Qualitative interviews with people with Parkinson's, supporters, and physiotherapists identify preferences for engaging, challenge-balanced dual-task (cognitive+motor) training, support for home-based adjuncts and technology, and hybrid assessment approaches to improve accessibility and adherence.

Although it offers no molecular or biomarker insights, the study provides actionable guidance for designing and implementing rehabilitation interventions and trial protocols that could enhance adherence, functional outcomes, and real-world translational uptake in Parkinson's therapeutics.

Dual-task training helps improve balance and cognitive function in people with Parkinson's disease, but existing clinician-led, clinic-based programmes lack standardization. This qualitative study aimed to inform new programme designs by exploring the experiences and needs of individuals with Parkinson's disease, their supporters, and physiotherapists. Semi-structured interviews were conducted with ten participants - six with mild-to-moderate Parkinson's disease, two supporters, and two physiotherapists. Interviews were recorded, transcribed, and independently analysed by two researchers using framework analysis. Three main themes emerged: what comprises "An Engaging Dual-task Training," emphasizing enjoyment, daily life integration, and the need for a balance between challenge and reward as well as the effectiveness of the task to be known; the impact of "Home-Based Dual-task Training," discussing the pros and cons of home-based training and technology use, and the opportunity to engage supporters as training buddies; the need for "Acceptable Assessment Options," exploring hybridization of the use of remote and clinic-based assessment methods. Participants valued traditional, clinic-based, clinician-supervised rehabilitation, while also supporting home-based adjunctive programmes for their potential to offer greater autonomy, flexibility, cognitive engagement, and inclusive integration into daily life.
