Active clinical trials for "Gait Disorders, Neurologic"

This observational study's main goal is to learn more about the neural mechanisms during movement in Parkinson's disease. Furthermore, it aims to inspire personalised treatment options. Participants will undergo a protocol that involves walking and gait-related motor tasks, such as seated stepping. During the protocol, brain activity will be recorded.

Cerebral Palsy (CP) is a non-progressive neurodevelopmental disorder that causes activity limitation resulting from movement and posture deficiencies as a result of a lesion in the immature brain. Children with CP usually have difficulties in mobility, transfer and social participation due to many motor and sensory disorders such as muscle weakness, decreased postural control, balance, spasticity.Hypertonus and abnormal motor patterns, lack of trunk control and postural disorders adversely affect the physical development of these children. Children with CP show various posture disorders due to proximal muscle strength losses leading to limitations and deficiencies in postural reactions. This leads to losses in reactive and antisipatory postural adjustments, and limits upper extremity functions such as walking, reaching, and eating. For this reason, children with CP have difficulties in maintaining balance while standing or sitting independently, walking, maintaining postural control in various environments such as walking, hills/uneven floors, performing activities of daily living (ADL) and social participation.

The purpose of this research study is to test the utility of an ankle robot, when used during treadmill walking, in people with ankle weakness and foot drop from a peripheral nervous system injury due to neuromuscular or orthopedic injury.

Prediction of walking recovery after stroke can inform patient-centered care and support discharge planning. The accuracy of current prediction models is limited, however, due to small study designs and narrow predictors assessed. The investigators propose a comprehensive evaluation of a novel combination of biomarkers to improve prediction of walking recovery and guide rehabilitation efforts after stroke. These include acute structural brain network disruption (utilizing MRI); blood biomarker levels (e.g., brain-derived neurotrophic factor and vascular endothelial growth factor); and clinical assessments of strength and mobility. The overall study objectives are to assess protocol feasibility and investigate relationships between select biomarkers and walking recovery to provide strong justification for a larger study on predictors of independent walking after stroke. The proposed objectives will be pursued through the following specific aims: 1) Assess feasibility of a larger study and develop methods for telehealth data collection; 2) Establish baseline levels of biomarkers and average change over time; and 3) Elucidate relationships between baseline levels of biomarkers and walking gains across time in persons after stroke. A longitudinal, observational study design will be utilized for this study. Thirty-five persons with acute (≤7 days) stroke will be recruited from the local medical center. Select inclusion criteria include presence of new lower limb weakness and assistance for walking; select exclusion criteria include cerebellar stroke or other neurological disorders such as Parkinson's Disease. Subjects will undergo clinical evaluation at week 1, 4, 9, 12, and 26 weeks post-stroke. MRI scans will occur within 12 days post-stroke and at 12 weeks post-stroke, and blood draws within 1 week, 1 to 2 weeks and at 12 weeks post-stroke. To assess feasibility the investigators will examine study processes, recruitment, resources, study management, and scientific assessment. To examine the role of acute clinical, neuroimaging, and physiological measures in predicting walking recovery, the investigators will examine relationships between these measures and walking outcome at 12-weeks post-stroke. The proposed research is expected to provide strong scientific support for future clinical trials designed to target therapies based on predicted functional potential. Such knowledge has the potential of enhancing mobility gains and patient independence following stroke.

It is the clinical experience of the authors that some children with cerebral palsy who walk in crouch gait show sufficient knee extension during the clinical gait analysis, but walk in considerable knee flexion when they leave the gait laboratory. Possible differences between walking in a gait lab and walking in daily life may be caused by the effect of observational awareness in the lab (also known as the Hawthorne effect), and the lack of dual-tasks (DT) during the analysis (which are common during daily life walking). Since so far there is no technique to reliably measure gait kinematics in children with CP outside of the laboratory, the researchers aim to objectify the influence of both the Hawthorne effect and dual-tasks by introducing different conditions during a standard clinical 3D gait analysis.

This study aims to provide a novel scientific contribution through addressing critical knowledge gaps, examining the effects of attentional focus instructions on real-time (state) conscious movement processing propensity, gait parameters, and muscle efficiency in older adults in Hong Kong at risk of falling while walking in a challenging environment. The study results could update our scientific understanding of the mechanisms of conscious movement processing and the interventional effects of attentional focus instructions in older adults. It could ultimately enhance the methodology used for developing the most appropriate psychomotor gait re-education intervention in rehabilitation and provide clear guidelines on the exact attentional focus training that older adults require. Further, it could mitigate the effect of conscious movement processing and risk of falling in older adults.

It has been reported that gait coordination changes in patients with chronic low back pain, walking slower, taking shorter steps and having asymmetrical stride lengths compared to their healthy peers. In addition to many factor cause gait dysfunction, sacroiliac joint dysfunction might be one of reason of these problems. A study examining the effects of sacroiliac joint dysfunction on gait and disability in individuals with chronic low back pain has not been found in the literature. Therefore, the aim of this study is to evaluate the gait parameters and disability of individuals with chronic low back pain and to reveal their relationship with sacroiliac joint dysfunction.

Every-day life means being part of a complex environment and performing complex tasks that usually involve a combination of motor and cognitive skills. However, the process of aging or the sequelae of neurological diseases such as Multiple Sclerosis (MS) compromises motor-cognitive interaction necessary for an independent lifestyle. While motor-cognitive performance has been identified as an important goal for sustained health across different clinical populations, little is known about underlying brain function leading to these difficulties and how to best target these motor-cognitive difficulties in the context of rehabilitation and exercise interventions. The challenge of improving treatments of motor-cognitive difficulties (such as dual-tasking and navigation) is daunting, and an important step is arriving at a method that accurately portrays these impairments in an ecological valid state. The investigators aim therefore to explore brain function during complex walking in MS (in comparison with people with Parkinson's disease and healthy controls) by investigating the effects of neurological disease on motor-cognitive performance and its neural correlates during three conditions of complex walking (dual-task walking, navigation and a combination of both) using non-invasive measures of brain activity (functional near infrared spectrometry, fNIRS) and advanced gait analysis in real time in people with MS (in comparison with people with Parkinson's disease and healthy adults).

The challenge of improving treatments of motor-cognitive difficulties (such as dual-tasking and navigation) is daunting, and an important step is arriving at a method that accurately portrays these impairments in an ecological valid state. The investigators aim therefore to explore brain function during complex walking in healthy and PD by investigating the effects of age and neurological disease on motor-cognitive performance and its neural correlates during three conditions of complex walking (dual-task walking, navigation and a combination of both) using non-invasive measures of brain activity (functional near infrared spectrometry, fNIRS) and advanced gait analysis in real time in young, older healthy adults and people with PD.

The goal of this clinical trial is to compare the gait of patients with hemiplegia, with or without the use of insole splint. The main questions it aims to answer are: Does the insole splint improve the gait of these patients? Does any difference exist in the use of muscles? Participants will have to walk in the gait analysis' aisle with and without the insole splint, using wireless EMG device.
