- Conference
mNIRS 2026 opens in Pavia
The second international muscle NIRS meeting runs from 17 to 19 September at the University of Pavia, with three days of science, sponsor demonstrations and applied discussion.

mnirs.org has a new look
The site has been redesigned ahead of Pavia. The conference archive, video library and partner list are all still here.

Welcome to MuscleNIRS
Muscle near infrared spectroscopy (mNIRS) has developed enormously since Frans Jöbsis first demonstrated in 1977 that near infrared light could be used to monitor…

Measuring oxygen saturation using other Multi-Distance Methods
Methods other than SRS use multiple source–detector distances to estimate StO₂. While the methods vary, a shared principle is that shorter distances sample more…

Measuring oxygen saturation using Spatially Resolved Spectroscopy (SRS)
There are methods for measuring absolute muscle tissue oxygen saturation (StO₂) that do not require expensive time-domain or frequency-domain systems. One such…

Measuring oxygen saturation by physiological calibration
This simple approach can be applied to almost any mNIRS system. The principle is to expose the muscle to physiological conditions that produce a minimum and maximum…

Measuring absolute heme concentrations
Whilst all mNIRS devices can in principle measure changes in oxy and deoxy heme concentrations, more expensive equipment is needed to measure absolute…

Measuring changes in heme concentration
Early mNIRS measurements were reported in “arbitrary units” or used a “physiological calibration” (see later method). David Delpy and colleagues, together with…

The first mNIRS
Near infrared light (700–1,000 nm) can penetrate tissue because of the relatively low absorbance of biological chromophores in this wavelength range. However, those…
