O 089 - A soft robotic exosuit assisting the paretic ankle in patients post-stroke: Effect on muscle activation during overground walking.
Gait & posture
Jun 26, 2018
This study compared overground walking with and without exosuit assistance in post-stroke patients. Exosuit-assisted walking was found to improve paretic propulsion and ground clearance during swing, two common gait deviations in stroke patients. No ...
Reliability, validity, and clinical feasibility of a rapid and objective assessment of post-stroke deficits in hand proprioception.
Journal of neuroengineering and rehabilitation
Jun 7, 2018
BACKGROUND: Proprioceptive function can be affected after neurological injuries such as stroke. Severe and persistent proprioceptive impairments may be associated with a poor functional recovery after stroke. To better understand their role in the re...
Ischemic stroke lesion segmentation using stacked sparse autoencoder.
Computers in biology and medicine
Jun 2, 2018
Automatic segmentation of ischemic stroke lesion volumes from multi-spectral Magnetic Resonance Imaging (MRI) sequences plays a vital role in quantifying and locating the lesion region. Most existing methods mainly rely on designing hand-crafted feat...
Effects of robot-assisted gait training in chronic stroke patients treated by botulinum toxin-a: A pivotal study.
Physiotherapy research international : the journal for researchers and clinicians in physical therapy
May 28, 2018
OBJECTIVE: To investigate combined effects of robot-assisted training (RAT) and physical therapy versus physical therapy only on balance and gait function of chronic stroke patients after botulinum toxin-A (BoNT-A) treatment.
Reshaping Movement Distributions With Limit-Push Robotic Training.
IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society
May 21, 2018
High-cost situations need to be avoided. However, occasionally, cost may only be learned by experience. Here, we tested whether an artificially induced unstable and invisible high-cost region, a "limit-push" force field, might reshape people's motion...
Reliability, validity and discriminant ability of the instrumental indices provided by a novel planar robotic device for upper limb rehabilitation.
Journal of neuroengineering and rehabilitation
May 16, 2018
BACKGROUND: In the last few years, there has been an increasing interest in the use of robotic devices to objectively quantify motor performance of patients after brain damage. Although these robot-derived measures can potentially add meaningful info...
Prediction of Tissue Outcome and Assessment of Treatment Effect in Acute Ischemic Stroke Using Deep Learning.
Stroke
May 2, 2018
BACKGROUND AND PURPOSE: Treatment options for patients with acute ischemic stroke depend on the volume of salvageable tissue. This volume assessment is currently based on fixed thresholds and single imagine modalities, limiting accuracy. We wish to d...
Evolution of upper limb kinematics four years after subacute robot-assisted rehabilitation in stroke patients.
The International journal of neuroscience
Apr 25, 2018
To assess functional status and robot-based kinematic measures four years after subacute robot-assisted rehabilitation in hemiparesis. Twenty-two patients with stroke-induced hemiparesis underwent a ≥3-month upper limb combined program of robot-ass...
Classifying Acute Ischemic Stroke Onset Time using Deep Imaging Features.
AMIA ... Annual Symposium proceedings. AMIA Symposium
Apr 16, 2018
Models have been developed to predict stroke outcomes (e.g., mortality) in attempt to provide better guidance for stroke treatment. However, there is little work in developing classification models for the problem of unknown time-since-stroke (TSS), ...
Automatic Segmentation of Acute Ischemic Stroke From DWI Using 3-D Fully Convolutional DenseNets.
IEEE transactions on medical imaging
Mar 30, 2018
Acute ischemic stroke is recognized as a common cerebral vascular disease in aging people. Accurate diagnosis and timely treatment can effectively improve the blood supply of the ischemic area and reduce the risk of disability or even death. Understa...
