Assessing perceptions to a virtual reality intervention to improve trunk control in Parkinson’s disease: a preliminary study
2023
Overview
Trunk control and postural instability remain critical markers of functional status in Parkinson’s Disease (PD). As pharmacological and invasive neuro-stimulation interventions provide only limited benefits for trunk and postural control, exercise-based interventions may provide the only effective path to improving functional outcomes for balance in PD. We describe the framework for a virtual reality (VR) graded exercise-based intervention focused on improving trunk mobility and control, including preliminary outcomes on perceptions and motion capabilities of individuals with PD. The study collected whole-body motion capture from 11 PD participants (8M, 3F; H&Y Stage I–III) as they performed tasks within a custom-designed set of VR therapies. Therapies involved static interactions (e.g., matching a cube sequence set to anthropometrically relevant locations to elicit specific trunk motions—
Matchality
), and more dynamic tasks (e.g., intercepting virtual fish jumping from a lake—
Fishality
, or a virtual session of dodgeball—
Dodgeality
). Participants were able to safely complete all tasks while performing trunk excursions requiring functionally relevant ranges of motion, and which altered across VR environment (

These results provide early safety, usability, and feasibility outcomes for VR interventions that require specific trunk excursions. Future work should confirm the effectiveness of VR interventions longitudinally on PD-specific trunk outcomes (e.g., trunk rigidity) and global balance/mobility measures associated with improved functional status.
