Dual-Task Balance and Gait Training Combined With Cognitive Training in Parkinson's Patients

The aim of the study is to examine the effects of a structured, cognitive dimension-specific cognitive training combined with dual-task balance and gait training on balance, gait, and cognition in individuals with Parkinson's disease.

Safety and Feasibility of TWIICE Rise - Phase 2

The aim of this study is to assess the safety and the feasibility of two versions of TWIICE Rise for exoskeleton-assisted ambulation in patients with a spinal cord injury. This study is done in two phases: The first phase evaluates the safety and feasibility of TWIICE Rise 0.0 with 5 patients over 6 sessions in clinic. The second phase is being conducted with TWIICE Rise 1.0. This version has potentially improved functionalities based on feedback from Phase 1. Safety and feasibility will be assessed with 10 patients over 10 sessions in different settings (clinic, home, and community environment).

Development and Efficacy of a Novel, Cost-Effective Gait Training Device Utilized at Home for Stroke Survivors

This pilot, parallel-group randomized controlled trial will evaluate the feasibility, safety, usability, and preliminary efficacy of the Rise\&Walk InHome (RWH), a novel robotic gait training device designed for home use after stroke. Twenty adults with lower-extremity motor impairment following a first-ever stroke (3 months to 5 years post-event) will be randomized 1:1 to either (1) RWH-assisted home walking plus usual care or (2) usual care alone for 12 weeks. Participants in the intervention group will receive an in-home RWH device, complete a structured device training program, and be instructed to perform 30-minute RWH walking sessions four times per week (48 sessions total). All participants will undergo standardized outcome assessments at baseline, weeks 4, 8, and 12, including the 6-Minute Walk Test (primary outcome), 10-Meter Walk Test, daily step count via wearable activity tracker, and health-related quality of life (SF-36). Additional feasibility and usability outcomes include device use and adherence, patient satisfaction and motivation, ease of use, perceived exertion, and adverse events. Findings will inform the feasibility of in-home deployment of the RWH device and provide preliminary effect-size estimates to guide the design of a larger efficacy trial.

Gamma Sensory Flicker for Parkinson's Disease Patients With Freezing of Gait

This study aims to answer the question: to assess the safety, and tolerability of gamma light in Parkinson's disease (PD) patients with freezing of gait (FOG). Parkinson's disease (PD) patients often experience a complex gait disorder known as Freezing of Gait (FOG). FOG is characterized by brief arrests of stepping when initiating gait, turning, and walking straight and patients describe it as their feet being "glued" to the floor. FOG in Parkinson's disease (PD) is a considerable public health burden worldwide. It is a poorly understood gait symptom that has potentially grave consequences as FOG is intermittent and unpredictable, a leading cause of falls with injury, and results in loss of independence. FOG is generally found to be associated with cognitive decline, particularly executive dysfunction which, in turn, has been associated with higher spinal fluid amyloid (Aβ42) levels in PD. There is data linking amyloid to FOG. A previous study showed that the gamma light helped reduce some amyloid. The research team is studying if gamma light exposure for 1 hour daily is well tolerated. Also, does it have any effect on freezing of gait severity?

Application of Device-based Training to Improve Postural Control in Older Adults With CCI

The goal of this clinical trial is to improve comprehensive rehabilitation programs for elderly patients with chronic cerebral ischemia by incorporating training methods with biofeedback for postural control training. The main objectives of the study are as follows: To evaluate the effectiveness of incorporating stabilometric training with biofeedback using the Huber system (LPG Systems, France) and treadmill-based biofeedback training using the C-Mill system (Physiomed Elektromedizin AG, Germany) into comprehensive rehabilitation programs, with respect to postural and cognitive functions in elderly patients with chronic cerebral ischemia. To conduct a comparative analysis of the effectiveness of training programs performed using the Huber (LPG Systems, France) and C-Mill (Physiomed Elektromedizin AG, Germany) biofeedback systems, based on outcomes related to gait pattern recovery, postural parameters, and cognitive performance. The investigators will compare training sessions using the Huber and C-Mill biofeedback systems with a control group (patients receiving conventional therapeutic exercise) in order to determine whether these devices are effective in improving postural control and reducing the risk of falls in patients with chronic cerebral ischemia. Participants are required to: Complete a course consisting of 8 procedures, performed once daily. Report any adverse events occurring during or after the procedures, should they arise.

Home-based Rehabilitation Monitoring System With Wearable Devices and Self-Report Application

The goal of this clinical trial is to evaluate whether monitoring and providing feedback on the performance of a home-based exercise program using an integrated wearable monitoring system improves physical and cognitive function, and activity level in participants with stroke. The integrated wearable monitoring system consists of an insole-type gait analyzer for objective gait assessment, a wrist-worn activity tracker for monitoring daily physical activity, and a self-report mobile application for delivering feedback and collecting participant-reported information. This study also aims to assess participant satisfaction with the integrated wearable monitoring system during a 6-week home-based gait rehabilitation program. The main questions this study aims to answer are: 1. What effect does monitoring and providing feedback using an integrated wearable monitoring system have on physical and cognitive function, and activity level during a home-based gait rehabilitation program? 2. How satisfied are participants with the use of the integrated wearable monitoring system? Researchers will compare an intervention group that receives the integrated wearable monitoring system with a control group that performs the same home-based exercise program without wearable monitoring and feedback. Participants in the intervention group will receive an insole-type gait analyzer, a wrist-worn activity tracker, and access to a mobile application, along with training in a prescribed home-based exercise program. During the 6-week intervention period, participants will wear the insole-type gait analyzer and the activity tracker while performing the home-based exercise program and will use the mobile application to receive feedback and self-report selected daily health-related information. After completion of the 6-week program, the investigators will conduct a satisfaction survey to evaluate participant experience with the integrated wearable monitoring system.

Ultrasonographic Assessment of Muscle Morphology, Function, and Clinical Findings in Spastic Cerebral Palsy

This study focuses on children with spastic cerebral palsy and aims to examine how muscle morphology and tissue characteristics, as assessed by ultrasound, may relate to functional motor abilities. It is designed as a prospective, cross-sectional, observational study. Planned ultrasound-based assessments include parameters such as muscle thickness, pennation angle, fascicle length, echo intensity, tissue stiffness (via shear wave elastography), and microvascular flow (via superb microvascular imaging). These measurements are intended to be compared with standard clinical evaluations, including the GMFCS, GMFM-66, MAS, MACS, and Tardieu Scale. The study seeks to contribute to a better understanding of the relationship between muscle architecture and functional outcomes, with the goal of generating insights that may inform individualized rehabilitation planning.

Enhancing Gait Using Alternating-Frequency DBS in Parkinson Disease

The purpose of this study is to assess how alternating-frequency Deep Brain Stimulation (DBS) works to improve postural instability and gait, while also treating other motor symptoms of Parkinson Disease (PD).

Effect of Electromagnetic Field Therapy on Balance and Gait in Paraparetic Patients

This study will investigate whether adding electromagnetic field therapy (EMT) to a standard physical therapy program is more effective than physical therapy alone for improving balance and walking ability in paraparetic patients. Thirty patients with paraparesis (weakness in the lower limbs) due to spinal cord lesions between levels T6 and T12 will be randomly assigned to one of two groups. Both groups will receive a 45-minute physical therapy session, three times per week for two months. The physical therapy program will include stretching, strengthening, balance, and gait training exercises. The key difference will be that one group (Group II) will also receive active low-frequency (0.5 Hz) electromagnetic therapy applied to their spine during their sessions, while the other group (Group I) will receive a placebo (inactive) EMT device. Patients will be assessed before and after the 2-month treatment period. The assessments will measure muscle spasticity (using the Modified Ashworth Scale), balance (using the Biodex Balance System), and detailed gait parameters like step length, stride length, and base of support (using a 3D motion analysis system

Reflex Excitability in Post-stroke Stiff-Knee Gait

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.

Effectiveness of a Powered Exoskeleton Combined With FES for Patients With Chronic SCI: a RCT

While there are a number of prospective studies evaluating powered exoskeletons in SCI patients, to date, not a single well-designed, randomized clinical trial has been published. However, there is evidence for beneficial effects of over-ground exoskeleton therapy on walking function post-intervention from a meta-analysis on non-randomized, uncontrolled studies. Functional electrical stimulation (FES), on the other hand, is a common and established method for the rehabilitation of persons with SCI and has been demonstrated to be beneficial in, e.g., improving muscle force, power output and endurance. Combining FES and overground robotic therapy within the same therapy session could potentially merge and potentiate the effects of each separate treatment, making it a very powerful and efficient therapy method. Up to date, however, comparative studies evaluating benefits of this combined approach (i.e., powered exoskeleton and FES) to robotic therapy without FES are missing.

Development of a Novel Strategy to Analyze the Effect on Gait Using Transcutaneous Spinal Current Stimulation in Incomplete Spinal Cord Injured Patients

To determine whether the combination of non-invasive spinal cord stimulation together with gait rehabilitation reduces spasticity and facilitates recovery of lower limb motor strength and gait function in patients with incomplete SCI, as well as studying the underlying physiopathological changes following incomplete SCI and its modulation by non-invasive stimulation techniques.

TRAIN-BW: Backward Walking Training in Multiple Sclerosis

Individuals with multiple sclerosis (MS) experience in impairments in mobility and cognition that increase the risk for accidental falls. More than 50% of individuals with MS experience injurious falls within a 6-month period. Current interventions to improve fall risk have focused on forward walking (FW) and balance training, resulting in small declines in the relative risk for falls with a large degree of variability. Interestingly, motor differences between MS and healthy controls are more pronounced in backward walking (BW), yet no studies have investigated BW training as an intervention to reduce fall risk in persons with MS. This study will investigate the feasibility, acceptability and impact of BW training compared to forward walking training on motor function and fall risk in persons with MS.

Investigating the Effects of Wearable Robotic Exoskeleton for Improving Mobility and Cognition in Persons With MS

The purpose of this research study is to evaluate the usefulness of a wearable robotic exoskeleton device (Ekso-GT), to improve learning and memory, and gait therapy in persons with walking disability due to Multiple Sclerosis. The study will evaluate the mobility, learning and memory, and walking abilities of individuals with multiple sclerosis who went through the traditional as compared to others who used the robotic exoskeleton as part of their therapy.

Percutaneous Ultrasound-guided Neuromodulation to Improve Gait Rehabilitation in Patients Who Have Suffered a Stroke.

The goal of this clinical trial is to learn if percutaneous ultrasound-guided neuromodulation (NMP-e) can improve gait rehabilitation in adults who have suffered a stroke. The main questions it aims to answer are: * Does NMP-e improve walking speed in stroke survivors? * Does NMP-e enhance muscle strength, functional mobility, reduce spasticity, improve balance, and increase health-related quality of life? Researchers will compare the addition of NMP-e to conventional physiotherapy versus conventional physiotherapy alone to see if the intervention provides additional benefits in gait rehabilitation and other functional outcomes. Participants will: * Continue their regular physiotherapy treatment consisting of passive and active-assisted mobilizations and strength exercises. * Receive NMP-e targeting the sciatic nerve at mid-thigh and the common peroneal nerve at the fibular head (experimental group only). * Undergo stimulation with an electrostimulator at 10 Hz for 10 seconds per trial, repeated 10 times, with intensity adjusted for comfort. * Be evaluated before the intervention, immediately after, and one week later using: * 10-Meter Walk Test for gait speed * Dynamometry for ankle plantarflexor and dorsiflexor strength * Time Up and Go test for functional mobility * Modified Modified Ashworth Scale for spasticity * Berg Balance Scale for balance * EuroQoL-5 Dimensions for health-related quality of life Participants must be adults aged 18-70, able to walk 10 meters without assistance, currently receiving physiotherapy, and able to provide informed consent. Key exclusions include pregnancy, bleeding disorders, needle allergies, systemic inflammatory disorders, or recent invasive physiotherapy. This randomized controlled trial will be conducted at ATECE, \*\*a Spanish association dedicated to the care and rehabilitation of individuals with acquired brain injury\*\*, where participants will be recruited and receive their interventions. The study aims to evaluate the potential of NMP-e as an adjunctive therapy for improving gait and related functional outcomes in subacute and chronic stroke patients.

Serious Game-based Intervention in Gait Rehabilitation for Children With Cerebral Palsy

Cerebral palsy (CP) is defined as a group of movement and posture disorders that cause activity limitation due to brain damage during fetal development or in the first year of life. Motor activities, and in particular walking, can be affected by many factors including sensory deficits, biomechanical and postural limitations, muscle weakness and spasticity. Theories of gait training guide rehabilitation management strategies. Among these, intensification, variability and specific training of walking parameters (speed, step length, cadence) have shown their effectiveness. Delivering sensory feedback during gait rehabilitation exercises is a complementary approach to improve motor learning during rehabilitation. On the other hand, motivation is a key factor in the success of rehabilitation. The addition of walking exercises performed through a serious game in augmented reality (AR) appears relevant for the rehabilitation of children with CP after surgery. The serious game ARRoW-CP is based on the latest advances in the literature in terms of gait rehabilitation protocol but also on the results of a clinical study conducted by our team, to identify the best feedback modalities to be delivered during the serious rehabilitation game.

Unsteady Gait in Older People May be a Common and Treatable Neurological Disease Associated With Increased Mortality

We live in an aging population and a third of the older population has a gait disorder that may cause institutionalization, and increased mortality. Sixteen percent of them have a slow, unsteady, neurological gait disorder, called Higher-Level Gait Disorder (HLGD). A known cause of HLGD is Idiopathic Normal Pressure Hydrocephalus (INPH), which is a treatable neurological disease. More than half of individuals with HLGD meet the diagnostic criteria for INPH as they have wide brain ventricles on MRI images of the brain, but far from all of these are in contact with the healthcare system. Possibly, HLGD without wide brain ventricles and where no other known explanation for the symptom is found could be a variant of or a precursor to INPH. Gait disorder is common among older people and can lead to falls and reduced quality of life. Complications after falls contribute to both increased mortality and increased costs in society. Therefore, it is important to have a solid knowledge of different types of gait disorders and how they can be treated. Our research will contribute with information about how HLGD affects the individual and how affected individuals can be investigated and helped. The disease mechanisms behind INPH and often behind HLGD are unknown. It is also unknown how often older individuals are affected by HLGD and how high the mortality is for those affected. It is likely that the incidence of HLGD is high and that it is linked to an increased mortality. It is also likely that the disease mechanism behind the symptom is the same as that of INPH and that HLGD can be detected with the help of brain imaging. In this epidemiological cohort study, we want to answer the following overarching questions: What is the incidence and mortality of HLGD and INPH? Can HLGD be predicted using biomarkers and what disease mechanism causes HLGD?

Efficacy of Cerebello-spinal Direct Current Stimulation (csDCS) on Functional Mobility in Chronic Stroke Patients

The aim of this clinical trial is to determine if cerebello-spinal direct current stimulation (csDCS) is effective in treating gait disorders in individuals with chronic stroke. Additionally, the trial seeks to evaluate the safety of this technique. The primary objectives include: Investigating whether cerebello-spinal direct current stimulation improves gait and functional mobility in participants with chronic stroke. Assessing any potential side effects associated with the method. Researchers will conduct a comparative analysis between cerebello-spinal direct current stimulation and a sham procedure (which mimics the stimulation without any actual effect) to assess its effectiveness in addressing gait disorders and enhancing mobility. Participants in the trial will: Undergo cerebello-spinal direct current stimulation combined with treadmill training or a sham procedure with treadmill training daily over a two-week period.

Brain Activity During Complex Walking in People With Atypical Parkinsonian Syndromes

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 atypical Parkinson's disease (APD) 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 ecologically valid state. The investigators aim therefore to explore brain function during complex walking in healthy and APD 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 older healthy adults and people with APD.

Support for Physical Activity in Everyday Life With Parkinson's Disease

This study aims to determine the effects of a motor-cognitive exercise intervention, delivered in the home environment using eHealth methods, among people with Parkinson's disease. The intervention will support and motivate motor training, combined with cognitive training, aimed at attentional and executive functions, among people at mild-moderate disease stages. The main hypothesis is that unsupervised motor-cognitive training in the home environment using eHealth will lead to improvements in gait performance, increased physical activity levels and improved perceived health.

Efficacy of Trans-spinal Magnetic Stimulation on Functional Mobility in Chronic Stroke Patients

The goal of this clinical trial is to learn if trans-spinal magnetic stimulation works to treat gait disorders in chronic stroke adults. It will also learn about the safety of trans-spinal magnetic stimulation. The main questions it aims to answer are: Does trans-spinal magnetic stimulation enhance chronic stroke participants gait and functional mobility? Does the technique cause any side effects? Researchers will compare trans-spinal magnetic stimulation to a sham (a look-alike stimulation with no real effect) to see if trans-spinal magnetic stimulation works to treat gait disorders and improve functional mobility. Participants will: Receive trans-spinal magnetic stimulation with treadmill training or a sham stimulation with treadmill training every day for 2 weeks.

Correlation of STN-DBS Induced Visuospatial Changes and Freezing of Gait

The purpose of this research is to determine how deep brain stimulation (DBS) for Parkinson's disease affects attention and visuospatial function. Additionally, this study will evaluate how deficits in visual attention are associated with freezing of gait (FOG) in Parkinson's disease. There is currently no reliable treatment for FOG and little is understood about the underlying reason this occurs. Some recent research has found that stimulating the right side of the brain seems to improve FOG. The right side of the brain is also paramount for visual attention, which is why investigators are conducting this study.

Locomotor Training With Testosterone to Promote Bone and Muscle Health After Spinal Cord Injury

This pilot study will determine the feasibility of implementing a combinatory rehabilitation strategy involving testosterone replacement therapy (TRT) with locomotor training (LT; walking on a treadmill with assistance and overground walking) in men with testosterone deficiency and walking dysfunction after incomplete or complete spinal cord injury. The investigators hypothesize that LT+TRT treatment will improve muscle size and bone mineral density in men with low T and ambulatory dysfunction after incomplete or complete SCI, along with muscle fundtion and walking recovery in men with T low and ambulatory dysfunction ater incomplete SCI.

Usability of the Smart Hallway System in Clinical Setting

The aim of the study is to examine suitability of data and processed reports acquired from the Smart Hallway system for clinical settings in terms of user acceptability and accuracy for use in clinical practice.
