Despite optimal treatment with medication, people with Parkinson's disease (PD) still experience symptoms and secondary complications. Physiotherapy has long been recognized as one of the leading treatments in PD for slowing progression of the disease and retaining a higher quality of life for longer. Physiotherapy includes, among other things, training motor functions e.g., gait, balance and strength training and encourages physical activity. Exercise is an important part of healthy living for everyone, but for people with PD, exercise is medicine. Studies even suggest that exercise may slow down disease progression. Another way of improving PD motor symptoms, such as festination and freezing of gait (FOG), in a more direct way is by sensory cueing. Cueing is defined as the application of spatial or temporal external stimuli to help initiate, or facilitate gait, and can be presented as acoustic, visual, or tactile stimuli. It has been well known for many years that sensory cueing is effective and there has been extensive research on the topic. Cue X is a new product developed by Strolll Limited (www.strolll.co) that applies the existing proven principles of exercise and sensory cueing for PD onto augmented-reality (AR) headsets implemented in two modules: movement training and movement assistance. The movement training module is designed to train gait and balance in a gamified manner to maximize training compliance. With this clinical feasibility study, the investigators want to examine the feasibility and potential efficacy of the Cue X movement training module to train gait and balance of people with PD in their home environment.
The primary objective of this clinical feasibility study in people with PD is to evaluate the feasibility and potential efficacy of home-based gamified AR gait-and-balance exercises with Cue X. Secondary objectives of this study are to validate the gait-modifying effects of Cue X AR cueing and to quantify the test-retest reliability and concurrent validity of (clinical) outcome measures of gait and balance, as derived from AR headset data. With these primary and secondary objectives, the study will give insight into 1) the feasibility and potential efficacy of Cue X for home-based gamified AR gait-and-balance exercises, 2) the most effective type of AR cueing and 3) the best parameters for feedback, reporting and sample-size calculations for a subsequent effect study with Cue X. Furthermore, the study will inform about the best AR headset for these purposes.

The Cue X movement training module includes several games that can be performed in someone's home environment. The games are designed based on known physiotherapy guidelines and evidence for improving motor symptoms for people with PD and delivered in AR. Some of the games also have integrated cueing to allow people with more severe mobility impairments to participate. Feedback of performance can be given using the movement data of the AR headsets.

System Usability Scale (SUS) [Usability]
A 10-item questionnaire to measure usability of the Cue X training module, answered on a 5 point Likert scale (1 strongly disagree - 5 strongly agree). Minimum - maximum score: 10 - 50. Higher scores imply better usability of the Cue X software.
Time frame: After 6-week training
Number of adverse events [safety]
To measure safety of the Cue X training module
Time frame: During 6-week training
Side effects as reported by participants [safety]
To measure safety of the Cue X training module
Time frame: During 6-week training
Adherence to the training programme
Actual exercise time as a percentage of prescribed exercise time. The prescribed exercise time is 30 minutes, 5 days a week.
Time frame: During 6-week training
Patient-reported outcome measures (PROMs)
An example is quality of life as measured by the Parkinson's Disease Questionnaire (PDQ-39). This questionnaire assesses how often people with Parkinson's experience difficulties across 8 dimensions of daily living, among which quality of life. Higher scores on one of the dimensions indicate worse well-being on that specific dimension.
Time frame: Change between pre-, mid- and post-training measure (over a period of 12 weeks, which includes 6 weeks waiting list and 6-week intervention)
Patient-reported experience measures (PREMs)
Perceived effectiveness of the Cue X training programme through Likert scale reporting and semi-structured interview questions during weekly phone calls and a post-intervention interview.
Time frame: After 6-week training
Mini Balance Evaluation Systems Test (Mini-BESTest) [Gait-and-balance outcome measures]
To measure balance and postural control. Minimum - maximum score: 0 - 28. Higher scores indicate better balance and postural control.

Timed Up-and-Go test (TUG) [Gait-and-balance outcome measures]
To measure functional gait. Higher scores indicate worse functional gait.
Time frame: Change between pre-, mid- and post-training measure (over a period of 12 weeks, which includes 6 weeks waiting list and 6-week intervention)
Lindop Parkinson's Physiotherapy Assessment Scale (LPPAS) [Gait-and-balance outcome measures]
