Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will attend 4 x 30-minute individual face-to-face intervention sessions over 2 weeks in a clinical environment. For ~15 minutes at the end of each intervention session, participants will use a Meta Quest 3 virtual reality headset to view a 3-dimensional model of their upper limbs while in a virtual environment and, using a custom-designed software application, be able to manipulate the size, transparency, and colour of their (virtual) affected limb, according to their individual preferences. Once the appearance of the virtual limb has been adjusted to their satisfaction, participants will spend 5 minutes viewing and attending to the (visually altered) virtual limb under the guidance of a New Zealand registered specialist pain physiotherapist. During this time they will be asked by the physiotherapist to perform simple functional movements of their affected hand and/or arm, which will be reflected by the virtual limb (e.g. making a fist). These movements will be individually tailored for each participant by the physiotherapist. A session attendance checklist will be used to monitor adherence.
