Background and aims Polycystic ovary syndrome (PCOS) and type 1 diabetes are relatively common endocrinopathies, often manifesting across most of the lifespan. Cardiovascular risk is increased in both PCOS and type 1 diabetes, affecting patients' …
Background: Hypertension has adverse effects on microvascular function but there are limited methods that permit non-invasive assessment of the microcirculation in man in vivo. We used Near Infrared Spectroscopy (NIRS) to assess microvascular …
Metabolic inflexibility is an emerging physiological marker indicative of metabolic dysfunction and associated with type 2 diabetes (T2D) and obesity. Exercise is a potent stimulus to improve metabolic health, however, not much is known about the …
In most daily activities related to work or leisure, the energy for muscle work substantially comes from oxidative metabolism. Functional limitations or impairments of this metabolism can significantly affect exercise tolerance and performance. As a …
Objective: At this moment, a wake-up test needs to be done when amplitudes of TES-MEP monitoring decrease irreversible during scoliosis surgery, what mostly turns out to be a false-positive. To make TES-MEP measurements more reliable, we need to know …
Background: Multiple sclerosis is a demyelinating disorder that impacts mobility and function. The benefits of exercise on multiple sclerosis symptoms have been demonstrated. Exercise is proven to increase cerebral blood flow, and improve oxygen …
Musculoskeletal pain is one of the most common causes of chronic pain. Exercise- based pain management programs have been suggested as an effective alternative for relieving from musculoskeletal pain; however the pain which is experienced after …
Introduction: The ability to walk safely and independently is a fundamental component of daily living activities. Walking while dual tasking and obstacle negotiation are two tasks that have been used to investigate walking in complex situations. …
Near Infrared Spectroscopy is a method that measures the brain's haemodynamic response. It is of interest in brain-computer interfaces where haemodynamic patterns in motor tasks are exploited to detect movement. However, the NIRS signal is usually …
Introduction: Oxygen consumption during prolonged cycling exercise has been extensively studied at different work rates and durations, but with the focus primarily on pulmonary oxygen consumption (pVO2). The purpose of this study was to use …
Working memory is sensitive to aging-related decline. Evidence exists that aging is accompanied by a reorganization of the working-memory circuitry, but the underlying neurocognitive mechanisms are unclear. In this study, we examined aging-related …
PURPOSE: Evaluation of skeletal muscle oxidative capacity in people with multiple sclerosis (MS) using near-infrared spectroscopy (NIRS) and its relationship with measures of walking disability. METHODS: Muscle oxidative capacity was measured in an …
For adequate development and functioning of the neonatal brain, sufficient oxygen (O2) should be available. With a fast sampling (fs 50 Hz) continuous wave NIRS device, arterial (SaO2) and venous (SvO2) saturation can be measured using the …
The aim of this study was to investigate the performance of in vivo quantitative near- infrared spectroscopy (NIRS) in skeletal muscle at various workloads. NIRS was used for the quantitative measurement of O2 consumption (m _VO2) in the human flexor …
A short history of oximetry During the second half of the 19th century it was discovered that blood cells contain a colouring substance whose spectrum is influenced by various blood gases [Hoppe, 1862]. Stokes discovered that this coloured substance …
