CONCLUSION

Overall, this review supports that the strategies to promote adherence to physical therapy in individuals with knee and hip OA are effective. However, the positive impact on adherence rates does not always translate into improved clinical outcomes.

Development of the INpaTiEnt Rehabilitation App Compliance QuesTionnaire [INTERACT]

BACKGROUND

The elements of previously designed questionnaires do not take into consideration the burdens encountered in an inpatient hospital setting. The purpose of this study is to validate elements of a non-compliance survey in an in-hospital setting and discuss aspects of compliance with telerehabilitative physiotherapy in the early postoperative period.

METHODS

A literature search was conducted to identify elements that prevent patients from performing their prescribed physical therapy exercises. These items were then evaluated by the expert review technique as described by Ikart. Afterwards, the synthesized survey was handed out to patients for the assessment of the quality of its items.

RESULTS

The results of the expert review technique identified some conceptual and grammatical problems. This led to the adjustment of some of the elements. The quality of the resulting questionnaire was deemed to be good, as patients were able to fully understand the concepts and answer accordingly. A statistical analysis was conducted to evaluate the responses.

CONCLUSIONS

The items of this second questionnaire have proven to be reliable to assess the compliance of patients in an in-hospital setting. These items will be added to the cross-culturally adapted items of a previous questionnaire.

Exercise therapy for tendinopathy: a mixed-methods evidence synthesis exploring feasibility, acceptability and effectiveness

Background

Tendinopathy is a common, painful and functionally limiting condition, primarily managed conservatively using exercise therapy.

Review questions

(i) What exercise interventions have been reported in the literature for which tendinopathies? (ii) What outcomes have been reported in studies investigating exercise interventions for tendinopathy? (iii) Which exercise interventions are most effective across all tendinopathies? (iv) Does type/location of tendinopathy or other specific covariates affect which are the most effective exercise therapies? (v) How feasible and acceptable are exercise interventions for tendinopathies?

Methods

A scoping review mapped exercise interventions for tendinopathies and outcomes reported to date (questions i and ii). Thereafter, two contingent systematic review workstreams were conducted. The first investigated a large number of studies and was split into three efficacy reviews that quantified and compared efficacy across different interventions (question iii), and investigated the influence of a range of potential moderators (question iv). The second was a convergent segregated mixed-method review (question v). Searches for studies published from 1998 were conducted in library databases (n = 9), trial registries (n = 6), grey literature databases (n = 5) and Google Scholar. Scoping review searches were completed on 28 April 2020 with efficacy and mixed-method search updates conducted on 19 January 2021 and 29 March 2021.

Results

Scoping review - 555 included studies identified a range of exercise interventions and outcomes across a range of tendinopathies, most commonly Achilles, patellar, lateral elbow and rotator cuff-related shoulder pain. Strengthening exercise was most common, with flexibility exercise used primarily in the upper limb. Disability was the most common outcome measured in Achilles, patellar and rotator cuff-related shoulder pain; physical function capacity was most common in lateral elbow tendinopathy. Efficacy reviews - 204 studies provided evidence that exercise therapy is safe and beneficial, and that patients are generally satisfied with treatment outcome and perceive the improvement to be substantial. In the context of generally low and very low-quality evidence, results identified that: (1) the shoulder may benefit more from flexibility (effect sizeResistance:Flexibility = 0.18 [95% CrI 0.07 to 0.29]) and proprioception (effect sizeResistance:Proprioception = 0.16 [95% CrI -1.8 to 0.32]); (2) when performing strengthening exercise it may be most beneficial to combine concentric and eccentric modes (effect sizeEccentricOnly:Concentric+Eccentric = 0.48 [95% CrI -0.13 to 1.1]; and (3) exercise may be most beneficial when combined with another conservative modality (e.g. injection or electro-therapy increasing effect size by ≈0.1 to 0.3). Mixed-method review - 94 studies (11 qualitative) provided evidence that exercise interventions for tendinopathy can largely be considered feasible and acceptable, and that several important factors should be considered when prescribing exercise for tendinopathy, including an awareness of potential barriers to and facilitators of engaging with exercise, patients' and providers' prior experience and beliefs, and the importance of patient education, self-management and the patient-healthcare professional relationship.

Limitations

Despite a large body of literature on exercise for tendinopathy, there are methodological and reporting limitations that influenced the recommendations that could be made.

Conclusion

The findings provide some support for the use of exercise combined with another conservative modality; flexibility and proprioception exercise for the shoulder; and a combination of eccentric and concentric strengthening exercise across tendinopathies. However, the findings must be interpreted within the context of the quality of the available evidence.

Future work

There is an urgent need for high-quality efficacy, effectiveness, cost-effectiveness and qualitative research that is adequately reported, using common terminology, definitions and outcomes.

Factors Associated With Adherence to a Supervised Exercise Intervention for Osteoarthritis: Data From the Swedish Osteoarthritis Registry

OBJECTIVE

To explore how lifestyle and demographic, socioeconomic, and disease-related factors are associated with supervised exercise adherence in an osteoarthritis (OA) management program and the ability of these factors to explain exercise adherence.

METHODS

A cohort register-based study on participants from the Swedish Osteoarthritis Registry who attended the exercise part of a nationwide Swedish OA management program. We ran a multinomial logistic regression to determine the association of exercise adherence with the abovementioned factors. We calculated their ability to explain exercise adherence with the McFadden R2 .

RESULTS

Our sample comprises 19,750 participants (73% female, mean ± SD age 67 ± 8.9 years). Among them, 5,862 (30%) reached a low level of adherence, 3,947 (20%) a medium level, and 9,941 (50%) a high level. After a listwise deletion, the analysis was run on 16,685 participants (85%), with low levels of adherence as the reference category. Some factors were positively associated with high levels of adherence, such as older age (relative risk ratio [RRR] 1.01 [95% confidence interval (95% CI) 1.01-1.02] per year), and the arthritis-specific self-efficacy (RRR 1.04 [95% CI 1.02-1.07] per 10-point increase). Others were negatively associated with high levels of adherence, such as female sex (RRR 0.82 [95% CI 0.75-0.89]), having a medium (RRR 0.89 [95% CI 0.81-0.98] or a high level of education (RRR 0.84 [95% CI 0.76-0.94]). Nevertheless, the investigating factors could explain 1% of the variability in exercise adherence (R2 = 0.012).

CONCLUSION

Despite the associations reported above, the poorly explained variability suggests that strategies based on lifestyle and demographic, socioeconomic, and disease-related factors are unlikely to improve exercise adherence significantly.

Rehabilitation interventions in osteoarthritis

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

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.

Association between adherence to a home exercise program and central sensitization, pain intensity, and functionality in individuals with knee osteoarthritis

Objective

To analyze the association between adherence to a home exercise program and central sensitization, pain intensity, and functionality in individuals with knee osteoarthritis (KOA).

Methods

A cross-sectional study was conducted involving 57 individuals with KOA. Evaluations were performed using the Exercise Adherence Rating Scale (EARS), the numerical rating scale (NRPS), the International Knee Documentation Committee (IKDC), The Central Sensitization Inventory (CSI), and the 30 sec sit and stand test (30SSST). Histograms were created to determine the normality of the data. The Kolmogorov-Smirnov test was used to determine the normality of the data. Thus, Pearson’s (r) and determination (R2) correlation coefficients were calculated to determine the strength of associations between variables.

Results

No significant association was found between adherence behavior or reasons for adherence and central sensitization symptoms, the intensity of pain on rest and movement, knee disability symptoms, and functionality.

Conclusion

No significant association was identified between adherence to a home exercise program and central sensitization, pain intensity, and functionality in individuals with KOA.

The Effectiveness of Manual Therapy in the Cervical Spine and Diaphragm, in Combination with Breathing Reeducation Exercises, in Patients with Non-Specific Chronic Neck Pain: Protocol for Development of Outcome Measures and a Randomized Controlled Trial

Until now, non-specific chronic neck pain has mainly been considered as a musculoskeletal system dysfunction, with associated psychological involvement due to its prolonged or recurrent nature. However, patients with non-specific chronic neck pain frequently additionally exhibit respiratory dysfunction. Emerging evidence suggests that addressing the respiratory dysfunction in these patients will provide additional therapeutic benefits in musculoskeletal and respiratory-related outcomes for several reasons (biomechanical, biochemical, and psychological). Motor control dysfunction of the muscles surrounding the spine (diaphragm included) negatively affects the mechanics and biochemistry of breathing (pH-homeostasis). An impaired and ineffective breathing pattern has been recognized as the primary source of many unexplained symptoms (anxiety, depression, confusion, chest pain, hypocapnia, and breathlessness) in patients with non-specific chronic neck pain. The proposed protocol’s purpose is dual: to assess the relative effectiveness of manual therapy in the cervical spine and the diaphragm, in combination with breathing reeducation exercises, along with cervical spine manual therapy or usual physical therapy care on the underlying dysfunctions in patients with non-specific chronic neck pain via a randomized controlled clinical trial, and to validate part of the outcome measures. Several musculoskeletal and respiratory dysfunction outcomes will be employed to delimit the initial extent and level of dysfunction and its resolution with the treatments under study.
