Comparison of Features for Movement Prediction From Single-trial Movement-related Cortical Potentials in Healthy Subjects and Stroke Patients
Kamavuako, EN; Jochumsen, M; Niazi, IK; Dremstrup, K (Hindawi Publishing Corporation, 2015)Detection of movement intention from the movement-related cortical potential (MRCP) derived from the electroencephalogram (EEG) signals has shown to be important in combination with assistive devices for effective neurofeedback ... -
Detecting and classifying three different hand movement types through electroencephalography recordings for neurorehabilitation
Jochumsen, M; Niazi, IK; Dremstrup, K; Kamavuako, EN (Springer, 2015)Brain–computer interfaces can be used for motor substitution and recovery; therefore, detection and classification of movement intention are crucial for optimal control. In this study, palmar, lateral and pinch grasps were ... -
An EEG Experimental Study Evaluating the Performance of Texas Instruments ADS1299
Rashid, U; Niazi, IK; Signal, N; Taylor, D (MDPI, 2018)Texas Instruments ADS1299 is an attractive choice for low cost electroencephalography (EEG) devices owing to its low power consumption and low input referred noise. To date, there have been no rigorous evaluations of its ... -
EEG Signatures Change During Unilateral Yogi Nasal Breathing
Niazi, IK; Navid, MS; Bartley, J; Shepherd, D; Pedersen, M; Burns, G; Taylor, D; White, DE (Springer Science and Business Media LLC, 2022)Airflow through the left-and-right nostrils is said to be entrained by an endogenous nasal cycle paced by both poles of the hypothalamus. Yogic practices suggest, and scientific evidence demonstrates, that right-nostril ... -
The Effects of 4 Weeks of Chiropractic Spinal Adjustments on Motor Function in People With Stroke: A Randomized Controlled Trial
Holt, K; Niazi, IK; Amjad, I; Kumari, N; Rashid, U; Duehr, J; Navid, MS; Shafique, M; Haavik, H (MDPI AG, 2021)Chiropractic spinal adjustments have been shown to result in short-term increases in muscle strength in chronic stroke patients, however, the effect of longer-term chiropractic spinal adjustments on people with chronic ... -
The Effects of Spinal Manipulation on Motor Unit Behavior
Robinault, L; Holobar, A; Crémoux, S; Rashid, U; Niazi, IK; Holt, K; Lauber, J; Haavik, H (MDPI AG, 2021)Over recent years, a growing body of research has highlighted the neural plastic effects of spinal manipulation on the central nervous system. Recently, it has been shown that spinal manipulation improved outcomes, such ... -
Efficacy of a Single-Task ERP Measure to Evaluate Cognitive Workload During a Novel Exergame
Ghani, U; Signal, N; Niazi, IK; Taylor, D (Frontiers Media, 2021)This study aimed to validate the efficacy of single-task event-related potential (ERP) measures of cognitive workload to be implemented in exergame-based rehabilitation. Twenty-four healthy participants took part in a novel ... -
Induction of long-term depression-like plasticity by pairings of motor imagination and peripheral electrical stimulation
Jochumsen, M; Signal, N; Nedergaard, RW; Taylor, D; Haavik, H; Niazi, IK (Frontiers Media S.A., 2015)Long-term depression (LTD) and long-term potentiation (LTP)-like plasticity are models of synaptic plasticity which have been associated with memory and learning. The induction of LTD and LTP-like plasticity, using ... -
Intra- and Inter-rater Reliability of Manual Feature Extraction Methods in Movement Related Cortical Potential Analysis
Alder, G; Signal, N; Rashid, U; Olsen, S; Niazi, IK; Taylor, D (MDPI, 2020)Event related potentials (ERPs) provide insight into the neural activity generated in response to motor, sensory and cognitive processes. Despite the increasing use of ERP data in clinical research little is known about ... -
Investigating the Intervention Parameters of Endogenous Paired Associative Stimulation (ePAS)
Alder, G; Signal, N; Vandal, AC; Olsen, S; Jochumsen, M; Niazi, IK; Taylor, DAdvances in our understanding of neural plasticity have prompted the emergence of neuromodulatory interventions, which modulate corticomotor excitability (CME) and hold potential for accelerating stroke recovery. Endogenous ... -
