41 Clinical Trials for Various Conditions
Gait changes in Parkinson's disease are complex, variable, and difficult to detect during short clinic assessments. The aim of this study is to collect gait measurements in Parkinson's patients through sensors in a novel shoe device, NUSHU by Magnes AG. The shoe additionally provides vibrational feedback that can potentially help gait difficulties experienced by Parkinson's patients.
The purpose of this study is to evaluate the clinical performance of the investigational REEV SENSE gait tracker to measure gait features in subjects with post-stroke gait impairment. REEV SENSE is intended to be used by trained healthcare professionals as a simple procedure adapted to clinical routine. The reference method for performance comparison will be motion capture.
Previous motion analysis studies have demonstrated excellent ability to distinguish subtle differences in gait between normal subjects and those suffering from arthritis. With proper techniques and analysis differences between osteoarthritis patient groups can be distinguished. Previous research has indicated that subjects who received a single-radius design total knee replacement have superior gait performance that those who received a multi-radius design total knee replacement. The DJO Global Empowr PS Knee System is a single-radius lateral pivot design. This design should achieve reproducible more natural knee function and improved patient outcomes and satisfaction. A motion analysis laboratory will be used to collect gait data from patients who are going to receive a Empowr PS knee device and also from age-matched control subjects. These data will be compared with data previously collected from patients who received Stryker Triathlon devices, Biomet Vanguard devices and age-matched healthy control subjects.

If interested, subjects are informed by a study investigator of the study goals, procedures, risks and any benefits. A study investigator is responsible for obtaining informed consent. Data from normal subjects are used to establish a normative database. Data from other subjects contributes to the relevant databases of different disorders.
Hypotheses: • A wearable sensor system can be used to accurately monitor three common gait parameters: gait speed, stride length, and torso motion. Objectives: This study will examine the feasibility of using wearable sensors to monitor common gait parameters: gait speed, stride length and torso motion. A wearable sensor system of 8 commercially available inertial measurement units (IMU) will be composed. These sensors will work in unison to monitor the gait parameters. Technical Objectives * Gather information on commercially available IMUs * Use computer software to monitor and record data from IMUs * Develop an algorithm that can monitor volunteer gait speed, stride length and torso motion * Develop a graphical algorithm that compares healthy patient data to potential mild traumatic brain injury (mTBI ) candidates * Determine if there is a potential for mTBI determination using the wearable sensors * Accurately validate the wearable sensor system to the gait parameters measured using a Vicon motion analysis system
The objective of this research is to investigate the feasibility of delivering gait treatment using the Moterum iStride Solution™ to individuals with hemiparetic gait impairments using a telemedicine modality, the Moterum Digital Platform.
Our primary aim with this trial is to measure participant blinding following two simulated/sham or genuine/real high velocity, low amplitude (HVLA) manual chiropractic adjustments to assess if participants are able to identify their un-disclosed treatment group. Our secondary aims with this trial are to utilize electrocardiography (ECG), impedance cardiography (ICG), and gait analysis before either treatment session and after both treatment sessions to assess if there are any changes with the participants' measurements before and after a sham or genuine HVLA chiropractic treatment.
The purpose of this research is (1) to identify disease specific walking-related digital biomarkers of disease severity, and (2) monitor longitudinal changes in natural environments, for extended periods of time, in DMD and SMA.
The proposed study is designed to evaluate how foot loading changes during initial accommodation to a carbon fiber custom dynamic orthosis (CDO), after targeted training with or without visual feedback of foot loading, and after take-home use of the CDO. This study will quantify initial offloading associated with CDO use and determine if visual feedback of foot loading and additional take-home use of the CDO can further reduce forces, as orthotists work to provide CDOs to patients.
The investigators aim of the study is to assess the effects of early mobilization after surgically treated unicondylar tibia plateau fractures (6 weeks without weight bearing) on gait, patient satisfaction, return to work/sports and complication rate. The data will be compared to a 10-12 week non-weight bearing group (standard of care). It is assumed that earlier mobilization does not lead to an increase in the complications - in particular osteosynthesis failure and infections -, but leads to improved patient satisfaction, reduced return to work/sports times, and has a positive impact on the overall outcome
Stroke is among the leading causes of long-term disability worldwide. Post-stroke neuromotor impairments are heterogeneous, yet often result in reduced walking ability characterized by slow, asymmetric, and unstable gait patterns. Rhythmic Auditory Stimulation (RAS) is an emerging rehabilitation approach that leverages auditory-motor synchronization to retrain neuromotor control of walking. Indeed, walking with RAS can enhance walking rhythmicity, gait quality, and speed. RAS is a potentially valuable tool for walking rehabilitation after stroke; however, despite extensive research evidence on the overall benefits of RAS in people with chronic stroke, the notable variability in the walking characteristics of individual patients is likely to influence the effectiveness of RAS intervention, and thus requires study. Furthermore, beyond stroke-related factors, age-related changes may also affect how well individuals post-stroke respond to RAS. This study aims to recruit 24 individuals post-stroke and 20 older adults to evaluate the effects of stroke- and age-related neuromotor impairment on RAS intervention. Each study participant will complete two six-minute walk tests: one without RAS (baseline) and the other with RAS delivered using a metronome. The investigators hypothesize that post-stroke individuals will, on average, exhibit a positive response to RAS intervention (i.e., walk farther and with greater gait automaticity (i.e., reduced stride time variability), with the degree of response predicted by specific baseline characteristics. Furthermore, the investigators anticipate that these walking enhancements will be accompanied by improvements in gait biomechanics and a reduction in the metabolic cost of walking. The investigators hypothesize that older adults will exhibit similar, but attenuated, effects of RAS.
Parkinson disease (PD) is the second most common neurodegenerative disease affecting approximately 10 million people worldwide. It is a complex movement disorder that results in reduced walking ability. Prior studies have identified declines in walking as a marker of ensuing disability. Rhythmic auditory stimulation (RAS) is a rehabilitation approach that employs the coupling of auditory cues with movement. Walking with RAS has been shown to benefit walking rhythmicity, quality, and speed. These walking benefits make RAS advantageous in promoting regular moderate-intensity walking activity -- an important health objective in the management of PD. However, there is limited research investigating the effects of RAS on walking quality and how improvements in walking speed are achieved. This study will enroll 30 individuals with mild to moderate PD where each participant will be asked to complete two six-minute walk tests, one standard test (baseline) and the other using an optimized metronome-based auditory cueing RAS intervention. The investigators hypothesize that individuals with PD will either walk farther or with more automaticity (i.e., reduced stride time variability) in the RAS condition compared to the baseline condition. Moreover, these walking improvements will be accompanied by improvements in gait mechanics and metabolic cost of walking.
The goal of this study is to validate an MS Gait Remote Capture and Analysis (MS-GRCA) system based on wearable shoe-based motion sensors for home-based and repeatable gait assessments.
Carbon fiber custom dynamic orthoses (CDOs) consist of a proximal cuff that wraps around the leg just below the knee, a posterior carbon fiber strut that stores and returns energy during gait, and a carbon fiber foot plate that supports the foot and allows bending of the posterior strut. The proximal cuff is a primary interface between the patient and the CDO and may influence comfort, preference, limb mechanics and loading, and effective stiffness of the CDO. The important role of the proximal cuff has not been examined. The purpose of this study is to determine the effects of CDO proximal cuff design on patient reported outcomes, limb mechanics and loading, and CDO mechanical characteristics.
Robotic lower limb exoskeletons aim to improve or augment limb functions. Automatic modulation of robotic assistance is very important because it can increase the assistive outcomes and guarantee safety when using exoskeletons. However, this automatic assistance adjustment is challenging due to person-to-person and day-to-day variations, as well as the time-varying complex human-machine-interaction forces. In recent years, human-in-the-loop optimization methods have been investigated to reduce participants' metabolic costs by providing personalized assistance from robotic exoskeletons. However, metabolic cost measure is noisy and the experimental protocol is usually relatively long. In addition, the influence of exoskeleton control on this human state in terms of energetic cost is unclear and indirect. More importantly, the optimization by reducing metabolic cost is found to affect human gait patterns and cause undesired outcomes. In this study, new evaluation measures other than metabolic cost will be investigated to optimize the assistance from a powered hip exoskeleton based on a reinforcement learning method. It is hypothesized that the new reinforcement learning-based optimal control approach will produce personalized torque assistance, reduce human volitional effort, and improve balance and other performance during walking tasks. Both participants without and with neurological disorders will be included in this study.
The proposed study evaluates the effect of medial and lateral wedges and carbon fiber custom dynamic orthoses (CDOs) on lower limb forces and motion during walking. Previous work has used foam wedges of different stiffness and height placed under the heel to alter CDO alignment and alter lower limb mechanics. Medial or lateral wedges have been used by individuals with unilateral knee osteoarthritis in effort to reduce knee loading. In this study, medial and lateral wedges will be placed in participants shoes, with the tall side of the wedge placed on the medial or lateral aspect of the shoes, and participants will walk at controlled and self-selected speeds and complete physical performance measures. Participants will also walk without a CDO. The proposed study will provide evidence that can be used by physicians when treating knee osteoarthritis.
The proposed study evaluates the effect of carbon fiber brace design on forces across the ankle. Research suggests that ankle arthritis develops following ankle fracture due, in part, to elevated forces on the cartilage. It is expected that carbon fiber braces can reduce forces in the ankle joint thereby reducing the risk of developing arthritis following injury. In this study, carbon fiber braces will be tested to determine how they influence the forces acting on the ankle cartilage. The proposed study will provide evidence that can be used by clinicians and researchers to design carbon fiber braces to effectively reduce forces on ankle cartilage.
The proposed study evaluates the effects of a hands free crutch (iWalkFree, Inc.) on walking balance and stability compared to standard crutches. It is expected that the hands free crutch will provide better stability during walking on a level surface and better reported balance confidence compared to standard crutches. In this study, walking stability will be assessed using motion capture data from an infrared camera system with 12 mounted cameras surrounding a level walkway. Balance will be assessed through a self-reported activity-specific balance confidence (ABC) questionnaire. An improved understanding of the effects of the hands free crutch on gait may benefit the future prescription of ambulatory assistive devices. The proposed study may provide insight that can be used by physical therapists and other providers to select the ambulatory assistive device that best meets their patients' needs.
The primary purpose of this research study is to determine if the stiffness of a commercially available ankle foot orthosis (Malleo-Lok, Bio-Mechanical Composites, Des Moines IA) impacts gait biomechanics and overall joint level stiffness. Previously published research suggests that AFO stiffness can affect gait biomechanics and patient preference. However, previous studies have focused on traditional posterior strut devices with the strut aligned in the frontal plane to allow sagittal plane deflection. The Malleo-Lok is a novel, low-profile carbon fiber device with two laterally positioned struts aligned in the sagittal plane. The proposed study will provide insight that can be used by certified prosthetists orthotists (CPOs), physical therapists, and physicians to select the device that bests meets their patients' needs.
The proposed study evaluates the effect of carbon fiber brace design on forces across the ankle joint. It is expected that carbon fiber braces can be designed to reduce forces in the ankle. In this study, brace geometry will be varied to determine how these changes influence the forces experienced by ankle cartilage. The purpose of this study is to refine a pre-existing musculoskeletal model and finalize the procedures for inputting multiple data sources into the model to evaluate ankle articular contact stresses.
The proposed study evaluates the effect of ankle foot orthosis (AFO) heel height and stiffness on the forces and motion of the lower limb during over-ground walking in individuals who use an AFO for daily walking. Previous studies suggest that heel height and stiffness effect limb loading, but these data and the analysis techniques applied are limited. In this study, heel cushions with different height and stiffness's (4 conditions) will be placed in participants shoes and they will walk at controlled and self-selected speeds. Participants will also walk with their AFO as configured prior to enrollment, and with no AFO if possible. The proposed study will provide evidence that can be used by clinicians and researchers to align braces that most effectively improve function during every-day walking.
The proposed study evaluates the effect of carbon fiber brace design on forces across the ankle joint. Research suggests that ankle arthritis develops after ankle fracture, in part, due to elevated forces on the cartilage. It is expected that carbon fiber braces can be designed to reduce forces in the ankle joint and thereby reduce the risk of developing arthritis following traumatic injury. In this study, brace geometry will be varied to determine how these changes influence the forces experienced by ankle cartilage. The proposed study will provide evidence that can be used by clinicians and researchers to design braces that most effectively reduce forces on ankle cartilage.
