A robust machine learning enabled decomposition of shear ground reaction forces during the double contact phase of walking.
Gait & posture
Jul 9, 2019
BACKGROUND: Dynamic analyses of walking rely on the 3D ground reaction forces (GRF) under each foot, while only the resultant force of both limbs may be recorded on a single-belt instrumented treadmill or when both feet touch the same force platform.
Single Inertial Sensor-Based Neural Networks to Estimate COM-COP Inclination Angle During Walking.
Sensors (Basel, Switzerland)
Jul 5, 2019
A biomechanical understanding of gait stability is needed to reduce falling risk. As a typical parameter, the COM-COP (center of mass-center of pressure) inclination angle (IA) could provide valuable insight into postural control and balance recovery...
Metabolic cost adaptations during training with a soft exosuit assisting the hip joint.
Scientific reports
Jul 5, 2019
Different adaptation rates have been reported in studies involving ankle exoskeletons designed to reduce the metabolic cost of their wearers. This work aimed to investigate energetic adaptations occurring over multiple training sessions, while walkin...
Effect of EMG-biofeedback robotic-assisted body weight supported treadmill training on walking ability and cardiopulmonary function on people with subacute spinal cord injuries - a randomized controlled trial.
BMC neurology
Jun 24, 2019
BACKGROUND: Body weight supported treadmill training (BWSTT) is a frequently used approach for restoring the ability to walk after spinal cord injury (SCI). However, the duration of BWSTT is usually limited by fatigue of the therapists and patients. ...
Rapid energy expenditure estimation for ankle assisted and inclined loaded walking.
Journal of neuroengineering and rehabilitation
Jun 6, 2019
BACKGROUND: Estimating energy expenditure with indirect calorimetry requires expensive equipment and several minutes of data collection for each condition of interest. While several methods estimate energy expenditure using correlation to data from w...
A force-measuring and behaviour-recording system consisting of 24 individual 3D force plates for the study of single limb forces in climbing animals on a quasi-cylindrical tower.
Bioinspiration & biomimetics
May 24, 2019
This study describes the design of a new force measuring array with a quasi-cylindrical surface for measuring the 3D ground reaction forces of animals climbing on a surface with high curvature. This force-measuring array was assembled from 24 individ...
See your mental state from your walk: Recognizing anxiety and depression through Kinect-recorded gait data.
PloS one
May 22, 2019
As the challenge of mental health problems such as anxiety and depression increasing today, more convenient, objective, real-time assessing techniques of mental state are in need. The Microsoft Kinect camera is a possible option for contactlessly cap...
Self-supervised learning of the biologically-inspired obstacle avoidance of hexapod walking robot.
Bioinspiration & biomimetics
May 3, 2019
In this paper, we propose an integrated biologically inspired visual collision avoidance approach that is deployed on a real hexapod walking robot. The proposed approach is based on the Lobula giant movement detector (LGMD), a neural network for loom...
Methodology and validation for identifying gait type using machine learning on IMU data.
Journal of medical engineering & technology
Apr 30, 2019
With the rising popularity of activity tracking, there is a desire to not only count the number of steps a person takes, but also identify the type of step (e.g., walking or running) they are taking. For rehabilitation and athletic training, this dif...
Combining Haptic and Bang-Bang Braking Actions for Passive Robotic Walker Path Following.
IEEE transactions on haptics
Apr 26, 2019
Robotic walkers are a promising solution for physical and cognitive support to older adults. This paper proposes a low cost path following strategy combining the advantages of a simple mechanical braking guidance, such as safety, passivity, and a low...
