Filter by:Muscle behaviour of calf muscles can be studied during dynamic conditions using dynamic ultrasound. In particular, the medial gastrocnemius is suitable for measurements with dynamic ultrasound due to its superficial location. With this measurement technique, the muscle behavior during walking can be observed gaining insight into the mechanism of action of this muscle during a functional task. This technique has already been used in other populations (such as children with cerebral palsy) but not yet in individuals after a stroke. Therefore, the aim of this study is to assess the muscle behavior of the medial gastrocnemius during walking in persons after stroke. There are 3 concrete objectives of the current study: 1. is the technique feasible to perform in persons after stroke? 2. does the use of the dynamic echoprobe change gait patterns? 3. can differences between persons after stroke and healthy controls be detected? This data can be used as pilot data for project applications in the future that will allow to design larger studies. Therefore, 10 stroke patients and 10 age- and gender-matched healthy controls will walk on a treadmill for 3x2 minutes after a familiarisation period of 6 minutes. During 1 x 2 minutes, subjects will walk without using the dynamic ultrasound. This recording aims to measure the normal gait pattern of the subjects. During the other 2x2 minutes, subjects will walk using the dynamic ultrasound at 2 different locations on the calf. Once with the ultrasound probe on the centre of the muscle belly to visualise muscle fibre bundles and once on the muscle tendon transition, from which muscle belly and tendon length can be derived. The use of ultrasound or not will be randomized to exclude the effect of fatigue on the outcome measures.
The Ceriter Stride One (CSO) is a "smart sole" with pressure sensors. The sole allows data on the displacement of the body's centre of gravity (COG), as well as spatiotemporal parameters, to be obtained via pressure recordings. Logarithms, released on the data captured by the sole, make it possible to recognise propulsion (forward movement of the CG), accompanied by a reduction in step length (festination) or feet remaining standing (freezing of gait). When the system registers incipient propulsion, an audio signal ("stop") is generated via an audio device and app on the mobile phone. The CSO aims to make the pwP stop before balance disturbance can occur, preventing further propulsion and falls. The aim of the study is to explore the short-term effects of the CSO in terms of reducing (preventing) freezing of gait and fall risk in a pilot group of pwP whose functionality is limited (Hoehn and Yahr 4). Short-term impact on gait (episodes of freezing of gait, mean step length, mean gait speed) will be evaluated and user satisfaction surveyed.
Correcting of the lack of regularity in steps is a key component of gait rehabilitation in Parkinson's disease. The proposal is to introduce adaptive spatial auditory cueing (ASAC) based on verbal instruction "lengthen the step" automatically delivered when the stride length decreased below a predetermined threshold. The present study compared the effect of usual rhythmic auditory cueing versus ASAC used during a walking training in Parkinson's disease.
İntroduction The upper limb can be involved in children with cerebral palsy (CP), while the lower limb is more commonly affected. Little is known regarding the alterations in the upper limb kinematics after the orthopedic surgery of the lower extremity during gait. This study aimed to evaluate the differences in the upper limb kinematics in children with CP between preoperative and postoperative parameters.
To determine the effects of bilateral versus unilateral lower limb training on balance and gait parameters in stroke patients
Multiple sclerosis (MS) is the most common central nervous system inflammatory demyelinating disease which causes motor and sensory deficits, cerebellar symptoms, and balance problems. Due to these symptoms, gait abnormalities are common in MS, even in patients with low degrees of impairment. The upper limb has an important role on postural control and gait stability. Affected arm swing movement and asymmetry during gait are common in neurological disorders such as Parkinson's disease (PD) even in early stages of the disease and arm swing treatment has been acknowledged to enhance gait and normalize arm swing in individuals with PD. The presence of arm swing changes during walking in MS patients, similar to PD, especially in the early period, may be an indicator of balance problems, this was, however, not investigated as such. Therefore, the aim of the current study is to assess the arm swing during gait in people with MS shortly after their diagnosis in early MS.
Parkinson's Disease (PD) patients suffer from gait impairments responsible for falls and bad quality of life: reduced speed and stride length, randomness in the temporal organization of stride duration variability (reduced Long-Range Autocorrelations (LRA)). For years, auditory cueing has been used to modulate PD gait and its effect on LRA is known. Less is known regarding the effects of haptic cueing on PD gait and especially on LRA. This pilot study will compare the spatio-temporal gait parameters and LRA of PD patients tested under three conditions: walking without cueing, walking with auditory cueing and walking with haptic cueing by means of rhythmic vibrations on the patients' wrists.
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.
In this randomised placebo-controlled trial, the investigators will include 30 PD (Parkinson's disease) patients with HY (Hoehn Yahr stage) >2 and L-dopa unresponsive gait characteristics. Each participant will receive taVNS at 25Hz, taVNS at 100Hz and sham VNS (sVNS). During each stimulation, different gait characteristics will be measured with wearable insertion motion sensors.
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.
