External vs Internal-triggered Augmented-reality Visual Cues to Treat Freezing of Gait

Parkinson DiseaseGait Disorders7 more

Postural instability, freezing-of-gait (FOG), and falls are among the greatest unmet needs in Parkinson disease (PD). FOG eventually affects more than half of people with PD, and is notoriously difficult to treat pharmacologically or via deep brain stimulation. Visual cues do improve gait freezing, but their efficacy and adoption is limited because they are not practical to use in all real-world situations. There is a need for a cueing technique that is on-demand and discreet - only perceptible to the patient. Fortunately, recent technological advances in augmented-reality (AR) enable such an approach. In this study, state-of-the-art AR glasses will be used to project digital cues that are only visible to the wearer, to determine if they can improve FOG. 36 individuals with PD and FOG will be recruited to perform an obstacle-course gait task under six cue conditions: no cue, conventional cue, constant-on AR, patient-hand-triggered AR (turns on when patient clicks button), patient-eye-triggered AR (turns on when looking down), and examiner-triggered AR. The AR cue is a set of images that appear on the floor at a patient's feet, mimicking floor lines. Gait performance will be captured on video and via body-worn wireless sensors that detect how each limb is moving. The investigators will determine whether individuals are cue-able with conventional visual cues, whether intermittent cues outperform constant-on cues, and whether cues triggered by an examiner outperform cues triggered by patients themselves.

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

Cerebral PalsyGait Disorders1 more

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.

Effects of Different Time Period of Standing Frame on Spasticity and Gait in Children With Spastic...

Spastic Cerebral PalsySpastic Gait

Cerebral palsy is a neurological disorder with abnormalities in muscle tone, movement disorders and motor incapability. It attributes to harm to the growing brain. Cerebral approach including brain and its palsy referred to weakness and problems while using the muscles. It is characterized by way of the incapability to normally control motor features, and it has. the capacity to have an impact on the general improvement of a child with the aid of affecting the child's capability to explore, talk, learn, and grow to be independent. Spastic CP is the most common type among children and debts for almost 77% among all instances. It is the major problem in CP child making movement difficult or even impossible.

Transcranial Direct Current Stimulation for Gait Recovery Following Stroke

StrokeGait1 more

Background: Stroke is a leading cause of adult disability. The ability to walk is considered as the most important physical activity in daily life and strongly associated with quality of life in patients with stroke sequela. Conventional transcranial Direct Current Stimulation (tDCS) can induce mixed effects to improve gait impairment after stroke. The problem of limited focal specificity of tDCS may lead to an ineffective stimulation and in turn may be reduced the potential application of tDCS in clinical routine. High-definition transcranial Direct Current Stimulation (HD-tDCS) allows inducing, in a non-invasive way, a transient excitatory neuromodulation of a given cerebral region and to obtain a very focused cortical effect. However, the clinical and neurophysiological effects of HD-tDCS remain largely unknown for enhancing gait recovery in patients with stroke. The investigators hypothesize that anodal HD-tDCS will enhance neural interactions between motor networks and, thereby, improve motor processing and gait relearning. The investigators propose to carry out a study on chronic stroke patients involving anodal HD-tDCS of the affected primary motor cortex combined with a physical therapy. This study has three main objectives: To compare the effects of two techniques of tDCS (anodal tDCS, anodal HD-tDCS) on clinical recovery in patients with chronic stroke. To assess the effects of these brain stimulation techniques on brain reorganization with electroencephalography (EEG). To assess the effects of these brain stimulation techniques on spatiotemporal gait parameters during walking with wearable motion sensors. Methods: 36 patients with ischemic or hemorrhagic stroke will be randomly assigned to one of 3 groups: anodal tDCS, anodal HD-tDCS, or sham stimulation. Each group will receive the corresponding stimulation therapy 3 times per week for 2 weeks, simultaneously with physical therapy. Before (T0) and immediately after the treatment period (T1) and again one month later (T2), standardized assessments of sensorimotor function areas are obtained together with spatio-temporal analysis. Brain reorganization is assessed with EEG before and immediately after the treatment period. These recordings will be used to compare and investigate the clinical and physiological effects of each treatment modality.

Deficit-specific Training in Spinal Disorders

Spinal Cord InjuriesMultiple Sclerosis4 more

Impairments of walking function after spinal cord lesion due to, for example, inflammation, ischemia or trauma are exceptionally diverse. Depending on the size, location and completeness of the spinal cord lesion, gait dysfunction is often multifactorial, arising from weakness of leg muscles, sensory impairments or spasticity. Locomotor function in humans with spinal cord damage can be improved through training. However, there are no evidence-based guidelines for the treatment of gait dysfunctions and no excepted standards of gait training in this large and heterogeneous group of patients. A lack of evidence-based guidance and standardisation prevents the development of optimal training programs for patients with spinal cord damage and rather broad and subjective clinical judgement is applied to determine patient care. Objective and quantitative techniques like three-dimensional (3D) full-body movement analysis capable of identifying the most relevant determinants of gait dysfunction at the single-patient-level are not yet implemented as diagnostic tool to guide physical therapy in this heterogeneous group of patients. The objective of this project is to further advance current clinical locomotor training strategies by applying a deficit-oriented gait training approach based on subject-specific, objective gait profiles gleaned from 3D gait analysis in chronic, mildly to moderately gait-impaired individuals with spinal cord damage due to inflammation (in multiple sclerosis, MS) or with traumatic or ischemic spinal cord injury (SCI; motor incomplete). Within a parallel-group clinical trial, gait impaired subjects will be characterized by detailed kinematic 3D gait analysis and either trained according to their individual deficits or treated with non-specific, standard walking therapy for six weeks. It is hypothesized that individually adapted, deficit-oriented training is superior in improving walking function than purely task-related, ambulatory training in patients with spinal cord damage. This project may pave the way to more efficient training approaches in subjects with spinal cord damage by transferring and implementing modern gait assessment techniques into clinical neurorehabilitation and to move towards individual, patient-tailored locomotor training programs.

The Effect of Conservative Treatment on Gait Biomechanics in Adolescent Idiopathic Scoliosis

Adolescent Idiopathic ScoliosisGait Disorder1 more

Adolescent idiopathic scoliosis (AIS) is a three-dimensional complex progressive structural deformity of the growing spine. Asymmetric changes in both the anatomical structure and strength of the muscles due to deformity affect weight distribution and joint moments in the trunk and lower extremities. As the spine transfers loads through the pelvis, asymmetry in the spinal alignment creates structural or functional changes involving other parts of the kinetic chain. The deviations caused by the deformity in all three planes and the responses to it affect the kinetics and kinematics of the trunk and extremities. A number of kinetic and kinematic changes such as decreased hip muscle strength, asymmetric lateral stepping, decreased hip and pelvic joint range of motion, especially in the frontal and transverse planes, and ground reaction force asymmetry has been demonstrated in patients with AIS. Understanding the postural changes and correction strategies that affect the displacement of the center of mass, ground reaction force and center of pressure during standing and walking in adolescents with idiopathic scoliosis is fundamental to understanding the nature of the disease, disease management and guiding rehabilitation both conservative treatment and after surgery. Based on this, it was aimed to objectively measure the biomechanical effects of the forces applied to the body in the brace to control deformity and prevent progression during the growth period, to determine postural control strategies, kinetic and kinematic changes in these patients with treatment by applying MOOR-S model brace and Schroth Three-Dimensional Scoliosis Exercise Treatment as a conservative treatment method on patients with AIS. In addition, it was also aimed to determine lower extremity inequality by measuring dynamic leg length with gait analysis in individuals with functional leg length discrepancy due to scoliosis.

A Multisite Exploration of Balance Perturbations With and Without Body Weight Support

StrokeStroke5 more

ZeroG is an FDA-listed robotic body weight support system (BWSS). Mounted on an overhead track, patients are fitted in a harness system tethered to said track, and are able to practice gait and balance activities without the risk of falling. This compensates for ineffective postural control permitting intensive therapy sessions earlier in recovery. The purpose of this study is to determine if inducing effective and safe balance perturbations during standing and walking in the BWSS more effectively improve postural control than the BWSS without perturbations. The target population are those patients in the post-acute phase of stroke admitted for inpatient rehabilitation of balance impairments. Site investigators and/or research staff will obtain names of potential subjects from internal reporting identifying inpatients who may qualify for the study based on the inclusion criteria. Trained site investigators will meet with potential subjects to explain the study, complete a screening interview for exclusion and inclusion criteria, answer any questions, obtain informed consent and HIPAA authorization, and schedule the study therapy sessions involving the protocol. Based on the randomization scheme provided by the lead site, consented subjects will be randomized to either the BWSS with perturbations (BWSS-P) or standard BWSS control without perturbations. Subjects will perform 2 to 6 sessions in their designated intervention using a structured protocol for each session. To compare differences between treatment groups, outcome measures will be collected at baseline before any BWSS sessions are performed and within 48 hours after completing the final treatment session.
