About
Parkinson's disease (PD) is a neurodegenerative disease that affects about 1% of the elderly population and accounts for substantial disability and health care costs.
Disability is largely driven by mobility deficits caused by impaired gait. Effective treatments are available to restore lower limb function and improve gait, but response to treatment varies greatly from patient to patient and often shows only small effect sizes. Addressing this heterogeneity requires personalization, a concept referred to precision neurorehabilitation.
StimuLOOP.PD intends to foster structured and reproducible methods for precision neurorehabilitation of gait in PD. The investigator will conduct a proof-of-concept study to investigate a combination of two methods that are each tailored to the individual patient. Two innovative technologies are applied in concert to enhance recovery of lower limb function.
- Hyper-personalized feedback (HPF): For lower limb motor rehabilitation, the investigator will employ real-time continuous feedback for movement aspects that are specific to each participant's motor deficit. The feedback will be adapted and tailored to each participant. This results in a two-step personalization; in a first step, the investigator will choose what movement aspect is therapeutically targeted, and in a second step, the investigator will define how the feedback is presented to the participant.
- Targeted auditory stimulation during sleep (TASS):The investigator aim to reactivate rehabilitation- related memories through the presentation of auditory stimuli during sleep with the goal of promoting motor memory consolidation into stable motor commands.
The HPF intervention is expected to induce rapid adaptations, which however do not persist over multiple days. To counter this, the investigator will leverage memory reactivation during sleep to enhance the consolidation of the movement patterns that are learned during HPF.
The investigator expect that these interventions will lead to greater gains in functional walking ability. Beyond demonstrating a proof-of-concept for novel methods of precision neurorehabilitation, positive results of this project may have implications for neurorehabilitation treatment in general by providing first insights into the benefits and interplay of HPF and TASS.
