7 Clinical Trials for Various Conditions
This will be a pilot study to determine if a 6 week home training program can increase preferred step rate (cadence) in recreational runners. Increase in step rate has been correlated with decreased stress at lower limb joints in runners. This has the potential of decreasing overuse injuries in this population. Research participants will have their preferred cadence evaluated at the beginning of the study. The athletes will be randomly assigned to two groups. One group will continue to train without intervention and the other group will train at a cadence of 10% higher than their preferred step rate. At the end of 6 weeks the participants will have their preferred cadence reevaluated using the same method as pre-participation cadence was determined. The investigators hypothesis the preferred running cadence of recreational runners following the intervention will be 5-10% greater than prior to the intervention and the increased cadence will be maintained for 6 months following the intervention.
The purpose of this research study is to compare two different exercise treatments for walking problems in older adults. The investigators want to determine if participation in the exercise programs will improve walking and thinking abilities.
The purpose of this study is to investigate the implementation of a novel gait rehabilitation stimulus (G-EO System) that could advance current clinical practices. The goal is to establish the safety and feasibility of gait training using the G-EO System as well as investigating the impact on mobility, function, quality of life, and participatory outcomes. Research Design: We propose a single-blinded, randomized trial of electromechanically-assisted gait training using the G-EO System in patients with Parkinson's disease with gait disability. Specific Aim 1 will establish the safety and feasibility of gait training using the G-EO System. Specific Aim 2 will determine the efficacy of gait training using the G-EO System for improving mobility, function, and quality of life
The purpose of this study is to examine the reflex excitability of the rectus femoris in individuals with and without post-stroke Stiff-Knee gait. We use electrical stimulation of the peripheral nerve innervating the rectus femoris for a well-controlled reflex stimulus. We are investigating whether reflex excitability of the rectus femoris correlates with gait kinematics.
Phase II of this study includes a pragmatic clinical trial which will take place at Northwest Rehabilitation Associates (NWRA) in Salem, OR to verify the efficacy of the system in a physical therapy clinic.
The objective of this study is to determine the effectiveness of the NESS L300 (L300) in improving gait parameters, function, and quality of life among stroke subjects (greater than or equal to 3 months post stroke)with drop foot.
The aging population is at an exceptionally high risk of debilitating falls, contributing significantly to reduced independence and quality of life. It remains extremely challenging to screen for falls risk, and programs designed to mitigate falls risk have only modestly influenced the sizeable portion of the aging population experiencing one or more falls annually. Balance control in standing and walking depends on integrating reliable sensory feedback and on planning and executing appropriate motor responses. Walking balance control is especially dynamic, requiring active and coordinated adjustments in posture (i.e., trunk stabilization) and foot placement from step to step. Accordingly, using a custom, immersive virtual environment, the investigators have shown that sensory (i.e., optical flow) perturbations, especially when applied during walking, elicit strong and persistent motor responses to preserve balance. Exciting pilot data suggest that these motor responses are remarkably more prevalent in old age, presumably governed by an increased reliance on vision for balance control. Additional pilot data suggest that prolonged exposure to these perturbations may effectively condition successful balance control strategies. Founded on these recent discoveries, and leveraging the increase reliance on vision for balance control in old age, the investigators stand at the forefront of a potentially transformative new approach for more effectively identifying and mitigating age-related falls risk. The investigator's overarching hypothesis is that optical flow perturbations, particularly when applied during walking, can effectively identify balance deficits due to aging and falls history and can subsequently condition the neuromechanics of successful balance control via training.
