PLoS ONE, 2014 • October 27, 2014
This study investigates the use of human walking data to control the gait of a bipedal robot, RunBot II, by establishing a causal relationship between foot contact and muscle activity. Adaptive filter...
KEY FINDING: There is a causal relationship between ground contact information from the heel and EMG, which allows the creation of a minimal, linear, analogue control system for controlling walking.
Journal of NeuroEngineering and Rehabilitation, 2014 • November 15, 2014
This paper investigates the possibility of building decoders for seven upper-limb analytic movements using pre-movement EEG correlates with healthy subjects and tests the decoders in a clinical enviro...
KEY FINDING: Movement intention can be decoded from EEG signals for seven different upper-limb analytic movements.
Med Eng Phys, 2014 • December 1, 2014
This study presents a novel framework for suppressing the effects of the involuntary background spikes by combining a Wiener filter [4] and a priori SNR estimation via the decision-directed method (us...
KEY FINDING: After the processing, the onset detection of voluntary muscle activity was significantly improved against involuntary background spikes.
Neurobiol Dis, 2015 • November 1, 2015
This review discusses the potential of combining Functional Electrical Stimulation (FES) and Brain-Machine Interfaces (BMIs) to restore motor function in paralyzed individuals. Current FES systems are...
KEY FINDING: FES can improve muscle strength, range of motion, and potentially reduce spasticity, leading to benefits like improved cardiopulmonary function, bone strengthening, and pressure sore relief.
Frontiers in Neuroengineering, 2014 • November 18, 2014
This special issue highlights the interaction of BCI systems with underlying neurological problems, showcasing how their performance differs from systems tested on healthy individuals. The collection ...
KEY FINDING: BCI-HK group achieved significantly larger motor gain than the other two groups, when compared to hand and arm rehabilitation therapies, BCI with a haptic knob (HK) robot, HK alone or a standard physiotherapy.
J. Synchrotron Rad., 2015 • January 1, 2015
This study investigates the use of X-ray phase-contrast CT imaging to visualize the microstructure and degradation of biodegradable scaffolds implanted in injured spinal cords. The imaging technique s...
KEY FINDING: X-ray phase-contrast CT imaging can visualize the microstructure of a scaffold, including the hollow tubular structure and PGA microfibres, after implantation into an injured spinal cord.
Frontiers in Neuroscience, 2016 • August 3, 2016
This paper presents an integrated system for the closed-loop control of an ambulatory exoskeleton with a BMI. The exoskeleton works under an assist-as-needed control paradigm, which can be adapted to ...
KEY FINDING: For the three healthy subjects, 84.44 ± 14.56% of the trials were correctly decoded, indicating the viability of the setup.
Journal of NeuroEngineering and Rehabilitation, 2015 • January 21, 2015
This study explores the potential of using Functional Neuromuscular Stimulation (FNS) to maintain seated balance in individuals with spinal cord injury (SCI). A feedback control system was designed to...
KEY FINDING: The controller could maintain trunk stability in the sagittal plane for perturbations up to 45% of body weight and for flexion thresholds as low as 0.7.
Med Biol Eng Comput, 2018 • July 24, 2017
This study investigated feedback control of FNS for stabilizing standing postures after SCI, including erect and leaning positions. Perturbations were applied to subjects with SCI using FNS, and the e...
KEY FINDING: Feedback control reduced the need for upper extremity (UE) force by up to 50% in some leaning postures.
Scientific Reports, 2016 • September 19, 2016
This study introduces a new method for providing lower limb somatosensory feedback to paraplegic patients by remapping tactile sensations to their forearms using a haptic display and virtual reality. ...
KEY FINDING: SCI patients could perceive the position of a virtual leg during locomotion using tactile feedback on their forearms.
