In this paper, we present a wearable assistant for Parkinson's disease (PD) patients with the freezing of gait (FOG) symptom. This system uses on-body acceleration sensors to measure patients' movements. It automatically detects FOG by analyzing frequency components inherent in these When is detected, provides rhythmic auditory signal that stimulates patient resume walking. Ten PD tested while performing several walking tasks laboratory. More than 8 h data were recorded. Eight experienced...
Abstract Freezing of gait (FOG) is a disabling phenomenon common in patients with advanced Parkinson's disease (PD). The cause FOG unclear. objective this study was to explore novel hypothesis stating that related asymmetric motor performance. We compared PD experience episodes (PD+FOG) do not (PD−FOG) and studied the relationship asymmetry rhythmic hand movement performance determine whether potential FOG‐related unique walking or it systemic. Subjects were tested an “off” (unmedicated)...
Freezing of gait (FoG) is a common deficit in advanced Parkinson’s disease (PD). FoG events are associated with falls, interfere daily life activities and impair quality life. often resistant to pharmacologic treatment; therefore effective non-pharmacologic assistance needed.
Abstract Freezing of gait (FOG) in Parkinson's disease (PD) occurs most frequently during turns or step initiation, two tasks that likely demand a high degree bilateral coordination between the legs. Our objective was to test hypothesis impairments stepping are associated with FOG PD. We compared locomotion features while walking on level ground patients PD experience (PD + FOG; n = 21) and do not − 13). To study coordination, we defined stride duration one foot as cycle 360°, determined...
To develop an automated and objective method to assess mobility in Parkinson disease (PD) patients daily-life settings investigate whether accelerometer-derived measures discriminate between PD healthy controls as they walk simulate activities of daily living (ADL).Healthy older adults (17) with (22) wore a triaxial accelerometer on their lower back during short walks (validation study) around the medical center (ADL simulation). The variability (consistency rhythmicity) stepping was...
The Timed Up and Go (TUG) test is a widely used measure of mobility fall risk among older adults that typically scored using stopwatch. We tested the hypothesis body-fixed accelerometer can enhance ability TUG to identify community-living with relatively high unknown origin. Twenty-three elderly fallers (76.0 ± 3.9 years) 18 healthy controls (68.3 9.1 performed while wearing 3D-accelerometer on lower back. Acceleration-derived parameters included Sit-to-Stand Stand-to-Sit times, amplitude...
The aetiology of gait disturbances in Parkinson's disease (PD) is not fully understood. Recently, it was shown that patients with PD, bilateral coordination impaired and walking while being simultaneously engaged a cognitive task detrimental to their gait. To assess whether function influences the this study quantified left-right stepping using phase index (PCI) evaluates both variability inaccuracy (phi) generation (where ideal phi value between left right 180 degrees ). This report...
About 50% of the patients with advanced Parkinson's disease (PD) suffer from freezing gait (FOG), which is a sudden and transient inability to walk. It often causes falls, interferes daily activities significantly impairs quality life. Because deficits in PD are resistant pharmacologic treatment, effective non-pharmacologic treatments special interest.The goal our study evaluate concept wearable device that can obtain real-time data, processes them provides assistance based on pre-determined...
Several gait impairments have been associated with freezing of (FOG) in patients Parkinson's disease (PD). These include deteriorations rhythm control, symmetry, bilateral coordination gait, dynamic postural control and step scaling. We suggest that these seemingly independent features may mutual interactions which, during certain circumstances, jointly drive the predisposed locomotion system into a FOG episode. This new theoretical framework is illustrated by evaluation potential...
Ubiquity of Alzheimer's disease (AD) coupled with relatively ineffectual pharmacologic treatments has spurred interest in nonpharmacologic lifestyle interventions for prevention or risk reduction. However, evidence neuroplasticity notwithstanding, there are few scientifically rigorous, ecologically relevant brain training studies focused on building cognitive reserve middle age to protect against decline. This pilot study will examine the ability virtual reality (VR) improve cognition and...
The study of gait at self-selected speed is important. Traditional laboratories being relatively limited in space provide insufficient path length, while treadmill (TM) walking compromises natural by imposing variables. Self-paced (SP) can be realized on TM using feedback-controlled belt speed. We compared over ground vs. SP two experiments: without visual flow, and subjects were immersed a virtual reality (VR) environment inducing flow.Young healthy walked 96 meters comfortable speed, first...
Extensive research shows that virtual reality (VR) enhances motor learning and has advantages in balance gait rehabilitation of neurological patients. There is still uncertainty, however, as for the practicality efficacy VR long-term clinical routine. The objective this study was to report on 3 years practice conducting VR-based a large medical center.This retrospective systematically analyzed records patients who received center during years. We evaluated effect treatments gait, cognitive...
Freezing of gait (FOG) is a common deficit in advanced Parkinsonpsilas disease (PD). It often cause falls, interferes with daily activities and significantly impairs quality life. Gait deficits PD patients are resistant to pharmacologic treatment; therefore effective nonpharmacologic assistance needed. In this paper we show the potential context aware for FOG present our first results on start turn using modular wearable research platform. We developed real-time detection system which...
Healthy walking is characterized by pronounced arm swing and axial rotation. Aging effects on gait speed, stride length time variability have been previously reported, however, less known about aging rotation their relationship to age-associated changes during usual more challenging conditions like dual tasking. Sixty healthy adults between the ages of 30-77 were included in this study designed address gap. Lightweight body fixed sensors placed each wrist lower back. Participants walked...
Abstract Freezing of gait (FoG), a paroxysmal disturbance commonly experienced by patients with Parkinson’s disease (PD), is characterized sudden episodes inability to generate effective forward stepping. Recent studies have shown an increase in beta frequency local-field potentials the basal-ganglia during FoG, however, comprehensive research on synchronization between different brain locations and bands PD scarce. Here, developing tools based network science non-linear dynamics, we analyze...
