Filter by:The main hypothesis of the present study is that a safer knee joint is likely to encourage post stroke patients at an early stage to rely on their hemiparetic leg and transfer their weight onto it while walking. The main purpose of the present work is to assess the feasibility of FES-induced muscular control of the hemiplegic knee joint in order to improve stance phase support symmetry recovery in individuals with post stroke hemiplegia. Functional electrical stimulation (FES) is delivered to the quadriceps and hamstrings of the paretic limb based on the real-time estimation of the knee angle and support phase.
Foot and body postures of patients with DMD will be evaluated. Foot structure characteristics such as foot length, metatarsal width, calcaneal valgus angle will be calculated for the foot posture. Also, the Foot Posture Index (FPI-6) scale will be used. The body posture will be evaluated with the New York Posture Scale. Many gait characteristics such as step length, cadence, support surface of the patients will be determined with GaitRite instrumented walkway. Patients' balance assessment will be evaluated with Bertec Balance Advantage. The statistical analysis method will determine the relationship between foot and body posture and gait and balance.
Approximately 20% of stroke survivors have difficulties to dorsiflex the ankle and clear the ground during walking. This impairment, termed as "foot drop", is caused by an association of weak dorsiflexors and increased spasticity and stiffness of the plantar-flexors. As a consequence, walking performances are reduced and energy cost of walking is deteriorated. This may increase performance fatigability, as the locomotion will be realized at a higher percentage of the subjects' capacities. In order to overcome these issues, different treatments are proposed. One of the most conventional solutions are the use of ankle foot orthosis (AFO) and it is the most commonly prescribed device used to compensate for "foot drop". There is a very large choice of AFO on the market which can be proposed to patients with foot drop. The aim of this study is thus to assess the mechanical effects of using a manufactured carbon AFO in by comparison to a custom-made thermo-plastic AFO on walking capacity (distance and energy cost), fatigue and "foot drop" control throughout the gait phase in patients with hemiparetic stroke.
Background: One of the most disturbing motor symptoms in Parkinson's disease (PD) is gait disturbance. Clinicians often use various verbal instructions to correct abnormal gait patterns, and the most commonly used instruction is 'lift the foot up and make big steps.' Despite immediate performance improvement, people with PD are reluctant to walk outdoors with this exaggerated walking strategy because it makes them feel embarrassed, unbalanced, and fatigue easily. Since people with PD walk with flat foot, the investigators propose that an instruction emphasizing heel-strike at foot contact may be effective. When delivering verbal instructions, clinicians should also consider the attentional focus of the instruction. Evidence has shown that instructions with external focus of attention (EF) is more beneficial than internal focus of attention (IF) for motor performance and learning. However, most of the gait-related instructions for PD are IF. The investigators thus aim to design a novel EF instruction and determine whether people with PD can benefit more from EF than IF instruction. Objectives: (1) To investigate the effects of verbal instruction emphasizing heel-strike during gait training in people with PD. (2) To further determine whether an instruction with EF will induce greater training benefits than IF. Methods: Two experiments will be conducted in this study. In experiment 1, 60 individuals with PD will be randomized into the heel-strike (HS), big-step (BIG), and control (CON) groups. All participants will receive 12 sessions of gait training with the specific verbal instruction allocated for each group. The participants will be assessed before, immediately after, and 4 weeks after the interventions. The primary outcome will be gait performance, and the secondary outcomes will include measurements of cognitive and behavioral functions. Additionally, transcranial magnetic stimulation will be used to examine the changes of corticomotor excitability associated with the interventions. In the 2nd experiment, 46 individuals with PD will be randomized into the internal focus heel-strike (IF-HS) or external focus shoe-strike (EF-SS) group. Except for the verbal instruction provided to the participants, other intervention and testing procedures will be the same as experiment 1. Group × time repeated measures analysis of variance (ANOVA) will be used to compare the intervention effects among the groups, and a significance level will be set at α=0.05.
This study will enroll patients with Multiple Sclerosis and some difficulty with walking. The purpose of this study is to use Rhythmic Auditory Stimulation (RAS) a music therapy technique that provides rhythmic auditory cues (like a beat) to help improve a patient's movements, especially when walking. Participants will be asked to participate in a walking program (WP) with Rhythmic Auditory Stimulation (RAS), or a WP without RAS.
Gait enables individuals to move forward and is considered a natural skill. However, gait disturbances are very common in patients with burn injury. Major causes of functional impairment are pain and joint contractures. Recent studies focused on the application of robot-assisted gait training (RAGT). This study aimed to elucidate the efficacy and investigate the mechanism of motor recovery after RAGT on patients with lower extremity burn.
Gait analysis is a quick and powerful tool with a wide range of clinical applications in various fields. However, due to the expensive and highly specialized equipment required, gait studies are mostly limited to academic research centers and small sample sizes and no large-scale, randomized controlled trials have been performed. Several authors have proposed inexpensive accelerometer-based systems to remedy this situation. Through mathematic transformation they adequately measure step time and length. With these systems however only temporal spatial gait parameters can be recorded; kinetic gait parameters, such as ground reaction force, cannot be measured. As these kinetic parameters are important for clinical studies, especially in fracture and rehabilitation research different methods are needed. Its availability is mainly limited to research centers, conventional gait analysis is further hindered by its stationarity and that it only allows momentary views of the patient's gait in a confined research environment. Even smaller, wearable systems have to be attached to an external apparatus, or are limited by their battery capacity, data storage and other device specific factors. Furthermore, the use of these systems is at an early clinical stage and their full potential not yet developed. As most disease processes are continuous, tools with long-term, continuous measuring capabilities are needed. For this reason a new pressure-measuring insole with built in battery and data storage was developed in cooperation with the AO Foundation(AO Foundation, Davos, Switzerland). The system offers complete independence from any external measures for up to 4 weeks and monitors a patient step during this time. The purpose of this pilot study is to investigate which how TKA arthroplasty may impact gait during early and medium term rehabilitation phase. This will be done through the use of the OpenGo Sensor Insole (Moticon GmbH).
The aim of this study is to validate a smart insoles system in comparison to the gold-standard GaitRite for a pathologic gait. The device evaluate gait parameters in real time thanks to an embedded algorithm based on the processing of inertial measurement unit and 19 sensors signals. At D0 and D7, the patient is evaluated by both the GaitRite® system and the FeetMe Monitor® system simultaneously. Hemiparetic patients have two measurements 7 days apart. The patient repeats 5 trials at a comfortable speed on the GaitRite® mat while wearing the FeetMe® insoles. Each measurement is repeated by 4 different operators. A total of 20 trials are made by the patient.
Cerebral palsy (CP) is caused by a non‐progressive injury in the developing brain, which leads to problems in functional mobility, posture, neuro musculoskeletal functions and gait. Around 75% of children with CP are ambulatory however they have gait problems such as excessive knee flexion, stiff knee, crouch gait or equinus which affects the quality of gait. When constructing an effective treatment plan in children with CP, a comprehensive assessment should be performed. One of the most essential assessments is gait analysis. Gait analysis is used in the quantitative assessment of gait disturbances providing functional diagnosis, assessment for treatment, planning, and monitoring of progress. Gait analysis aims to determine the factors leading to gait disturbances. To reach this aim, a large amount of quantitative data concerning the gait characteristics of a patient is analyzed. The assessment of these data can be performed via standardized clinical videos, recorded with numerical video cameras used in conjunction with optical 3D systems. The purpose of this study was to confirm the test-retest reliability of a commercially available body-worn sensor— G-Walk® sensor system—for spatiotemporal gait parameters in children with CP.
The aim of the present study is to investigate reliability in dyslexic children and compare it with healthy peers.
