Effects of a wearable exoskeleton stride management assist system (SMA®) on spatiotemporal gait characteristics in individuals after stroke: a randomized controlled trial.
Journal of neuroengineering and rehabilitation
Aug 20, 2015
BACKGROUND: Robots offer an alternative, potentially advantageous method of providing repetitive, high-dosage, and high-intensity training to address the gait impairments caused by stroke. In this study, we compared the effects of the Stride Manageme...
Design, testing and modelling of a novel robotic system for trans-oesophageal ultrasound.
The international journal of medical robotics + computer assisted surgery : MRCAS
Jul 31, 2015
BACKGROUND: Trans-oesophageal echocardiography (TOE) has been widely utilized for cardiac disease diagnosis and interventional procedure guidance. However, the TOE operator is required to manually manipulate the probe, often for long periods of time ...
Simulation-Based Design for Wearable Robotic Systems: An Optimization Framework for Enhancing a Standing Long Jump.
IEEE transactions on bio-medical engineering
Jul 30, 2015
GOAL: Technologies that augment human performance are the focus of intensive research and development, driven by advances in wearable robotic systems. Success has been limited by the challenge of understanding human-robot interaction. To address this...
Dynamic modeling of breast tissue with application of model reference adaptive system identification technique based on clinical robot-assisted palpation.
Journal of the mechanical behavior of biomedical materials
Jul 29, 2015
Accurate identification of breast tissue's dynamic behavior in physical examination is critical to successful diagnosis and treatment. In this study a model reference adaptive system identification (MRAS) algorithm is utilized to estimate the dynamic...
Human upper-limb force capacities evaluation with robotic models for ergonomic applications: effect of elbow flexion.
Computer methods in biomechanics and biomedical engineering
Jul 27, 2015
The aim of this study was to apply models derived from the robotics field to evaluate the human upper-limb force generation capacity. Four models were compared: the force ellipsoid (FE) and force polytope (FP) based on unit joint torques and the scal...
Robot-aided in vitro measurement of patellar stability with consideration to the influence of muscle loading.
Biomedical engineering online
Jul 23, 2015
BACKGROUND: Anterior knee pain is often associated with patellar maltracking and instability. However, objective measurement of patellar stability under clinical and experimental conditions is difficult, and muscular activity influences the results. ...
Robotic therapy for chronic stroke: general recovery of impairment or improved task-specific skill?
Journal of neurophysiology
Jul 15, 2015
There is a great need to develop new approaches for rehabilitation of the upper limb after stroke. Robotic therapy is a promising form of neurorehabilitation that can be delivered in higher doses than conventional therapy. Here we sought to determine...
An experimental comparison of the relative benefits of work and torque assistance in ankle exoskeletons.
Journal of applied physiology (Bethesda, Md. : 1985)
Jul 9, 2015
Techniques proposed for assisting locomotion with exoskeletons have often included a combination of active work input and passive torque support, but the physiological effects of different assistance techniques remain unclear. We performed an experim...
Predicting Complete Ground Reaction Forces and Moments During Gait With Insole Plantar Pressure Information Using a Wavelet Neural Network.
Journal of biomechanical engineering
Jul 1, 2015
In general, three-dimensional ground reaction forces (GRFs) and ground reaction moments (GRMs) that occur during human gait are measured using a force plate, which are expensive and have spatial limitations. Therefore, we proposed a prediction model ...
Quantification of loading in biomechanical testing: the influence of dissection sequence.
Journal of biomechanics
Jun 26, 2015
Sequential dissection is a technique used to investigate loads experienced by articular tissues. When the joint of interest is tested in an unconstrained manner, its kinematics change with each tissue removal. To address this limitation, sufficiently...
