Effect of forward-directed aiding force on gait mechanics in healthy young adults while walking faster.
Gait & posture
May 18, 2018
BACKGROUND: Forces can be applied to people while they are walking on a treadmill in different ways that aid individuals to walk at faster walking speeds with potentially less effort. Forward-directed aiding forces (FAF) are a special class of aiding...
Encoding of Articulatory Kinematic Trajectories in Human Speech Sensorimotor Cortex.
Neuron
May 17, 2018
When speaking, we dynamically coordinate movements of our jaw, tongue, lips, and larynx. To investigate the neural mechanisms underlying articulation, we used direct cortical recordings from human sensorimotor cortex while participants spoke natural ...
Recovery and compensation after robotic assisted gait training in chronic stroke survivors.
Disability and rehabilitation. Assistive technology
May 9, 2018
Gait re-education is a primary rehabilitation goal after stroke. In the last decades, robots with different mechanical structures have been extensively used in the clinical practice for gait training of stroke survivors. However, the effectiveness o...
Effects of Proud Large Osteochondral Plugs on Contact Forces and Knee Kinematics: A Robotic Study.
The American journal of sports medicine
May 9, 2018
BACKGROUND: Osteochondral allograft (OCA) transplantation is used to treat large focal femoral condylar articular cartilage defects. A proud plug could affect graft survival by altering contact forces (CFs) and knee kinematics.
Automated assessment of levodopa-induced dyskinesia: Evaluating the responsiveness of video-based features.
Parkinsonism & related disorders
May 5, 2018
INTRODUCTION: Technological solutions for quantifying Parkinson's disease (PD) symptoms may provide an objective means to track response to treatment, including side effects such as levodopa-induced dyskinesia. Vision-based systems are advantageous a...
Feedback Control-Based Navigation of a Flying Insect-Machine Hybrid Robot.
Soft robotics
May 3, 2018
This study reports the first ever demonstration of the aero navigation of a free-flying insect based on feedback control. Instead of imitating the complicated kinetics and mechanisms of insect locomotion, a live insect can be directly transformed int...
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...
Predicting net joint moments during a weightlifting exercise with a neural network model.
Journal of biomechanics
Apr 25, 2018
The purpose of this study was to develop and train a Neural Network (NN) that uses barbell mass and motions to predict hip, knee, and ankle Net Joint Moments (NJM) during a weightlifting exercise. Seven weightlifters performed two cleans at 85% of th...
Design and evaluation of a deformable wing configuration for economical hovering flight of an insect-like tailless flying robot.
Bioinspiration & biomimetics
Apr 18, 2018
Studies on wing kinematics indicate that flapping insect wings operate at higher angles of attack (AoAs) than conventional rotary wings. Thus, effectively flying an insect-like flapping-wing micro air vehicle (FW-MAV) requires appropriate wing design...
Design and analysis of coiled fiber reinforced soft pneumatic actuator.
Bioinspiration & biomimetics
Apr 18, 2018
Fiber reinforced elastomeric enclosures (FREEs) are soft pneumatic actuators that can contract and generate forces upon pressurization. Typical engineering applications utilize FREEs in their straight cylindrical configuration and derive actuation di...
