We aimed at investigating the effect of a short time low load repetitive task on the local muscle oxygenation kinetics in presence of delayed onset muscle soreness. Computer work was investigated as a model of low load repetitive task. Nine healthy …
Development of functional near infrared spectroscopy (fNIRS) technologies has advanced quantification signal using multiple wavelength and detector to investigate hemodynamic response in human muscle. These non-invasive technologies have been widely …
Real-time maps (with temporal and spatial resolution: 1–10 Hz and $∼$1 cm, respectively) of cortical activation can be obtained by functional near-infrared spectroscopy (fNIRS), which noninvasively measures cortical hemodynamic changes (as oxygenated …
This work reports on preliminary results about on hand movement recognition with Near InfraRed Spectroscopy (NIRS) and surface ElectroMyoGraphy (sEMG). Either basing on physical contact (touchscreens, data-gloves, etc.), vision techniques (Microsoft …
Sustained attention is the ability to keep focused and vigilance for long time in external stimulation, which was crucial in safe-critical human-machine system. While the ability of sustained attention will decline because of mental fatigue, even …
Functional near-infrared spectroscopy (fNIRS), which can measure cortex hemoglobin activity, has been widely adopted in brain-computer interface (BCI). To explore the feasibility of recognizing motor imagery (MI) and motor execution (ME) in the same …
Functional Near infrared Spectroscopy (fNIRS) is a relatively young modality for measuring brain activity which has recently shown promising results for building Brain Computer Interfaces (BCI). Due to its infancy, there are still no standard …
Background: Torsion of the testis compromises blood flow through the spermatic cord; testicular ischemia results which if not diagnosed promptly and corrected surgically irrevocably damages the testis. Current diagnostic modalities aimed at …
Functional near infrared spectroscopy (fNIRS) is rapidly gaining interest in both the Neuroscience, as well as the Brain-Computer-Interface (BCI) community. Despite these efforts, most single-trial analysis of fNIRS data is focused on motor-imagery, …
Background: Painful bladder syndrome/interstitial cystitis (PBS/IC) is defined as a syndrome of urgency, frequency, and suprapubic pain in the absence of positive urine culture or obvious bladder pathology. As no specific etiology has been identified …
We investigate the potential of using fNIRS signals for biometric person identification. Independent sessions for training and testing have been recorded using 8 channels of frontal fNIRS. We extract logarithmic power spectral densities as features …
The ability to continuously monitor workload in a real-world environment would have important implications for the offline design of human machine interfaces as well as the real-time improvement of interaction between humans and machines. We explored …
Background: One of the most important conditions where there is loss of normal bladder function is spinal cord injury (SCI). Currently, evaluation of bladder function is limited to periodic invasive urodynamic testing (UDS). The purpose of this study …
The sensitivity of Near Infrared Spectroscopy (NIRS) signals to motion artifact can limit practical applications of NIRS monitoring. We describe a wavelet based method for removing motion artifact from NIRS signals. This method was tested on …
Background:Medical and diagnostic applications of near infrared spectroscopy (NIRS) areincreasing, especially in operating rooms (OR). Since NIRS is anoptical technique, radio frequency (RF) interference from other instruments isunlikely to affect …
Background: Continuous wave near-infrared spectroscopy (NIRS) can monitor chromophore change in the bladder detrusor muscle during voiding; oxygenation and hemodynamic data derived differ in health and disease. Application of wireless NIRS for …
The monitoring of a single muscle location does not reflect the heterogeneity of the muscle groups activation during exercise. In the past, measurements of oxygen consumption (VO2) at single muscle locations could be carried out non-invasively by …
