Abstract

Changing direction by turning during walking is particularly hard for patients with Parkinson Disease (PD), and can reveal coordination deficits that maybe hidden during regular walking. The aim of this study was to investigate how inter-limb coordination between arms and legs are affected by PD during walking with turning. Participants with idiopathic PD with freezing of gait (FOG) and without freezing of gait (nonFOG) and healthy older adults performed overground walking trials. Participants were instructed to walk at a comfortable pace back and forth continuously between two lines wearing wireless inertial sensor on the wrists and ankles. Data analysis was done separately for the whole walking trial that included both straights and turns and only the straight walking portion. To quantify the duration of coordination between the limbs, cross recurrence quantification analysis (cRQA) was used, and to measure the synchrony between the limbs, cross sample entropy (cSE) was used. The results showed that a) duration of coordination between the arms for the straights was shorter for FOG and nonFOG compared to controls; b) these differences disappeared for the whole; c) asynchrony between arms was increased for straights in both PD groups though only control and nonFOG was different in whole. In summary, the control of inter-limb coordination during walking may be restricted by the complexity the task if it includes turning. Turning can reveal unique coordination patterns among people with PD. Future studies should investigate the balance control during turning which can be targeted with potential rehabilitation paradigms.
