The Effectiveness of Virtual Reality Rehabilitation in Patients with Knee and Hip Osteoarthritis

Immersive and Nonimmersive Virtual Reality-Assisted Active Training in Chronic Musculoskeletal Pain: Systematic Review and Meta-Analysis

BACKGROUND

Virtual reality (VR) in different immersive conditions has been increasingly used as a nonpharmacological method for managing chronic musculoskeletal pain.

OBJECTIVE

We aimed to assess the effectiveness of VR-assisted active training versus conventional exercise or physiotherapy in chronic musculoskeletal pain and to analyze the effects of immersive versus nonimmersive VR on pain outcomes.

METHODS

This systematic review of randomized control trials (RCTs) searched PubMed, Scopus, and Web of Science databases from inception to June 9, 2024. RCTs comparing adults with chronic musculoskeletal pain receiving VR-assisted training were included. The primary outcome was pain intensity; secondary outcomes included functional disability and kinesiophobia. Available data were pooled in a meta-analysis. Studies were graded using the Cochrane Risk-of-Bias Tool version 2.

RESULTS

In total, 28 RCTs including 1114 participants with some concerns for a high risk of bias were identified, and 25 RCTs were included in the meta-analysis. In low back pain, short-term outcomes measured post intervention showed that nonimmersive VR is effective in reducing pain (standardized mean difference [SMD] -1.79, 95% CI -2.72 to -0.87; P<.001), improving disability (SMD -0.44, 95% CI -0.72 to -0.16; P=.002), and kinesiophobia (SMD -2.94, 95% CI -5.20 to -0.68; P=.01). Intermediate-term outcomes measured at 6 months also showed that nonimmersive VR is effective in reducing pain (SMD -8.15, 95% CI -15.29 to -1.01; P=.03), and kinesiophobia (SMD -4.28, 95% CI -8.12 to -0.44; P=.03) compared to conventional active training. For neck pain, immersive VR reduced pain intensity (SMD -0.55, 95% CI -1.02 to -0.08; P=.02) but not disability and kinesiophobia in the short term. No statistical significances were detected for knee pain or other pain regions at all time points. In addition, 2 (8%) studies had a high risk of bias.

CONCLUSIONS

Both nonimmersive and immersive VR-assisted active training is effective in reducing back and neck pain symptoms. Our study findings suggest that VR is effective in alleviating chronic musculoskeletal pain.

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.

Variation in Utilization of Postoperative Rehabilitation After Total Hip Arthroplasty in Japan

OBJECTIVE

The use of rehabilitation after arthroplasty in Japan is unknown. We aimed to identify utilization of postoperative rehabilitation after total hip arthroplasty (THA) and to explore the factors associated with rehabilitation usage.

DESIGN

A retrospective cohort study using the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB).

SETTING

Hospitals nationwide.

PARTICIPANTS

Patients aged >40 years who underwent primary THA between 2017 and 2018 (N=51,332).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The proportion of patients who underwent postoperative rehabilitation and the number of rehabilitation days were also calculated. Patient demographic characteristics, hospital case volumes, and regions associated with continuing postoperative rehabilitation were analyzed using a Cox proportional hazards model.

RESULTS

Eligible patients were selected from 3033 hospitals, of whom 41,192 (80%) were women. Of these, 94% used inpatient rehabilitation, and 20% received outpatient rehabilitation. The mean durations of rehabilitation were 47±72 days for inpatient and 195±109 days for outpatient, respectively. Large-scale hospitals performing more than 200 procedures annually had the shortest duration of inpatient rehabilitation (36-65 days) and the longest duration of outpatient rehabilitation (220-109 days) compared with smaller hospitals. The regression model consistently showed that rehabilitation continued longer at hospitals with over 200 patients per year (HR 0.96, 95% CI 0.93-0.99, P<.007).

CONCLUSION

The Japanese health care system provided higher access to inpatient rehabilitation after THA than other countries. One limitation of this study is that long-term care insurance data were not analyzed. However, outpatient rehabilitation vary according to hospital case volume. Further research is needed to determine the causes of variation in rehabilitation use and the effect of variation on patient outcomes.

Virtual Reality in Improving Anticipatory Postural Adjustments to Step Initiation in Individuals with Knee Osteoarthritis: A Randomized Controlled Trial

Background: Virtual reality (VR) has been suggested as a new therapeutic approach in various sectors of rehabilitation, including the treatment of patients with knee osteoarthritis (OA), and one of its treatment goals is to improve the gait pattern and walking ability of patients. Objective: This study aimed to evaluate if VR, along with conventional physiotherapy treatment (CT), has superior effects to kinesiotherapy alone on pain, physical capacity, balance, and the parameters of anticipatory postural adjustments (APAs) in patients with knee OA. Design: This study is a single-blind randomized controlled trial. Setting: Secondary care at Hospital SARAH Network of Rehabilitation Hospitals, Brazil. Participants: Forty participants (31 women and 9 men) with knee OA in at least one knee and able to ambulate independently. Intervention: A rehabilitation program (8 consecutive weeks, 50-minute session, twice a week). Patients were randomized into the intervention groups CT or VR. Main Outcome Measures: Primary-latency of APA, amplitude of APA, and time to reach the maximum acceleration amplitude. Secondary-balance control by Mini-Balance Evaluation Systems Test, pain, and physical capacity by Western Ontario and McMaster Universities Arthritis Index. Results: The results of the study showed that conventional treatment significantly improved pain intensity, physical capacity, and balance in individuals with knee OA; however, only the group that used VR showed improvement in the APA parameters. Conclusion: This study demonstrated that VR associated with conventional treatment improved APAs in patients with knee OA.

The Effectiveness of Virtual Reality, Augmented Reality, and Mixed Reality Rehabilitation in Total Knee Arthroplasty: A Systematic Review and Meta-Analysis

BACKGROUND

Extended reality (XR), including virtual reality, augmented reality, and mixed reality, has been increasingly used in postoperative rehabilitation of total knee arthroplasty (TKA). The purpose of this systematic review and meta-analysis was to evaluate the effectiveness of XR-based rehabilitation in TKA compared to conventional rehabilitation.

METHODS

In this study, we searched PubMed (MEDLINE), Embase (OVID), Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and clinicaltrials.gov from inception to February 15, 2023 for eligible studies. A total of 14 randomized controlled trials with 989 patients were included in our study. The primary outcomes were pain and function. The secondary outcomes were anxiety and quality of life. A systematic review and meta-analysis was performed.

RESULTS

The pooled data indicated XR-based rehabilitation significantly improved the visual analog scale (standardized mean difference [SMD] = -0.31, 95% Confidence Interval [CI] [-0.47 to -0.15], P = .0001), the Western Ontario and McMaster Universities Osteoarthritis Index (SMD = -0.46, 95% CI [-0.86 to -0.06], P = .02), range of motion (SMD = 0.40, 95% CI [0.09 to 0.72], P = .01), and anxiety scores (mean difference = -3.95, 95% CI [-7.76 to -0.13], P = .04) than conventional rehabilitation, but Timed Up and Go test and quality of life were similar in the 2 groups.

CONCLUSION

This systematic review and meta-analysis found XR-based rehabilitation improved pain, function, and anxiety, but not quality of life in TKA compared to conventional rehabilitation within 1 month postoperatively. Based on the pooled results, we suggested that XR-based rehabilitation may have benefit in patients' postoperative rehabilitation in TKA.

Effectiveness of Virtual Reality-Based Rehabilitation Interventions in Improving Postoperative Outcomes for Orthopedic Surgery Patients

PURPOSE OF REVIEW

The surge in orthopedic surgeries strains the US healthcare system, necessitating innovative rehabilitation solutions. This review examines the potential of virtual reality (VR)-based interventions for orthopedic rehabilitation.

RECENT FINDINGS

The effectiveness of VR-based interventions in orthopedic surgery patients is scrutinized. While some studies suggest better patient-reported outcomes and satisfaction, mixed results emerge from others, demonstrating comparable or varied results compared to traditional rehabilitation. The underlying mechanisms of VR-based rehabilitation are elucidated, showing its positive impact on proprioception, pain management, agency, and balance. Challenges of unfamiliarity, patient engagement, and drop-out rates are identified, emphasizing the need for tailored approaches. VR technology's immersive environments and multisensory experiences offer a novel approach to addressing functional deficits and pain post-surgery. The conclusion drawn is that VR-based rehabilitation complements rather than replaces conventional methods, potentially aiding in pain reduction and functional improvement. VR-based rehabilitation holds promise for enhancing orthopedic surgery outcomes, presenting a dynamic approach to recovery. Its potential to reshape healthcare delivery and reimbursement structures underscores its significance in modern healthcare. Overall, VR-based rehabilitation offers a promising avenue for optimizing postoperative recovery in orthopedic surgery patients.

Experiences of physiotherapists considering virtual reality for shoulder rehabilitation: A focus group study

Introduction

Shoulder pain is common and associated with substantial morbidity. Different treatment strategies are being prescribed with equivocal results. Virtual reality (VR) is a novel technology and emerging research suggests that VR may be a promising alternative to current treatments. Prior to effectiveness research or any large-scale introduction, VR-applications require appropriate scrutiny including feasibility- and acceptability of clinicians and patients. Therefore, the aim of this study was to collect experiences of physiotherapists after using immersive VR.

Methods

A qualitative interpretive design was used to explore physiotherapists' experiences related to the use of VR for people with shoulder symptoms. 17 physiotherapists were asked to use VR at home for five days prior to a focus group interview. Data from the focus group interviews were analyzed using a six-phase process of thematic analysis.

Results

Three main themes were identified, each divided into subthemes. The main themes were: 1. VR as an extension of contemporary physiotherapy care: physiotherapists were positive about the potential of VR and its applicability in daily care. 2. Physiotherapist uncertainties of future care using VR: participants expressed concerns about their professional identity, particularly as patients engage in independent home exercises. 3. Physiotherapist's requirements for implementation of VR: participants shared their needs for evidence regarding the effectiveness and parameters such as frequency, dosage and intensity of the VR intervention.

Conclusion

Physiotherapists were positive about VR as an intervention tool. However, they felt more knowledge is needed about parameters of VR. The findings of this study inform researchers and technology developers about optimal design of interventions and applications using VR.

Effects of Electromyographic Biofeedback-Assisted Exercise on Functional Recovery and Quality of Life in Patients after Total Hip Arthroplasty: A Randomized Controlled Trial

The goal of the trial was to examine the effects of adding electromyographic biofeedback (EMG-BF) to the conventional program of physiotherapy after total hip arthroplasty (THA) on functional recovery and quality of life. The trial was designed as a prospective, interventional, single-blinded randomized controlled study. Ninety patients were randomized into an experimental group (EG) (n = 45; mean age 63.9 ± 8.8) and control group (CG) (n = 45; mean age 63.9 ± 9). All patients received 21 days of physiotherapy which consisted of therapeutic exercise (land-based and aquatic), electrotherapy, and education. Electromyographic biofeedback was added to a portion of the land-based exercise in EG. The Hip Disability and Osteoarthritis Outcome Score (HOOS), Numeric Rating Scale (NRS), Short Form Health Survey-36 (SF-36), use of a walking aid, 30 s chair stand test (CST) as well as the Timed Up and Go (TUG) test were used for outcome measurement. A higher proportion of the participants in both groups did not need a walking aid after the intervention (p < 0.05). All participants improved their 30 s CST and TUG results (p < 0.001), as well as their NRS and HOOS scores (p < 0.05). No significant differences between the groups were found. There were no additional benefits from adding EMG-BF to the conventional physiotherapy protocol.

Effectiveness of a digital rehabilitation program based on computer vision and augmented reality for isolated meniscus injury: protocol for a prospective randomized controlled trial

BACKGROUND

The lack of access to physical therapists in developing countries and rural areas poses a significant challenge in supervising postsurgical rehabilitation, potentially impeding desirable outcomes following surgical interventions. For this reason, this study aims to evaluate the feasibility, safety, and effectiveness of utilizing a digital rehabilitation program based on computer vision and augmented reality in comparison with traditional care for patients who will undergo isolated meniscus repair, since to date, there is no literature on this topic.

METHODS

This study intends to enroll two groups of participants, each to be provided with informed consent before undergoing randomization into either the experimental or control group. The experimental group will undergo a digital rehabilitation program utilizing computer vision and augmented reality (AR) technology following their surgical procedure, while the control group will receive conventional care, involving in-clinic physical therapy sessions weekly. Both groups will adhere to a standardized rehabilitation protocol over a six-month duration. Follow-up assessments will be conducted at various intervals, including preoperatively, and at 2 weeks, 6 weeks, 12 weeks, and 24 weeks postoperatively. Imaging assessments and return-to-play evaluations will be conducted during the final follow-up. Clinical functionality will be assessed based on improvements in International Knee Documentation Committee (IKDC) and Visual Analog Scale (VAS) scores.

Multidisciplinary Rehabilitation after Hyaluronic Acid Injections for Elderly with Knee, Hip, Shoulder, and Temporomandibular Joint Osteoarthritis

Osteoarthritis (OA) is a prevalent degenerative joint condition characterized by cartilage deterioration, joint inflammation, and functional limitations, particularly impacting the elderly population. Rehabilitation and hyaluronic acid (HA) injections are common therapeutic approaches routinely used in clinical practice, but their synergistic potential is far from being fully characterized. Thus, the aim of this narrative review was to elucidate the multilevel benefits and synergies of integrating these two approaches in multidisciplinary OA rehabilitation. This narrative review follows the scale for the assessment of narrative review articles (SANRA) criteria and involves a comprehensive literature search from July to August 2023. Two independent reviewers screened studies, including those involving human subjects with OA, rehabilitation strategies, and outcomes following HA injection, published in English. Results: HA injections might improve joint biomechanics, reducing friction, absorbing shocks, and potentially regulating inflammation. Rehabilitation plays a pivotal role in strengthening muscles, increasing the range of motion, and enhancing overall function. Optimizing rehabilitation following HA injection might provide additional benefits in joint health. OA management requires a multidisciplinary approach integrating HA injections, rehabilitation, and personalized care. Challenges in patient adherence and healthcare resources currently exist, but emerging technologies offer opportunities to enhance patient engagement and monitoring optimizing sustainability and outcomes of patients with knee, hip, shoulder, and temporomandibular joint OA.

The Role of Neutrophil to Lymphocyte Ratio in the Assessment and Rehabilitation of Knee Osteoarthritis Patients

Osteoarthritis (OA) is considered to be a real problem for many people. The last decade is characterized through an increased interest in using a non-specific, simply and readily available marker of inflammation-neutrophil to lymphocyte ratio (NLR)-to predict various chronic diseases (gastrointestinal and colorectal cancers, lung cancer, cardiovascular events, sarcoidosis, arthritis). The aim of our study is to establish the correlation between NLR and other parameters of clinical and functional status in KOA patients and to compare the NLR values before and after rehabilitation program. 90 patients, aged 40 to 82 years, diagnosed with mild (8 patients), moderate (70 patients) and severe (12 patients) KOA, in accordance with Kellgren and Lawrence score. Statistical assessment showed different values for the erythrocyte sedimentation (ESR) rate at 1-hour, Visual Analogue Scale (VAS), and Lequesne index in the studied group. NLR regression was significant for ESR at 1 and 2 hours. As an independent diagnostic marker, NLR has limited value, however it can be considered an inexpensive additional biomarker for the diagnosis of KOA and for monitoring the rehabilitation program.

Wearable rehabilitation wristband for distal radius fractures

Background

Distal radius fractures are a common type of fracture. For patients treated with closed reduction with splinting, a period of rehabilitation is still required after the removal of the splint. However, there is a general lack of attention and low compliance to rehabilitation training during this period, so it is necessary to build a rehabilitation training monitoring system to improve the efficiency of patients' rehabilitation.

Methods

A wearable rehabilitation training wristband was proposed, which could be used in the patient's daily rehabilitation training scenario and could recognize four common wrist rehabilitation actions in real-time by using three thin film pressure sensors to detect the pressure change curve at three points on the wrist. An algorithmic framework for classifying rehabilitation training actions was proposed. In our framework, an action pre-detection strategy was designed to exclude false detections caused by switching initial gestures during rehabilitation training and wait for the arrival of the complete signal. To classify the action signals into four categories, firstly an autoencoder was used to downscale the original signal. Six SVMs were then used for evaluation and voting, and the final action with the highest number of votes would be used as the prediction result.

Results

Experimental results showed that the proposed algorithmic framework achieved an average recognition accuracy of 89.62%, an average recognition recall of 88.93%, and an f1 score of 89.27% on the four rehabilitation training actions.

Conclusion

The developed device has the advantages of being small size and easy to wear, which can quickly and accurately identify and classify four common rehabilitation training actions. It can easily be combined with peripheral devices and technologies (e.g., cell phones, computers, Internet) to build different rehabilitation training scenarios, making it worthwhile to use and promote in clinical settings.

The Effect of a Virtual Reality-Mediated Gamified Rehabilitation Program on Pain, Disability, Function, and Balance in Knee Osteoarthritis: A Prospective Randomized Controlled Study

Background: This prospective randomized controlled study is the first study that evaluates the disease-specific gamification through virtual reality (VR) glasses on pain, disability, functionality, and balance in knee osteoarthritis (OA). Materials and Methods: The demographic data of the patients were recorded. A total of 73 patients were divided into two groups (35 in experimental group and 38 in control group). All patients were evaluated with pain (visual analog scale [VAS]), functionality (Lysholm functional knee score [LFKS], 6 minutes walking test [6MWT]), disability (Western Ontario and McMaster Universities Arthritis Index [WOMAC]), and balance (Berg Balance Scale [BBS]) before treatment, after treatment (3th weeks), and 4 weeks after treatment (7th weeks). In the experimental group, plus the conservative treatment, a total of 15 sessions of a disease-specific gamification through VR glasses were applied. Results: VAS and WOMAC scores of the experimental group were lower at the 3th and 7th weeks than those of the control group (P = 0.005, P = 0.000), (P = 0.000). LFKS of the experimental group was higher at the 3th and 7th weeks than that of the control group (P = 0.005, P = 0.013). No difference was found between the groups in terms of 6MWTs (P > 0.05). BBS score of the experimental group was higher in the 7th week than that of the control group (P = 0.021). Conclusion: In knee OA, the disease-specific gamification through VR glasses added to the conservative treatment has a positive effect on pain, functionality, and balance. Side effects such as mild nausea, headache that did not last long, require additional treatment. In light of this, disease-specific gamification through VR glasses is effective and safe in knee OA, more studies that reveal the long-term effect on structural healing must be planned.

Technical aspects of virtual augmented reality-based rehabilitation systems for musculoskeletal disorders of the lower limbs: a systematic review

INTRODUCTION

Musculoskeletal disorders are one of the most common causes of physical disability. The rehabilitation process after musculoskeletal disorders is long and tedious, and patients are not motivated to follow rehabilitation protocols. Therefore, new systems must be used to increase patient motivation. Virtual reality (VR) and augmented reality (AR) technologies can be used in this regard. In developing such systems, various technologies and methods of movement recognition are used; therefore, this study aims to summarize the technical aspects of using VR/AR in rehabilitation and evaluate and discuss efficient methods of investigating studies using the Statement of Standards for Reporting Implementation Studies (StaRI).

METHODS

Search in four scientific databases was done systematically based on PRISMA through online search engines from inception to June 2021. These databases include Medline (PubMed), Scopus, IEEE, and Web of Science. An updated search was also conducted on 17 December 2021. The research used keywords and MeSH terms associated with VR/AR, musculoskeletal disorder, and rehabilitation. Selected articles were evaluated qualitatively using the Standards for Reporting Implementation Studies (StaRI) statement.

RESULTS

A total of 2343 articles were found, and 20 studies were included. We found that 11 (55%) studies used Kinect technology as input tools, and 15 (75%) studies have described the techniques used to analyze human movements, such as dynamic time warping (DTW) and support vector machines (SVM). In 10 (50%) studies, the Unity game engine was used for visualization. In 8 studies (40%), usability was assessed, and high usability was reported. Similarly, the results of the review of studies according to the StaRI checklist showed poor reporting in the title and discussion of the studies.

CONCLUSIONS

We found that academic studies did not describe the technical aspects of rehabilitation systems. Therefore, a good description of the technical aspects of the system in such studies should be considered to provide repeatability and generalizability of these systems for investigations by other researchers.

180-degree immersive VR motion visualization in the treatment of haemophilic ankle arthropathy

BACKGROUND

Patients with haemophilic arthropathy suffer chronic pain that affects and restricts their quality of life. Visualization of movement through immersive virtual reality is used for pain management.

AIM

To evaluate the efficacy of 180-degree immersive VR motion visualization therapy in patients with haemophilic ankle arthropathy.

METHODS

Prospective, multicentre pilot study. Fifteen adult patients with bilateral haemophilic ankle arthropathy were recruited (mean age: 42.73 ± 12.36 years). The intervention lasted 4 weeks, with daily home sessions of 180-degree immersive motion visualization. The patients were given virtual reality glasses to use with their smartphones. From the YouTube mobile app® they accessed the recorded video with access from the He-Mirror App®. The study variables were joint state (Haemophilia Joint Health Score), pressure pain threshold (pressure algometer), muscle strength (dynamometry) and range of motion (goniometry). Three evaluations were performed: at baseline (T0), after the intervention (T1) and at the end of a 16-week follow-up period (T2).

RESULTS

No patient developed ankle hemarthrosis during the experimental phase. In the repeated measures analysis we found statistically significant differences in joint state (F = 51.38; η² _p = .63), pressure pain threshold of the lateral malleolus (F = 12.34; η² _p = .29) and range of motion (F = 11.7; η² _p = .28).

CONCLUSIONS

Therapy using immersive motion visualization does not cause hemarthrosis. This intervention can improve joint condition, pressure pain threshold and range of motion in patients with ankle arthropathy. Changes greater than the MDC were reported in more than 40% of patients for the variables pressure pain threshold, anterior tibialis strength and range of motion, which were considered clinically relevant.

Methodological Quality of Physical Therapy-Related Trials Published in Open Access and Subscription Journal: A Cross-sectional Meta-Epidemiological Study

OBJECTIVE

We aimed to compare the methodological quality of physical therapy-related trials published in open access with that of trials published in subscription-based journals, adjusting for subdiscipline, intervention type, endorsement of the Consolidated Standards of Reporting Trials, impact factor, and publication language.

DESIGN

In this meta-epidemiological study, we searched the Physiotherapy Evidence Database on May 8, 2021, to include any physical therapy-related trials published from January 1, 2020. We extracted variables such as Consolidated Standards of Reporting Trials endorsement, the Physiotherapy Evidence Database score, and publication type. We compared the Physiotherapy Evidence Database score between the publication types using a multivariable generalized estimating equation by adjusting for covariates.

RESULTS

A total of 2743 trials were included, with a mean total Physiotherapy Evidence Database score (standard deviation) of 5.8 (±1.5). Trials from open access journals had a lower total Physiotherapy Evidence Database score than those from subscription-based journals (5.5 ± 1.5 vs. 5.9 ± 1.5, mean difference = -0.4; 95% confidence interval = 0.3-0.5). Generalized estimating equation revealed that open access publication was significantly associated with the total Physiotherapy Evidence Database score (mean difference = -0.42; P < 0.001).

CONCLUSIONS

In the recent physical therapy-related trials, open access publications demonstrated lower methodological quality than subscription-based publications, although with a small difference.

Assessment Tools of Biopsychosocial Frailty Dimensions in Community-Dwelling Older Adults: A Narrative Review

Frailty is a complex interplay between several factors, including physiological changes in ageing, multimorbidities, malnutrition, living environment, genetics, and lifestyle. Early screening for frailty risk factors in community-dwelling older people allows for preventive interventions on the clinical and social determinants of frailty, which allows adverse events to be avoided. By conducting a narrative review of the literature employing the International Narrative Systematic Assessment tool, the authors aimed to develop an updated framework for the main measurement tools to assess frailty risks in older adults, paying attention to use in the community and primary care settings. This search focused on the biopsychosocial domains of frailty that are covered in the SUNFRAIL tool. The study selected 178 reviews (polypharmacy: 20; nutrition: 13; physical activity: 74; medical visits: 0; falls: 39; cognitive decline: 12; loneliness: 15; social support: 5; economic constraints: 0) published between January 2010 and December 2021. Within the selected reviews, 123 assessment tools were identified (polypharmacy: 15; nutrition: 15; physical activity: 25; medical visits: 0; falls: 26; cognitive decline: 18; loneliness: 9; social support: 15; economic constraints: 0). The narrative review allowed us to evaluate assessment tools of frailty domains to be adopted for multidimensional health promotion and prevention interventions in community and primary care.

Effect of balance training using virtual reality-based serious games in individuals with total knee replacement: A randomized controlled trial

BACKGROUND

Virtual reality (VR) and serious games (SGs) are widespread in rehabilitation for many orthopedic and neurological diseases. However, few studies have addressed the effects of rehabilitation with VR-based SGs on clinical, gait, and postural outcomes in individuals with total knee replacement (TKR).

OBJECTIVE

The primary objective was the efficacy of balance training using non-immersive VR-based SGs compared to conventional therapy in TKR patients on the Time Up and Go test. Secondary objectives included the efficacy on clinical, gait, and postural outcomes.

METHODS

We randomly allocated 56 individuals with unilateral TKR to the experimental group (EG) or control group (CG) for 15 sessions (45 min; 5 times per week) of non-immersive VR-based SGs or conventional balance training, respectively. The primary outcome was functional mobility measured by the Timed Up and Go test; secondary outcomes were walking speed, pain intensity, lower-limb muscular strength, independence in activities of daily living as well as gait and postural parameters.

RESULTS

We found significant within-group differences in all clinical outcomes and in a subset of gait (p<0.0001) and postural (p ≤ 0.05) parameters. Analysis of the stance time of the affected limb revealed significant between-group differences (p = 0.022): post-hoc analysis revealed within-group differences in the EG (p = 0.002) but not CG (p = 0.834). We found no significant between-group differences in other outcomes.

CONCLUSIONS

Balance training with non-immersive VR-based SGs can improve clinical, gait, and postural outcomes in TKR patients. It was not superior to the CG findings but could be considered an alternative to the conventional approach and can be added to a regular rehabilitation program in TKR patients. The EG had a more physiological duration of the gait stance phase at the end of the treatment than the CG.

Approach to Knee Arthropathy through 180-Degree Immersive VR Movement Visualization in Adult Patients with Severe Hemophilia: A Pilot Study

(1) Background: Hemarthrosis is a typical clinical manifestation in patients with hemophilia. Its recurrence causes hemophilic arthropathy, characterized by chronic joint pain. Watching movement recorded from a first-person perspective and immersively can be effective in the management of chronic pain. The objective of this study was to evaluate the effectiveness of an immersive virtual reality intervention in improving the pain intensity, joint condition, muscle strength and range of motion in patients with hemophilic knee arthropathy. (2) Methods: Thirteen patients with hemophilic knee arthropathy were recruited. The patients wore virtual reality glasses and watched a flexion-extension movement of the knee on an immersive 180° video, recorded from a first-person perspective over a 28-day period. The primary variable was the pain intensity (visual analog scale). The secondary variables were the joint status (Hemophilia Joint Health Score), quadriceps and hamstring strength (dynamometry), and range of motion (goniometry). (3) Results: After the intervention period, statistically significant differences were observed in the intensity of the joint pain (Standard error [SE] = 19.31; 95% interval confidence [95%CI] = -1.05; -0.26), joint condition (SE = 18.68; 95%CI = -1.16; -0.52) and quadriceps strength (SE = 35.00; 95%CI = 2.53; 17.47). We found that 38.46% and 23.07% of the patients exhibited an improvement in their quadriceps muscle strength and joint condition above the minimum detectable change for both variables (8.21% and 1.79%, respectively). (4) Conclusions: One hundred and eighty degree immersive VR motion visualization can improve the intensity of joint pain in patients with hemophilic knee arthropathy. An intervention using immersive virtual reality can be an effective complementary approach to improve the joint condition and quadriceps strength in these patients.

Telemedicine Technologies Selection for the Posthospital Patient Care Process after Total Hip Arthroplasty

For many years, the importance of using telematic technologies in medicine has been growing, especially in the period of the coronavirus pandemic, when direct contact and supervision of medical personnel over the patient is difficult. The existing possibilities of modern information and communication technologies (ICTs) are not fully used. The aim of the study is to identify the telemedicine technologies that can be used in future implementation projects of the posthospital patient care process after total hip arthroplasty (THA). The literature search is reported according to PRISMA 2020. The search strategy included databases and gray literature. In total, 28 articles (EMBASE, PubMed, PEDro) and 24 records from gray literature (Google Search and Technology presentations) were included in the research. This multi-source study analyzes the possibilities of using different technologies useful in the patient care process. The conducted research resulted in defining visual and wearable types of telemedicine technologies for the original posthospital patient care process after THA. As the needs of stakeholders in the posthospital patient care process after THA differ, the awareness of appropriate technologies selection, information flow, and its management importance are prerequisites for effective posthospital patient care with the use of telemedicine technologies.

Effectiveness of Early Rehabilitation with Exergaming in Virtual Reality on Gait in Patients after Total Knee Replacement

Total knee replacement (TKR) is the treatment of choice for advanced stages of osteoarthritis but it requires good postoperative rehabilitation. This study aimed to assess the effectiveness of exercises using virtual reality to improve gait parameters in patients after TKR. Fifty-nine patients 7−14 days after TKR surgery were divided into a study group (VRG, n = 38) and a control group (CG, n = 21). Both groups underwent the same 4-week rehabilitation protocol. The VRG group had 12 additional nonimmersive virtual reality game sessions on the Virtual Balance Clinic prototype system at 30 min each, focusing on gait and balance improvement. Spatiotemporal, force and foot plantar pressure parameters were collected on an instrumented treadmill during a 30 s walk. The most significant improvement was in the symmetry indices of forefoot force, maximum forefoot force, loading response time, and preswing time (p < 0.05) in both groups. Gait speed increased by 31.25% and 44% in the VRG and CG groups, respectively (p < 0.005). However, the extra exergaming sessions did not significantly improve rehabilitation outcomes. Therefore, additional VR training does not improve gait better than standard rehabilitation alone, but the improvement of gait, especially its symmetry, is significant within the first six weeks after surgery.

The Feasibility and Effectiveness of Virtual Reality Meditation on Reducing Chronic Pain for Older Adults with Knee Osteoarthritis

There is an urgent need for safe and effective non-pharmacologic approaches to treat chronic knee pain in older adults. Although virtual reality (VR) has shown some effectiveness for acute pain, there is limited evidence on the effects of VR on chronic pain particularly with older adult populations. This single application, within-subject pilot study evaluated the feasibility and effectiveness of VR as a clinical treatment for older adults with chronic osteoarthritis knee pain. Nineteen participants aged 60+ years old participated in a 10-minute VR meditation program. Data on pain and affect were collected immediately prior to, post, and 24-48 hours after the VR. Results suggest that VR meditation had significant moderate-large analgesic effects on knee pain intensity, primarily during VR (d = 1.10) and post VR (d = .99), with some lasting effects into next day (d = .58). The findings also suggest VR meditation intervention had a positive effect on affect, with a significant large decrease in negative affect scores pre to post VR (d = 1.14). The significant moderate to large decreases in pain interference for normal work (d = .71), mood (d = .53), sleep (d = .67), and enjoyment of life (d = .72) suggest that older adults may have a higher ability to participate in meaningful daily activities up to 24-48 hours after VR meditation. VR appears to be a feasible and effective nonpharmacological tool for older adults to treat chronic overall & knee-specific pain.

Exergames to Improve Rehabilitation for Shoulder Injury: Systematic Review and GRADE Evidence Synthesis

INTRODUCTION

The use of exergames has become an increasingly frequent intervention in rehabilitation, referred to as a fun and motivating activity that involves patients. This systematic review aimed to evaluate the effectiveness of exergames in the rehabilitation of the shoulder joint compared to other types of care.

METHODS

We performed a systematic review and GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) evidence synthesis. The search was conducted using the following databases: MEDLINE, CINAHL, SPORTDiscus, SCOPUS, SciELO, Psychology and Behavioral Sciences Collection, Cochrane Central Register of Controlled Trials, and PEDRo. Databases were searched from the first record until July 2021. Randomized controlled trials using exergames as an intervention were included.

RESULTS

The search resulted in 1,048 records. A total of 10 articles published between 2013 and 2020 met inclusion criteria and were reviewed for this study. A positive impact was observed in using exergames to increase shoulders' range of motion, namely, extension, flexion, abduction, internal and external rotation, and functionality postinjury.

CONCLUSIONS

The results of this review provide evidence of the benefits of exergames in shoulder joint rehabilitation. However, more robust clinical trials need to be developed that assess the effectiveness of using exergames as a complement to traditional rehabilitation and assess participants' degree of satisfaction, motivation, and adherence.

Accurate Prediction of Knee Angles during Open-Chain Rehabilitation Exercises Using a Wearable Array of Nanocomposite Stretch Sensors

In this work, a knee sleeve is presented for application in physical therapy applications relating to knee rehabilitation. The device is instrumented with sixteen piezoresistive sensors to measure knee angles during exercise, and can support at-home rehabilitation methods. The development of the device is presented. Testing was performed on eighteen subjects, and knee angles were predicted using a machine learning regressor. Subject-specific and device-specific models are analyzed and presented. Subject-specific models average root mean square errors of 7.6 and 1.8 degrees for flexion/extension and internal/external rotation, respectively. Device-specific models average root mean square errors of 12.6 and 3.5 degrees for flexion/extension and internal/external rotation, respectively. The device presented in this work proved to be a repeatable, reusable, low-cost device that can adequately model the knee's flexion/extension and internal/external rotation angles for rehabilitation purposes.

The Analgesic Effects of Virtual Reality for People with Chronic Pain: A Scoping Review

OBJECTIVE

Although virtual reality is shown to have short-term analgesic effects in acute pain settings, its long-term efficacy in chronic pain conditions has not been established. This scoping review aims to provide a summary of virtual reality approaches explored in chronic primary and secondary pain conditions as defined by the International Association for the Study of Pain.

METHODS

A systematic literature search in Ovid PubMed and Ovid Embase was conducted between January 5 and January 10, 2021, with the use of the Arksey and O'Malley six-step scoping review criteria. Articles were searched via search terms and keywords relating to International Classification of Diseases-defined primary and secondary chronic pain conditions, virtual reality, virtual illusion, distraction, and effects on levels of pain.

RESULTS

Of the 2,118 articles located, 44 were included, which covered a range of primary and secondary chronic pain conditions and used a variety of different computer screen and headset protocols, including gaming, mindfulness, exercise, relaxation, and proprioceptive skills.

CONCLUSIONS

Studies show virtual reality to be an effective analgesic intervention for people with chronic pain. Given user satisfaction, a lack of side effects such as cybersickness, and relief of comorbid symptoms, virtual reality has potential as a worthwhile adjunct to chronic pain management programs, thus enabling patients to take control of their symptoms.

Virtual reality-based rehabilitation in patients following total knee arthroplasty: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Physical therapy is regarded as an essential aspect in achieving optimal outcomes following total knee arthroplasty (TKA). The coronavirus disease 2019 (COVID-19) pandemic has made face-to-face rehabilitation inaccessible. Virtual reality (VR) is increasingly regarded as a potentially effective option for offering health care interventions. This systematic review and meta-analysis investigate VR-based rehabilitation's effectiveness on outcomes following TKA.

METHODS

From inception to May 22, 2021, PubMed/Medline, Embase, Web of Science, the Cochrane Central Register of Controlled Trials, Scopus, PsycINFO, Physiotherapy Evidence Database, China National Knowledge Infrastructure, and Wanfang were comprehensively searched to identify randomized controlled trials (RCTs) evaluating the effect of VR-based rehabilitation on patients following TKA according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and the Cochrane Handbook for Systematic Reviews of Interventions.

RESULTS

Eight studies were included in the systematic review, and seven studies were included in the meta-analysis. VR-based rehabilitation significantly improved visual analog scale (VAS) scores within 1 month (standardized mean difference [SMD]: -0.44; 95% confidence interval [CI]: -0.79 to -0.08, P = 0.02), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) within 1 month (SMD: -0.71; 95% CI: -1.03 to -0.40, P < 0.01), and the Hospital for Special Surgery Knee Score (HSS) within 1 month and between 2 months and 3 months (MD: 7.62; 95% CI: 5.77 to 9.47, P < 0.01; MD: 10.15; 95% CI: 8.03 to 12.27, P < 0.01; respectively) following TKA compared to conventional rehabilitation. No significant difference was found in terms of the Timed Up and Go (TUG) test.

CONCLUSIONS

VR-based rehabilitation improved pain and function but not postural control following TKA compared to conventional rehabilitation. More high-quality RCTs are needed to prove the advantage of VR-based rehabilitation. As the COVID-19 pandemic continues, it is necessary to promote this rehabilitation model.

Exergames to improve Rehabilitation after Anterior Cruciate Ligament Injury: Systematic review and GRADE evidence synthesis

INTRODUCTION

Exergames are a fun, engaging, and interactive form of exercise that has been used in rehabilitation. This systematic review aimed to evaluate the effectiveness of exergames compared to usual rehabilitation after anterior cruciate ligament reconstruction.

METHOD

We performed a Systematic Review and GRADE evidence synthesis. The PRISMA guidelines for systematic reviews were followed. MEDLINE® (Medical Literature Analysis and Retrieval System Online), CINAHL® (Cumulative Index to Nursing and Allied Health Literature), SPORTDiscus, SCOPUS, SciELO (Scientific Electronic Library Online), Cochrane Central Register of Controlled Trials, and PEDro (Physiotherapy Evidence Database) were searched from their first record to May 2021. Randomised controlled trials using exergames as an intervention were included.

RESULTS

Initial literature searches yielded 794 non-duplicated records. After exclusion based on title, abstract, and full text review, five articles were included for analysis. Compared with the control group, the participants in the exergames group showed differences in proprioception and flexion angle difference.

CONCLUSION

Although there is no conclusive evidence that favours exergames over traditional rehabilitation, they did not aggravate the effects of rehabilitation. Nonetheless, exergames can be safe and motivating.

The Use of Gamification in Patients Undergoing Hip Arthroplasty: Scoping Review

Objective: The use of gamification can promote health-related behavior. This article is the first attempt to provide a historical overview of the use of games in patients undergoing hip arthroplasty. Materials and Methods: We conducted a scoping review to map and characterize the games used for the person undergoing hip arthroplasty. To perform this review, the respective descriptors were identified using search syntax appropriate to each of the databases: MEDLINE_ (Medical Literature Analysis and Retrieval System Online), CINAHL_ (Cumulative Index to Nursing and Allied Health Literature), SPORTDiscus, in the Psychology and Behavioral Sciences Collection, SCOPUS, SciELO (Scientific Electronic Library Online), and PEDRo (Physiotherapy Evidence Database). Results: An initial 968 articles were identified, of which 7 articles were included. The domains of the games under analysis essentially focus on aspects of rehabilitation (n = 5), or related (n = 2), and mostly exergames (n = 6). However, the instruments, characteristics, and procedures used to evaluate the games in the included studies have little depth and large variability. Conclusion: Few games exist that support people who have undergone hip arthroplasty. Most of the games under review were exergames to support rehabilitation. Consequently, we recommend developing another type of game with a focus on monitoring, counseling, and/or social support for selfmanagement training in persons undergoing hip arthroplasty.

Virtual Reality Rehabilitation and Exergames—Physical and Psychological Impact on Fall Prevention among the Elderly—A Literature Review

The present review is aimed at the effectiveness of virtual reality (VR) and exergames in the prevention of falls among the elderly. Falls become a significant problem in the aging population and lead to psychological, social, and physical impairment. Prevention of falls is crucial to the well-being of the elderly population and is one of the challenges of contemporary rehabilitation. Recently, in view of the threat of the SARS-CoV-2 pandemic, contactless methods of rehabilitation, including telerehabilitation, appear as valuable rehabilitation tools. This review is based on the PRISMA guidelines and was carried out in five databases: PubMed, Medline, Web of Science, Scopus, and PEDro. Twenty-one randomized controlled trials, focused on the application of VR and exergames in the prevention of falls, were included. This review suggests that VR training in rehabilitation appears to be a promising complement to traditional techniques of physiotherapy to improve specific physical outcomes. VR and exergames could be considered as a complement of standard physiotherapy and its possible continuation at home for elderly. However, further high-quality studies, with carefully designed protocols and proper blinding, are needed.

The effect of virtual reality training on the daily participation of patients: A meta-analysis

BACKGROUND

Virtual reality (VR) training are regarded as promising new tools for rehabilitation, but the effect on patients' daily participation is controversial. This study aimed to evaluate the effect of virtual reality (VR) training on different types of patients' daily participation through a meta-analysis.

METHODS

The PubMed, Cochrane central register of controlled trials, Embase, and web science databases were searched for studies published through September 2020. Thirty-five randomized controlled trials of virtual reality (VR) training compared with conventional treatment, Other electronic rehabilitation systems, usual care for various types of patients were included. All of the studies were available in English. Standardized mean differences (SMD), 95 % confidence intervals (CI), publication bias, and heterogeneity were calculated.

RESULTS

The Virtual reality (VR) training group is better than the control group in daily participation improvement on all types of patients. There was a small, significant effect(p＜0.001; SMD = 0.25[95 %CI,0.14 to 0.36], I² = 0.00 %). Observing only the type of Stroke, the VR training group is still better than the control group in improving patients' daily participation (p＜0.001, SMD = 0.24[95 %CI, 0.11 to 0.37], I2 = 0.00 %). Using the cumulative Meta-analysis method to observe the included literature according to the timeline, Using the cumulative Meta-analysis method to observe the included literature according to the timeline, and it has only achieved positive results since 2015 (Nam-YoNg Lee 2015, p = 0.048, SMD = 0.22[95 %CI,0.00 to 0.44]). The heterogeneity of the studies was not detected, but there is obvious publication bias.

CONCLUSIONS

Because of controversy over obvious publication bias, we need to be cautious about the conclusion that VR is better than the control group in promoting the patient's daily participation.
