Home-based immersive virtual reality physical rehabilitation in paediatric patients for upper limb motor impairment: a feasibility study

TouchMark: Partial Tactile Feedback Design for Upper Limb Rehabilitation in Virtual Reality

The use of Virtual Reality (VR) technology, especially in medical rehabilitation, has expanded to include tactile cues along with visual stimuli. For patients with upper limb hemiplegia, tangible handles with haptic stimuli could improve their ability to perform daily activities. Traditional VR controllers are unsuitable for patient rehabilitation in VR, necessitating the design of specialized tangible handles with integrated tracking devices. Besides, matching tactile stimulation with corresponding virtual visuals could strengthen users' embodiment (i.e., owning and controlling virtual bodies) in VR, which is crucial for patients' training with virtual hands. Haptic stimuli have been shown to amplify the embodiment in VR, whereas the effect of partial tactile stimulation from tangible handles on embodiment remains to be clarified. This research, including three experiments, aims to investigate how partial tactile feedback of tangible handles impacts users' embodiment, and we proposed a design concept called TouchMark for partial tactile stimuli that could help users quickly connect the physical and virtual worlds. To evaluate users' tactile and comfort perceptions when grasping tangible handles in a non-VR setting, various handles with three partial tactile factors were manipulated in Study 1. In Study 2, we explored the effects of partial feedback using three forms of TouchMark on the embodiment of healthy users in VR, with various tangible handles, while Study 3 focused on similar investigations with patients. These handles were utilized to complete virtual food preparation tasks. The tactile and comfort perceptions of tangible handles and users' embodiment were evaluated in this research using questionnaires and interviews. The results indicate that TouchMark with haptic line and ring forms over no stimulation would significantly enhance users' embodiment, especially for patients. The low-cost and innovative TouchMark approach may assist users, particularly those with limited VR experience, in achieving the embodiment and enhancing their virtual interactive experience.

Virtual reality for preoperative patient education: Impact on satisfaction, usability, and burnout from the perspective of new nurses

BACKGROUND

Traditional paper-based preoperative patient education is a struggle for new nurses and requires extensive training. In this situation, virtual reality technology can help the new nurses. Despite its potential benefits, there are studies on patient satisfaction but there is limited information on the usability of virtual reality (VR) technology for new nurses in giving preoperative education to patients.

AIM

To investigate the impact on satisfaction, usability, and burnout of a system using VR technology in preoperative patient education.

METHODS

The study involved 20 nurses from the plastic surgery ward and 80 patients admitted between April and May 2019. Each nurse taught four patients: Two using traditional verbal education and two using virtual reality. The System Usability Scale, After-Scenario Questionnaire, and Maslach Burnout Inventory (MBI) were employed to evaluate the impact of these education methods.

RESULTS

The VR education groups showed a statistically higher satisfaction than the traditional verbal education groups. Among the three subscales of the MBI, emotional exhaustion and personal accomplishment improved statistically significantly. VR was also better in terms of usability.

CONCLUSION

This study suggests VR enhances usability and reduces burnout in nurses, but further research is needed to assess its impact on depersonalization and objective measures like stress and heart rate.

Virtual reality-based therapy after anterior cruciate ligament injury effectively reduces pain and improves knee function, movement patterns, and dynamic balance: A systematic review and meta-analysis

PURPOSE

Virtual reality-based therapy (VRBT) may be an effective physical therapy complement employed in the rehabilitation of patients with anterior cruciate ligament (ACL) injury. This study aims to assess the effectiveness of VRBT in improving pain, knee function, strength, proprioception, flexion range of motion (ROM), and dynamic balance after ACL injury.

METHODS

We conducted this systematic review with meta-analysis following PRISMA criteria. Since inception to June 2024, we searched in PubMed Medline, WOS, SCOPUS, CINAHL and PEDro without publication date and language restrictions. Randomised controlled trials (RCTs), comprising only patients with ACL injury, that assess the effectiveness of VRBT compared to classical interventions on the outcomes of interest were included. PEDro scale was employed to analyze the methodological quality of the RCTs included. Cohen's standardised mean difference (SMD) and its 95% confidence interval (95% CI) was used to calculate the pooled effect in meta-analyses.

RESULTS

Nine RCTs, providing data from 330 participants (26.96 ± 3.11 years, 85% males) were included. The RCTs included showed good methodological quality (PEDro scale = 6.88 points), being, performance and detection biases, the most common biases reported. Meta-analyses showed that VRBT was more effective than classical interventions in reducing pain (SMD = -1.15; 95% CI -1.85 to -0.45; p = 0.001; I2 = 0%), and increasing knee function (SMD = 1.71; 95% CI 0.93 to 2.5; p < 0.001; I2 = 0%), strength (SMD = 0.82; 95% CI 0.4-1.23; p < 0.001; I2 = 0%) and flexion ROM (SMD = 0.7; 95% CI 0.37-1.01; p < 0.001; I2 = 0%). Additionally, VRBT improved postero-medial (SMD = 0.46; 95% CI 0.01-0.9; p = 0.045; I2 = 15.1%) and postero-lateral CoP excursion (SMD = 0.75; 95% CI 0.3-1.21; p = 0.001; I2 = 0%), being effective in improving dynamic balance.

CONCLUSION

VRBT is an effective physical therapy complement to be included in the ACL's rehabilitation programmes due to reduces pain and increases knee function, strength, ROM and dynamic balance after ACL injury.

Feasibility of a home-based home videogaming intervention with a family-centered approach for children with cerebral palsy: a randomized multiple baseline single-case experimental design

BACKGROUND

Worldwide, children with cerebral palsy (CP) living in underserved communities face barriers to accessing motor therapy services. This study assessed the implementation and effectiveness of an 8-week, upper limb (UL) home-based intervention with a movement-tracking videogame (Bootle Blast) in Costa Rican children with CP.

METHODS

Children established a weekly playtime goal and two UL activities of daily living (ADLs) that they would like to improve on. A multiple-baseline, single-case experimental design, was used with the Performance Quality Rating Scale (PQRS) as the repeated measure to track changes in performance of the selected ADLs between the baseline (usual care) and intervention (Bootle Blast) phases. The Canadian Occupational Performance Measure (COPM), the Box and Blocks Test (BBT) and the Children's Hand-Use Experience Questionnaire (CHEQ) were collected before and after the intervention. Technical barriers were documented during weekly video calls with a monitoring therapist. Treatment effect size, slope changes and percentage of non-overlapping data were identified for the PQRS. Descriptive statistics summarized results for the BBT, CHEQ, videogame logs (e.g., playtime) and technical barriers.

RESULTS

Fifteen children participated and 13 completed the intervention. Both participants who dropped out did so after completing baseline assessments, but before experiencing Bootle Blast. Children's mean active playtime (i.e., mini-games targeting the UL) across the 8-weeks was 377 min, while mean total time spent engaging with Bootle Blast (active + passive play time [e.g., time navigating menus, reviewing rewards]) was 728 min. In total, eight technical issues (from five children) were reported, and all but three were resolved within 48 h. Partial effectiveness was associated with the intervention. Specifically, 85% of participants improved on the PQRS and 69% achieved clinically important improvements ≥ 2 points in performance on the COPM. Children improved by 1.8 blocks on average on the BBT, while on the CHEQ, five children had a clinically important increase of 10% of the total number of UL activities performed with both hands.

CONCLUSION

Bootle Blast is a feasible and effective option to facilitate access and engage children with cerebral palsy in UL home rehabilitation. Trial registration Trial registration number: NCT05403567.

Virtual reality current use, facilitators and barriers to implementation in paediatric physiotherapy: cross-sectional online survey of UK paediatric physiotherapists

BACKGROUND

The literature is scarce about virtual reality (VR) use and its integration into clinical practice. Given the growing interest toward using VR in healthcare in the UK, the aims of this survey were to explore its current use by paediatric physiotherapists in clinical practice in the UK, identify the facilitators and barriers to VR implementation in clinical practice and investigate the factors that will enhance intentions to use it in the future.

METHODS

An online survey using Assessing Determinants of Prospective Take-Up of Virtual Reality (ADOPT-VR2) was distributed to UK paediatric physiotherapists through the Association of Paediatric Chartered Physiotherapists. Descriptive statistics and regression analysis were conducted.

RESULTS

Out of 128 responses, 81 UK-based paediatric physiotherapists completed the survey. The therapists worked in the National Health Service, in the private sector and education. Most of the respondents reported not using VR in clinical practice (n = 75; 93%). Only 7% of respondents reported using VR in clinical practice. Attitudes toward VR, compatibility, and the peer influence constructs of ADOPT-VR2 all significantly predicted the behavioural intention to use VR (R2 = 0.612, p = <0.001).

CONCLUSIONS

This study shows that the current use of VR is limited. The findings from this study suggest that multiple factors need to be reconciled to enhance VR implementation. Specifically, therapists need to be provided with time, appropriate training, and financial and technical support. Stakeholders may also need to consider developing practical manuals to ensure therapists are implementing VR consistently and correctly.

Evaluating the impact of virtual reality game training on upper limb motor performance in children and adolescents with developmental coordination disorder: a scoping review using the ICF framework

OBJECTIVE

This scoping review aims to explore published literature testing Virtual Reality (VR) interventions for improving upper limb motor performance in children and adolescents with Developmental Coordination Disorder (DCD). Our primary focus was on the types of VR systems used and the measurement tools employed within the International Classification of Functioning, Disability and Health Children and Youth Version (ICF-CY) domains in these studies.

METHODS

A comprehensive search of six electronic databases up to 11th January 2024 was conducted using predefined terms. Inclusion and exclusion criteria were applied to determine study eligibility, with two authors independently assessing titles, abstracts, and full-text articles.

RESULTS

Out of 788 potential studies, 14 met the eligibility criteria. Studies predominantly utilized non-immersive VR (nVR) systems, for example, commercial platforms such as Nintendo Wii. Most interventions targeted general motor coordination or balance, with only four studies specifically focusing on upper limb motor performance. The Movement Assessment Battery for Children-2 was the predominant assessment tool. However, the use of game scores and trial durations raised concerns about the accuracy of assessments. The majority of studies reported no significant improvement in upper limb motor performance following VR interventions, though some noted improvements in specific tasks or overall outcomes.

CONCLUSION

The findings suggest that, while nVR interventions are being explored for paediatric motor rehabilitation, their impact on enhancing upper limb motor performance in children with DCD is unclear. The variability in intervention designs, outcome measures, and the predominant focus on general motor skills rather than specific upper limb improvements highlight the need for more targeted research in this area.

IMPACT

This review underscores the importance of developing precise and clinically relevant measurement tools in a broader range of VR technologies to optimize the use of VR in therapy for children with DCD. Future research should aim for more rigorous study designs and emerging immersive technologies to maximize therapeutic benefits.

Technological Features of Immersive Virtual Reality Systems for Upper Limb Stroke Rehabilitation: A Systematic Review

Stroke is the second most common cause of death worldwide, and it greatly impacts the quality of life for survivors by causing impairments in their upper limbs. Due to the difficulties in accessing rehabilitation services, immersive virtual reality (IVR) is an interesting approach to improve the availability of rehabilitation services. This systematic review evaluates the technological characteristics of IVR systems used in the rehabilitation of upper limb stroke patients. Twenty-five publications were included. Various technical aspects such as game engines, programming languages, headsets, platforms, game genres, and technical evaluation were extracted from these papers. Unity 3D and C# are the primary tools for creating IVR apps, while the Oculus Quest (Meta Platforms Technologies, Menlo Park, CA, USA) is the most often used headset. The majority of systems are created specifically for rehabilitation purposes rather than being readily available for purchase (i.e., commercial games). The analysis also highlights key areas for future research, such as game assessment, the combination of hardware and software, and the potential integration incorporation of biofeedback sensors. The study highlights the significance of technological progress in improving the effectiveness and user-friendliness of IVR. It calls for additional research to fully exploit IVR's potential in enhancing stroke rehabilitation results.

Effectivity of Virtual Reality to Improve Balance, Motor Function, Activities of Daily Living, and Upper Limb Function in Children with Cerebral Palsy: A Systematic Review and Meta-Analysis

Background

Cerebral palsy (CP) is the most common motor disorder in childhood. CP limits movement, which can interfere with children's daily activities. As a technology that provides intensive mass practice to children, virtual reality (VR) can create an interactive and motivating environment. With the intensity set by the therapist and feedback that can be used to produce individualized therapy, VR has great potential to improve CP patients' quality of life, especially in a safe, enjoyable, and playful environment.

Purpose

This systematic review and meta-analysis sought to determine the effectiveness of VR for children with CP.

Methods

We conducted a comprehensive literature search based on the PRISMA guidelines through PubMed, Scopus, Embase, Wiley, and ProQuest to assess the efficacy of VR in managing children with CP up to 15 September 2022. Risk assessment of bias was performed using Cochrane RoB 2.

Results

Nineteen randomized controlled trials with 467 and 427 patients with CP were included in the intervention and control groups in qualitative and quantitative analyses. Participants consisted of cerebral palsy with hemiplegia (n=7), diplegia (n=2), a combination of both (n=4), and undefined (n=13). From all studies conducted, VR showed significant results where VR could improve balance (MD: 2.71[1.95, 3.48]; p < 0.00001), motor function (MD: 3.73 [1.67, 5.79]; p = 0.0004), and activity daily living (MD: 10.05 [2.89, 17.22]. However, VR showed not effective in improving upper limb function.

Conclusion

With its advantages and excellent effectiveness, VR may improve functional mobility and the quality of life of children with CP.

Pain management in pediatric age. An update

Differently from the adult patients, in paediatric age it is more difficult to assess and treat efficaciously the pain and often this symptom is undertreated or not treated. In children, a selection of appropriate pain assessment tools should consider the age, the cognitive level, the presence of eventual disability, the type of pain and the situation in which it is occurring. Improved understanding of developmental neurobiology and paediatric analgesic drug pharmacokinetics should facilitate a better management of childhood pain. The objective of this update is to discuss the current practice and the recent advances in pediatric pain management.  Using PubMed and the Cochrane Library we conducted an extensive literature analysis on pediatric pain assessment and commonly used analgesic agents in this kind of patients. According to our results, a multimodal analgesic regimen provides a better pain control and a functional outcome in children. Cooperation and communication among the anaesthesiologist, the surgeon and the paediatrician remains essential for successful anaesthesia and pain management in childhood.
