Filter by:Stroke is a prevalent global health concern, causing widespread disability as it disrupts blood supply to the brain, leading to functional impairments. Upper limb dysfunction affects over 80% of stroke survivors acutely and becomes permanent in approximately 60%, hindering daily activities and autonomy. Dual-task training (DTT), involving simultaneous cognitive and motor tasks resembling daily activities, is proposed as an effective intervention. The study suggests using electroencephalogram (EEG) analysis, particularly the Fast Fourier Transform (FFT), to assess changes in brain signals pre- and post-DTT intervention. EEG provides real-time insights into brain function, and FFT analyzes signal frequencies. The intervention involves three tasks performed concurrently with mental calculations, such as sorting blocks and manipulating objects. This 12-session, four-week intervention aims to improve upper limb function. The study explores EEG's role in evaluating DTT effects on stroke patients, particularly using FFT to analyze brain signal frequencies.
This study investigates the modification of the local-to-global connectivity pattern in response to experimental heat pain. Transcranial magnetic stimulation (TMS) will be applied to elicit electroencephalography (EEG) responses in healthy volunteers. The TMS-evoked potentials (TEPs) will be recorded and serve as a reflection of cortical reactivity to TMS. A thermal cutaneous heat stimulus will induce painful sensations.
Electroencephalogram (EEG) has an important place in establishing the correct diagnosis, providing appropriate intervention, and predicting the prognosis in the long term in children. When the literature is examined, it is seen that different sedative drugs (benzodiazepines, barbiturates, phenothiazine, chloral hydrate, hydroxyzine, melatonin, etc.) and their combinations are used to provide sedation during EEG recordings, but there is no ideal sedative drug. Nurses working in the field of pediatric neurology in EEG recordings; It has important roles in preparing the child and parent for the procedure, applying sedation before the procedure, performing the EEG recording properly, monitoring vital signs during the procedure, monitoring the effects of the sedative substance after the procedure, and sending the patient home safely. Pediatric nurses fulfill these roles by adopting a multidisciplinary team approach. In this context, the aim of our research is; The aim of this study is to evaluate the effects of chloral hydrate, hydroxyzine and melatonin, which are used as sedative agents before EEG recording in children, on sleep success, time to fall asleep, side effects and EEG background.
The athlete population has a high risk of suffering from mental health problems (e.g., anxiety), especially for athletes with individual sports. As such, various forms of mental training were used to maintain the mental health of athletes, such as mindfulness training or relaxation training. However, differences pertaining to the electrophysiological mechanisms resulting from both mental training in athletes are unknown. Therefore, the purpose of the current study was to examine the differential effects between the brief mindfulness induction (MI) and relaxation induction (RI) on state anxiety, affect and the activation of the brain in track and field athletes.
With the development of science and technology, there are more and more electromagnetic and noise factors in the working and living environment. These two factors often exist together, and their impact on people may interact. Scalp EEG is a classic nerve detection technology, which can reflect the functional state of the brain in a non-invasive and real-time manner. This project intends to use EEG technology to study the effects of electromagnetism and noise on human brain function.
The investigators aimed to divide the healthy individuals aged between 18-45 years, included in our study, into three groups as bilateral, unilateral-right and unilateral-left Auricular Vagus Nerve Stimulation (VNS). The investigators planned to examine the effects of vagal nerve stimulation applied to each group with superficial EMG and EEG measurements before and after. Auricular vagus nerve stimulation has effects on cerebral activity. Therefore, this effect will be evaluated with EEG. In addition, whether there is a secondary peripheral effect will be examined by EMG method. Changes to be detected in EEG and EMG in healthy individuals may give an idea about the use of auricular vagus nerve stimulation in patients. In this study, healthy individuals between the ages of 18-45, who do not have any chronic diseases and who do not have to use any medication regularly will be included in all three groups. Due to the superficial EMG measurement method the investigators used, those who have orthopedic problems in the upper extremity (shoulder, elbow, wrist and fingers) or have a history of surgical operation in the upper extremity, however, any systemic disease such as diabetes, gout, chronic kidney failure, rheumatoid arthritis, thyroid diseases individuals will be excluded from the study in all three groups.
Our recent preclinical observations suggest that monitoring of slow electroencephalogram (EEG) oscillations may be used to predict the efficacy of rapid-acting antidepressants such as ketamine or nitrous oxide. In this project we will carry out critical clinical research on healthy volunteers and study the effects of nitrous oxide on EEG. Results will be used for the design of clinical trials on depressed individuals. The project will be done in collaboration between neuroscientists at the University of Helsinki and clinicians at the Tampere University Hospital.
The aim of this study is to describe the BIS values and electroencephalographic patterns during total intravenous anesthesia with propofol-remifentanyl, in patients from 18 to 85 years.
The aim of the study is to compare the effect of melatonin, given orally, dexmedetomidine, given intranasally, and dexmedetomidine given sublingually on sleep induction, sleep duration, their possible impact on vital functions and technical implementation of EEG.
The first objective of this work is to compare the performances of three electroencephalogram based indices, the qCON index, the qNOX index and the bispectral index (BIS), in patients receiving gastrointestinal surgery during first postoperative night. Secondly, their behaviors under general anesthesia are also pointed out. The qCON and qNOX indices are implemented in an Angel 6000 monitor (WellHealth Medical Co Ltd., Shenzhen, China), and BIS indices are recorded in a BIS monitor (Aspect Medical Systems, Norwood, MA, USA). Data will be obtained from 30 patients scheduled for selective surgery undergoing general anesthesia with a combination of propofol, sufentanil and cis-atracurium in the first Hospital of China Medical University. The values of qCON, qNOX and BIS were statistically compared. The qCON, qNOX indices are recorded together with BIS during the whole operation period (Awake- Anesthesia-Recovery stages), as well as during the first night postoperatively (from 8:00pm to 06:00am). The values of qCON, qNOX and BIS were statistically compared. The Consistency evaluation will be conducted between qCON/qNOX and BIS.
