Active clinical trials for "Gait Disorders, Neurologic"

This pilot study investigates the feasibility of novel control strategies for actuated transfemoral prostheses. Several parameters from gait analysis (including motion-capture and ground reaction force measurements) are analyzed. The subjective perception of prosthetic functionality is captured with a questionnaire.

Total hip replacement surgery is a very successful operation with good long-term results. Hip resurfacing arthroplasty is offered as a treatment option for young and active patients with osteoarthritis of the hip. It has been proposed as a treatment option for younger patients because of claims that it preserves femoral bone stock and has better functional outcomes. The assessment of gait after hip replacement surgery may be able to determine functional differences between patients who have undergone total hip replacement / arthroplasty (THA) versus hip resurfacing.

For several years now, it has been demonstrated that the upper limb plays an important role in the function of an efficient and balanced gait pattern in healthy adults. After a stroke, the reduced muscle strength has a clear influence on the gait pattern, but also on the active movement possibilities of the upper limb. However, the role of the upper limb during gait is not sufficiently explored in the literature. The gold standard for motion analysis is a 3D analysis performed with infrared cameras capturing reflective markers during gait. Unfortunately, it is not possible for all people after a stroke to undergo this examination. On the one hand, patients must already have a certain degree of independence with regard to gait. On the other hand, not all centers have access to this expensive accommodation. There are some validated observation scales for people after stroke to describe the gait based on a 2D video image. This method is much more accessible and can be applied by any therapist. However, to date there has been little attention paid to the upper limb in these observation scales. Therefore, analogous to the observation scales for gait, an observation scale for the upper limb during gait was set up. The use of this scale can add value to the rehabilitation of people after a stroke. The treatment team will receive information about the patient's complete movement pattern. The arm will be more prominent when setting rehabilitation goals related to gait. This can lead to a positive effect on the gait pattern itself, but also to more attention being paid to the arm, which has a more difficult recovery than the leg after a stroke. The aim of the current study will be to determine the inter and intra tester reliability of this visual observation scale to investigate if the results of the visual observation scale correlate to a 3D assessment performed in a subgroup of participants

The aim of the study is to evaluate the short effects of a two rehabilitation session commonly performed in physical therapy, muscle strengthening of the lower limbs and effort reconditioning with cyclo ergometer, on gait characteristics (kinematics, kinetics and electromyographic) in patients with central nervous system lesion.

The freezing of gait (FOG) is one of the disabling symptoms in Parkinson's disease. The diagnosis and assessment of the FOG may be diffucult, but it is absolutely necessary. The aim of this study was to develop a Türkish version of the freezing of gait questionnaire (FOG-Q) and assess the validity and reliability of this Türkish version. The researchers firstly communicated with the developers of the FOG-Q. The permission for Turkish version was received by Giladi. Then, the FOG-Q will be adapted into Türkish using forward-backward translation by three native Türkish-speaking forward translators and one native English-speaking backward translator. The internal reliability of the FOG-Q Türkish version will be assessed using Cronbach's alpha, and item analyses will be conducted by examining the effect on Cronbach's alpha of excluding each of the six FOG-Q items individually. The test-retest reliability will be assessed using intraclass correlation coefficient (ICC). Convergent validity will be evaluated by means of Spearman rank correlation coefficient (rs). In this section will be determined the correlation between the FOG-Q scores and scores of the UPDRS motor section , Berg Balance Scale, Timed up and go test, Falls Efficacy Scale and Hoehn and Yahr stages.

In order to tailor interventions, objective assessments of physical function is needed. A limitation of several of today's clinical assessments is that they require too much time and/or space. The Timed Up and Go (TUG) is a commonly used clinical test of physical function in older populations. The TUG is particularly useful due to its short administration time and the little space that is required. The TUG is however of limited value when used in higher-functioning older adults due to ceiling effects. Instrumented versions of TUG (iTUG) computes several outcome measures in addition to the traditional outcome measure which is the total duration. The aim of this study is to evaluate the construct- and discriminative validity of outcomes derived from sensor signals recorded with a smartphone during a five times repeated iTUG (5iTUG).

This will be a pilot study to determine if a 6 week home training program can increase preferred step rate (cadence) in recreational runners. Increase in step rate has been correlated with decreased stress at lower limb joints in runners. This has the potential of decreasing overuse injuries in this population. Research participants will have their preferred cadence evaluated at the beginning of the study. The athletes will be randomly assigned to two groups. One group will continue to train without intervention and the other group will train at a cadence of 10% higher than their preferred step rate. At the end of 6 weeks the participants will have their preferred cadence reevaluated using the same method as pre-participation cadence was determined. The investigators hypothesis the preferred running cadence of recreational runners following the intervention will be 5-10% greater than prior to the intervention and the increased cadence will be maintained for 6 months following the intervention.

The aim is to investigate the biomechanical interaction between trunk and gait performance in both healthy and stroke subjects. People after stroke often have an impaired trunk function, resulting in balance and gait disorders. Pathological movement patterns after stroke can be compared with normative data as motion capture systems provide more sensitive data to explore the interaction between trunk performance and gait in contrast to the clinical measures used in literature.

This study will investigate if a lower limb robotic device can be used in a community setting to increase the amount of physical activity that individuals undertake following stroke and consequently improve biomechanical, physiological and health outcomes, in patients with stroke.

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).
