Bilateral coordination of the lower extremities is an essential component of mobility. The corpus callosum bridges the two hemispheres of the brain and is integral for the coordination of such complex movements. The aim of this project was to assess structural integrity of the transcallosal sensorimotor fiber tracts and identify their associations...
Article
This perspective article provides a brief review of our understanding of how center of pressure (CoP) and center of mass (CoM) are traditionally utilized to measure quiet standing and how technological advancements are allowing for measurements to be derived outside the confines of a laboratory setting. Furthermore, this viewpoint provides descript...

People with multiple sclerosis (PwMS) exhibit impaired balance during different sensory environments and poor cerebellar peduncle microstructure. We aimed to examine associations between microstructures of the superior, middle and inferior cerebellar peduncles (CP) with visual, vestibular, and proprioceptive-based balance in PwMS. Twenty-seven PwMS...
Article
The corpus callosum is an important neural structure for controlling and coordinating bilateral movements of the upper limbs; however, there remains a substantial lack of knowledge regarding its association with lower limb control. We argue that transcallosal structure is an integral neural mechanism underlying control of the lower limbs and callos...
Article
Balance is a complex, sensorimotor task requiring an individual to maintain the center of gravity within the base of support. Quantifying balance in a reliable and valid manner is essential to evaluating disease progression, aging complications, and injuries in clinical and research settings. Typically, researchers use force plates to track motion...

Humans are exposed to extreme environmental stressors during spaceflight and return with alterations in brain structure and shifts in intracranial fluids. To date, no studies have evaluated the effects of spaceflight on perivascular spaces (PVSs) within the brain, which are believed to facilitate fluid drainage and brain homeostasis. Here, we exami...
Article
The application of transcutaneous electrical nerve stimulation (TENS) can improve motor performance in both healthy individuals and those who present with clinically detectable sensory impairments. The purpose of our study was to compare the influence of continuous and intermittent TENS applied to the anterior thigh and tibialis anterior muscles on...
Chapter
With recent successes in characterizing standing postural stability of people with neurological disorders, Time-to-Boundary (TTB) measures have potential to provide deeper insights into the impacts of Parkinson’s disease (PD) and dual tasking on postural control. The TTB captures the critical relationship between the body sway and base of support,...

Gait and balance deficits are significant concerns for people with multiple sclerosis (MS). Shoe cushioning can influence mobility and balance, but its effect on walking and balance remains unknown in MS. This study aimed to determine how shoe cushioning affects gait and balance in females with MS (FwMS). We hypothesized that extra cushioning would...
Article
Background: Quiet stance is impacted by Parkinson's disease and dual-tasking. Recently developed outcomes such as the time-to-boundary provide unique insight into balance by integrating center of pressure position with base of support. However, little is known about the effects of Parkinson's disease on time-to-boundary. In particular, the effects...
Article
Background : Clinical trials often report significant mobility differences between neurotypical and atypical groups, however, these analyses often do not determine which measures are capable of discriminating between groups. Additionally, indirect evidence supports the notion that some mobility impaired populations demonstrate similar mobility defi...
Article
Background Multiple sclerosis (MS) is an autoimmune-based chronic inflammatory disease characterized by the neurodegeneration of the central nervous system and produces postural dysfunction. Quiet or static standing is a complex task carried out through afferent sensory inputs and efferent postural corrective outputs. Currently the mechanisms under...
Article
Background: Gait performance often dictates an individual's ability to navigate the dynamic environments of everyday living. With each stride, the lower extremities move through phases of stance, swing, and double support. Coordinating these motions with high accuracy and consistency is imperative to constraining the center of mass within the base...
Article

Multiple sclerosis (MS) is a neurodegenerative disease that negatively affects the quality of electrical signaling throughout the central nervous system. Although impaired postural control is one of the most common symptoms in people with MS (PwMS), commonly reported metrics such as center of pressure (CoP) path length and velocity have not been gr...
Article
"Subjective evaluations of balance performance, like the modified Balance Error Scoring System (mBESS), are highly popular. Alternatively, quantitative measures may offer additional clarity in identifying balance dysfunction. A novel measure to define balance impairments is time to boundary (TTB), which represents the amount of time available to make...

Multiple sclerosis (MS) is a neurodegenerative disease that negatively affects the quality of communication throughout the central nervous system. Although impaired postural control is one of the most common symptoms in people with MS (PwMS), commonly reported metrics such as center of pressure (CoP) path length, velocity, and the root mean square...

The current results form this on-going study highlight the cortical influence for dynamic movements. Although cSP duration was not significantly different between groups or hemispheres, significant correlations were observed for turning metrics and cSP duration for the left hemisphere in PwMS, such that greater motor cortex inhibition was associate...

In this preliminary analysis of an ongoing data collection, results indicate that PwMS demonstrate decreased bilateral coordination during over-ground walking and poorer transcallosal white matter microstructural integrity of sensorimotor fiber tracts in comparison to an age and gender matched neurotypical cohort. PwMS walked with significantly poo...

People with MS (PwMS) often report significant asymmetries in strength and function between the legs which are associated with poorer postural sway and unstable walking. Currently there is limited understanding as to why these limb asymmetries exist and what regions within the central nervous system contribute to these mobility-limiting issues. It is also unknown how minimizing these lower limb asymmetries may affect, and potentially improve, balance ability in PwMS to facilitate movement during activities of daily living. We suggest that impairments in postural control are, at least in part, a result of reduced communication between the two sides of the brain in PwMS. This project makes use of a state-of-the-art non-invasive brain stimulation technique called transcranial magnetic stimulation along with diffusion-based MRIs to allow us to assess the brain’s structure and function related to communication between the right and left sides of the brain in PwMS.
