Steps Against the Burden of Parkinson's Disease
Sponsor: The University of New South Wales
Summary
Parkinson's Disease Treadmill Training RCT Summary Parkinson's disease (PD) affects over 10 million people globally. Despite optimal pharmacological treatment, approximately 70% of individuals experience unstable gait and falls, leading to loss of confidence, social isolation, fractures, and frequent hospitalisations. Treadmill training-especially when augmented by mechanical or virtual-reality perturbations-has shown promise in improving gait and reducing fall risk. However, the mechanisms underlying these benefits remain poorly understood, limiting the ability to personalise interventions effectively. This randomised controlled trial (RCT) forms part of the broader Steps Against the Burden of Parkinson's Disease project (CT-IDs: 6ef2e427b002, 6ef2e427b003, 6ef2e427b004), comprising three harmonised but independently conducted RCTs. All sites follow a shared core protocol, allowing for pooled data analysis while preserving site-specific perturbation adaptations. Findings from this trial will be reported both independently and as part of the combined dataset. In this trial, participants with PD will undergo 12 sessions of treadmill training, with or without virtual reality and perturbation-based adaptations. Assessments will be conducted at baseline, post-training, and follow-up. The intervention aims to enhance gait through improved sensorimotor integration and balance control. During the follow-up period, a smartphoneapp "Walking Tall" will be used to encourage continued exercises and long-term retention of training effects. Biomechanical analyses will focus on changes in foot placement control. Neurophysiological outcomes will be examined using EEG and EMG, targeting reductions in beta-band EEG power and enhanced EEG-EMG coherence as markers of improved gait stability. Recognising that laboratory-based improvements may not always translate to daily life, this study will also investigate gait self-efficacy as a potential moderator of transfer. Remote monitoring tools will capture real-world mobility outcomes over a week. Machine learning techniques will be employed to identify factors differentiating those who improve in both settings from those who do not. These insights will inform the development of personalised interventions capable of translating training effects into meaningful real-life outcomes.

Interventions
Exercise
SDTT adjusts the treadmill's speed in real time to match an individual's walking pace, creating a dynamic and adaptive training environment. This approach simulates real-world walking conditions, promoting neuromuscular coordination, balance, and functional mobility. By tailoring speed to the user's natural gait, SDTT supports the development of efficient and more natural walking patterns. It has shown promise across clinical populations, including those with neurological disorders, musculoskeletal conditions, or recovering from injury. Its flexibility allows for progressive challenge as walking ability improves, making SDTT a valuable tool for optimising gait and mobility outcomes.
Exercise
The SDTT+ program combines speed-dependent treadmill training with perturbations and VR-triggered adaptations. Reactive gait responses are elicited through controlled accelerations and decelerations of treadmill belts, simulating real-life balance challenges.
