Intervention
Outcome measures
Primary outcome
The main study parameter is the change in blood oxygenation level dependent (BOLD) signal in the bilateral anterior putamen during performance of a dual task containing a lower limb motor task and a cognitive task (functional MRI, pre-training vs. post-training assessment).
Secondary outcome
Secondary study parameters include the change in blood oxygenation level dependent (BOLD) signal in the bilateral caudate nucleus, the anterior cingulate cortex and the prefrontal cortex, during performance of a dual task containing a
lower limb motor task and a cognitive task (fMRI, pre-training vs. post-training assessment). Other secondary study parameters are prefrontal cortex activation (concentration of oxygenated and deoxygenated heamoglobin) during training and more general walking tasks (functional near infrared spectroscopy fNIRS; dual task walking, obstacle negotiation, walking at preferred speed). Also, magnetic resonance imaging will be used to obtain brain oxygenation levels during ankle movements and a cognitive task, resting state functional connectivity, grey matter volume and white matter integrity. Other secondary study
parameters are measures of gait, fall frequency, balance and mobility, community ambulation, cognitive functioning, health related quality of life, fear of falling and user satisfaction of the intervention. A pre-training vs. post training
assessment will be used for all secondary study parameters.
Background summary
In this trial, which is part of the Seventh Framework program V-TIME, neural correlates of plasticity of the V-TIME fall prevention intervention are investigated.
Study objective
Previous work showed that a shift in functional connectivity from the posterior to the anterior putamen can be seen in PD patients (Helmich et al. 2010). Thus, PD patients probably use their anterior putamen for both cognitive and simple motor tasks. In healthy persons, cognitive tasks mostly rely on the anterior putamen whereas simple motor tasks mostly rely on the posterior putamen. We hypothesize that a bottleneck in the anterior putamen causes reduced dual task performance in PD patients. Through the VR training, we expect to see compensation for this bottleneck in other brain regions. Thus, we hypothesise that treadmill training with VR will cause a partial shift of cognitive control from the anterior putamen towards other brain regions such as the anterior cingulated cortex, the nucleus caudatus and the prefrontal cortex.
Study design
Pre assessment (all outcome measures), intermediate assessments after 4 weeks (physical and mental functioning) and 6 weeks (physical and mental functioning and fNIRS) of training, post assessment (all outcome measures), 1 and 6 month follow up assessments (all outcome measures besides (f)MRI and fNIRS).
Intervention
At RUNMC (Nijmegen) 50 patients with PD will be randomized into one of these two groups:
1. Treadmill Training with Virtual Reality (TT+VR) for 12 weeks, three times per week;
2. Active control comparison of Treadmill Training alone (TT), 12 weeks, three times per week.
At TASMC (Tel Aviv) 40 patients with PD will be randomized into one of these two groups:
1. Treadmill Training with Virtual Reality (TT+VR) for 6 weeks, three times per week;
2. Active control comparison of Treadmill Training alone (TT), 6 weeks, three times per week.
