The effect of short time computer work on muscle oxygenation in presence of delayed onset muscle soreness

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 …

Optimization measurement of muscle oxygen saturation under isometric studies using FNIRS

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 …

Is wireless functional near-infrared spectroscopy (fNIRS) 3D neuroimaging feasible to map human navigation in the real-world?

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 …

Towards NIRS-based hand movement recognition

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 …

The effect of mental fatigue on sustained attention: an fNIRS study

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 …

The investigation of brain-computer interface for motor imagery and execution using functional near-infrared spectroscopy

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 …

Investigating deep learning for fNIRS based BCI

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 …

Optical diagnosis of acute scrotum in children

© 2015 SPIE.Background: Acute scrotum is a urologic condition defined by scrotal pain, swelling, and redness of acute onset. Prompt diagnosis and treatment are necessary to preserve testicular viability. The history and clinical symptoms reported are …

Optical diagnosis of testicular torsion: feasibility and methodology

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 …

Classification of mental tasks in the prefrontal cortex using fNIRS

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, …

Optical diagnosis of interstitial cystitis / painful bladder syndrome

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 …

Towards Biometric Person Identification using fNIRS

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 …

Measuring workload using a combination of electroencephalography and near infrared spectroscopy

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 …

Monitoring of lower urinary tract function in patients with spinal cord injury using near infrared spectroscopy

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 …

Attenuation of motion artifact in near infrared spectroscopy signals using a wavelet based method

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 …

Do radio frequencies of medical instruments common in the operating room interfere with near-infrared spectroscopy signals?

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 …
