The overall objective of this study is to determine the feasibility of identifying transdiagnostic biomarkers of cognitive function mediated by neuromodulation of the dorsolateral prefrontal cortex that are translatable across disease groups in order to more accurately phenotype clusters of cognitive dysfunction. Completing behavioral paradigms with electrophysiology and TMS is a challenging frontier. This study focuses on the feasibility of such an endeavor for those with chronic pain or depression as well as healthy controls.

This study will develop a platform for stimulation setting optimization based on power spectral density (PSD) measures. Randomized, controlled trials have demonstrated that stimulation of the anterior nucleus of the thalamus (ANT) suppresses seizures. The central hypothesis tested here will be that PSD measured in the ANT will correlate with seizure frequency and stimulation settings that suppress broadband activity will result in lower seizure rates.

1.1 Purpose: This protocol will carry out Aim 2 (Experiments 1 and 3) of Udall Project 2, leveraging the novel (on-label, FDA-approved) local field potential measuring capability of the Medtronic Percept™ PC DBS system to study the effects of globus pallidus internus and globus pallidus externus (GPi, GPe) DBS on: the wash-out and wash-in dynamics of motor behavior and local field potentials (LFPs) and correlations between fluctuations in gait and LFPs during activities of daily living (recorded over 4 weeks).

This protocol will characterize the effects of deep brain stimulation (DBS) location (both adverse and beneficial) on motor signs in people with Parkinson’s disease (PD). This information can be used to inform future DBS protocols to tailor stimulation to the specific needs of a patient. If targeted dorsal GP stimulation is shown to significantly improve motor features that are typically resistant to dopamine replacement therapy, these experiments will likely have major impact on clinical practice by providing a potential strategy to these medically intractable symptoms.

This is a prospective study aimed at quantifying walking and balance in Parkinson's Disease patients in the clinical setting. To accomplish this, we will use a portable motion capture system that is widely used to study biomechanics in humans. Once quantified, we want to test the effects of deep brain stimulation (DBS) frequency in patients who already have DBS systems in place. Thus, our objectives are: 1. Develop an anonymized database of quantitative postural responses and gait of PD patients. 2. Develop software that can quantify the postural response and gait of PD participants using only standard video camera footage. 3. Test the effectiveness of bilateral high and low frequency STN-DBS on the postural responses and gait of PD patients using the portable motion capture system. 4. We will passively record thalamic LFPs from patients with Medtronic Percept DBS devices while the DBS is OFF, set to low frequency, and set to high frequency.

The purpose of the study is to test new biomarkers of amyotrophic lateral sclerosis (ALS) and primary lateral sclerosis (PLS) using MRI scans at 3 tesla (3T). Identifying biomarkers of a disease can lead to a better understanding of the disease as well as improved treatments.

This is a prospective, longitudinal cohort study involving data collection regarding performance of children with ALD and typically developing (TD)children on neurocognitive testing and collection of neuroimaging data. The first goal of this study is to understand more about how ALD affects a child’s brain and development in childhood as they take part in their normal medical care and monitoring. This is important to identifying the best ways to detect and treat manifestations of ALD such as cerebral ALD. The second goal is to learn about how ALD affects caregivers, so that clinicians can offer better support to families in the future.

We are trying to learn more about how the brain controls movement and how this affects function after stroke. We expect differences in the side of brain damage to result in distinct movements of each arm. We will collect information with standard clinical exams and movements during tasks completed on the Kinereach virtual reality system. We will compare results between people who have and have not had a stroke.

Freezing of gait is a common problem in people with Parkinson's disease. Episodes of freezing can be overcome when a sensory cue is provided. This study will further develop and study the efficacy of a wireless shoe insole that can monitor walking and provide a cue (acoustic or vibrotactile) when a freezing event is detected. The experiment is designed to further test the ability of the device and algorithm to reliably detect freezing and release the episode with an external cue. This study has the potential to develop a tool that can help reduce the incidence and severity of freezing events in people with Parkinson's disease.

This is a prospective study aimed at quantifying walking and balance in patients with parkinsonism in the clinical setting in addition to a living environment setting. To accomplish this, we will use a portable motion capture system that is widely used to study biomechanics in humans. Once quantified, we want to test the effects of deep brain stimulation (DBS) frequency in patients who already have DBS systems in place. Thus, our objectives are: 1. Demonstrate that parkinsonism patient-specific kinematics can be used to detect postural instability in the clinic using wearable IMUs. 2. Demonstrate that individualized, home-based postural response curves can detect postural instability and prospectively predict fall risk in patients with parkinsonism.

This study will be a multi-site, single-blinded, randomized controlled trial (RCT) that will screen older adults with mild cognitive impairment (MCI) using 4 steps (over the phone, in-person interview including informed consent, medical verification, exercise stress test/magnetic resonance imaging [MRI]). We will enroll 128 participants (target 96 completers, assuming 25% attrition rate at 6 months). After baseline assessment, participants will be enrolled and randomized within age (65-74 years of age or ≥75 years of age) and study site (Minnesota or Rochester) strata centrally at the University of Minnesota (UMN) to one of four groups: ACT, cycling only, SOP only, or control with equal allocation and using a randomization scheme generated by our UMN biostatistician (CI: Vock). Group allocations will be concealed to all investigators and data collectors. The interventions will last for 6 months with 12-month follow-up. Outcomes include: 1) cognition: composite measures of executive function and episodic memory, 2) AD signature cortical thickness: composite using structural magnetic resonance imaging (MRI), 3) functional connectivity in DMN: resting-state using functional MRI (fMRI), 4) aerobic fitness, and 5) clinical and pathological AD conversion. Cognition and aerobic fitness will be assessed at baseline, 3, 6, 12, and 18 months; AD conversion at 6, 12, and 18 months; and AD signature cortical thickness and DMN at baseline, 6, 12, and 18 months. PIs Yu and Lin have developed and tested strategies in their preliminary studies to successfully ensure the protection of human participants.

Almost 300,000 Americans with a spinal cord injury or disorder (SCI/D) suffer from reduced or complete loss of sensory and motor function, which can compromise functional independence and quality of life. The purpose of this study is to find better treatment options for improving sensation and movement after SCI/D.

This is a prospective study aimed at quantifying walking and balance in normal pressure hydrocephalus (NPH) patients in the clinical setting. To accomplish this, we will use a portable motion capture system that is widely used to study biomechanics in humans. Once quantified, we want to test the effects of ventriculoperitoneal shunt (VPS) on walking and balance among NPH patients. Thus, our objectives are: Aim 1: We will demonstrate the use of quantitative kinematic data on NPH patients pre-lumbar drain, post-lumbar drain and post-VPS in order to assess the predictive value of CSF removal on gait and balance. Aim 2: We will demonstrate the use of objective, neuropsychological data on NPH patients pre-lumbar drain, post-lumbar drain and post-VPS in order to assess the predictive value of CSF removal on cognition 3. We will demonstrate the use of objective, physical therapy data on NPH patients pre-lumbar drain, post-lumbar drain and post-VPS in order to assess the predictive value of CSF removal on therapeutic intervention in terms of walking and balance measures.
