Coordination is defined as the harmonious function of parts for effective results. Coordination for the purposes of this dissertation will be applied to movement, specifically we will focus on the inter-limb coordination between the left- and right-legs during gait, and additionally we will look at the coordination (or coupling) of one's postural sway when intentionally tracking an external visual stimulus. This dissertation will use nonlinear analyses, specifically cross-recurrence quantification analysis (cRQA) and cross-sample entropy (cSE) to quantify the duration and synchrony of coordination in stroke survivors, healthy controls, and Parkinson's disease (PD) during different tasks. For the first study we investigated gait in a group of stroke survivors compared to age-matched controls at their preferred walking speed. Findings were able to distinguish distinct coordination patters between the groups. The second study quantified postural sway coupling in a group of controls and found that only the visual stimulus that resembled mathematical chaos caused learning. The third study examined the gait between stroke survivors and controls during a novel split-belt walking paradigm and found that the durations of coordination are typically less for the strokes survivors when compared to the controls, however, the directions follow the same trends as the controls. Suggesting stroke survivors still have the ability to adapt to novel walking paradigms. The fourth study examined the transitions when switching between two stimuli from study 2 and found that participants show context dependent coupling that is based on both the high- and low-frequency components of the stimuli. The final study examined the coordination in a group of controls, persons with PD, and persons with PD that also have freezing-of-gait. Although, no significant results were found in this manuscript, we do still believe people with PD will be able to provide more understanding to cRQA variables, and possibly provide insight into the freezing-of-gait we see as this disease progresses. This dissertation will complete a circle of coordination using nonlinear analyses to build a story about components we are currently missing when studying pathological populations. cRQA and cSE are able to define and quantify the unique aspects of coordination in gait and postural sway in healthy participants, controls, stroke survivors, and people with PD. Although there are plenty of avenues these analyses can still be explored, it is worth using them for analyses and possibly when creating paradigms to improve functional outcomes in pathological populations.
