Oyanagi K, Kitai T, Yoshimura Y, Yokoi Y, Ohara N, Kohara N, et al.
Geriatr Gerontol Int . 2021 Jun; 21(8):623-628. PMID: 34101957
Aim: Intensive rehabilitation effectively improves physical functions in patients with acute stroke, but the frequency of intervention and its cost-effectiveness are poorly studied. This study aimed to examine the effect...

Oyanagi K, Tsubaki A
Respir Physiol Neurobiol . 2021 May; 291:103691. PMID: 33992799
This study aimed to examine whether the end-tidal partial pressure of CO (PEtCO) affects the concentration of oxygenated hemoglobin (OHb) measured by near-infrared spectroscopy (NIRS). Participants were examined under the...

Tsubaki A, Takai H, Oyanagi K, Kojima S, Tokunaga Y, Miyaguchi S, et al.
Adv Exp Med Biol . 2016 Aug; 923:159-166. PMID: 27526138
Near-infrared spectroscopy (NIRS) is a widely used noninvasive method for measuring human brain activation based on the cerebral haemodynamic response. However, systemic changes can influence the signal's parameters. Our study...
