The functional presentation of those with Parkinson's disease (PD) are complex, varying depending on cognition, physiological deficits, and support network. This study assesses the perceptions of fatigue across individuals with Parkinson's disease with different clinical presentations to guide clinicians in their selection of evidence-based interventions to facilitate greater functional outcomes. A mixed-methods design was used to collect data on the mental and physiological perceptions of fatigue, utilizing surveys and physiological measures such as heart rate. Participants were recruited from a community group targeting those with PD with inclusion criteria being a diagnosis of PD. Results for both heart rate and …

The ability of vertebrates to generate rhythm within their spinal neural networks is essential for walking, running, and other rhythmic behaviors. The central pattern generator (CPG) network responsible for these behaviors is well-characterized with experimental and theoretical studies, and it can be formulated as a nonlinear dynam- ical system. The underlying mechanism responsible for locomotor behavior can be expressed as the process of leaky integration with resetting states generating appropriate phases for changing body velocity. The low-dimensional input to the CPG model generates the bilateral pattern of swing and stance modulation for each limb and is consistent with the desired …

Vasomotor response is related to the capacity of the vessel to maintain vascular tone within a narrow range. Two main control mechanisms are involved: the autonomic control of the sympathetic neural drive (global control) and the endothelial smooth cells capacity to respond to mechanical stress by releasing vasoactive factors (peripheral control). The aim of this study was to evaluate the effects of respiratory muscle training (RMT) on vasomotor response, assessed by flow-mediated dilation (FMD) and heart rate variability, in young healthy females. The hypothesis was that RMT could enhance the balance between sympa- thetic and parasympathetic neural drive and reduce …
