Virtual reality as an adjunctive non-pharmacologic analgesic for acute burn pain during medical procedures

Virtual reality for distraction during painful procedures in pediatric surgery: A randomized clinical trial

PURPOSE

Hospitalization can be stressful and anxiety-inducing for many pediatric surgical patients and their parents. If further procedures or treatments are required, this often leads to additional pain and anxiety and therefore cumulative stress. Very young patients often find themselves for the first time in an uncomfortable environment that they have never experienced before. To counteract their anxiety and pain during painful procedures, a new user-friendly immersive distraction method using a virtual reality (VR) headset was investigated in a clinical study.

METHODS

A total of 34 patients between the ages of 5 and 16 took part in the study and were randomly assigned to the experimental or control group. The children in the experimental group were distracted during treatment by 360° videos on VR glasses while the children in the control group received routine care from the staff. The treatments assessed included the insertion of peripheral intravenous catheters, surgical dressing changes and the insertion and removal of transurethral catheters. Anxiety and pain levels were measured using an FPS-R scale and a FLACC scale.

RESULTS

The results show that, on average, the participants in the intervention group reported less anxiety (regression coefficient RC: -0.86 [-2.68; 0.96], p-value: 0.3429) and pain during procedure (RC: -1.17 [-2.99; 0.65], p-value: 0.1996) and after procedure (RC: -0.54 [-1.71; 0.65], p-value: 0.3616) than in the control group. The duration of procedures has been statistically significant reduced in the intervention group by an average of 5.53 (95 %-confidence interval: [-11.02; -0.04], p-value: 0.0486) minutes. Almost all participants stated that they had found the VR experience good and wanted to use the glasses for a future treatment or intervention.

CONCLUSION

The introduction of VR technology into clinical practice can improve the hospital experience for children and reduce anxiety and pain during painful procedures. VR has been shown to be a useful and effective means of distracting children during painful procedures.

The Effect of Virtual Reality on Chemotherapy-Associated Stress (Cortisol Value), Anxiety, and Pain Symptoms of Mastectomy Patients: A Randomized Controlled Pilot Study

BACKGROUND

Pain, anxiety, and stress are the most common symptoms experienced by patients receiving chemotherapy after breast surgery. Virtual reality (VR) can be used as a method to manage these symptoms.

OBJECTIVE

To determine the effect of VR on chemotherapy-associated stress (salivary cortisol value), anxiety, pain, and vital signs of mastectomy patients.

METHODS

A total of 62 participants were enrolled in this randomized, 2-group design. Participants in the experimental group watched videos with VR glasses during their chemotherapy treatments. Saliva samples were collected from participants in both the control and experimental groups before and immediately after their chemotherapy treatments. The Personal Information Form, state anxiety component of the State-Trait Anxiety Inventory, visual analog scale, and the patients' vital signs were also collected.

RESULTS

The State-Trait Anxiety Inventory state anxiety component and visual analog scale scores and the stress value mean scores differed significantly between the 2 groups at the second data point. There was also a statistically significant decrease in systolic blood pressure and diastolic blood pressure after chemotherapy in the experimental group.

CONCLUSION

The use of VR in women receiving chemotherapy significantly reduced their pain, anxiety, stress and blood pressure from before to immediately following the chemotherapy infusion.

IMPLICATIONS FOR PRACTICE

VR can be an appropriate intervention to reduce pain, anxiety, and stress in patients receiving chemotherapy after mastectomy.

[Impact of HypnoVR© with local anesthesia on pain and anxiety during oocyte pick-up]

OBJECTIVE

Virtual reality with Snow World shows a 45% decrease in painful peaks during the care of burn victims. Hypnosis has anxiolytic effect and modulate the response to pain. HypnoVR© is based on many concepts recognized in medicine accessible without specific training. In our practice, 95% of oocyte pick-up are made with local anesthesia and simple premedication, whereas conscious sedation is recommanded in Europe. HypnoVR© is systematically offered during oocyte pick-up. Our study had to compare the pain felt between the 2 group with or without HypnoVR©, also anxiety, tolerance and satisfaction of patients.

METHOD

It was a prospective comparative, non-randomized, single-center, open-label study. We included all patients who were to benefit from an oocyte pick-up from 18 to 43 years-old. The usual protocol of pick-up was used and it was possible to add HypnoVR©. A questionnaire was distributed to each patient to collect their opinion.

RESULTS

A total of 112 patients were included, 60 without HypnoVR© and 52 with HypnoVR©; 2 were excluded from the main analysis for missing data. There is no statistically significant difference in pain and anxiety between the groups. Patients are satisfied: 90.20% (n=46/52) would like to use it again and 98.04% (n=50/52) would recommend it.

CONCLUSION

Despite the absence of a statistically significant difference, patients are satisfied with HypnoVR© and tolerance is good. It seems interesting to be able to offer it during oocyte pick-up.

Pathophysiology and management of burn injury-induced pain

This review examines the pathophysiology and therapeutic management of burn injury-induced pain (BIP). Burn injury, occurring globally in about 11 million people, often induces the most intense pain, but its management remains suboptimal. The pain often persists even after complete wound healing and hospital discharge causing both long-term disability and neurological dysfunction. The fact that BIP persists well beyond the initial hospitalization is not well recognized and should be underscored as the pain involves even non-burned areas. The pathophysiology of the latter problem is poorly understood and needs further study. Opioids, the mainstay for moderate to severe pain relief after major burn injury, with time, have poor analgesic and serious side effects. Accurate assessment pain of BIP and its biology at different stages of treatment helps to provide effective treatments of the different etiological factors that cause BIP and their sequelae. Based on clinical and pre-clinical studies, we discuss the current knowledge on the underlying cellular and molecular mechanisms in the initiation and persistence of BIP during the acute phase and later phases of injury. Opioid receptor-mediated signaling changes per se and immune microglia responses in concert exaggerate nociceptive behavior. Both burn injury and opioids upregulate spinal NMDA receptor expression and microglia changes, which further exaggerate pain. BIP has inflammatory and neuropathic components. Pharmacological and non-pharmacological approaches currently available for management of BIP is discussed. Areas that need further study include the role of other central and peripheral factors in the exaggeration of pain well beyond wound healing. Novel non-opioid methods to rectify BIP is important to develop in view of the potential for opioid use disorder. The role of microbiome in chronic pain syndromes is an unexplored territory and its relevance to BIP needs further examination. Pruritus or itch, though very common and important in the pharmacotherapy of burns, the discussion of this topic is brief. Extensive review of this topic is beyond the scope of this review in view of the vast body of knowledge and varying and multiple treatment options.

Virtual reality in surgery: minimizing stress and pain in patients undergoing minor-surgical procedures under local anesthesia-results of a feasibility study

BACKGROUND

Virtual reality (VR) technology has gained significant importance in medical practice, particularly as an innovative approach to enhance patient experience and comfort. This prospective feasibility study investigates the impact of using VR headsets on stress and pain reduction during port surgeries under local anesthesia.

METHODS

In this prospective analysis, patients undergoing port implantation at the Klinikum rechts der Isar Technical University Munich were divided into two groups. The intervention group wore VR headsets during the surgical procedure, while the control group did not. Various validated questionnaires were used to measure psychological parameters such as pain perception, stress, calmness, and relaxation. The amount of local anesthesia administered was also documented.

RESULTS

The study results showed that patients in the VR group required significantly less local anesthesia than those in the control group (p = 0.0025). Pain perception in the VR group was significantly lower (p = 0.028). Additionally, self-assessments regarding calmness, relaxation, and satisfaction were significantly improved in the VR group (p < 0.01). A stronger correlation between higher pain catastrophizing scale scores and anesthetic requirements was observed in the VR group, suggesting that VR may offer particular benefits for patients with increased pain sensitivity. Although gender differences were not statistically significant, a trend toward higher anesthetic requirements in male patients was noted. The evaluation of the VR headsets by patients was overwhelmingly positive, indicating high acceptance of the technology.

DISCUSSION

The use of VR headsets during surgical procedures can significantly enhance patient comfort by reducing pain and stress levels. The high patient acceptance and positive evaluations of VR suggest its feasibility for broader clinical application. However, future studies should address potential cognitive biases, compare VR with other distraction methods, and explore its effects on different patient subgroups. Future research should also consider the role of gender-specific factors in the modulation of anesthetic requirements by VR. Additionally, a comprehensive cost-benefit analysis will be crucial for assessing the economic viability of VR technology in healthcare.

CONCLUSION

VR technology represents a promising method to improve patient experience and comfort in surgical settings. The positive outcomes of this study encourage further research to fully capture and validate the potential of VR in medicine, particularly in pain management and stress reduction during various medical procedures.

Current applications and future perspectives of extended reality in radiology

Extended reality (XR) technologies, including virtual reality (VR), augmented reality (AR), and mixed reality (MR), hold transformative potential for radiology. This review examines the current applications, benefits, limitations, and future prospects of XR in radiology, with a focus on education, diagnostics, interventional procedures, and patient interaction. A comprehensive literature search of PubMed, Scopus, and Web of Science databases identified relevant publications from 1992 to 2024. Key studies were selected for detailed discussion. XR technologies enhance radiology education by offering immersive learning experiences that improve the proficiency and confidence of professionals. In diagnostics, XR improves the accuracy and efficiency of ultrasound and CT imaging and aids in precise patient positioning. For interventional radiology, XR provides valuable tools for training and real-time procedural planning, leading to better patient outcomes. Additionally, XR improves patient-doctor interactions, reducing anxiety and enhancing the consent process. Despite challenges such as high costs, technical limitations, and the need for extensive clinical validation, the potential benefits of XR underscore its value as a significant tool in radiology. Addressing these challenges will be essential for the widespread adoption and integration of XR in radiology, ensuring its potential benefits are fully realized. This review highlights the transformative impact of XR technologies on radiology, emphasizing the need for further research and development to harness their full capabilities and improve patient care.

Neurobiological Mechanisms of Enhanced Pain-Relieving Transcutaneous Electrical Nerve Stimulation via Visuo-Tactile Stimulation in Immersive Virtual Reality: Randomized Controlled Trial

BACKGROUND

Enhancing the effectiveness of current pain relief strategies is a persistent clinical challenge. Although transcutaneous electrical nerve stimulation (TENS) is used in various painful conditions, its effectiveness may decline over time, requiring additional pain management strategies. Immersive virtual reality (VR) with personalized visuo-tactile stimulation has demonstrated analgesic properties. Nevertheless, whether visuo-tactile stimulation can enhance the pain-relieving outcomes of TENS and its underlying neurophysiological mechanisms remains largely unknown.

OBJECTIVE

The study aims to investigate whether the integration of visuo-tactile stimulation with TENS can enhance the pain-relieving outcomes of TENS alone, and we also aim to explore the brain mechanisms underlying the analgesic effect of this integrated intervention.

METHODS

In this study, 75 healthy participants were enrolled and randomly assigned to 1 of 3 groups: congruent TENS-VR (TENS-ConVR) and 2 control groups (incongruent TENS-VR [TENS-InVR] and TENS alone). In the context of TENS-ConVR, we combined TENS and VR by connecting TENS-induced paresthesia with personalized visual bodily feedback. The visual feedback was designed to align with the spatiotemporal patterns of the paresthesia induced by TENS. A pain rating task and a 32-channel electroencephalography were applied.

RESULTS

Two-way ANOVAs showed that TENS-ConVR exhibited a statistically greater reduction in pain rating (F1,48=6.84; P=.01) and N2 amplitude (F1,48=5.69; P=.02) to high-intensity pain stimuli before and after stimulation than TENS alone. The reduction of brain activity was stronger in participants who reported stronger pain-relieving outcomes. TENS-ConVR reduced the brain oscillation in the gamma band, whereas this result was not found in TENS alone.

CONCLUSIONS

This study observed that combining TENS and visual stimulation in a single solution could enhance the pain-relieving effect of TENS, which has the potential to improve the effectiveness of current pain management treatments.

The impact of a virtual wound on pain sensitivity: insights into the affective dimension of pain

Background

The perception of pain is difficult to assess due to the complex combination of various components related to nociception, experience, and cognition. There are currently no biomarkers to assess the affective component of pain in healthy volunteers. Using Virtual Reality (VR), it may be possible to assess changes in pain perception when adding an affective component to painful stimulation.

Methods

In this two-visit feasibility study, we assess the effect of a simulated wound in VR on the electrical pain detection (PDT) and tolerance (PTT) threshold in 24 healthy male study participants. The VR simulation presented a copy of the research room from first person view. Prior to each VR assessment, study participants were primed by interacting with the VR environment. Two conditions were assessed: (1) VR-Wound: a burn-wound, smoke, and electrical sparks become visible and audible with increasing stimulus intensity, and (2) VR-neutral: no additional aspects. The PDT and PTT to electrical stimuli were recorded during both VR conditions and outside of VR. VAS-Questionnaires were used to assess unpleasantness and fear.

Results

The PDT decreased when a virtual wound is presented compared to a neutral condition. Study participants experienced the electrical stimulation as more painful and more intense during the wound simulation than during the neutral condition. The effect was more pronounced during the second visit.

Conclusion

VR enhanced the perception of pain, thereby providing new insights into the affective component of pain. Further testing of this methodology is warranted by performing a clinical study that evaluates drug effects on the affective component of pain.

The influence of time and visualization on neurofeedback-guided parietal alpha downregulation and sense of presence in virtual reality

In an EEG-based near real-time neurofeedback (NF) study in two parts using high immersive virtual reality (VR) we successfully trained healthy participants to downregulate their parietal alpha power, a neurophysiological correlate previously associated with enhanced sense of presence. The first part included n = 10 participants equipped with 128 and 64 channels gel-based active EEG electrodes in 10 sessions using standard bar feedback presented on a computer monitor. Nine participants were better than random at the 10th session and four improved over time. For the second part we reduced the electrode subset to 9 sponge-based active channels (2 frontal, 7 parietal around Pz) and a portable amplifier. Participants (n = 10) were trained each session within VR using bar feedback projected on a wall in the first 5 sessions and then controlling the flow of a water fountain. Participants were able to significantly downregulate their parietal alpha power after 5 sessions and learning occurred at the group level, with 7 participants showing both improvement over time and ability to modulate. However, these results were only shown during the fountain feedback and both ability and learning were non-significant in the VR projector condition. Based on self-reports, after excluding participants performing movements and closing their eyes, no particular mental strategy, such as relaxation, breathing or mental calculus was identified to help with alpha modulation. The hypothesized behavioral effect on sense of presence was not found nor any neurophysiological changes in fronto-parietal connectivity. While NF did not improve the sense of presence, we succeeded in adapting real-time NF training for high immersive VR technology via seamlessly embedded feedback in the form of a water fountain. The study showcases that NF is possible with sponge electrodes and portable EEG that would prove convenient in end-user (at home) or clinical setup. The dataset is publicly available on Openneuro.org.

Investigation into nurses' emotion regulation while causing pain to adult patients during burns dressing changes: a qualitative study

BACKGROUND

Burns can cause patients significant pain at the time of injury and during subsequent treatment. Other people's pain often elicits empathic responses in observers. However, effective emotion regulation strategies are needed to manage personal distress, which may otherwise inhibit helping behaviour.

METHODS

This study used an interpretative qualitative approach to conduct semi-structured interviews with burns nurses. Interviews explored emotion regulation strategies used by nurses whilst causing pain to adult patients during burns dressing changes. Transcripts were analysed using Braun and Clarke's six stages of thematic analysis.

RESULTS

Eight burns nurses participated in the interviews. Thematic analysis developed five themes: Emotions get in the way of being a good nurse; Pain's an inevitable and justifiable part of treatment and healing; If I'm not made aware of the pain, maybe there is no pain; The pain's due to other factors, not my actions; and Sometimes it's too much.

CONCLUSION

Burns nurses' attempts at regulating their emotions were influenced by their beliefs about what makes a 'good' nurse. Gross's model of emotion regulation provides a useful framework for understanding these strategies, but further research is needed into the helpfulness thereof for nurses and patients.

A randomized controlled trial comparing immersive virtual reality games versus nitrous oxide for pain reduction in common outpatient procedures in pediatric surgery

BACKGROUND

Children often experience anxiety and pain during minor surgical procedures, prompting the search for effective pain management strategies beyond traditional pharmaceutical approaches. This study aims to evaluate the efficacy of virtual reality (VR) as a pain reduction method in pediatric outpatient surgical interventions compared to the standard use of nitrous oxide. The research questions explore pain reduction levels, patient preferences, enjoyment during VR use, and the time limit of the VR application.

METHODS

The study employs a randomized controlled trial design, utilizing VR technology and nitrous oxide in separate groups in 100 children at the age from 6 to 15 undergoing minor surgical procedures. Outcomes are monitored directly after the intervention and two weeks following the procedure. The primary outcome measure is the pain level, assessed using visual face and visual analog scales. Secondary outcomes are the fun and/or fear experienced during the intervention, the willingness to undergo the same procedure again (if necessary), and whether there is a time limit with the VR application compared to nitrous oxide. The study also considers adverse events and safety measures.

DISCUSSION

The study aims to address a significant research gap in pediatric pain management strategies, as it is the first randomized controlled trial designed to compare pain levels using VR versus a control group with nitrous oxide analgosedation in children undergoing minor surgical procedures. Preliminary evidence suggests VR may offer a viable alternative to traditional pain management methods, as VR technology could be an effective distraction and pain management tool for pediatric patients undergoing outpatient surgical procedures.

Effect of Virtual Reality on Pain, Anxiety, and Vital Signs in Endoscopy

AIM

This study was conducted to evaluate the effect of relaxation exercise with VR (Virtual Reality) glasses on pain severity, anxiety level, and vital signs in patients undergoing endoscopy.

METHODS

This is a quasi-experimental study including a control group with a pretest/post-test applied. This study was conducted with a total of 100 patients, including 50 patients in the intervention and 50 patients in the control group. The data were collected by using Personal Information Form, Visual Analogue Scale (VAS), Visual Anxiety Scale, Vital Signs Form and Virtual Reality Glass Application Satisfaction Form.

RESULTS

In the inter group evaluation, the mean systolic and diastolic blood pressure, heart rate and respiratory rate of the patients in the experimental group after endoscopy were found to be lower than the control group (p < .05). When the effect size value (Cohen d) of this finding was examined, it was found that the application of virtual reality glasses had a large effect on systolic and diastolic blood pressure and a moderate effect on respiration and heart rate. It was found that the mean VAS score of the patients in the control group after the endoscopy procedure was significantly higher than their mean values before the procedure (p = .001). There was no statistically significant difference in the mean VAS scores, anxiety scores and O2 saturation values of the patients in the experimental and control groups after the endoscopy. The mean virtual reality glasses satisfaction value of the patients was found to be 6.98.

CONCLUSION

Relaxation exercise performed with virtual reality glasses has positive effects on mean systolic and diastolic blood pressure values, heart rate and respiratory rate in patients undergoing endoscopy. In line with these results, it is recommended that the use of virtual reality glasses during endoscopy should be widespread by nurses.

The benefits and safety of a virtual reality intervention in patients suffering from acute and chronic pain: A pilot study

Background

To overcome the challenge of psychotherapist scarcity in applying pain psychotherapy in clinical practice, we developed a virtual reality (VR) program delivering weeks of pain psychotherapy without psychotherapists, with a focus on minimizing the risk of motion sickness.

Objectives

We conducted a single-arm pilot study to assess the efficacy and motion sickness associated with a VR session delivering guided imagery and breathing techniques selected from the initial course of our VR program, involving patients suffering from various acute and chronic pain.

Methods

Patients underwent a 15-min VR session. Pain-related and anxiety ratings using a 0-10 numerical rating scale were collected pre-, during-, post-VR and in 6-h follow-up. Motion sickness symptoms were assessed using Simulator Sickness Questionnaire pre- and post-VR.

Results

Patients (n = 73) reported their perceived pain intensity and anxiety reduced significantly from pre- to post-VR by 22.9% and 45.0% (all p < 0.0001), respectively. Such modulatory effects of VR in pain perception and anxiety persisted at 30 min, 1 h, 2 h, and 6 h post-VR (all p < 0.0001). The pre-post beneficial effects of VR were independent from patients' demographic characteristics and their pain duration. Importantly, only six patients (8.2%) had post-VR motion sickness symptoms, and only one patient reported moderate level of severity.

Conclusion

These findings suggest the selected VR session delivering pain psychotherapeutic techniques may be effective and tolerable for patients with varying pain conditions, which provides initial evidence for the development of future randomized controlled trials of the complete VR program.

On-Table Virtual Reality to Reduce Anxiety/Distress during Radiation Treatments: A Pilot Randomized Trial

We report the first randomized trial of a virtual reality (VR) headset used on-table during external beam radiation therapy (RT) treatments to reduce anxiety/distress during receipt of RT. A small pilot study was conducted among 10 patients, with VR randomized to start in the first week ("immediate VR") versus the second week ("delayed VR") of treatment. All patients (100%) in the immediate VR group had declines in measured distress scores after their first radiation treatment, compared to only 1 patient (16.7%) in the delayed VR group (P = .048), yet score declines generally did not meet the minimal clinically important difference threshold in the context of overall low distress scores at baseline. By day 5 of treatment, distress score changes were similar between immediate and delayed VR groups. Overall, 80% of patients in the study, including all patients with moderate or high levels of baseline anxiety/distress, reported that on-table VR improved their RT experience and/or they would recommend VR to others. We propose that on-table VR is a readily available, nonpharmacologic intervention that can be used to help reduce anxiety/distress associated with RT and may be particularly helpful at the start of treatment among those with moderate/high baseline levels of anxiety/distress.

Factors Impacting the Adoption and Potential Reimbursement of a Virtual Reality Tool for Pain Management in Switzerland: Qualitative Case Study

Background

Pain and its adequate treatment are an issue in hospitals and emergency departments (EDs). A virtual reality (VR) tool to manage pain could act as a valuable complement to common pharmaceutical analgesics. While efficacy could be shown in previous studies, this does not assure clinical adoption in EDs.

Objective

The main aim of this study was to investigate which factors affect the adoption and potential reimbursement of a VR tool for pain management in the ED of a Swiss university hospital.

Methods

Key informant interviews were conducted using in-depth semistructured interviews with 11 participants reflecting the perspectives of all the relevant stakeholder groups, including physicians, nurses, patients, health technology providers, and health insurance and reimbursement experts. The interviews were recorded and transcribed, and the extracted data were systematically analyzed using a thematic analysis and narrative synthesis of emergent themes. A consolidated framework for eHealth adoption was used to enable a systematic investigation of the topic and help determine which adoption factors are considered as facilitators or barriers or as not particularly relevant for the tool subject of this study.

Results

According to the participants, the three key facilitators are (1) organizational environment; (2) tension for change, ease of use, and demonstrability; and (3) employee engagement. Further, the three key barriers to adoption are (1) workload, (2) changes in clinical workflow and habit, and (3) reimbursement.

Conclusions

This study concludes that the adoption of a VR tool for pain management in the ED of the hospital subject of this study, although benefiting from a high tension for change in pain and workload management, is highly dependent on the respective organizational environment, engagement of the clinical staff, and reimbursement considerations. While tailored incentive structures and ambassador roles could benefit initial adoption, a change in the reimbursement landscape and further investigation of the positive effects on workflow effectiveness are required to drive long-term adoption.

The effect of virtual reality-based interventions on pain in burn wound care in burn patients: A systematic review and meta-analysis

OBJECTIVE

The aim of this systematic review and meta-analysis was to evaluate the effect of virtual reality on pain in adult burn patients.

METHOD

A comprehensive systematic search was conducted on international electronic databases such as PUBMED, Web of Science, Science Direct, CINAHL, Scopus, TÜBİTAK-ULAKBİM, Dergipark and TR Dizin with keywords. This systematic review and meta-anaysis was developed using the PRISMA checklist. The risk of bias was assessed independently for each included study by using the Cochrane risk of bias tools.

RESULTS

Based on the results of systematic review it was decided to include 15 studies in meta analyses. Based on fifteen pooled studies, the estimated SMD was minus 0.62 with a 95 % CI of minus1.15 and minus 0.09 according to the results of the random effects model as recommended by heterogeneity tests. Of pooled 15 studies, 11 studies found less pain score among VR patients, while the remaining four reported higher pain score among VR patients.

CONCLUSIONS

The results show that virtual reality can be used effectively in pain management during burn care in adult patients. Since the number of studies in adult burn patients is very limited, it is recommended to conduct large-sample studies with high level of evidence including nursing interventions on this issue.

The Role of Virtual Reality in the Management of Irritable Bowel Syndrome

PURPOSE OF REVIEW

Irritable bowel syndrome (IBS) is a disorder of gut-brain interaction that significantly impacts health-related quality of life (HRQOL). This article explores the potential role of virtual reality (VR)-based cognitive behavioral therapy (CBT) in treating patients with IBS.

RECENT FINDINGS

While CBT is a proven, skills-based therapy approach that modifies behaviors and alters dysfunctional thinking patterns to influence the gut-brain axis and improve IBS symptoms, it is rarely prescribed given a paucity of CBT-trained clinicians. We developed a novel VR program that delivers a standardized CBT program over an 8-week period to help patients manage their symptoms. In initial qualitative validation testing, patients expressed positive perceptions about using VR CBT for IBS. Home-based, standardized VR CBT has the potential to be an effective and scalable treatment option for patients with IBS. While initial studies have shown proof-of-concept definitive randomized controlled trials are needed to demonstrate the efficacy of self-administered VR CBT in IBS.

Effects of Immersive Virtual Therapy as a Method Supporting the Psychological and Physical Well-Being of Women with a Breast Cancer Diagnosis: A Randomized Controlled Trial

This study aimed to evaluate the effectiveness of virtual reality (VR) in the mental state and quality of sleep improvement and physical activity (PA) increase of patients diagnosed with breast cancer (BC). A total of 33 subjects divided into experimental (EG, n = 17) and control (CG, n = 16) groups were assessed with the Mental Adjustment to Cancer Scale (Mini-MAC), International Physical Activity Questionnaire (IPAQ), Pittsburgh Sleep Quality Index (PSQI), and the Modified Hospital Anxiety and Depression Scale (HADS-M) at four time points. The experimental intervention consisted of eight VR TierOne sessions. Significant differences favoring the EG were identified in the group x time interactions for the main outcomes: destructive style of coping with the disease (p < 0.001), walking (p = 0.04), moderate (p < 0.001) and overall activity (p = 0.004), quality of sleep (p < 0.001), depressive symptoms (p < 0.001), anxiety levels (p < 0.001), aggression levels (p = 0.002), and overall HADS (p < 0.001). Trends, favoring the EG, in the constructive style of coping, sedentary behavior and intensive PA, and sleep efficiency and sleeping time were also found. A VR intervention improves general well-being in terms of the measured parameters.

Effects of Virtual Reality Therapy for Patients With Breast Cancer During Chemotherapy: Randomized Controlled Trial

Background

Patients with breast cancer endure high levels of psychological and physical pain. Virtual reality (VR) may be an acceptable, safe intervention to alleviate the negative emotions and pain of patients with cancer.

Objective

We aimed to test the long-term effects of VR on psychological distress and quality of life (QOL) with traditional care in Chinese patients with breast cancer. We also explored the intervention mechanism and the acceptability of VR.

Methods

A total of 327 eligible participants were randomly assigned to a VR intervention group or a control group. The Distress Thermometer, QLQ-C30 (Quality of Life Questionnaire version 3.0), and Virtual Reality Symptom Questionnaire were assessed at baseline, postintervention (3 mo), and follow-up (6 mo). Analysis followed the intention-to-treat (ITT) principle. The generalized estimating equations model was used to analyze the longitudinal data, and the PROCESS macro was used to analyze the mediating effect.

Results

Compared with the control group, patients with breast cancer in the VR group had lower distress scores (P=.007), and higher health-related QOL scores (physical, role, emotional, cognitive, and social functioning) after 6 months (P<.05). Psychological distress had mediating effects on the longitudinal association between VR and the health-related QOL (indirect effect=4.572-6.672, all P<.05).

Conclusions

VR intervention technology may help reduce distress and improve QOL for patients with breast cancer over time. By incorporating a mediating analysis, we showed that the QOL benefits of VR intervention was manifested through positive effects on psychological distress risk factors.

Enhancing Pediatric Dental Care: The Influence of Virtual Reality

OBJECTIVE

 The purpose of this study was to assess the effects of virtual reality (VR) in reducing pain and anxiety levels in children. The study also compared active and passive distraction methods using VR during the delivery of inferior alveolar nerve blocks (IANBs) in dental procedures in children.

MATERIAL AND METHODS

 The study comprised 45 preschool patients, aged between 4 and 6 years, with no prior dental anesthetic experience. The participants were randomly assigned to three groups based on the sort of management style: Group A used the tell-show-do technique, Group B engaged in passive distraction by watching cartoons using a VR headset, and Group C participated in active distraction by playing games using a controller with the VR headset. Pain and anxiety were evaluated using physiological measurements, namely by analyzing the variations in blood pressure, heart rate, and oxygen saturation before and after the administration of IANB. Psychological assessments were conducted using the Wong-Baker faces scale, Modified Dental Anxiety scale questionnaires, and Revised Face, Legs, Activity, Cry and Consolability scale after administering IANB.

RESULTS

 The physiological outcomes revealed no statistically significant differences in blood pressure and oxygen saturation. However, there was a statistically significant increase in the heart rate in group A compared with groups B and C. In terms of psychological measurements, groups B and C exhibited a significant improvement in pain experience and a decrease in anxiety.

CONCLUSION

 This study concluded that VR reduced pain and anxiety levels in its passive and active forms.

Effects of motor imagery using virtual reality on pain sensitivity and affect in healthy individuals: a prospective randomized crossover study

OBJECTIVE

Exercise induces a hypoalgesic response and improves affect. However, some individuals are unable to exercise for various reasons. Motor imagery, involving kinesthetic and visual imagery without physical movement, activates brain regions associated with these benefits and could be an alternative for those unable to exercise. Virtual reality also enhances motor imagery performance because of its illusion and embodiment. Therefore, we examined the effects of motor imagery combined with virtual reality on pain sensitivity and affect in healthy individuals.

DESIGN

Randomized crossover study.

SETTING

Laboratory.

SUBJECTS

Thirty-six participants (women: 18) were included.

METHODS

Each participant completed three 10-min experimental sessions, comprising actual exercise, motor imagery only, and motor imagery combined with virtual reality. Hypoalgesic responses and affective improvement were assessed using the pressure-pain threshold and the Positive and Negative Affect Schedule, respectively.

RESULTS

All interventions significantly increased the pressure-pain threshold at the thigh (P < .001). Motor imagery combined with virtual reality increased the pressure-pain threshold more than motor imagery alone, but the threshold was similar to that of actual exercise (both P ≥ .05). All interventions significantly decreased the negative affect of the Positive and Negative Affect Schedule (all P < .05).

CONCLUSIONS

Motor imagery combined with virtual reality exerted hypoalgesic and affective-improvement effects similar to those of actual exercise.

CLINICAL TRIALS REGISTRATION

Synchronization of a Virtual Reality Scenario to Uterine Contractions for Labor Pain Management: Development Study and Randomized Controlled Trial

Background: Labor is described as one of the most painful events women can experience through their lives, and labor pain shows unique features and rhythmic fluctuations. Purpose: The present study aims to evaluate virtual reality (VR) analgesic interventions for active labor with biofeedback-based VR technologies synchronized to uterine activity. Materials and Methods: We developed a VR system modeled on uterine contractions by connecting it to cardiotocographic equipment. We conducted a randomized controlled trial on a sample of 74 cases and 80 controls during active labor. Results: Results of the study showed a significant reduction of pain scores compared with both preintervention scores and to control group scores; a significant reduction of anxiety levels both compared with preintervention assessment and to control group and significant reduction in fear of labor experience compared with controls. Conclusion: VR may be considered as an effective nonpharmacological analgesic technique for the treatment of pain and anxiety and fear of childbirth experience during labor. The developed system could improve personalization of care, modulating the multisensory stimulation tailored to labor progression. Further studies are needed to compare the synchronized VR system to uterine activity and unsynchronized VR interventions.

Use of Biofeedback-Based Virtual Reality in Pediatric Perioperative and Postoperative Settings: Observational Study

BACKGROUND

Biofeedback-based virtual reality (VR-BF) is a novel, nonpharmacologic method for teaching patients how to control their breathing, which in turn increases heart rate variability (HRV) and may reduce pain. Unlike traditional forms of biofeedback, VR-BF is delivered through a gamified virtual reality environment, increasing the accessibility of biofeedback. This is the first study to systematically integrate VR-BF use in the pediatric perioperative setting, with the ultimate goal of evaluating the efficacy of VR-BF to reduce pain, anxiety, and opioid consumption once feasibility and acceptability have been established.

OBJECTIVES

The primary objective was to develop a clinical trial protocol for VR-BF use in the pediatric perioperative setting, including preoperative education and training, and postoperative application of VR-BF in children undergoing surgery. A secondary objective was to evaluate the patient and parent experience with VR-BF.

METHODS

A total of 23 patients (12-18 years of age) scheduled for surgery at Nationwide Children's Hospital were recruited using purposive sampling. Following training, participants independently completed a daily, 10-minute VR-BF session for 7 days before surgery and during their inpatient stay. Participants could use VR-BF up to 2 weeks after hospital discharge. Patient- and session-level data of VR-BF usage and achievement of target HRV parameters were measured to identify the optimal frequency and duration of sessions before and after surgery for this population. Standardized questionnaires and semistructured interviews were conducted to obtain qualitative information about patients' experiences with VR-BF.

RESULTS

Patient-level data indicated that the highest odds of achieving 1 session under target HRV parameters was after 4 sessions (odds ratio [OR] 5.1 for 4 vs 3 sessions, 95% CI 1.3-20.6; OR 16.6 for 3 vs 2 sessions, 95% CI 1.2-217.0). Session-level data showed that a session duration of 9 to 10 minutes provided the greatest odds of achieving 1 session under target HRV parameters (OR 1.3 for 9 vs 8 min, 95% CI 1.1-1.7; OR 1.4 for 8 vs 7 min, 95% CI 1.1-1.8; OR 1 for 10 vs 9 min, 95% CI 0.9-1.2). Qualitative data revealed patient satisfaction with the VR-BF technology, particularly in managing perioperative stress (17/20, 85%). Few patients reported VR-BF as beneficial for pain (8/20, 40%).

CONCLUSIONS

Children and adolescents undergoing surgery successfully learned behavioral strategies with VR-BF with 10-minute sessions once daily for 5 days. To integrate VR-BF as a therapeutic intervention in a subsequent clinical trial, patients will be instructed to complete three 10-minute sessions a day for 7 days after surgery.

No pain relief by virtual reality during hysterosalpingography (HSG): results from a randomized controlled trial

STUDY QUESTION

Is virtual reality (VR) an effective non-pharmacological tool to reduce procedural pain during hysterosalpingography (HSG)?

SUMMARY ANSWER

An HSG with VR does not reduce procedural pain scores compared to an HSG without VR.

WHAT IS KNOWN ALREADY

An HSG is often experienced as painful and uncomfortable. VR has been proven successful to reduce acute procedural pain during a variety of medical procedures and interventions.

STUDY DESIGN, SIZE, DURATION

We performed a two-centre open-label randomized controlled trial between January 2021 and October 2022.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Women scheduled for HSG as part of their infertility work-up were screened for participation. After informed consent, women were randomized between HSG with or without VR. Due to the nature of the intervention, the study was not blinded. VR was administered by a head-mounted device displaying nature movies and/or relaxation exercises. The primary endpoint was procedural pain measured using VAS (scale 0.0-10.0 cm). Procedural pain was divided into overall pain score and peak pain score during the procedure. It was measured immediately after HSG. Secondary endpoints included patient satisfaction, VR preferences, and adverse effects of VR.

MAIN RESULTS AND THE ROLE OF CHANCE

We included a total of 134 women, 69 to the intervention group (HSG with VR) and 65 to the control group (HSG without VR). The mean VAS for peak pain was 6.80 cm (SD 2.25) in the intervention group versus 6.60 cm (SD 2.40) in the control group (mean difference 0.28 (95% CI -0.57, 1.12), P = 0.52). The mean VAS for overall pain was 5.00 cm (SD 2.10) in the intervention group versus 4.90 cm (SD 2.13) in the control group (mean difference 0.06 (95% CI -0.71, 0.84), P = 0.88). The expectation that VR would be a good distraction from pain during HSG was correlated with both overall and peak pain scores. When correcting for this expectation, we found that women in the intervention group reported significantly higher scores, both in peak (adjusted MD 0.58 (95% CI -0.81, 1.97), P = 0.021) and overall (adjusted MD 0.43 (95% CI -0.84, 1.71), P = 0.013) pain, compared to the control group. There were no differences in the prevalence of symptoms that were considered as adverse effects of VR.

LIMITATIONS, REASONS FOR CAUTION

The study was not blinded. Reasons for declining participation in the study were anxiety or wanting full control during HSG, which might have created selection bias. The distraction score possibly indicates that the level of VR immersiveness was not optimal due to the lack of sound and/or the type of VR applications. Future studies should investigate whether more immersive or interactive VR applications could decrease procedural pain scores during HSG.

WIDER IMPLICATIONS OF THE FINDINGS

Since VR does not reduce procedural pain, this additional tool should not be used during HSG.

The effect of virtual reality glasses on dental anxiety during scaling and root planing in patients with periodontitis: A randomized controlled clinical trial

OBJECTIVES

This study aimed to evaluate the effect of virtual reality distraction (VRD) on dental anxiety during scaling and root planing (SRP) in periodontitis patients.

MATERIALS AND METHODS

This randomized controlled split-mouth study included 60 patients who scored 9 or above on the dental anxiety scale (DAS) and required SRP in at least two quadrants with at least five teeth and two sites with a probing depth of ≥4 mm. Randomly chosen quadrants were treated using virtual reality glasses, and other quadrants were treated without glasses at the same visit. During VRD, a video of nature scenes was projected onto the screen in front of the patient's eyes. DAS and a visual analogue scale about patient feelings were applied at the end of the procedure.

RESULTS

With VRD, the scale value of pain and discomfort level (VASP) was significantly reduced (p = 0.01, d = 0.57). Starting treatment without glasses significantly decreased VASP in both control and test sides (p = 0.00, d = 0.85; p = 0.00, d = 0.80, respectively) and increased the sensation of immersion and realism (p = 0.03, d = 0.45; p = 0.02, d = 0.46, respectively). Intraoperative and postoperative DAS values were significantly lower in patients who started treatment without VRD (p = 0.04, d = 0.34; p = 0.02, d = 0.44, respectively). Of the patients, 63.3% preferred VRD in the subsequent treatment. While patient preference did not correlate with sex, it correlated with age (r = -0.48, p = 0.01).

CONCLUSIONS

The VRD and initiating SRP procedure with VRD affected the pain and discomfort level in anxious periodontitis patients. In addition, the anxiety level was also affected by starting the procedure with glasses.

Pediatric Burns: From Acute Care Through Reconstruction in 2024

Children are disproportionately affected by burn injuries. Differences between adult and pediatric burns range from epidemiologic characteristics to pathophysiological considerations, which vary between different age subgroups. All these factors must be considered in each phase of burn care. This article reviews the most important aspects of the management of a pediatric burned patient starting from the acute through reconstructive phases.

Virtual reality for interventional radiology patients: a preliminary study

PURPOSE

The aim of this prospective study was to evaluate the tolerance and feasibility of using virtual reality headsets with patients during interventional radiology procedures.

MATERIAL AND METHOD

In this single-center prospective study, the use of a virtual reality headset in addition to the usual analgesic and anxiolytic treatment was proposed to all patients presenting in the interventional radiology department from December 2020 to June 2022. Exclusion criteria were as follows: (1) patients with whom it was not possible to communicate (2) epileptic patients, (3) non-verbal patients, and (4) pregnant women. The main objective was to evaluate the safety of the procedure by screening complications during and after the procedure. The second objective was to evaluate feasibility, as defined by the number of patients using the helmet until the end of the procedure. Effectiveness (patient's self-evaluation of pain and anxiety), comfort, satisfaction, emotions felt, sense of security, and feeling of immersion were also evaluated. Caregivers completed a feedback questionnaire.

RESULTS

Virtual reality headsets were offered to 100 patients, 9 of whom declined. Procedures were achieved in 93.5% of cases: 6/91 patients removed the headset before the end of the procedure. There were minor adverse events in 2/85 (2.3%) procedures (discomfort and nausea) and no major adverse events. 93.9% of patients found an overall benefit, and 90.2% would recommend virtual reality to another patient. 94.4% of caregivers were satisfied with the virtual reality equipment. The mean pain level was 2.5 ± 2.7 before the procedure, 3.3 ± 2.5 during the procedure, and 1.6 ± 2.7 after the procedure. Mean anxiety scores were 4.6 ± 2.9 before the procedure, 3.1 ± 2.7 during the procedure, and 1.1 ± 1.9 after the procedure.

CONCLUSION

The use of virtual reality technology as a complement to traditional therapy for procedures under local anesthesia is feasible and safe in interventional radiology and can be beneficial for pain and anxiety management.

Effects of Virtual Reality on Pain, Anxiety, Patient Satisfaction in Coronary Angiography: A Randomized Trial

BACKGROUND

Since patients are conscious during the coronary angiography procedure, they may experience pain and anxiety regarding possible complications and an uncertain outcome.

AIM

This study was conducted to determine the effects of virtual reality application on pain severity, anxiety level, and patient satisfaction in patients who undergo coronary angiography.

METHOD

This randomized controlled study was conducted with a total of 70 patients, including 35 patients in the intervention and 35 patients in the control group. Apart from their routine treatment, virtual reality glasses application was used in the intervention group patients during the procedure. The patients in the control group were given only routine treatment. Data were collected by using "Descriptive Information Form", "Visual Analogue Scale (VAS)", Anxiety Assessment Scale (AAS), "Physiological Symptoms of Anxiety Follow-up Form", and "Virtual Reality Glass Application Satisfaction Form".

RESULTS

Mean post-intervention scores of VAS, AAS, heart rate, diastolic and systolic blood pressure, respiratory rate of the intervention group decreased significantly compared with the control group, while O2 saturation value was found to increase significantly.

CONCLUSIONS

In this study, it was found that virtual reality application was effective in reducing pain and anxiety, increasing patient satisfaction, and normative regulation of vital signs in patients who undergo coronary angiography.

A Preparatory Virtual Reality Experience Reduces Anxiety before Surgery in Gynecologic Oncology Patients: A Randomized Controlled Trial

Perioperative anxiety is common among patients undergoing surgery, potentially leading to negative outcomes. Immersive virtual reality (VR) has shown promise in reducing anxiety in various clinical settings. This study aimed to evaluate the effectiveness of VR in reducing perioperative anxiety in patients undergoing gynecological oncology surgery and was conducted as a single-center, double-arm, single-blinded randomized controlled trial at the Gold Coast University Hospital, Queensland, Australia. Participants were randomized into the VR intervention + care as usual (CAU) group (n = 39) and the CAU group (n = 41). Anxiety scores were assessed using a six-tier visual facial anxiety scale at baseline, after the intervention/CAU on the same day, and, several days up to weeks later, immediately before surgery. There was no significant difference in baseline anxiety scores, type of operation, or suspected cancer between the two groups. The VR intervention significantly reduced anxiety scores from baseline to preoperative assessment (p < 0.001). The median anxiety score in the VR intervention group decreased from 3 (interquartile range 2 to 5) at baseline to 2 (2 to 3) prior to surgery, while the control group's scores were 4 (2 to 5) and 4 (3 to 5), respectively. Multivariate analysis showed that group assignment was the sole outcome predictor, not age, type of procedure, or the time elapsed until surgery. Thus, VR exposure was effective in reducing perioperative anxiety in patients undergoing gynecological oncology surgery. The use of VR as a preparation tool may improve patient experience and contribute to better surgical outcomes, warranting further research into exploring the potential benefits of VR in other surgical specialties and its long-term impact on patient recovery.

Investigation of the effect of virtual reality distraction in patients undergoing mandibular periodontal surgery: A randomized controlled study

OBJECTIVE

This clinical study aimed to evaluate the effect of virtual reality (VR) technology on anxiety and pain levels in patients undergoing gingivectomy and gingivoplasty procedures.

MATERIALS AND METHODS

The patients were randomized into test (surgery with VR glasses) and control (surgery without VR glasses) groups. Before the surgery, the anxiety level was measured using the modified dental anxiety scale (MDAS), and anticipated pain (AP) was measured by a visual analog scale (VAS). Immediately after the surgery, the pain and discomfort associated with the surgery (VASP), procedure time (T), and time perception (TP) were evaluated. The patients in the test group were requested to assess the immersion (VASI), satisfaction (VASS), perception of reduced anxiety (VASA), and perceived control (VASC). One week after surgery, MDAS was applied to all patients.

RESULTS

This trial was conducted with 41 female and 17 male subjects with a mean age of 29.69 ± 12.32. There were no significant differences between the groups in terms of age, sex, preoperative MDAS, or AP. After surgery, MDAS, VASP, T, and TP failed to differ significantly between the groups. The subject age was positively correlated with VASI, VASS, VASA, and VASC (r = 0.60, p = 0.00; r = 0.44, p = 0.02; r = 0.46, p = 0.02; r = 0.50, p = 0.01, respectively) and negatively correlated with VASP (r = 0.47, p = 0.04).

CONCLUSIONS

VR application did not affect anxiety and pain levels in patients undergoing periodontal surgery. More studies are needed to evaluate VR distraction in periodontal surgeries with diverse age samples and video options.

CLINICAL SIGNIFICANCE

VR does not affect anxiety and pain levels during gingivectomy and gingivoplasty surgeries in the young adult population. It should be evaluated in older age groups. Trial registration ClinicalTrials.gov Identifier: NCT06092177.

Application of immersive virtual reality in the training of wheelchair boxers: evaluation of exercise intensity and users experience additional load- a pilot exploratory study

BACKGROUND

Over the last few years, there has been a growing interest in workout apps and active virtual reality video games (AVRGs), which provide entertainment and enable users to undertake various forms of physical activity (PA) at home. Presumably, these types of exercises can be particularly useful for people with physical disabilities, who experience problems with access to sports and leisure facilities due to architectural and communication barriers. However, it is interesting whether the intensity of PA in VR is high enough to provide users with health benefits, as it is mainly based on arm movements.

OBJECTIVE

The main aim of the study was to evaluate the intensity of physical exercise of wheelchair boxers during a boxing training session using the FitXR app in immersive VR in light of health-related PA recommendations. The effect of Velcro-fastened hand-held weights (HHWs) on the intensity of PA undertaken by people in VR was also examined, and the attractiveness of virtual exercise were assessed in the opinion of users.

METHODS

PA intensity was evaluated using a heart rate monitor based on the percentage of maximal heart rate (% HRmax) and the Borg's rating of perceived exertion (RPE 6-20). The attractiveness perceived during exercise by users were evaluated using the Physical Activity Enjoyment Scale (PACES 1-7 scale).

RESULTS

The study shows that the exercise intensity of the athletes during wheelchair boxing training in VR is at a beneficial moderate level for health (HRave=68.98% HRmax). The use of HHWs (0.5 kg) does not significantly increase the PA intensity of the individuals during virtual exercise. Users with disabilities highly rated the attractiveness (6.32 ± 0.79 points) of PA during virtual boxing training.

CONCLUSIONS

Boxing exercises in VR can be an attractive and health-related form of PA for wheelchair boxers and a supplement to their conventional training.

Virtual reality-guided mindfulness for chronic pain in cancer survivors: protocol for the virtual mind study-a single-group feasibility trial

Background

Chronic cancer-related pain (CRP) can have a significant negative impact on quality of life. Mindfulness is hypothesized to mitigate chronic CRP by regulating both physical and emotional resistance to pain. In recent years, there has been interest in the use of virtual reality (VR) to deliver mindfulness meditation. VR provides an immersive and engaging environment, which may enhance one's focused attention to present-moment experiences, potentially making mindfulness less effortful and more efficacious for individuals with chronic pain. There has been little research in this area for people with a history of cancer.

Objective

The aim of this mixed methods study is to evaluate the feasibility of a VR-guided mindfulness (VRGM) intervention offered to adult cancer survivors with chronic CRP.

Methods

This mixed methods feasibility study will employ a single-arm, pretest-posttest design with semistructured interviews. In total, 15 cancer survivors will be enrolled in a 6-week home-based intervention that consists of 10-15 min of daily VRGM practice. The primary outcome is feasibility as assessed by accrual rates, retention in the study, intervention adherence, questionnaire completion, and side effect rates. Participants will be assessed on psychosocial outcome measures (i.e., pain, sleep, depressive and anxiety symptoms, fatigue, quality of life, and mindfulness) before and after the intervention, and 6 weeks post intervention (follow-up). Changes in pain will be described in relation to levels of immersion and presence in the virtual environment, trait mindfulness, and amount of VRGM practice. Qualitative information will provide subjective detail on participants' experience with VRGM to complement quantitative data. This study has been approved by the Health Research Ethics Board of Alberta Cancer Committee (HREBA.CC-20-0411).

Conclusions

This novel intervention provides a potential alternative treatment to pharmacological pain management. Results from this study may inform future larger VGRM trials for chronic CRP to help reduce suffering in people with cancer. Study findings will be disseminated through open access publications, traditional conference presentations, professional cancer organizations, and social media platforms.

The effect of virtual reality on pain, fear and emotional appearance during blood draw in pediatric patients at the hematology-oncology outpatient clinic: A randomized controlled study

OBJECTIVE

Invasive attempts can be very painful and stressful for pediatric patients. Virtual Reality (VR) can be used to distract patients undergoing such procedures in pediatric hematology oncology patients.

METHODS

A parallel trial design approach was adopted for this randomized controlled trial, guided by the CONSORT checklist. The study sample (n = 69) was divided into a VR group (n = 34) and a control group (n = 35) using stratified randomization. For the blood draw attempt, no distraction method was applied to the control group, while the children in the VR group were distracted from the procedure with the Epic Roller Coasters VR application. The primary variable assessed was pain, while secondary variables were fear and emotional appearance. The scores of emotional appearance, fear, and pain were compared with a Mann-Whitney U Test.

RESULTS

The pre-procedure emotional appearance score was 11.3 ± 4.3 in the VR group and 11.0 ± 5.0 in the control group, and the post-procedure score was 6.5 ± 3.3 in the VR group and 11.8 ± 5.3 in the control group, indicating a difference in emotional appearance after the procedure. VR group had lower negative emotional appearance, lower pain, and lower fear scores after procedure compared to the control group.

CONCLUSION

VR can be considered an effective approach to reducing the negative emotional appearance and for relieving pain and fear in children aged 4-12 years undergoing blood draw procedures in pediatric hematology and oncology outpatient unit (ClinicalTrials.gov: NCT05675358).

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.

Ethical Challenges of Virtual Reality Technology Interventions for the Vulnerabilities of Patients With Chronic Pain: Exploration of Technician Responsibility

Chronic pain, a common disease, is a crucial global public health concern. Approximately 20% of the worldwide population is affected by chronic pain, which accounts for 15% to 20% of hospital visits. In Canada, approximately 7.6 million people-or 1 in 5 people-experience chronic pain. Among this population, 60% has either lost their employment or experienced a reduction in income as a result of their pain. The proportion of older people (aged ≥65 years) with chronic pain is high, comprising one-third of the total older population. In addition, the causes of chronic pain and its cures are unknown, and treatment is limited by these unknowns and the dangers of opioids. These essential factors make patients with chronic pain one of the most vulnerable populations. The use of emerging virtual reality (VR) technology as an intervention for chronic pain has consistently demonstrated early effectiveness and has been termed as a "nonpharmacological analgesic." Nevertheless, we must remain vigilant about the potential ethical risks of VR interventions, as inappropriate VR interventions may exacerbate the vulnerabilities of patients. Currently, a central challenge for VR developers is the ambiguity of patient vulnerability and the unpredictability of ethical dilemmas. Therefore, our paper focused on the vulnerability and ethical dilemmas faced by patients with chronic pain in VR interventions. Through an experience-based, prospective ethical examination, we have identified both existing and potential new vulnerabilities and specific manifestations that patients with chronic pain may encounter in VR interventions. Our aim was to highlight the ethical risks that may be present in VR interventions. On one hand, this can help raise awareness among technology developers regarding the vulnerabilities of patients with chronic pain and mitigate technological ethical risks. In addition, it can assist technology developers in determining the priorities for VR technology interventions. These efforts collectively lay a solid foundation for the comprehensive realization of responsible VR technology interventions.

Immersive Virtual Reality Fitness Games to Improve Recovery After Colorectal Surgery: A Randomized Single Blind Controlled Pilot Trial

Introduction: Early mobilization after surgery is crucial for reducing postoperative complications and restoring patients' fitness and ability to care for themselves. Immersive, activity-promoting fitness games in virtual reality (VR) can be used as a low-cost motivational adjunct to standard physiotherapy to promote recovery after surgery. In addition, they have potentially positive effects on mood and well-being, which are often compromised after colorectal surgery. The purpose of this pilot study was to evaluate the feasibility and clinical outcomes of a VR-based intervention that provides additional mobilization. Methods: Patients undergoing curative surgery for colorectal cancer were randomly assigned to an intervention group or a control group. Participants in the intervention group (VR group) received daily bedside fitness exercises using immersive, activity-promoting, virtual reality fitness games in addition to standard care during their postoperative hospital stay. Results: A total of 62 patients were randomized. The feasibility outcomes were in line with the predefined goals. In the VR group, an improvement in overall mood (+0.76 points; 95% confidence interval [CI] 0.39 to 1.12; P < 0.001) and a shift toward positive feelings were observed. The median length of hospital stay was 7.0 days in the VR group compared with 9.0 days in the control group, but the difference (2.0 days) did not reach statistical significance (95% CI -0.0001 to 3.00; P = 0.076). Surgical outcomes, health status, and measures of distress did not differ between groups. Conclusions: The study demonstrated the feasibility of a VR intervention that improved overall mood and showed a desirable effect on feelings and length of hospital stay after colorectal surgery. The results should stimulate further research investigating the potential of VR as an adjunct to physiotherapy to enhance mobilization after surgery.

Network meta-analysis of randomized controlled trials comparing the effectiveness of different treatments in reducing amniocentesis-associated pain and anxiety

OBJECTIVE

This network meta-analysis compared different methods to determine which is most efficient at lowering pain and anxiety in women undergoing amniocentesis.

METHOD

We looked through all published randomized controlled trials in the databases PubMed, Scopus, Web of Science, Cochrane, and EM base. Anxiety and pain were the predominant results. We used the R software version 4.2.1 to analyze the data.

RESULTS

We included a total of 20 studies, with sample sizes ranging from 60 to 570. Virtual reality was the most effective strategy for lowering pain during AC [MD = -1.30, 95% CI (-2.11, -0.49)]. In addition, paracetamol use was the most successful approach for lowering pain following AC [MD = -1.68, 95% CI (-1.99, -1.37)]. The use of H7 acupressure, however, was the strategy that significantly reduced anxiety following AC [SMD = -15.46, 95% CI (-17.77, -13.15)].

CONCLUSION

The most effective method for reducing pain is the combination of virtual reality with paracetamol. Whereas, the most effective way to reduce anxiety is to combine an ice gel pack with H7 acupressure before applying AC.

Global Scientific Trends in Virtual Reality for Pain Treatment From 2000 to 2022: Bibliometric Analysis

Background

Virtual reality (VR) is a computer simulation technique that has been increasingly applied in pain management over the past 2 decades.

Objective

In this study, we used bibliometrics to explore the literature on VR and pain control, with the aim of identifying research progress and predicting future research hot spots.

Methods

We extracted literature on VR and pain control published between 2000 and 2022 from the Web of Science Core Collections and conducted bibliometric analyses. We analyzed the publication and citation trends in the past 2 decades, as well as publication and citation analyses of different countries, institutions, journals, and authors. For references, we conducted cocitation and burst analyses. For keywords, we conducted co-occurrence, clustering, timeline view, and citation burst analyses.

Results

Based on 1176 publications, we found that there was a continuous increase in publication and citation volumes, especially in the last 5 years. The United States was the most representative country, and the University of Washington was the most representative institution, with both having the most publications and citations. The most popular journal in this field was Burns, and Hoffman HG was the most productive author, leading many studies on patients with burn pain. The reference with the most citation burst was a study on the verification of new hardware in pain control. The keywords with the highest citation bursts related to various situations of pain such as "burn pain," "wound care," "low back pain," and "phantom limb."

Conclusions

VR has been applied in various clinical situations for pain management, among which burns and pediatric surgery have achieved satisfactory results. We infer that VR will be extended to more clinical pain situations in the future, such as pain control in wound care, low back pain, and phantom limb pain. New research hot spots will include the development of software and hardware to improve the immersive experience of VR for pain control. However, our work was based solely on English literature from the Web of Science database. For future studies, we recommend that researchers explore literature from multiple databases to enhance the scope of their research.

Bibliometric Analysis of Research Articles on Virtual Reality in the Field of Pain Medicine Published from 1993 to 2022

Purpose

This study aims to analyze global and regional (China, Japan, and South Korea) research on virtual reality (VR) in the field of pain medicine over the past 30 years. Specifically, we quantify VR-related publications, examine the distribution of research topics on chronic and acute pain, and identify trends and future directions.

Methods

The Web of Science Core Collection (WoSCC) database was used for bibliometric analysis. This study included articles written in English between 1993 and 2022. The search strategy used predefined terms related to VR and pain. Based on the articles' titles and abstracts, two pain physicians independently reviewed and classified them as acute or chronic pain. Quantitative data on countries, institutions, journals, and research categories were analyzed. VOSviewer software was used for keyword mapping and clustering.

Results

We analyzed 808 VR-related articles on pain medicine. Over the past three decades, the number of publications in this field has increased steadily. The United States of America (n = 259) had the highest number of publications. Moreover, China (n = 42), Japan (n = 18), and South Korea (n = 24) also contributed continuously. Acute and chronic pain research accounted for 44.2% and 37.9% of the articles, respectively. The most common acute pain topic was procedure-related (n = 129, 16.0%), whereas the most common chronic pain topic was neuropathic (n = 104, 12.9%). Keywords clustered around neuroscience, pediatric pain management, and chronic pain management.

Conclusion

Our study revealed academic achievements and growing interest in VR-related research in pain medicine. Researchers worldwide have shown balanced interest in applying VR technology to acute and chronic pain, with specific contributions from China, Japan, and South Korea. Harnessing VR technology is promising for improving pain management and enhancing patients' quality of life in the field of pain medicine.

Online Chair Yoga and Digital Learning for Rural Underserved Older Adults at Risk for Alzheimer's Disease and Related Dementias

OBJECTIVES

We evaluated the feasibility and preliminary efficacy of a home-based online chair yoga (OCY) program for racially and ethnically diverse rural community-dwelling older adults.

METHODS

We randomly assigned participants to OCY or a computer brain game (CBG). After a computer literacy training led by high school students, participants engaged in remotely supervised OCY or CBG in twice-weekly 45-minute sessions for 12 weeks. Outcome data (pain interference, cognitive function, mobility, computer skills) were collected at baseline, post-intervention, and 3-month follow-up.

RESULTS

A total of 32 eligible residents with mean age of 71 years participated in this intervention study. The interventions were feasible (100% recruitment rate, 96.8% retention rate, 100% safety rate). There were significant improvements in pain interference, cognitive function, mobility, and computer skills from baseline to follow-up among participants in both OCY and CBG but no significant differences in outcomes between groups.

CONCLUSIONS

Preliminary results indicated that the CBG was as effective as online OCY in clinical outcomes in these participants. However, this should be confirmed in future studies.

CLINICAL IMPLICATIONS

This telehealth-based intervention is feasible for older adults in rural and digitally underserved communities and could provide a strategy for delivering health-promoting interventions for home-bound older adults at risk for Alzheimer's disease and related dementias (ADRD) and connect caregivers to online resources.

Rehabilitation Supported by Immersive Virtual Reality for Adults With Communication Disorders: Semistructured Interviews and Usability Survey Study

BACKGROUND

Individuals who have acquired communication disorders often struggle to transfer the skills they learn during therapy sessions to real-life situations. Immersive virtual reality (VR) technology has the potential to create realistic communication environments that can be used both in clinical settings and for practice at home by individuals with communication disorders.

OBJECTIVE

This research aims to enhance our understanding of the acceptance, usefulness, and usability of a VR application (SIM:Kitchen), designed for communication rehabilitation. Additionally, this research aims to identify the perceived barriers and benefits of using VR technology from the perspective of individuals with acquired communication disorders.

METHODS

Semistructured interviews and usability surveys were conducted with 10 individuals with acquired neurogenic communication disorders aged 46-81 (mean 58, SD 9.57) years after trialing an immersive VR application. The audio-recorded interviews were transcribed and analyzed to identify themes.

RESULTS

The quantitative data regarding the usability of the system associated with participants' immersion experience in the VR application were promising. Findings from semistructured interviews are discussed across five key thematic areas including (1) participant's attitude toward VR, (2) perceived usefulness of the VR system, (3) perceived ease of use of the VR system, (4) their willingness to continue using VR, and (5) the factors they perceived as challenges or facilitators to adopting this VR technology.

CONCLUSIONS

Overall, participants in this study found the VR experience to be enjoyable and were impressed by the realism of the VR application designed for communication rehabilitation. This study highlighted personally relevant, immersive VR interventions with different levels of task difficulty that could enhance technology uptake in the context of communication rehabilitation. However, it is essential that VR hand controller technology is refined to be more naturalistic in movement and able to accommodate user capabilities.

The Effect of Virtual Glasses Application on Pain and Anxiety During Episiotomy Repair: Randomized Controlled Trial

BACKGROUND

In the literature, the efficacy of virtual glasses on acute pain and anxiety has been investigated, and no study has been found on its effect on pain and anxiety during episiotomy repair.

AIMS

To determine the efficacy of virtual glasses application in pain and anxiety during episiotomy repair.

DESIGN

Randomized controlled trial design was used.

PARTICIPANTS

The study included 120 women who were primiparous and pregnant: 40 in the control group and 80 in the experimental groups (virtual glasses and skin to skin contact).

METHODS

Data were collected using Descriptive Information Form, the Visual Analog Scale (VAS), and the State Anxiety Inventory. In experimental groups, virtual glasses and skin to skin contact were applied during episio tomy repair by the researcher, and they were not applied to the control group. The VAS and State Anxiety Inventory were used to assess pain and anxiety in all groups before and after application. In the statistical analysis of the data, the SPSS 23.0 packa ge program was used. In all tests, p < .005 wa s considered statistically significant.

RESULTS

Immediately post intervention, the women in the experimental groups had significantly decreased anxiety and pain during episiotomy repair. Comparing three methods, the virtual glasses significantly reduced anxiety and pain after application (p < .05).

CONCLUSIONS

Virtual glasses are more effective than skin to skin contact and control methods in decreasing pain and reducing anxiety during episiotomy repair. Additionally, virtual glasses may reduce the need for pharmacological medication due to this reduction in pain and anxiety during episiotomy repair.

Dominance-submissiveness cues modulate pain threshold for mechanical pressure

Acute pain sensation is an inherently negative but adaptive experience; however, research on pain sensitivity shows that simple contextual cues can effectively attenuate the pain. In this study, we sought to investigate how dominance cues, manipulated as vertical spatial (i.e., height) distance between participants and experimenter, affect participants' pain sensitivity. Positioning participants in a spatially higher position relative to the experimenter was aimed to induce a feeling of dominance in participants. Conversely, a feeling of submissiveness was induced by placing the experimenter in a spatially higher position. In addition, we examined the role of dominance cues with respect to participants' and experimenters' gender. Two separate studies were conducted-Study 1 with a male experimenter measuring pain threshold in female and male participants (N = 137), and Study 2 with a female experimenter conducting pain measurement in a new sample of female and male participants (N = 122). The results of both studies demonstrated that participants in a dominant position reported a higher pain threshold relative to participants in a submissive position. Male participants had a higher pain threshold in both studies; however, Study 1 revealed a significant interaction of dominance manipulation and participant's gender, with the effect of dominance cues being larger in men.

Creating Custom Immersive 360-Degree Videos for Use in Clinical and Nonclinical Settings: Tutorial

The use of virtual reality (VR) stimulation in clinical settings has increased in recent years. In particular, there has been increasing interest in the use of VR stimulation for a variety of purposes, including medical training, pain therapy, and relaxation. Unfortunately, there is still a limited amount of real-world 360-degree content that is both available and suitable for these applications. Therefore, this tutorial paper describes a pipeline for the creation of custom VR content. It covers the planning and designing of content; the selection of appropriate equipment; the creation and processing of footage; and the deployment, visualization, and evaluation of the VR experience. This paper aims to provide a set of guidelines, based on first-hand experience, that readers can use to help create their own 360-degree videos. By discussing and elaborating upon the challenges associated with making 360-degree content, this tutorial can help researchers and health care professionals anticipate and avoid common pitfalls during their own content creation process.

Pain and anxiety in patients with breast cancer treated with morphine versus tramal with virtual reality

The treatment of pain and anxiety in cancer patients includes both pharmaceutical and non-pharmacological approaches. The researchers of this study aimed to compare the effectiveness of morphine versus Tramal with virtual reality therapy (VR) in reducing pain and anxiety in female patients with breast cancer. The sample was composed of 80 women with breast cancer who where treated at a specialized cancer center in Jordan. A quasi-experimental design was used in the study intervention. When used with VR, the tramal analgesics did not differe significactly from the effect of morphine in reducing the pain and anxiety. However, both groups had a significant drop in the level of pain and anxiety. When combined with VR, the use of weak opioids such as Tramal will have nearly the same effect as strong opioids such as Morphine in reducing pain and anxiety in breast cancer patients.

Virtual Reality as Pain Relief in Burn Care: A Pilot Randomized Controlled Trial on the Effectiveness on Pain During Multiple Dressing Changes

This pilot Randomized Controlled Trial (RCT) aimed to investigate the effectiveness of Virtual Reality (VR)-distraction on pain during multiple Wound Dressing Changes (WDCs). Furthermore, associations between demographic, clinical, and psychological factors and pain during WDC were determined. Participants were randomized to either the VR-condition or Care As Usual (CAU)-condition. Both groups received standard wound care and pain medication. The VR-group additionally received VR-distraction. The primary outcome measure was pain intensity (VAT 0-10). Secondary outcome measures were pain medication (Fentanyl spray and/or Piritramide) and satisfaction with WDC (VAT 0-10). Only 38 patients (VR-group: n = 21; CAU-group: n = 17) of the 128 intended patients were included during the study period due to several limitations (strict exclusion criteria and restrictions of the VR-equipment). No significant differences were found between both groups on pain intensity and medication. Both groups were also equally satisfied with WDC. Age showed a significant negative correlation with pain during WDC. In view of the small sample size, this study has restricted power and should be considered a pilot. Nevertheless, a RCT with between-subjects design across multiple WDCs was feasible and, given the speed of VR-developments, we expect larger, better powered RCTs to be possible in the near future, for which our experiences and recommendations are relevant.

Sensory stimulations potentializing digital therapeutics pain control

For the past two decades, using Digital Therapeutics (DTx) to counter painful symptoms has emerged as a novel pain relief strategy. Several studies report that DTx significantly diminish pain while compensating for the limitations of pharmacological analgesics (e.g., addiction, side effects). Virtual reality (VR) is a major component of the most effective DTx for pain reduction. Notably, various stimuli (e.g., auditory, visual) appear to be frequently associated with VR in DTx. This review aims to compare the hypoalgesic power of specific stimuli with or without a VR environment. First, this review will briefly describe VR technology and known elements related to its hypoalgesic effect. Second, it will non-exhaustively list various stimuli known to have a hypoalgesic effect on pain independent of the immersive environment. Finally, this review will focus on studies that investigate a possible potentialized effect on pain reduction of these stimuli in a VR environment.

Effectiveness of non-immersive virtual reality in the management of procedure-related pain in preschool children: a randomized clinical trial

The objective of this study is to assess the effectiveness of non-immersive virtual reality as a pain-distraction measure in children between the ages of 3 and 5 years undergoing painful injection procedures in an outpatient setting. We carried out a randomized, unmasked clinical trial in children undergoing venipuncture or intramuscular injection procedures. Patients were randomized to a distraction virtual reality video or standard care. After the procedure, three independent observers (parents, researchers, nursing staff) rated pain on the LLANTO pain scale. We recruited 122 subjects, half of which were randomized to virtual reality. The median age was of approximately 60 months (IQR: 15 months), and the sample was balanced with regard to sex. There were significant differences in LLANTO scales scores between the VR subjects and controls of - 3.34 (95% CI - 4.15; - 2.54), - 3.02 (95% CI - 3.90; - 2.14), and - 2.98 (95% CI - 3.87; - 2.09), as rated by parents, researchers, and nursing staff, respectively. Agreement between raters was high for all three types of observers, with Cohen Kappas over 0.79 in all cases. Bivariate analysis showed reductions in the risk of obtaining higher scores in the LLANTO scale. Linear regression models showed a reduction of approximately 3 points in the scale, regardless of the type of observer. These models were adjusted for sex, age, kind of procedure, use of prior analgesia, and recruitment center.

CONCLUSIONS

Non-immersive virtual reality is an effective adjunctive therapy for the reduction of pain in children undergoing painful injection procedures in an outpatient setting. This strategy may be used to improve the quality of care in pediatric outpatient services.

TRIAL REGISTRATION

ClinicalTrials.gov Identifier: NCT03985930 (Registered June 14, 2019).

WHAT IS KNOWN

•The use of immersive virtual reality (VR) has been described as an effective adjunctive distraction method during painful procedures in children over 5 years.

WHAT IS NEW

•The utility of non-immersive VR in children below that age is not yet clear. This randomized clinical trial comparing non-immersive VR vs. standard care showed an average reduction of three points in the LLANTO pain scale favoring non-immersive VR. Non-immersive VR is an effective and inexpensive non-pharmacological technique that reduces fear and pain in pediatric patients.

The use of virtual reality hypnosis for prostate cancer patients during transperineal biopsy/gold seed implantation: A needs assessment study

BACKGROUND

Patients having radiation therapy treatment to the prostate may require invasive preparation procedures under local anesthesia (LA), such as the insertion of gold seeds into the prostate or targeted biopsies. These procedures can induce pain and anxiety for some patients. Virtual Reality Hypnosis (VRH) is the combination of a 360-degree video display with audio and mental guides for relaxation and distraction during medical procedures. The objective of this research was to assess the level of patient interest in the use of VRH during gold seed insertion and biopsy, and to identify a subset of patients that would be most likely to benefit from the use of VRH.

METHODS

This single arm, prospective pilot study included patients who were receiving biopsy and/or gold seed insertion using a 2-step LA procedure. Participants were asked to complete a questionnaire about their level of knowledge and interest in VRH before and after their procedure. At the same time, pain and anxiety levels were collected before and after the procedure, as well as during each LA step and at the mid-seed drop/biopsy core extraction. A visual analogue scale for pain and the National Comprehensive Cancer Network's Distress Thermometer were used to verbally rate pain and distress respectively. Descriptive statistics and Pearson's correlation coefficient were calculated for all variables of interest.

RESULTS

24 patients were recruited and 1 had their procedure cancelled, so a total of 23 patients completed this study. 74% of patients (n=23) agreed to try VRH before their procedures, whereas 65% of patients (n=23) were willing to try VRH after the procedure. Pain scores were highest at deep LA injection (mean= 5.48, SD= 2.56) and distress scores were also highest at deep LA injection (mean= 4.28, SD= 2.92). After the procedure, 83% of participants with pain scores above the mean at deep LA injection and 80% with anxiety scores above the mean at deep LA injection agreed that they would be willing to try VRH.

CONCLUSIONS

Patients with higher pain and distress scores had more interest in trying VRH with the standard LA for gold seed insertion/biopsy procedures. Patients with a history of lower pain tolerance or who express having experienced high levels of pain during previous biopsies will be the target population for using VRH in future trials to determine feasibility and effectiveness.

Non-Pharmacological Interventions for Pain Management in Hemodialysis: A Narrative Review

This narrative review aims to summarize non-pharmacological interventions for pain management in hemodialysis patients, assessing their potential benefits and limitations in enhancing patient well-being and quality of life. We reviewed the current literature on five primary non-pharmacological interventions: acupuncture, cognitive behavioral therapy, relaxation techniques, virtual reality, and alternative methods such as transcutaneous electrical nerve stimulation, music therapy, and aromatherapy. We analyzed the evidence regarding their effectiveness, feasibility, and optimal implementation strategies. The existing evidence supports the potential benefits of these interventions in managing pain and improving the well-being of hemodialysis patients. However, further high-quality research is needed to confirm their effectiveness, establish implementation best practices, and assess their long-term impact on patient outcomes. Non-pharmacological interventions hold promise for pain management in hemodialysis patients. Additional research is required to optimize these interventions and validate their effectiveness, contributing to comprehensive pain management strategies for this vulnerable patient population.
