Experimental PBT Study in Fall-prone Subjects (PACE-R)

12. juni 2026 opdateret af: University Rehabilitation Institute, Republic of Slovenia

Experimental Perturbation-based-training Study in Patients After Stroke and Older Adults

The study will investigate safety, usability, feasibility and preliminary efficacy of perturbation-based training in participants post-stroke and older adults with mild balance deficits. Both group will receive three weks of training. The primary outcome measure will be derived from laboratory-induced falls.

Detaljeret beskrivelse

We will recruit two convenience samples to serve as self-controls, 20 post-stroke adults and 30 community-dwelling older adults. Participants post stroke will be recruited after discharge from their regular rehabilitation. Each subject will undergo individually customised perturbation-based training sessions with safety harnesses. The participants will be assessed at four time points: at baseline, after 3 weeks (at the beginning of training), at the end of 3-week training, and at 3-week follow-up. Safety, usability and efficacy of training will be evaluated using slip-, trip- and platform-movement-based perturbations induced by a Stewart platform and dual-belt treadmill, whereby the perturbation strength that can be reliably counteracted will be recorded, and using standardised clinical outcome measures.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Post-stroke patients
Each participant will undergo perturbation-based training and assessment according to an ABA (no intervention/intervention/no intervention) design with assessment at the beginning and end of each phase (four time-points).
Enhed: PBT
Each subject will undergo 9 perturbation-based training sessions with safety harnesses, and the device will deliver waist pulls during treadmill walking. Training sessions will be individually customised. Perturbation intensity will be progressively increased by a physiotherapist according to the subject's abilities. Training sessions will last approximately 30 minutes, 2-3 times per week.
