Virtual embodiment for improving range of motion in patients with movement-related shoulder pain: an experimental study.

BACKGROUND: Recent evidence supports the use of immersive virtual reality (VR) as a means of delivering bodily illusions that may have therapeutic potential for the treatment of musculoskeletal conditions. We wanted to investigate whether a single session of an embodiment-based immersive VR training program influences pain-free range of motion in patients with shoulder pain. METHODS: We designed a rehabilitation program based on developing ownership over a virtual body and then "exercising" the upper limb in immersive VR, while the real arm remains static. We then carried out a single-arm pre-post experiment in which 21 patients with movement-related musculoskeletal shoulder pain were exposed to the 15-min VR program and measured their active pain-free range of motion immediately before and afterwards. RESULTS: We found that shoulder abduction and hand-behind-back movements, but not shoulder flexion, were significantly and clinically improved post-intervention and that the level of improvement correlated with the level of embodiment. Following this one session, at 1-week follow-up the improvements were not maintained. CONCLUSIONS: Virtual embodiment may be a useful therapeutic tool to help improve range of motion in patients with movement-related shoulder pain in the short term, which in turn could expedite rehabilitation and recovery in these conditions.

VR for Pain Relief.

The present chapter explores how immersive virtual reality (VR) systems can be used for pain research and treatment. Pain is a universal, yet entirely subjective and multifaceted unpleasant experience. One of the earliest VR studies on pain highlighted the role of attention in pain modulation. However, the role of body representation in pain modulation has also been described as a crucial factor. Through virtual reality systems, it is possible to modulate both attention to pain and body representation. In this chapter, first we define how immersive VR can be used to create the illusion of being present in immersive VR environments and argue why VR can be an effective tool for distracting patients from acute pain. However, distraction seems to be less useful in chronic pain treatment. Chronic pain can be highly disabling and can significantly impact not only the sufferer's quality of life, but also their perceptions of the bodily self. Close neural connections between the body matrix and pain open a chance for influencing pain through bodily illusions. This chapter explores approaches to inducing body ownership illusions in VR and discusses how they have been applied in pain research. The present chapter also covers a set of practical indications and methodological caveats of immersive VR and solutions for overcoming them. Finally, we outline several promising future research directions and highlight several yet unexplored areas.

Altered bodily perceptions in chronic neuropathic pain conditions and implications for treatment using immersive virtual reality.

Chronic neuropathic pain is highly disabling and difficult to treat and manage. Patients with such conditions often report altered bodily perceptions that are thought to be associated with maladaptive structural and functional alterations in the somatosensory cortex. Manipulating these altered perceptions using body illusions in virtual reality is being investigated and may have positive clinical implications for the treatment of these conditions. Here, we have conducted a narrative review of the evidence for the types of bodily distortions associated with a variety of peripheral and central neuropathic pain conditions. In addition, we summarize the experimental and clinical studies that have explored embodiment and body transformation illusions in immersive virtual reality for neuropathic pain relief, which are thought to target these maladaptive changes, as well as suggesting directions for future research.

Manipulating the Perceived Shape and Color of a Virtual Limb Can Modulate Pain Responses.

Changes in body representation may affect pain perception. The effect of a distorted body image, such as the telescoping effect in amputee patients, on pain perception, is unclear. This study aimed to investigate whether distorting an embodied virtual arm in virtual reality (simulating the telescoping effect in amputees) modulated pain perception and anticipatory responses to pain in healthy participants. Twenty-seven right-handed participants were immersed in virtual reality and the virtual arm was shown with three different levels of distortion with a virtual threatening stimulus either approaching or contacting the virtual hand. We evaluated pain/discomfort ratings, ownership, and skin conductance responses (SCRs) after each condition. Viewing a distorted virtual arm enhances the SCR to a threatening event with respect to viewing a normal control arm, but when viewing a reddened-distorted virtual arm, SCR was comparatively reduced in response to the threat. There was a positive relationship between the level of ownership over the distorted and reddened-distorted virtual arms with the level of pain/discomfort, but not in the normal control arm. Contact with the threatening stimulus significantly enhances SCR and pain/discomfort, while reduced SCR and pain/discomfort were seen in the simulated-contact condition. These results provide further evidence of a bi-directional link between body image and pain perception.

Immersive Virtual Reality and Virtual Embodiment for Pain Relief.

A significant body of experimental evidence has demonstrated that it is possible to induce the illusion of ownership of a fake limb or even an entire fake body using multisensory correlations. Recently, immersive virtual reality has allowed users to experience the same sensations of ownership over a virtual body inside an immersive virtual environment, which in turn allows virtual reality users to have the feeling of being "embodied" in a virtual body. Using such virtual embodiment to manipulate body perception is starting to be extensively investigated and may have clinical implications for conditions that involve altered body image such as chronic pain. Here, we review experimental and clinical studies that have explored the manipulation of an embodied virtual body in immersive virtual reality for both experimental and clinical pain relief. We discuss the current state of the art, as well as the challenges faced by, and ideas for, future research. Finally, we explore the potentialities of using an embodied virtual body in immersive virtual reality in the field of neurorehabilitation, specifically in the field of pain.

Survey of patients' view on functional split of consultant psychiatrists.

BACKGROUND: The functional split model of consultant psychiatrist care for inpatients has been one of the major service redesign that has occurred in the NHS in the last decade. It is unclear if this new split model offers any advantages over the previous sectorised model of working. More recent evidence has suggested that patients, carers and professionals have varied views regarding the benefits of this model. This survey of patient's views on models of consultant working is the first in Scotland and we have attempted to include a large sample size. The results suggest that after providing sufficient information on both models, the majority of patients from various Scottish health boards have opted for the traditional sectorised model of working. METHOD: During a four week period consecutive patients across 4 health boards attending the General Adult consultant outpatient clinics and those who were admitted to their inpatient ward were offered a structured questionnaire regarding their views on the functional split versus traditional sectorised model. Space was provided for additional comments. The study used descriptive statistical measures for analysis of its results. Ethical approval was confirmed as not being required for this survey of local services. RESULTS: We had a response rate of 67%. A significant majority (76%) of service users across the four different health boards indicated a preference for the same consultant to manage their care irrespective of whether they were an inpatient or in the community (Chi-squared = 65, df = 1, p < 0.0001). In their unstructured comments patients often mentioned the value of the therapeutic relationship and trust in a single consultant psychiatrist. CONCLUSIONS: Our survey suggests that most patients prefer the traditional model where they see a single consultant throughout their journey of care. The views of patients should be sought as much as possible and should be taken into account when considering the best way to organize psychiatric services.

Reflections on facilitated discharge from a mental health service.

OBJECTIVE: The aim of this paper is to review research evidence and describe our experience of facilitated discharge from mental health services to primary care. METHOD: A literature review of facilitated discharge was conducted. In addition, the clinical characteristics of 21 discharged and 21 non-discharged patients from one shared care service were compared in a retrospective file review. Thirty-one patients in another facilitated discharge program were surveyed. RESULTS: Discharged patients had a higher level of function. There was a trend towards discharged patients being female and employed with less chronic illness, involuntary treatment, behavioural symptoms, depot medication, triage contact, service contact with family, and more mood disorder. Of the 10 survey respondents, 60% reported feeling better compared with their last service contact, 70% felt not having contact was a good thing and most saw their doctors regularly and reported a good relationship. CONCLUSIONS: There was a trend towards more stable patients being discharged and it appeared that they responded positively to this, without a clear indication of which factors best determine suitability for discharge. Consequently, we elected to incorporate discharge planning processes as a core function of case management and increase shared care with the primary care sector.

Teachers' perceptions of health education practice in Northern Ireland: reported differences between policy and non-policy holding schools

It is generally accepted that schools should devote resources to developing and disseminating a health education policy, yet there is little empirical evidence to establish the value of policy in this context. This study examined teachers' perceptions of health education practice in policy and non-policy holding schools. A questionnaire measuring aspects of health education practice was issued to a random sample of schools. This consisted of 276 primary and 119 post-primary schools. In this cross-sectional study, significant differences in teachers' evaluations were found between policy and non-policy holding schools. It was evident that the presence of a health education policy was associated with higher ratings of health education practice. This evidence suggests that policy has intrinsic value in terms of health education practice. The development and dissemination of policy documents were also examined to assess the workload involved.
