Background: Stroke can lead to gait abnormalities such as foot drop. Foot drop can result from decreased corticospinal tract input to the ankle dorsiflexors and/or from exaggerated stretch reflexes on the soleus due to reduced reciprocal inhibition from spinal reflex pathways. Transcranial direct current stimulation (tDCS) attempts to modulate corticospinal tract input and spinal reflex pathways by delivering electrical signals to parts of the brain. The degree of neuromodulation from tDCS can be measured through the Hoffman Reflex (H-reflex)—a tool used to estimate alpha motor neuron excitability which is increased in individuals post-stroke. Purpose: The primary purpose of this study …

[Purpose/Hypothesis] Stroke is a leading cause of disability that results in various neurological deficits. Stroke can cause impaired somatosensory input, which results in decreased balance and gait speed, ultimately increasing fall risks. Therapies to increase somatosensory input have shown promise for people with stroke as well as other neurological populations. However, few studies have systematically investigated varying somatosensory input via different footwear to improve walking in people post-stroke. The purpose of this study was to investigate the effects of altering somatosensory input via different types of footwear (i.e., barefoot, self-selected shoes, and memory foam shoes) on gait kinetics and ankle …

Background: Task-dependent neurophysiological adaptations in people with cerebral palsy have been examined using various techniques such as functional magnetic resonance imaging, peripheral nerve stimulation in order to assess H-reflexes, and transcranial magnetic stimulation. This activity-dependent plasticity is hypothesized to improve specific gross motor function in individuals with cerebral palsy. Although these adaptations have been examined extensively, most studies examined tasks utilizing the upper limbs. The aim of this review is to assess the neurophysiological adaptations of the central nervous system in individuals with cerebral palsy during lower limb functional tasks. Methods: A systematic review and meta-analysis will be conducted to …
