Physiological responses and perceived exertion during robot-assisted treadmill walking in non-ambulatory stroke survivors.
Disability and rehabilitation
Oct 7, 2019
PURPOSE: To examine physiological responses and perceived exertion during robot-assisted treadmill walking in non-ambulatory stroke survivors; compare these outcomes with aerobic exercise recommendations; and investigate the effect of robotic assista...
Fore-aft resistance applied at the center of mass using a novel robotic interface proportionately increases propulsive force generation in healthy nonimpaired individuals walking at a constant speed.
Journal of neuroengineering and rehabilitation
Sep 6, 2019
BACKGROUND: Past studies have utilized external interfaces like resistive bands and motor-generated pulling systems to increase limb propulsion during walking on a motorized treadmill. However, assessing changes in limb propulsion against increasing ...
Physiological Responses and Perceived Exertion During Robot-Assisted and Body Weight-Supported Gait After Stroke.
Neurorehabilitation and neural repair
Nov 12, 2018
INTRODUCTION: Physiological responses are rarely considered during walking after stroke and if considered, only during a short period (3-6 minutes). The aims of this study were to examine physiological responses during 30-minute robot-assisted and bo...
Relationships Between the External and Internal Training Load in Professional Soccer: What Can We Learn From Machine Learning?
International journal of sports physiology and performance
May 22, 2018
PURPOSE: Machine learning may contribute to understanding the relationship between the external load and internal load in professional soccer. Therefore, the relationship between external load indicators (ELIs) and the rating of perceived exertion (R...
Classifying work rate from heart rate measurements using an adaptive neuro-fuzzy inference system.
Applied ergonomics
Jan 2, 2016
In a new approach based on adaptive neuro-fuzzy inference systems (ANFIS), field heart rate (HR) measurements were used to classify work rate into four categories: very light, light, moderate, and heavy. Inter-participant variability (physiological a...
Predicting workload profiles of brain-robot interface and electromygraphic neurofeedback with cortical resting-state networks: personal trait or task-specific challenge?
Journal of neural engineering
Jul 14, 2015
OBJECTIVE: Novel rehabilitation strategies apply robot-assisted exercises and neurofeedback tasks to facilitate intensive motor training. We aimed to disentangle task-specific and subject-related contributions to the perceived workload of these inter...
Characterization of running with compliant curved legs.
Bioinspiration & biomimetics
Jul 7, 2015
Running with compliant curved legs involves the progression of the center of pressure, the changes of both the leg's stiffness and effective rest length, and the shift of the location of the maximum stress point along the leg. These phenomena are pro...
Towards highly-tuned mobility in multiple domains with a dynamical legged platform.
Bioinspiration & biomimetics
Jun 16, 2015
As mobile robots become more commonly utilized in everyday applications, the tasks they are given will often require them to quickly traverse unprepared and varied environments. While traditional mobile platforms may falter under such conditions, ani...
Evaluating the User Experience of Exercising Reaching Motions With a Robot That Predicts Desired Movement Difficulty.
Journal of motor behavior
May 6, 2015
The notion of an optimal difficulty during practice has been articulated in many areas of cognitive psychology: flow theory, the challenge point framework, and desirable difficulties. Delivering exercises at a participant's desired difficulty has the...
Quadrupedal galloping control for a wide range of speed via vertical impulse scaling.
Bioinspiration & biomimetics
Mar 25, 2015
This paper presents a bio-inspired quadruped controller that allows variable-speed galloping. The controller design is inspired by observations from biological runners. Quadrupedal animals increase the vertical impulse that is generated by ground rea...
