A VR-MVF system was developed and used for the treatment of CRPS at the Okayama University Hospital. Preliminary results from applying this system in patients showed that VR-MVF therapy may be plausible for CRPS treatment. The effects of VR-MVF therapy, however, may be enhanced by increasing the frequency of treatments. Thus, a remote personal VR-MVF system was designed for future implementation, and a prototype personal VR-MVF system was developed. Patient evaluation of the prototype system by the PQ test shows the feasibility of our VR system for CRPS treatment.

Lower Limb Pain

BACKGROUND Complex Regional Pain Syndrome (CRPS) is a rare and severe chronic pain condition, with effective treatment options not established for many patients. The underlying pathophysiology is still unclear, but there is a growing appreciation for the role of central mechanisms which have formed the basis for brain based therapies such as transcranial magnetic stimulation and mirror visual feedback (MVF). MVF has been deployed in the treatment of Complex Regional Pain Syndrome (CRPS) using both conventional mirrors and virtual reality (VR). OBJECTIVE To further investigate the use of both conventional mirrors and virtual reality (VR) in the treatment of chronic unilateral upper limb Complex Regional Pain Syndrome (CRPS) patients. Virtual reality has the potential advantage of more flexible and more motivating tasks, as well as the option of tracking patient improvement through the use of movement data. METHODS We used the Virtual Embodiment Lab Open Source Mirror Feedback (VELOS MVF) module in a small pilot study We created a simple environment in immersive virtual reality; designed to be used with consumer virtual reality systems, which allowed left-to-right and right-to-left mirroring in the upper and lower limbs during a simple target-hitting task. We then tested the usability and efficacy of the system in a small sample of CRPS patients at a clinic. RESULTS Nine participants were able to use the system for four or five trials each. We did not find a statistically significant effect on participants’ self-reported average pain scores. No participants quit any trial due to cybersickness. CONCLUSIONS We propose that this module could be a useful starting point for modification and testing for other researchers. Next steps include adapting this module for at-home use, or for use with participants with lower-limb pain.

BACKGROUND Virtual reality-assisted physical therapy is a promising treatment for children with cerebral palsy. However, thus far, it has not been used for adult patients. OBJECTIVE The following case report examines the safety and feasibility of customized virtual reality interventions for an adult patient with cerebral palsy who was experiencing right sided pain, weakness, dystonias. METHODS This research included two phases of intervention, which were based on the principles of mirror visual feedback, occasionally termed “mirror box therapy.” The patient used self-report rating scales to monitor anxiety and depression levels, as well as provided verbal feedback regarding pain levels. RESULTS The treatments were well tolerated, and the patient reported improved function in the injured limb. However, the duration of pain relief was only 2–4 days between sessions, causing the patient to require ongoing in office virtual reality treatments. CONCLUSIONS The implications of these findings for the future treatment of such patients are discussed.
