The Effect of Compensation Strategies on Gait Impairment in Parkinson's Disease

Gait disturbances are disabling and common in Parkinson's disease (PD). Patients use many different, and typically self-developed, strategies to compensate for their walking abnormalities. There is a wide variety of compensatory strategies, of which external and internal cueing are the most commonly known. External cueing refers to externally produced predictive stimuli such as a metronome, whereas internal cueing refers to a movement reference generated internally, such as counting while walking. The efficacy of external and internal cueing varies dramatically across patients, and some patients can even be identified as 'non-responders' to a particular cue. Consequently, a one-size-fits-all approach simply does not suffice, which increases the need for better understanding of the key mechanisms behind these compensation strategies. Furthermore, it is still unknown how the efficacy of compensation strategies changes longitudinally. The goal of the UNITE-PD project is to address these questions. The investigators aim to investigate whether the efficacy of internal and external cueing changes over time, and whether it is differentially affected in responders and non-responders. In order to work towards a more personalized treatment for patients with PD, the investigators also aim to identify potential patient characteristics that can mediate the actual use of compensation strategies in daily life. The multicenter UNITE-PD project is divided in a joint package and individual si…
